Description:FIELD OF THE INVENTION

[0001] The present invention relates to the field of seats for vehicles, and more particularly to an integrated adaptive seating system for a vehicle configured to provide automated, personalized seating adjustments, vigorous ergonomic support, and enhanced safety through environmental responsiveness.

BACKGROUND OF THE INVENTION

[0002] Seats in vehicles, particularly two-wheelers, play a crucial role in determining rider comfort, posture ergonomics, and overall ride quality. Over the years, significant advancements have been made in improving seat designs to enhance cushioning, reduce vibration transmission, and provide better structural support. However, most of these improvements have been passive in nature, relying primarily on fixed geometry, foam density variation, or basic manual adjustments to accommodate different user requirements.

[0003] Another persistent challenge in two-wheeler seats arises from environmental exposure. Since most motorcycles and scooters are parked outdoors, the seats are frequently exposed to adverse weather conditions, including rain, dust, and intense sunlight. Moisture accumulation on seat surfaces can lead to slippage, affecting rider stability and safety, while prolonged exposure to environmental elements deteriorates seat materials over time. Existing solutions, such as waterproof seat covers or manual tarpaulin sheets, offer limited convenience and are often cumbersome to deploy or stow away.

[0004] Furthermore, seat comfort is significantly influenced by the dynamic interaction between the rider and the road surface. Road irregularities, vibrations, and sudden shocks directly impact the rider through the seat. While suspension systems in vehicles attempt to mitigate these effects, seat-level adaptivity to real-time road conditions remains largely unexplored in the context of two-wheelers.

[0005] DE19536041A1 discloses about a seat has a basic first seat attached to the motorcycle with a seating recess in the drivers position. The height of the first seat suits a small person. The first seat is completely functional in its own right. A removable second seat with an underside shaped to fit into the seating recess is attached around and on top of the first seat by a detachable holder system. When in position the height of the second seat suits a large person. The holder system may be made up of two-sided fixing joints that sit on the second seat, as side extensions of coating situated below and is laid flat. The seat may be made by forming a recess in a mass-produced standard seat, and adding a shaped cushion component.

[0006] US4462634A discloses about a two-part seat assembly for a motorcycle like vehicle has an operator's seat that is hingedly mounted to enable adjustment of its angle of inclination, and thereby to enable alteration of the operator's body attitude. Skirt portions are provided on the operator's seat to conceal the mechanism by which adjustment of the seat position is achieved, and to hide the frame parts and the concavity in which the operator's seat resides.

[0007] Conventionally, many systems have focused on improving seat comfort through structural modifications or material enhancements. However, these approaches predominantly rely on static configurations that fail to address the needs of different users and changing ride conditions. Existing solutions provide limited scope for user-specific customization, often requiring manual intervention for positional adjustments, which may not be feasible during active riding scenarios.

[0008] Furthermore, systems that address seat height variation or inclination adjustments are largely mechanical in nature and lack automation or control based on rider-specific data. Additionally, the problem of seat slippage in wet conditions remains inadequately addressed, with conventional designs offering rudimentary solutions such as slip-resistant seat covers that are neither responsive nor integrated within the vehicle’s functional ecosystem.

[0009] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a develop a more economically-producible seating system for two-wheelers that is capable of adapting to user-specific ergonomic preferences and external riding conditions, without requiring manual adjustments. Such a system should facilitate automated customization of seating configurations based on user identification, enhance ride comfort by responding to real-time vehicle dynamics and environmental factors, and offer integrated protective features to maintain seating safety and usability under varying weather conditions. The system should be designed to seamlessly integrate within the compact structural framework of two-wheelers for ensuring ease of use, operational efficiency, and improved rider experience.

OBJECTS OF THE INVENTION

[0010] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0011] An object of the present invention is to develop a seating system that automatically adjusts to an individual user's ergonomic preferences using personalized data for enhanced comfort and convenience.

[0012] Another object of the present invention is to ensure that the seating adjustments are securely personalized and accessible only to authorized users through a secure authentication process.

[0013] Another object of the present invention is to offer cushioning that adapts in real-time to the user's body weight distribution for ensuring optimal support and minimizing fatigue during travel.

[0014] Another object of the present invention is to enhance user comfort by automatically modifying seating parameters based on vehicle motion dynamics and varying road conditions.

[0015] Another object of the present invention is to improve user safety and comfort by enhancing the surface grip of the seating surfaces in response to wet or slippery conditions.

[0016] Yet another object of the present invention is to provide protective measures that shield the seating area from environmental factors such as rain or dust, thereby maintaining seating hygiene and user comfort.

[0017] The foregoing and other objects, features, and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.

SUMMARY OF THE INVENTION

[0018] This summary is provided to introduce a selection of concepts in a simplified format that are further described in the detailed description of the disclosure. This summary is not intended to identify key or essential inventive concepts of the disclosure, nor is it intended for determining the scope of the disclosure.

[0019] The present invention relates to an integrated adaptive seating system for a vehicle, specifically suited for two-wheeler vehicles, which enables automated and personalized adjustment of seat parameters in response to user-specific preferences and dynamic riding conditions that adapts to ergonomic requirements, environmental factors, and vehicle dynamics, thereby enhancing rider comfort, safety, and convenience.

[0020] In accordance with an aspect of the invention, an integrated adaptive seating system for a vehicle, comprises a biometric authentication unit configured to receive biometric information of a user for identifying and fetching pre-stored seating preferences from a linked database. A user interface module is provided to facilitate the user in inputting personal seating preferences, wherein the preferences are securely linked with the biometric data of the user. A proximity sensor is embedded within a steering unit of the vehicle to detect the presence of a user, thereby activating the biometric authentication unit for initiating the personalization sequence.

[0021] The system further comprises a primary seat adjustably mounted onto the vehicle through a mounting arrangement designed to facilitate horizontal and vertical adjustment of the primary seat in accordance with user preferences. The mounting arrangement includes a frame structure integrated with a sliding rack for horizontal seat adjustment, wherein the position of the rack is lockable within the frame using a plurality of spring-loaded pins. Vertical adjustment of the primary seat is enabled through a plurality of linear actuators operatively connected between the frame and the vehicle’s surface.

[0022] To provide dynamic cushioning comfort, the primary seat is equipped with a cushion unit comprising a plurality of air pockets arranged over the seat surface. An inflation unit is provided to selectively inflate the air pockets in response to weight distribution data detected by a grid of load cells embedded within the primary seat structure. The cushion unit thereby ensures adaptive pressure distribution to enhance user comfort during varying riding conditions.

[0023] In another aspect of the present invention the system includes a convertible secondary seat mounted with the primary seat, which is configured to transform into a backrest for the primary seat as per user preference. The secondary seat is connected through a convertible arrangement comprising a pair of guide bars affixed to the rear portion of the primary seat and a hinge provided over a carriage assembly coupled with the guide bars. The arrangement enables both orientation and vertical adjustment of the secondary seat relative to the primary seat, thereby allowing the secondary seat to function as an adjustable backrest or a pillion seat as desired.

[0024] The system further incorporates a sensing unit configured to determine the speed of the vehicle and the type of road the vehicle is driven on, facilitating automatic adjustment of the cushion unit and the secondary seat to enhance rider comfort. The sensing unit comprises a GPS (Global Positioning System) module and a camera unit mounted on the vehicle for capturing real-time images of the road surface.

[0025] To address the challenge of seat slippage in wet conditions, a grip enhancing arrangement is provided over the primary and secondary seats. The grip enhancing arrangement comprises a plurality of inflatable ridges embedded within the upper seat surfaces, wherein the ridges are selectively inflated by inflators integrated within the seat structure upon detection of moisture. The detection of moisture is achieved through a sensing means comprising a network of capacitive sensors layered over the seat surfaces for enabling the system to dynamically activate the grip enhancement feature when required.

[0026] Additionally, the system is provided with a cover unit integrated within the secondary seat, which is configured to deploy a weather-protective cover over the primary seat. The cover unit comprises an extendable rod housed within a recess underneath the secondary seat and a collapsible canopy attached to the rod, thereby providing protection against environmental factors such as rain and dust when the vehicle is stationary.

[0027] To further clarify the advantages and features of the system, a more particular description of the system will be rendered by reference to specific embodiments thereof, which is illustrated in the appended drawing. It is appreciated that these drawings depict only typical embodiments of the disclosure and are therefore not to be considered limiting its scope.

DETAILED DESCRIPTION OF THE INVENTION

[0035] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0036] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0037] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0038] The present invention relates to an integrated adaptive seating system for a vehicle configured for use in vehicles, particularly two-wheelers, which enables automated and user-specific customization of seating parameters to enhance ergonomic comfort, riding posture, and operational safety. The system is designed to adapt to individual user preferences and varying ride conditions under diverse operational scenarios, including adverse weather and varying road surfaces.

[0039] Figure 1 exemplarily illustrates a perspective view of an integrated adaptive seating system configured with a vehicle 100, comprises of biometric authentication unit 101 mounted on the vehicle 100, a proximity sensor 102 embedded in a steering unit of the vehicle 100, a primary seat 103 installed adjustably with the vehicle 100 by means of a mounting arrangement 104, a convertible secondary seat 105 installed with the primary seat 103 by means of a convertible arrangement 106 and a camera 107 installed on the vehicle 100.

[0040] The system disclosed herein includes a biometric authentication unit 101 mounted on a two-wheeler vehicle 100 that is designed to receive biometric information such as a fingerprint, facial recognition data, iris scan, or other unique physiological identifiers of a user, which is then utilized to fetch pre-stored personal seating preferences from a linked database. This ensures that the vehicle 100 seating automatically adjusts to the specific ergonomic and comfort preferences of each authorized user without requiring manual intervention, each time the vehicle 100 is accessed.

[0041] Complementing the biometric authentication unit 101, is a user interface module that facilitates users to initially feed and update their personal seating preferences. In one embodiment the user interface module is presented as a touchscreen display. In another embodiment, the user interface is a mobile app interface, or even an integrated voice-command means installed on the vehicle 100. During the initial setup, the user inputs their seating preferences, which include parameters such as height of seat (103,105), inclination angle, lumbar support level, cushion firmness, backrest orientation, and other ergonomic factors. Importantly, these preferences are securely associated with the user's biometric profile for ensuring that only the authenticated individual access, modify, or trigger these personalized configurations. In an exemplary embodiment, a user might prefer a higher seating position with firm lumbar support, while another family member might favor a reclined backrest with softer cushioning. The user interface module stores these preferences for seamless recall.

[0042] A proximity sensor 102 is embedded within a steering unit of the vehicle 100 for initiating the authentication sequence in a contactless and user-friendly manner. When the user approaches the vehicle 100, the proximity sensor 102 detects the presence of the individual based on their spatial position relative to the steering unit. Upon detection, the proximity sensor 102 triggers the activation of the biometric authentication unit 101 to begin the process of identifying the user. This ensures that the seating system remains in a dormant state, conserving energy and preventing unnecessary adjustments, until the presence of the user is confirmed.

[0043] Once activated, the biometric authentication unit 101 scans the presented biometric data and performs a secure comparison against the stored profiles within the vehicle’s onboard or cloud-linked database. Upon successful authentication, the system retrieves the corresponding personal seating preference profile and proceeds to adjust various seating orientation and height to precisely match the authenticated user's stored configurations.

[0044] The biometric authentication is implemented, in an embodiment of the present invention, through a fingerprint scanner seamlessly embedded on the steering unit’s surface for allowing the user to naturally place their finger while gripping the steering.

[0045] In another embodiment of the present invention, facial recognition sensors are strategically positioned on the dashboard or rear-view mirror area to scan the user’s face when user accesses the vehicle 100 incorporated within the biometric authentication unit 101. The biometric authentication unit 101 is designed to function swiftly for ensuring minimal latency between user access to the vehicle 100 and seating adjustment initiation.

[0046] Furthermore, in case of multi-user profiles, the system is configured to prioritize profiles based on a scheduling protocol, usage frequency, or manual override through voice commands for ensuring operational flexibility. Additionally, failsafe means, such as manual adjustment overrides and redundant control means are implemented to maintain functionality in case of any malfunctions, thus enhancing reliability.

[0047] Figure 2 exemplarily illustrates a perspective view of the system, the system comprising the primary seat 103 mounted with the vehicle 100 by means of a mounting arrangement 104, a plurality of linear actuators 201 include within the mounting arrangement 104, a cushion unit 202 installed with the primary seat 103, a plurality of air pockets 203 arranged over the primary seat 103, an inflation unit 204 provided with the primary seat 103, a plurality of load cells 205 integrated with the primary seat 103, a grip enhancing arrangement 206 provided over the primary seat 103 and the secondary seat 105 and a sensing means 207 layered over the upper surfaces of the primary seat 103 and the secondary seat 105.

[0048] Figure 3 exemplarily illustrates a perspective view of the mounting arrangement 104 configured with the system, the mounting arrangement 104 comprises of a frame 301 provided with a sliding rack 302 and a sliding channel 303 connected with the primary seat 103 and a plurality of spring-loaded pins 304 is provided with the frame 301.

[0049] The primary seat 103 is installed adjustably onto the two-wheeler’s chassis frame via the mounting arrangement 104 that facilitates bi-axial (horizontal and vertical) adjustments of seats (103,105). The mounting arrangement 104 comprises a structurally reinforced seat frame 301 that is affixed onto the existing rear sub-frame of the two-wheeler chassis. The frame 301 is configured with the sliding rack 302 that is integrated longitudinally along the seat’s underside for enabling forward and backward movement of the primary seat 103 relative to the chassis.

[0050] The sliding rack 302 is designed with a series of precision-machined grooves or detent notches, spaced at uniform intervals, which serve as discrete locking positions for horizontal adjustment of seat 103. The frame 301 housing the rack 302 is rigidly affixed to the rear sub-frame of the two-wheeler chassis for ensuring structural stability and alignment accuracy. The user is able to adjust the position of the seat 103 along a predefined track length, ranging from a 50-70mm range, which is ergonomically sufficient to accommodate riders of varying torso lengths and arm reaches.

[0051] The sliding action of the primary seat 103 along the rack 302 is facilitated by low-friction linear bearings and sliding channel 303, which are mounted within the interface between the seat 103 and the rack 302. These bearings ensure smooth, controlled movement of the primary seat 103 with minimal resistance for allowing the user to manually slide the seat 103 forward or backward with ease, even while seated.

[0052] In an embodiment of the present invention, the sliding grooves are coated with polytetrafluoroethylene (PTFE) based low-friction materials to further reduce wear and ensure longevity of the adjustment means under repeated use.

[0053] To ensure precise control over positioning of the seat 103, especially critical in a two-wheeler where rider-seat coupling impacts balance and safety, the sliding rack 302 is equipped with a plurality of spring-loaded locking pins 304. These pins 304 are strategically located on the frame 301 and are designed to interface with pre-drilled locking holes or detent notches along the sliding rack 302. When the seat 103 is adjusted forward or backward to the rider’s desired position, the spring-loaded pins 304 engage into the corresponding notches, providing a mechanically positive lock that secures the seat’s position for preventing any unintended shift during dynamic riding conditions such as acceleration, braking, or cornering.

[0054] In an embodiment of the present invention, the locking pins 304 are manually retractable through a user-operable lever means for allowing the rider to disengage the pins 304, adjust the seat 103, and release the lever to lock the seat 103 into a new position.

[0055] In another embodiment of the present invention, particularly suited for premium two-wheeler variants, the locking pins 304 are actuated electrically through micro-solenoids, controlled via a handlebar-mounted switch or a touch-sensitive control panel. Upon activation, the solenoids retract the pins 304 against spring tension for allowing motorized or manual adjustment of seat 103, and upon release, the pins 304 re-engage into the nearest detent notch automatically.

[0056] Vertical adjustment of the seat 103, while traditionally absent in two-wheeler seats, is incorporated through plurality of linear actuators 201 mounted between the frame 301 of the seat 103 and the chassis frame that are designed to provide a vertical adjustment preferably ranging approximately 20-30mm. This range, though seemingly modest, is highly impactful in the two-wheeler domain for allowing riders to modulate height of seat 103 for better foot reach to the ground or a more aggressive riding posture, depending on individual preference and riding conditions (urban commute vs long rides).

[0057] In an embodiment optimized for scooters, the vertical adjustment leverages adjustable linkage arms with cam locks, where a rider may select predefined height settings. In contrast, for high-performance motorcycles, motorized linear actuators 201 controlled via handlebar-mounted switches or mobile app interfaces offer fine-tuned real-time height adjustments of seat 103.

[0058] In another embodiment, the linear actuators 201 are manually operated, wherein the rider adjust height of the seat 103 by rotating a mechanical knob or lever integrated discreetly beneath the seat edge.

[0059] In yet another embodiment, the actuators 201 are motorized, responding to electronic control signals received from a user interface module, enabling real-time height adjustment of the seat 103 even while the vehicle 100 is stationary. The motorized actuators 201 are equipped with position feedback sensors for ensuring precise control over seat 103 elevation and preventing over-extension beyond design limits.

[0060] In an exemplary embodiment of the present invention that involves a two-wheeler shared by multiple users, where a taller rider prefers a rearward and slightly elevated seat 103 position for a sporty riding stance, while a shorter rider requires the seat 103 to be moved forward and lowered to ensure comfortable reach to handlebars and footrests. Upon user authentication (via biometric authentication unit 101), the seat’s sliding rack 302 adjusts horizontally, and the vertical actuators modulate the seat 103 height to match the stored profile for ensuring an ergonomically optimized riding posture for each user.

[0061] Given the criticality of weight distribution and center of gravity (CoG) in the two-wheeler, the mounting arrangement 104 of the seat 103 is designed to ensure that adjustments in seat 103 position do not adversely affect the vehicle’s balance and handling dynamics. The entire seat 103 maintains a low-mass construction, utilize materials that includes but not limited to a magnesium alloys, carbon-fiber-reinforced plastics (CFRP) for non-structural components, while critical load-bearing elements utilize aircraft-grade aluminum or titanium alloys.

[0062] In an embodiment of the present invention, the seat 103 designed for adventure motorcycles having the mounting arrangement 104 may integrate shock-damping elastomers or viscoelastic pads between the seat frame 301 and chassis mount points to provide additional vibration isolation, thus enhancing rider comfort during off-road conditions while retaining seat 103 adjustability.

[0063] Importantly, the modularity of the mounting arrangement 104 ensures compatibility across multiple two-wheeler platforms, whether commuter scooters, sport bikes, or touring motorcycles, facilitating OEM (Original Equipment Manufacturer) level integration as well as aftermarket retrofitting.

[0064] A cushion unit 202 installed with the primary seat 103 designed to deliver real-time adaptive cushioning customized to the individual rider’s body posture, weight distribution, and ride conditions. The cushion unit 202 transcends conventional foam-based padding by integrating a network of inflatable air pockets 203, load sensing, and inflation control to create a responsive seating surface that continuously adjusts to provide optimal support and comfort.

[0065] The cushion unit 202 is integrated into the primary seat's upper surface, forming a thin yet strong configuration that maintains the aesthetic and ergonomic profile typical of two-wheeler seats. The cushion unit 202 comprises a matrix of air pockets 203 that are small, independently inflatable chambers arranged in a grid pattern across the seat’s seating area, including key pressure zones such as the rider's ischial (sit bones) region, thighs, and lower back support area.

[0066] These air pockets 203 are fabricated from high-durability elastomeric materials, that include but not limited to thermoplastic polyurethane (TPU) or silicone composites for ensuring they withstand repetitive inflation-deflation cycles, rider-induced shear forces, and varying environmental conditions (temperature, humidity). The air pockets 203 are interconnected through a network of micro-channels, each controlled via a central inflation unit 204.

[0067] Beneath the cushion unit 202, embedded within the seat 103 pan structure, a grid of miniature load cells 205 is installed. These load cells 205 are precisely distributed to form a high-resolution weight mapping array that is capable of detecting micro variations in weight distribution across the surface of the seat 103. Each load cells 205 functions by converting applied mechanical pressure into electrical signals, which are processed by an onboard control module to generate a real-time pressure map of the rider's seating posture.

[0068] In an exemplary embodiment of the present invention, if a rider shifts their weight during a turn or while riding on an uneven road, the load cells 205 in the affected area detect increased pressure, prompting the system to adjust the air pockets 203 dynamically to redistribute support, thereby reducing localized discomfort and maintaining a balanced posture.

[0069] The inflation unit 204 serves as the core actuator means of the cushion unit 202. The inflation unit 204 comprises a miniaturized air compressor or micro-blower, integrated with precision-controlled solenoid valves or piezoelectric micro-valves. The compressor is designed to operate silently and efficiently which is capable of delivering precise air volumes to individual air pockets 203 within milliseconds for ensuring that cushioning adjustments occur in real-time without perceptible delay to the rider.

[0070] A dedicated Electronic Control Unit (ECU) interfaces with the load cells 205 for continuously analyzing the pressure data to determine the necessary inflation levels for each air pocket 203. The ECU operates on adaptive protocols, possibly incorporating machine learning techniques to predict rider posture patterns over time, further enhancing the system's responsiveness.

[0071] Considering a two-wheeler commuter scenario, where the rider navigates through stop-and-go traffic. During prolonged stops, the system detects a static seating posture and adjusts the air pockets 203 to reduce pressure buildup on the rider's sit bones for enhancing comfort during idle periods. Conversely, during dynamic riding situations, such as accelerating from a stop or leaning into a corner, the system responds by firming up air pockets 203 in areas experiencing increased load shifts, thereby offering enhanced support and reducing rider fatigue.

[0072] In a touring motorcycle scenario, the cushion unit 202 is configured for long-distance endurance riding, where gradual shifts in rider posture over hours of continuous riding are anticipated. Here, the cushion unit 202 is pre-fed to periodically modulate the air pressure distribution even in the absence of drastic weight shifts for preventing the onset of numbness or discomfort from prolonged static postures.

[0073] In an embodiment of the present invention, the cushion unit 202 provides a variety of modes that are controlled by the user via user-interface. The modes include:

• User-Selectable Comfort Modes: The cushion unit 202 offer multiple pre-set comfort profiles selectable via a handlebar-mounted control switch or the user- interface. Modes such as "Soft Comfort Mode" for city commutes, "Firm Sport Mode" for aggressive riding, or "Dynamic Adaptive Mode" for mixed conditions are provided for allowing riders to customize the cushioning behavior as per their preferences.

• Posture Correction & Ergonomics: The data of the load cell 205 is utilized not just for comfort but for posture correction. In an exemplary embodiment of the present invention, if the rider is leaning asymmetrically for an extended duration, the system detects the imbalance and subtly adjust air pockets 203 to nudge the rider back into a neutral spine-aligned posture, thereby reducing long-term musculoskeletal strain.

• Temperature-Controlled Cushioning: For premium variants, the cushion unit 202 may integrate thermo-regulating layers with active air-flow channels. The inflation unit 204 may facilitate ventilation through selective air pockets 203, allowing cool air to circulate on hot days or warm air during cold conditions, further enhancing rider comfort.

• Load-Adaptive Suspension Coupling: In performance-focused motorcycles, the load data from the cushion unit 202 may be shared with the vehicle’s suspension control system for enabling real-time adjustments of suspension damping based on rider posture shifts, thus achieving a holistic ride dynamics management.

[0074] To ensure operational safety, the cushion unit 202 is designed with a default neutral configuration. In case of system failure (electrical malfunction, air leakage, etc.), the cushion defaults to a medium-firm state for allowing the rider to continue operation without significant discomfort or safety risk. Manual override valves or quick-deflate means are also incorporated for emergency scenarios.

[0075] In an exemplary embodiment of the present invention, a rider embarking on a long-distance highway ride. Initially, the inflation unit 204 inflates the lower back support air pockets 203 to encourage an upright posture. As the ride progresses, if the load cells 205 detect increased pressure on one side (indicating rider shifting or fatigue), the inflation unit 204 dynamically compensates by inflating adjacent pockets 203 in view of distributing weight evenly. Upon encountering rough road patches, the cushion unit 202 momentarily softens air pressure in high-impact zones to dampen shocks, providing a “floating seat effect.”

[0076] Figure 4 exemplarily illustrates a perspective view of the system in a backrest configuration by means of the convertible arrangement 106, the convertible arrangement 106 comprises of a pair of guide bars 401 attached with a rear portion of the primary seat 103 and a pair of hinges 402 attached with the guide bars 401.

[0077] The primary seat 103 is installed with the convertible secondary seat 105 that is designed to transform seamlessly into a backrest for the primary seat 103, thereby enhancing rider ergonomics, comfort, and versatility. Unlike conventional pillion seats that are fixed in position or simplistic fold-down backrests with limited adjustability, the secondary seat 105 is a fully adjustable, convertible, reposition, and adaptable to suit various riding conditions and user preferences.

[0078] The secondary seat 105 is structurally integrated with the rear portion of the primary seat 103 via the convertible arrangement 106. The convertible mounting arrangement 104 comprises a pair of rigid guide bars 401, which extend rearward from the primary seat frame 301. These guide bars 401, fabricated from high-strength yet lightweight materials that includes but not limited to aircraft-grade aluminium alloys or carbon-fiber composites, act as the primary structural linkage between the primary seat 103 and the secondary seat 105. Each guide bar 401 is configured to be slidably interfaced with a carriage unit, wherein the carriage serves as the mobile anchoring point for the secondary seat 105.

[0079] In an embodiment of the present invention, the guide bars 401 are configured as telescopic assemblies, comprising an outer stationary tube fixed to the primary seat frame 301 and an inner sliding rod coupled with the carriage unit. The telescopic nature of the guide bars 401 allows for a compact retraction when the secondary seat 105 is in its default horizontal configuration, while enabling smooth extension when vertical adjustment of the secondary seat 105 is required.

[0080] In another embodiment of the present invention, the guide bars 401 are facilitated through integrated lead screw arrangement, wherein a threaded rod is fixed within the stationary tube, and a matching threaded nut is affixed to the inner sliding rod. When rotational torque is applied to the lead screw, either manually via an adjustment knob or automatically through a micro electric motor, the threaded nut travels along the lead screw axis, causing the sliding rod to extend or retract. The lead screw arrangement enables precise control over the vertical positioning of the carriage for allowing riders to finely adjust the height of the secondary seat 105 to suit individual ergonomic needs.

[0081] In another embodiment for entry-level commuter scooters, the telescopic guide bars 401 is manually adjustable, wherein the user may rotate a knurled adjustment knob positioned discreetly beneath the secondary seat 105 to extend or retract the guide bars 401. A click-stop detent means integrated within the lead screw assembly provides tactile feedback and locks the height of the seat 103 at discrete intervals, ensuring positional stability during ride vibrations.

[0082] In yet another embodiment, in case of touring motorcycles, the guide bars 401 are actuated electronically, wherein a compact DC motor coupled with a worm gear reduction means rotates the lead screw upon receiving commands from a handlebar-mounted control switch. This allows the rider to adjust the backrest height even while stationary on the vehicle 100, providing effortless adaptability during long-distance rides.

[0083] Each guide bar 401 is equipped with a pair of hinges 402 at both ends to provide multi-angle rotational adjustment of the secondary seat 105 relative to the primary seat 103. The hinge 402 comprises a dual-axis pivot joint, which allows the secondary seat 105 to rotate upwards from its default horizontal position into a vertical backrest configuration. The hinge 402 is integrated with a rotational locking means which may consist of spring-loaded detent pins or ratchet-based locking teeth, allowing the user to fix the backrest angle at predefined increments (such as every 10° within a 0° to 90° range).

[0084] In an embodiment of the present invention, the user manually disengages a release lever to unlock the hinges 402, rotate the secondary seat 105 to the desired inclination angle, and re-engages the lever to lock the hinges 402 in position. The locking means ensures that the secondary seat 105 remains firmly secured in the selected orientation, resisting displacement during acceleration, braking, or cornering forces.

[0085] In another embodiment, in case of high-end touring motorcycles, the hinges 402 is equipped with an electro-mechanical actuation means wherein a micro-linear actuator or servo-motor assembly controls the angular rotation of the backrest. The rider is able to adjust the recline angle through electronic controls, offering on-the-fly adaptability based on ride comfort or posture shifts during long journeys. The hinges 402 herein includes a position encoder that provides real-time feedback to the seating control in view of ensuring precise and repeatable angular adjustments.

[0086] In a default configuration, the secondary seat 105 remains aligned horizontally, functioning as a traditional pillion seat. However, when required, the user is able to initiate the conversion of the secondary seat 105 into the backrest. This is achieved by releasing the hinges 402 lock, rotating the secondary seat 105 upwards to the desired reclined or upright angle, and securing it via the hinges 402.

[0087] Once the secondary seat 105 is converted into the backrest, the vertical position adjustment allows the user to slide the backrest upwards or downwards to achieve precise lumbar or mid-back support, accommodating riders of varying torso lengths and postures.

[0088] In an exemplary embodiment of the present invention, where the rider uses the vehicle 100 for daily urban travel. During solo rides, the user may convert the secondary seat 105 into a lumbar backrest, adjusting its angle to provide additional lower back support, thereby reducing fatigue during stop-and-go traffic. If a pillion passenger needs to be accommodated, the user simply rotates the backrest forward, returning it to its horizontal position of seat 103, allowing the secondary seat 105 to function as a comfortable pillion seat.

[0089] In another embodiment of a touring motorcycle, the long-distance riders get benefit from this convertible arrangement 106 by configuring the secondary seat 105 as a full-height ergonomic backrest, perhaps even in combination with the adaptive cushion unit 202. For endurance rides, the backrest may be reclined slightly to reduce spinal load, adjusted vertically to target specific back regions, and locked securely to maintain its position across varying road conditions.

[0090] The system interface with the vehicle’s biometric authentication unit 101, allowing pre-configured backrest positions and orientations to be auto-adjusted based on user profiles. For example, User A may prefer an upright lumbar support position, while User B prefers a reclined mid-back support; upon authentication, the system recall and adjust accordingly.

[0091] In an embodiment of the present invention, sensors may be employed for monitoring rider posture shifts or road inclination that trigger micro-adjustments of the backrest orientation and height in real-time, ensuring sustained rider comfort during extended journeys or varying road terrains (e.g., uphill rides, uneven surfaces).

[0092] In an embodiment of the present invention, the secondary seat 105 is also equipped with the cushion unit 202 similar in functional design to that of the primary seat 103. This cushion unit 202 comprises series of air pockets 203 embedded within the surface of the secondary seat 105, arranged to provide targeted support when the seat 105 is used in its horizontal pillion configuration or in its upright series of air pockets 203 backrest mode. The air pockets 203 are connected to the shared inflation unit 204, allowing synchronized or independent control of pressure levels based on the usage mode.

[0093] When functioning as the backrest, the air pockets 203 are selectively inflated to provide lumbar or thoracic support, ensuring enhanced rider comfort during long rides. The cushion unit 202 in the secondary seat 105 may also be integrated with load cells 205 for enabling dynamic adjustment in response to the posture or pressure exerted by the rider’s back, similar to the base of the seat 105. This configuration offers improved spinal alignment and vibration absorption, contributing to overall ergonomic support.

[0094] A sensing unit is installed on the vehicle 100 that actively monitors both dynamics (speed) of vehicle 100 and external road conditions to enable real-time automated adjustments of the seating system, specifically the cushion unit 202 and the convertible secondary seat 105 (backrest). The sensing unit forms the critical feedback loop that ensures the seating configuration dynamically adapts to optimize rider comfort, reduce fatigue, and enhance riding safety across varying environmental and vehicular conditions.

[0095] The sensing unit comprises a GPS (Global Positioning System) module, and a camera 107 mounted on the vehicle 100 that provide a comprehensive situational awareness for enabling the vehicle’s adaptive seating system to receive continuous data streams about the vehicle’s speed, geolocation, road type, and surface quality.

[0096] The GPS module, integrated into the vehicle's electronic control architecture, serves a dual function. First, it provides accurate speed data of vehicle 100, which is essential for adjusting the cushion unit 202 stiffness and the backrest's inclination based on riding conditions. Unlike traditional speedometers, GPS-derived speed measurements offer an added layer of precision by factoring in gradient variations and GPS trajectory corrections, thereby ensuring reliable feedback even in varying load scenarios.

[0097] Second, the GPS module interfaces with geospatial databases and digital mapping services in view of enabling the sensing unit to determine the type of road or terrain the vehicle 100 is traversing. For example, the system is able to discern whether the vehicle 100 is operating on a smooth urban asphalt road, a bumpy rural path, or a winding mountain trail. By cross-referencing real-time GPS coordinates with pre-mapped terrain data, the system anticipates potential discomfort factors and prepares the seating system to proactively adjust.

[0098] For example, when the GPS indicates that the vehicle 100 is transitioning from a highway onto a rough countryside road, the control system may trigger softening of the cushion air pockets 203 to improve shock absorption and adjust the backrest angle to a more upright position, enhancing rider stability and reducing impact forces on the spine.

[0099] Complementing the GPS module, a high-resolution camera 107 is strategically installed on the two-wheeler, typically mounted on the front fairing, handlebar assembly, or under the headlamp cluster, with a forward-facing field of view. The camera 107 captures live visual data of the road surface ahead, which is processed by an onboard image processing unit.

[00100] The processing unit is designed to analyze the texture, color patterns, and surface anomalies of the road in real-time. Through image processing protocols (such as convolutional neural networks (CNNs)), the system is able to accurately detect potholes and cracks, uneven surfaces or gravel patches, wet or slippery sections and lane patterns, curvatures, and speed humps.

[00101] Upon detecting such features, the system classifies the severity of the road condition and accordingly sends command signals to the seating control ECU to adapt the firmness of the cushion unit 202 and adjust the secondary seat’s (backrest) orientation or position to mitigate discomfort.

[00102] In an exemplary embodiment of the present invention, the commuter scooter navigating through city traffic. As the GPS module confirms urban grid coordinates and vehicle 100 speed remains below 30 km/h, the sensing unit configures the cushion unit 202 to a softer profile, enhancing plushness for stop-and-go conditions. Upon detecting an approaching speed hump via the camera 107, the system momentarily firm up the cushion to prevent bottoming-out impacts while also adjusting the backrest to an upright position to stabilize the rider’s posture.

[00103] In another embodiment of the present invention involving the touring motorcycle, where prolonged highway cruising is common, the GPS unit detects a consistent high-speed run above 80 km/h on smooth tarmac. The system accordingly firms up the cushion air pockets 203 to provide adequate support and gradually reclines the backrest to a relaxed posture. However, upon entering a stretch with rough road patches (detected visually by the camera 107), the system dynamically softens the seat 103 cushioning in impacted zones, and adjusts the backrest angle to offer better spinal support for ensuring rider comfort without manual intervention.

[00104] The system preemptively adjusts the seating parameters by analyzing upcoming road conditions based on GPS-mapped elevation data (such as steep climbs or descents) and adjusting backrest orientation for better rider stability.

[00105] Depending on rider-selected comfort modes (City, Sport, Touring), the sensing unit modulates how aggressively the cushion unit 202 reacts to road imperfections. For example, in “Touring Mode,” the cushion may be tuned to prioritize plushness, while “Sport Mode” prioritize stability by maintaining firmer cushioning.

[00106] Over time, the system learns from the rider’s manual adjustments in response to certain road conditions, refining its auto-adjustment protocols through AI-based learning, thereby personalizing the experience further.

[00107] In an embodiment of the present invention, the sensing unit integrates accelerometers and gyro sensors to capture real-time vibrations and angular displacement data, which when fused with GPS and visual inputs, results in ultra-precise seat 103 adjustment feedback. The camera 107, in combination with capacitive moisture sensors, may detect wet road conditions (reflected glare, color anomalies) and adjust seating firmness to prevent rider instability caused by slip-prone surfaces.

[00108] Given the real-time operational nature of the sensing unit, fail-safes are incorporated to ensure that in case of malfunction or environmental constraints (e.g., low visibility conditions impacting the camera 107), the default neutral seat configuration prioritizes balanced comfort and stability. Manual override options through handlebar controls or interfaces allow the rider to assume control when desired.

[00109] A grip enhancing arrangement 206 provided over the primary seat 103 and the secondary seat 105 are specifically designed for two-wheeler seating systems to address one of the most critical challenges faced by riders: surface slippage under wet conditions. The grip enhancing arrangement 206 comprises a series of inflatable ridges integrated seamlessly onto the upper surfaces of both the primary seat 103 and the convertible secondary seat 105 (backrest/pillion seat), which are selectively actuated to enhance surface friction for ensuring that the rider and passenger maintain a secure seating position even in adverse weather conditions like rain, fog, or humid environments.

[00110] The grip enhancing arrangement 206 is embedded directly into the outer upholstery layer of the seats (103, 105), which is fabricated from high-durability elastomeric or neoprene-based materials. These materials inherently offer moderate anti-slip characteristics under dry conditions but become susceptible to reduced friction coefficients when exposed to moisture. To counteract this, a network of inflatable ridges (grip ribs) is incorporated beneath the upholstery's outermost layer.

[00111] These inflatable ridges are strategically arranged in preferably concentric grid pattern across the seating area, particularly concentrated around high-contact zones such as the thigh support areas, ischial (sit bones) region, and lower lumbar section of the backrest. The ridges are designed as tubular air chambers which, when inflated, protrude subtly above the baseline seating surface, increasing surface texture and thereby enhancing grip through mechanical interlocking with the rider’s clothing and by augmenting micro-surface friction.

[00112] The inflatable ridges are fabricated using high-elasticity thermoplastic polyurethane (TPU) films known for their flexibility, puncture resistance, and high fatigue endurance across inflation-deflation cycles. The inner walls of these ridges are reinforced with micro-structured anti-slip textures, such as hexagonal or diamond-patterned surface laminates, to further augment grip once deployed.

[00113] The inflation and deflation of the ridges are managed by miniaturized inflator units, integrated discreetly within the primary seat 103 pan structure and the secondary seat's housing. These inflators may utilize compact air pumps (micro-blowers) or pre-compressed air cartridges (in few embodiments) for rapid actuation. The inflators are electronically controlled by a Seating Control Unit (SCU) interfaced with the vehicle 100, which receives signals from a sensing means 207 embedded within the surface layers of the seats (103, 105).

[00114] When the sensing means 207 detect the presence of moisture, for example, due to rainfall or condensation, the SCU triggers the inflation of the ridges within milliseconds, creating a dynamically enhanced surface profile that counters the slipperiness introduced by the wet surface. Conversely, once dry conditions are detected, or if the user manually deactivates the feature, the system deflates the ridges, allowing the seat 105 to return to its default smooth, streamlined profile, ensuring optimal comfort during dry riding conditions.

[00115] In an exemplary embodiment of the present invention, the commuter scooter, where the vehicle 100 frequently is parked in open environments exposed to rainfall, the system proves invaluable. Upon ignition start, the moisture sensors conduct a quick surface scan. If residual water droplets are detected, the system automatically inflates the ridges before the rider mounts the vehicle 100, ensuring a stable and slip-free ride initiation. During the ride, if sudden rainfall occurs, the system responds, inflating the ridges in real-time, providing additional safety without any user intervention.

[00116] For a touring motorcycle designed for long-distance travel across variable terrains and weather conditions, the grip enhancing arrangement 206 adds significant rider safety and comfort. On encountering wet patches, such as while riding through foggy mountainous regions, the system's inflatable ridges deploy to maintain secure seating, especially during sharp turns or sudden braking maneuvers, where even minor slippage may impact rider control. Furthermore, for pillion passengers, the secondary seat’s inflatable ridges are selectively activated based on passenger presence detection, ensuring adaptive comfort without compromising the seat’s aesthetics when not in use.

[00117] In an embodiment of the present invention, the system offers user-selectable profiles where the intensity and pattern of ridge inflation are customized. For example, a “High-Grip Mode” inflates all ridges for maximum traction during heavy rainfall, while a “Comfort Mode” inflates only select ridges to balance grip with seating softness.

[00118] For enhanced ergonomics, the ridges are designed with a shape-memory polymer outer shell that retains a slight raised profile even when deflated for ensuring a baseline level of grip under all conditions without compromising comfort of seat 105.

[00119] Through a load cell 205 based occupancy detection, the secondary seat 105 ridges inflate only when the pillion passenger is detected in horizontal configuration, conserving energy and maintaining the aesthetic flat profile when unused.

[00120] Consider a rider starting their morning commute on a scooter after overnight rainfall. Upon system activation, the moisture sensors detect dampness, prompting immediate inflation of the grip ridges. The ridges subtly raise the seat's surface texture, providing additional grip that ensures the rider remains firmly planted during acceleration and deceleration in traffic. As the sun dries the seat (103, 105) during the day, the system detects the dry surface and automatically deflates the ridges, reverting the seat to its original smooth profile, thereby preventing discomfort during prolonged dry-weather riding.

[00121] In another scenario, a touring motorcyclist riding through intermittent showers benefits from real-time seat grip modulation, with the system inflating ridges dynamically as road spray or mist is detected in view of ensuring sustained seating grip through varying microclimates encountered along the ride.

[00122] The sensing means 207 comprises capacitive moisture sensors that are embedded within the topmost layers of the seat (103, 105) upholstery, designed in an ultra-thin, flexible grid formation that overlays the seat's surface without altering its ergonomic contours or aesthetics. Each sensor operates by generating a low-intensity electric field across a defined sensing area. When the surface of the seat (103, 105) is dry, the sensor maintains a baseline capacitance value. However, when moisture (such as water droplets, condensation, or sweat) accumulates on the surface of the seats (103, 105), the dielectric properties of the surface change, leading to a detectable variation in the sensor’s capacitance.

[00123] These minute changes in capacitance are continuously monitored by a Sensor Processing Unit (SPU), which is interfaced with the vehicle’s Seating Control ECU. The SPU is calibrated to distinguish between light moisture presence (mist or condensation) and heavy wetting (rainwater accumulation), allowing the system to determine the appropriate responsive action. For example, a light dew presence may only trigger modest inflation of grip-enhancing ridges, whereas substantial water detection may initiate full deployment of the grip ridges.

[00124] Figure 5 exemplarily illustrates a perspective view of the system in a weather protective configuration, comprises a cover unit 501 installed with the secondary seat 105, the cover unit 501 comprises an extendable rod 502, a recess 503 underneath the secondary seat 105, and a collapsible canopy 504 attached over the rod 502.

[00125] To further enhance the protective capabilities of the adaptive seating system, especially in scenarios where the vehicle 100 is parked in unpredictable weather, the system incorporates a compact, deployable cover unit 501 designed to shield the primary seat 103 from rain, dust, and direct sunlight. This cover unit 501 is ingeniously integrated within the secondary seat 105 structure, maintaining a low-profile, non-intrusive form factor that does not disrupt the aesthetic or functional utility of the two-wheeler when not in use.

[00126] An extendable rod 502 which is housed within a recess 503 beneath the secondary seat 105 (pillion seat) is designed to extend upwards and outwards when deployed, serving as the primary support mast. Attached to the extendable rod 502 is a collapsible canopy 504, crafted from weather-resistant materials like PU-coated ripstop nylon or laminated polyester fabrics for ensuring durability against rain, UV exposure, and dust ingress. The canopy 504 is developed with a foldable frame structure, incorporating flexible ribs that allow it to expand outward into a taut, protective covering over the primary seat 103 when deployed, and collapse neatly into a compact folded form when stowed.

[00127] The deployment of the cover unit 501 is actuated by a micro linear actuator. In an embodiment of the present invention, the rider may manually unlatch a quick-release catch hidden beneath the secondary seat 105, allowing the rod 502 to extend under spring tension, while the canopy 504 automatically unfolds into position through a series of self-aligning linkages. In another embodiment of the present invention, the deployment may be motorized and automated, controlled via the interface or a handlebar-mounted switch in view of enabling riders to deploy the canopy 504 remotely, for example, upon receiving a rain alert.

[00128] The Seating Control ECU regulates the automated deployment in response to moisture detection signals from the capacitive sensors. For example, if the sensors detect water presence beyond a predefined threshold (indicating sustained rainfall or heavy condensation) while the vehicle 100 is stationary, the system automatically deploy the canopy 504 to protect the surfaces of the seat (103, 105), preventing them from becoming saturated.

[00129] Considering a rider parks their scooter outdoors, and sudden rainfall occurs. The capacitive sensors detect water droplets forming on the surface of the seat (103, 105). The ECU evaluates the moisture persistence, and after a threshold duration (e.g., 15 seconds of continuous moisture detection), it initiates the deployment of the canopy 504. The hinges 402 enables the folding of the secondary seat 105 and the rod 502 extends from beneath the pillion seat, lifting the folded canopy 504, which then unfolds and locks into place for shielding the entire seat (103, 105) area from direct rainfall.

[00130] In an embodiment of the present invention, the canopy 504 may include a bifurcated rod, where the canopy 504 extends to protect not only the primary seat 103, but also partially shield the handlebar area, offering comprehensive weather protection.

[00131] In another embodiment of the present invention, upon retraction, the canopy 504 pass through an integrated squeegee means that removes accumulated water, ensuring the folded canopy 504 does not store moisture, which otherwise drip onto the seat (103, 105) after redeployment. For a touring motorcycle, the cover unit 501 may be particularly advantageous when the rider stops during a journey in unpredictable weather regions. By deploying the canopy 504, the rider ensures that upon return, the seating area remains dry and clean, thus eliminating the discomfort of sitting on wet surface or having to manually wipe down the seat (103, 105).
