A SEAT ASSEMBLY FOR A VEHICLE AND A METHOD THEREOF

APPLICANT:

TVS MOTOR COMPANY LIMITED, an Indian Company at: “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006.

The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[0001] The present subject matter relates generally to a vehicle, a seat assembly for the vehicle and the methods thereof. More particularly but not exclusively, the present subject matter relates to a vehicle, a seat assembly for the vehicle, a method to tumble the seat assembly from a first configuration to a second configuration and a method to tumble the seat assembly from the second configuration to the first configuration.

BACKGROUND
[0002] In conventional vehicles, such as in three-wheeled vehicles, the focus is primarily on improving the passenger seats to ensure the comfort and safety of occupants during transit. However, a significant challenge arises when attempting to incorporate carrying dual functionalities to carry cargo, goods and other non-passenger applications in addition to carry passengers into the existing seat structure while maintaining passenger comfort and safety standards. One of the key difficulties lies in the inherent lack of adaptability in existing seat structures in three wheeled vehicles for seamless integration of cargo utility. These seat structures are typically optimized for passenger comfort and safety, with limited provisions for accommodating additional cargo. Already existing approaches either involve complex retrofitting or require additional cargo-carrying accessories. Thus, conventional vehicles are inadequate in meeting the demands and preferences of modern customers, who are increasingly seeking multifunctional and adaptable vehicles.
[0003] The challenge becomes even more intricate upon considering the inclusion of components like a spare wheel and a portable charger, as it necessitates striking a delicate balance between the vehicle's primary function as a passenger carrier and its potential utility as a cargo-carrying vehicle. A portable charger and a spare wheel may be required in hybrid, electrical vehicle or even a vehicle with an internal combustion engine. Thus, such components may be indispensable whether the vehicle runs in passenger mode or the cargo/goods mode. In many vehicle layouts, the spare wheel is often stored in the floor assembly, utilizing the space underneath the cabin. However, in such configuration, the integrity of the valuable flat floor volume is not preserved as it becomes permanently occupied by the spare wheel, thereby making it unavailable for other potential uses like accommodating additional cargo. Another complication involved in the mounting of the spare wheel and the portable charger is the limited availability of space in the conventional locations within the vehicle. Therefore, it is apparent that conventional locations for spare wheel were either insufficient or impractical due to the specific layout of vehicle and structural constraints.
[0004] In the existing vehicle layout, the placement of the off-board charger under the driver's seat is also impractical due to restricted space which is already occupied by the battery pack. The interference of the off-board charger with the critical components such as battery is not desired. Another approach is to dispose the off-board charger remote to the battery disposed under the driver's seat. However, this leads to the issue of accessibility. Also, the off-board charger will be prone to theft and mishandling in such scenario. As a result, integrating cargo features such as a spare wheel and a portable charger becomes a significant technical challenge, often leading to a trade-off between passenger and cargo functionalities.
[0005] Another major constrains for adaptive and flexible seat structures, pertains to the accessibility of various components like Electric Drive Unit (EDU) and the junction box. Conventional layouts fail to dispose these components in readily accessible configuration. As a result, the servicing, maintenance and assembly process of these components is severely impacted. Also, the existing mounting configurations of the Electric Drive Unit (EDU) and the junction box adversely impact the structural integrity of the vehicle.
[0006] The problem becomes even more complicated and aggravated due to the ineffective and underutilization of the space within the interior of the vehicle. These constraints impose limitations on the overall functionality, versatility, usability, flexibility and adaptability of the vehicle, restricting its ability to efficiently switch between passenger and cargo modes based on transport requirements.
[0007] Therefore, there lies a challenge in finding a holistic technical solution that can address passenger comfort and safety concerns while enabling effective integration of the cargo functionality. Overcoming these technical hurdles is crucial for enhancing the practicality, functionality, usability, adaptability, versatility and utility of traditional vehicles, allowing them to adapt to diverse transportation needs seamlessly. It requires a holistic approach that takes the vehicle layout, engineering, and functionality aspects into consideration to achieve a harmonious balance between passenger and cargo functionalities without compromising either.
