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

TECHNICAL FIELD
Present disclosure generally relates to a field of automobiles. Particularly, but not exclusively the present disclosure relates to a seat of a vehicle. Further, embodiments of the present disclosure disclose a mechanism for unlocking a seat in a vehicle.
BACKGROUND
Generally, vehicles such as cars, sports utility vehicles (SUV’s), minivans and the like are provided with a boot portion at rear side of the vehicle to facilitate storage of luggage and other similar materials. However, due to increase in cabin space in the vehicles to comfortably accommodate the passengers, the dimensions of the trunk portion in the vehicles is reduced.
With advancements in technology, the vehicles are provided with provisions to increase the trunk portion capacity by folding the rear seats of the vehicles. Typically, the rear seat or the backrest of the rear seat is folded so as to increase the boot space. For example, the backrest of the rear seat is collapsed to a substantially flat position to increase the boot space, which in-turn increase of the luggage carrying volume in the boot space of the vehicle. Conventionally, in order to fold the rear seat backrest, an operator will have to open a tail gate and access the trunk portion to release a lock of the backrest. Additionally, a release knob or lever to unlock the backrest is located at ends of the seat which has to be accessed through the trunk portion of the vehicle. Generally, two levers are positioned at the top of the backrest, each at opposite corners. The operator will have to actuate each of the two levers separately at opposite corners, which is difficult to reach and requires individual operation, which is cumbersome and undesired.
The present disclosure is directed to overcome one or more limitations stated above, or any other limitation associated with the prior arts.

Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible, same numerals have been used to refer to the same or like parts. The following paragraphs describe the present disclosure with reference to Figs. 1-3.
Fig. 1, is an exemplary embodiment of the present disclosure illustrating a perspective view of a seat (200) of a vehicle. In an illustrated embodiment, the seat (200) is for a rear passenger seat of the vehicle. The seat (200) may include a base portion (14) and backrest portion (17) which may extend from the base portion (14). The back rest portion (17) may include a frame (20) on which a foam may be disposed for providing comfort to a commuter. Further, the seat (200) may include at least one latch (15) which may be connected to the frame [i.e., back rest frame]. The at least one latch (15) may be configured to selectively lock and unlock the frame (20) with a body of the vehicle. In an embodiment, the at least one latch (15) may be configured to lock and unlock the frame (20) with a locking member [not shown in Figs] which may be disposed on the body of the vehicle. For example, the locking member may be including but not limited to a projection, a stub, a hook and any other means suitable for receiving a portion of the at least one latch (15) and locking the seat (200) with the body of the vehicle. In an illustrative embodiment, two latches (15) have been depicted in Fig. 1, each of which are disposed on either sides of the frame (20) to lock the frame (20) with the body of the vehicle. However, this should not be construed as a limitation as the seat (200) may include less than or more than two latches (15) to selectively lock and unlock the seat (200).
Referring now to Figs. 2 and 3, the seat (200) of the vehicle may include a mechanism (100) for unlocking the seat (200). In an illustrated embodiment, the mechanism (100) is described

with respect to backrest of the seat (200). However, the same cannot be construed as a limitation since the mechanism (100) may be employed for unlocking the base portion (14) of the seat (200) as well. The mechanism (100) may include a primary plate (1) which may be pivotally connected to a primary base unit (3). The primary base unit (3) may be rigidly disposed on the frame (20) of the seat (200). The primary base unit (3) may be adapted to support the primary plate (1), such that components of the frame (20) do not come in contact with the primary plate (1). The primary plate may be configured to pivot between a first condition (FC) [as seen in Fig. 4a] and a second condition (SC) [as seen in Fig. 4b] from an intermediate condition (IC) [as seen in Fig. 2]. Further, the mechanism (100) may include a lever (8) which may be coupled to the primary plate (1). Furthermore, the mechanism (100) may include a plurality of connection members (5) for connecting the movable components with each other. In an embodiment, the plurality of connection members (5) may include a plurality of sets of connection members (5), namely a first set of connection members (5a), a second set of connection members (5b) and a third set of connection members (5c). The primary plate (1) may be coupled to the lever (8) through the first set of connection members (5a). In an embodiment, the lever (8) may be adapted to pivotally displace the primary plate (1) corresponding to actuation of the lever (8) by an operator. In an embodiment, the first set of connection members (5a) may be adapted to displace towards the lever (8) upon actuation of the lever (8) to pivotally displace the primary plate (1). In an embodiment, the primary plate (1) may be defined with a protrusion (13) which may extend from a portion of the primary plate (1). The protrusion (13) may be adapted to receive the first set of connection members (5a) from the lever (8). The protrusion (13) may extend from the portion of the primary plate (1) such that displacement of the first set of connection members (5a) exerted upon the protrusion (13) may exert a lateral pulling force on the protrusion (13). The lateral pulling force on the protrusion (13) may convert to a pivotal motion due to the pivotal connection of the primary plate (1). That is, upon the operator actuating the lever (8), the connection members (5) may be adapted to relatively displace the primary plate (1) in the pivotal direction. For example, as seen in Figs. 4a and 4b, upon actuation of the lever (8), the primary plate (1) may be adapted to either pivot in a clock wise direction that is from the intermediate condition (IC) to the first condition (FC) or an anti-clock wise direction that is from the intermediate condition (IC) to the second condition (SC). In one embodiment, the lever (8) may be a mechanical lever, which may be adapted to receive a mechanical displacement by the operator which may be then transferred to the primary plate (1) for pivotal displacement. In another embodiment, the primary plate (1) may be coupled with an actuator which may be configured to pivotally

displace the primary plate (1). The actuator may be communicatively coupled to lever (8) and may be configured to pivotally displace the primary plate (1) corresponding to actuation of the lever (8). The lever (8), for operating the actuator may act as a switch which may transmit electrical signals. In an embodiment, the actuator may a rotary actuator which may be adapted to operate by electrical means or pneumatic means or hydraulic means.
In an embodiment, the lever (8) may be position at any location within the cabin of the vehicle, for example, the lever (8) may be positioned under the dashboard, at any location proximal to the driver seat, next to the rear seat, in the trunk of the vehicle and any other location easily accessible to the operator. Additionally, as seen in Fig. 2, two levers (8) have been illustrated for operating the mechanism (100). However, the number of levers (8) should not be construed as a limitation as one or more than one lever (8) may be positioned at any location of the vehicle to operate the mechanism (100) for unlocking the seat (200) [thus, unlocking the backrest of the seat (200)]. In an embodiment, the lever (8) may be in forms of operational components such as but not limited to a pivot lever, a spring loaded button, a rotary knob, a strap, a handle, electronic switch and the like.
Furthermore, as seen in Figs. 2 and 3, the mechanism (100) may include a pair of secondary plates (2). Each of the pair of secondary plates (2) may be slidably coupled on either sides of the primary plate (1). Further, the pair of secondary plates (2) may be slidably disposed on a secondary base unit (4) which may be rigidly disposed on the frame (20) of the seat (200). In an embodiment, the secondary base unit (4) may be defined with plurality of provisions (12) which may aid in sliding motion of the pair of secondary plates (2). For example, the plurality of provisions (12) defined on the secondary base unit (4) may be including but not limited to rails, grooves, projections, key ways and the like. Each of the pair of secondary plates (2) may be connected to the at least one latch (15). The pair of secondary plates (2) may be connected to the at least one latch (15) through the third set of connection members (5c). In an embodiment, displacement of the pair of secondary plates (2) may be adapted to operate the at least one latch (15) to unlock the seat (200) in the vehicle.
Referring to Fig. 2, the pair of secondary plates (2) may be connected to the primary plate (1) through the second set of connection members (5b). In an illustrated embodiment, two connection members (5b) of the second set of connection members (5b) are connected between the primary plate (1) and each of the secondary plate (2). Further, the second set of connection members (5b) may be adapted to transfer pivotal displacement of the primary plate (1) onto

each of the pair of secondary plates (2) for sliding. In an embodiment, the pair of secondary plates (2) may be configured to displace between a first position (FP) and a second position (SP) corresponding to pivotal displacement of the primary plate (1). The first position (FP) may be a position of the pair of secondary plates (2) on the secondary base unit (4) away from the primary plate (1). Further, the second position (SP) may be the position of the pair of secondary plates (2) on the secondary base unit (4) towards or closer to the primary plate (1). In an embodiment, the pivotal displacement of the primary plate (1) due to actuation of the lever (8) may be configured to slide the pair of secondary plates (2) from the first position (FP) to the second position (SP). In an embodiment, the first position (FP) of the pair of secondary plates (2) may correspond to a locked condition of the at least one latch (15) and the second position (SP) of the pair of secondary plates (2) may correspond to an unlocked condition of the at least one latch (15).
Referring further to Figs. 2 and 3, the pair of secondary plates (2) may be defined with a pair of slots (9). Each of the pair of slots (9) may be adapted to movably receive an end of the second set of connection members (5b) to slidably connect the pair of secondary plates (2) with the primary plate (1). In an embodiment, the pair of slots (9) may be configured to allow displacement of the end of the plurality of connection members (5) in the pair of secondary plates (2). In an embodiment, the pair of slots (9) may include a first slot (9a) and a second slot (9a) which may be defined with an elongated profile. Further, the third set of connection members (5c) may be connected at an end of the pair of secondary plates (2) for connecting the pair of secondary plates (2) and the at least one latch (15).
In an embodiment, the plurality of connection members (5) may be including but not limited to bowden cables, rods, wires and the like, which may be flexible and/or rigid capable of transferring displacement.
In an embodiment, the mechanism (100) may include at least one first resilient member (6) coupled and extending between the primary plate (1) and a primary base unit (3) to bias the primary plate (1) at the intermediate condition (IC) between the first condition (FC) and the second condition (SC). The intermediate condition (IC) of the primary plate (1) may be the condition of the primary plate (1) when the lever (8) is in the de-actuated state. That is the at least one first resilient member (6) may be adapted to pivotally displace the primary plate (1) back to the intermediate condition (IC) from a pivoted condition upon de-actuation of the lever (8). Further, the displacement of the primary plate (1) from the pivoted condition to the

intermediate condition (IC) may result in displacement of the pair of secondary plates (2) from the second position (SP) to the first position (FP) due to connection between the primary plate (1) and the secondary plate (2).
In an embodiment, at least one second resilient member (7) may be connected between each of the pair of secondary plates (2) and the secondary base unit (4). The at least one second resilient member (7) may be configured to bias the pair of secondary plates (2) towards the first position (FP). That is the at least one second resilient member (7) may be adapted to slidably displace the pair of secondary plates (2) back to the first position from the second position upon de-actuation of the lever (8) or displacement of the primary plate (1) back to the intermediate condition (IC). In an embodiment, the at least one first resilient member (6) and the at least one second resilient member (7) are springs.
In an embodiment, the mechanism (100) may include a primary cover (10) which may be adapted to enclose the primary plate (1) over the primary base unit (3). Further, the mechanism (100) may include a secondary cover (11) to enclose the pair of secondary plates (2) over the secondary base unit (4). The primary cover (10) and the secondary cover (11) may be adapted to protect the primary plate (1) and the pair of secondary plates (2) from other components of the seat (200) and allow displacement without obstruction.
In an operational embodiment, a rear seat (200) backrest is equipped with the mechanism (100) for unlocking the backrest such that the back rest may be folded to increase the trunk or boot portion space in the vehicle. For illustrative purpose as seen in Fig. 4a, the lever (8) may be positioned adjacent to each side of the seat (200) in the vehicle. For the sake of simplicity, unlocking of the seat (200) by actuating the lever (8) position on the left side of the seat (200) is detailed. The operator upon actuating the lever (8) [positioned on the left side of the seat (200)], the first set of connection members (5a) of the plurality of connection members (5) connected between the lever (8) and the primary plate (1), may displace the primary plate (1) in the from the intermediate condition (IC) to the first condition (FC) (clock wise direction).
The pivotal displacement of the primary plate (1) from the intermediate condition (IC) to the first condition (FC) may result in increase in distance between the top left corner of the primary plate (1) and the secondary plate (2) positioned on the left of the primary plate (1). The increase in distance between the primary plate (1) and the secondary plate (2) [on the left] results in displacement of the secondary plate (2) towards the primary plate (1) due to the connection

through the second set of connection members (5b). That is, the secondary plate (2) [on the left] is slidably displaced from the first position (FP) to the second position (SP). Further, the pivotal displacement of the primary plate (1) to the first condition (FC) may result in decrease in distance between the bottom left corner of the primary plate (1) and the secondary plate (2) positioned on the left of the primary plate (1). The decrease in distance between the primary plate (1) and the secondary plate (2) [on the left] results in displacement of an end of one of the second set of connection members (5b) in one of the pair of slots (9) in the secondary plate (2). That is, the decrease in distance at the bottom left corner of the primary plate (1) does not affect the sliding displacement of the secondary plate (2) [on the left] from the first position (FP) to the second position (SP).
Further, the pivotal displacement of the primary plate (1) from the intermediate condition (IC) to the first condition (FC) may result in increase in distance between the bottom right corner of the primary plate (1) and the secondary plate (2) positioned on the right of the primary plate (1). The increase in distance between the primary plate (1) and the secondary plate (2) [on the right] results in displacement of the secondary plate (2) towards the primary plate (1) due to the connection through the second set of connection member (5b). That is, the secondary plate (2) [on the right] is slidably displaced from the first position (FP) to the second position (SP). Further, the pivotal displacement of the primary plate (1) to the first condition (FC) may result in decrease in distance between the top right corner of the primary plate (1) and the secondary plate (2) positioned on the right of the primary plate (1). The decrease in distance between the primary plate (1) and the secondary plate (2) [on the right] results in displacement of the end of one connection member (5b) of the second set of connection members (5b) in one of the pair of slots (9) in the secondary plate (2). That is, the decrease in distance at the top right corner of the primary plate (1) does not affect the sliding displacement of the secondary plate (2) [on the right] from the first position (FP) to the second position (SP).
This way, by actuating a single lever (8), both the pair of secondary plates (2) may be displaced from the first position (FP) to the second position (SP), which in-turn operates the at least one latch (15) from the locked condition to the unlocked condition to unlock the seat (200). Furthermore, upon the operator de-actuating the lever (8), the primary plate (1) and the pair of secondary plates (2) may return back to the intermediate condition (IC) and the first position (FP), respectively, due to the biasing force of the at least one first resilient member (6) and/or the at least one second resilient member (7).

In an embodiment, the mechanism (100) is simple in construction and easy to operate. Additionally, due to simple construction and less number of components, requirement for frequent maintenance is eliminated and costs involved in manufacturing are reduced.
In an embodiment, the mechanism (100) enables one touch operation by the operator to unlock the seat (200), which eliminates cumbersome requirements of the conventional systems to unlock the seat (200).
In an embodiment, the lever (8) may be located at any location within the cabin of the vehicle for easy access for the operator or the driver.
It should be imperative that the mechanism and any other elements described in the above detailed description should not be considered as a limitation with respect to the figures. Rather, variation to such system and method should be considered within the scope of the detailed description.
Equivalents:
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at

least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope.
