BACKGROUND
[002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.
[003] The vehicles, for example two-wheeled vehicles, are provided with a seat to provide seating space for a driver and a passenger. Now-a-days, the two-wheeled vehicles are provided with split seat arrangement to enhance aesthetic of the vehicle and to increase comfort for the driver and the passenger. The split seat arrangement comprises of a driver seat and a passenger seat mounted on seat rails of the vehicle, such that the driver seat and the passenger seat are mounted at separately on the seat rails and are not in contact with one another.
[004] The split seat arrangement utilizes more number of components to facilitate mounting of the seats on to the seat rail of the vehicle. In addition to that, in the split seat arrangement, each of the driver seat and the passenger seat is provided with a dedicated seat locking mechanism to facilitate opening of the driver seat and the passenger seat. The seat locking mechanism for the driver seat facilitates opening of the driver seat to access components of the vehicle mounted below the driver seat. Similarly, a separate seat locking mechanism is provided for the passenger seat to facilitate opening of the passenger seat to have access of a storage compartment disposed below the passenger seat.
[005] The utilization of dedicated locking mechanism for the driver seat and the passenger seat occupies more packaging space of the vehicle and thereby increases complexity for mounting other peripheral components of the vehicle. In addition to that, the dedicated locking mechanism for the driver seat and the passenger seat increases the components of the vehicle, which in turn increases the over all cost of the vehicle including - manufacturing cost of the vehicle, assembling cost of the vehicle as well as maintenance cost of the vehicle. Each dedicated lock mechanism is required to be actuated by a user in a separate manner to facilitate opening of the driver seat and the

passenger seat. The actuation of individual lock mechanism by the user separately increases efforts and reduces comfort of the user. Therefore, the provision of utilizing two locking mechanism for locking/unlocking the driver seat and the passenger seat of the vehicle, increases the efforts for unlocking said seats, i.e. the driver seat and the passenger seat of the vehicle.
[006] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the existing seat lock systems of the vehicle.

The first grommet (23 e) prevents unintentional movement of the cable (23),

while driving the vehicle. The cable (23) is attached with a first notch (23c), preferably the first notch (23c) is attached at a first end of the inner wire (23a) of the cable (23).
[068] In an exemplary embodiment, the latch mechanism (11) and its sub-components are shown in Figures 8-10. The latch mechanism (11) comprises a top plate (11a), a guide plate (lib) and a bottom plate (lie). The bottom plate (lie) comprises a first flange (lid) configured to hold the outer sheath (23b) of the cable (23). The guide plate (1 lb) is defined having a cutout (1 lh) to receive a lever (1 If). The lever (1 If) comprises a movable second flange (lie) extending from one end of the lever (1 If). The lever (1 If) is pivotably connected to the top plate (11a) and the bottom plate (lie) by means of a pivot pin (llg). The second flange (lie) is configured to receive a second notch (23d) provided at a second end of the inner wire (23a) of the cable (23). The latch mechanism (11) further comprises a spring (12) received at the second end of the inner wire (23a) and is positioned between the two flanges (lid, lie), such that the spring (12) is configured to bias the lever (1 If) in a locked position. The locking pin (13) fixed to the bottom panel (10a) of the first seat (10) to facilitate locking of the first seat (10) with the lever (1 If). The first flange (lid) has a cutout adapted to receive a second grommet (23f) to facilitate rigid connection between the outer sheath (23b) of the cable (23) and the first flange (lid). The second grommet (23f) may be defined as a rubber grommet. The top plate (11a), the guide plate (lib) and the bottom plate (lie) are connected to one another by conventional connecting means, for example - rivets, fasteners, clamps, snap-locks and likewise. In an exemplary embodiment, the top plate (11a), the guide plate (1 lb) and the bottom plate (lie) are connected to one another by at least two rivets (Hi), as shown in Figure 10. Once again referring to Figure 8, the latch mechanism (11) is mounted on athird flange (14) of the frame (212) of the vehicle. The latch mechanism (11) is mounted on the third flange (14) by plurality of fasteners (15).
[069] Referring to Figures 11 a-lie, multiple positions of the second seat (20) of the vehicle is depicted while opening the second seat (20) and the first seat (10) of the vehicle. Referring to Figure 11a, the first seat (10) and the second seat (20) is shown in a closed position. The closed position of the first seat (10) is defined as a position in which the locking pin (13) of the first seat (10) is engaged with the lever (1 If) of the latch mechanism (11). The closed position of the second seat (20) is defined as a

position in which the second seat (20) rests on the seat plate (30). In the closed position of the second seat (20), a length "L" of the inner wire (23a) of the cable (23) is provided over-hanging beyond the slider (21), as shown in Figure 11a. The length "L" of the inner wire is a distance between the slider (21) and the first notch (23c) of the cable (23), when the second seat (20) is in the closed position. The length "L" provides the user to facilitate opening of the second seat (20) only without actuating the latch mechanism (11) of the first seat (10).
[070] Referring to Figure lib, the latch mechanism (11) is actuated once the user applies an upward force on the second seat (20) to facilitate pivotal movement of the second seat (20) beyond a predefined angle or position to an actuated position. The pivotal movement of the second seat (20) beyond the predefined angle or position facilitates abutting action of the first notch (23c) with the slider (21). The pivotal movement of the second seat (20) then governs sliding movement of the slider (21) along the slot (31) and towards the rear end of the seat plate (30). The sliding movement of the slider (21) along the slot (31) actuates the latch mechanism (11), once the slider (21) covers a distance greater than the length "L" of the inner wire (23a). The sliding movement of the slider (21) towards the rear end applies pulling force on the inner wire (23a) of the cable (23), which in turn pulls the lever (1 If) mounted on the latch mechanism (11) of the first seat. The pulling of lever (1 If) facilitates pivotal movement of lever (1 If) about the pivot pin (1 lg) and which in turn results in dis engagement of the lever (1 If) from the locking pin (13) of the first seat (10). The disengagement of the lever (1 If) from the locking pin (13) facilitates unlocking of the first seat (10) and the user can open the first seat (10). The actuated position of the second seat (20) is defined as a position at which the lever (1 If) disengages with the locking pin (13) of the first seat (10), as shown in Figure lie. The pivotal movement beyond the actuated position of the second seat (20) is restricted once the lever (1 If) disengages from the locking pin (13) of the latch mechanism (11) mounted on the first seat (10).
[071] In an exemplary embodiment of the present disclosure, a method for operating a seat lock system (100) for a vehicle is disclosed. The method comprises: unlocking a second seat (20) by operation of a key inserted in a keyhole (25) provided on the second seat (20). The next step is to apply an upward force on the second seat (20) to pivotally

move the second seat (20) about an axis X-X beyond a predefined angle to actuate a latch mechanism (11) to facilitate unlocking of a first seat (10).
[072] In an embodiment of the present disclosure, the seat lock system provides a simple system to unlock the rider seat by opening of the pinion seat.
[073] In an embodiment of the present disclosure, the system reduces number of components to unlock the rider seat when compared to existing solutions for unlocking the rider seat.
[074] In an embodiment of the present disclosure, the system reduces overall cost of the vehicle by reducing number of components in the vehicle.
