TECHNICAL FIELD:
The subject matter described herein, in genera!, relates to a seat and in particular relates to a slouch seat for a vehicle. BACKGROUND:
Conventional, vehicles have different types of seats such as a front seat, a rear seat, a bench seat, a split seat, a slouch seat and so on. The seats of a vehicle have a seat backrest and a cushion seat.
A slouch seat is a seat in which seat back and seat bottom move in conjunction with each other. This is so because the seat back and seat bottom are connected to each other in such a manner that when the seat back is displaced, the seat bottom is automatically adjusted according to the new position of the seat back.
Typically, the seat back slides with reference to a notional plane. It is desirable to provide a structure that defines the plane along which the seat back can slide.
Further, it is desirable to efficiently use the passenger cabin space of a vehicle. At the same time, it is also necessary to provide comfort to the passenger. SUMMARY:
l"he subject matter described herein is directed to a vehicle slouch seat. According to atleast one aspect of the presenl subject matter the vehicle slouch seat includes a cushion frame, a backrest frame pivotally connected to the cushion frame, a stationary member attached to the passenger cabin and a locking assembly mounted on the backrest frame. The locking assembly further includes a bracket having a cavity. The cavity is adapted to receive the stationary member. A resilient member selectively allows the

stationary member lo enter the cavity. The stationary member guides the motion of the bracket, thereby allowing adjustment of the vehicle slouch seat.
The adjustment of the slouch seat adds to the passengers' comfort by allowing him to recline the backrest to a desirable position, thereby automatically adjusting the cushion frame. Moreover, the locking assembly attached to the backrest allows the passenger to lock the seat in the desirable position.
These and other features, asp)ects, and advantages of the present subject matter will be better understood with reference to the following description and appended claims. This surmnary is provided to introduce a selection of concepts in a simplified form. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

DETAILED DESCRIPTION:
The subject matter described herein is directed to a slouch seat for a vehicle. According to atleast one aspect of the present subject matter the slouch seat includes a cushion frame and a backrest frame pivotally connected to the cushion frame. Further, a stationary member fixed to the vehicle body is provided in the passenger cabin of the vehicle and a locking assembly is mounted on the backrest frame. Optionally, a headrest is attached to the backrest frame of the seat.
The slouch seat is further provided with a locking assembly. The locking assembly includes an L-shaped bracket having a linear cavity and a resilient member. The cavity is adapted to receive the stationary member. The resilient member, in an extended position, selectively allows the stationary member to enter the cavity. The resilient member allows entry into and disallows exit, of the stationary member from the cavity, while in the extended position. The resilient member allows exit of the stationary member from the cavity, while in a retracted position. Upholstery covers the cushion frame and the backrest frame. The stationary member guides the motion of the bracket, thereby allowing limited adjustment of the seat,
Fig.lA shows a perspective view of a vehicle slouch seat 100. The seat 100 includes a cushion frame 102 and a backrest frame 104. The locking assembly 106 is mounted on the backrest frame 104 and engages with the striker rod assembly 308 to firmly secure the backrest frame 104 to the vehicle body. The cushion frame 102 and the backrest frame 104 are connected to each other by means of a pivot 110 and the cushion frame 102 is capable of moving horizontally.

Fig.IB shows an isolated view of the locking assembly 106 and the striker rod assembly 108. The locking assembly 106 and the striker rod assembly 102 are shown in engaged condition.
Fig.2A, Fig.2B and Fig.2C are schematic views of the locking assembly 106 from various perspectives. The locking assembly 106 includes an L-shaped bracket 202 having a front wall 204 and a side wall 206, The front wall 204 is attached to the backrest frame 104 of the seat 100. The side wall 206 has a vertical slot 208, interchangeably referred to as "cavity", and a horizontal slot 210. Entry to the vertical slot 208 is controlled by a lock cam 212, which is disposed in the horizontal slot 210. The lock cam 212, interchangeably referred to as "resilient member", has a wedge shape and is fixed to the side wall 206 by means of a cam rivet 214. The cam rivet 214 can move in a vertical opening 216, so as to allow the lock cam 212 to slide up and dovm. The motion of the lock cam 212 is further governed by a lever 218, which is provided for unlocking the backrest frame 104 of the seat 100. A stopper pin 220 is fixed onto the side wall 206 and is provided to restrict the downward motion of the lock cam 212, The stopper pin 220 also provides support to the lock cam 212, resulting in an increased load bearing capacity. A plate 222, attached to the side wall 206 by means of fasteners 224, covers an intemal mechanism. The internal mechanism includes a support cam 226, which is pivoted about a shaft 228, A spring 230 keeps the support cam 226 under tension and forces the lock cam 212 to remain in the locked position. A washer 232 is used to secure the cam rivet 214 to the side wall 206. Fig.3 is a perspective view of the striker rod assembly 108. The striker rod assembly 108 includes a striker rod 302 and holding brackets 304 and 306. The striker rod 302 is

interchangeably referred to as ''stationary member". Holding brackets 304 and 306 are mounted on the vehicle structure i.e. the body of the vehicle.
When the backrest frame 104 of the seat 100 is in unlocked position, the backrest frame 104 can move pivotally about the pivot 110. To secure the backrest frame 104 to the structure of the vehicle, the backrest frame 104 is pulled backwards. The striker rod 302 enters the horizontal slot 210 and strikes the lock cam 212. The lock cam 212, because of its wedge shape, slides upwards and allows the striker rod 302 to enter the vertical slot 208. When the striker rod 302 reaches the vertical slot 208, the spring 230 forces the lock cam 212 to slide downwards and come to its initial position. The striker rod 302 is prevented from coming out of the vertical slot 208 on its own because of the shape of the lock cam 212.
When the backrest frame 104 is to be unlocked, the lever 218 is pulled upwards, thereby allowing passage to the striker rod 302. TTie striker rod 302 moves out from the vertical slot 208 through the horizontal slot 210, and the seat 100 is unlocked. When the seat 100 is to be repositioned, the striker rod 302 in the vertical slot 208 guides the motion of the bracket 202. The striker rod 302 can move from the uppermost end to the lowermost end of the vertical slot 208. When the backrest frame 104 is adjusted, the cushion frame 102 moves in the horizontal direction. The seat 100 is in upright position when the striker rod 302 is at the uppermost end of the vertical slot 208, while for other positions of the striker rod 302 inside the vertical slot 208, the seat 100 is in slouch position. The backrest frame 104 can be adjusted so that the striker rod 302 attains an infinite number of positions in the vertical slot 208, thereby adjusting the position of the seal 100.

The previously described versions of the subject matter and its equivalents thereof have many advantages, including those which are described below. The lock cam 212, being resilient one, comes down on its own.
Although the subject matter has been described in considerable detail with reference to certain preferred embodiments thereof, other embodiments are possible. As such, the spirit and scope of the appended claims should not be limited to the description of the preferred embodiment contained therein.
