A shock absorption in a seat back of a seat, which is arranged in a bracket fixed on the seat back frame in the seat back and an operation lever attached to the bracket. In this arrangement, the bracket is formed such that upper and lateral wall regions are defined independently of each other, with a slit defined therebetween. The lower securing portion of the bracket, fixedly secured on the seat back frame, is relatively easy to bend forwardly relative to the seat back frame by an external load applied to the rearward side thereof. A stopper wire member, which has an abutment end portion, is provided over the vertical wall region of bracket and a part of the seat back frame, such that the abutment end portion is oriented toward the operation lever. Hence, the bracket is bendable forwardly by a great external load applied from the rear side of seat back frame, in which case, the operation lever in the bracket will be abutted against the abutment end portion of stopper wire member, causing both bracket and stopper wire member to bend forwardly, to thereby absorb a corresponding great shock.

A structure of seat cushion frame in a vehicle seat, which has a pair of upwardly projected side frames, one of them being disposed at the side of a door of the vehicle, wherein such one of the side frames is formed with a cut-away portion at the rearward are thereof, with a forward side frame being thus defined therein, and wherein an expandable member is extended between the cut-away portion and forward side frame. The expandable member acts to allow vertical flexture of the corresponding lateral bolster portion of seat cushion, after upholstering the seat cushion frame to form the seat cushion, so that a passenger can descend from or climb onto the seat with a comfortable touch.

A head-rest is disclosed in which the lower ends of the stays are fixed to a seat frame of a seat back and a head-rest body is mounted to these stays in a manner that it is free to move in a vertical direction so as to provide a deeper recessed cavity in the rear of the seat back.

Head-rest

A seat for vehicles is provided with a reclining device and a remote control means for remotely controlling the reclining device, in which seat an arm rest is pivotally mounted and provided at its forward end portion with the remote control means and at its upper portion with a recessed portion for receipt of one or more small articles. The arm rest has a linking mechanism arranged therewithin for mechanically linking the remote control means to the reclining device. The linking mechanism comprises a rod connected to the remote control means, a substantially V-shaped arm having a first leg portion and a second leg portion, of which leg portions the first leg portion is connected with the rod, an operation wire connected to the second leg portion of the substantially V-shaped arm and further connected to the reclining device and a spring extended between the first leg portion of the arm and the inner wall of the arm rest.

Seat for vehicles

A head-rest vertical adjustment device is disclosed which is provided with a lock mechanism to restrict the vertical movements of a head-rest stay in a guide cylinder into which the head-rest stay is inserted in a manner that it is free to move vertically. This lock mechanism comprises a lock spring of a wire material to be engaged into an engagement groove formed in the head-rest stay from a slit formed in the guide cylinder, and an operation lever to release the lock spring from its locked position. First ends of both the lock spring and operation lever are rotatably mounted onto the same projection provided in the guide cylinder and second ends of these two members are integrally connected to each other.
