Vehicle seat with cushion plate

A vehicle seat is provided comprising: a seat back frame having a side frame; a headrest for supporting a head of a seat occupant; a load receiving member disposed behind the seat occupant and movable rearward in response to a load from the seat occupant; and a link member mounted to the seat back frame and rearwardly movable; wherein: a rearward movement of the load receiving member moves the link member rearward and reduces a distance between the head of the seat occupant and the headrest; the load receiving member is provided with a first through-hole and a second through-hole; and the first through-hole and the second through-hole are disposed in a same horizontal plane.

A vehicle seat includes a reclining mechanism having a lock member, which is engaged with a ring member when it is pressed by a cam body, and a walk-in mechanism. A rotating arm, which is rotated by operation of a reclining lever or a walk-in lever, is secured to a center shaft. The reclining lever operates the rotation of the rotating arm by a link lever having a slot. The walk-in lever operates the rotation of the rotating arm independently of the reclining lever. When a seatback is tilted forward by the operation of the walk-in lever, the slide mechanism of the vehicle seat is unlocked, and the entire seat is moved forward.

Vehicle seat

A vehicle seat comprises a rectangular-shaped seat back frame having right and left side frames; a headrest for supporting a head of a seat occupant that is installed within the vehicle seat; a rear-end collision detector mounted to the seat back frame at a position behind the seat occupant, wherein the rear-end collision detector detects rearward movement of the seat occupant and moves rearward; a link member that supports the rear-end collision detector with the seat back frame therethrough; and a biasing member that biases the link member; wherein: the rear-end collision detector acts such that the rearward movement of the rear-end collision detector reduces a distance between a head of the seat occupant and the headrest, and a lower end portion of the biasing member is coupled to a rear portion of the side frame and disposed posterior to the rear-end collision detector.

A latch assemblyincludes a base platehaving a striker groove, a latchprovided in the base plateand having a striker engaging groove, and a ratchetfor regulating rotation of the latchin unlatch direction. A looseness eliminating leveris attached to the latchby means of a pinmoving around a latch shaft, one end of the looseness eliminating leveris provided with a latch holding faceand an unlatch faceto contact with a postprovided at a specified position, the other end of the leveris provided with a springfor biasing the guide faceor the sliding faceto be always in contact with the post, and an apexas a dead center is formed between the guide faceand the sliding face. The guide faceis formed in an arc-shaped inclined surface so as to be remoter from the pinfrom a start end to a terminal end.

Latch device for vehicle seat

A vehicle seat comprises a rectangular-shaped seat back frame having right and left side frames; a flexible plate member provided between the right and left side frames; a seat back cushion provided in front of the flexible plate member; a mechanism for pushing the seat back cushion to a front direction by forwardly protruding the flexible plate member that results from the flexible plate member being bent; a headrest for supporting a head of a seat occupant, wherein the headrest is forwardly movably connected to the right and left side frames via right and left link members; and a rear-end collision detecting plate disposed at a portion of the seat back frame behind the seat occupant, wherein the rear-end collision detecting plate detects rearward movement of the seat occupant.

A vehicle seat comprises a seat back frame having a pair of side frames, a seat spring mounted between the side frames, a single plate-shaped flexible cushion plate mounted to the seat spring, a seat back cushion provided in front of the cushion plate, a single plate-shaped flexible auxiliary plate mounted on the cushion plate. The auxiliary plate is located between the cushion plate and the seat back cushion. The auxiliary plate pushes the seat back cushion to the front by being forwardly bent in response to an operation member. A collision detector is located on the rear side of the cushion plate having a predetermined distance therebetween.
