Abstract

A slidable front seat for a motor vehicle which slides forwardly when the seat back is pivoted forwardly. The seat back frame has an inverted U-shape and its ends are articulated to a pair of parallel guides on the automobile body floor. Two levers are pivoted between the back frame and two guides, fixed to the seat frame, slidable forwardly and backwardly in the parallel guides. As the seat back is tilted forwardly about the articulation axis, the levers slide the seat forwardly. A pin locks the relatively slidable guides together, the pin being manually movable out of locking position to permit the seat to slide. One of each pair of relatively slidable guides carries a tooth which engages the other guide to limit rearward movement of the seat. The tooth is accommodated within a slot in the other guide, when the seat is in its position of use, to prevent transverse movement of the seat.

Claims

1. A motor vehicle seat, comprising

(a) a seat frame carrying two parallel upper guides,

(b) two parallel lower guides adapted to be fixed to a vehicle floor,

(c) two parallel intermediate guides interconnecting said upper and lower guides, respectively, each intermediate guide being slidable longitudinally with respect to its respective upper and lower guides,

(d) a seat back frame pivotally secured to said intermediate guides for pivotal movement about an axis perpendicular to the longitudinal direction of movement of said intermediate and upper guides, and

(e) a lever pivotally connected between said seat back frame and each of said upper guides,

whereby forward pivotal movement of said seat back frame causes said seat frame and upper guides to move forwardly with respect to said intermediate guides, and said seat and back frame can be moved bodily forwardly and backwardly by moving said intermediate guides longitudinally with respect to said lower guides.

2. A motor vehicle seat as defined in claim 1 including a latch movably mounted on one of said intermediate guides, an opening in the respective one of said upper guides for receiving said latch to lock the two guides together against relative movement, and resilient means urging said latch into said opening.

3. A motor vehicle seat as defined in claim 1 including a tooth projecting laterally from each upper guide, and a slot in each intermediate guide for slidably accommodating its respective tooth when said seat back frame is in its normal rearward position, said teeth sliding out of said slots when said seat back frame is pivoted forwardly to move said upper guides with respect to said intermediate guides.
