<p>A vehicle seat (10) includes a seat cushion assembly (12) for supporting an occupant seated thereon and a seat back cushion assembly (14) for supporting the back of an occupant seated on the seat cushion assembly (12). A first mounting assembly (18) is constructed and arranged to mount the seat cushion assembly (12) on a vehicle floor (20) and a second mounting assembly (13) is provided which is constructed and arranged to mount the seat back cushion assembly (14) on the seat cushion assembly (12). An adjusting mechanism (28) is operatively embodied in one of the first and second mounting assemblies (18, 13) and is constructed and arranged to enable the cushion assembly (12, 14) mounted by the one mounting assembly (18, 13) to be moved in opposite directions through a range of adjustable positions with respect to the assembly on which the one mounting assembly mounts the cushion assembly. The adjusting mechanism includes a locking and releasing device (42) constructed and arranged to be moved between (A) a locking position to lock the adjusting mechanism (28) to prevent movement in either direction of the cushion assembly (12, 14) enabled to be moved thereby, and (B) a releasing position to release the adjusting mechanism (28) to permit the cushion assembly (12, 14) enabled to be moved thereby to be manually moved in relatively unrestricted fashion in one direction and returned in relatively unrestricted fashion in the opposite direction. A vehicle crash sensing system (62) is operatively connected with the adjusting mechanism (28) and is constructed and arranged to provide control of the movement of the cushion assembly (12, 14) mounted by the one mounting assembly in response to the sensing of a crash condition which occurs while said locking device (42) is in the releasing position.</p> |
