ABSTRACT:
The seat cushion of a bench type vehicle seat has a first end pivotally mounted on the vehicle body and a second end mounted by a track assembly permitting fore and aft sliding movement of the second end so that the entire seat swivels about the first end. A link is located adjacent the second end of the seat cushion and has a lower end pivoted to the vehicle floor. A seat back has one end pivotally connected to the first end of the seat cushion and another end pivotally connected to the link. The link has a cam slot in which a cam roller mounted on the seat cushion is slidably engaged so that pivotal movement of the link effects fore and aft sliding movement of the second end of the seat cushion. A first latch is provided between the link and the seat. A second latch is provided between the seat back and the vehicle body. When the second latch is released the seat back and link are permitted to pivot forwardly which in turn induces forward swiveling movement of the seat cushion to facilitate access behind the seat. A lost motion connecting linkage is provided between the first and second latches so that unlatching of the first latch effects simultaneous unlatching of the second latch to permit pivotal movement of the seat back relative the seat cushion and the link to thereby move the seat back to a cargo floor forming position overlying the seat cushion.
