Abstract
Abstract A rear vehicle seat assembly comprises a seat cushion member supported by a support sub-assembly having downwardly extending front and rear seat legs. Each front seat leg includes a forked leg member co-operable with an attachment rod on a vehicle floor. Each rear seat leg includes a forked leg portion co-operable with a attachment rod on the vehicle floor. A first moveable lock member mounted on each of the rear seat legs permits selective locking of the respective one of the rear seat legs on the corresponding attachment rod. A biasing spring urges each lock member to a locked position. A manually operable handle is mounted on each of said rear seat legs to provide for selective manipulation of each lock member into an unlocked position, in order to release the rear seat legs with respect to the corresponding attachment rod, thereby to allow the vehicle seat assembly to be pivotal about the attachment rods associated with the front seat legs, between a lowered position and an uptilted position. A control rod system pivotally connected to the vehicle seat assembly is selectively moveable between a stowed position whereat the control rod system is retracted adjacent the underside of the seat cushion member, and a deployed support position whereat the control rod system is situated in stable, interposed relation between the underside of the seat cushion member and the vehicle floor when the vehicle seat assembly is in the uptilted position, so as to support the seat assembly in the uptilted position.
