Abstract

Abstract A vehicle seat is provided which can be conveniently stowed when not in use. The vehicle seat includes a seat bottom mounted for pivotal movement relative to the vehicle floor and a seat back mounted for pivotal movement relative to the seat bottom. To stow the seat, the seat back is folded onto the seat bottom which is then pivoted to the stowed position. When the seat bottom is in its seat forming position a first latch secures it to the vehicle floor; a second latch secures the seat back relative to the seat bottom when the seat back is in its seat forming position. An interlock between the first and second latches obviates latching by the second latch until and unless the first latch has been latched. This sequential latching insures that the seat bottom is secured to the vehicle floor at all times during which the seat back is latched in its seat forming position.
