ABSTRACT:
An automotive seat assembly for accommodating rear passengers in a passenger compartment. The seat assembly includes a base that may be secured to the vehicle floor structure and an articulated seat frame that supports a lower seat portion, a back portion of the seat assembly being foldable forward. The articulated frame includes forward and rearward legs, one leg being biased by a spring toward a normal passenger supporting position and the other leg being biased by a spring towards a folded position of the seat assembly. The spring force acting on one leg acts on a variable moment arm so that the force moment created by the spring force on the other leg is opposed, the seat assembly assuming a folded position as an over center position of the forward arm is reached, the variable moment arm of the spring force acting on the one arm maintaining the legs in a normal upright position when the seat assembly is in use.
