ABSTRACT:
A hinge mechanism for a vehicle seat assembly is disclosed which includes a leaf spring on the seat back arm of the hinge with one end extending from the seat back arm and engaging the edge of a plate member across which the spring and slides as the seat back is rotated from its upright operative position to a forward dump position. In the upright position, the spring end is seated into a radially recessed detent portion in the plate member to hold the seat back in its upright position. The leaf spring prevents a slight forward rotation of the seat back when the seat back is unoccupied during normal vehicle operation.
