US Patent 7686397 Easy entry seat track release mechanism

A seat assembly for an automotive includes a seat cushion and a seat back pivotally coupled to the seat cushion. A riser mechanism extends between the seat cushion and a vehicle floor. The riser mechanism includes spaced apart front, center, and rear legs each pivotally movable at opposing upper and lower ends. A latch mechanism is operably coupled to each of the center legs for movement between a latched position preventing movement of the front, center, and rear legs relative to the floor and an unlatch position allowing pivotal movement of each of the front, center, and rear legs relative to the floor for moving the seat assembly between a seating position and at least one of an easy entry and forwardly dumped positions.
