Abstract

A vehicle seat for a vehicle. The seat moveable into a stadium position in which a seat cushion assembly and a seat back assembly are substantially upright. The seat can also include incline and recline features which allow the seat back to fold forward to kneel on the seat cushion and to recline backward to a flat position. The stadium positioning provides, amongst other benefits, easier access to an area behind the seat.
