Abstract: An automotive vehicle seat which is convertible to a folded cargo configuration includes a seatback pivotable about its lower edge to lie flat and form a cargo floor extension over the area occupied by the seat bottom. The seat bottom includes separate main pelvic support and high bolster portions on the vehicle floorpan and the high bolster portion is swingable from its normal position adjacent the main portion to a stowed position permitting the seatback to be foldable into the seat bottom space. Latch means between the seatback and bolster portion hold the same in their cargo position and the bolster portion is spring-urged to normal position.
