Abstract
Abstract A supplementary seat-back for vehicles comprising two rigid jointed plates, one functioning as the seat body and the other as the back body. The plates serve as supports for cushions which form the exterior surface of the seat and back bodies. The plates are joined by side hinges and thus are foldable. The cushioning has slits or openings which can be adapted for the user's buttocks and scrotum and the cushion attached to the back plate has a central vertical slit for adapting to the spinal column.
