Abstract
A seat cushion for use in a wheelchair comprises a shaped tray and a filled envelope. The envelope is filled with a fluid like material which is flowably displaceable under the weight of a user. The shaped tray comprises a recess for receiving the buttocks region of the user as well as a front edge over which the legs of the user extend. A back wedge is mounted along a back edge of the tray and keeps the filled envelope from sliding over the back edge of the tray. Further, side wings located at the sides of the shaped tray near its front edge help constrain the legs of the wheelchair user in a generally forward direction within the width of the wheelchair seat. Side wedges mounted on the underside of the seat are selectively removable to accommodate the presence of a cross brace mechanism, as is commonly used in drop seat wheelchairs.
