ABSTRACT:
A cushion element for use in the wheelchair. The cushion element includes a generally rectangular body in plane having a front edge, a pair of opposed side edges and a rear edge. The cushion element is sized and shaped to be placed on a seat support of a wheelchair. The cushion element includes at least one collapsible support located toward the front edge of the element. The collapsible support is characterized by being more easily compressed towards the front edge and less easily compressed towards the rear edge. Thereby, under compression, the collapsible support forms a wedge shaped section in cross-section beneath a wheelchair occupant's legs. In this manner, the person is permitted to reach their foot down to the ground without the formation of a pressure point at the front edge of the seat cushion.
