Wheelchair seating cushion having adjustable top contour shape

Abstract

Seating cushion assembly (10) for use with a wheelchair having a seat base (20). A flexible foam cushion (30) is mounted on base (20) with at least one insert member (40) removably positioned at a support location (33) between the foam cushion (30) and the base (20) to upwardly or outwardly raise a top surface (5) of the foam cushion (30) at the support location (33). The resulting lateral support contour (35) in the top surface (5) of the cushion assembly provides user stability and pressure distribution while seated on the seating assembly (10) and yet the user can selectively eliminate or remove the contours (35) by removing the contour-forming inserts (40). The foam cushion (30) further has sufficient thickness and resiliency to permit the user to temporarily sit directly over the contour-forming insert member (40) during use of the cushion assembly (10), which enables safe use of the entire area of the wheelchair cushion assembly (10).
