Abstract: A wheelchair construction particularly adaptable for collapsible wheelchairs and which may be formed of all nonmagnetic material, wherein the major components are skinned polymeric foam wheels and panels. The seat and back panels are hingedly supported on side panels, wherein the back panels include a downwardly opening V-shaped channel adjacent the center hinge which receives the upwardly foldable seat panels as the wheelchair is collapsed and the seat panels are supported in an overcenter hinge position on transverse foldable panels. The side panels include openings at their upper rearward corners forming integral C-shaped handles and the footrests are supported in a horizontal use or angled non-use position in configured slots formed in a support block.
