Abstract: There is described a wheelchair frame including first and second side frame members each having a first, rearward section designed to be coupled to a seat portion of a wheelchair and a second, forward section designed to be coupled to a foot portion of the wheelchair wherein the rearward and forward sections are connected to one another to form a substantially L-shaped profile. Each of the first and second side frame members exhibits, at least in part, a varying cross-section and further has an intermediate section shaped to act as a hand grip, which intermediate section is interposed between the rearward and forward sections and exhibits a cross-section that differs from a cross-section of the rearward section and/or forward section. The rearward section, the intermediate section and the forward section are successive sections of a same integral piece that is shaped to exhibit the varying cross-section.

Abstract: The caster wheel support assembly has a first section securable to a frame member of a wheelchair and a second section holding a swivel member coupled to a caster wheel. The caster wheel support assembly has a holding member designed as a collet configured to hold a first portion of the swivel member which extends along a first axis. A second portion of the swivel member, which is coupled to the caster wheel, extends away from the first portion along a second axis which forms an angle relative to the first axis. The first portion of the swivel member is supported by the holding member to selectively allow rotation thereof relative to the holding member about the first axis, causing adjustment of a camber of the caster wheel. The collet is configured to selectively prevent or permit rotation of the swivel member relative to the holding member.
