Abstract: An adjustment apparatus for a wheelchair back that can be used with various backs, that can be adjusted in a plurality of ways using a single adjustment point, and that can be adjusted without the use of tools. In another aspect, includes a support mechanism for mounting an adjustment apparatus for a wheelchair back that can be engaged using gravity, that provides at least one support point, and that can be utilized without the use of tools. Still another aspect of the wheelchair back assembly includes a mounting clamp that is simple in construction, that provides at least one support point, and that can be easily disassembled and adjusted to accommodate upright frame members of various diameters without the use of a tool.

Abstract: A mounting clamp assembly that provides at least one support point for a wheelchair back mounting assembly, the mounting clamp assembly includes a clamp block and threaded clamp fastener extending through the clamp block and engaging a support by which the mounting clamp can be secured to a wheelchair cane; the mounting clamp assembly can be easily disassembled and adjusted to accommodate upright frame members of various diameters without the use of a tool.

Abstract: A system for attaching a wheelchair back to wheelchair posts comprising a bracket and interchangeable attachment hardware secured to the bracket. In one aspect the bracket can be adjusted vertically relative to the wheelchair back and can be adjusted on a horizontal path. In one aspect, the angular orientation of the attachment hardware can be adjusted to adjust the angular position of the wheelchair back relative to the wheelchair seat and posts. In one aspect the attachment hardware is represented by a hanger assembly. In one aspect the attachment hardware is represented by an expansion plug assembly for insertion into the open tubular end of a wheelchair post.

Abstract: A supportive back rest for attachment to an original equipment back rest of a wheelchair to enhance the supportive characteristics of the wheelchair back rest. The supportive back rest includes a cushion, a suspension element and a cover. The cushion and one side of the suspension element are positioned in the cover. An opposed side of the suspension element is exposed and defines a space between it and the cushion. The suspension element slips over the upper edge of the original equipment back rest of the wheelchair to suspend the supportive back rest in position behind a seated user. The suspension element can be attached to the cover or can be attached to the cushion by molding or through attachment anchors.
