Abstract
A light weight foldable and customizable wheelchair (4) is described. It is comprised of a tubular frame (9) formed at least in part of molded polymer matrix composite material tubes and connectors. The wheelchair has two side frame tubular assemblies (9, 9′) interconnected in side-by-side relationship by a pair of cross-brace (8, 8′) members. The side frame tubular assemblies define a seating section (6) therebetween. A rear wheel mounting post (80) is secured to each of the side frame assemblies adjacent a rear end section thereof for securing a rear wheel (86) to each of the side frame tubular assemblies (9, 9′) at a desired selected position. A front wheel assembly (7, 7′) is secured to a lowermost front end of each of the side frame tubular assemblies. The seating section (6) is configurable along three axes. Each of the side frame tubular assemblies (9, 9′) is adjustable in depth and in height, constituting a first and second of the three axes, by cutting tubes (70′, 70″, 71, 72) of the side frame tubular assemblies to a desired length and gluing them to associated ones of the connectors (71′, 71″, 72′, 73).
