ABSTRACT:
A wheelchair fitting apparatus has a laterally adjustable back section, a vertically adjustable footrest and a pair of armrests which are adjustable both vertically and laterally. A back section extender allows vertical adjusting of the back section in relation to the seat section. Suitable indicia, for example a numbered grid on the seat section, the back section and the foot rest, as well as numbered intervals on the front legs of the chair, are provided to facilitate taking of measurements of an individual. The adjustable chair is preferably made of a transparent material to allow pressure and shear, among other things, to be readily observed through the chair. The chair may be adjusted to conform to the basic dimensions of a custom wheelchair for an individual, and measurements may be easily read off of the numbered grid and the numbered intervals on the front legs. Additionally, special cushions and restraint devices may be tested with an individual sitting in the adjustable fitting chair once it has been adjusted to conform to the dimensions of a custom wheelchair for the individual.
