Abstract
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.

Claim 1
Independent Claim
99 words
An adjustable chair for fitting a wheelchair to an individual, said adjustable chair comprising: a seat section having an upper surface and a front edge; a back section having a front surface which is disposed substantially perpendicularly to the upper surface of the seat section, wherein said seat section and said back section are transparent; and means for laterally adjusting distance from the front surface of the back section to the front edge of the seat section while retaining the substantially perpendicular relationship between the front surface and the back section and the upper surface of the seat section.
Claim 2
Dependent Claim
99 words
An adjustable chair for fitting a wheelchair to an individual, said adjustable chair comprising: a seat section having an upper surface and a front edge; a back section having a front surface which is disposed substantially perpendicularly to the upper surface of the seat section, wherein said seat section and said back section are transparent; and means for laterally adjusting distance from the front surface of the back section to the front edge of the seat section while retaining the substantially perpendicular relationship between the front surface and the back section and the upper surface of the seat section.
Claim 3
Dependent Claim
125 words
An adjustable chair for fitting a wheelchair to an individual, said adjustable chair comprising: a seat section having an upper surface and a front edge; a back section having a front surface which is disposed substantially perpendicularly to the upper surface of the seat section; an adjustable extender, having a top edge, adapted for attachment to said back section, and means for vertically adjusting distance from the top edge of the adjustable extender to the upper surface of said seat section; and means for laterally adjusting distance from the front surface of the back section to the front edge of the seat section while retaining the substantially perpendicular relationship between the front surface of the back section and the upper surface of the seat section.
Claim 4
Dependent Claim
