Abstract
A wheelchair back system adapted to provide a customized fit to the user. The system includes a rigid back shell removably affixed to the wheelchair, a plurality of foam blocks, and a pad member containing flowable fluid material. The back shell has a forward facing, front surface and the foam blocks are removably positionable forward of the back shell to form a substantially continuous layer of foam of substantially uniform depth forward of the back shell. Each foam block is individually and separately removable to provide a recessed area in the otherwise continuous layer of foam to provide a customized fit to the user. The pad member overlies the front surface of the foam blocks and is received in any recessed area formed by the removal of a foam block. In this manner, the system can be customized to the deformities or other abnormalities of each individual user.
