Deformity back system

A wheelchair back system adapted to support the back of a human, said system being adapted to provide customized fit to a wheelchair user, said system comprising:

• a rigid back shell;
• mounting means to removably affix said rigid back shell to a wheelchair;
• a plurality of foam blocks and a thin shim interposed between said rigid shell and said foam blocks, said thin shim having a front surface and said system further including means for removably attaching said foam blocks to the front surface of said thin shim, said foam blocks providing a substantially continuous layer of foam of substantially uniform depth over the front surface of said thin shim, said foam blocks being individually and separately removable from said thin shim to provide a recessed area in said substantially continuous layer of foam to provide customized fit to wheelchair users;
• and
• a pad member being sized to overlie the front surface of said foam blocks, said system further including means for attaching said pad member to the front surface of said foam blocks and to the front surface of said thin shim in any recessed area formed by the removal of a block.

A wheelchair back system adapted to support the back of a human, said system being adapted to provide customized fit to a wheelchair user, said system comprising:

• a rigid back shell having lateral edges and a pair of flanges extending forwardly from the lateral edges;
• mounting means affixed to said flanges to removably affix said rigid back shell to a wheelchair;
• a plurality of foam blocks, said back shell having a front surface and said system further including means for removably attaching said foam blocks to the front surface of said back shell, said foam blocks further having a front surface and providing a substantially continuous layer of foam of substantially uniform depth over the front surface of said rigid back shell, said foam blocks being individually and separately removable from said rigid back shell to provide a recessed area in said substantially continuous layer of foam to provide customized fit to wheelchair users;
• and
• a pad member comprising an envelope containing a flowable fluid being sized to overlie the front surface of said foam blocks, said system further including means for attaching said fluid pad to the front surface of said foam blocks and to said back shell in any recessed area formed by the removal of a block.

• a rigid back shell-having lateral edges and a pair of flanges extending forwardly from the lateral edges;
• mounting means affixed to said flanges to removably affix said rigid back shell to a wheelchair;
• a plurality of foam blocks and a thin shim interposed between said rigid back shell and said foam blocks, said thin shim having a front surface and said system further including means for removably attaching said foam blocks to the front surface of said thin shim, said foam blocks providing a substantially continuous layer of foam of substantially uniform depth over the front surface of said thin shim, said foam blocks being individually and separately removable from said thin shim to provide a recessed area in said substantially continuous layer of foam to provide customized to wheelchair users;
• and
• a pad member comprising an envelope containing a flowable fluid being sized to overlie the front surface of said thin shim, said system further including means for attaching said fluid pad to the front surface of said foam blocks and to said thin shim in any recessed area formed by the removal of a block.

A wheelchair back system adapted to support the back of a human, said system being adapted to provide customized fit to a wheelchair user, said system comprising:

• a rigid back shell;
• means for mounting said rigid back shell to a wheelchair;
• a plurality of foam blocks, said back shell having a front surface facing forward and said system further including means for removably positioning said foam blocks forward of the front surface of said back shell, said foam blocks further having a front surface and providing a substantially continuous layer of foam forward of the front surface of said back shell, said foam blocks being individually and separately removable to provide a recessed area in said substantially continuous layer of foam to provide customized fit to the wheelchair user;
• and
• a pad member sized to overlie the front surface of said foam blocks between the wheelchair user and the foam blocks and forward of the rigid back shell with a portion of the pad member assuming a position extending and received in any recessed area formed by the removal of a block, said system further including means for retaining said portion of said pad member in said position extending and received in said recessed area forward of said rigid back shell and between the wheelchair user and the rigid back shell.
