An adjustable back system for releasable attachment to spaced-apart substantially vertical wheelchair frame posts (52). The back system includes a relatively rigid shell back (36) formed to extend transversely between the posts (52) for support of a user's back, a plurality of post-engaging assemblies (50) coupled to shell back (36) by a plurality of independently adjustable coupling assemblies. The post-engaging assemblies (50) including an upper pair of post-engaging assemblies extending transversely from opposite sides of shell back (36) and a lower pair post-engaging assemblies extending transversely from opposite sides of shell back (36) below upper post-engaging assemblies. The post-engaging assemblies (50) each are formed to releasably secure shell back (36) to the posts (52), and the adjustable coupling assemblies are formed for independent fore and aft adjustment of the position of coupling of post-engaging assemblies (50) for adjustment of the angle and depth at which shell back (36) is mounted to posts (52). The adjustable coupling assemblies further including connecting members (79) extending between upper post-engaging assembly and lower post-engaging assembly on each side of shell back (36), the connecting members (79) being formed to rigidly interconnect the coupling assemblies to enable fore and aft adjustment of the depth of shell back (36) relative to posts (52) while maintaining substantially the same angle of shell back (36) relative to posts (52).

Deformity back system

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.

A lightweight contoured base for a seat cushion is produced by first forming a shaped lightweight foam core with a void corresponding to the ischial tuberosities of a user and then forming a sandwich assembly by placing a layer of foam or foamable material against both upper and lower surfaces of the shaped lightweight foam core to form a sandwich assembly. The sandwich assembly is then molded to produce the finished contoured base for a seat cushion.

Method of making a seat cushion base

A coupling assembly for connecting adjacent ends of conduits, primarily used for aircraft fuel lines having redundant locking features is provided. This coupling can be manipulated with one hand and includes laterally spaced locking tines which engage raised elements for locking the coupling in secured relationship. The coupling assembly can be manipulated with one hand and has viewing ports to be sure that all parts are in place. Also, the tines and guide members are configured to create a force between the two with a longitudinal component tending to open the assembly.

Conduit coupling device with redundancy features

A coupling assembly for connecting adjacent ends of conduits, primarily used for aircraft fuel lines having redundant locking features is provided. This coupling can be manipulated with one hand and includes a central tine and laterally spaced locking tines which engage a mating channel for locking the coupling in secured relationship. Indicia is provided across the locking tines which is not visible when the coupling assembly is completely and securely closed. The coupling assembly can be manipulated with one hand and has viewing ports to be sure that all parts are in place. Also, the tines and guide members are configured to create a force between the two with a longitudinal component tending to open the assembly.
