A modular backrest system for a wheelchair is removably attached to backrest posts of the wheelchair. The backrest system includes a back support that provides a surface against which the back of a wheelchair user rests, and a support chassis mounted to the back support for supporting the back support at a desired incline with respect to the posts, and at a desired seat depth with respect to the seat. An attachment assembly is further included that is operably connected to the support chassis at two locations and to the posts to allow the support chassis and back support to be readily removed from or attached to the chair. The particular back support employed in conjunction with the support chassis is based upon the support needs of the wheelchair user. One embodiment of the back support includes a backing plate, and a cushion or insert attached to a forwardly presented face of the backing plate against which the back of the individual rests when sitting on the seat. Another embodiment of the back support includes a plurality of pads adjustably attached to support tubes extending upwardly from the support chassis. Each pad is attached to at least one of the support tubes at a desired location by an elbow joint that permits forward and rearward movement and side-to-side movement of the pad. Each pad is attached to the elbow joint by a ball and socket joint that permits rotational movement of the pad with respect to the second member.

[ What is claimed is:] [26.] A backrest system for a chair for seating an individual, said chair having a seat and upright posts extending upwardly from the rear of the seat in a spaced apart, substantially parallel manner, said backrest system comprising:a back support adapted to be removably positioned between said posts to support a back of an individual sitting on the chair seat;a support chassis adapted to be disposed between said posts and mounted to said back support for supporting said back support at a desired incline with respect to said posts;a pair of support tubes attached to said support chassis and extending vertically therefrom in a substantially parallel, spaced apart manner; andan attachment assembly connectable to each of said posts for releasably securing said support chassis to said posts;said back support including a plurality of pads mounted to said support tubes at desired locations based upon support needs and proportions of the individual; each of said pads being movable inwardly, outwardly and laterally with respect to said support tubes and at forward and rearward inclines with respect to said support tubes to provide a support surface for the individual sitting on the seat based upon that individual's dimensions and support needs, each pad being attached to at least one of said support tubes by an elbow joint that permits inward, outward and lateral movement of said pad.
