A modular backrest system (30) for a wheelchair (10) is removably attached to backrest posts (26) of the wheelchair. The backrest system includes a back support (34) that provides a surface against which the back of a wheelchair user rests, and a support chassis (32) 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 attachement assembly (42) 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. 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 (182). Another embodiment of the back support includes a pluraltiy of pads (300) adjustably attached to support tubes extending upwardly from the support chassis. Each pad is attached to a support tube by an elbow joint (338). Each pad is attached to the elbow joint by a ball and socket joint (342).
Ce système de dossier modulaire (30) pour fauteuil roulant (10) est rattaché, mais non à demeure, aux montants de dossier (26) du fauteuil roulant. Ce système comporte un dossier (34) offrant un soutien au dos de l'utilisateur du fauteuil roulant et un châssis de support (32) monté sur le dossier afin de le maintenir à l'inclinaison souhaitée par rapport aux montants ainsi qu'à la profondeur de siège souhaitée par rapport au siège. Ce système comporte également un ensemble de connexion (42) connecté opérationnellement au châssis de support en deux points sur les montants afin de faciliter le retrait du châssis de support et du dossier du fauteuil ou leur mise en place sur celui-ci. L'une des réalisations de ce dossier fait intervenir une plaque d'appui et un coussin, ou une pièce rapportée, rattaché à la face de cette plaque d'appui (182). Dans une variante, le dossier comporte plusieurs coussins (300) montés, de manière à être adaptables, sur des tubes de support partant à la verticale du châssis de support. Chaque cousin, qui est assujetti au tube de support par un joint du type joint du coude (338) est rattaché à ce joint par un joint à boulet (342).
