Abstract

L'invention concerne un accessoire pour repose-pieds de chaises roulantes qui, formé à partir d'un élément pliable, accouplable à la structure d'une chaise (2) roulante de manière fixe ou de manière démontable, comprend essentiellement : une plateforme (3) d'appui, qui peut être pliée d'une position horizontale d'utilisation à une position verticale de non utilisation et vice versa ; et une armature (4) de support à l'extrémité inférieure de laquelle est accouplée, au moyen de la liaison articulée (5), la plateforme (3) d'appui et présentant, à l'extrémité supérieure, des moyens d'ancrage (6) au tube avant de la structure de la chaise (2). Ledit accessoire comprend un mécanisme de pliage (7), manuel ou automatique, de la plateforme (3) d'appui relié à un actionneur (8) qui est situé en un point facile d'accès pour l'utilisateur de la chaise lorsqu'il est assis sur celle-ci, pour déplacer ladite plateforme (3) d'une position à une autre sans avoir à se pencher ou à se lever. Préférablement, l'accessoire pour repose-pieds de chaises roulantes comprend un moyen d'avertissement (9) qui indique à l'utilisateur la position dans laquelle est la plateforme (3) d'appui sans avoir à voir physiquement la position dans laquelle elle se trouve.
