Abstract

La présente invention concerne un fauteuil orthopédique doté d'une paire de cadres de soutien et d'au moins une paire de supports. Une extrémité de chacun des deux supports est accouplée à l'un de chacun des deux cadres de soutien, et un cadre de fauteuil est accouplé à l'autre extrémité de chacun des deux supports autour de l'axe de rotation du cadre de fauteuil, ce qui permet à l'angle d'inclinaison du fauteuil d'être manuellement modifié, depuis une première position jusqu'à une seconde position. Dans un mode de réalisation de la présente invention, le fauteuil comprend un dispositif de préhension accouplé à une extrémité de la paire de supports, permettant au cadre de fauteuil d'être basculé autour du cadre de soutien et d'être verrouillé dans une position.
