Abstract

L'invention concerne une chaise pour personnes handicapées comportant un châssis (10), une chaise (13), un dispositif de levage (12) et un mécanisme (29-31) permettant de basculer sélectivement la chaise en avant. La chaise est montée sur le châssis au moyen du dispositif de levage (12), lequel est conçu pour conférer à la chaise (13) un mouvement combiné vers le haut et vers l'avant. Une telle chaise peut servir de fauteuil hygiénique. Elle peut également servir à aider l'utilisateur à passer d'une position assise à une position debout. Lorsqu'une personne, ou un utilisateur, est assis sur la chaise de sorte que ses pieds touchent le sol, il est possible de rehausser la chaise au moyen du dispositif de levage (12) afin d'étendre les jambes de l'utilisateur et, parallèlement, de la basculer vers l'avant grâce au mécanisme de basculement (29-31). Ce mouvement de la chaise, combiné à son mouvement vers l'avant causé par le dispositif de levage, pousse en avant le postérieur de l'utilisateur, ce qui permet à ce dernier de passer d'une position assise à une position debout. Inversement, une personne peut être aidée à passer d'une position debout à une position assise par l'exécution dans l'ordre inverse des opérations décrites ci-dessus.
