A wheelchair (10) has a chassis (11) with rear wheels (40) and front wheels (18) mounted thereto. A support (29) is pivotally coupled by pivot axis (31) to the chassis (11). A seat mount (19) is pivotally coupled to the support (29). An electric actuator (32) can move the support means to cause the seat mount to be moved between raised and lowered position. A clearance (14) is provided between one or more power supply units (13) and suspension mounts (15) to enable the support (29) to move therein during movement of the seat mount to and from the lowered position. The support (29) and actuator (32) are mounted by a mounting assembly (1la/34) which is mounted by guides (35) so that the mounting assembly can be raised by actuator (33) to further elevate the seat mount (19).

L'invention concerne une chaise roulante (10) qui comprend un châssis (11) sur lequel sont montées des roues arrière (40) et des roues avant (18). Un support (29) est couplé pivotant au châssis (11) à l'aide d'un axe de pivot (31). Un support d'assise (19) est couplé pivotant au support (29). Un actionneur électrique (32) peut déplacer le moyen de support pour faire basculer le support d'assise entre une position relevée et une position abaissée. Un jeu (14) est maintenu entre au moins une unité d'alimentation (13) et des cadres de suspension (15) pour permettre le déplacement du support (29) lors du mouvement du support d'assise vers et depuis la position abaissée. Le support (29) et l'actionneur (32) sont montés à l'aide d'un ensemble de montage (11a/34) fixé au moyen de guides (35), de sorte que l'actionneur (33) puisse élever l'ensemble de montage, et par conséquent, le support d'assise (19).
