Une suspension réglable du fauteuil roulant se présente sous la forme d'un cadre (1), sur le raccord rotatif (2) duquel, situé dans sa partie centrale, est fixé, à l'aide d'une première extrémité, un bras d'inclinaison rotatif (3), alors que sur l'extrémité opposée sont fixés un siège (4) et un dossier mobile (5). Le bras (3) est supporté sur un servomoteur (8). Le servomoteur (8) est fixé à l'aide de raccords d'extrémité rotatifs (9). Le fauteuil roulant comporte une paire de repose-pieds (12), situés sur ses côtés et suspendus de manière inclinée au bras (3). Les repose-pieds (12) sont suspendus à l'aide de tiges (10), qui sont reliées de manière inclinée au bras (3) et au cadre (1) et entre elles à l'aide de raccords centraux rotatifs (11). Le dossier (5) du fauteuil roulant est fixé de façon rotative sur une charnière de verrouillage (6), sur laquelle il est bloqué dans la position de travail, tandis que, lors de la montée ou de la sortie, est supporté sur un meuble (18), formant une plate-forme entre lui et le fauteuil roulant.De plus, le dossier (5) est équipé de deux accoudoirs mobiles (7), situés sur ses côtés. Sur le cadre (1) se trouvent des leviers de basculement réglables (14), à l'extrémité desquels se trouvent des moyeux (15) rotatifs de roues (16) et dans les moyeux (15) se trouvent des moteurs d'entraînement dotés de mécanismes pour faire tourner. Le fauteuil roulant possède un entraînement électrique et boîtier avec carénages. Le support du corps d'un utilisateur (13) pendant l'entraînement forme conjointement au moins le siège (4), les repose-pieds (12) et/ou le soutien de poitrine (17).
