Title
(EN) PNEUMATIC WHEELCHAIR CUSHION
(FR) COUSSIN PNEUMATIQUE POUR FAUTEUIL ROULANT
Abstract
(EN)
A pneumatic wheelchair cushion system (10) has an air cushion (12) with adjoining separate chambers (18-26) for cushioning a user's coccyx, ischial tuberosities, greater trochanters and thighs. The chambers (18-26) are pneumatically interconnected with each other such that pressure on one or more of the chambers is transmitted to the other chambers and to a control module (16) with a controller for maintaining an inflation pressure in the air cushion (12) within an upper and a lower set point.
(FR)
Un système de coussin pneumatique (10) pour fauteuil roulant comprend un coussin d'air (12) comportant des chambres séparées contiguës (18-26) pour amortir les chocs transmis au coccyx, aux tubérosités ischiatiques, aux grands trochanters et aux cuisses de l'utilisateur. Les chambres (18-26) sont reliées les unes aux autres pneumatiquement de sorte que la pression appliquée sur une ou plusieurs chambres soit transmise aux autres chambres et à un module de commande (16) comprenant un contrôleur servant à maintenir une pression de gonflage dans le coussin d'air (12) entre un point de réglage supérieur et inférieur.
