Patent

CA 2496875

An automatically engageable and releasable brake apparatus adaptable to be attached to a wheelchair is provided, including a connection mechanism adapted to be positioned on a rear frame portion of the wheelchair frame, a seat actuation member adapted to be positioned on the wheelchair seat, a brake actuating member coupled to the connection mechanism and in fluid communication with the seat actuation member defining a closed fluid system therewith, and a brake member coupled to the brake actuating member and adapted to contact a ground surface on which the wheelchair is located. Occupational ingress into the wheelchair causes fluid to flow from the seat actuation member to the brake actuating member, which causes the brake member to move from a first position in substantial contact with the ground surface on which the wheelchair is located to a second position spaced a distance above the ground surface.

L'invention concerne un appareil de freinage automatiquement activé et désactivé, et adapté pour être fixé à un fauteuil roulant, comprenant un mécanisme de connexion adapté pour être positionné sur une partie arrière de la structure du fauteuil roulant, un élément de commande du siège adapté pour être positionné sur le siège du fauteuil roulant, un élément de commande du frein couplé au mécanisme de connexion et en communication fluidique avec l'élément de commande du siège, définissant un système fluidique fermé, et un élément de freinage couplé à l'élément de commande du frein et adapté pour venir en contact avec une surface du sol sur laquelle est situé le fauteuil. L'occupation du fauteuil permet au fluide de s'écouler de l'élément de commande du siège vers l'élément de commande du frein, l'élément de freinage se déplaçant ainsi d'une première position sensiblement en contact avec la surface du sol sur laquelle se situe le fauteuil roulant sur une seconde position espacée d'une certaine distance au-dessus de la surface du sol.
