CA 2708528

The invention provides a variety of devices for supporting at least a portion of a user's body. In some embodiments, the invention provides a support device which includes a bladder capable of containing a fluid and a post adjacent the bladder. The bladder may form a rolling diaphragm portion with the post such that when a force is applied to the bladder, the rolling diaphragm portion of the bladder rolls along the post decreasing the volume of the bladder. In some embodiments, the invention provides a post which includes a reduced cross-sectional area in comparison to an adjacent region of the post such that the resistance of the rolling diaphragm portion of the bladder to rolling movement along the post due to the applies force decreases as the bladder rolls along the reduced cross-sectional area region. In some embodiments, the support device includes a plurality of bladders and/or a plurality of posts.

L'invention concerne divers dispositifs destinés à soutenir au moins une partie du corps d'un utilisateur. Dans certains modes de réalisation, l'invention concerne un dispositif de support comprenant une vessie destinée à contenir un fluide et une tige adjacente à la vessie. La vessie peut former une partie diaphragme roulant avec la tige de sorte que, lorsqu'une force est appliquée sur la vessie, la partie diaphragme roulant de la vessie roule le long de la tige, réduisant ainsi le volume de la vessie. Dans certains modes de réalisation, l'invention concerne une tige présentant une coupe transversale réduite par rapport à une zone adjacente de la tige, de sorte que la résistance de la partie diaphragme roulant de la vessie au mouvement de roulement le long de la tige du fait de la force appliquée réduit à mesure que la vessie roule le long de la zone à coupe transversale réduite. Dans certains modes de réalisation, le dispositif de support selon l'invention comprend une pluralité de vessies et/ou une pluralité de tiges.
