A self-inflating support device or cushion (10) consists of an envelope (11) defining a closed space, a compressible material contained within the envelope (11) and valve means (15) adapted to allow air into the envelope (11) so that the compressed material can expand to enlarge the support device (10) and to allow air out of the envelope (11) so that the material may be compressed and the support device (10) reduced in size. The valve means (15) comprises a valve member (21) and a valve seat (22) adapted to form a seal therebetween when the valve (15) is closed, an actuator (20) which whilst actuated separates the valve member (21) and valve seat (22) to permit air flow into and out of the device (10) for adjustment of the volume of air within the device (10) and locking means (26, 47) for maintaining the valve (15) fully open when it is desired to fill or empty the device (10) with air.

La présente invention concerne un dispositif support ou un coussin auto-gonflant (10) constitué d'une enveloppe (11) définissant un volume clos, d'un matériau compressible contenu dans l'enveloppe (11) et d'une valve (15). Cette valve est conçue, d'une part pour admettre l'air dans l'enveloppe (11) de façon que le matériau comprimé puisse s'expanser pour augmenter les dimensions du dispositif support, et d'autre part pour laisser l'air sortir de l'enveloppe (11) de façon à pouvoir comprimer le matériau pour diminuer les dimensions du dispositif support (10). La valve (15) est constituée, d'une part d'un piston (21) et d'un siège de valve (22) conçus pour créer l'étanchéité entre eux lorsque la valve (15) est fermée, d'autre part d'un actionneur (20) qui, lorsqu'il est mis en oeuvre, sépare le piston (21) du siège de valve (22) pour permettre à l'air d'entrer et de sortir du dispositif (10) pour régler le volume d'air à l'intérieur du dispositif (10), et enfin d'un organe de verrouillage (26, 47) permettant de conserver la valve (15) complètement ouverte lorsqu'on souhaite remplir d'air le dispositif (10) ou l'en vider.
