Abstract

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.
