Abstract
An air support system suitable as a hospital bed comprises a plurality of contiguous, inflatable cells 2. A blower 25 supplies inflation air to the cells. The blower 25 is driven by an electric motor 26 and solenoid valves 29, 50 operate automatically, in the event of electrical power failure, to seal-off inflation air present in the cells. Three-position spool valves 72-74 each operate to direct the flow of cell inflation air through a selected one of three alternative paths.
