Abstract
A supplemental gas assembly ( ) such as used for aircraft crews is provided which includes a mask ( ) adapted to fit over at least the nose and mouth of a wearer, together with a flexible, self-elongating hose assembly ( ) and a stowage box ( ) for receiving the mask ( ) and hose assembly ( ); the assembly ( ) is designed so that when the mask ( ) is pulled from the box ( ), pressurized gas passing through the hose assembly ( ) serves to inflate and axially expand the assembly ( ) to a deployed length greater than the relaxed length thereof. The assembly ( ) preferably includes an inflatable elastomeric inner tube ( ) together with an exterior sheath ( ) of woven or braided material which restricts radial expansion of the tube ( ) while permitting axial expansion thereof. In preferred forms, the deployed length of the assembly ( ) is up to three times greater than the relaxed length thereof.
