ABSTRACT:
An inflatable head harness for quickly orienting and securing a device, such as a respiratory mask, in position on the head of a user. The harness comprises a loop to fit around the head, the loop having a longitudinally elastically extensible outer tube and a folded, inflatable, substantially inelastic inner tube positioned within the outer. The inner tube has a greater length than the outer tube and is positioned therein in folded or pleated form. The inner tube is enlarged by means of pressurized fluid, causing the outer tube to extend longitudinally to thereby increase the diameter of the loop and enable it to be slipped over the head. When the pressure is released, the elasticity of the outer tube causes it to contract longitudinally so that the loop is in gripping engagement with the head of the user.
