Abstract
A fully portable pillow-like device is provided, shaped for comfortable restrain of head movement, and including a sectioned inflatable bladder for shaping the support to conform to any particular user's requirements. The bladder is constructed in 3 independent zones, each separately inflatable to differing degrees of internal pressure and firmness. Inflation means is provided for each of the inflatable bladder zones, and in the preferred embodiment, the inflation means consists of independent pumps, one for each zone, which are fully contained within the perimeter of the bladder form. The pump means consists of a chamber enclosing a resilient volume of open cell foam rubber or other sponge-like material, which when pressed will draw air from an inlet valve and expel it via an outlet check valve into a connected inflatable chamber. A relief valve is also provided at each pump in order that the gas pressure in the inflatable chamber may be adjusted to the user's preference.
