Abstract
Abstract A disposable adjustable headrest which can be used either as a headrest, a pillow or a cushion. According to one aspect of the invention, at least a pair of pillow units are placed in a common pillowcase. The pillow units are preferably elongated, made of resilient material and disposed in the common pillowcase at a manually adjustable distance from each other. When disposed an appropriate distance away from each other in the common pillowcase there is formed a convenient headrest supporting both sides of the back of the head of a person sitting in a chair and having placed the pillowcase against the front of the seat back or, when the pillow units are disposed close to each other in the pillowcase they form a voluminous headrest pillow arrangement for supporting one side of a head or, alternatively, for forming a convenient cushion. Various diverse structures are contemplated for practicing the invention which, in addition to placing separate pillow units in the common pillowcase, include placing each pillow unit in a separate pillowcase and disposing one of the pillowcases within the other, or attached to the other. The adjustable headrest and pillow of the invention is capable of use as such or in combination with a modified conventional disposable head cloth or sheet draped over the seat back of mass transportation vehicles.
