Abstract
Abstract A protective pillow assembly incorporates an air-impervious transparent plastic hood. In case of fire, the hood is placed over the user's head, the assembly being so arranged that the user breathes through the pillow, or pillow batting, which acts as a smoke filter. In one embodiment, a special pillow instruction is used. An outer air-pervious sleeve cooperates with an inner sleeve, which has an air-pervious portion and an air-impervious portion, to support pillow batting. The transparent sleeve is sealed to the air-impervious portion. In a second embodiment, a conventional pillow is inserted into an air-pervious sleeve, which is connected in overlapping relationship to the transparent hood. In both embodiments, the hood is folded and stored within the assembly. The hood may be formed of a polished polypropylene film or a lamination of Mylar film and a noise-deadening film, such as polypropylene or polyvinyl chloride. A heat-reflective thin metallic coating is incorporated in the lamination. The pillow batting may be treated with a carbon monoxide neutralizing substance.
