<p>This invention is concerned with flameproofed mattresses, pillows and sleeping bags, pads, cushions for chair or sofas, and so on. The flameproofed materials of the present invention may be formed of (1) a close-woven fabric attached to (2) a thick layer (e.g., 0.1-1 inch) of resilient self-extinguishing polyruethane cushioning foam having (3) a metallized heat-conductive layer, such as of aluminum, which dissipates heat rapidly, thereupon, the metallized foam being secured to (4) filling or padding with (5) a backing fabric secured thereto. The parts are suitably locally secured together by tying means such as stitching, tufting, dielectric welding or the like. The object is to protect the main body of highly combustible filler material in cushions, pillows, mattresses, sofas, upholstered chairs, and the like from fire in case of the dropping of a match, cigarette, or the like on the cover fabric or ticking by someone, such as a careless smoker. Even though the foam is self-extinguishing relative to a lighted cigarette, when not compressed, when it is compressed by tying as by stitching, the heat may be conducted therethrough and ignite the filling or stuffing, if no metal layer is present.</p> |
