Abstract
A safety cushion apparatus having a very short reaction time is attachable to automotive vehicle belt-type restraints for softening the shock of sudden constraint against the user's body and to maintain the belt restraints with an appropriate degree of tautness. The apparatus includes an inflatable cushion that is longitudinally folded to a compact, strap-like configuration conforming to the shape of the belt restraint, a flat, slim inflator being enclosed within and surrounded by the folded cushion. The folded cushion is releasably enclosed within an outer cover to which it is attached, the outer cover being attached to the underside of the belt restraint and fastened over the folded cushion by a long zipper. Velcro hook and hoop fastening material is utilized for attaching the cover to the belt restraint and the zipper. The inflator is actuatable by a crash impact sensor mounted on the vehicle and is operable to generate an innocuous gas for inflating the cushion, the cover being automatically opened upon such inflation of the cushion.
