Abstract
Method and apparatus for reversing and flattening a driver's restraint cushion composed of a pair of overlapping sheets. The apparatus includes a loading platform having an aperture therein of a size generally corresponding to the size of a circular opening centrally formed in one of the sheets of the restraint cushion. A retainer ring surrounds the aperture and extends into the circular opening of the restraint cushion when the latter is positioned on the loading platform. Subsequently, a vertically movable ram engages and forces the other of the sheets of the restraint cushion through the aperture so as to cause the inside and outside surfaces of the two sheets to reverse after which pressurized air flows through the ram to inflate the cushion and a flat plate presses the inflated cushion into a pancake form.
