Abstract
A cover panel for the air bag in an automotive vehicle with an invisible deployment door section defined by pre-weakened hinge and tear seam formed on the underside of the instrument panel base substrate during the base substrate molding process. The hinge and tear seams are formed into the underside of the base substrate by projections extending from a lower surface mold preform and are differently proportioned in size to provide sequentially operating functions during air bag deployment. Flowing the liquid substrate material into opposing sides of the mold allow for more even cooling and smooth upper surface over the reduced thicknesses of the invisible door hinge and seams.
