Abstract
An arrangement and closure are disclosed for an air bag deployment opening to be formed in the interior trim structure of an automotive vehicle, the closure including a substrate section weakened in a pattern to form contiguous doors or subsections which split apart along an invisible seam or seams when an air bag is inflated to exert pressure on the inside, and hinge away from the adjacent trim structure to form the opening. A continuous foam plastic layer covers the seam or seams. A skin overlies the foam plastic layer, the skin preweakened in a matching pattern above the seam or seams by being partially cut along the inside surface to a controlled depth.
