  • Reinforced air bag door cover and method for making same
    Patent number: 5527574
    Abstract: A method is disclosed for forming a reinforced plastic skin for an automobile interior trim structure. The method includes the steps of supplying a plastic material onto a mold surface, heating the plastic material to fuse it into a unitary layer, embedding a reinforcing material into the layer, and cooling the plastic and reinforcing materials. The method can be used to reinforce an air bag door cover by incorporating a tear seam into the plastic layer and embedding the reinforcing material into the layer such that it surrounds the tear seam. The reinforcing material aids in rupturing of the cover along the designated tear seam during deployment of the air bag. Also disclosed is an air bag door cover formed in accordance with the disclosed method.
