Method of manufacturing an automotive airbag enclosure with an embedded heating element |
摘要 |
An automotive instrument panel (IP) has a thermostatically controlled electric heating element for maintaining the plastic material of the IP at a temperature warm enough to inhibit brittle fracture during deployment of an airbag mounted within the IP. The heating element is formed by depositing a layer of electrically conductive material on an inner surface of the outermost layer of the IP along the perimeter of an airbag deployment path, bonding the outermost layer to a substrate, and using a laser to simultaneously score the IP around the deployment path and cut the conductive layer so that it forms a circuit through which electric current may be passed for resistance heating.
