Method for producing a laser-scored instrument panel with an airbag opening with an invisible joint

摘要

A process for forming an instrument panel or other motor vehicle interior trim component having a laser scored invisible deployment restraint system opening. Processing of such components having foam material layers often produces compression forces in the foam. Heat ageing of the foam causes the compression set to be relieved, which causes the deployment seam line to become visible. In this invention the part is heated prior to laser scoring to relieve compression forces within the foam layer prior to laser scoring.
