Verfahren zum Herstellen eines Kraftfahrzeugverkleidungsteils mit Schwächungslinien für eine Airbag-Entfaltungsöffnung

摘要

A process for manufacturing a trim piece (10) to provide a concealed deployment door and opening for an air bag in which a substrate panel (12) is formed with one or more integral door panels (14) having an interposed gap (18) preformed between one or more door panels (14) and the substrate panel (12), and one side of each door panel (14) is integral with the substrate panel (12) structure to form a hinge. The substrate panel (12) is overlain with one or more covering layers (20) extending over the door panel or panels and opening. The covering layers (20) can be preweakened along the gap (18) in a correlated pattern, as by laser scoring (26).
