Abstract

Abstract A car interior finish member where a body portion and a cover portion are integrally molded in a shape retaining thermoplastic resin. The cover portion has a hinge portion and a breakable seam which form an air bag developing port when an air bag is operated. A design sheet is molded integrally with the cover portion and has at least an outer skin layer and a barrier layer. The barrier layer is formed of a material thermally fusible with the thermoplastic resin of the body and cover portions. The hinge portion and breakable seam are formed variously by molding of the cover portion and by appropriate notching up to and through the barrier layer of the design sheet.
