Abstract
The present Invention provides for an automobile-use interior cover for accommodating an airbag apparatus, the said cover 11 being processed to have an airbag expansion and release-use fracture-opening weakened line section. The automobile-use interior cover 11 consists of a single laminated layer by laminating in such a manner of welding a hard polypropylene resin base plate layer 111 of desired thickness, a middle layer of foamed polypropylene resin 112 of desired thickness that is attached to the upper surface of the hard polypropylene base plate 11, and an outer upper layer 113 covering and attached to this foamed polypropylene resin middle layer 112. The outer upper layer 113 itself consists of two component layers 113A and 113B, both composed of thermo-plastic polyolefin (TPO) , each of which is made of material differring from each other in the degree of their physical ability to absorb infrared radiation. The lower cover layer component 113B having a high rate of absorption of infrared radiation is positioned facing to the surface of the foamed polypropylene resin middle layer 112.
