    摘要: 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 differing 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.

    摘要: An airbag apparatus utilizes an interior panel of a vehicle. The interior panel has a rectangular fracture-opening section defined by at least one hinge groove and one fracture groove formed on an inside surface of the interior panel through irradiation with laser pulses. The fracture groove includes bridge portions and continuous hole portions provided alternately. Each of the bridge portions includes no laser-formed hole and has a thickness equal to the interior panel. Each of the continuous hole portions is composed of first holes for fracture which have a first depth and are successively formed between adjacent bridge portions through irradiation with laser pulses, and second holes which have a second depth smaller than the first depth and are each formed between adjacent first holes, through irradiation with laser pulses, so as to remove an original-thickness portion between the adjacent first holes.

    摘要: An airbag apparatus uses an interior panel of an automobile. The interior panel is formed of a multi-layer sheet including a surface layer, an intermediate foam layer, and a base layer. The interior panel has front and rear hinge grooves and left and right fracture grooves for defining a fracture-opening section, and a center fracture groove for dividing the fracture-opening section into front and rear fracture-opening subsections to be split apart from each other in a casement condition. The hinge grooves, the center fracture groove, and the left and right fracture grooves are formed of laser-machined holes which have different depths and do not pass through the surface layer of the interior panel.
