ストが嵩むものとなっている。[0003] The instrument panel as a vehicle interior member includes an outer surface portion of a panel base material formed into a required shape.
An instrument panel in which a urethane foam having elasticity is interposed between the panel base material and the skin material, as a skin material is attached to the (outer surface portion facing the passenger compartment side),
There is an instrument panel or the like in which a single-layer or multiple-layer skin material is directly adhered to the outer surface of a panel base material. Among these, the instrument panel is formed using a foaming mold, and a skin material and a panel base formed in a required shape in a previous step are set in a foaming mold, and are defined therebetween. It is manufactured by foaming and solidifying a urethane stock solution in a space. Therefore, at the time of forming each of the skin material and the panel base material, a thin breakable portion extending along the contour of the airbag door can be formed in advance at a portion where the airbag door is to be formed. Therefore, it is possible to form the airbag door integrally with the panel base (skin material). That is, when the passenger airbag device is activated and the airbag is inflated, the airbag door is opened as the airbag door to the occupant compartment side by bending the portion to be broken by the pressing force from the inside. Displaced), whereby the airbag is deployed from the opening thus defined. Such an instrument panel has an advantage that the airbag door constitutes a part of the panel base material before the operation of the passenger seat airbag device, so that the texture of the entire panel can be improved. Due to the large number, the production cost is increased.
