Inner-decoration component for automobile and method for the production thereof

Abstract

Provided are an installation structure on a light decorated back face, used for simply and cheaply installing other parts to the whole or a part of inner-decoration component for automobile and an installation method. A door decoration upper portion-forepart (a laminating structure) (30) of a door decoration (20) is formed by a light laminating body with a foamex substrate (31) with the conformality and a rigid resin rib (31) which is integrated with the substrate and arranged on the back face, and is taken as a structure for installing a waist ornament (other components) (50) on the back side, a part of waist ornament is fused to be integrated by a hump (34) used for fusion splicing and integrated on the resin rib (32), and the part of the waist ornament, corresponding to the end edge portion of the door decoration upper portion-forepart uses the coiling process by means of the coiling material (35) at the circumference of the foamex substrate, the upper terminal (50a) of the waist ornament is kept by the coiling of the coiling material, thus simplifying the conformality shape of the waist ornament.

Description

technical field [0001] The present invention relates to automotive interior parts such as door decorations, rear trays, floor decorations, rear cargo box decorations, trunk decorations, roof decorations, and rear side decorations, and their manufacturing methods. An automotive interior part in which other parts such as a gasket are simple and inexpensive, and which has a good appearance and is mounted on the rear side of a laminated structure, and a method for manufacturing the same. Background technique [0002] For example, to instantiate a door decoration, based on Figure 21 , Figure 22 The structure of an automotive interior part will be described. The door trim 1 has shape retention and mounting rigidity to the door panel, and is formed integrally by laminating a skin 3 with a good surface appearance on the surface of a resin core 2 covering substantially the entire surface of the product. As the above-mentioned resin core material 2, a polypropylene-based resin mix...

AI Technical Summary

Problems solved by technology

However, in order to attach and fix other parts 14 such as decorations, brackets, and gaskets to the back side of the door trim 10, for example, a welding and fixing structure by welding protrusions 15 or a hot-melt adhesive layer 16 may be considered. However, in the method of using the welding protrusion 15, since the setting position of the welding protrusion 15 is restricted in terms of mold processing to the forming metal mold, the setting position of the other parts 14 is restricted. There is a disadvantage that the degree of freedom of design is restricted, and since the welding protrusions 15 are set at multiple locations, and each welding protrusion 15 is caulked, the processing is complicated and takes a lot of work time, etc. There is a problem in workability

[0009] Additionally, when using Figure 27 In the method of the hot-melt adhesive layer 16 shown, the application process of the hot-melt adhesive layer 16 is also required, and there is a problem that the number of man-hours increases, which leads to an increase in cost, and is not preferable in terms of the working environment.
