Patent ID: 10717397

Abstract:
An interior part having high mechanical strength while having a stitch pattern penetrating a base-material layer is provided. Furthermore, a method for manufacturing an interior part that improves strength of the base-material layer and enhances sewing compatibility is provided.The interior part includes a skin layer joined to one surface of a base-material layer. The base-material layer contains reinforcing fibers and a thermoplastic resin binding the reinforcing fibers. A thread sewn between an opposite surface of the base-material layer with respect to the one surface and a design surface of the skin layer forms a stitch pattern provided on the design surface. A sewn area of the base-material layer is thicker than the periphery. The method includes a shaping step of shaping a fiber-reinforced board in which the thermoplastic resin is softened and forming an area to be sewn thicker than the periphery by releasing compression.
