Description

  The present invention relates to an anti-skin peeling prevention structure after attaching a mating member to a skin-attached material in an automobile interior product in which the outer periphery of a base material is covered with a skin.

  For armrests, dashboards, and console box covers that are automobile interiors, a base layer made of a synthetic resin material such as polypropylene resin or ABS resin and a skin layer such as vinyl chloride or synthetic leather using a mold. Many of them use a skin-attached material produced by integrally molding and. The skin layer mainly has functions such as providing a soft tactile sensation to the user and producing a high-class feeling. However, if the epidermis layer end is not properly treated, wrinkles, slack, slippage, or peeling may occur partially or entirely over the epidermis. Various skin peeling prevention structures have been devised in the past for these problems.

  Patent document 1 has shown an example of the terminal process which prevents peeling of the skin joined to the outer periphery of a base material. This peeling prevention structure is formed from a base material to which the skin is bonded, and a thin wall portion which is an edge of the base material and has a reduced thickness. After demolding, the thin-walled portion is partially heated with its outer skin bonded to the surface, folded back to the substrate side that is the back surface, and the opposite substrate surfaces are fused again. . Accordingly, it is possible to perform terminal processing in a short time and at low cost without using an adhesive or a tacker (stapler).

On the other hand, Patent Document 2 shows an example of a structure in which wrinkles and slack are prevented from occurring on the outer skin bonded to the outer periphery of the base material by using positioning pins and corresponding holes. According to this example, positioning holes are provided in the base material and the skin fused to the surface of the base material, while the counterpart material such as a cup holder that comes into contact with these from the skin side is provided with the positioning material. Positioning pins are provided at positions corresponding to the holes. And it is supposed that the wrinkles, slack, or peeling of the skin sandwiched between the base material and the mating material can be prevented by inserting the pin into the hole.
