However, each of the door 1-rims made by these methods has advantages and disadvantages.

First, in the case shown in FIG. 1, since the boundary between the skin materials 4 and 4' is simply separated by a welded part, a so-called cut edge can be seen at the edge of the joint surface.

Therefore, a door trim with this structure does not look good, and depending on the type of skin material, there are some materials that cannot be subjected to high-frequency welding, so there are restrictions on the materials used.

Next, the door trim shown in FIG. 2 has a good appearance and there are no restrictions on the material. However, the skin material 4 on the board core material 1 side can be integrated by high-frequency welding, but the pad material 3-2 on the garnish 2 side and the skin material 4 on the garnish 2 side can be integrated by garnishing.
Nitori (J Riruru) has to be done with a different attachment method such as vacuum attachment means, and the extra man-hours increase the cost of the same 11M (, L 11.). I!IJ construction cost is high.

(Object of the Invention) This invention provides the same appearance performance as the conventional two-part type door 1 to rim as shown in FIG.
The purpose is to make it easy and inexpensive to manufacture.

(Structure and Effect of the Invention) In order to achieve the above object, the skin material on the garnish side constituting the door 1 to the rim for a 1Jll car of the present invention is attached to the board core material above the joining position of the garnish. In addition, the lower part of the board is sandwiched between the joint between the board core material and the garnish, and the board is folded back and bonded to the surface of the garnish using this joint as a starting point.

In addition, in order to improve the above structure by 1q, the method of the present invention includes a step of bonding the skin material to the surface of the board core material, and aligning the upper edge of the skin material on the garnish side with the upper edge of the board core material. and fix the garnish to the board core material,
A process of clamping and fixing the garnish side skin material between the lower edge and the board core material, folding the skin material back from this fixed end as a base point, pasting it on the garnish surface, and attaching the wrapped end of the back side to the garnish. It is characterized by the process of rolling it into the back side and fixing it.

According to the above structure, the product appearance F can be obtained which is exactly the same as the conventional one shown in FIG. Because it can be digitized, it has various advantages such as reducing the number of man-hours and the unit price per product.
