Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the improvement of interior materials for automobiles, such as lining materials for automobile doors.

(Prior art) An automobile interior material in which a part of the base material is coated with a sheet-like skin material through a bed material and the remaining part is covered with a thick carpet-like skin material made of pile fabric has a decorative effect. However, in this type of automobile interior material, the elasticity of the loops of the carpet-like skin material made of pile fabric is strong, so the sheet-like skin material and the carpet have become very popular. Even if the strip-shaped skin material that connects the strip-shaped skin materials is attached using a retainer whose head is covered by the strip-shaped skin material, the pressing force is insufficient, the attachment is incomplete, and the finish of the connecting part is poor. There is a problem that the appearance of this part is damaged.

(Problems to be solved by the invention) The present invention eliminates the above-mentioned problems, and the elasticity of the first skin material with the bed material layer and the ring is strong, and the head is covered with the band-shaped skin material. When installed with a retainer, the strip skin material will come off.
An object of the present invention is to provide an interior material for an automobile in which the joining edge portion with the skin material can be appropriately and easily treated.

(Means for solving the problem) The automotive interior material of the present invention has a surface of the base material that is
and a second skin material whose joint side end is butted against the joint side end of the skin material, and a band-shaped skin material covering both joint side ends. In the automobile interior material in which the first skin material has a bed material layer on the back side, the joining side end portion thereof is formed into a thin-walled crushed portion in which a part of the bed material layer is crushed; The second skin material is made of carpet material, and a band-shaped skin material is sewn integrally with the joint side end of the second skin material with a folded edge formed on one side thereof. The folded edge formed on the other side of the band-shaped skin material is brought into contact with the joining side end of the skin material, and the pricking tool covered with the band-shaped skin material is used to connect the folded edge and the joint side end. It is characterized by being pressed and fixed to the base material.

(Example) Next, the present invention will be described in detail using the illustrated lining material of an automobile door as an example.

Reference numeral 1 denotes a base material made of hardboard, rigid fiberboard, etc., on the surface of which is laminated a bed material layer 6 such as polyurethane foam on the back side of the fabric such as vinyl chloride sheet or polyamide fiber woven fabric. and a second skin material 3 made of a carpet material such as pile material having countless loops and fluff. equipped. The edge of the joining side end portion 2a of the first skin material 2 is formed into a thin crushed portion 6a by heat pressure. Reference numeral 4 denotes a band-shaped skin material covering both joining side ends 2a, 3a, and this band-like skin material 4 is sewn with one side attached to the joining side end 3a of the second skin material 3 inside out. In addition, it is folded back so that the folded edge 4a is hidden. Then, this band-shaped skin material 4 covers the head 5a of the puncture tool 5, and the folded edge 4b formed on the other side is rolled up and interposed between the head 5a and the thin crushed portion 6a of the joining side end 2a, Sticking tool 5 on base material 1
It is pressed and fixed by sticking it to the. In the figure, 7 is an adhesive for attaching the bedclothes layer 6 to the base material 1 as required, and 8 is an adhesive for attaching the second skin material 3 to the base material 1 as required.

(Function) The device configured in this way is a hardboard,
The surface of a base material 1 such as a hard fiberboard is divided into a first skin material 2 made of a vinyl chloride sheet or a polyamide fiber woven fabric, and a second skin material 3 made of pile carpet fabric. In addition to being coated, the joining side ends 2a and 3a of both skin materials 2 and 3 are covered with a band-shaped skin material 4, so that the entire surface is covered with a type of skin material. It is similar to this type of conventional automobile interior material that it has a superior decorative effect compared to other materials, but according to the present invention, the band-shaped skin material 4 connecting the two skin materials 2 and 3 is The second skin material 3 has a folded edge 4a formed in
The folded edge 4b is integrally sewn to the joining side end 3a of the holder so that it does not come off, and the folded edge 4b is formed on the other side.
The folded edge 4b and the joint side end 2a are brought into contact with the joint side end 2a of the first skin material 2 by pricking the pricking tool 5 whose head 5a is covered with the strip-shaped skin material 4. Since it is fixed to the base material 1, only the linear recesses are exposed, and there are no visible edges 2a, 3a on both joining sides or any stitching marks, resulting in an extremely good finish and the strength of the connecting part. will also be excellent. However, in order to manufacture such automotive interior materials, it is necessary to prepare a second
The folded edge 4a on one side of the strip skin material 4 is connected to the joining side end 3a of the skin material 3 by sewing, and the cloth layer 6 and the first The skin material 2 is covered with a vacuum suction means etc., and then
The second skin material 3 is turned over and the folded edge 4b on the other side of the strip skin material 4 connected thereto is connected to the joining side end 2a.
The base material 1 is brought into contact with the folded edge portion 4b.
and finally fix the second skin material 3 with the pricking tool 5.
The remaining surface of the base material 1 is coated with the adhesive 8 if necessary by turning it over, and the end is tacked to the back end of the base material 1, so manufacturing is easy and inexpensive. can be provided to

(Effects of the invention) As is clear from the above description, the present invention is effective in concealing the joint edge of a carpeted skin material and another skin material, which easily comes off with a retainer due to the elastic force of the loops and fluff. The fixing process can be carried out accurately and easily, and it has great practical value as it solves the problems of conventional interior materials for automobiles of this type.
