BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, referring to FIGS. 1 and 2, each of the drawings illustrates a vehicle door lining as a vehicle interior material, and shows an enlarged wood grain groove portion of the door lining. In the figure, reference numeral R is a lining substrate, W is a wood grain groove, and 10 is a first that covers the entire surface of the lining substrate R.
(Hereinafter, simply referred to as "surface material"), reference numeral 20 denotes a second surface material (hereinafter referred to as "center pad") attached as a center pad or the like.

The lining substrate R is polypropylene, A
It is made of synthetic resin such as BS resin or wood mat. When the lining substrate R is formed, the wood grain groove W is formed as a concave groove portion whose plane shows a predetermined continuous curve.

The covering material 10 is made of polyvinyl chloride leather 10a, which covers the entire surface of the lining substrate R.
Polypropylene foam 10b laminated material or TPO,
The substrate surface is adhered by vacuum die molding by using a laminated material of PVC or the like. Along with the attachment of the cover material 10, the surface portion is recessed into the wood grain groove W, but the recessed portion 11 is formed so that the internal space S remains on the bottom side of the wood grain groove W. There is.

After the covering material 10 is applied to the plate surface of the lining substrate R, a notch 12 is made in the indented portion 11 by an automatic cutter or an ultrasonic cutter, so that the bottom is incised inside the wood grain groove W. . The cut 12 is preferably formed by inserting the end of the center pad 2 into the inner space 3 of the wood-cutting groove W and inserting the bottom of the recessed portion 10 into a linear shape so that the thickness of the end can be held, as will be described later. .

As the center pad 20, a laminated material of polyvinyl chloride leather 20a and urethane slab 20b can be used. The center pad 20 is adhered and fixed by compression molding using a mold by applying an adhesive to the back surface or the front surface side of the facing material 10. Further, the inside of the surface is adhered to the surface of the cover material 10, and the remaining end 21 is pressed into the inside of the recessed portion 11 of the cover material 10 with a pushing bar so that the end 21 is cut from the cut 12 of the recessed portion 11 to the wood grain. It is inserted and fixed even in the internal space S of the groove W.

Thus, the terminal 21 of the center pad 2
When the center pad 20 is inserted into the internal space S of the wood-groove W, even if the set position of the center pad 20 is uneven or misaligned, the remaining width of the terminal 21 can be entirely inserted into the internal space S. It is possible to reliably prevent the terminal 21 from protruding to the surface side of the cover material 10. In particular, even when a center pad formed of a skin material such as a soft leather or a knitted fabric having a large elongation rate is attached, the entire area including the elongation amount can be inserted into the internal space S, so that the end of the center pad is grooved. It is possible to prevent the appearance defect due to the protrusion in the periphery and reduce the occurrence of the defect rate.

If the notch 12 is provided in a linear shape, the thickness of the center pad 20 including the urethane slab 20b can be held, so that the terminal 21 can be securely fixed and fixed. Further, since the end 21 of the center pad 2 is placed in the internal space S of the wood grain groove W and the end 21 is not overlapped with the recessed portion 11 of the covering material 10, the wood grain groove W should be formed with a narrow groove width. You can Therefore, by pressing the end 21 of the center pad 20 into the narrow recessed portion 11, the recessed portion 11 of the covering material 1 can be embedded so as not to be seen from the outside.

In addition, the indented portion 11 of the facing material 10
When the bottom side is curved in a U shape, the end 21 of the center pad 20 can be more firmly held by the notch 12 of the indented portion 11, and the urethane slab 20b of the center pad 20 can be swelled to hold the end. can do. Therefore, even if the recessed portion 11 of the facing material 10 is formed shallow, the recessed portion 11 can be embedded so that the inside cannot be seen from the outside.

Although the above-described embodiment has been described with respect to the case where the center pad is attached to the door lining, the center pad is attached to the body side lining, and the pad members other than the center pad are used for the door lining and the door lining. The same can be applied to the body side lining, the rear tray, etc., and further, the sheet member other than the pad member can be attached with wood grain.

[0020]

As described above, according to the terminal wood-grained covering structure of the cover material according to the first aspect of the present invention, even if the position of the second cover material is varied or misaligned when setting the second cover material. ,
Since the end width of the cover material is inserted from the recessed portion of the first cover material to the inner space of the wood grain groove, the end width of the second cover material is more than that of the recessed portion of the first cover material. It surely prevents it from protruding to the side. Therefore, it is possible to form a good appearance around the wood grain groove and prevent the occurrence of a defective rate.
It is also possible to easily carry out the work of depositing the covering material including the positioning of the covering material set.

According to the terminal wood grain adherence structure of the covering material according to the second aspect of the present invention, the notch of the bottom portion of the second covering material is formed in a U-shaped curved bottom portion of the thickness of the second covering material. Since it can be swollen and securely held by, the embedding and fastening can be performed at the end of the second cover material so that the inside cannot be seen even if the indented portion of the first cover material is shallow.
