DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for a vehicle interior such as an instrument panel, a door trim, and a seat for a vehicle, a sewing method of the cover, and a vehicle interior provided with the cover.

[0002]

2. Description of the Related Art A conventional example will be described. Here, an instrument panel as an interior part for a vehicle will be exemplified. FIG. 7 is an exploded partial perspective view of the instrument panel.
In the instrument panel, the resin base material 1
Reference numeral 10 denotes a leather-wound type covered with a genuine leather cover 120. In addition, the base material 110 is equivalent to the inside member referred to in this specification.

The cover 120 has a single stitch as a design. A method of sewing the cover 120 will be described with reference to partial perspective views of FIGS. First, as a first step, as shown in FIG.
The two skin materials 121 and 122 are sewn together by splitting (see seam 123). Next, as a second step,
As shown in FIG. 9, the seam allowances 121 a and 122 a of the outer skin materials 121 and 122 are turned back. Next, as a third step, as shown in FIG.
A single stitch 122b is applied to the skin materials 121 and 122 by face-down sewing (see the seam 124). The face-down sewing is disclosed in JIS B9003 No. 336.

[0004]

However, in the cover 120 of the above-described conventional example, as shown in FIG. 10, the overlap in the single stitch is a total of three sheets including the lower skin material 122 and both the seam allowances 121a and 122a. become. Therefore, when the shape near the seam 123 of the seam of the two skin materials 121 and 122 becomes slack, a phenomenon that the seam of the seam of the seam, that is, the sewing line 125 undulates like a wave, that is, a so-called “sag” is easily generated ( (See FIG. 7). The cover 120 is attached to the base 110 of the instrument panel with reference to the sewing line 125 (see FIG. 7). However, as described above, if the “slip” occurs on the sewing line 125, it becomes very difficult to understand the standard for attachment. Further, it is difficult to properly attach the sewing line 125 while correcting the "slip".

The following sewing methods 1 to 3 (see the partial perspective views in FIGS. 11 to 13) can be considered in addition to the above-mentioned conventional example, but are not preferable for the following reasons. The sewing method 1 shown in FIG. 11 is a method in which both the seam allowances 121a and 122a are reversed, the inner seam allowance 122a is cut off by a predetermined amount, and the outer seam allowance 121a is sewn to perform a single stitch (JIS terminology). B9003
No. 336). However, both seams 123, 124
Since the number of overlaps is three in total, there is a problem similar to that of the above-described conventional example. 11 to 13, the same parts as those in the conventional example are denoted by the same reference numerals. Further, the sewing method 2 shown in FIG.
This is a method of performing a single stitch by sewing one skin material 122 alone without sewing the 122a. However, the rigidity of the peripheral portions of the both seams 123 and 124 is insufficient, so that “sags” easily occur on the sewing line 125, wrinkles 126 are likely to move due to the tightening of the thread of the seams 124, and furthermore, the two seams 123 and 124 There are problems such as a loss of the three-dimensional effect in the peripheral portion. Further, the sewing method 3 shown in FIG.
a, 122a are divided into upper and lower portions, and the respective seam allowances 121a, 122
a is individually sewn to perform double stitching (JIS 900 B900).
3 No. 338). However, with double stitching,
There is a problem that design needs are low.
