Abstract

(57) [Summary] [PROBLEMS] To provide a seat cover which is excellent in design and can obtain excellent sitting comfort without a feeling of foreign matter. SOLUTION: A part of the seat cover material 1 is drawn into a seat pad on the back side of a seat cover material 1 in which a wadding material 3 is superimposed on the back surface of a skin material 2 to form a design line in an intermediate portion of the seat cover material 1. Valley-shaped concave portion 21 serving as a design line is formed by sewn a seam allowance 4 which is bent by superposing the surfaces of the skin material 2 on the front side of the wadding material 3 in the seat cover in which the hanging bag 12 for sewing is integrally formed. At the same time, the hanging bag 12 is sewn on the back side of the seat cover material 1 by sewing a hanging bag sewing allowance 5 attached to the back side of the wading material 3 to the skin sewing allowance 4 through the wadding material 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat cover which is excellent in design and can provide excellent sitting comfort without a feeling of foreign matter.

[0002]

2. Description of the Related Art Conventionally, as a retracting structure of a seat cover in an automobile seat or the like, for example, a conventional Japanese Utility Model Laid-Open Publication No.
As shown in Japanese Patent Publication No. 1600, the ends of two sheet covers in which a skin material and a wadding material are laminated are sewn, and a hanging bag is further sewn to the sewn portion, and the hanging bag is drawn into a recess of a pad. It is widely known that a design line is formed by using the above.

[0003] However, in the conventional device, the design line is formed by overlapping the seat cover, and the wadding material is compressed and solidified at the sewn portion. There was a problem that would. In addition, there is also a problem that the stitching portion extends in the vertical direction, thereby deteriorating the deflection of the stitching portion and hindering sitting comfort. It was remarkable.

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, and can form a clear design line, exhibit excellent design properties, and form a design line. The present invention has been completed with the object of providing a seat cover in which the overlap of the sewn portions is minimal, the wadding material is not compressed, and an excellent sitting comfort without any foreign body feeling can be obtained.

[0005]

Means for Solving the Problems A seat cover according to the present invention which has been made to solve the above-mentioned problems, comprises a part of the seat cover material on the back side of a seat cover material in which a wadding material is overlapped on the back surface of a skin material. In a seat cover that is integrated with a hanging bag for forming a design line in the middle of the seat cover material by pulling it into the seat pad, the valley-shaped concave part that becomes the design line The hanging bag is formed by sewn the overlapped seam allowance, and the hanging bag is sewn to the skin seam allowance through the wadding material along with the hanging bag seam allowance attached to the back side of the wading material, and integrally sewn on the back surface of the seat cover material. It is characterized in that it is

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. The drawings show a case where the present invention is applied to an automobile seat 20. In the drawings, reference numeral 1 denotes a seat cover material in which a wadding material 3 is superimposed on the back surface of a skin material 2, 10 denotes a pad of a seat cushion, and 11 denotes a seat cover. The recesses 12 for drawing in are sewn on the back side of the seat cover material 1 so that a part of the seat cover material 1 is drawn into a seat pad and a valley-shaped recess 21 serving as a design line is formed in an intermediate portion of the seat cover material 1. It is a hanging bag integrated with
This type of conventional seat cover is that the hanging bag 12 is fixed to the wire 14 by the C-ring 13 and the seat cover 1 is drawn into the concave portion 11 of the pad 10 to form a design line in the middle of the seat cover material 1. And basically the same.
Reference numeral 15 denotes a wire inserted into the hanging bag 12.

In the present invention, the valley-shaped concave portion 21 serving as the design line is formed by sewing a skin seam allowance 4 which is formed by overlapping the surfaces of the skin material 2 on the front side of the wadding material 3 and is bent. Reference numeral 12 is characterized in that a hanging bag sewing allowance 5 attached to the back side of the wadding material 3 is sewn to the skin sewing allowance 4 through the wadding material 3 and is sewn and integrated on the back side of the seat cover material 1.

More specifically, such a structure will be described. In FIG. 1, the skin material 2 is divided into left and right divided skin materials 2.
a folded end portion 4a of the other divided skin material 2b is sewn and integrated with a sewing line 6a on the end surface of one of the divided skin materials 2a. The sewing line 6a is sewn together with the skin sewing allowance 4. In FIG. 2, the skin material 2 is composed of left and right divided skin materials 2a and 2b, and the folded portions of the folded ends 4a and 4b at both ends are integrally sewn together by a sewing line 6c. The hanging bag sewing allowance 5 is sewn to the skin sewing allowance 4 by a hanging bag exclusive sewing line 6d different from the sewing line 6c. Also, in FIG. 3, the skin material 2 is one sheet, and the
Are formed by folding the intermediate surfaces of the skin material 2 on top of each other, and are sewn together by the same sewing line 6e as the hanging bag sewing allowance 5.

In the seat cover shown in FIG. 1, for example, one skin material 2a is placed at an arbitrary position on the wadding material 3 and sewn with a sewing thread 6b, and then the other skin material 2b. The folded end 4a is sewn together with the wadding material 3 and the hanging bag 12 by a sewing line 6a to form a valley-shaped concave portion 21 serving as a design line. Therefore, the valley-shaped recess 2 forming this design line
1 is constructed by only bending the second skin material 2b, so that there is no overlapping portion of the wadding material 3 as in the conventional case, and excellent sitting comfort without any foreign object feeling is exhibited. Since there is room in the bent portion of 2b, a sufficient deflection is secured.

In the above-described structure, a valley-shaped concave portion 21 serving as a design line is formed by sewing a skin seam allowance 4 which is bent by superposing the surfaces of the skin material 2 on the front side of the wadding material 3 and The hanging bag 12 is sewn on the back side of the seat cover material 1 by sewing the hanging bag seam allowance 5 attached to the back side of the wadding material 3 to the skin sewing allowance 4 through the wadding material 3, so that it is sewn integrally. There is no overlapping portion of the wadding material 3 at all, and the overlapping portion is only the folded portion of the skin material 2, so that an excellent sitting comfort without any foreign object feeling can be obtained. In addition, a sharp design line is formed by folding the skin material 2.
Further, the sewing operation can be easily performed by simple sewing, and mass production can be performed at low cost. Furthermore, since there is room in the bent portion of the skin material 2, a sufficient deflection can be secured.

[0011]

As is clear from the above description, the present invention can form a clear design line and exhibit excellent design properties, and minimize the overlap of the stitching portions forming the design line. In addition, the wadding material is not compressed, so that excellent sitting comfort without any foreign body sensation can be obtained. Therefore, the present invention greatly contributes to industrial development as a seat cover that has eliminated the conventional problems.
