Description

[Detailed description of the invention] [Industrial field of application] This invention moves the surface material of a sheet in the direction of elastic wires bridged by a frame that is positioned with a cushioning material interposed between the surface material and the surface material. Regarding the pulling structure for pulling.

[Conventional technology]

For example, each side a1, a of the main part a of the surface material of the seat part A of a vehicle seat and the main part b of the surface material of the back part B of a vehicle seat as shown in FIG.
The portions along lines 2, a3, b1, b2, and b3 are drawn toward the bottom side of the sheet portion A and the rear side of the back portion B to prevent the surface layer material from lifting up.

The above-mentioned pulling structure is shown in FIG. 4, which is an enlarged cross-sectional view of FIG. 3. In this figure, 1 is the surface material of the back part, 2 is an inverted U-shaped frame located on the rear side of the back part, 3 is an elastic wire bridged between the frames 2, and 4 is the surface material 1. The cushioning material 5 held between the covered surface material 1 and the elastic wires 3, 3, .
A bag formed by double folding, 5a is the end of the bag 5 attached to the back side 1a of the surface material 1, 6 is a hard wire inserted into the bag 5, and 7 is the hard wire 6 connected to the elastic wire. This is an ohm clip for stopping the wire.

Then, a suitable number of ohm clips 7, 7, . .

(Problems to be Solved by the Invention) The conventional bag body 5 has no mark indicating the position where the ohm clip is to be stopped, and the position of the hard wire 3 cannot be visually checked. The clip 7 may be penetrated deep into the bag body 5, that is, with a gap 8 created between the hard wire 6 and the ohm clip 7. At this time, stress is concentrated at the part of the bag body through which the ohm clip passes, and the bag The body may be torn or wrinkles 9 may occur on the surface of the surface material 1. Also, since there are no marks, multiple ohm clips may be stopped by leaning to one side as shown in Figure 7. , the surface layer material 1 is not pulled on the other side opposite to the one side, causing the surface layer material to float.

As mentioned above, conventional pulling structures have the disadvantage that they can result in sheets that are unattractive.

The purpose of this invention is to eliminate the above-mentioned drawbacks and provide a drawing structure for the surface layer material that always provides a sheet with a good appearance in the drawn area.

[Means for solving problems]

In order to achieve the above-mentioned purpose, the pulling structure of this invention is attached as a bag by folding a long sheet in double from the center and sewing the both ends to the back side of the surface material. It has a structure made of a fabric that is braided so that the part through which the clip is inserted is coarse and the other part is densely braided.

[Effect]

Since the bag in the pulling structure of this invention has the above-mentioned configuration, the ohm clip is positioned at a predetermined location by inserting the ohm clip into the rough part of the bag that serves as a mark.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a bag according to an embodiment of the invention attached to an elastic wire, and FIG. 2 is a developed view of the bag shown in FIG. 1.

The bag 11 of this embodiment is made of a long sheet 11a of fabric that is braided so that it has coarse parts 12a, 12a symmetrically spaced a certain distance from the center line a-a, and the other parts are dense parts. It is attached by folding it twice from the center line a-a and sewing its ends 13 and 14 to the back side of the surface material.

The above-mentioned dense portions are, in more detail, the dense portion 15 on the hard wire 6 side, the dense portion 16 on the both ends 13 and 14 side sewn to the surface material, the dense portion 15 on the hard wire 6 side and the both ends 1
Connecting dense portion 18 that connects the dense portion 16 on the 3 and 14 sides
It consists of

As mentioned above, the bag body 11, which is folded twice and attached to the surface material, has rough parts 12a and 12b overlapping each other, and an ohm clip is used to connect both the rough parts 12a and 12b.
By inserting the wires a and 12b and connecting the hard wire 6 and the elastic wire 3, the ohm clip is positioned at a predetermined location, and the bag body 11, and therefore the surface material, are not lifted up. You can pull it. In addition, in the example, the rough part in the pulling direction of the bag is 1
Although only one location is used, two or more locations may be used.

〔effect〕

The pulling structure of the surface material of this invention can be used as a bag body.
A long sheet was folded double from the center and attached by sewing both edges to the back of the surface material, and the long sheet was braided so that the part where the clip was inserted was coarse and the other parts were dense. Since the bag is made of woven fabric, inserting the clip through the rough part ensures that the clip is in the specified position, and the rough part allows for flexibility in misalignment, so there is no wrinkles in the bag. Moreover, it is a strong bag that does not fray, and has the effect of being able to pull the surface layer material uniformly without stretching in the direction of the elastic line.

Claims (1)

[Claim for Utility Model Registration] A bag body with hard wires is attached to the back side of the surface material covering the surface of the cushioning material, and the hard wires of the bag body and the elastic wires bridged by the frame are secured so as to surround them. In the pulling structure of the surface material, in which the bag body is pulled by a clip that is attached to the surface material, the bag body is attached by folding a long piece of sheet double from the center and sewing both edges of the sheet to the back side of the surface material; This long sheet is made of a fabric that is braided so that the part where the clip is inserted is coarse and the other part is densely braided.
