BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat cover characterized by a hanging cloth sewn to the back surface of a cover body.

[0002]

2. Description of the Related Art In a vehicle seat cover, a hanging material is sewn to the back surface of a cover body with a sewing allowance, and a core material such as a wire is inserted through a core material insertion portion formed in the cover body. It is normal to insert a hanging cloth together with this core material into a cushion body and hold the seat shape by hanging it on a seat frame with a hog ring or the like. As shown in Japanese Utility Model Application Laid-Open No. 56-108799, the material insertion portion is formed by folding the belt in the longitudinal direction to form a bag-shaped core material insertion portion on the folded side and sewing the other side. As shown in FIG. 7, the core material 32 freely moves around in the hanging cloth 31 as shown in FIG. 7, so that the core material 32 falls off or is inclined obliquely. That Ri, As a result, hog rings 33
In addition to the above, there is a problem that the work of suspending and binding to the seat frame 34 becomes difficult, and the hanging cloth 31 is pulled too deeply to cause wrinkles on the design surface of the seat.

[0003] To prevent this, measures such as using a tack pin 35 to accurately bond the two at a predetermined position, and using a hanging thin plate made of a synthetic resin have been studied. In addition, there is a problem that the cost is significantly increased. On the other hand, as shown in Japanese Utility Model Application Laid-Open No. 61-45892, a means for fixing a wire with an adhesive so as to prevent the wire from freely moving around has been proposed, but the workability is poor and the production cost is high. There was a problem of becoming.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, and prevents the wire from freely moving around in the hanging cloth, and prevents the wire from being connected to the frame by the hog ring. Providing a vehicle seat that can be performed accurately at a proper position, and the seat cover is securely hung at a predetermined position with respect to the cushion body, has an excellent appearance without wrinkles, and has excellent productivity and low production cost. It was completed for the purpose of a possible vehicle seat cover.

Such a vehicle seat cover is covered with a cushion placed on a seat frame, and then the hanging cloth is connected to the seat frame by a hog ring through the cushion to be retracted. The cover is attached to the surface of the cushion body in a state having a shape maintaining function exactly as in the case of the conventional vehicle seat, but before covering the cushion body, the core material is made of the hanging cloth. And a back cloth portion of a close core material insertion portion formed between a first stitching line and a second stitching line for stitching the front cloth portion and a back cloth portion overlapped therewith. Since the core material is inserted and sandwiched therebetween, the core material does not fall off, rotate, or tilt.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment in which the present invention is applied to the illustrated automobile seat will be described in detail as an embodiment. In the drawing, reference numeral 1 denotes a vehicle seat cover according to the present invention. The vehicle seat cover 1 is provided on a back surface of a cover body 2 sewn with a laminated skin material in which a slab urethane laminate layer is formed on the back surface of a skin material. A hanging cloth 4 is integrally sewn to the remaining stitching projection with a sewing allowance 3 at the upper end. The hanging cloth 4 of the embodiment is obtained by folding a single band cloth into two parts, and
a back cloth portion 4b is superimposed on the intermediate portion between the superposed back cloth portion 4a and the back cloth portion 4b and a portion close to the folded edge by a sewing machine, a welding process, an adhesive, or any other means.
The front and back cloth portions 4a and 4b are stitched together by forming the suture line 5 and the second suture line 6 to form a tightly inserted core material insertion portion 7 between the two suture lines 5 and 6. The edge opposite to the folded edge is a sewing allowance 3, and the close core material insertion portion 7 has a U-shape at both ends of the wire that is 3 to 10 mm narrower than the width of the close core material insertion portion 7. The core material 8 having the bent portion 8a formed therein is inserted through the core material 8 and the front cloth portion 4a and the back cloth portion 4b.
It is one that is sandwiched between.

The two sewn portions 5 and 6 are for forming a close core material insertion portion 7 between the front cloth portion 4a and the back cloth portion 4b. 6 has a function of preventing the gap between the bag-shaped core material insertion portions, which are merely folded back, because the mutual interval is automatically opened. On the other hand, the first suturing portion 5 has the function of the close core material insertion portion 7. The width is defined to be slightly wider than the maximum width of the core material 8. In an embodiment in which the wire is the core material 8, the close contact formed between the first suture line 5 and the second suture line 6 is provided. The width of the core material insertion portion 7 is 3 to 10 mm larger than the maximum width of the core material 8 and the close core material insertion portion 7
Although there is no problem in inserting the core material 8 therein, the core material 8 is prevented from freely moving around in the hanging cloth 1 after the insertion. This is because when the width of the close core material insertion portion 7 formed between the suture lines 5 and 6 is smaller than the maximum width of the core material 3 by 3 mm or more, it becomes difficult to insert the core material 8 into the close core material insertion portion 7. If it is larger than 10 mm, it is difficult to reliably prevent the rotation of the core 8 when the core 8 is made of a circular cross section such as a wire.

Although the embodiment has been described with respect to the hanging cloth 4 in which one band cloth is folded in the center at two places,
As shown in FIG. 4 and FIG. 5, two core cloths may be overlapped to form the close core material insertion portion 7 by the first suture line 5 and the second suture line 6. When the position of the first suture line 5 coincides with the sewn portion 9 between the hanging cloth 1 and the cover main body 2, the sewn portion 9 is left as it is without providing the first sewn line 5 in advance. It may be used as the first suture line 5. Further, in the embodiment, the hanging cloth 1 is described by folding one band cloth at the center, but as shown in FIG. 4 and FIG. The close core material insertion portion 7 may be formed by the suture line 5 and the second suture line 6.

[0010] With the above structure, the cover body 2 is attached to the cushion body 12 placed on the seat frame 11.
The hanging cloth 4 sewn and integrated with the sewing allowance 3 on the back surface thereof is drawn into the seat frame 11 through a slit formed in the cushion body 12, and the core material 8 is formed.
When the closely inserted core material insertion portion 7 through which is inserted is attached to the seat frame 11 by a hog ring 13, the cover body 2 fits exactly on the surface of the cushion body 12 by the shape retaining function of the pulled-in hanging cloth 4. The first suturing, in which the core material 8 is sewn and integrated with the front cloth portion 4a and the back cloth portion 4b of the hanging cloth 4 before the cushion body 2 is covered, The surface of the close core material insertion portion 7 which is inserted into the close core material insertion portion 7 formed between the line 5 and the second suture line 6 and which is not subjected to a force in a direction in which the mutual interval is always widened. Since the core material 8 is held between the cloth portion 4a and the back cloth portion 4b with a frictional force, the core material 8 does not fall off, so that the core material 8 is not only stored and transported but also when the cover body 2 is covered with the cushion body 12. No need to worry about falling off It without the core 8 or tilted or rotated in the wood insertion portion 7, so that the binder of the seat frame 11 by hog rings 12 is performed accurately at a predetermined position.

[0011]

As is clear from the above description, according to the present invention, the core material is reliably prevented from falling off and freely moving around in the hanging cloth, so that the binding with the seat frame by the hog ring is performed at a predetermined position. The cover body is securely hung at a predetermined position with respect to the cushion body, and has an excellent appearance without wrinkles. Accordingly, the present invention has solved the problems of the conventional vehicle seat cover, and has advantages that the structure is simple, the productivity is excellent, and the production cost is low, contributing to industrial development. Is extremely large.
