Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a tensioning structure for a seat cover.

(Prior Art) Conventionally, for example, as shown in FIG. 7, in the case of a seat bag 1 having a shape in which both sides of the backrest are raised, the seat cover 7 has been cut to follow the shape and sewn together. is installed. The seat cover 7 of the raised portion 2 has a tension structure in which the seam portion 8 of the seat cover 7 is pulled inward of the seat pad 5, so that it can maintain a predetermined shape. This conventional tensile structure
As shown in FIG. 9 and FIG. 9, a hanging cloth 21 in which a cloth body is sewn into a cylindrical shape is provided on the seam portion 8 of the seat cover 7,
A rubber tension rubber body 2 is placed inside the cylinder of this hanging cloth 21.
2, the tension rubber body 22 is arranged so as to pull the suspension cloth 21 inward to the seat pad 5, and both ends of the tension rubber body 22 are fixed to the frame of the seat back 1, etc. in a tension manner, and the seam portion of the seat cover 7 is secured. 8 is formed to follow the shape of the seat pad 5.

(Problem to be solved by the invention) However, the conventional tensile structure described above,
Since the hanging cloth and the tension rubber body are loosely inserted, there is a problem in that the surface of the seat cover is wrinkled due to the difference in the retracting load at the end of the hanging cloth.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a tension structure for a seat cover that prevents wrinkles from occurring on the surface of the seat cover due to strain even if the seat cover is subjected to a difference in retraction load.

(Means for Solving the Problems) The means of the present invention to achieve the above object is to pull the seam part of the seat cover inwardly of the seat and hold the seat cover part near the seam part in close contact with the seat pad. The structure is such that the insertion groove of the seat pad that accommodates the seam on the back of the seat cover is equipped with a tension rubber band consisting of an elongated tension rubber body and a band-shaped hanging rubber band integrally molded in the longitudinal direction of the tension rubber body. A tension member is arranged, a hanging rubber band is sewn to the seam part, and the hanging rubber band is pulled inward and both ends of the tension rubber body are connected in a tension manner to the frame of the seat or reinforcing wire. It is considered to be a structure.

(Function) The seam portion of the seat cover is constantly kept in tension inward by a tension rubber body via a hanging rubber band. The hanging rubber band has elasticity and can tolerate a difference in retracting load on the tension rubber body.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 6.

As shown in FIG.
The inserted seat pad 5 and the seat cover 7
It is mainly formed by In the seat bag 1 employing a tension structure, a seat cover 7 which has been previously cut and sewn is stretched over a seat pad 5 so as to follow the shape of the raised portions 2 on both front sides of the seat bag 1. Sewing portion 8 of seat cover 7
An insertion groove 6 for a seam portion 8 is provided in a portion of the seat pad 5 corresponding to the seat pad 5 . The suture portion 8 is tensioned into the insertion groove 6 via a tension member 9. As shown in FIGS. 3 and 4, the tension member 9 of this example includes an elongated tension rubber body 10 whose both ends are fixed to the reinforcing wire 4 or the frame, and a band-shaped tension rubber body 10 integrally molded on the sides thereof. It consists of a hanging rubber band 11. Note that the tension rubber body 10 is made into an elongated shape that is thicker than the suspension rubber band 11, and both end portions serving as stopper portions protrude outward from the suspension rubber band 11.

The tension member 9 is made into a single member in which a tension rubber body 10 and a suspension rubber band 11 are integrally molded by molding soft rubber or relatively soft rubber. A retaining ring 1 is attached to one end of the tension rubber body 10.
2 is attached, and a stop portion 14 of a hog ring 13 is provided on the other end side. When assembling the seat cover 7, the end side 11A of the hanging rubber band 11 of the tension member 9 is sewn along the sewn portion 8 of the seat cover 7 (sewn portion 15). The sewing part 15 on the end side 11A of the hanging rubber band 11 may be performed at the same time as the sewing part 8 of the seat cover 7 is formed.

Thus, the hanging rubber band 11 is made into a tensioned state, and the tensioning rubber body 10 is placed in the insertion groove 6, and the retaining ring 12 of the tensioning rubber body 10 is attached to the hog ring 13.
It is fixed to the frame (or wire) via a hog ring 13 to the stopper part 14 at the other end of the tension rubber body 10, and is fixed to the frame (or wire) in a tension state that is stronger than the tension state of the hanging rubber band 11. It will be worn. By fixing the tension rubber body 10 in the insertion groove 6, the seam part 8 of the seat cover 7 is pulled into the insertion groove 6 via the hanging rubber band 11, and the seam part 8 is in the vicinity of the seam part 8. The seat cover 7 portion is closely held along the shape of the seat pad 5 (see FIG. 6).

Therefore, the tensile structure of the seat cover 7 of this example was able to produce a beautiful finish without causing wrinkles in the tensioned portion of the seam portion 8 during assembly.

(Effects of the invention) The present invention has an elongated tension rubber body and a band-shaped hanging rubber band integrally molded in the longitudinal direction of the tension rubber body in the insertion groove of the seat pad that accommodates the seam on the back surface of the seat cover. A tension member consisting of is arranged, a hanging rubber band is sewn to the seam part, and the hanging rubber band is pulled inward to connect both ends of the tension rubber body to the frame of the seat or reinforcing wire in a tension state. Because of this structure, the seam portion of the seat cover is always pulled inward, and the vicinity of the seam portion of the seat cover can be well maintained in a shape along the seat pad.

Since the present invention uses a tension member consisting of an elongated tension rubber body and a belt-shaped suspension rubber band integrally molded in the longitudinal direction of the tension rubber body,
The seat cover is easier to assemble than the conventional two-part case, which consists of a cylindrical hanging cloth and a tension rubber inserted through it. Wrinkles do not occur on the surface due to the stretching of the band.
