[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover fixing member used for fixing a vehicle seat cover to a frame or the like of a seat body.

[0002]

2. Description of the Related Art Conventionally, when a seat cover is mounted on a seat body of a vehicle seat, an end of the seat cover is fixed by hogling to a reinforcing wire or a frame of the seat body. In this case, the end of the seat cover is fixed in a state of being pulled by a frame or the like via a wire for hog ring. For this reason, if the end of the seat cover is simply hogled, the seat cover may be broken from the hog ring location. Therefore, a reinforcing wire is sewn in advance to the end of the seat cover, and the end of the seat cover to which the wire is sewn is hogled to prevent the seat cover from being broken.

However, if the wire is sewn into the seat cover, the wire must be extracted when the sheet is discarded or reused, which requires a lot of work.

Therefore, recently, a fixing member 1 shown in FIG. 5 has been used in place of the wire. The fixing member 1 includes a thin plate-shaped portion 11 and a thick head 12 formed along one side portion of the plate-shaped portion 11 extending in the longitudinal direction, and forms a sheet. The whole is integrally formed of the same resin as the resin.

When the seat cover is mounted on the seat body using the fixing member 1, the side of the plate-like portion 11 opposite to the head 12 is attached to the end of the seat cover S as shown in FIG. And the side of the head 12 side is hogled to the reinforcing wire W or the frame F by the wire T. In this case, the plate-like portion 11 has a small thickness and is flexible. On the other hand, since the head 12 has a large thickness and an appropriate strength, it prevents the fixing member 1 from breaking from the hog ring portion. In addition, in FIG. 4, the code | symbol P is a seat pad.

[0006]

The fixing member 1 is usually formed by an injection molding method, an extrusion molding method or the like. For example, when molding by an injection molding method, a cavity having the same cross-sectional shape as the fixing member 1 is formed in a mold, and the cavity is filled with resin. However, when molding in this way,
Since the width of the portion corresponding to the plate-shaped portion 11 of the cavity and the portion corresponding to the head 12 are greatly different, the narrow portion corresponding to the plate-shaped portion 11 is not sufficiently filled with the resin, and 11 could not be formed into a desired shape.

The present invention has been made to solve the above problem, and has as its object to provide a cover fixing member which can form a thin plate-like portion into a desired shape.

[0008]

According to the present invention, in order to achieve the above-mentioned object, at least a thin plate-shaped portion, which is formed entirely of a resin, and which is integrally formed on one side of the plate-shaped portion, is provided. A groove extending along the longitudinal direction of the head on a side surface of the cover opposite to the plate-like portion side, the cover-fixing member including a head having a plate-like portion-side portion having a thickness greater than that of the plate-like portion; A fixing member for a cover, wherein a fixing member is formed. In this case, it is desirable to form an elongated hole in the plate-shaped portion near the head with the longitudinal direction directed to the longitudinal direction of the plate-shaped portion.

[0009]

The head is divided into a plurality of parts by grooves. As a result, the thickness of the entire head is constant, but the thickness of each portion divided by the groove is reduced, and the thickness can be made approximately the same as that of the plate portion. Therefore, in a mold for molding the fixing member, the difference in width between the respective portions of the cavity is reduced.

[0010]

1 to 3 show an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 shows a fixing member 2 for a cover according to the present invention. The fixing member 2 differs from the conventional fixing member 1 in that a groove 13 is formed in a head 12. That is, the head 12 has the plate-shaped portion 1
A groove 13 having a rectangular cross section is formed at the center of the side surface opposite to 1. The depth of the groove 13 is the width W of the head 12.
It is shallower.

By forming the groove 13, the head 12
Are a base 12a on the plate-like portion 11 side, and a pair of upright portions 12b and 12c which respectively stand from both sides of the base 12a.
Is divided into The width t1 of the base portion 12a and the upright portion 12
Each of the thicknesses t2 and t3 of b and 12c is substantially equal to the thickness T of the plate-shaped portion 11. Moreover, since the depth of the groove 13 is smaller than the width W of the head 12, the base 12a
2 (= t2 + width of groove 13 + t3), which is thicker than plate-like portion 11.

The fixing member 2 having the above structure is used in the same manner as the conventional fixing member 1 (see FIG. 4). Therefore, when the portion near the head 12 of the plate-shaped portion 11 is hogled, the head 1
2, a force F acts in the direction of the arrow. At this time, the width W of the head 12 in the direction in which the force F acts is constant regardless of the presence or absence of the groove 13. Therefore, force F in the direction of arrow F
The strength of the head 12 with respect to is hardly reduced even if the groove 13 is formed. Moreover, the base portion 12a is thicker than the plate-like portion 11 while maintaining the original thickness. Therefore, the head 12 can sufficiently prevent the fixing member 2 from breaking from the hog ring portion.

When the fixing member 2 is formed by an injection molding method or the like, the base portion 1 of the plate-shaped portion 11 and the head portion 12 are formed.
Since the thickness of 2a and the pair of upright portions 12b and 12c is substantially constant, when molding by the injection molding method,
The width of each part of the mold cavity is also constant. Therefore, the resin is uniformly filled in the cavity of the mold. Therefore, any part of the fixing member 2 can be formed into a desired shape. Also in the case of the extrusion molding method, since the width of each portion of the slit of the die through which the resin passes is substantially constant, the entire fixing member 2 can be formed into a desired shape. The resin that forms the fixing member 2 is a seat cover S or a seat pad P (FIG. 4).
It is desirable to use the same resin as that described in (1), and particularly to use a recyclable resin.

The fixing member 3 shown in FIG. 2 is formed so that the head 12 becomes thinner as it separates from the plate-like portion 11 side, and approaches the plate-like portion 11 side to the side surface of the head. The thickness of the head portion 12 is larger than the plate portion 11 at least at the base portion 12a. The width of the opening of the groove 13 is the same as the width of the side surface of the head 12 where the groove 13 is formed. As a result, the head 12 is
And two crests 12d, 12d having a triangular cross section.

The fixing member 4 shown in FIG.
An elongated hole 14 extending along the longitudinal direction of the plate-shaped portion 11 is formed in the vicinity of the head 12 of the first unit 12, and the elongated hole 14 is arranged in accordance with a portion to be hogled. In the fixing member 4, the hog ring can be easily performed by inserting the wire for the hog ring into the long hole 14. The reason why the elongated hole 14 was formed instead of a mere hole is that
This is to cope with variations in the hog ring position.

Note that the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention. For example, each of the above fixing members 2, 3, 4
Can be used not only for vehicle seat covers, but also for furniture seat covers and other covers.

[0017]

As described above, according to the cover fixing member of the present invention, a groove extending along the longitudinal direction of the head is formed on the side of the head opposite to the plate-like portion. Therefore, the fixing member can be prevented from being broken from the hog ring portion by the head portion, and the thin plate portion can be formed into a desired shape.
