DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retainer for retaining a skin end of a vehicle seat which is excellent in mounting workability and does not generate abnormal noise during use.

[0002]

2. Description of the Related Art Conventionally, as a retainer used to organize the terminals of a seat cover of an automobile or the like, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 3-109597, the terminal of the epidermis is sewn and locked on a frame. 2. Description of the Related Art A retainer for retaining a skin end having a substantially J-shaped cross section is known. In such a retainer, the terminal of the epidermis is fixed by hooking the J-shaped portion to the end face of the frame, and the terminal of the seat cover is easily assembled.

However, as shown in FIG. 4, when a flange 31 is formed at the lower end of the frame 30 and a J-shaped skin terminal retaining retainer 32 is to be engaged with the flange 31, a seat track Since the gap between the upper rail 33 and the flange portion 31 is narrow, and the opening of the retainer 32 is also narrow, there is a problem that it is difficult to insert into the flange portion 31 and it is difficult to perform a locking operation. In addition, it has a hooking structure in which a J-shaped member is simply hooked, and generates an unusual noise due to rattling during running, and a retainer 2 due to rattling.
There was also a problem that 2 came off.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and is excellent in mounting workability.
Further, the present invention has been completed for the purpose of providing a retainer for retaining a skin end of a vehicle seat, which does not generate abnormal noise or a detachment phenomenon during use.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a retainer for retaining a skin end of a vehicle seat according to the present invention has an intermediate bottom surface at a bottom portion of a retainer main body having a substantially L-shaped cross section. A sewing part for sewing the terminal of the epidermis is provided vertically, and a hook part for hooking a flange part is formed at a free end of this bottom part, and further, at a top end of a rising part mainly composed of a retainer. Is characterized in that a pressing piece for applying a pressing force to the frame at the time of hanging is extended.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. The drawing shows a case in which a seat cover of a front seat for an automobile as shown in FIG. 3 is hooked. In the drawing, 1 is a cross-sectional view made of a hard plastic such as a hard polypropylene resin or a polyethylene resin. An L-shaped retainer main body, a sewn portion 1a for sewing an outer skin terminal is vertically provided on an intermediate bottom surface of a bottom portion of the retainer main body 1, and a flange portion 11 is provided at a free end of the bottom side portion. Hook 1b for hooking
It has been. Further, a pressing piece 1c for applying a pressing force to the frame 10 when the frame 10 is locked is provided on the upper end of the rising portion following the other end of the bottom side portion of the retainer main body 1.
Are extended so that the opening 2 is formed between the hook 2 and the hook 1b. Although the pressing piece 1c is a simple inclined piece in the one shown in FIG. 1, the retainer main body 1 and the pressing piece 1c are outwardly bent pieces as shown in FIG.
May be formed in a U-shape in cross section with the base part. 1d is a bent pressing end formed on the free end of the pressing piece 1c, 1e is an engaging groove formed on the inner base of the hook 1b, and 11 is a frame 10 for hooking the retainer.
, A reference numeral 20 denotes a skin whose terminal is sewn to the sewn portion 1a of the retainer, 21 denotes a cushion pad, and 22 denotes a suture for sewing the skin and the retainer.

The retainer body 1 is basically made of a hard plastic such as a hard polypropylene resin or a polyethylene resin, but only the sewn portion 1a is made of, for example, a thermoplastic resin elastomer or a soft polypropylene resin. If it is formed of a soft plastic such as polyethylene resin, the workability of sewing with the skin 20 is improved, and the shape 20 is well conformed and the skin 20 is evenly and smoothly pulled when hooked, so that excellent appearance quality can be obtained. This is preferable because it can be guaranteed.

[0008] In the above-mentioned construction, the terminal of the skin 20 is sewn in advance to a sewn portion 1a vertically provided from an intermediate bottom surface at the bottom of the retainer main body 1, and this is attached to the frame 1
0, but the opening 2 is wider than that of the conventional one having a substantially J-shaped cross section, so that the mounting to the flange 11 can be performed very easily. The mounting operation can be performed in a short time only by pushing the opening 2 having a wide direction toward the flange 11. On the other hand, even after the mounting, the retainer itself is firmly fixed to the flange portion 11 with the hook portion 1b, so there is no risk of detachment, and the pressing piece 1c is pressed so that no gap is generated between the retainer and the frame 10. Frame 1
Since the close contact state is maintained by constantly applying a pressing force to 0, rattling is prevented and generation of abnormal noise can be reliably prevented. Further, when the sewn portion 1a is formed of a soft plastic such as a thermoplastic elastomer, the sewn portion 1a is freely bent to conform to the outer shape of the flange portion 11 in the hooked state, and has an optimum shape. Since the skin 20 is pulled in the state, the skin 20 is stretched uniformly and without difficulty, so that excellent appearance quality without wrinkles or looseness can be guaranteed.

[0009]

As is apparent from the above description, the present invention is excellent in mounting workability, and is of high quality without generation of abnormal noise or occurrence of detachment during use. Therefore, the present invention greatly contributes to the development of the industry as a retainer for fastening a skin end of a vehicle seat that has solved the conventional problems.
