Description

[Detailed Description of the Invention] The present invention relates to a seat cover fastening button device for fixing the cover covering a pad in a vehicle seat or the like.

Fig. 1 shows a general conventional example of a button device for fixing the seat skin, in which the string 3 of the button 2 is inserted into the pad 4 from the front side of the skin trim 1, and comes out from the cross 7 on the back side of the pad 4. At this position, the knot 8 of the string 3 is locked and held in the slit 6 of the locking piece 5. As a holding means for the string 3, for example, the string 3 may be hooked on a locking protrusion formed on the frame of the seat (see Japanese Utility Model Publication No. 57-2855), or a string-like body made of plastic may be used instead of the string 3. , by locking a retaining protrusion protruding from a string-like body to a locking piece (see Utility Model Publication No. 57-38051), etc.
There are various structures, but all conventional ones have a structure in which a button string or something similar is fastened to the back of the pad. Therefore, in the case of a structure in which a bag-shaped skin trim is placed over the seat, such as the seat bag of an automobile seat, there is a problem in that work efficiency is poor because it is difficult to access the back side, and the work cannot be carried out efficiently. Therefore, the design of the seat was sometimes restricted.

The present invention has been devised to address these problems and to provide a fastening button device that allows the skin trim to be attached only by working from the front side. A fastening button device is constituted by a button body, and a holder corresponding to the button body, which is exposed on the surface of the pad and is pulled into the pad and installed,
The button body and the holder are respectively provided with locking portions that lock each other. That is, according to the present invention, the holder is attached to a predetermined location in the preliminary work before the skin trim is attached, and then the button body is locked to the holder while holding the skin trim with the button body. The holder installation work is easy, and workability is greatly improved.

Next, an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

As shown in the exploded perspective view of FIG. 2, the button body 11 has a locking portion 12 protruding from the back surface, and the locking portion 12 has a slit 13 to provide elasticity.
are provided in the longitudinal direction, and a locking pawl 14 is formed at the tip. On the other hand, the holder 15 has a hole in which the locking part 12 is inserted and the locking claw 14 is locked, and this is used as the locking part 16. A string 17 having a knot 18 in the middle is connected to the hole. A locking piece 19 having a slit-like cut 20 for locking the locking piece 18 is attached.

In use, as shown in FIG. 3, the locking portion 12 of the button body 11 is inserted into a predetermined position of the skin trim 1 from the front side, and temporary assembly is performed. Correspondingly, the string 17 of the holder 15 is inserted into a predetermined position of the pad 4 from the front side, and the locking piece 19 is inserted at the position where the knot 18 comes out from the set cloth 7 on the back side of the pad 4.
By locking in the notch 20 of the pad 4
The holder 15 is attached with the holder 15 exposed on the surface of the pad 4 and pulled into the pad 4. Next, the skin trim 1 is placed over the pad 4, and the locking pawl 14 of the locking portion 12 of the button body 11 is locked with the locking portion 16 of the holder 15. This completes the assembly shown in FIG. Become. In this way, when attaching the holder 15 to the pad 4, the skin trim 1 has not yet been covered, so even if the skin trim 1 is bag-shaped, the work of installing the holder 15 is easy, and the work efficiency is improved. The performance of the skin trim 1 is improved, and the covering operation of the skin trim 1 can be carried out efficiently.

Note that the structure of the locking parts 12 and 16 that locks the button body 11 to the holder 15 and the structure that attaches the holder 15 to the pad 4 in the embodiment are examples, and other structures may be adopted as appropriate. can do.

As mentioned above, the present invention consists of a button body that is placed on the surface of the skin trim and a holder that is attached to the pad in advance, making it possible to cover the skin trim even when the skin trim is in the form of a bag. This has the advantage that it can be easily done and the design is not restricted.
