BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface fastener body for molding which is embedded in a cushion body such as an automobile or office chair when the cushion body is molded.

[0002]

2. Description of the Related Art Generally, seats for automobiles, offices, etc. are usually constructed by attaching a seat cover to the surface of a cushion material made of urethane foam or the like. When installing this seat cover, a seat cover having a shape substantially the same as that of the cushion material is conventionally sewn, and the seat cover is covered along the surface of the cushion material,
The two were fixed by hog rings or adhesive means.

However, as described above, when the seat cover is fixed to the cushion material by the hog ring or the adhesive means, a large number of fixing tools and the like are required, and fixing with these fixing tools also requires a lot of labor. . Moreover, when the seat cover is fixed to the cushion material side using a large number of fixing tools, the cushion material is deformed and the appearance of the seat cushion or seat back is changed, and it is difficult to obtain stable quality. There are also problems such as.

On the other hand, recently, a surface fastener having a large number of engaging elements on the front surface and a large number of embedded elements on the back surface is used, and this surface fastener is embedded in the surface of the molded body to be molded, so-called mold-in. Molding technology was developed. The embedded element on the back surface of the embedded surface fastener is embedded and engaged in the molded body, and the engaging element on the front surface is exposed on the outer surface of the molded body.

Therefore, by utilizing the above-mentioned mold-in molding technique, a surface fastener is attached to the surface of the cushion material in an exposed manner, and the seat cover is engaged with an engaging element of the surface fastener. It has been considered that the seat cover is covered along the cushion material by mounting the elements and engaging the engaging elements with the engaged elements. As a surface fastener body preferably used in that case, there is a known surface fastener body A as shown in FIG.

In FIG. 6, a surface fastener body A uses a surface fastener E having a large number of engaging elements C and embedded elements D on both front and back surfaces of a base material B, and is provided on the outer surface side of the engaging element C. The metal plate F attracting the magnet body embedded in the mold during molding is provided, and the metal plate F and the engaging element C are entirely covered so that the molding material flows into the engaging element C side during molding. A film G is attached to prevent this. The outer peripheral edge portion of the film G is joined and integrated with the peripheral edge portion of the surface fastener E by heat sealing processing means or the like.

Then, the metal plate F is attracted to the magnet body in the mold, the surface fastener D is positioned with respect to the mold, a molding material is injected into the mold, and the embedded element C is embedded. Then, the metal plate E and the film F are removed, and the engaging element C is exposed on the surface of the mold or the molded body.

[0008]

However, in the above surface fastener body A, since it is necessary to attach the film G for preventing the inflow of the molding material to the engaging element C side by means of heat sealing processing means, etc. Regardless of when the fastener body A is linear, it is extremely difficult to form the surface fastener body A in a continuous curved shape or the like due to the difficulty of heat sealing. Therefore, it is not possible to adequately support applications such as seats where designs are complicated and diversified. In addition, although it is possible to arrange a plurality of linear surface fastener members A corresponding to a complicated design, in that case, a gap is generated between the adjacent surface fastener members A. Therefore, a portion of the seat cover corresponding to the gap is dented and the appearance is deteriorated.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a surface-molding fastener for molding, which has a simple structure and can cope with a complicated design.

A fastener cover that includes a body and covers the engaging elements, and a sealing material that is provided on a back surface of the fastener cover and fills a gap between the engaging elements are provided.

[0011]

By cutting or die-cutting the surface fastener body having the above-described structure, it is possible to easily obtain even a complicated shape, and it is possible to cope with a variety of uses in which the design is complicated. Further, since the surface fastener body can be continuously cut or die-cut even if the design is complicated, even if the portion of the molded body that needs to be engaged with the seat cover has a complicated shape, By embedding the hook-and-loop fastener body processed into a different shape into the molded body and covering the seat cover from above, this sheet cover can be reliably covered along the outer shape of the molded body, and the appearance is good. The design can be accurate.

Further, since a sealing material is provided on the back surface side of the fastener cover and the sealing material fills the gap between the engaging elements of the surface fastener, a molding material is applied between the engaging elements during molding. Can be prevented from flowing in,
By removing the sealing material after molding, the engaging element can be reliably exposed on the outer surface of the molded body. The sealing material also serves to attach the fastener cover to the engaging element, that is, the surface fastener.

Further, since the fastener cover includes a magnetic body or a magnet body, when the surface fastener body is set in the molding die, it can be easily and surely positioned and set.
