Description of the Related Art In general, seats used for automobiles, office chairs and the like are constructed by attaching a seat cover to a surface of a cushion material made of urethane foam or the like. In attaching the seat cover to the cushion material surface, recently, a surface fastener tape having a large number of engaging element groups on the front surface and a large number of buried element groups on the back surface has been used, and this tape has been molded in molding technology. Utilizing the method, the embedded element group is embedded in the cushion material on the surface of the cushion material, and the engaging element group is embedded and integrally molded so as to be exposed on the surface of the cushion material. . The seat cover is provided with a group of engaged elements that can be engaged with the group of engaging elements of the hook-and-loop fastener tape. By engaging these elements, the seat cover is aligned with the cushion material. And is tightly covered.

いる。When performing the mold-in molding using the surface fastener tape, the surface fastener tape is fixedly set in a molding die, and a foaming stock solution of a molding material flows into the engagement element group side of the tape during molding. Need to be prevented. Therefore, in this case, the hook-and-loop fastener blocks the inflow of the undiluted solution by using means as shown in FIG.

Using a surface fastener tape E having a large number of engaging elements C and buried elements D, a steel paper F to be attracted to a magnet buried in a mold during molding is provided on the outer surface side of the engaging elements C. At the same time, a fastener cover film G that covers the steel paper F and the engaging element C and that prevents the molding material from flowing into the engaging element C during molding is attached. The outer peripheral edge of the film G is integrally joined to the peripheral edge of the tape E by a processing means such as hot melt or ultrasonic processing.

In addition, each of the F and G generated in this operation becomes unnecessary waste, and a pollution problem occurs. Further, if film scraps remain on the engaging element surface when the film G is removed, the engaging force is reduced or the appearance is deteriorated. ,
There is a major problem that workability is poor, and furthermore, there is a risk that finger injury may be caused when the steel paper F is removed.

Since the shape of the fastener is exactly a flat tape shape, it can bend smoothly when it is bent vertically with respect to the tape surface, but in the left-right width direction with respect to the tape surface, In particular, it is impossible to bend in the left-right width direction within the same plane. Therefore, if such a surface fastener tape can be embedded and molded into the surface of the cushion material by mold-in molding, the surface fastener tape can be arranged on the same surface of the cushion material, This is only in the case where it is arranged in a state of being bent in the vertical direction.

It is impossible to arrange the surface fasteners freely on any surface, so that the cushion material and the seat cover cannot be connected and smoothly connected three-dimensionally and smoothly. In order to cope with this three-dimensional curved surface, the surface fastener is finely divided, and the direction of the surface fastener is changed and arranged. This is because the steel paper F and the fastener cover film G are attached. Removal work becomes more complicated, and three-dimensional continuous connection between the cushion material and the seat cover cannot be expected.

(The locking member 5 is disposed on the outer surface side.) A protrusion 10 for forming the groove 4 is provided, and a concave groove 11 for mounting the locking member 5 is provided on the upper side of the protrusion 10. .

As shown in FIG. 4, when the locking member 5 is fitted at the time of the mold-in molding, the outermost left and right outermost positions 12 a and 12 b of the locking member 5 are opposed to the opposite wall surfaces 13 in the width direction of the concave groove 11.
a and 13b are in close contact with each other, and have a dimensional relationship that does not create a gap. This close contact state means at least the extent to which the tip of the group of engaging elements 7 on the surface of the locking member 5 comes into contact with the opposing wall surfaces 13a, 13b. If both are in contact, the viscosity of the foaming stock solution is high to some extent, so that the foaming stock solution can be prevented from flowing into the inner space S1 in the recessed groove 11 at the contact position, that is, sealing can be performed, and thereby, the sheet is formed later. Engaged element 1 on cover 3 side
Engaging element 7d on locking member 5 side to be engaged with fourth group
The group can be prevented from being buried with the foamed material. However, there was no contact between them and 1m
If the dimensional relationship is such that a gap of at least m is formed, the sealing effect of the foaming liquid between the two is impaired. Also, the sealing at the both end surfaces in the length direction of the locking member 5 and the recessed groove 11 for mounting the locking member 5 is cut so that the end surfaces are at least in contact with each other in the same manner as described above. And adjust it.

のを阻止する。An example of manufacturing the cushion material 2 using the above-described locking member 5 for mold-in molding will be described. First, as the mold-in molding locking member 5, a member having a group of engaging elements 7 formed of hooks and / or loops formed on a circumferential surface having a circular cross section as shown in FIG. 3 is used. This is set in the concave groove 11 of the molding die 8 as shown in FIG. In this set state, the left and right ends in the width direction and the front and rear ends in the width direction of the locking member 5 and the opposed wall surfaces 13a and 13b in the width direction of the concave groove 11 and the front and rear ends in the longitudinal direction are in close contact with each other. The space between the inner space S1 of the concave groove 11 and the mold interior space S2 in the mold 8 filled with the mold resin is sealed, and when the foaming stock solution is injected into the molding mold 8, the foaming stock solution is removed. This prevents the inflow into the engagement element 7d group side in the inner space S1 of the concave groove 11.

る。In this state, the inner space S of the molding die 8 is
The resin is injected into the foam 2 and foamed. After the resin is cured, the cushion material 2 is taken out of the molding die 8 so that the engagement element 7u existing in the space S2 is inserted into the surface side groove 4 of the cushion material 2. Are integrally embedded, and the engaging element 7d existing in the space S1 is reliably exposed to the outer surface of the cushion material 2. In the present invention, since the locking element 5 of the locking member 5 is provided on the peripheral surface of the flexible body having a circular cross section, the locking element 5 is three-dimensional. Even if it is set in the concave groove 11 inside the mold and subjected to foam molding, any one of the engaging elements 7 on the peripheral surface is in contact with the element 7d on the space S1 side (that is, on the outer surface of the cushion material 2). This is a feature that can be an exposed engaging element and an element 7u on the space S2 side (that is, an embedded element embedded in the cushion material 2).

要請を初めて実現したものである。As described above, according to the mold-in molding technique of the present invention, a member provided with an engaging element on its peripheral surface is bent in any direction as the mold-in molding locking member. By using, the workability and safety are much better than when using conventional hook fasteners, and it is an excellent mold-in manufacturing method in that it does not generate unnecessary waste. In particular, the molded material has a three-dimensional three-dimensional curved surface shape, and the covering sheet cover is continuously and smoothly bonded along the three-dimensional curved surface shape. This is the first time that a request has been made.
