Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a skin-integrated foam-molded article used for automobile headrests and the like.

[Prior Art] Conventionally, as a headrest of an automobile, a foam-integrated foam-molded product obtained by foaming a foam material in a skin cover that is sewn in advance in a bag shape is often used. Since a headrest or the like needs a reinforcing core body inside, an opening for inserting the core body must be provided in the skin cover, and the opening portion must be closed after the core body is inserted. .

Conventionally, there are the following means for closing the openings.

As shown in FIG. 5, foldable closing pieces 3, 3, ... Having a plurality of engaging holes 4 are formed at the edge of the opening 2 of the skin 1, and a plurality of engaging protrusions 6 are formed. The sealing members 5 and 5 having separate bodies are provided and placed, and after the sealing pieces 3, 3, ... Are bent inward, the engaging protrusions 6 of the sealing members 5 and 5 are engaged with the respective engaging holes 4. Combine and block.

As disclosed in Japanese Unexamined Patent Publication No. 63-92420, a set of sealing members each having a large number of engaging protrusions or engaging holes are arranged at the edge of the opening, and they are engaged with each other. This closes the opening.

Since the skin material has flexibility, in any of the above cases, the number of engaging points is increased to prevent the positional displacement of the closing.

[Problems to be Solved by the Invention] However, any of the above means requires a sealing member having a relatively complicated configuration, which results in high material cost and complicated closing work because there are many engaging points. there were.

Therefore, an object of the present invention is to provide a skin-integrated foam-molded product which reduces the material cost, facilitates the closing work, and has no positional deviation of the closing and has stable quality.

[Means for Solving the Problems] In order to achieve the above object, the present invention comprises inserting a core body from an opening formed in a bag-shaped skin cover and foaming a foam material in the skin cover. In the skin-integrated foam-molded article, a folded portion having a void is formed at the edge of the opening, and a clip-shaped closing member is inserted into the void to close the opening. In the foam-integrated body with integrated skin, wherein the core body is inserted from the opening formed in the bag-shaped skin cover and the foam material is foamed in the skin cover, the end of the opening is provided. Forming a folded-back portion having a void at the edge, inserting a clip-shaped closing member into the void to close the opening, and at the core body at a position corresponding to the opening of the epidermis cover. , It is specially equipped with a recess for alignment. And a second claim as a characteristic.

[Operation] Since the opening can be closed simply by inserting the clip-shaped closing member having a simple structure into the folded portion of the edge of the opening of the skin cover, the closing work becomes easy and the workability is improved. It also improves the material cost. Further, since the position of the skin cover can be easily adjusted, the position shift can be prevented.

[Embodiment] FIG. 1 to FIG. 4 show a skin-integrated foam-molded article applied to an automobile headrest as an embodiment of the present invention.

FIG. 1 is a leg member 11 of the headrest 10 shown in FIG.
In a perspective view seen from below, the skin cover 12 has a flexible foam 14 attached to the back surface of a skin material 13 made of woven fabric, knitted fabric, etc. as shown in FIG. A plastic film (for example, a polyurethane film) 15 for preventing the invasion of the foam material is attached to the surface of the sheet by heat welding or the like. This skin cover 12
Is cut and sewn into the desired shape,
The opening 16 into which the core body 22 shown in FIG. 3 can be inserted is provided.

As shown in FIG. 2, the opening 16 has both end edges folded back inward and sewn to form a folded portion 17 having a space 17a. Further, the notch 1 facing a part of each folded-back portion 17
8 is provided, and the insertion port 20 of the blocking member 19 is opened.

The blocking member 19 is a clip-shaped member in which a pair of opposed pieces 21 and 21 whose tips are pressed against each other are integrally molded, and two are used in this embodiment. Further, as shown in FIG. 3, the core body 22 is formed with a recess 24 corresponding to the opening 16 of the outer cover 12 or the seam allowance on the surface provided with the stay 23 so that the core body 22 can be aligned when closed. Has become.

Therefore, in order to manufacture the headrest 10, first, the core body 22 is inserted from the opening 16 of the bag-shaped skin cover 12, and then the facing member of the blocking member 19 is inserted from the insertion opening 20 of the notch 18 of the opening 16. 21 and 21 are inserted into the space 17a and the opening 16 is closed.

Then, the position of the closed portion is set to the concave portion 2 of the core body 22.
After the positional deviation is corrected so as to match with No. 4, it is placed in a molding die, and a foaming material is injected into the skin cover 12 to cause it to foam and integrally molded.

[Effects of the Invention] As described above, in the present invention, the opening can be closed by simply inserting the clip-shaped closing member having a simple structure into the folded portion of the edge of the opening of the skin cover. , The closing work is facilitated, the workability is improved, and the material cost is reduced. Further, since the position of the skin cover can be easily adjusted, it is possible to obtain a skin-integrated foam-molded product of stable quality without positional displacement.
