本発明は、例えば乗物用シートや寝具、家具等
に用いられるクツシヨン体の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a cushion body used for, for example, vehicle seats, bedding, furniture, and the like.
シート用クツシヨン体には様々な種類がある

There are various types of cushion bodies for seats, but among them, the integrally molded pad, which is made of urethane foam or the like and covered with a skin such as woven fabric, is breathable, has excellent cushioning properties, and has good durability. .

表皮をパツドに固定するといつた方法もある。 As a conventional method for manufacturing this type of cushion body, a method is known in which an adhesive is applied to the surface of the urethane foam by spraying, and the outer skin is fixed to the pad with the adhesive. Alternatively, there is a method in which a hot-melt adhesive sheet is provided between the pad and the skin, and this is heated in an oven or hot press to melt the adhesive sheet and fix the skin to the pad.

Among the conventional methods described above, in the method of applying the adhesive by spraying, the amount of adhesive applied tends to vary, and the epidermis may peel off from the pad in areas where the adhesive is not sufficiently applied. Moreover, spraying solvent-based adhesives creates a poor worksite environment, requiring special consideration for ventilation, etc., which requires large-scale equipment and a large workspace. Moreover, it takes time to volatilize the solvent, resulting in poor productivity.

要し、生産性に劣る。また、接着シートの溶融に

因となる。 On the other hand, a method using a hot-melt adhesive sheet can solve the above problem, but requires a long time for heating because it is melted by heating in an oven or by pressing, and is inferior in productivity. Furthermore, if the skin becomes clogged due to melting of the adhesive sheet, it causes poor air permeability.

The method for manufacturing a seat cushion body of the present invention includes:
For example, with a hot melt adhesive sheet sandwiched between the surface of a breathable pad such as urethane foam and the breathable skin,
The pad is pressed from the outside into a predetermined shape using a mold, and high-temperature steam or hot air is sent from the skin through the adhesive sheet to the pad side through the mold, thereby melting the adhesive sheet and bonding the skin and pad together. It is characterized by being glued together. Note that wading may be interposed between the skin and the pad.

In the above method, the adhesive sheet is heated and heated by sending high-temperature steam or hot air to melt the hot-melt adhesive sheet from the breathable skin to the pad side through the adhesive sheet.
Since it is melted, no solvent is required and it can be bonded in a short time, resulting in good productivity.Even when the adhesive sheet is melted, the skin does not get clogged and air permeability is ensured. Note that when a substance that reacts with water, such as a urethane-based binder, is used in the adhesive sheet, adhesion is better achieved by supplying water vapor.

成形されている。[Example 1] As shown in FIG. 1, the seat cushion body 1 of this example comprises a pad 2, a hot-melt adhesive sheet 3, a skin 4, and the like. The skin 4 is made of a breathable woven fabric and consists of a seating part 4a and a side part 4b. The pad 2 is an integrally molded product of a synthetic resin foam having air permeability and elasticity, such as open-cell urethane foam, and is molded into a predetermined shape.

接着シート３および表皮４は、以下に述べる工程
を経て互いに一体化させられる。 The hot-melt adhesive sheet 3 melts when heated to a predetermined temperature and exhibits properties as an adhesive, and is made of a web (woven fabric) or non-woven fabric so as to have air permeability. This adhesive sheet 3 is cut to a size that roughly corresponds to the seating portion 4a. The pad 2, adhesive sheet 3, and skin 4 are then integrated with each other through the steps described below.
まず、縫い合わせによつて着座部４ａと側部４

（第２図および第３図参照）。 First, the seating part 4a and the side part 4 are sewn together.
The outer skin 4 consisting of b is sewn. In terms of design, the colors of the seating portion 4a and the side portions 4b may be made different from each other. Next, the adhesive sheet 3 is placed on the pad 2 that has been formed into a predetermined shape, and the skin 4 is placed on top of it, and the end portion 4c of the skin 4 is fixed (see Figures 2 and 3). ).
次いで、第４図に示されるように、パツド２の

通気小孔が開設されている。 Next, as shown in FIG. 4, press surfaces 6a and 7a corresponding to the shapes of the upper and lower surfaces of the pad 2 are
By pressing the mold between the upper mold 6 and the lower mold 7 and pumping high-temperature steam into the mold 6 through the air inlet 9, the high-temperature steam is transferred from the skin 4 through the adhesive sheet 3 to the pad 2 side. send to. A large number of small ventilation holes are provided on the press surface 6a of the mold 6 so that steam can be blown out.

Remove from the molds 6 and 7 and remove the terminal part 4ac of the epidermis.
By stopping , the cushion body 1 shown in FIG. 5 is produced.

れている。 According to the above method, there is no variation in the amount of adhesive applied as seen in conventional adhesive spray application, and uniform adhesive strength can be obtained on the adhesive surface. Also,
Since the process of spraying an adhesive such as a solvent-based adhesive and the process of volatilizing a solvent are not necessary, the process is simplified and the working environment is not deteriorated. Moreover, since the hot-melt adhesive sheet 3 is heated by contact with steam, it has good thermal efficiency and can be bonded in a short time. Therefore, heating time is short and productivity is excellent.

を防止できる。 Note that water droplets adhering to the skin 4 may be removed by reducing the pressure inside the mold 6 after the steam bonding step. Alternatively, the adhesive sheet 3 may be applied to the back side of the skin 4 in advance by an appropriate means. With a laminate structure like this,
Even when the adhesive sheet 3 is quite thin, it is easy to handle when setting it on the pad 2, it can be reliably set in a predetermined position, and defective adhesion due to misalignment of the adhesive sheet 3 can be prevented.

ようにしてもよい。 In addition, the adhesive sheet 3 is preferably web-shaped in order to ensure air permeability, but it is also possible to use a film-shaped adhesive sheet. In this case as well, since steam or hot air is sent from the skin 4 through the adhesive sheet to the pad 2, clogging of the skin 4 can be prevented and breathability can be maintained. In addition, wading made of the same material as pad 2 is pasted on the back side of the skin 4 in advance, and this wading and pad 2
and may be adhered to each other by the adhesive sheet 3.

る。[Example 2] As in Example 1, a breathable skin 4 consisting of a seating part 4a and a side part 4b is made by sewing. This is then molded into mold 6 as shown in Figure 6.
Cover the press surface 6a and fix it. The shape of the press surface 6a corresponds to the seating surface of the pad 2.

A pad 2 made of urethane foam or the like is further laminated thereon (see FIG. 7). This pad 2 is previously formed into a predetermined shape.

行なつてもよい。 Next, after pressing the pad 2 from above with a mold 7, high-temperature steam is sent into the mold 6 through the air inlet 9 and ejected from the skin 4 toward the pad 2, thereby melting the adhesive sheet 3 and forming the pad 2.
and adhesion of the epidermis 4. Thereafter, the molds 6 and 7 are removed and the cushion body 1 is taken out. Further, the side portion 4b of the skin is turned over and placed over the pad 2, and the terminal portion 4c is fixed. As described in Example 1, the pressure inside the mold 6 may be reduced after the steam bonding process to remove water droplets attached to the skin 4, or wading may be pasted on the back side of the skin 4. It's okay to be hot. Further, if necessary, after the skin 4 is set in the mold 6, the skin 4 may be preformed by a press.
