材を接着したものが好ましいとされている。(Prior Art) Conventionally, as a cushion product such as an automobile or furniture seat or an automobile headrest, a center armrest or the like, a skin 12 is formed on a surface of a cushion body 10 made of a flexible polyurethane foam or the like as shown in a sectional view of FIG. Is often used. The skin 12 is preferably made of a material such as fabric, genuine leather, or a plastic sheet in which an elastic material such as a slab foam (a soft polyurethane foam) is adhered to the back surface in order to improve aesthetic appearance and surface feel. ing.
一方、そのクッション製品の簡易な製造方法として、
表皮一体成形法による製造方法がある。その製造方法

その表皮12内にポリウレタンフォーム原料等の液状発泡
原料16を注入し、表皮と一体に発泡成形する方法であ
る。On the other hand, as a simple manufacturing method of the cushion product,
There is a manufacturing method using a skin integral molding method. The manufacturing method is as follows. As shown in FIG. 8, the skin 12 is placed in the foaming mold 14,
In this method, a liquid foaming raw material 16 such as a polyurethane foam raw material is injected into the skin 12 and foamed integrally with the skin.

硬化して、クッション製品の表面が硬くなる問題があ
る。However, if the skin is integrally molded as described above using a skin in which an elastic material such as slab foam is adhered to the back surface of the fabric or the like, the liquid foaming material impregnates and cures the elastic material at the time of its manufacture, and the surface of the cushion product is hardened. There is a problem of becoming hard.

ッション製品が表面近くで蒸れ易い欠点があった。(Problems to be Solved by the Invention) However, in the cushion product, the three members of the surface material 18, the elastic material 22, and the plastic film 20, which constitute the skin, are integrally bonded to each other, so that the skin is soft. There was a drawback that it lacked in properties and gave a sense of tension. Further, the three members constituting the skin are adhered on the entire surface, and the texture of the surface material and the pores of the elastic material on the adhesion surface are blocked by the adhesive, so that the permeability of the skin is impaired, There was a disadvantage that the cushion product was easily stuffy near the surface.
さらに、表皮の表面材が本革のように収縮率の高い材

たのである。(Means for Solving the Problems) In order to achieve the above object, a first aspect of the present invention provides a method for sewing a plurality of skin constituent pieces having a three-layer structure in which a surface material and a plastic film are bonded and integrated via an elastic material. In a cushion product in which the obtained skin is adhered to the surface of a cushion body having a predetermined shape, the surface material, the elastic material and the plastic film are bonded only at the end of the skin constituent piece, and the other part of the skin constituent piece With respect to (1), one or both of the surface material and the plastic film and the elastic material are not bonded.

In a method of manufacturing a cushion product by injecting a liquid foaming raw material into the skin and foaming it integrally with the skin, the bonding of the surface material, the elastic material and the plastic film is performed only at the end of the skin constituent piece. For the other part of the skin constituent piece, one or both of the surface material and the plastic film and the elastic material are not bonded to each other and the skin is arranged in a foaming mold, and the liquid foaming material is injected and foamed. It was done.

面にしわを生じることがない。(Function) In the cushion product, the back surface of the skin adheres to the surface of the cushion body, and the skin and the cushion body are integrated. However, the surface material, the elastic material, and the plastic film constituting the skin component piece are bonded only at the end of the skin component piece, and one or both of the surface material and the plastic film are combined with the elastic material at the other part of the skin component piece. The surface material of the skin can be deformed at the non-adhered portion without being bound by the plastic film and the cushion body on the back surface of the skin. Therefore, the free deformation of the skin surface material at the non-adhered portion eliminates the feeling of tension on the skin surface. Further, in the non-adhesive portion, since the skin surface material can be stretched by being bound by the cushion body on the back surface of the skin,
Even if the surface material is made of a material having high elasticity such as genuine leather, the expansion and contraction is not hindered, and the surface of the skin does not wrinkle.

の通気性が向上することになる。Further, when the end portion of the surface material and the end portion of the elastic material are not bonded, the texture of the surface material between the end portions,
Since the pores and the continuous ventilation holes of the elastic material are not closed by an adhesive or the like, the air in the epidermis is textured by the surface material,
It can be circulated to the outside through the holes and the like, and the permeability of the epidermis is enhanced. Further, even when the surface material and the slab foam of the elastic material are entirely bonded by fire welding, and the other surface of the elastic material and the plastic film are not bonded except at the end of the skin constituent piece, the fire welding is performed on the slab. Because the surface skeleton of the foam is melted by a fire and the surface material and the slab foam (elastic material) surface are welded,
The adhesion between the elastic material and the surface material is a kind of point adhesion, and the flow of air between the elastic material and the surface material is not hindered. As a result, the skin can be circulated to the outside of the skin through the elastic material and the surface material, and the air in the space in the non-adhesive portion of the elastic material and the plastic film constituting the skin, and the air in the elastic material can be circulated. This also improves the air permeability of the cushion product surface.
加えて、前記表面材と弾性材とプラスチックフィルム
は、表皮構成片の端部で互いに接着されているため、剥
離することもない。In addition, since the surface material, the elastic material, and the plastic film are bonded to each other at the ends of the skin constituent pieces, they do not peel off.

る場合であっても表皮表面にしわを生じることがない。The cushion product 24 is formed in a state of being heated by the heat of the foaming mold and the foaming of the liquid foaming raw material. Attempts to shrink at a shrinkage of. At this time, since the non-adhesive portion existing between the surface material 32 of the skin and the elastic material 30 allows the skin surface material 32 to contract without being bound by the cushion body 26 on the back surface of the skin, the surface material 32 Does not cause wrinkles on the surface of the skin even when it is made of a material having a high shrinkage rate such as genuine leather.
なお、他の表皮構成片36,38からなる表皮を用いるク
ッション製品であっても、表皮の非接着部において表面
材がクッション体に束縛されることなく収縮できるた
め、表皮にしわを生じることがない。In addition, even in a cushion product using the skin composed of the other skin constituent pieces 36 and 38, the surface material can be shrunk without being bound by the cushion body in the non-adhesive portion of the skin, so that wrinkles may occur on the skin. Absent.
また、このようにして得られたクッション製品は、表
皮構成片の端部間の層間に形成された非接着部によっ
