本発明は自動車の座席用等に使用されるクッションの製
造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing cushions used for automobile seats and the like.
自動車の座席のクッション等は、モールドにより自由な
形状のものを大量に作ることができるため、一般的に種
々の補強材をインサートしたウレタンの一体発泡成形品
が使用されている。Since car seat cushions and the like can be made in large quantities into any shape by molding, integrally foamed urethane molded products with various reinforcing materials inserted are generally used.
しかしながらこのようにして得られたクッション体は型
で発泡成形するのでクッション体下面には離型剤が付着

にクッションの硬さを変えるには部分的に補強材をイン
サートしなければならないという欠点があった。However, since the cushion body obtained in this way is foam-molded in a mold, the mold release agent adheres to the bottom surface of the cushion body.
In addition to the drawback that it produces a scraping sound due to friction with the spring, since it is foamed with a single urethane formulation, reinforcing material must be inserted in some areas to change the firmness of the cushion. There were drawbacks.

ション部材を舷挿させたことを特徴とする。The present invention aims to provide a method for manufacturing a cushion body that eliminates the above-mentioned drawbacks, and includes applying a surface material to the inner surface of a mold for forming a foam layer having a hollow portion in a portion corresponding to the seat portion; A foamable synthetic resin liquid is charged into the mold corresponding to the area where the foam layer will be formed, and in the area where the hollow area is to be formed, the surface material is compressed using the upper and lower molds to form a hollow area. The present invention is characterized in that a cushion body is obtained in which a surface material is laminated on a foam layer, and a cushion member having substantially the same shape as the hollow portion is inserted into a hollow portion of the cushion body.
以下本発明の一実施例を図面に基ずし、て説明する。An embodiment of the present invention will be described below based on the drawings.
第１図に示すように、下型１内に表面材２を戦遣し、つ

縮するようにして下型１と合せて加熱発泡させ、加熱発
泡後型を冷却して成形体を取りだす。As shown in FIG. 1, the surface material 2 is placed inside the lower mold 1, and then the foamable synthetic resin liquid 3 is charged onto the surface material 2 corresponding to the concave portion of the lower mold 1. A molding agent is not applied to the part that contacts the surface material 2, but a mold release agent is applied to the part that will come into contact with the foam layer.The upper mold 4 is used to compress the surface material with the upper mold convex part 6. The mold is heated and foamed together with the lower mold 1, and after heating and foaming, the mold is cooled and the molded product is taken out.

レタンからなるものが好ましいが、Ｓバネと当る部分が
離型剤が付着していないように切断したものであるなら
畝質モールドウレタンであってもよい。As shown in FIGS. 2 and 3, the obtained molded body has the surface material 2 laminated on the upper surface of the foam layer 5, which has a rectangular hollow part 7 reaching the surface material 2 in the part corresponding to the seat part. , surface material 2
A cushion body is obtained in which a layer 8 in which the surface material is impregnated with foamed synthetic resin is formed on the surface where the foam layer 5 and the foam layer 5 are in contact with each other. Next, a cushion member 9 having substantially the same shape as the hollow part 7 is fitted with iron into the hollow part 7 of the cushion body and attached thereto. The cushion member 9 of the present invention is preferably made of European slab urethane or cold-cured urethane to which no mold release agent is attached, but the part that contacts the S spring is cut so that no mold release agent is attached. If it is a material, it may be a ridged molded urethane.
上記実施例においては、表面材２と当援する上型部分に
は離型剤が塗布されていないが、これは必ずしもこのよ
うにする必要はない。In the above embodiments, the upper mold part that supports the surface material 2 is not coated with a mold release agent, but this is not necessarily necessary.

明の方法に於いて、上型と下型とで表面材を圧縮するの
は、座部への発泡性合成樹脂の浸み込みを防止するため
であり、例えば表面材を約１／２の厚みに圧縮するよう
にすればよい。Furthermore, even if it is necessary to avoid adhesion of the mold release agent to the surface material 2, the mold release agent may also be applied to the mold part, and another material may be interposed between it and the surface material. It's okay. In the method of the present invention, the purpose of compressing the surface material with the upper mold and the lower mold is to prevent the foamable synthetic resin from seeping into the seat.For example, the surface material is compressed by about 1/2. It should be compressed to a thickness of .
クッション部材は中空部と必ずしも同一形状でなくとも
、少くとも腰掛けた場合に不快な異和感を感じない程度
の略同一形状のものであればよい。The cushion member does not necessarily have to have the same shape as the hollow portion, but may have substantially the same shape as the one that does not make the user feel uncomfortable when sitting on the seat.
本発明で使用する表面材としては、容易に所定の形状に
裁断でき、しかも表面フィーリングのよい可榛‘性材料
が適している。As the surface material used in the present invention, a flexible material that can be easily cut into a predetermined shape and has a good surface feel is suitable.

れる。For example, a flexible foam can be used, but a flexible material such as soft slab urethane is particularly preferred because it has excellent cushioning properties and surface feel. Moreover, such a surface material may cover the entire side surface of the inner surface of the mold, instead of covering only a part thereof as in the above embodiment. Examples of the foamable synthetic resin liquid that can be used in the present invention include polyurethane, phenol resin, and urea resin.
本発明の製造方法により得られるクッションは、自動車

得ることが可能となる。As described above, according to the manufacturing method of the present invention, the frame line under the cushion and the part that contacts the S spring are not heated and foamed using a mold release agent, so there is no rubbing noise due to friction with the S spring. Almost no oxidation occurs, and the back of the surface material other than the part corresponding to the seat is hard because a layer impregnated with foamed synthetic resin is formed, so the cushion is different from the seat and surrounding areas. The hard surrounding area provides a sense of hold and prevents deformation, and since the surface is covered with a single sheet of material, it can be You get no cushion. Furthermore, if cold cure urethane is used as a cushion member, a cushion with even better cushioning properties can be obtained, and if slab urethane is used, weight reduction can be achieved, so a cushion suitable for the purpose of use of the cushion can be obtained. becomes possible.
