席体が得られる。 Next, as shown in FIG. 2, after the skin 3 is formed, the upper mold 2 is raised upwards (not shown) and the skin 3 is formed.
Spray the adhesive onto the required areas. On the other hand, a depositing material is also sprayed on the portion of the urethane mold (cushion material) 6 corresponding to the seating part, and the urethane mold 6 is crimped to the skin 3 by pressure P (actually a distributed load on the urethane mold 6) as shown in FIG. let After adhesion, the skin 3 is removed from the fixture 5 and taken out to obtain a seat body made of urethane mold 6 with the skin 3 attached.

起す材料或は加熱すると物性又は外観が劣化する
材料などの場合は、第１図及び第２図の成形凹凸
面によつて正確に表皮３を成形できない欠点があ
る。 Although the skin 3 explained above is thermoplastic, if it is a material that is not thermoplastic, a material that shrinks due to heat, or a material that deteriorates in physical properties or appearance when heated, the molding unevenness shown in FIGS. 1 and 2 may be used. There is a drawback that the skin 3 cannot be formed accurately depending on the surface.
次に本発明による表皮成形座席の製法について
の各実施例につき図面を参照して説明する。 Next, embodiments of a method for manufacturing a skin-molded seat according to the present invention will be described with reference to the drawings.
第４図は本発明による座席の断面を示すもの

要な凹凸部の表面積に等しい総面積の表皮３を下
型１の固定具５に取付けている。 FIG. 4 shows a cross section of the seat according to the present invention, showing that the skin 3 is along the line of the cross section of the molding surface of the lower mold 1 (it is not compression molded by the upper mold 2). . In this case, a skin 3 having a total area equal to the surface area of the uneven portion necessary for molding the lower mold 1 is attached to a fixture 5 of the lower mold 1.
更に詳しい説明をすると、第５図は第４図の下
型１のＸ矢視図で（固定具５は図示省略）、第５
図のＸ−Ｘ断面が第１図〜第４図の下型１の断面
を示す。 To give a more detailed explanation, FIG. 5 is a view of the lower die 1 in FIG.
The cross section taken along the line XX in the figure shows the cross section of the lower mold 1 shown in FIGS. 1 to 4.
第５図のX1−X1，X2−X2断面は図示省略して
あるがＸ−Ｘ断面形状の表面の延長線の長さとは
それぞれ異なる。第５図のＹ−Ｙ方向の断面或は
その他の方向の断面についても同様である。 Although the cross sections X 1 -X 1 and X 2 -X 2 in FIG. 5 are not shown, the lengths of the extension lines of the surface of the X-X cross section are different from each other. The same applies to the cross section in the Y-Y direction in FIG. 5 or the cross section in other directions.
表皮３はこのような下型１の成形面の各断面の
総延長と同じ長さで下型１の成形面（上型２も同

様にウレタンモールド６を接着させて完成する。 Figure 6 shows the seat body as seen from the X arrow in Figure 4. For example, the backs of both sides (the left side of the a-a line and the right side of the b-b line) are made of vinyl leather, and the body part in the center is made of fabric. The components having different materials and physical properties are connected by the a-a line and the bb line. In the conventional methods shown in FIGS. 1 and 2, since the elongation rates of vinyl leather and fabric are different, it is difficult to mold the positions a-a and b-b to match the predetermined positions of the urethane mold 6. According to the manufacturing method of the present invention, the above positions can be adjusted accurately. The next step in FIG. 4 is completed by bonding the urethane mold 6 in the same manner as in FIG. 3 described above.
以上で説明した如く本発明の表皮３は予め下型
成形面の表面の展開した総面積形状と等しく、例
えば裁断によつて製作したものである。 As explained above, the skin 3 of the present invention has the same total area shape as the developed surface of the lower molding surface, and is manufactured by, for example, cutting.

準じて異なるものである。 FIG. 7 shows an attempt to obtain the same effect by applying permanent residual strain due to tension in the material of the skin 3, without using the above-mentioned cutting. The skin 3 is fixed to the lower mold 1B by the fixture 5 at the outer periphery of the seated shape when molding is completed, and the upper mold 2B is lowered to lower the skin 3 to the dotted line position to stretch the skin 3. The shape of the upper mold 2B was explained for each cross section in Fig. 5 until the permanent residual amount of the skin 3 obtained the required length and total developed area of each cross section as described above for the skin even if the upper mold 2B was raised. It varies depending on the case.
次に表皮３を第４図の下型１に移し取り付け、
次が第３図と同じ工程となる。 Next, the skin 3 is transferred to the lower mold 1 in Fig. 4 and attached.
The next step is the same as that shown in Figure 3.

させて完成する。 In the above explanation, the bead 4 is fixed to the lower mold 1 by the fixture 5, but the manufacturing method shown in Fig. 8 does not have the bead 4, and the seat body's fillet 3a and gusset portion 3b are integrated. This is the case of one piece of epidermis 3. Furthermore, referring to FIG. 3, this corresponds to a method in which there is no bead 4 and gusset 3b, and the urethane mold 6 is bonded to the gusset 3a of one piece of the outer skin 3, and then the gusset 3b is joined to the gusset 3b. In this case or the 8th
In the example shown in the figure, there is no fixture 5, so the area around the skin 3 is free, and is inside from the outside of the molding surface of the lower mold 1 in Figure 8 (lower mold 1 in Figure 4 minus the fixture 5). The skin 3 is attached by sliding it onto the molded surface. Although not shown, the lower mold 1 in Figures 4 and 8
It is possible to fix it to the necessary part where the skin 3 contacts with Velcro or other methods, and then attach the skin 3 to this to prevent the skin from shifting. The next step is to complete the urethane mold 6 by adhering it according to the method shown in FIG.

更に正確な形状が得られる。 Even with the conventional method of heating the skin 3 shown in FIGS. 1 and 2, if the above methods are applied, it can be molded into a more accurate shape than before. Alternatively, the epidermis may be prepared using the conventional method of pressing the epidermis 3 with the upper die 2 of Figs. 1 and 2 without heating while keeping the epidermis 3 in tension as shown in Fig.
Alternatively, if the present invention is combined with a method in which the temperature of one or both of the upper molds is raised and the skin is sandwiched between the upper mold and the lower mold and heated, a more accurate shape can be obtained depending on the material of the skin 3. It will be done.

６の通気性は良好となる。 In FIG. 3, the skin 3 and the urethane mold 6 are bonded together, but although not shown, there is also a method of fixing the urethane mold 6 to the skin 3 by injecting and foaming a urethane stock solution instead of adhesion. In this case, the pressure P shown in FIG. 3 is the foaming pressure during urethane foaming to press the skin 3 against the lower mold 1. Although not shown in the drawings, the area type is one in which the shape of the seating part of the seat body is molded on the bottom of the foam mold or the bottom of the upper mold. In the above-mentioned adhesion, when the adhesive is sprayed in spots, the air permeability between the skin 3 and the urethane mold 6 will be good.

とが出来て上記第３図と同じ結果となる。 In each of the above embodiments, a case has been described in which the skin 3 adheres closely to the molding section of the lower mold 1, but this is not necessarily a necessary condition, and there may be a portion where the skin 3 is separated from the molding section of the lower mold. Also, when the urethane mold 6 shown in FIG. By using a skin having a total developed area smaller than the total area of the surface and a length shorter than the extension length of each cross section of the molding surface of the lower mold, the heating process and the compression process using the upper mold can be abolished or the heating process can be replaced. Even if it is abolished, the skin can stretch and follow the molding cross section during urethane mold crimping, resulting in the same result as shown in Fig. 3 above.
前記説明において、ウレタンモールド６として
説明したがウレタンモールドに限るものでなく他
のクツシヨン材であつてもよい。 In the above description, the urethane mold 6 has been described, but it is not limited to the urethane mold, and other cushion materials may be used.
第１図〜第４図、第７図、第８図の各図に於い
て上型、下型の位置を上下を反対にする製法もあ
る。 There is also a manufacturing method in which the positions of the upper mold and the lower mold are reversed in the respective figures of FIGS. 1 to 4, FIG. 7, and FIG. 8.
本発明は、座席体に限るものではなく、例えば
車両のドアパツド、アームレストその他の内装品
に或いは家具などにも応用できる。 The present invention is not limited to seat bodies, but can also be applied to, for example, door pads, armrests, and other interior parts of vehicles, or to furniture.

下させることができる。 According to the manufacturing method of the present invention, the heating process of the skin in the conventional manufacturing method is abolished, and depending on the material of the skin material and the shape of the molding, the step of compression molding the skin using an upper mold is also eliminated. Furthermore, there is no deterioration in the physical properties of the skin, the molded shape is accurate, and costs can be reduced.
また、従来のフアブリツクの裏側にビニールな
