本発明は、凹凸模様を有するシート表皮の製造
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for producing a sheet skin having an uneven pattern.

着することが行われている。2. Description of the Related Art In general, in vehicle seats, in order to maintain good sitting comfort and prevent slipping during braking, wading c is provided between a skin material a and a wading cover b, as shown in Fig. 1. Seat skin that has been sandwiched to maintain its shape in an uneven pattern is applied to a cushion form.

皮材ａとワデイングカバーｂをウエルダー溶着す
ることが知られている（実開昭56−25677号）。 Conventionally, when manufacturing this type of seat skin, the three materials are laminated by interposing wading c such as a polyurethane foam slab material in the middle layer of the skin material a and the wading cover b, and the laminated material is After placing the laminated material on the flat plate surface of the lower mold, the upper mold with an upright protruding blade that shapes the laminated material into an uneven shape presses it from the skin material side to the lower mold, and the skin material is compressed in the compressed part of the wading. It is known to weld the wading cover a and the wading cover b together (Utility Model Application Publication No. 56-25677).
発明が解決しようとする課題
然し、この上型と下型によるシート表皮では表

模様は大きな起伏は形成できないばかりでなく、
凹凸模様の凸部も丸く隆起するだけで所望形状に
形成できないから十分な滑り止め効果を発揮する
ことができない。Problems to be Solved by the Invention However, in the sheet skin formed by the upper mold and the lower mold, tension is applied to the skin material a as the skin material a is pressed by the protruding blade of the lower mold. Therefore, the skin material a compresses the wading c even at the bulging part and pushes it out toward the wading cover b.
As shown in FIG. 2, the tension of the skin material causes a loss in the undulations of the uneven pattern by a bulging amount h. Therefore, this uneven pattern not only cannot form large undulations, but also
The convex portions of the concavo-convex pattern cannot be formed into a desired shape because they are only rounded and raised, and therefore cannot exhibit a sufficient anti-slip effect.
この欠点は第３図で示すように表皮材ａに張力
を与えない所定形状に形成すると共に、その凸部
の形状に合わせてワデイングを押込みしかもワデ
イングカバーを扁平に保持させて表皮材と接合で
きれば除去することができる。 This drawback is solved by forming the skin material a into a predetermined shape that does not apply tension, as shown in Fig. 3, and by pressing the wadding in accordance with the shape of the convex part and holding the wading cover flat to join it to the skin material. It can be removed if possible.
茲において、本発明は第３図で示す如き起伏に

創意工夫したシート表皮の製造方法を提供するこ
とを目的とする。 An object of the present invention is to provide a method for manufacturing a seat skin that is ingeniously devised to form a seat skin that has an uneven pattern rich in undulations as shown in FIG.

形成するようにされている。Means for Solving the Problems In the method for manufacturing a seat skin according to the present invention, after forming the skin material into an uneven shape with the lower mold by bringing it into close contact with the uneven surface of the lower mold, the skin material is placed inside the lower mold. The wadding, which is stacked on top of the wading cover when installed, is placed on the lower mold as a flat plate of a constant thickness, and the wadding is pressed into the lower mold with the flat pressing surface of the upper mold that presses the wadding from the wadding cover side. Then, the bulging part of the wading formed by the concave surface of the lower mold is pushed into the recess of the skin material, and the wadding cover is pressed into the skin by the compressed part of the wading created by the convex surface of the lower mold and the flat pressing surface of the upper mold. The wading cover is welded to the convex surface of the material and held flat by the flat pressing surface of the upper mold, and the wading cover is used to back and support the wadding to form a relatively uneven pattern. It is like that.

るようになる。Function: In this sheet skin manufacturing method, the wading is pressed into the uneven surface of the lower mold using the pressing surface of the upper mold and pushed into the recesses of the skin material that have been formed into a predetermined shape, so that the wading can also be formed into a predetermined shape. Not, but
The wading material, which has a flat plate shape with a certain thickness, is pushed into the recess of the skin material, so the recess of the skin material can be held in a taut state, and the wading cover is held down by the flat pressing surface of the upper die. By bonding it to the skin material, it can be shaped into a flat shape that can withstand the expansion force of wading. Therefore, by backing and supporting the wading with a flat wading cover, the uneven pattern on the seat skin can be formed with large undulations, and the convex portions can be formed into a desired shape.

用いるとよい。 The seat skin formed by these upper and lower molds has a wading c interposed between the skin material a and the wading cover b, and when forming the sheet skin, at least the skin material a is not laminated to the wading c and is separated. The body is treated as is. The skin material a and the wading cover b are made of materials that can be welded by high-frequency welding, such as PVC, and the wading c is made of polyurethane foam, slab material for high-frequency welding, etc., and is shaped like a flat plate with a certain thickness. It is preferable to use a material that is formed to have a high elongation rate.

ーｂを扁平状に圧着固定させる。 Using each of these materials, first, the skin material a is molded into an uneven shape by closely contacting it along the uneven surface of the lower mold X. The peripheral edge of the skin material a is clamped by clamps P installed on the lower mold X, heated with a heater H to soften it, and drawn into the inside of the lower mold X by the suction of the vacuum V, so that the uneven surface of the lower mold X It can be formed into an uneven shape by adhering it closely along the surface (Fig. 4a,
b). The skin material a formed in the uneven shape remains installed inside the lower mold X, and then the wadding c having a constant thickness and the wadding cover B placed on the upper side are placed on the lower mold X. The mounting can be carried out by setting it in advance after the skin material a is formed or before the skin material a is vacuum-formed using a vacuum. Further, it is sufficient to assemble the wading c with a size that covers the uneven surface of the lower mold X (see FIG. 4c). After the wading c and the wading cover b are placed, they are press-fitted into the lower mold X by the pressure accompanying the downward movement of the upper mold Y. By this pressing, the bulging part of the wading c corresponding to the concave surface of the lower mold X is pushed into the concave part of the skin material a to maintain a predetermined shape,
Furthermore, the wading cover b is compressed by the compressed part of the wadding c corresponding to the convex surface of the lower mold X, and the skin material a is pressed between the lower electrodes x 1 , By welding the convex surfaces of the wading cover b, the wading cover b is fixed in a flat shape.

なる。 In the sheet skin thus obtained, the skin material a is preformed into an uneven shape corresponding to the desired uneven pattern, and the wading c is pushed into the recesses of the skin material a to form a predetermined shape. Since the thick, flat plate-shaped wading c is press-deformed and pushed into the recesses of the skin material a, the convex portions with the concave-convex pattern can be formed under tension. At the same time, the wading cover b is welded to the convex surface of the skin material a and crimped and fixed in a flat shape.
By backing and supporting the wading c, a pattern with large undulations can be formed in a predetermined shape.

As shown in the figure, a slide base S is attached to the high-frequency welding machine W, and a lower die x is placed on the slide base S so that it can slide in and out. After performing the softening treatment, wading, and placing a wading cover, it is possible to use a device that is carried directly under the upper die Y of the high-frequency welding machine W. Furthermore, if the slide base S is configured with a turntable, the lower die can be carried in and out of the high-frequency welding machine from several locations. Further, as a welding method, in addition to high-frequency welding, a heater heating type or an ultrasonic welding type can be used, and a welding agent can also be used at the welding location.
