に導き、メインパッドウレタンフオーム用原料を注ぐ。(Prior Art) Seats S of vehicles such as automobiles are increasingly having grooves 2 formed on their surfaces, as shown in FIG. Such vehicle seats are usually finished by a method called integral skin foam molding. This skin-integrated foam molding will be explained with reference to FIGS. 5 to 8.
First, a sheet of urethane slab foam 4 is laminated on Noah 1 Rick) 3 is manufactured. In this case, the laminating means is adhesive or heat fusion. Furthermore, before setting in the mold 8, a plurality of suitably cut pieces are sewn together to form the skin material 1 that matches the surface shape of the seat. This is placed in the mold 8 with the skin 3 side facing the molding surface. Thereafter, the nozzle 13 is guided above the mold 8, and the raw material for the main pad urethane foam is poured into the mold.

表皮３とメインパッド１７とが一体化された表皮一体発
泡成形シート（以下、成形シートという）１２が得られ
る（第８図参照）。Then, the main pad 17 is integrally molded by closing the upper mold 9 and curing the foam. When the mold is opened in this manner, a skin-integrated foam molded sheet (hereinafter referred to as molded sheet) 12 in which the skin 3 and the main pad 17 are integrated is obtained (see FIG. 8).
ところで、上記の方法によって表面に溝２形状を施すに
は、ピース相互の縫い合わせ部分（溝形状を施すべき部

表皮材１は特に凸部６の根元部分に密着させておく必要
がある。密着状況が不完全であると、溝幅が不均一にな
る等、所望とする溝形状が得られないこととなるからで
ある。By the way, in order to form the groove 2 shape on the surface by the above method, the stitched parts of the pieces (the area where the groove shape is to be applied) are made to match the convex portion 6 formed on the molding surface of the mold 8. This method has been adopted. in this case,
The skin material 1 must be kept in close contact with the root portion of the convex portion 6 in particular. This is because if the adhesion is incomplete, the groove width will become non-uniform and the desired groove shape will not be obtained.
従来、密着性を確保するための手段として、第９図から
第１１図に示すような方法が知られている。第９１１の
ものは、クリップ１４によって挟みつける方法である。Conventionally, methods shown in FIGS. 9 to 11 are known as means for ensuring adhesion. The 911th method is a method of clipping with clips 14.
第１０図のものは成形面にいわゆるマジックテープ１５

法である。また、第１１図のものは両面接着チー１１６
によって成形面に貼り付は固定する方法である。The one in Figure 10 has so-called Velcro tape 15 on the molding surface.
This is a method in which the epidermis 3 is attached by pasting the skin. In addition, the one in Figure 11 is a double-sided adhesive 116
Pasting to the molding surface is a method of fixing.
（発明が解決しようとする課題）
しかし、上記の３つの方法はいずれも次のような問題点
がある。(Problems to be Solved by the Invention) However, all of the above three methods have the following problems.
第９図の方式は、クリップ１４を含んだままメインパッ

ン性を損ねる原因となる。In the method shown in FIG. 9, the main pad 17 is molded while containing the clip 14, so the clip 14 is left behind inside the product, which gives a foreign body feeling and impairs cushioning properties.
第１０図の方式は、いわゆるマジックテープ１５によっ
て接着される表皮３は、その種類が限られており、使用
対象となる表皮の範囲を狭める。In the method shown in FIG. 10, the type of skin 3 that is adhered by so-called Velcro tape 15 is limited, and the range of skin that can be used is narrowed.
加えて、テープ１５を剥がした後に表皮３が毛羽立つ、
という問題点もある。In addition, after peeling off the tape 15, the epidermis 3 becomes fluffy.
There is also a problem.
また、第１１図の方式の場合であれば、成形の都度両面
接着チー１１６を貼り付ける手間があり、作業性が良く
ない。さらに、両面テープ１６が消耗品となってコスト
高を招く。Further, in the case of the method shown in FIG. 11, it is laborious to attach the double-sided adhesive chip 116 each time molding is performed, and the workability is not good. Furthermore, the double-sided tape 16 becomes a consumable item, leading to increased costs.
そこで、本発明は作業性に優れ、外観品質が良好な製品

としたのである。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a vehicle of a type in which a pad material is laminated by integral foam molding on the back side of a skin material, and a predetermined groove is formed on the surface of the skin material. In the molding sheet, a protrusion of a predetermined height is provided on the molding surface of the foam mold at the location where the groove is to be formed, and the protrusion is formed into a comb-like shape that opens upward; An insertion part that can wrap around the protrusion is formed in the skin material, and the opening side of the insertion part is basted at a pitch that does not interfere with the comb teeth of the protrusion. After narrowing it down appropriately, it was decided to set the skin material in the mold by inserting the insertion part into the convex part in a tight state.
（実施例）
以下、本発明方法を具体化した実施例を図面にしたがっ
て詳細に説明する。(Example) Hereinafter, an example embodying the method of the present invention will be described in detail with reference to the drawings.

れている。FIG. 3 shows a groove 2 of the skin material 1 in a vehicle seat.
This shows the part where . The skin material 1 is of a known type, and has a two-layer structure consisting of a skin 3 whose surface is brushed and a urethane slab form 4 that falls on the back surface. The skin material 1 is three-dimensionally sewn by sewing together the ends of a plurality of pieces with sewing thread 5 so that the entire sheet has a predetermined shape.

７の開口側が適宜引き締められる。Before the skin material 1 is transferred to the molding process, the sewn portion of the skin material 1 is picked up toward the back side along the sewn edges and to a height sufficient to wrap around the entire convex portion 6, which will be described later. (See Figure 3). Furthermore, the opening side of the insertion part 7 has a relatively large pitch (10 to 20
Stitching 10 is performed at m-pitch), and the opening side of the insertion part 7 is tightened appropriately.

小さめに設定されている。FIG. 2 shows the area around the convex portion 6 on the lower mold 8 side of the foaming mold 8.9. The protrusions wA6 are arranged at respective molding locations of the groove portion 2 on the molding surface. Each has a slit 11 that is erected in a plate shape and opens upward.
are provided at predetermined pitches to form a comb-teeth shape. however,
The pitch of the comb teeth is set smaller than the pitch of the sewing 10 in the sewing.

セットされる。Now, when the skin material 1 is set in the mold 8, each insertion part 7 of the skin material 1 is inserted into the corresponding convex part 6 and fixed, so that the skin material 1 is brought into close contact with the molding surface. When inserting the insertion part 7 into the convex part 6, the thread of the basting stitch 10 enters into each slit 11 of the convex part 6 at an appropriate pitch, and the insertion part 7 is especially sewn into the convex part by the basting stitch 10. The part 6 is set in a state where its adhesion to the base is ensured.

製品が得られる。Thereafter, urethane resin is injected in the same manner as before, and the mold is closed. When the urethane solidifies after a predetermined period of time, the mold is opened and the molded sheet 12 is taken out. The thread of the basting stitch 10 is exposed from the opening of the groove 2 of the taken-out molded sheet 12, so if it is necessary to remove it, cut it in places (approximately 100 to 200 u + pitch) and remove this thread. Pull it out. As a result of the thus obtained molded sheet 12 having good adhesion to the roots of the convex portions 6,
It is possible to obtain a product in which the groove width of the groove portion 2 is substantially uniform, and a product with excellent appearance 1 can be obtained.
発泡成形工程が完了した成形シート１２は次工程へ移送
され、シートフレームへの組み付けがなされる。The molded sheet 12 that has undergone the foam molding process is transferred to the next process and assembled into a seat frame.
なお、仕付は縫い１０の糸は外観上、とくに支障がなけ
れば切断するだけで、あるいはそのまま放置しても良い
。In addition, for sewing, the thread for sewing 10 may be simply cut or left as is if there is no particular problem in terms of appearance.

良い。(Effects of the Invention) As is clear from the above description, according to the present invention, the opening of the insertion portion is tightened by sewing before being inserted into the foam mold, so that the convex It is possible to insert the device into the mold while keeping it in close contact with the base of the part. As a result, the groove portion of the molded product has a substantially uniform width of m. Moreover, the work efficiency is good because the preparatory work before molding is as simple as sewing and sewing.

。In addition, since the removable thread is used as a means for ensuring adhesion, foreign matter does not remain inside the sheet after molding as in the case of FIG. 9, and the cushioning properties of the sheet are ensured. Furthermore, since the quality of the epidermis is not deteriorated, such as by causing the epidermis to become fluffy, the appearance quality is maintained.
