【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、自動車用内装材等に使用される縫製表皮の
製造方法に関するものである。Description: TECHNICAL FIELD The present invention relates to a method for producing a sewn skin used for interior materials for automobiles and the like.
近年、自動車用内装品には高級品化指向により本物の
使用、又はより本物感のある表現が望まれてきておりダ
ッシュボード周りのパッドの表皮に本物の縫製品が使用
されているのもその一つである。In recent years, it has been desired to use genuine or more realistic expressions for automotive interior parts due to the trend toward luxury goods, and genuine sewing products are used for the skin of the pad around the dashboard. One.
表皮に縫製模様いわゆるステッチ模様を表現する方法
としてはスラッシュ成形又はメス引き真空成形により型
から転写する方法が用いられていたが、この方法では表
皮材と糸が同一材質、同一色である等から本物感に欠け
るという不満があった。As a method of expressing a so-called stitch pattern on the skin, a method of transferring from a mold by slash molding or scalpel vacuum forming was used, but in this method, the skin material and the thread are the same material, the same color, etc. I was dissatisfied with the lack of authenticity.
これに対し本物の皮又は本物感のある表皮を実際に手
で縫製加工すればより高級感が得られることから上記縫
製品が価格アップをある程度度外観して高級車に採用さ
れてきている。On the other hand, if a real leather or a genuine skin is actually sewn by hand, a higher-grade feeling can be obtained, and thus the above-mentioned sewn products have been used in high-end vehicles with a certain degree of price increase appearance.
第７図は縫製表皮を用いたパッドの要部斜視図である
が、図中に示す表皮１は従来次のような工程により製縫
されている。FIG. 7 is a perspective view of a main part of a pad using a sewn skin. The skin 1 shown in the figure is conventionally sewn by the following steps.
すなわち、まず第４図に示すように、型を用いて表皮
１の一部にＶ形の溝部10を形成する。次に第５図に示す
ように溝部10上端相互を上糸３、下糸４により合せ縫い
して合せ縫い部1cを形成する。That is, first, as shown in FIG. 4, a V-shaped groove 10 is formed in a part of the skin 1 using a mold. Next, as shown in FIG. 5, the upper ends of the groove portions 10 are sewn together with the upper thread 3 and the lower thread 4 to form a joint stitch portion 1c.
次に第６図に示すように表皮１の溝部10の突出側にシ
ール材７を当接し、合せ縫い部1cの両側で且つこれと同
一方向に表皮１とシール材７とを上糸５、下糸６で縫い
合せて重ね縫い部1d、1dを形成して製造される。Next, as shown in FIG. 6, the sealing material 7 is brought into contact with the protruding side of the groove portion 10 of the skin 1, and the skin 1 and the sealing material 7 are attached to the upper thread 5 on both sides of the seam 1c and in the same direction as this. It is manufactured by sewing together with the lower thread 6 to form lap stitch portions 1d, 1d.
そして上記重ね縫い部1d、1dを設けることにより引っ
張り等による合せ縫い部1cの破れが保護されるととも
に、パッド成形の際に発泡プラスチック、例えばウレタ
ンフォームの発泡時にこれが合せ縫い部1cの縫い目穴か
ら洩れて流出するのを防ぐことができるようにしてい
る。By providing the lap seams 1d, 1d, the tear of the joint seam 1c due to tension or the like is protected, and at the time of pad molding, when the foamed plastic, for example, urethane foam is foamed, this is cut from the seam hole of the seam 1c. It is designed to prevent leakage and outflow.
従来の技術で述べた上記方法の場合には、表皮、糸の
他にシール材が必要であるばかりではなく、シール材を
表皮と一緒に縫う場合にシール材を縫製部分に確実に位
置するようにするために両面テープ等で仮り固定する等
の工数が掛り、材料費、製造費共に増加し不経済であっ
た。In the case of the above-mentioned method described in the prior art, not only a seal material is required in addition to the skin and the thread, but also when the seal material is sewn together with the skin, the seal material is surely positioned on the sewn portion. In such a case, it takes a lot of man-hours such as temporary fixing with a double-sided tape or the like, and both material costs and manufacturing costs increase, which is uneconomical.
本発明の目的は上記のような欠点のない縫製表皮の製
造方法を提供することにある。An object of the present invention is to provide a method for producing a sewn skin which does not have the above-mentioned disadvantages.

も好ましい。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is an explanatory perspective view of a step of forming a groove in a skin according to the present invention, and 1 is a soft vinyl chloride thermoplastic material. The thickness of the skin 1 is 0.5 to 1.5
Although it may be about mm, it is most preferably about 0.8 mm from the viewpoint of strength and sewing.

り溝部８内の途中に対向して形成した折り目である。Reference numeral 8 denotes a substantially U-shaped groove provided on the skin 1 by vacuum forming or slash forming. As the molding method, slush molding is more preferable because of ease of groove formation. Reference numerals 9 and 9 denote folds formed in the groove 8 so as to face each other by a mold so that the skin 1 can be easily bent.

１の３枚重ね合せは可能である。FIG. 3 is an explanatory perspective view of the step of pushing and spreading the groove shown in FIG. 2 and overlapping stitching. The groove 8 having the seam 1a is pushed and bent at the folds 9 and 9, so that three skins 1 are stacked. The overlapped portions 1b, 1b are formed by sewing the inner side of the creases 9, 9 by 1 to 2 mm from both sides thereof with the upper thread 5 and the lower thread 6 in the direction of the joint stitch portion 1a. In the present embodiment, the folds 9 and 9 are provided in the groove 8 so that the groove 8 can be easily bent. However, without this, the groove 8 is pushed and the three skins 1 can be overlapped. .
