を一体化するかの手段が採られている。DETAILED DESCRIPTION OF THE INVENTION Conventionally, vehicle parts, furniture, etc. using synthetic resin foams have been extremely widely used. A skin material is attached to this foam, but generally the skin material is placed in a mold and a foaming stock solution is injected into it to integrate it, or it is foamed in a mold called integral skin foam. The methods used include forming the skin at the same time while foaming the stock solution, or forming the foam into a sheet and then integrating the skin material with an adhesive.
近年になって、特に薄層の発泡体シート表面に表皮材を
接着させた積層体を使用し、これを製品基体表面に貼り
付けて感触性を増し、豪華さを現わす製品が多くなって
きた。In recent years, there has been an increase in the number of products that use laminates in which a skin material is adhered to the surface of a particularly thin foam sheet, and this is attached to the surface of the product base to increase the tactile feel and make it look luxurious. Ta.

ン等で縫製された被覆材をかぶせて製品化していた。For example, when it comes to vehicles, there are doors, ceilings, dashboards, armrests, console boxes, etc.
Among these, relatively flat areas such as the inner surface of a door can be dealt with by simply pasting a laminate made of a foam sheet with a skin material adhered to it as described above.
It is difficult to attach this directly to armrests with edges, etc., so generally a foam sheet is first attached to the surface of the armrest product base, and then a covering material sewn with a sewing machine etc. is covered. .
第４図〜第６図はこの従来の手段に基づくアームレスト

た状態での切断斜視図である。4 to 6 illustrate a part of the manufacturing process of an armrest based on this conventional method, and FIG. 4 shows a cutaway perspective view of the foam sheet 2 attached to the armrest base 1. It is a diagram.

基体１のエツジの稜線部（矢印Ａ）を巧く表すことが難
しく、一般にはこの稜線部に添って２枚の被覆素体を縫
い合わせた被覆材が用いられるが、この縫製が極めて工
数のかかる作業であった。The product is then completed by covering this with a covering material 3 sewn using a sewing machine, etc. However, when covering, it is particularly difficult to clearly represent the ridgeline (arrow A) of the edge of the armrest base 1, so generally speaking, A covering material is used in which two covering elements are sewn together along this ridgeline, but this sewing is extremely labor-intensive work.
第５図は縫製の際の２枚の被覆素体３１．３□の展開図
であって、図中４１．４□は織り目であり、縫い目５に
対して斜めに織り目が入っている例である。また符号６

is the seam allowance.

く手間がかがるものであった。The sewing work of the covering element 31.3□ is not simply a matter of sewing them together (the weave 41

化させる必要があった。In other words, it goes without saying that it is necessary to carefully sew the weaves 41, 42, etc. so that they match, but it is also necessary to make cuts 7 in the seam allowance 6 in advance to match the weaves 41, 4, etc. Therefore, it was necessary to change the size, depth, etc. of this cut 7, particularly in response to the condition of the edge of the product substrate.
更に縫製作業を完了した後であっても、第６図（イ）に

被覆材３の表面を平にする作業が行われてきた。Furthermore, even after the sewing work is completed, it is not possible to leave the seam allowance 6 as it is as shown in Figure 6 (a), and it cannot be used with adhesive or adhesive as shown in (b). (not shown), etc., to the back side of the covering material and glue it.
Work has been carried out to flatten the surface of the covering material 3.

のよいものばかりではなかった。Even after the sewing work is completed, the covering material does not always have a good appearance, as the raised state of the cloth, such as velvet, may become folded due to the running of the sewing machine.

要していた。Furthermore, when covering the foam 2 with the covering material 3, the foam 2 has a large surface frictional resistance, and it requires considerable skill to successfully cover the covering material 3 on a particularly deep product substrate. Ta.
（目的）
本発明は以上のような欠点を解決せんとして開発された
ものであって、発泡体シートに表皮材を接着した被覆材
をそのまま製品基体表面上に添設することを目的とした
ものである。(Purpose) The present invention was developed to solve the above-mentioned drawbacks, and its purpose is to attach a covering material made of a foam sheet with a skin material adhered to the surface of a product substrate as it is. It is.
（構成）
本発明は以上の目的を達成するために次のような構成を
採用したものである。(Structure) In order to achieve the above object, the present invention employs the following structure.
即ち、柔軟性を有する合成樹脂発泡体シートに表皮材を
添設して積層体となし、製品基体のエツジの稜線部に対

線部とを合せて折り曲げることを特徴と１する折り曲げ
ラインをもった被覆材の構造にかがるものである。That is, a skin material is attached to a flexible synthetic resin foam sheet to form a laminate, and the laminate is pressurized and heated to correspond to the ridgeline of the edge of the product base, and then passed through a heat-sealing line. The structure of the covering material has a bending line, characterized in that the heat-sealed line and the ridgeline of the product base are bent together to form a covering material.
ここでいう柔軟性を有する合成樹脂発泡体としては、特

ィン発泡体やポリ塩化ビニル発泡体も使用可能である。As the flexible synthetic resin foam referred to here, flexible polyurethane foam is particularly preferred, but semi-rigid polyurethane foam is also good, and polyolefin foam and polyvinyl chloride foam can also be used. It is.
そして表皮材も特に限定はなく、各種繊維からなる織布
、不織布、更には塩化ビニル製のものでもよく、前記し
た発泡体と熱溶着するものであれば制限はない。The skin material is not particularly limited, and may be a woven fabric or non-woven fabric made of various fibers, or even one made of vinyl chloride, and is not limited as long as it can be thermally welded to the foam described above.

に全くない着想に基づいている。(Function) The main technology of the present invention is a heat fusion technology, and this technology integrates a synthetic resin foam sheet and a cloth material, and utilizes the line during the heat fusion to create a seat for a vehicle, for example. This is a technique used to form patterns on the surfaces of seats and backs of products such as the United States, but the present invention applies this heat-sealing line to the ridgeline of the sharp-edged product substrate, especially the bent portion. It is based on an idea that has never existed before.
第１図は本発明の基本となる発泡体シート１１と表皮材

る。That is, in FIG. 2, the foam sheet 11 is softened by pressure and heat treatment and is fused to the skin material 2, forming a heat fused line 13 here. At this heat-sealing line 13, the two are quite firmly integrated; in other words, the foam sheet 11 is divided into left and right parts at this part, and the laminate is formed along this heat-sealing line 13. It can now be easily bent.
（具体例）

そして、第４図に示す車両における合成樹脂製のアーム
レスト基体のエツジの稜線部Ａに対応してこの積層体を
加圧・加熱した。Then, this laminate was pressurized and heated in a manner corresponding to the ridgeline portion A of the edge of the armrest base made of synthetic resin in the vehicle shown in FIG.
この加圧幅は１．ｍｍであり、加熱条件は２０００Ｃで
１分間であった。This pressure width is 1. mm, and the heating conditions were 2000C for 1 minute.

The soft polyurethane foam sea hl 1 corresponding to mm is
Heat-sealed line 13 is integrally heat-sealed with the skin material 12 in a linear manner.
A covering material 3 was obtained in which a 3-dimensional structure was formed, and bending from this part was extremely easy.
第３図はここで得られた被覆材３を製品基体１に被せた
際の基体１のエツジにおける稜線部ａ近傍の一部拡大断
面図である。FIG. 3 is a partially enlarged sectional view of the vicinity of the ridgeline a at the edge of the substrate 1 when the coating material 3 obtained here is placed on the product substrate 1.
