【発明の詳細な説明】 （産業上の利用分野） 本発明は一つには、表皮体の構造に関するものであ
り、詳細には自動車内装品や家具等の部品として使用さ
れる表皮体であって縫製感のある表皮体に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates in part to a structure of a skin, and more particularly, to a skin used as a part of an automobile interior part or furniture. The present invention relates to a skin body having a feeling of sewing.
そして、今一つの発明は上記の表皮体を用いた発泡成
形品に関するものである。Another invention relates to a foam molded article using the above-mentioned skin.
（従来技術） 近年自動車内装品、例えばインストルメントパネル、
ヘッドレスト、アームレスト、ドアトリム、シート等の
分野において、需要者の高級化指向の高まりからその表
皮体として縫製加工されたものの要求が強い。(Prior art) In recent years, automobile interior parts such as instrument panels,
In the fields of headrests, armrests, door trims, seats, and the like, there is a strong demand for those that have been sewn as their skins due to the growing tendency of consumers to upgrade.
ところが、上記した自動車内装品の多くは複雑な曲面
を基調とした形状であり、その形状に完全に合致した表
皮体を縫製加工することは困難である。However, many of the above-mentioned automobile interior parts have shapes based on complicated curved surfaces, and it is difficult to sew a skin body that perfectly matches the shape.
また、縫製表皮体を一体発泡成形の表皮体として使用
する場合発泡成形時にそのつなぎ目より発泡原料が溢れ
だし成形が困難であるばかりでなく、その一体発泡成形
品を長期にわたって使用した時、縫製糸が伸びたり縫製
孔が拡大し中の発泡体があらわになる。Further, when the sewn skin is used as the skin of the integral foam molding, not only is the foaming material overflowing from the joint at the time of the foam molding and molding is difficult, but also when the integral foam molded article is used for a long time, the sewing thread And the sewing hole is enlarged, and the foam inside is exposed.
即ち、縫製によりシート状の素材を結合する時通常第
６図のように素材の表面（１）（２）を重ね合せて糸

ンフォーム等の発泡原料が充填されるが、この時の発泡
圧によって先の糸（３）による接合部（６）が広がり、
ウレタンフォームが当該接合部から外部へ溢れ出てしま
う。That is, when joining sheet-like materials by sewing, usually, as shown in FIG. 6, the surfaces (1) and (2) of the materials are overlapped and sewn once with a thread (3), and then each material (1) (2) Turn the end of the material into a loop to make each material a thread (4) (5)
Suture again. The skin body thus manufactured is set in a foaming mold together with the core body and is filled with a foaming material such as urethane foam. At the foaming pressure at this time, the joint ( 6) spread,
The urethane foam overflows from the joint to the outside.
そこで、この欠点を解決するため、本来的に一体に表
皮体を成形し、成形後に縫製に似せて第６図の（４）
（５）に相当する部分にミシンにより糸を挿入する手段
が提案されている（特公昭63−65486号）。Therefore, in order to solve this drawback, the skin is essentially integrally formed, and after forming, the skin is made to resemble the sewing, as shown in FIG.
A means for inserting a thread into a portion corresponding to (5) by a sewing machine has been proposed (Japanese Patent Publication No. 63-65486).
（発明が解決しようとする課題） 従来技術の表皮体および発泡成形品は先に問題となっ
た接合部（６）が存在しないため発泡層が溢れ出した
り、外から見えたりする欠点はない。しかし、その表皮
の外観は接合部（６）に糸がないこと、および当該部分
が糸で接合されていないことから縫製特有の突っ張り感
がなく実際の縫製品には程遠いものであった。(Problems to be Solved by the Invention) The skin and the foam molded article of the prior art do not have the defect that the foamed layer overflows or is visible from the outside because the joint (6), which has been a problem, does not exist. However, the appearance of the skin was far from an actual sewn product because there was no thread at the joint portion (6) and the portion was not joined with the thread, and there was no sense of tension peculiar to sewing.
そこで、本発明は従来技術の係る欠点に着目し、より
現実の縫製に近い表皮体および発泡成形品を提案するこ
とを目的とする。Then, the present invention pays attention to the shortcomings of the prior art, and an object of the present invention is to propose a skin body and a foam molded product which are closer to actual sewing.
（課題を解決するための手段） しかして上記する目的を達成するための請求項１の発
明の特徴は、製品の外形形状に合致させて成形された表
皮体であって、その一部に内側に折り返された凹部を有
し、該凹部の連続した表皮体は互いに縫合されているこ
とを特徴とする表皮体にある。(Means for Solving the Problems) A feature of the invention of claim 1 for achieving the above-mentioned object is a skin body formed to conform to the outer shape of a product, and a part of the skin body has an inner surface. And a continuous skin member of the concave portion is sewn to each other.
また、請求項３の発明の特徴は表皮体、発泡層、芯体

形形状に合致させて成形され、かつその一部に内側へ折
り返された凹部を有し、該凹部の連続した表皮体は互い
に縫合されたものであることを特徴とする発泡成形品に
ある。A feature of the invention according to claim 3 is that, in a foam molded article in which a skin body, a foam layer, and a core body are laminated, the skin body is formed so as to conform to the outer shape of the product, and a part thereof is folded inward. The foamed molded product is characterized in that it has a concave portion, and the continuous skin body of the concave portion is sewn to each other.
本発明の表皮体は連続して一体に成形されたものであ
り、どの部分にも切目はない。そして凹部の内側で互い
に縫合されているため外観上、当該糸目は見える。The skin of the present invention is formed continuously and integrally, and there is no cut in any part. And since it is stitched together inside the recessed part, the thread is visible in appearance.
更に、現実に表皮体の各部分は上記糸によって結合さ
れているため、表皮体に発泡体を充填した時縫製独特の
突っ張り感が得られる。Furthermore, since each part of the skin is actually connected by the thread, when the skin is filled with the foam, a unique feeling of tension is obtained.
