Description

本発明は、車両用内装部品の表皮カバーに関する。より詳しくは、袋状に形成された表皮カバーの内部でパッド原料を発泡させることにより表皮カバーの内部に一体的にパッドが成形される車両用内装部品の表皮カバーに関する。   The present invention relates to a skin cover for vehicle interior parts. More specifically, the present invention relates to a skin cover for vehicle interior parts in which a pad is integrally formed inside a skin cover by foaming a pad raw material inside the bag-shaped skin cover.

従来、袋状に形成された表皮カバーの内部で発泡樹脂のパッド原料を発泡させることにより表皮カバーの内部に一体的にパッドが成形されたヘッドレストがあった。かかるヘッドレストの表皮カバーは、従来、複数の表皮ピースを縫合して袋状に形成されていた。そのため、表皮ピースの縫い目部分からパッド原料が漏れやすく、その対策が講じられていた。下記特許文献１に記載の表皮カバーでは、表皮ピースを縫合するにあたり、起毛処理して毛羽立たせた帯状のシール材が縫い合わせられている。これにより、シール材の毛羽が糸と針穴の隙間を埋めるか或いは起毛が糸の周囲を囲うことによってパッド原料が漏れにくくなっている。また、下記特許文献２に記載の表皮カバーでは、表皮ピースをオーバーロック縫いにより縫合し、表皮ピースの裁断端部をも閉じ合わせて縫い目を開きにくくすることでパッド原料が漏れにくくなっている。   Conventionally, there has been a headrest in which a pad is integrally formed inside a skin cover by foaming a pad material of a foamed resin inside the skin cover formed in a bag shape. Conventionally, the skin cover of such a headrest has been formed into a bag shape by sewing a plurality of skin pieces. For this reason, the pad raw material easily leaks from the seam portion of the skin piece, and countermeasures have been taken. In the skin cover described in Patent Document 1 below, a band-shaped seal material that is raised and fluffed is sewn together when stitching the skin piece. As a result, the pad raw material is less likely to leak when the fuzz of the sealing material fills the gap between the yarn and the needle hole or the raised hair surrounds the yarn. Moreover, in the skin cover described in the following Patent Document 2, the pad raw material is less likely to leak by stitching the skin piece by overlock stitching and closing the cut end portion of the skin piece to make it difficult to open the seam.

特開２００５−３４２１２号公報JP 2005-34212 A 特開平９−１６８４４９号公報JP 9-168449 A

しかしながら、縫製部分にシール材を追加設定したり、表皮ピースをオーバーロック縫いで縫合したりすると、縫製部分が固くなり、パッド原料を発泡させた際に皺が生じやすかった。   However, when a sealing material is additionally set in the sewing portion or the skin piece is stitched by overlock stitching, the sewing portion becomes hard and wrinkles tend to occur when the pad raw material is foamed.

そこで、本発明は、パッド原料が漏れ出しにくく、且つ皺の生じにくい車両用内装部品の表皮カバーを提供することを課題とした。   Then, this invention made it the subject to provide the skin cover of the interior component for vehicles which a pad raw material does not leak easily, and a wrinkle does not produce easily.

本発明は、上記課題を解決するために次の手段をとる。
第１の発明は、袋状に形成された表皮カバーの内部でパッド原料を発泡させることにより表皮カバーの内部に一体的にパッドが成形される車両用内装部品の表皮カバーであって、袋織により二重組織部の周囲に一重組織部が一体形成されて袋状に形成されており、前記二重組織部に隣接する前記一重組織部の境界部位は朱子組織で構成されていることを特徴とする。 The present invention takes the following means to solve the above problems.
A first invention is a skin cover for an interior part for a vehicle in which a pad is integrally formed inside a skin cover by foaming a pad raw material inside the bag-shaped skin cover. A single tissue part is integrally formed around the double tissue part to form a bag, and a boundary part of the single tissue part adjacent to the double tissue part is composed of a satin tissue. To do.

袋織とは、二枚の織物組織が重複した二重組織部と、該二重組織部を構成する二枚の織物組織が繊維を互いに織り込まれて一枚の織物組織として集約された一重組織部とを一枚の織布中に形成し、二重組織部の周囲に一重組織部を形成することにより二重組織部を構成する二枚の織物組織の周囲を連結して中空袋状とする織り方である。第１の発明の車両用内装部品の表皮カバーによれば、袋織により袋状に形成されており、二重組織部を構成する二枚の織物組織が一重組織部として集約されて連結されているため、該二枚の織物組織間に隙間が生じにくく、パッド原料が漏れ出しにくい。また、前記二枚の織物組織が縫製に依らず接続形成されており、針穴が形成されていないため、針穴からパッドが漏れ出すこともない。そして、二重組織部に隣接する一重組織部の境界部位が柔軟な朱子組織で形成されているため、パッド原料を発泡させた際に前記二枚の織物組織の境界に皺が生じにくい。   The bag weave is a double tissue portion in which two woven fabric structures are overlapped, and a single tissue portion in which the two woven fabric structures constituting the double woven fabric portion are woven into each other and aggregated as a single woven fabric structure. Are formed in a single woven fabric, and a single tissue portion is formed around the double tissue portion, thereby connecting the periphery of the two fabric tissues constituting the double tissue portion into a hollow bag shape. How to weave. According to the skin cover of the vehicle interior part of the first invention, it is formed into a bag shape by bag weaving, and the two fabric structures constituting the double tissue part are aggregated and connected as a single tissue part. Therefore, a gap is hardly generated between the two woven fabric structures, and the pad raw material is not easily leaked. Further, since the two fabric structures are connected and formed without depending on the sewing and the needle hole is not formed, the pad does not leak from the needle hole. And since the boundary site | part of the single tissue part adjacent to a double structure part is formed with the flexible satin structure, when a pad raw material is made to foam, a wrinkle does not arise easily in the boundary of the said 2 fabric structure.

第２の発明は、上記第１の発明に記載の車両用内装部品の表皮カバーであって、前記一重組織部は、朱子組織で構成される前記境界部位の周囲が平組織で構成されていることを特徴とする。   2nd invention is the skin cover of the interior part for vehicles as described in the said 1st invention, Comprising: The surrounding of the said boundary site | part comprised by a satin structure is comprised by the flat structure in the said single tissue part. It is characterized by that.

第２の発明によれば、柔軟な朱子組織の周囲が丈夫な平組織で形成されているため、パッド原料の発泡に際して二重組織部を構成する二枚の織物組織を裂く作用力が生じても、表皮カバーの形状を保持しやすい。   According to the second aspect of the invention, since the periphery of the flexible satin structure is formed of a strong flat structure, an action force that tears the two fabric structures constituting the double structure part is generated when the pad raw material is foamed. Even the shape of the skin cover is easy to hold.

第３の発明は、上記第１の発明または第２の発明に記載の車両用内装部品の表皮カバーであって、前記一重組織部の境界部位を構成する朱子組織は８枚朱子であることを特徴とする。   3rd invention is a skin cover of interior parts for vehicles given in the above-mentioned 1st invention or 2nd invention, Comprising: The vermilion structure which constitutes the boundary part of the above-mentioned single organization part is eight sheets Features.

第３の発明によれば、一重組織部の境界部位を構成する朱子組織がより柔軟で方向性のない８枚朱子であるため、皺が生じにくく、曲線形状への追従性が高められる。   According to the third aspect of the invention, since the vermilion tissue constituting the boundary portion of the single tissue portion is the more flexible and non-directional eight vermilion, wrinkles are less likely to occur and the followability to the curved shape is enhanced.

上記第１の発明によれば、パッド原料が漏れ出しにくく、且つ皺が生じにくい。
上記第２の発明によれば、形状保持性を高めることが可能である。
上記第３の発明によれば、皺が生じにくく、曲線形状への追従性が高められる。 According to the first aspect of the invention, the pad raw material is unlikely to leak and wrinkles are unlikely to occur.
According to the second aspect, it is possible to improve shape retention.
According to the third aspect of the present invention, wrinkles are less likely to occur, and the ability to follow a curved shape is improved.

以下、図面を参照しながら、本発明の一実施形態について詳細に説明する。本実施形態は、自動車等の車両の室内に装備されるシートのヘッドレスト１０の表皮カバー２０に関する。図１等に示されるように、この表皮カバー２０は袋状であり、パッド１２を内包してヘッドレスト１０を構成する。このヘッドレスト１０の外観は、外形が扁平な洋梨のような形であり、表裏に跨って連続する帯状の色柄模様２２が付されている。ヘッドレスト１０は、底部に設けられた表皮カバー２０の開口部２６から内部に発泡ウレタン等のパッド原料が充填され、該パッド原料を表皮カバー２０の内部で発泡させることにより、表皮カバー２０の内部に一体的にパッド１２が成形されて成る。このヘッドレスト１０の成形方法自体は従来公知の方法から変更を要しない。表皮カバー２０の内面にはフィルム２４が貼付されており、パッド原料の染み出しが防止されている。なお、本実施形態の説明において、表皮カバー２０の「内面」とはヘッドレスト１０を構成した際に内側に向く面のことであり。この「内面」とは反対側のヘッドレスト１０の表面に露出する面を「外面」と称する。以下、表皮カバー２０について、製造方法とともにその構成を説明する。本実施形態の表皮カバー２０は、製織工程、フィルム貼付工程、裁断工程、反転工程を順に経て製造される。   Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The present embodiment relates to a skin cover 20 of a headrest 10 of a seat installed in a vehicle room such as an automobile. As shown in FIG. 1 and the like, the skin cover 20 has a bag shape and includes the pad 12 to constitute the headrest 10. The external appearance of the headrest 10 is a pear-like shape with a flat outer shape, and is provided with a strip-shaped color pattern 22 that is continuous across the front and back. The headrest 10 is filled with a pad raw material such as foamed urethane from the opening 26 of the skin cover 20 provided at the bottom, and the pad raw material is foamed inside the skin cover 20 so that the inside of the skin cover 20 is filled. The pad 12 is integrally formed. The method for forming the headrest 10 itself does not require any change from a conventionally known method. A film 24 is affixed to the inner surface of the skin cover 20 to prevent the pad raw material from seeping out. In the description of the present embodiment, the “inner surface” of the skin cover 20 is a surface facing inward when the headrest 10 is configured. A surface exposed on the surface of the headrest 10 opposite to the “inner surface” is referred to as an “outer surface”. Hereinafter, the structure of the skin cover 20 will be described together with the manufacturing method. The skin cover 20 of this embodiment is manufactured through a weaving process, a film sticking process, a cutting process, and a reversing process in order.

［製織工程］
先ず、表皮カバー２０を構成する生地３０の原反を製織する。図３等に示されるように、生地３０は、袋織により形成されており、大別して二重組織部４０と一重組織部５０とで構成されている。図３〜６では、識別をより容易にするために一重組織部５０に斜線を付して示した。図４に示されるように、二重組織部４０は、ヘッドレスト１０の外形と略同形であり、重なり合う二枚の織物組織４２，４４で構成されている。以下、説明の便宜上、この二枚の織物組織を第１織物組織４２，第２織物組織４４と称する。生地３０において、二重組織部４０を構成する第１織物組織４２と第２織物組織４４とは、ヘッドレスト１０において露出する外面４２ａ，４４ａとなる面が対向した状態で重なり合っている。言い換えれば、生地３０の表裏面には表皮カバー２０の内面４２ｂ，４４ｂとなる面が露出している。第１織物組織４２及び第２織物組織４４は、少なくともヘッドレスト１０の立体形状への追従が容易となる程度に伸縮性を有するのが好ましく、組織形態は特に限定されないが、例えば、伸縮性のあるジャガード織りを採用することができる。また、高捲縮糸により構成することで伸縮性を高めるのも好ましい。この生地３０には、第１織物組織４２と第２織物組織４４のそれぞれの対応位置において外面４２ａ，４４ａから帯状の模様として視認可能な色柄模様２２が織り込まれている。 [Weaving process]
First, the raw fabric of the fabric 30 constituting the skin cover 20 is woven. As shown in FIG. 3 and the like, the fabric 30 is formed by bag weaving, and is roughly composed of a double tissue portion 40 and a single tissue portion 50. In FIGS. 3 to 6, the single tissue portion 50 is indicated by hatching for easier identification. As shown in FIG. 4, the double tissue part 40 has substantially the same shape as the outer shape of the headrest 10, and is composed of two overlapping fabric structures 42 and 44. Hereinafter, for convenience of explanation, these two fabric structures are referred to as a first fabric structure 42 and a second fabric structure 44. In the fabric 30, the first woven fabric structure 42 and the second woven fabric structure 44 constituting the double tissue portion 40 are overlapped with the surfaces to be the outer surfaces 42 a and 44 a exposed in the headrest 10 facing each other. In other words, on the front and back surfaces of the fabric 30, the surfaces serving as the inner surfaces 42 b and 44 b of the skin cover 20 are exposed. It is preferable that the first woven fabric 42 and the second woven fabric 44 have elasticity to such an extent that at least tracking of the three-dimensional shape of the headrest 10 is facilitated, and the tissue form is not particularly limited. Jacquard weave can be used. Moreover, it is also preferable to improve stretchability by using high crimped yarns. The fabric 30 is woven with a color pattern 22 that is visible as a band-like pattern from the outer surfaces 42 a and 44 a at the corresponding positions of the first and second fabric structures 42 and 44.

生地３０において、二重組織部４０は一重組織部５０で囲まれている。一重組織部５０は、二重組織部４０の第１織物組織４２と第２織物組織４４とのそれぞれを構成するタテ糸及びヨコ糸が相互に織り込まれて一枚の織物組織として収束されて成る。したがって、第１織物組織４２と第２織物組織４４とは、その周囲が一重組織部５０によって連結されている。かかる構成により、生地３０は、一重組織部５０を裁断すれば、その裁断面は第１織物組織４２と第２織物組織４４とが閉じ合わされた連結状態となり、二重組織部４０を裁断すれば、その裁断面は第１織物組織４２と第２織物組織４４とがそれぞれ分離した状態となる。図３には裁断線が一点鎖線で示される。本実施形態においては、後述する裁断工程において、表皮カバー２０の外形の周囲に沿って一重組織部５０が裁断され第１織物組織４２と第２織物組織４４の端部が連結状態とされるとともに、パッド原料が注入される開口部２６に対応する位置のみ二重組織部４０が裁断され、開口部２６を有する袋状とされる。   In the dough 30, the double tissue part 40 is surrounded by a single tissue part 50. The single tissue portion 50 is formed by converging the warp yarns and the weft yarns constituting the first fabric structure 42 and the second fabric tissue 44 of the double tissue portion 40 and converging them as a single fabric structure. . Therefore, the periphery of the first fabric structure 42 and the second fabric structure 44 is connected by the single tissue portion 50. With such a configuration, if the dough 30 cuts the single tissue portion 50, the cut surface becomes a connected state in which the first woven fabric structure 42 and the second woven fabric structure 44 are closed, and if the double tissue portion 40 is cut. In the cut surface, the first fabric structure 42 and the second fabric structure 44 are separated from each other. In FIG. 3, the cutting line is indicated by a one-dot chain line. In the present embodiment, in the cutting process described later, the single tissue portion 50 is cut along the periphery of the outer shape of the skin cover 20, and the end portions of the first fabric tissue 42 and the second fabric tissue 44 are connected. The double tissue portion 40 is cut only at a position corresponding to the opening 26 into which the pad raw material is injected to form a bag having the opening 26.

第１織物組織４２と第２織物組織４４とが連結状態とされる二重組織部４０の周囲の一重組織部５０は、二重組織部４０に隣接する境界部位５２が８枚朱子組織（図７参照）で構成されており、該境界部位５２の周囲が平組織５４（図８参照）で構成されている。図３に示されるように、一重組織部５０の他の部分５８は、限定されないが、例えば、朱子組織で構成される。本実施形態において、境界部位５２の８枚朱子組織の幅５２ｗは、好ましくは３〜１０ｍｍであり、より好ましくは５ｍｍである。その周囲の平組織５４の幅５４ｗは、好ましくは５〜１５ｍｍであり、より好ましくは１０ｍｍである。なお、朱子組織とは、タテ糸とヨコ糸の交差点を一定間隔にし、交差点を隣接させずに形成することでタテ糸又はヨコ糸の浮きを多くした組織のことである。図７に例示されるように、８枚朱子組織５２は、タテ糸とヨコ糸とが各８本で完全組織を形成する朱子組織であって、一方の面に表れるタテ糸とヨコ糸の比率が７対１である織物組織である。図８に示される平組織５４は、タテ糸とヨコ糸が一本ずつ交互に交差している織物組織である。   The single tissue part 50 around the double tissue part 40 in which the first textile structure 42 and the second textile structure 44 are connected to each other has eight boundary parts 52 adjacent to the double tissue part 40. 7), and the periphery of the boundary portion 52 is constituted by a flat tissue 54 (see FIG. 8). As FIG. 3 shows, although the other part 58 of the single tissue part 50 is not limited, For example, it is comprised with a satin structure. In the present embodiment, the width 52w of the eight satin structures at the boundary portion 52 is preferably 3 to 10 mm, and more preferably 5 mm. The width 54w of the surrounding flat tissue 54 is preferably 5 to 15 mm, and more preferably 10 mm. Note that the satin structure is a structure in which the warp yarns and the weft yarns are floated by forming the intersections between the warp yarns and the weft yarns at a constant interval and without forming the intersections adjacent to each other. As illustrated in FIG. 7, the eight-leaf satin structure 52 is a satin structure in which the warp yarn and the weft yarn each form a complete structure, and the ratio of the warp yarn to the weft yarn that appears on one surface Is a 7: 1 fabric structure. The flat structure 54 shown in FIG. 8 is a woven structure in which warp yarns and weft yarns alternately intersect one by one.

［フィルム貼付工程］
次に、上記製織工程で形成された生地３０の表裏にフィルム２４を貼付する。フィルム２４は、必ずしも生地３０全体に貼付する必要はなく、少なくとも二重組織部４０と二重組織部４０の周囲の境界部位５２及び平組織５４とがフィルム２４で被覆される。これにより、二重組織部４０は、第１織物組織４２の内面４２ｂ及び第２織物組織４４の内面４４ｂのそれぞれがフィルム２４で被覆される。フィルム２４は、表皮カバー２０の変形に追従可能な程度に柔軟性を有するものが好ましく、例えば、厚さ約３０μｍのポリ塩化ビニル製フィルムを用いることができる。フィルム２４の貼付方法は特に限定されず、例えば、接着剤を用いて接着してもよいし、加熱しながら加圧して融着させてもよい。 [Film pasting process]
Next, the film 24 is stuck on the front and back of the fabric 30 formed in the weaving process. The film 24 is not necessarily applied to the entire fabric 30, and at least the double tissue part 40, the boundary region 52 around the double tissue part 40, and the flat tissue 54 are covered with the film 24. Thereby, in the double tissue part 40, each of the inner surface 42b of the first fabric structure 42 and the inner surface 44b of the second fabric structure 44 is covered with the film 24. The film 24 is preferably flexible so that it can follow the deformation of the skin cover 20, and for example, a polyvinyl chloride film having a thickness of about 30 μm can be used. The method for attaching the film 24 is not particularly limited. For example, the film 24 may be bonded using an adhesive, or may be fused by applying pressure while heating.

［裁断工程］
次に、上記フィルム貼付工程で表裏にフィルム２４の貼付された生地３０を裁断する。図３に示されるように、表皮カバー２０の二重組織部４０の第１織物組織４２と第２織物組織４４とが連結状態とされる周囲では、平組織５４の幅の中間を裁断する。それにより、二重組織部４０は、その周囲が二重組織部４０の輪郭に沿って一定の幅で形成された８枚朱子組織（境界部位）５２で縁取られ、更に該８枚朱子組織５２の周囲が一定幅の平組織５４で取り囲まれた状態となる。裁断により確保される５４の幅５４ｃは、少なくとも５ｍｍ以上とするのが好ましい。図５に示されるように、裁断に際して、輪郭が急な曲線形状である箇所において、平組織５４にスリット５６を形成するのが好ましい。スリット５６は、図５において実線で示される裁断線に略直交して、８枚朱子組織（境界部位）５２には到達させずに平組織５４の範囲内に形成され、図示されるように三角に切り欠かれ、或いは切り込みとして形成される。パッド原料が注入される開口部２６に対応する位置のみは、二重組織部４０の輪郭に沿って二重組織部４０を裁断する。これにより、図６に示されるように、袋状の表皮カバー２０が生地３０から切り取られる。なお、ここで切り取られた表皮カバー２０は、二重組織部４０の第１織物組織４２と第２織物組織４４との外面４２ａ，４４ａが対向した状態である。 [Cutting process]
Next, the fabric 30 with the film 24 attached to the front and back in the film attaching step is cut. As shown in FIG. 3, the middle of the width of the flat tissue 54 is cut around the periphery where the first fabric structure 42 and the second fabric structure 44 of the double tissue portion 40 of the skin cover 20 are connected. As a result, the double tissue portion 40 is bordered by an eight-sheet satin tissue (boundary portion) 52 that is formed with a constant width along the outline of the double-structure portion 40, and further, the eight-sheet satin tissue 52. Is surrounded by a flat tissue 54 having a constant width. The width 54c of the 54 secured by cutting is preferably at least 5 mm. As shown in FIG. 5, it is preferable to form a slit 56 in the flat tissue 54 at a portion where the contour has a sharp curved shape when cutting. The slit 56 is formed in the range of the flat structure 54 without reaching the eight satin structures (boundary portions) 52 substantially orthogonal to the cutting line indicated by the solid line in FIG. Or is formed as a cut. Only the position corresponding to the opening 26 into which the pad raw material is injected cuts the double tissue part 40 along the outline of the double tissue part 40. Thereby, as shown in FIG. 6, the bag-shaped skin cover 20 is cut off from the fabric 30. In addition, the skin cover 20 cut out here is in a state in which the outer surfaces 42a and 44a of the first fabric structure 42 and the second fabric structure 44 of the double tissue portion 40 face each other.

［反転工程］
次に、第１織物組織４２の外面４２ａと第２織物組織４４の外面４４ａとが露出するように、図６に示される上記裁断工程で裁断された表皮カバー２０を反転させる。これにより、図１に示されるように、フィルム２４が表皮カバー２０の内部に面して配置され、一重組織部５０は表皮カバー２０の内側に配置される。以上の工程を経て、本実施形態の表皮カバー２０が製造される。その後、この表皮カバー２０にパッド原料を充填し、内部でパッド原料を発泡させてパッド１２を一体的に成形することにより、ヘッドレスト１０を製造することができる。 [Inversion process]
Next, the skin cover 20 cut in the cutting step shown in FIG. 6 is reversed so that the outer surface 42a of the first woven fabric structure 42 and the outer surface 44a of the second woven fabric structure 44 are exposed. Thereby, as shown in FIG. 1, the film 24 is disposed facing the inside of the skin cover 20, and the single tissue portion 50 is disposed inside the skin cover 20. The skin cover 20 of this embodiment is manufactured through the above steps. Then, the headrest 10 can be manufactured by filling the skin cover 20 with a pad raw material and foaming the pad raw material inside to form the pad 12 integrally.

以上の構成の表皮カバー２０によれば以下の作用効果を奏する。
表皮カバー２０は袋織により袋状に形成されており、二重組織部４０を構成する第１織物組織４２と第２織物組織４４とは、それぞれの構成繊維を織り込んで一枚の織物組織とされた一重組織部５０により連結されている。そのため、第１織物組織４２と第２織物組織４４との間に隙間が生じにくく、パッド原料が漏れ出しにくい。そして、一重組織部５０の二重組織部４０に隣接する境界部位５２が柔軟で方向性がなく融通性に富む８枚朱子組織で構成されているため、パッド原料の発泡による圧力で生じる第１織物組織４２と第２織物組織４４とを裂く作用力を緩衝し、第１織物組織４２と第２織物組織４４との境界に皺を生じさせにくい。また、８枚朱子組織（境界部位）５２の周囲は、丈夫な平組織５４で構成されており、裁断面がほつれにくく、境界部位５２が裂けるのを防ぐことができる。したがって、平組織５４は、裁断にあたりオーバーロック縫い等のほつれ防止のための特別な手段を要しない。従来のオーバーロック縫いされた表皮カバーでは、裁断線に直交するスリットの形成は縫糸を切断するため、実質的に困難であった。しかし、本実施形態の表皮カバー２０では適宜スリット５６を形成することができ、表皮カバー２０の曲線形状への追従性を高めることが可能である。また、袋織により形成された第１織物組織４２と第２織物組織４４とは、その相対位置がずれることがなく、ヘッドレスト１０の表裏に連続して第１織物組織４２と第２織物組織４４とに跨る模様２２が相互にずれない。 According to the skin cover 20 having the above configuration, the following operational effects can be obtained.
The skin cover 20 is formed in a bag shape by bag weaving, and the first woven fabric structure 42 and the second woven fabric structure 44 constituting the double tissue portion 40 are made into a single woven fabric structure by weaving the respective constituent fibers. Are connected by a single tissue portion 50. Therefore, a gap is hardly generated between the first woven fabric structure 42 and the second woven fabric structure 44, and the pad raw material is hardly leaked. And since the boundary part 52 adjacent to the double structure | tissue part 40 of the single structure | tissue part 50 is comprised with the 8 satin structure | tissue which is flexible, has no directionality, and is flexible, the 1st produced by the pressure by foaming of a pad raw material The acting force that tears the fabric structure 42 and the second fabric structure 44 is buffered, and it is difficult to cause wrinkles at the boundary between the first fabric structure 42 and the second fabric structure 44. Further, the periphery of the eight-leaf satin structure (boundary part) 52 is constituted by a strong flat structure 54, and the cut surface is not easily frayed, and the boundary part 52 can be prevented from being torn. Therefore, the flat structure 54 does not require any special means for preventing fraying such as overlock stitching when cutting. In the conventional overlock-stitched skin cover, it is substantially difficult to form a slit perpendicular to the cutting line because it cuts the sewing thread. However, in the skin cover 20 of the present embodiment, the slits 56 can be appropriately formed, and the followability to the curved shape of the skin cover 20 can be improved.
