Description

【０００１】
【発明の属する技術分野】
本発明は、着座面からカマチ部にわたるコーナ部に適度に膨出した状態を保たせることができるうえに、縫製作業も容易で安価に提供できる車両用シートカバーに関するものである。
【０００２】
【従来の技術】
従来から、車両用シートカバーとして、例えば、実開昭６１−１９４３５５号公報や実開平５−４２７９７号公報などに見られるように、着座面を覆う表面被覆部と側面を覆うカマチ被覆部とを縫着一体化した袋状カバーが広く用いられている。
【０００３】
ところが、従来のこの種の車両用シートカバーにおいては、いずれも単にクッション体に密着して被覆するのみで、特に、着座面からカマチ部にわたるコーナ部に立体感を得ることはできないものであった。また、コーナ部における立体感を得るために、コーナ部に保形芯材を予めセットしておいたり、後工程によりコーナ部を縫製加工する等の特別な細工を施したものも一部に見られるが、このような細工を施したものは、縫製作業性に劣るとともに装着作業性にも劣り、更に生産コストも高くなるという問題点があった。
【０００４】
【発明が解決しようとする課題】
本発明は前記のような従来の問題点を解決して、コーナ部の表面が適度に膨出して風合いのある優れた立体感を呈することができるとともに、優れた縫製作業性および装着作業性も発揮することができ、また、生産コストの低廉化も図ることができる車両用シートカバーを提供することを目的として完成されたものである。
【０００５】
【課題を解決するための手段】
前記のような課題を解決するためになされた本発明の車両用シートカバーは、シートカバー本体が、シートの着座面を覆う座面被覆部とカマチ被覆部との間にシートのコーナ部を覆うパッド層付きの幅狭のコーナ被覆部を介在させて三者を縫着一体化した袋状カバーであって、シートカバー本体の裏側には長さがコーナ被覆部の幅より短く、その両端縁を表面被覆部とコーナ被覆部との縫合部と、該コーナ被覆部とカマチ被覆部との縫合部に縫着してあり、前記コーナ被覆部を幅方向に彎曲させて外向きに膨出させる牽引用の力布が設けられていることを特徴とするものである。
【０００６】
【発明の実施の形態】
以下に、図面を参照しつつ本発明の好ましい実施の形態を示す。
図面は自動車用シートバックに適用した例を示すものであって、図中１はファブリック地よりなるシートカバー本体であって、このシートカバー本体１は、着座面を覆う表面被覆部１ａと、この表面被覆部１ａの端部に続くコーナ部を覆う幅狭のコーナ被覆部１ｂと、側面を覆うカマチ被覆部１ｃとよりなるもので、これら表面被覆部１ａとコーナ被覆部１ｂとカマチ被覆部１ｃとは各々縫合部３ａ、３ｂにより縫着されたものとなっている。
【０００７】
前記したコーナ被覆部１ｂは、ポリウレタンフォーム等のクッション性のあるパッド層２が裏面にラミネートされたもので、前記コーナ被覆部１ｂとカマチ被覆部１ｃとの縫合部３ｂは力布４により内側すなわち表面被覆部側へ引っ張られた状態とされ、シートカバー本体１の裏側に設けられている力布４による牽引で前記コーナ被覆部が裏面のパッド層２の反発力下に幅方向に彎曲させて外向きに膨出されている。なお、図１に示したものにおいては、表面被覆部１ａおよびカマチ被覆部１ｃにも同様のパッド層を有するものとしてあるが、少なくともコーナ被覆部１ｂ以外のパッド層は必要に応じ設けるものである。
【０００８】
前記縫合部３ｂを力布４により内側へ牽引する手段としては、図１に示すように、コーナ被覆部１ｂの幅よりも短い力布４を用いてその一端縁を縫合部３ｂに縫着するとともに他端を表面被覆部１ａとコーナ被覆部１ｂとの縫合部３ａに逢着するのを普通とするが、図２に示すように、一端縁をコーナ被覆部１ｂとカマチ被覆部１ｃとの縫合部３ｂに縫着したものとしておき、前記表面被覆部１ａとコーナ被覆部１ｂとの縫合部３ａをシート側の固定ワイヤ５に吊込材６を介して引き込む吊込用Ｃリング７にこの力布４の他端縁を係止させるようにしてもよい。
【０００９】
次に、図１に示す車両用シートカバーの縫製手順につき説明する。
先ず、各別に裁断して用意された表面被覆部１ａとコーナ被覆部１ｂとカマチ被覆部１ｃのうち、カマチ被覆部１ｃの上端縁と力布４の端縁の表側を重ねて仮縫を施し、次にコーナ被覆部１ｂとカマチ被覆部１ｃとを該カマチ被覆部１ｃの上端縁と力布４の一端縁の表側を重ねて縫合部３ｂにおいて縫着しておく。次いで、コーナ被覆部１ｂの他端縁と力布４の他端縁を重ねて仮縫を施し、このコーナ被覆部１ｂの他端縁を表面被覆部１ａの端縁の表側を重ねて前記と同様に縫合部３ａにおいて縫着し、最後に、力布４の他端縁を内側へ牽引してコーナ被覆部１ｂがパッド層２の反発力により外側に向け膨出した状態とし、この態勢を保持するよう力布４の端縁部を前記した縫合部３ａに逢着してシートカバー本体１とすればよい。このため、本発明のシートカバーの縫製作業は従来のように予め保形芯材をセットしておいたり、後工程によりサイド部を縫製加工する等の特別な細工を必要とすることなく、通常の縫製作業のみで簡単かつ効率的に生産することができることとなる。
【００１０】
このように構成された車両用シートカバーは、コーナ被覆部１ｂとカマチ被覆部１ｃとの縫合部３ｂが力布４により内側へ牽引された状態とされ、該コーナ被覆部１ｂがパッド層２の反発力により外側に向け膨出・隆起されたものとなっているので、コーナ部表面は常に適度に膨出した状態に保持されることとなって優れた立体感を呈することとなり、また、裏側のパッド層２の弾性により風合いおよび十分な柔らかさもあり高品質なものとなる。
【００１１】
【発明の効果】
本発明は以上の説明より明らかなように、コーナ部表面が適度に膨出して風合いのある優れた立体感のあるものとすることができるとともに、優れた縫製作業性および装着作業性を発揮することができ、また、生産コストの低廉化も図ることができるものである。
よって本発明は従来の問題点を一掃した車両用シートカバーとして、産業の発展に寄与するところは極めて大である。

This is a bag-like cover that is formed by sewing and integrating the three parts with a narrow corner covering part with a pad layer, and the length of the back side of the seat cover body is shorter than the width of the corner covering part. Are sewn to a stitched portion between the surface covering portion and the corner covering portion and a stitched portion between the corner covering portion and the kamachi covering portion, and the corner covering portion is bent in the width direction to bulge outward. It is characterized by the fact that a traction fabric is provided.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The drawings show an example applied to an automobile seat back. In the figure, reference numeral 1 denotes a seat cover body made of fabric, and the seat cover body 1 includes a surface covering portion 1a covering a seating surface, It consists of a narrow corner covering portion 1b covering the corner portion following the end portion of the surface covering portion 1a, and a kamachi covering portion 1c covering the side surface, and these surface covering portion 1a, corner covering portion 1b and kamachi covering portion 1c. Are respectively sewn by stitching portions 3a and 3b.
[0007]
The above-described corner covering portion 1b is obtained by laminating a cushioning pad layer 2 such as polyurethane foam on the back surface, and the stitched portion 3b between the corner covering portion 1b and the kamachi covering portion 1c is formed on the inner side by the force cloth 4, that is, The corner covering portion is bent in the width direction under the repulsive force of the back-side pad layer 2 by being pulled by the power cloth 4 provided on the back side of the seat cover body 1. It bulges outward. In the example shown in FIG. 1, the surface covering portion 1a and the keratin covering portion 1c have the same pad layer, but at least pad layers other than the corner covering portion 1b are provided as necessary. .
[0008]
As a means for pulling the stitching portion 3b inward by the force cloth 4, as shown in FIG. 1, one end edge is sewn to the stitching portion 3b using the force cloth 4 shorter than the width of the corner covering portion 1b. At the same time, the other end is usually fastened to the stitched portion 3a of the surface covering portion 1a and the corner covering portion 1b. However, as shown in FIG. 2, the one end edge is stitched between the corner covering portion 1b and the kamachi covering portion 1c. It is assumed that the surface 3a is sewn to the portion 3b, and this force is applied to the suspension C-ring 7 for pulling the stitched portion 3a of the surface covering portion 1a and the corner covering portion 1b into the fixing wire 5 on the seat side via the suspension member 6. The other end edge of the cloth 4 may be locked.
[0009]
Next, the sewing procedure for the vehicle seat cover shown in FIG. 1 will be described.
First, among the surface covering portion 1a, the corner covering portion 1b, and the kamachi covering portion 1c prepared by cutting separately, the upper end edge of the kamachi covering portion 1c and the front side of the end edge of the power cloth 4 are overlapped to perform temporary sewing. Next, the corner covering portion 1b and the keratin covering portion 1c are sewn together at the stitching portion 3b with the upper end edge of the keratin covering portion 1c and the front side of the one end edge of the force cloth 4 overlapped. Next, the other end edge of the corner covering portion 1b and the other end edge of the force cloth 4 are overlapped to perform temporary sewing, and the other end edge of the corner covering portion 1b is overlapped with the front side of the end edge of the surface covering portion 1a. Similarly, sewing is performed at the stitching portion 3a, and finally, the other end edge of the webbing 4 is pulled inward so that the corner covering portion 1b bulges outward due to the repulsive force of the pad layer 2, and this posture is changed. What is necessary is just to attach the edge part of the force cloth 4 to the above-mentioned stitching | suture part 3a so that it may hold | maintain, and to make the seat cover main body 1. FIG. For this reason, the sewing operation of the seat cover of the present invention is usually performed without requiring special work such as setting a shape-retaining core material in advance as in the past or sewing the side portion in a subsequent process. Therefore, it can be produced easily and efficiently only by sewing work.
[0010]
The vehicle seat cover configured as described above is in a state in which the stitched portion 3b of the corner covering portion 1b and the kamachi covering portion 1c is pulled inward by the force cloth 4, and the corner covering portion 1b is formed on the pad layer 2. Because it is bulged and raised outward due to the repulsive force, the corner surface is always kept in a moderately bulged state and exhibits an excellent stereoscopic effect. Due to the elasticity of the pad layer 2, there is a texture and sufficient softness, so that the quality is high.
[0011]
【The invention's effect】
As is apparent from the above description, the present invention can make the surface of the corner portion appropriately bulge and have an excellent three-dimensional feeling with a texture, and exhibits excellent sewing workability and mounting workability. In addition, the production cost can be reduced.
Therefore, the present invention greatly contributes to industrial development as a vehicle seat cover that eliminates the conventional problems.
