Description

【０００１】
【発明の属する技術分野】
この発明は、車両等のシートをカバーリングするシートカバーに係り、詳しくはシートカバーのシートカバーパッドにラミネート接着する裏基布に関する。
【０００２】
【従来の技術】
従来、この種の車両等のシートフレームに取付けたクッションパッドをカバーリングするシートカバー１は例えば図８(a) に示すようにファブリック、塩ビレザー等からなる表皮材２と、この表皮材２に接着されるウレタンフォームスラブからなるカバーパッド３と、このカバーパッド３に接着される不織布からなる裏基布４とから構成されている。
【０００３】
【解決しようとする課題】
しかしながら、この従来のシートカバー構成においては表皮材２およびカバーパッド３は伸縮性を有するファブリック、塩ビレザーおよびウレタンフォームスラブであるのに対し、裏基布４は繊維を糸にしないで集合体とし、繊維相互を接着させて薄い布状に圧縮した不織布であることから、伸縮性に欠けるため外力が作用して表皮材２およびカバーパッド３が湾曲状に弾性変形すると裏基布４はこれに追従できず、このため図８(b) に示すように表皮材２側に折れしわ５が発生して見栄えを悪くする問題があった。
本発明は、上記従来の問題点を解決するためになされたもので、表皮材およびカバーパッドの伸縮に追従することができて表皮材に折れしわの発生を防止することのできるシートカバーパッドの裏基布を提供することを目的とするものである。
【０００４】
【課題を解決するための手段】
本発明は、上記技術課題を解決するため、
シートクッションをカバーリングする表皮材とカバーパッドおよび裏基布を貼着してなるシートカバーにおいて、前記裏基布には細長形状の開縮手段を相互に９０度位相して千鳥状に配設する構成とし、また、前記開縮手段はエンボス、スリット状の溝孔としたことにより、
シートに乗員が着座するとシートカバーの表皮材およびカバーパッドは湾曲状に弾性変位され、これにより、同カバーパッドに貼着した裏基布には着座部を中心とする外周方向に外力が作用すると、この裏基布には細長形状の開縮手段をその長手方向を交互に９０度位相する千鳥状に配設するとともに、カバーパッドに対し接着部と開縮手段部分の被接着部とを有して接着したものであるから、とくに、幅方向での開縮手段の変形・変位が顕著であり、この各開縮手段の総合的な変形・変位により同表皮材およびカバーパッドの弾性変位に追従して開縮することができるので、表皮材側に折れしわの発生することが防止される、の作用効果を奏する。
【０００５】
【実施例】
次に、本発明の実施例を図面にしたがって説明すると、図１はシートカバー１の断面図、図２は裏基布６の平面図、図３は図２にＡ−Ａ線断面図を示すもので、このシートカバー１は従来と同様にファブリック、塩ビレザー等からなる表皮材２と、この表皮材２に接着されるウレタンフォームスラブからなるカバーパッド３と、このカバーパッド３に接着される不織布からなる裏基布６とから構成されている。
【０００６】
この裏基布６である不織布は繊維を糸にしないで集合体とし、繊維相互を接着させて薄い布状に圧縮して成形する圧縮過程で凹凸状のエンボス加工を施したシート状に形成され、この凹凸状のエンボス７（開縮手段ともいう）の形状は図２，図３に示すように長円形状（例えば長手方向ｌ＝２０mm、幅ｗ＝１０mm、深さｔ＝１mm程度）に形成されてエンボス７の背面側には凹部７ａが形成されるとともに、図示のようにこのエンボス７はその長手方向ｌを交互に９０度位相する千鳥状に配設形成されている。
【０００７】
このように形成された裏基布である不織布をカバーパッド３の背面側にラミネート接着すると、図１に示すように接着部８とエンボス７部分には非接着部９が形成される。このように裏基布６を接着したシートカバー１によりクッションパッドをカバーリングした状態で、同シートに乗員が着座すると着座部を中心として図４(b) および図５に示すようにシートカバー１の表皮材２およびカバーパッド３は湾曲状に弾性変位される。このカバーパッド３の弾性変位により、同カバーパッド３に貼着した裏基布６には着座部を中心とする外周方向に外力Ｆが作用する。
【０００８】
このように外力Ｆを受ける裏基布６には長円形状のエンボス７をその長手方向を交互に９０度位相する千鳥状に配設するとともに、カバーパッド３に対し接着部８とエンボス６の被接着部９とを有して接着したものであるから、とくに、幅ｗ方向でのエンボス７の変形・変位が顕著であり、この各エンボス７の総合的な変形・変位により同表皮材２およびカバーパッド３の弾性変位に追従して開縮することができるので、表皮材２側に折れしわ５の発生することが防止される。
【０００９】
また、図６および図７(a)(b)は不織布に形成する開縮手段の他の態様を示すもので、裏基布１０は上記エンボス７に代りスリット状の溝孔１１を設ける構成としたもので、このスリット状の溝孔１１は長さｌ＝２０mm、幅ｗ＝１mm程度に形成されて、上記と同様に図示のように長さ方向を交互に９０度位相されて千鳥状に配設されている。このように形成された裏基布１０をカバーパッド３に貼着することで接着部８とスリット状の溝孔１１部分では被接着部９となり、これにより上記と同様にこのスリット状の溝孔１１は表皮材２およびカバーパッド３の弾性変位に追従して表皮材２側に折れしわ５の発生を防止することができる。
【００１０】
なお、上記実施例においては、長円形状のエンボス７、スリット状の溝孔１１の開縮手段を例示したが、これに限定するものではなく、細長形状のエンボスあるいは孔、例えば楕円形状、菱形形状等で相互に９０度位相して千鳥状に配設してｘ，ｙ方向に相互に開縮可能な形状の開縮手段であればよい。
【００１１】
【発明の効果】
本発明は、上記のようにシートに乗員が着座するとシートカバーの表皮材およびカバーパッドは湾曲状に弾性変位され、これにより、同カバーパッドに貼着した裏基布には着座部を中心とする外周方向に外力が作用すると、この裏基布には細長形状の開縮手段をその長手方向を交互に９０度位相する千鳥状に配設するとともに、カバーパッドに対し接着部と開縮手段部分の被接着部とを有して接着したものであるから、とくに、幅方向での開縮手段の変形・変位が顕著であり、この各開縮手段の総合的な変形・変位により同表皮材およびカバーパッドの弾性変位に追従して開縮することができるので、表皮材側に折れしわの発生することが防止される。

BACKGROUND OF THE INVENTION
The present invention relates to a seat cover for covering a seat of a vehicle or the like, and more particularly to a back base fabric that is laminated and bonded to a seat cover pad of a seat cover.
[0002]
[Prior art]
Conventionally, a seat cover 1 for covering a cushion pad attached to a seat frame of this type of vehicle or the like includes, for example, a skin material 2 made of fabric, PVC leather, etc., as shown in FIG. The cover pad 3 is made of a urethane foam slab to be bonded, and the back base cloth 4 is made of a nonwoven fabric bonded to the cover pad 3.
[0003]
[Problems to be solved]
However, in this conventional seat cover configuration, the skin material 2 and the cover pad 3 are elastic fabric, PVC leather, and urethane foam slab, whereas the back base fabric 4 is an aggregate without using fibers as threads. Since the non-woven fabric is compressed into a thin cloth by bonding the fibers together, the back base fabric 4 will be in contact with the outer skin material 2 and the cover pad 3 elastically deformed due to external force due to lack of stretchability. Accordingly, there was a problem that the crease 5 was generated on the skin material 2 side as shown in FIG.
The present invention has been made to solve the above-described conventional problems, and is a seat cover pad that can follow the expansion and contraction of the skin material and the cover pad and can prevent the folding of the skin material. The purpose is to provide a backing fabric.
[0004]
[Means for Solving the Problems]
In order to solve the above technical problem, the present invention
In the seat cover formed by sticking the cover material covering the seat cushion, the cover pad, and the back base fabric, the back base fabric is arranged in a staggered manner with elongated strips 90 degrees out of phase with each other. In addition, the opening and contracting means is an embossed, slit-shaped groove,
When an occupant sits on the seat, the skin material and the cover pad of the seat cover are elastically displaced in a curved shape, so that an external force acts on the back base fabric adhered to the cover pad in the outer circumferential direction centered on the seating portion. The back base fabric is provided with elongated stripping means arranged in a zigzag pattern with the longitudinal direction alternately 90 degrees, and has an adhesive portion and an adherend portion of the shrinking means portion with respect to the cover pad. In particular, the deformation / displacement of the expanding / contracting means in the width direction is remarkable, and the overall deformation / displacement of each expanding / contracting means reduces the elastic displacement of the skin material and cover pad. Since it can follow and open and contract, it is possible to prevent the occurrence of creases and wrinkles on the skin material side.
[0005]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of the seat cover 1, FIG. 2 is a plan view of the back base cloth 6, and FIG. The seat cover 1 is bonded to the cover pad 3 made of a urethane foam slab bonded to the cover material 2 and the cover material 3 made of fabric, PVC leather, etc., as in the prior art. It is comprised from the back base fabric 6 which consists of a nonwoven fabric.
[0006]
This non-woven fabric, which is the backing base fabric 6, is formed into a sheet-like shape that has been embossed in a concavo-convex shape during the compression process in which the fibers are aggregated without forming yarns, and the fibers are bonded together and compressed into a thin cloth shape. As shown in FIGS. 2 and 3, the shape of the uneven emboss 7 (also referred to as an opening / closing means) is an oval shape (for example, the longitudinal direction l = 20 mm, the width w = 10 mm, and the depth t = 1 mm). A recess 7a is formed on the back side of the emboss 7 so that the emboss 7 is formed in a zigzag pattern in which the longitudinal directions 1 are alternately phased by 90 degrees as shown in the figure.
[0007]
When the non-woven fabric, which is the back base fabric formed in this way, is laminated and bonded to the back side of the cover pad 3, a non-bonded portion 9 is formed at the bonded portion 8 and the embossed portion 7 as shown in FIG. When the occupant sits on the seat in the state where the cushion pad is covered with the seat cover 1 to which the back base fabric 6 is bonded in this way, the seat cover 1 as shown in FIG. 4 (b) and FIG. The skin material 2 and the cover pad 3 are elastically displaced in a curved shape. Due to the elastic displacement of the cover pad 3, an external force F acts on the back base fabric 6 adhered to the cover pad 3 in the outer peripheral direction centering on the seating portion.
[0008]
In this way, the back base fabric 6 that receives the external force F is provided with the oval embosses 7 in a staggered manner in which the longitudinal directions are alternately shifted by 90 degrees, and the adhesive portion 8 and the emboss 6 are formed on the cover pad 3. In particular, since the emboss 7 is deformed / displaced in the width w direction, the skin material 2 is formed by the total deformation / displacement of each emboss 7. Since the cover pad 3 can be opened and contracted following the elastic displacement of the cover pad 3, it is possible to prevent the crease 5 from occurring on the skin material 2 side.
[0009]
FIGS. 6 and 7 (a) and 7 (b) show another embodiment of the cleaving means formed on the nonwoven fabric, and the back base fabric 10 has a configuration in which slit-like grooves 11 are provided in place of the embosses 7. This slit-shaped groove 11 is formed with a length l = 20 mm and a width w = 1 mm, and in the same manner as described above, the length directions are alternately phased 90 degrees as shown in a staggered pattern. It is arranged. By sticking the back base fabric 10 formed in this way to the cover pad 3, the bonded portion 8 and the slit-shaped groove 11 portion become the bonded portion 9, and thus the slit-shaped groove hole as described above. 11 can follow the elastic displacement of the skin material 2 and the cover pad 3 to prevent the generation of wrinkles 5 on the skin material 2 side.
[0010]
In the above embodiment, the oval-shaped emboss 7 and the slit-like slot 11 opening / shrinking means are exemplified, but the present invention is not limited to this, and an elongated emboss or hole such as an oval shape or a rhombus is used. Any cresting means may be used as long as it is arranged in a zigzag pattern 90 degrees out of phase with each other in a shape or the like and can be cleaved in the x and y directions.
[0011]
【The invention's effect】
In the present invention, when an occupant sits on a seat as described above, the skin material and the cover pad of the seat cover are elastically displaced in a curved shape, so that the back base fabric adhered to the cover pad is centered on the seating portion. When an external force is applied in the outer peripheral direction, elongated back and forth means are arranged on the back base fabric in a zigzag pattern with the longitudinal direction alternately 90 degrees, and the adhesive portion and the opening and closing means are attached to the cover pad. In particular, the deformation / displacement of the expanding / contracting means in the width direction is remarkable. Since it can be opened and contracted following the elastic displacement of the material and the cover pad, the occurrence of creases and wrinkles on the skin material side is prevented.
