従来クッション体のクッション面は、その上に体重をあづけたとき、柔らかく弾力性があって心地よさが感じられるようにするため、ウレタンフォームや繊維積層硬綿等を下敷材とし、その上に布帛や皮革等の表地を積層して構成されている。しかし、ウレタンフォームや繊維積層硬綿等の下敷材は重厚で嵩張り、取扱い難いことからして、近時は、向き合ってクッション体のフレームの一部を構成している支桿と支桿の間に布帛を架け渡してクッション面を構成する試みがなされている。   The cushion surface of the conventional cushion body is made of urethane foam or fiber-laminated hard cotton as an underlaying material so that when the weight is applied on it, it is soft, elastic and comfortable. It is constructed by laminating outer fabrics such as fabric and leather. However, underlay materials such as urethane foam and fiber-laminated hard cotton are heavy and bulky, and are difficult to handle. Recently, the support and support that form part of the frame of the cushion body face each other. Attempts have been made to construct a cushion surface by placing a fabric between them.

クッション面に要求される弾力性は、その部位によって異なり、特に、自動車、列車、航空機、船舶等の交通機関の座席のように大型のクッション体では、その腰掛け部には体重の多くが掛かるので伸び難い強い弾力性が要求され、背凭れ部には掛かる体重が比較的少ない弱く伸び易い弾力性が要求され、脚載せ部には掛かる体重が最も少ないので更に弱く伸び易い弾力性が要求される。そして、クッション体の同じ腰掛け部の部内でも、その臀部の当接する部分（臀部）には伸び難い強い弾力性が要求され、その大腿部の当接する部分（大腿部）には弱く伸び易い弾力性が要求される。   The elasticity required for the cushion surface varies depending on the part, and in particular, a large cushion body such as a seat of a transportation system such as an automobile, a train, an aircraft, a ship, etc., takes a lot of weight on the seat. Strong elasticity that is difficult to stretch is required, the weight applied to the backrest is relatively low, and elasticity that is easy to stretch is required, and the weight that is applied to the leg rest is the least so that it is required to be even weaker and easier to stretch . And even within the same seat portion of the cushion body, the portion (buttock) where the buttocks abuts is required to have strong elasticity that is difficult to extend, and the portion where the thigh abuts (thigh) is weak and easily stretched. Elasticity is required.

下敷材に従来使用されている嵩高で重厚なウレタンフォームや繊維積層では、それに掛かる体重に応じて局部的に窪み、身体に作用するクッション面から反力が平均化される。それに対し、布帛に成るクッション面では、何れの部位に体重が掛かっても、その体重はテンションとなって布帛全体に均等に伝わり、体重が掛かる部位だけが局部的に窪むことがなく、全体が同じ伸び率をもって沈み、伸び易い布帛では全体がすり鉢状に窪み、その窪に身体が嵌まり込む恰好になり、そのすり鉢状窪の周縁から側圧を受けて窮屈に感じられ、伸び難い布帛では、布帛からの反力が、その体重の掛かる部位から集中して作用するので、痛く感じられ、長時間体重をあづけるに耐え難くなる。   In the bulky and heavy urethane foam and fiber laminate conventionally used for the underlay material, the reaction force is averaged from the cushion surface acting on the body, which is recessed locally according to the weight applied to it. On the other hand, in the cushion surface made of the fabric, no matter where the weight is applied, the weight is transmitted to the entire fabric as tension, and only the portion where the weight is applied is not locally recessed, In the fabric that sinks with the same elongation rate and is easy to stretch, the whole becomes a mortar-like depression, and the body fits into the depression, and it feels cramped by receiving side pressure from the periphery of the mortar-like depression, Since the reaction force from the fabric concentrates and acts from the part where the weight is applied, it feels painful and it becomes difficult to endure the weight for a long time.

そこで本発明は、フレームの支桿と支桿の間にクッション布帛を架け渡して構成されるクッション面に掛かる体重が各部位に異なるとしても、各部位に同じ程度の窪みが出来、クッション布帛から身体に均等に分散して反力が作用し、身体にフィットしたクッション体を得ることを目的とする。本発明の他の目的は、そのようにクッション布帛の伸縮弾性が部位によって異なるようにするとしても、その伸縮弾性の差異が外観の差異となってクッション面に現れず、美的統一がとれてインテリアとしての商品価値が高く、座り心地のよいクッション体を得ることである。   Therefore, even if the weight applied to the cushion surface formed by suspending the cushion fabric between the supports of the frame is different in each part, the present invention can make the same degree of depression in each part, and The purpose is to obtain a cushion body that is evenly distributed over the body and a reaction force acts on and fits the body. Another object of the present invention is that even if the elastic elasticity of the cushion fabric is different depending on the part, the difference in elastic elasticity does not appear on the cushion surface as a difference in appearance, and the interior is aesthetically unified. It is to obtain a cushion body that has a high commercial value and is comfortable to sit on.

本発明者は、上記目的をもって、腰を下ろしたとき、どの部位が硬ければ痛みを感じさせることになるのかを調べるために、太い弾性糸条の軸芯を一定方向に揃えて構成され、伸び難いクッション布帛１３を、フレーム１１に 支持されて向き合う左右の支桿１２・１２の間に、その弾性糸条の軸芯方向を左右の支桿１２・１２が向き合う幅方向Ｇに向け、その幅方向Ｇに直交する奥行き方向Ｈにおける前後両端縁１８・１９をフリーにし、充分に緊張させて張設して成るクッション体２０のクッション面２１に補強布片２２を、そのクッション面の部位と補強布片２２のサイズと数を変えて縫合一体化し（図３）、その縫合部位と補強布片２２のサイズを変える度に、その補強布片２２の縫合されたクッション面２１に腰を降ろして座り心地を確かめたところ、左右の支桿１２と支桿１２の間の中間部（１５）に奥行き方向Ｈへと続く補強布片２２、特に、奥行き方向Ｈにおける中心部１７から後端縁１８まで続く補強布片２２をクッション布帛２０に縫合するとき（図４）、その補強布片２２が硬く感じられることがなく、座り心地がよく、長時間着座して疲労感を与えないとの知見を得て本発明を完成するに到った。尚、本発明の完成に到る過程での実験において、キルティングのように重ね合わせた補強布片２２とクッション布帛１３に細かくミシンを当て、貼り合わせるかのようにそれらを強固に縫合一体化している。   The present inventor has the above-mentioned purpose, and in order to examine which part is hard to feel pain when sitting down, the shaft core of the thick elastic yarn is arranged in a certain direction, The cushion fabric 13 which is not easily stretched is supported between the left and right supports 12 and 12 which are supported by the frame 11, and the axial center direction of the elastic yarn is directed in the width direction G where the left and right supports 12 and 12 face each other. The reinforcing cloth piece 22 is attached to the cushion surface 21 of the cushion body 20 formed by stretching the tension body 18 and 19 in the depth direction H perpendicular to the width direction G in a free and fully tensioned state. The size and the number of the reinforcing cloth pieces 22 are changed and integrated by stitching (FIG. 3), and the waist is lowered to the stitched cushion surface 21 of the reinforcing cloth pieces 22 every time the stitched portion and the size of the reinforcing cloth pieces 22 are changed. Sitting As a result, the reinforcing cloth piece 22 extending in the depth direction H in the intermediate portion (15) between the left and right support rods 12 and the support rod 12, particularly, from the center portion 17 in the depth direction H to the rear end edge 18 is continued. When the reinforcing cloth piece 22 is stitched to the cushion cloth 20 (FIG. 4), the reinforcing cloth piece 22 is not felt hard, has a good sitting comfort, and has a knowledge that it does not give a feeling of fatigue by sitting for a long time. The present invention has been completed. In an experiment in the process of completing the present invention, a sewing machine is finely applied to the reinforcing fabric piece 22 and the cushion fabric 13 that are overlapped as in quilting, and they are firmly stitched together as if they are bonded together. Yes.

本発明に係るクッション布帛は、クッション体のフレーム１１に向かい合わせに固定された支桿１２と支桿１２の間に直接または治具を介して張設して使用される弾性糸条の織編込まれているクッション布帛１３において、そのクッション布帛１３の縦横の何れか一方を幅方向（Ｇ）とし、その他方を奥行き方向（Ｈ）とするとき、（ａ） 奥行き方向（Ｈ）の伸び率１０％に伸長時の伸長応力( Ｆｇ）が、幅方向（Ｇ）における位置によって異なり、（ｂ） 幅方向（Ｇ）の中間部１５の奥行き方向（Ｈ）の伸び率１０％に伸長時の伸長応力( Ｆｃ）が、その中間部１５の左右に続く幅方向（Ｇ）の側部１６の奥行き方向（Ｈ）の伸び率１０％に伸長時の伸長応力( Ｆｓ）よりも大きく、（ｃ） その中間部１５の伸長応力( Ｆｃ）が大となる低伸縮部（中間部１５）が、奥行き方向（Ｈ）における中心部１７から後端縁１８に至るまで連続していることを第１の特徴とする。   The cushion fabric according to the present invention is a woven or knitted elastic yarn that is used directly or via a jig between a support 12 fixed to the frame 11 of the cushion body and facing the support 12. In the cushion fabric 13 that is embedded, when either the longitudinal or lateral direction of the cushion fabric 13 is the width direction (G) and the other is the depth direction (H), (a) the elongation in the depth direction (H) The elongation stress (Fg) when stretched to 10% varies depending on the position in the width direction (G), and (b) the elongation ratio in the depth direction (H) of the intermediate portion 15 in the width direction (G) is 10% when stretched. The elongation stress (Fc) is larger than the elongation stress (Fs) at the time of elongation to 10% elongation in the depth direction (H) of the side portion 16 in the width direction (G) following the right and left of the intermediate portion 15; ) The elongation stress (Fc) of the intermediate portion 15 becomes large Stretchable portion (intermediate portion 15), the first characterized in that continuously from the central portion 17 in the depth direction (H) up to the rear edge 18.

This is the point (h ≧ g).

本発明に係るクッション布帛の第３の特徴は、上記第１および第２の何れかの特徴に加えて、（ｅ） 幅方向（Ｇ）における伸び率１０％に伸長時の伸長応力Ｆｗが５０Ｎ／５ｃｍ以上であり、（ｆ） 幅方向（Ｇ）の中間部１５の奥行き方向（Ｈ）の伸び率１０％に伸長時の伸長応力( Ｆｃ）が、その中間部１５の左右に続く幅方向（Ｇ）の側部１６の奥行き方向（Ｈ）の伸び率１０％に伸長時の伸長応力( Ｆｓ）の１．１倍以上である点にある。   A third feature of the cushion fabric according to the present invention is that, in addition to any one of the first and second features, (e) the elongation stress Fw during elongation is 50 N at an elongation rate of 10% in the width direction (G). / 5 cm or more, and (f) the width direction (G) in the width direction (G) is 10% in the depth direction (H), and the elongation stress (Fc) at the time of elongation continues to the left and right of the middle portion 15 (G) It is in the point which is 1.1 times or more of the elongation stress (Fs) at the time of expansion | extension to 10% of elongation rate of the depth direction (H) of the side part 16. FIG.

従って、本発明に係るクッション体２０は、上記第１、第２および第３の何れかの特徴を有する体圧分散型クッション布帛１３が、伸び率１０％に伸長時の伸長応力( Ｆｇ）が位置によって変わる（異なる）幅方向（Ｇ）をフレーム１１の幅方向Ｇに合わせ、そのフレーム１１の幅方向Ｇにおける中央部分に、体圧分散型クッション布帛１３の低伸縮部（中間部１５）を配置して張設されていることを特徴とする。   Therefore, in the cushion body 20 according to the present invention, the body pressure dispersion type cushion fabric 13 having any one of the first, second and third characteristics has an elongation rate (Fg) of 10% when stretched. The width direction (G) that varies (different) depending on the position is aligned with the width direction G of the frame 11, and the low stretchable portion (intermediate portion 15) of the body pressure dispersing cushion fabric 13 is formed at the center in the width direction G of the frame 11. It is arranged and stretched.

本発明によると、クッション体２０のクッション面２１に腰を下ろしたとき、体重が寛骨全体に分散し、寛骨の一部に痛みを感じることなく、長時間着座して疲労感を受けず、座り心地のよい体圧分散型クッション布帛が得られる。
その理由を推考するに、クッション体のクッション面を成すクッション布帛には弾性糸条が、軸芯方向を幅方向Ｇに一直線状に、又は、その軸芯方向を幅方向Ｇに向けて支桿１２の長さ方向（Ｈ）にジグザグに織編み込まれており、その弾性糸条がクッション布帛１３の幅方向Ｇにおいて弾性を発揮しており、その幅方向Ｇにおける伸び率１０％に伸長時の伸長応力Ｆｗが奥行き方向Ｈにおける何れの部位においても同じであっても、奥行き方向Ｈにおける伸縮性（ρ）が幅方向Ｇにおける部位によって異なり、その中間部の奥行き方向Ｈにおける伸縮性（ρ）が少なく伸縮し難い低伸縮部（中間部）１５が奥行き方向Ｈにおける中心部１７から後端縁１８に至るまで連続していると、クッション面に腰を下ろしたとき、その低伸縮部１５に比して奥行き方向Ｈにおいて伸縮性（ρ）が大きく伸縮し易い側部１６が、奥行き方向Ｈにおいて弓形に彎曲して伸び、その彎曲して伸びた分だけ、その側部１６を構成している糸条の奥行き方向Ｈの単位寸法当たりの糸条分布密度（緯糸密度または経糸密度、若しくは、コース密度またはウェール密度）が、支桿１２に固定されているクッション布帛の側縁１４・１４や低伸縮部１５の糸条分布密度（緯糸密度または経糸密度、若しくは、コース密度またはウェール密度）に比して粗くなる。
そうなると、体重に対応してクッション布帛の幅方向Ｇに生じる抗力が、その糸条分布密度が粗くなった彎曲の窪み２３の中心部の幅方向に並んだ１本１本の糸条に集中的に作用することになるので、その窪み２３において幅方向Ｇに軸芯方向が向けられている弾性糸条が伸び、幅方向Ｇにおいて彎曲することになる。
そのようなメカニズムを経て左右の側部１６・１６に寛骨の形状に応じた窪み２３が生じるものと考えられ、その生じた窪み２３に寛骨が密着嵌合すると共に、中間部の低伸縮部１５が、股の間に嵌まり込むように窪み２３に相対して***し、左右の大腿骨を支える恰好になる。
かくして、側部１６の窪み２３と低伸縮部１５に寛骨と大腿骨が触れる接触面積が広がり、寛骨から窪み２３へ、又、大腿骨から低伸縮部１５へと体重が広く分散し、その体重に対応してクッション布帛から受ける反力も寛骨と大腿骨に広く分散することになり、長時間着座して硬さを感じさせることがなく、座り心地がよく疲労感を与えない体圧分散型クッション布帛が得られる。 According to the present invention, when the user sits down on the cushion surface 21 of the cushion body 20, the body weight is distributed over the entire hipbone, without feeling pain in a part of the hipbone, and sitting for a long time without feeling tired. Thus, a body pressure dispersion type cushion fabric having good sitting comfort can be obtained.
For reasoning, the cushion fabric forming the cushion surface of the cushion body is provided with elastic yarns such that the axial direction is aligned in the width direction G or the axial direction is directed in the width direction G. 12 is woven and knitted zigzag in the length direction (H), and the elastic yarn exhibits elasticity in the width direction G of the cushion fabric 13, and the elongation rate in the width direction G is 10%. Even if the elongation stress Fw is the same in any part in the depth direction H, the stretchability (ρ) in the depth direction H differs depending on the part in the width direction G, and the stretchability (ρ) in the depth direction H at the intermediate portion. If the low stretchable part (intermediate part) 15 that is less stretchable and stretches continuously from the center part 17 to the rear end edge 18 in the depth direction H, the lower stretchable part 15 ratio In the depth direction H, the side portion 16 having a large stretchability (ρ) and easily stretchable is bent and extended in a bow shape in the depth direction H, and the side portion 16 is configured by the amount of the bent and extended portion. The yarn distribution density per unit dimension in the depth direction H of the yarn (weft yarn density or warp yarn density, or course density or wale density) is low or low on the side edges 14 and 14 of the cushion fabric fixed to the support 12. It becomes coarser than the yarn distribution density (weft density or warp density, or course density or wale density) of the stretchable part 15.
Then, the drag generated in the width direction G of the cushion fabric corresponding to the body weight is concentrated on each single yarn lined up in the width direction of the central portion of the dent 23 of the curved line in which the yarn distribution density is coarse. Therefore, the elastic yarn having the axial direction directed in the width direction G extends in the recess 23 and bends in the width direction G.
It is considered that the depressions 23 corresponding to the shape of the hipbone are formed in the left and right side parts 16 and 16 through such a mechanism, and the hipbone is closely fitted in the generated depressions 23, and the middle part has a low expansion and contraction. The portion 15 rises relative to the recess 23 so as to fit between the crotch, and is a good way to support the left and right femurs.
Thus, the contact area where the hipbone and the femur are in contact with the dent 23 and the low stretchable part 15 of the side part 16 is widened, and the weight is widely dispersed from the hipbone to the dent 23 and from the femur to the low stretchable part 15; The reaction force received from the cushion fabric corresponding to its weight will be widely dispersed in the hipbone and femur, so that it will sit comfortably for a long time and will not feel firm, and it will give you a comfortable and comfortable body pressure A dispersed cushion fabric is obtained.

思うに、左右の側部１６・１６の窪み２３に相対して***する中間部１５の後端縁１８に続く低伸縮部分２４が、自転車のサドル（座席）のように股の間に嵌まり込み、寛骨と大腿骨の辺りで体重が支えられ、サドルに座った恰好となるので、クッション布帛から寛骨が受ける反力が緩和され、硬さが感じられなくなるものと考えられる。
従って、そのように低伸縮部分２４が自転車のサドルのように大腿骨に作用し易くする上で、低伸縮部（中間部）１５の幅方向Ｇにおけるサイズｇを５〜１５ｃｍ、好ましくは９〜１５ｃｍ、更に好ましくは１０〜１３ｃｍとし、奥行き方向Ｈにおけるサイズｈを２０ｃｍ以上とし、且つ、その低伸縮部（中間部）１５の奥行き方向Ｈにおけるサイズｈを幅方向Ｇにおけるサイズｇの２倍以上とすること、好ましくは低伸縮部（中間部）１５を後端縁１８から前端縁１９に至るまで奥行き方向Ｈに連続させること、又、その中間部（低伸縮部）１５の奥行き方向Ｈにおける伸び率１０％に伸長時の伸長応力Ｆｃが、側部１６の奥行き方向Ｈにおける伸び率１０％に伸長時の伸長応力Ｆｓの少なくとも１．１倍以上に、好ましくは１．２〜１０．０倍に、更に好ましくは１．３〜５．０倍になる程度に、中間部１５の奥行き方向Ｈにおける伸縮性（ρc ）を、側部１６の奥行き方向Ｈにおける伸縮性（ρs ）よりも少なくすること、つまり、低伸縮部（中間部）１５を側部１６に比して硬くして変形し難くすることが、本発明の好ましい実施態様となる。クッション布帛全体の幅方向Ｇおよび奥行き方向Ｈのサイズは、概して３０〜５０ｃｍにするとよい（Ｇ＝３０〜５０ｃｍ、Ｈ＝３０〜５０ｃｍ）。左右の側部１６のサイズ（０．５×Ｇ−ｇ）は、それぞれ１２〜２０ｃｍで概して１５ｃｍ前後になるようにする。 I think, the low expansion / contraction part 24 following the rear end edge 18 of the intermediate part 15 which protrudes relative to the recesses 23 of the left and right side parts 16 and 16 fits between the crotch like a saddle (seat) of a bicycle. In addition, the weight is supported around the hipbone and the femur, and it is a good idea to sit on the saddle. Therefore, it is considered that the reaction force received by the hipbone from the cushion fabric is alleviated and the hardness cannot be felt.
Therefore, in order to make the low stretchable part 24 easily act on the femur like a saddle of a bicycle, the size g in the width direction G of the low stretchable part (intermediate part) 15 is 5-15 cm, preferably 9-9. 15 cm, more preferably 10 to 13 cm, the size h in the depth direction H is 20 cm or more, and the size h in the depth direction H of the low stretchable part (intermediate part) 15 is at least twice the size g in the width direction G Preferably, the low stretchable part (intermediate part) 15 is continued in the depth direction H from the rear end edge 18 to the front end edge 19, and the intermediate part (low stretchable part) 15 in the depth direction H The elongation stress Fc at the time of elongation to 10% elongation is at least 1.1 times the elongation stress Fs at the time of elongation to 10% elongation in the depth direction H of the side portion 16, preferably 1.2-10. 0 times, more preferably to an extent to be 1.3 to 5.0 times, stretchability in the depth direction H of the middle portion 15 ([rho c), elasticity in the depth direction H of the side 16 (ρ s) It is a preferable embodiment of the present invention to make the amount less than that, that is, to make the low expansion / contraction part (intermediate part) 15 harder than the side part 16 and difficult to deform. The size of the entire cushion fabric in the width direction G and the depth direction H is generally 30 to 50 cm (G = 30 to 50 cm, H = 30 to 50 cm). The size of the left and right side portions 16 (0.5 × G-g) is 12 to 20 cm, respectively, and is generally about 15 cm.

弾性糸条には、鞘成分を熱融着性ポリマーとするポリエステル芯鞘複合熱融着性繊維モノフィラメント弾性糸条（例えば、東洋紡績株式会社製品名：ダイヤフローラ）を使用するとよい。低伸縮部１５は、弾性糸条を用いて織編され弾性布帛に、本発明の完成に至る実験段階で補強布片を縫合したように、補強布片２２を縫合、或いは、補強布片２２を接着して形成することも出来、又、弾性布帛の低伸縮部１５に該当する部分に接着剤や塗料を塗着して伸縮性を抑えて形成することも出来る（図３）。   As the elastic yarn, a polyester core-sheath composite heat-fusible fiber monofilament elastic yarn having a sheath component as a heat-fusible polymer (for example, Toyobo Co., Ltd. product name: Diaflora) may be used. The low stretchable portion 15 is woven and knitted using elastic yarns, and the reinforcing cloth piece 22 is stitched to the elastic cloth or the reinforcing cloth piece 22 is stitched to the elastic cloth at the experimental stage leading to the completion of the present invention. Can also be formed by applying an adhesive or a paint to the portion corresponding to the low stretchable portion 15 of the elastic fabric to suppress stretchability (FIG. 3).

しかし、本発明のクッション布帛は、耐久性や触感・風合い、或いは、美観等の点からして、織地または編地として織編することが望ましい。織地として織成する場合、弾性糸条を緯糸に適用することが望ましいが、それを経糸として織り込むことも出来る。
弾性糸条を経糸として織り込む場合は、伸び難い糸条（伸長応力が強く、総じて太手の糸条、以下、太手の糸条と言う。）を低伸縮部１５のサイズｇに応じた長さ分だけ織り込んでから伸び易い糸条（伸長応力が弱く、総じて細手の糸条、以下、細手の糸条と言う。）を織り込んで側部１６を織成する。従って、弾性糸条を経糸に適用する場合、裁断して取り出される複数枚分のクッション布帛の低伸縮部１５と側部１６が繰り返し並んだ横縞（ストライプ）模様状に前後して織り出されることになる。
弾性糸条を緯糸として織り込む場合は、太手の糸条を低伸縮部１５のサイズｇに応じた幅で配列し、細手の糸条を側部１６のサイズ（０．５×Ｇ−ｇ）に応じた幅で配列し、それらを織り幅方向に交互させて縦縞を形成するように整経し、或いは、低伸縮部１５のサイズｇに応じた所要の幅で経糸密度を緻密にし、側部１６のサイズ（０．５×Ｇ−ｇ）に応じた所要の幅で経糸密度を粗くし、裁断して取り出される複数枚分のクッション布帛の低伸縮部１５と側部１６が織り幅方向に交互して縦縞を形成するように織成する。 However, it is desirable that the cushion fabric of the present invention is woven or knitted as a woven fabric or a knitted fabric in terms of durability, tactile sensation, texture, aesthetics, and the like. When weaving as a woven fabric, it is desirable to apply an elastic yarn to the weft, but it can also be woven as a warp.
When weaving elastic yarns as warp yarns, it is necessary to use yarns that are difficult to stretch (stretching stress is strong and generally thick yarns, hereinafter referred to as thick yarns) according to the size g of the low stretchable portion 15. The side portion 16 is woven by weaving yarn that is easy to stretch after weaving for a long time (elongation is weak, generally fine yarn, hereinafter referred to as fine yarn). Therefore, when the elastic yarn is applied to the warp, it is weaved back and forth in a horizontal stripe pattern in which the low stretchable portions 15 and the side portions 16 of the plurality of cushion fabrics to be cut out are repeatedly arranged. become.
When weaving elastic yarns as weft yarns, thick yarns are arranged with a width corresponding to the size g of the low expansion / contraction part 15, and the fine yarns are arranged in the size of the side part 16 (0.5 × G-g). ), And warp so as to form vertical stripes by alternating them in the weaving width direction, or make the warp density dense with the required width according to the size g of the low stretchable part 15, The low stretchable part 15 and the side part 16 of the cushion fabric for a plurality of sheets, which are roughened with a required width corresponding to the size (0.5 × G-g) of the side part 16 and cut out, are woven width. It is woven so as to form vertical stripes alternately in the direction.

クッション布帛を編地として編成する場合、弾性糸条を、コース方向に連続して編み込み、シンカーループとニードルループの間、又は、隣合うニードルループとニードルループの間に挿入して係止すると共に、織地の場合と同様に低伸縮部１５に該当する部分と側部１６に該当する部分に、太手の糸条と細手の糸条を使い分けて配置し、或いは、部分的に編目の密度を変えて縞模様を構成するように編成する。
尚、経糸によってウェール方向に連続して形成されてコース方向において左右隣合うニードルループとニードルループを、ウェール方向にジグザグに続く挿入糸によって連結して編成される経編地では、その左右隣合うニードルループを連結する挿入糸に弾性糸条を適用することも出来る。その何れの編地においても、低伸縮部１５のサイズｇと側部１６のサイズ（０．５×Ｇ−ｇ）に応じた幅で、コース密度やウェール密度を部分的に変え、或いは、太手の糸条と細手の糸条を配置し、裁断して取り出される複数枚分のクッション布帛の低伸縮部１５と側部１６が交互に並んで縞模様を構成するように編成する。 When knitting the cushion fabric as a knitted fabric, the elastic yarn is continuously knitted in the course direction, inserted and locked between the sinker loop and the needle loop, or between the adjacent needle loop and the needle loop. As in the case of the woven fabric, thick yarns and fine yarns are used separately on the portion corresponding to the low stretchable portion 15 and the portion corresponding to the side portion 16, or the density of the stitches is partially Knitting to form a striped pattern by changing.
In addition, in a warp knitted fabric that is continuously formed in the wale direction by warps and is knitted by connecting needle loops and needle loops that are adjacent to each other in the course direction by insertion yarns that follow the zigzag in the wale direction, the left and right sides are adjacent to each other. An elastic thread can be applied to the insertion thread connecting the needle loops. In any of the knitted fabrics, the course density and the wale density are partially changed with a width corresponding to the size g of the low stretchable part 15 and the size of the side part 16 (0.5 × G-g), or thick. Hand yarns and fine yarns are arranged and knitted so that the low stretchable portions 15 and the side portions 16 of a plurality of cushion fabrics to be cut and taken out are alternately arranged to form a striped pattern.

クッション布帛を織地または編地として織編する場合、低伸縮部１５に熱融着性繊維を適用し、それを加熱融着させ、その部分での伸縮性を抑えることが推奨される。
何故なら、熱融着性繊維を適用する場合は、低伸縮部１５に側部１６を構成する糸条よりも太手の糸条を適用したり、低伸縮部１５の経糸密度や緯糸密度、或いは、コース密度やウェール密度を、側部１６の経糸密度や緯糸密度、或いは、コース密度やウェール密度よりも緻密にしたり、低伸縮部１５に補強布片２２を縫合したり、接着剤や塗料を塗着したりする必要がなく、低伸縮部１５と側部１６との伸縮性（ρ）の差異が外観上の差異となってクッション布帛の表面に現れ難く、クッション布帛１３を織編する過程で緯糸密度やコース密度を変える必要がなく、太さや伸縮性の異なる糸条を取り揃える手間も省け、クッション布帛１３が効率的に得られる。
低伸縮部１５と側部１６の間に伸縮性（ρ）の差異を設けるために、低伸縮部１５に熱融着性繊維を適用するとしても、そのことは、低伸縮部１５と側部１６の双方を構成する弾性糸条として、鞘成分を熱融着性ポリマーとする芯鞘複合熱融着性弾性糸条の適用を妨げるものではない。
弾性糸条が、その軸芯方向を一定方向Ｇに一直線状に、又は、その軸芯方向を一定方向Ｇに向け、その方向Ｇに直交する方向（Ｈ）にジグザグに織編み込まれ、クッション布帛全体１３の、その一定方向Ｇにおける伸び率１０％に伸長時の伸長応力Ｆｗが５０Ｎ／５ｃｍ以上であり、クッション布帛全体１３が、その伸び率１０％に伸長後にクッション布帛１３の原形を回復する弾性回復力を有する限り、低伸縮部１５と側部１６の間に伸縮性（ρ）の差異を設けるために、側部１６にだけ伸縮性に富む弾性糸条、つまり伸び易い格別な弾性糸条を適用する必要はない。
クッション布帛の幅方向Ｇ、即ち、弾性糸条の軸芯の向けられる方向における引張弾性強度は、その幅方向Ｇにおいて伸び率１０％に伸長時の伸長応力Ｆｗが１００Ｎ／５ｃｍ以上にするとよい。しかし、その伸長応力Ｆｗが７００Ｎ／５ｃｍ以上になるようにする必要はない。クッション布帛の引張弾性強度が強すぎると、体圧分散に有効に作用する側部１６の窪み２３や低伸縮部１５の***が発生し難くなるからである。 When the cushion fabric is woven or knitted as a woven fabric or knitted fabric, it is recommended to apply a heat-fusible fiber to the low stretchable portion 15 and heat-fuse it to suppress stretchability at that portion.
This is because when a heat-fusible fiber is applied, a yarn that is thicker than the yarn constituting the side portion 16 is applied to the low stretchable portion 15, or the warp density and the weft density of the low stretchable portion 15; Alternatively, the course density or the wale density is made denser than the warp density or the weft density of the side part 16 or the course density or the wale density, or the reinforcing cloth piece 22 is stitched to the low stretchable part 15, or an adhesive or paint. The difference in stretchability (ρ) between the low stretchable portion 15 and the side portion 16 becomes a difference in appearance and hardly appears on the surface of the cushion fabric, and the cushion fabric 13 is woven or knitted. There is no need to change the weft density or the course density in the process, and the cushion fabric 13 can be obtained efficiently without the need to prepare yarns having different thicknesses and stretchability.
Even if a heat-fusible fiber is applied to the low stretchable part 15 in order to provide a difference in stretchability (ρ) between the low stretchable part 15 and the side part 16, this means that the low stretchable part 15 and the side part As an elastic yarn constituting both of the elastic yarns 16, application of a core-sheath composite heat-fusible elastic yarn having a sheath component as a heat-fusible polymer is not prevented.
The elastic yarn is woven and knitted in a zigzag manner in a direction (H) perpendicular to the direction G, with the axial direction in a straight line in the constant direction G, or the axial direction in the constant direction G. The elongation stress Fw at the time of elongation is 50 N / 5 cm or more when the elongation 13 in the constant direction G of the entire 13 is 10%, and the cushion fabric 13 recovers the original shape of the cushion fabric 13 after elongation to the elongation of 10%. In order to provide a difference in stretchability (ρ) between the low stretchable portion 15 and the side portion 16 as long as it has an elastic recovery force, only the side portion 16 is an elastic yarn rich in stretchability, that is, a special elastic yarn that is easy to stretch. There is no need to apply the article.
The tensile elastic strength in the width direction G of the cushion fabric, that is, the direction in which the axis of the elastic yarn is directed, may be 10% elongation in the width direction G, and the elongation stress Fw during elongation is 100 N / 5 cm or more. However, it is not necessary that the elongation stress Fw be 700 N / 5 cm or more. This is because if the cushion fabric has an excessively strong tensile elastic strength, the depressions 23 on the side portions 16 and the bulges on the low expansion / contraction portions 15 that effectively act on body pressure dispersion are less likely to occur.

本発明の効果は、クッション布帛の中間部（１５）の伸縮性を抑え、側部１６に比して伸縮し難くすることによって生じるものであるから、そのクッション布帛１３をクッション体２０のフレーム（支桿１２）に取り付ける際には、中間部（１５）の下側にフレーム１１から当て具を突出させて中間部１５を沈み込み難くし、或いは、中間部１５の前端縁１９と後端縁１８をフレーム１１に突設した治具に固定して中間部１５の奥行き方向Ｈにおける伸縮を積極的に抑えると効果的である。   Since the effect of the present invention is caused by suppressing the stretchability of the intermediate portion (15) of the cushion fabric and making it difficult to expand and contract as compared with the side portion 16, the cushion fabric 13 is formed on the frame of the cushion body 20 ( When attaching to the fulcrum 12), it is difficult to sink the intermediate portion 15 by projecting a pad from the frame 11 to the lower side of the intermediate portion (15), or the front edge 19 and the rear edge of the intermediate portion 15 It is effective to positively suppress expansion and contraction in the depth direction H of the intermediate portion 15 by fixing 18 to a jig protruding from the frame 11.

クッション布帛の後端縁１８に沿った部分２５は、中間部１５と同様に織密度や編密度を緻密にし、又、他の部分よりも太手の糸条を適用し、或いは、他の部分よりも伸び難い糸条を適用して、幅方向Ｇ、つまり弾性糸条の軸芯に平行になる方向において伸び難い低伸縮部２５とすると、体重を載せたとき後端縁１８が沈み込み難く、相対的に側部１６の窪み２３が広がって寛骨との接触面積が広がるので効果的である。
中間部の低伸縮部１５と同様に、後端縁１８に沿った低伸縮部２５にも、熱融着性繊維を混用し、それを加熱融着させ、その部分での伸縮性を抑え、或いは、織編密度を緻密にする等して、端縁の形状を安定にするとよい。
同様に、サイズ（０．５×Ｇ−ｇ）が１２〜２０ｃｍ、概して１５ｃｍ前後となる左右の側部１６の側縁１４・１４にも、補強と形状安定を兼ねて熱融着性繊維を混用し、それを加熱融着させ、或いは、織編密度を緻密にして硬く仕上げることも出来る。 The portion 25 along the rear edge 18 of the cushion fabric is dense in woven density and knitting density as in the intermediate portion 15, and is applied with a thread that is thicker than other portions, or other portions. If the lower stretchable portion 25 is applied in the width direction G, that is, in the direction parallel to the axis of the elastic yarn, by applying a yarn that is more difficult to stretch, the trailing edge 18 is less likely to sink when the weight is applied. This is effective because the recess 23 of the side portion 16 relatively expands and the contact area with the hipbone increases.
Similar to the low stretchable part 15 in the middle part, the heat-fusible fiber is also mixed in the low stretchable part 25 along the rear edge 18 to heat-fuse it, thereby suppressing the stretchability at that part, Alternatively, the shape of the edge may be stabilized by, for example, increasing the density of the knitting and knitting.
Similarly, the heat-fusible fibers are also applied to the side edges 14 and 14 of the left and right side portions 16 having a size (0.5 × G-g) of 12 to 20 cm and generally around 15 cm for both reinforcement and shape stability. They can be mixed and heat-sealed, or the woven / knitted density can be made fine and hard.

支桿１２は、その前後両端部分２６・２７を下向きに彎曲させ、その支桿１２の形状に沿ってクッション布帛の後端縁１８と前端縁１９を、それぞれ⊂形と⊃形に折り返した恰好にすると、身体が触れたときの感触が柔らかくなり、その部分を補強したり、緩衝材を取り付ける手間も省けるので好都合である。
支桿（１２）は、左右両側縁１４・１４と同様に、後端縁１８と前端縁１９に取り付けることも出来、その支桿（１２）によって後端縁１８と前端縁１９を補強し、クッション体２０の全体の構造を安定にするとよい。
クッション面２１は、装飾性カバー（表面材）で被覆することが出来、又、クッション面２１の上にポリウレタンフォーム等のクッション材を重ねることも出来る。その場合、そのクッション材の上面に寛骨や大腿骨の形状に合わせた凹凸（窪み）を付けることは格別必要とされない。張設されたクッション布帛が平板になっていても、体重が加わると窪み２３が生じるからである。 The support 12 is bent with its front and rear end portions 26 and 27 bent downward, and the rear end edge 18 and the front end edge 19 of the cushion fabric are folded back into a saddle shape and a saddle shape, respectively, along the shape of the support 12. In this case, the touch when touched by the body becomes soft, and it is convenient because it is possible to save the trouble of reinforcing the part and attaching the cushioning material.
The support (12) can be attached to the rear end edge 18 and the front end edge 19 in the same manner as the left and right side edges 14 and 14, and the rear end edge 18 and the front end edge 19 are reinforced by the support (12). It is preferable to stabilize the entire structure of the cushion body 20.
The cushion surface 21 can be covered with a decorative cover (surface material), and a cushion material such as polyurethane foam can be stacked on the cushion surface 21. In that case, it is not particularly necessary to provide the upper surface of the cushion material with irregularities (dents) that match the shape of the hipbone or femur. This is because, even if the stretched cushion fabric is a flat plate, the depression 23 is generated when weight is added.

中間部１５の奥行き方向Ｈにおける伸縮性（ρc ）と、側部１６の奥行き方向Ｈにおける伸縮性（ρs ）との差異が、外観上の差異となってクッション布帛の表面に現れないようにするには、クッション布帛の表面をカットパイル、ループパイル、起毛毛羽等の立毛面とし、又、クッション布帛を表地と裏地との２枚の布帛を連結糸で連結した二重構造にし、その表面に現れない裏地の中間部１５と側部１６との間に伸縮性（ρ）の差異を付けるとよい。 The difference between the stretchability (ρ c ) in the depth direction H of the intermediate portion 15 and the stretchability (ρ s ) in the depth direction H of the side portion 16 does not appear on the surface of the cushion fabric as a difference in appearance. To make the cushion fabric, the surface of the cushion fabric is a raised surface such as a cut pile, loop pile, and raised fluff, etc., and the cushion fabric is made into a double structure in which two fabrics, a front material and a lining material, are connected by a connecting thread, A difference in stretchability (ρ) may be provided between the intermediate portion 15 and the side portion 16 of the lining that does not appear on the surface.
