クッション体とシェルとの間に面ファスナが介在する構成では、面ファスナの厚みによりクッション体とシェルとの間に隙間が形成されやすく、見栄えの悪化が懸念される。そこで、本発明は、対象物により見栄え良く取り付けることが可能なクッション体を提供する。 In a configuration in which a hook-and-loop fastener is interposed between the cushion body and the shell, a gap is likely to be formed between the cushion body and the shell due to the thickness of the hook-and-loop fastener, and there is concern about deterioration in appearance. Accordingly, the present invention provides a cushion body that can be attached to an object in a more attractive manner.

上記課題を解決する手段として、本発明のクッション体は、対象物に取り付けられて使用されるクッション体であって、対象物に結合部材を介して結合される板状の基材と、基材上に設けられるパッド材と、パッド材を覆う表皮材と、を有する。基材が、対象物に当接してパッド材を裏支えするパッド支持部と、表皮材の端末部が重ね合わせ状に係合される外周縁部と、対象物から離間する方向に凹む凹部であって結合部材が内部に配置される凹部と、を有する。 As means for solving the above problems, the cushion body of the present invention is a cushion body that is attached to an object and used, and comprises a plate-like base material that is connected to the object via a connecting member; It has a pad material provided thereon and a skin material covering the pad material. The base material consists of a pad supporting portion that contacts the object and supports the pad material from the back, an outer peripheral edge portion that engages the end portion of the skin material in a superimposed manner, and a concave portion that is recessed in the direction away from the object. a recess in which the coupling member is disposed.

ここで、表皮材の端末部が基材の外周縁部に対して「重ね合わせ状に係合される」状態とは、表皮材の端末部が基材の外周縁部の表裏どちらかの面上に直接重ね合わされて係合される状態や、パッド材を間に挟んで表皮材の端末部がパッド材を先細り状に押し潰すように張られて基材の外周縁部の裏面に重ね合わされて係合される状態を指す。 Here, the state in which the end portion of the skin material is "engaged in an overlapped manner" with the outer peripheral edge portion of the base material means that the end portion of the skin material is on either the front or back side of the outer peripheral edge portion of the base material. A state in which the surface material is directly overlaid and engaged therewith, or a state in which the terminal portion of the skin material is stretched so as to taper down the pad material with the pad material sandwiched therebetween and is overlaid on the back surface of the outer peripheral edge portion of the base material. It refers to the state of being engaged by

Peripheral edges of the substrates extend obliquely toward the object so as to gradually narrow the gap between them. According to the above configuration, the cushion body can be provided so that the thickness of the peripheral edge of the object gradually decreases. In addition, since the outer peripheral edge of the base material has a bent shape, the bending rigidity and torsional rigidity of the base material are appropriately enhanced, and the outer peripheral edge part of the base material is less likely to warp upward from the object.

また、本発明のクッション体は、更に次のように構成されていても良い。基材の外周縁部が、結合部材の結合力により、対象物に押し付けられた状態に設けられる。上記構成によれば、クッション体の周縁を対象物に密着させて互いの間に隙間が形成されないより見栄えの良い状態に取り付けることができる。 Moreover, the cushion body of the present invention may be further configured as follows. The outer peripheral edge of the base material is provided in a state of being pressed against the object by the coupling force of the coupling member. According to the above configuration, the peripheral edge of the cushion body can be brought into close contact with the object, and the cushion body can be attached in a more attractive state without forming a gap between them.

また、本発明のクッション体は、更に次のように構成されていても良い。基材の外周縁部が、凹部の外側の壁部を成す。上記構成によれば、基材の凹部を、斜めに延出する外周縁部と合理的に組み合わせた構成とすることができる。なおかつ、凹部に配置される結合部材の結合力により、基材の外周縁部を対象物へと適切に引き込むことができる。 Moreover, the cushion body of the present invention may be further configured as follows. The outer peripheral edge of the base material forms the outer wall of the recess. According to the above configuration, the concave portion of the base material can be rationally combined with the obliquely extending outer peripheral edge portion. In addition, the outer peripheral edge of the base material can be drawn into the object appropriately by the coupling force of the coupling member arranged in the recess.

また、本発明のクッション体は、更に次のように構成されていても良い。クッション体が、更に、表皮材の端末部を基材の外周縁部に重ね合わせ状に縫い付けるアウトステッチ部を有する。上記構成によれば、表皮材の端末部を基材の外周縁部に見栄え良く固定することができる。 Moreover, the cushion body of the present invention may be further configured as follows. The cushion body further has an outstitch portion for sewing the end portion of the skin material to the outer peripheral edge portion of the base material in an overlapping manner. According to the above configuration, the end portion of the skin material can be fixed to the outer peripheral edge portion of the base material with good appearance.

また、本発明のクッション体は、更に次のように構成されていても良い。表皮材の端末部が、基材の外周縁部上に重ね合わされる側に折り返される折返し部分を有し、折返し部分と直接的な２枚重ね或いは基材の外周縁部を折返し部分との間に挟む間接的な２枚重ねでアウトステッチ部により基材の外周縁部に縫い付けられる。上記構成によれば、表皮材の端末部を、裁断面が外部に露出しない見栄えの良い形に仕上げることができる。 Moreover, the cushion body of the present invention may be further configured as follows. The terminal part of the skin material has a folded part that is folded back on the outer peripheral edge part of the base material, and the folded part is directly doubled or between the folded part and the outer peripheral edge part of the base material. It is sewn to the outer peripheral edge of the base material by the outstitch part by indirect two-ply sandwiching. According to the above configuration, the end portion of the skin material can be finished in a good-looking shape in which the cut surface is not exposed to the outside.

また、本発明のクッション体は、更に次のように構成されていても良い。クッション体が、更に、基材の外周縁部とこの外周縁部上に重ね合わされる表皮材の端末部との間に挟まれてこれらとアウトステッチ部により共縫いされる面状の加飾部材を有する。上記構成によれば、加飾部材の追加により、クッション体の周縁をより見栄え良く仕上げることができる。そして、この加飾部材を、表皮材の端末部と基材の外周縁部との間に合理的に設けることができる。 Moreover, the cushion body of the present invention may be further configured as follows.

以下に、本発明を実施するための形態について、図面を用いて説明する。 EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated using drawing.

《第１の実施形態》
（クッション体１０の概略構成）
始めに、本発明の第１の実施形態に係るクッション体１０の構成について、図１～図３を用いて説明する。なお、以下の説明において、前後上下左右等の各方向を示す場合には、各図中に示されたそれぞれの方向を指すものとする。 <<1st Embodiment>>
(Schematic configuration of cushion body 10)
First, the configuration of the cushion body 10 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. In the following description, when directions such as front, back, up, down, left, and right are indicated, they refer to the respective directions shown in the respective drawings.

図１に示すように、本実施形態に係るクッション体１０は、自動車のシート１に取り付けられて着座者の荷重を柔らかく支持するシート用クッションとして構成される。シート１は、いわゆるバケットシートの構成とされ、着座者の尻部や腰部、それに肩部を深く包んで固定することが可能な高いホールド性を備えた構成とされる。 As shown in FIG. 1, a cushion body 10 according to the present embodiment is configured as a seat cushion that is attached to a seat 1 of an automobile and that softly supports the load of a seated person. The seat 1 is configured as a so-called bucket seat, and is configured to have a high holdability capable of deeply wrapping and fixing the buttocks, waist, and shoulders of a seated person.

具体的には、シート１は、着座者の背部を支持するシートバック２と、着座者の尻部を支持するシートクッション３と、を備える。シートバック２とシートクッション３とは、それぞれ、凹湾曲面状に成形された１枚のパネル状のシェルＳにより、それらの基本骨格が形成されている。シェルＳは、炭素繊維もしくはガラス繊維を使用した繊維強化プラスチック（ＦＲＰ）により形成されている。 Specifically, the seat 1 includes a seat back 2 that supports the back of the seated person, and a seat cushion 3 that supports the buttocks of the seated person. The seat back 2 and the seat cushion 3 each have their basic skeletons formed by a single panel-like shell S molded into a concavely curved surface. The shell S is made of fiber reinforced plastic (FRP) using carbon fiber or glass fiber.

シェルＳは、シートバック２を構成する部分とシートクッション３を構成する部分とのそれぞれで、左右のへりが着座者側に向かって立ち上がる形に曲げられている。それにより、シェルＳは、着座者の尻部や大腿部、腰部、肩部、それに脇腹等の体側を覆って、着座者自身が踏ん張らなくても、車両から伝わる横Ｇに対して着座者の身体の位置を適切に保持できるようになっている。また、シェルＳは、着座者の尻部を深く沈み込ませて支持する構成とされ、それにより着座者の骨盤や背骨の角度を適正化した状態に保持する構成とされる。 In the shell S, the left and right edges of the portion forming the seat back 2 and the portion forming the seat cushion 3 are bent in such a manner that the left and right edges rise toward the occupant. As a result, the shell S covers the occupant's buttocks, thighs, waist, shoulders, flanks, and other body sides, so that the occupant is able to absorb the lateral G force transmitted from the vehicle even if the occupant does not step on it. to properly maintain the body position of the Further, the shell S is configured to deeply sink and support the buttocks of the seated person, thereby maintaining the angle of the pelvis and spine of the seated person in an appropriate state.

クッション体１０は、上記シェルＳの着座面上の所々の箇所に、浮島状に分かれて複数設けられている。具体的には、各クッション体１０は、それぞれ、シェルＳの着座面に対して、後述する面ファスナ１４Ａ，１４Ｂ（図２～図３参照）により着脱可能なように貼り付けられている。ここで、シェルＳが、本発明の「対象物」に相当し、面ファスナ１４Ａ，１４Ｂが、本発明の「結合部材」に相当する。 A plurality of cushion bodies 10 are provided at various places on the seating surface of the shell S so as to be divided like floating islands. Specifically, each cushion body 10 is detachably attached to the seating surface of the shell S by hook-and-loop fasteners 14A and 14B (see FIGS. 2 and 3), which will be described later. Here, the shell S corresponds to the "object" of the present invention, and the hook-and-loop fasteners 14A and 14B correspond to the "joint member" of the present invention.

各クッション体１０は、それぞれ、パッド厚が１０ｍｍ程度の薄型のクッション構造とされる。それにより、各クッション体１０は、車両の挙動をレスポンス良く正確に着座者に伝えられるようになっている。したがって、シート１が運転席に適用される場合には、車両の挙動をドライバーに適切に伝えることができる。 Each cushion body 10 has a thin cushion structure with a pad thickness of about 10 mm. As a result, each cushion body 10 can accurately transmit the behavior of the vehicle to the seated occupant with good response. Therefore, when the seat 1 is applied to the driver's seat, it is possible to appropriately convey the behavior of the vehicle to the driver.

各クッション体１０は、シェルＳ上にクッション性を持たせたい必要箇所にのみ分散して配置されている。具体的には、各クッション体１０は、シェルＳの着座者の背部、腰部、尻部及び大腿部を支持するそれぞれの部分と、これら左右のへりから立ち上がって着座者の肩部、脇腹、腰部、尻部及び大腿部の体側を覆うそれぞれの部分と、に浮島状に分かれて設けられている。各クッション体１０は、シェルＳの着座面上において互いに離間して配置されており、互いの間からシェルＳの着座面が外部に露出する構成とされる。 The respective cushion bodies 10 are dispersedly arranged only at necessary portions on the shell S where it is desired to have cushioning properties. Specifically, each of the cushion bodies 10 includes portions of the shell S that support the back, waist, buttocks, and thighs of the seated person, and the left and right edges that support the shoulders, flanks, and sides of the seated person. It is provided separately in a floating island shape to each part covering the body side of the waist, buttocks and thighs. The respective cushion bodies 10 are arranged on the seating surface of the shell S so as to be spaced apart from each other, and the seating surface of the shell S is exposed to the outside from between them.

このように、各クッション体１０がシェルＳ上の必要箇所にのみ分散して配置されていることにより、ウレタン使用料を最小限に抑え、重量増大を適切に抑制することができる。また、各クッション体１０の間から、繊維強化プラスチックから成る高性能なシェルＳの着座面である表面を外部に露出させて、シート１の見栄え向上を図ることができる。 In this way, each cushion body 10 is dispersed and arranged only at the necessary locations on the shell S, so that the amount of urethane used can be minimized and the increase in weight can be appropriately suppressed. In addition, the appearance of the seat 1 can be improved by exposing the surface, which is the seating surface of the high-performance shell S made of fiber-reinforced plastic, from between the cushion bodies 10 to the outside.

（クッション体１０の各部構成）
続いて、各クッション体１０の具体的な構成について詳しく説明する。なお、各クッション体１０は、シェルＳ上に設けられるそれぞれの位置に応じた形状とされるが、それぞれの基本構造は同一のものとなっている。したがって、以下では、これらを代表して、図１のＩＩ－ＩＩ線が付されたクッション体１０の構成について詳しく説明する。 (Construction of Each Part of Cushion Body 10)
Next, a specific configuration of each cushion body 10 will be described in detail. Each cushion body 10 has a shape corresponding to each position provided on the shell S, but each has the same basic structure. Accordingly, the configuration of the cushion body 10 indicated by the line II-II in FIG. 1 will be described in detail below as a representative of them.

図２～図３に示すように、クッション体１０は、板状の基材１１と、基材１１上に設けられるパッド材１２と、パッド材１２を覆う表皮材１３と、を有する。クッション体１０は、基材１１の裏面とシェルＳの着座面との間に設けられる雄雌の面ファスナ１４Ａ，１４Ｂ同士の結合により、シェルＳに対して着脱可能なように結合されている。 As shown in FIGS. 2 and 3, the cushion body 10 has a plate-like base material 11, a pad material 12 provided on the base material 11, and a skin material 13 covering the pad material 12. As shown in FIGS. The cushion body 10 is detachably connected to the shell S by connecting male and female hook-and-loop fasteners 14A and 14B provided between the back surface of the base material 11 and the seating surface of the shell S. As shown in FIG.

（基材１１）
基材１１は、ポリプロピレン（ＰＰ）樹脂を略平板状に熱プレス成形した樹脂成形品から成る。基材１１は、その設けられるシェルＳの着座面に沿った形に成形されている。基材１１は、シェルＳの着座面に面当接した状態にセットされてパッド材１２を裏支えするパッド支持部１１Ａを有する。また、基材１１は、その外周縁の周方向の全域に、表皮材１３の端末部１３Ｂがバインディング処理によって重ね合わせ状に縫い合わされる外周縁部１１Ｂを有する。 (Base material 11)
The base material 11 is made of a resin molded article obtained by heat-press molding a polypropylene (PP) resin into a substantially flat plate shape. The base material 11 is shaped along the seating surface of the shell S on which it is provided. The base material 11 has a pad supporting portion 11A which is set in surface contact with the seating surface of the shell S to support the pad material 12 from the back. Moreover, the base material 11 has an outer peripheral edge portion 11B over the entire circumferential direction of the outer peripheral edge thereof, to which the end portions 13B of the upholstery material 13 are sewn together by binding.

また、基材１１は、その外周縁に沿った外周縁よりも内側の周方向の全域に、シェルＳの着座面から離間する方向に凹む凹部１１Ｃが連続的に形成されている。凹部１１Ｃは、上述した外周縁部１１Ｂを外側の壁部とする横断面略台形状に凹んだ形状とされる。 In addition, the base material 11 is continuously formed with a recess 11</b>C recessed in a direction away from the seating surface of the shell S along the outer peripheral edge of the substrate 11 in the entire circumferential direction inside the outer peripheral edge. The recessed portion 11C has a substantially trapezoidal cross-sectional shape with the outer peripheral edge portion 11B as an outer wall portion.

外周縁部１１Ｂは、凹部１１Ｃの凹んだ底の天板部分の外周縁からシェルＳの着座面に向かって斜め外側に折れ曲がり状に延び出す傾斜板となっている。すなわち、外周縁部１１Ｂは、シェルＳの着座面に向かって互いの隙間を徐々に狭めるように斜めに延出する形状とされている。 The outer peripheral edge portion 11B is an inclined plate that bends and extends obliquely outward toward the seating surface of the shell S from the outer peripheral edge of the top plate portion of the recessed bottom of the recess 11C. That is, the outer peripheral edge portion 11</b>B extends obliquely toward the seating surface of the shell S so as to gradually narrow the gap therebetween.

凹部１１Ｃの内側の壁部１１Ｄも、凹部１１Ｃの凹んだ底の天板部分の内周縁からシェルＳの着座面に向かって斜め内側に折れ曲がり状に延び出す傾斜板となっている。内側の壁部１１Ｄは、その斜めに延び出した先の位置で、シェルＳに当接するパッド支持部１１Ａと繋がっている。 The inner wall portion 11D of the recess 11C is also an inclined plate that bends and extends obliquely inward toward the seating surface of the shell S from the inner peripheral edge of the top plate portion of the recessed bottom of the recess 11C. The inner wall portion 11D is connected to the pad support portion 11A that abuts on the shell S at the tip of the oblique extension.

基材１１の外周縁部１１Ｂは、図３に示すように、基材１１のパッド支持部１１ＡがシェルＳの着座面上に当てられた初期当たりの状態では、その先端がシェルＳの着座面上に弱く当てられるか、或いはシェルＳの着座面上から僅かに浮いた状態にセットされる。しかし、基材１１の外周縁部１１Ｂは、図２に示すように、後述する凹部１１Ｃの天板部分の裏面に設けられた雄の面ファスナ１４Ａが、シェルＳの着座面上の対応する位置に設けられた雌の面ファスナ１４Ｂに押し付けられて結合されることにより、その先端がシェルＳの着座面上に強く押し付けられた状態にセットされる。 As shown in FIG. 3, when the pad supporting portion 11A of the base member 11 is in contact with the seating surface of the shell S in the initial contact state, the tip of the outer peripheral edge portion 11B of the base member 11 touches the seating surface of the shell S. It is set in a state where it is slightly applied to the top of the shell S or is slightly raised from the seating surface of the shell S. However, the outer peripheral edge portion 11B of the base material 11, as shown in FIG. By being pressed against and coupled with the female hook-and-loop fastener 14B provided in the shell S, the tip thereof is set in a state in which it is strongly pressed onto the seating surface of the shell S.

その結果、基材１１の外周縁部１１Ｂは、シェルＳの着座面との間に隙間が形成されない状態に保持される。基材１１は、その外周縁部１１Ｂが周方向の全域に亘って上記のような折れ曲がり形状とされていることで、曲げ剛性及び捩り剛性が高められた構成とされる。基材１１の外周縁部１１Ｂは、その凹部１１Ｃの凹んだ底の天板部分からの折れ曲がり角度が、周方向の全域に亘って略同一の角度に設定されている。 As a result, the outer peripheral edge portion 11B of the base material 11 is held in a state in which no gap is formed between the outer peripheral edge portion 11B and the seating surface of the shell S. The base material 11 is configured such that the bending rigidity and the torsional rigidity are enhanced by forming the outer peripheral edge portion 11B of the base material 11 into the bent shape as described above over the entire circumferential direction. The outer peripheral edge portion 11B of the base material 11 is bent at substantially the same angle from the top plate portion of the recessed bottom of the recess 11C over the entire circumferential direction.

上記基材１１の外周縁部１１Ｂの折れ曲がりにより、クッション体１０は、その周縁の厚みがシェルＳに向かってなだらかに減少していく形状とされている。また、基材１１は、その凹部１１Ｃの内側の壁部１１Ｄも凹部１１Ｃの天板部分からシェルＳに向かって斜めに折れ曲がる形状とされていることで、凹部１１Ｃの天板部分とパッド支持部１１Ａとの間の段差が緩和された構成とされる。それにより、上記基材１１の段差がパッド材１２を介して着座者の身体に異物感を感じさせる座り心地の悪化が軽減されている。 Due to the bending of the outer peripheral edge portion 11B of the base material 11, the thickness of the peripheral edge of the cushion body 10 gradually decreases toward the shell S. As shown in FIG. In the base material 11, the wall portion 11D inside the concave portion 11C is also bent obliquely from the top plate portion of the concave portion 11C toward the shell S, so that the top plate portion of the concave portion 11C and the pad supporting portion 11A is relaxed. As a result, deterioration in sitting comfort caused by the level difference of the base material 11, which causes the body of the seated person to feel a foreign object through the pad material 12, is reduced.

（基材１１）
パッド材１２は、その厚み（パッド厚）が一定となる板状のスラブウレタンにより形成されている。パッド材１２は、基材１１の外周縁に沿った、基材１１よりもひとまわり小さな外径をもつ板形状に形成されている。 (Base material 11)
The pad material 12 is formed of a plate-shaped slab urethane having a constant thickness (pad thickness). The pad material 12 is formed in a plate shape along the outer periphery of the base material 11 and having an outer diameter slightly smaller than that of the base material 11 .

パッド材１２は、基材１１に対して、パッド支持部１１Ａ、凹部１１Ｃの内側の壁部１１Ｄ及び凹部１１Ｃの天板部分の上にこれらの全域に亘って重ね合わされる形にセットされる。詳しくは、パッド材１２は、その外周縁が、基材１１の凹部１１Ｃの天板部分の外周縁と周方向の全域に亘って揃う形にセットされる。すなわち、パッド材１２は、基材１１の外周縁部１１Ｂ上には乗り上がらずに、基材１１のパッド支持部１１Ａから凹部１１Ｃの天板部分に亘る領域上に重ね合わされる形にセットされて、これらにより裏側から面状に支持される構成とされる。 The pad material 12 is set on the base material 11 so as to be superimposed on the pad supporting portion 11A, the inner wall portion 11D of the recess 11C, and the top plate portion of the recess 11C over the entire area thereof. Specifically, the pad material 12 is set so that its outer peripheral edge is aligned with the outer peripheral edge of the top plate portion of the concave portion 11</b>C of the base material 11 over the entire circumferential direction. That is, the pad material 12 is set in such a manner that it does not ride on the outer peripheral edge portion 11B of the base material 11, but overlaps the area extending from the pad support portion 11A of the base material 11 to the top plate portion of the concave portion 11C. , and are supported in a planar manner from the rear side.

（表皮材１３）
表皮材１３は、合成皮革により形成されている。表皮材１３は、基材１１の外周縁に沿った、基材１１よりもひとまわり大きな外径をもつ形状に形成されている。表皮材１３は、基材１１の上にセットされたパッド材１２に表側から全域に亘って被覆される被覆部１３Ａと、基材１１の外周縁部１１Ｂに周方向の全域に亘ってバインディング処理により重ね合わされた状態に縫い合わされる外周縁の端末部１３Ｂと、を有する。 (Skin material 13)
The skin material 13 is made of synthetic leather. The skin material 13 is formed along the outer periphery of the base material 11 and has an outer diameter slightly larger than that of the base material 11 . The skin material 13 has a covering portion 13A that covers the entire area from the front side of the pad material 12 set on the base material 11, and a binding treatment that covers the entire circumference of the outer peripheral edge portion 11B of the base material 11. and a terminal portion 13B of the outer peripheral edge that is sewn together in an overlapping state.

表皮材１３の端末部１３Ｂは、基材１１の外周縁部１１Ｂの表面上に重ね合わされる部分と、基材１１の外周縁部１１Ｂの裏側へと折り返されて外周縁部１１Ｂの裏面上に重ね合わされる折返し部分１３Ｃと、を備える構成とされる。上記表皮材１３の端末部１３Ｂは、先ず、その基材１１の外周縁部１１Ｂの表面上に重ね合わされる部分が、接着剤（接着層Ａ）により外周縁部１１Ｂの表面上に接着される。 The terminal portion 13B of the skin material 13 is folded back to the back side of the outer peripheral edge portion 11B of the base material 11 and the portion overlapped on the surface of the outer peripheral edge portion 11B of the base material 11. and a folded portion 13C to be overlapped. The terminal portion 13B of the skin material 13 is first adhered to the surface of the outer peripheral edge portion 11B with an adhesive (adhesive layer A) at the portion that is superimposed on the surface of the outer peripheral edge portion 11B of the base material 11. .

次に、表皮材１３の端末部１３Ｂは、折返し部分１３Ｃが基材１１の外周縁部１１Ｂの裏面上に重ね合わされる形に折り返される。それにより、表皮材１３の端末部１３Ｂは、その基材１１の外周縁部１１Ｂの表面上に重ね合わされる部分と裏側の折返し部分１３Ｃとが、基材１１の外周縁部１１Ｂを間に挟む間接的な２枚重ねの状態となる。そしてその状態で、表皮材１３の端末部１３Ｂは、基材１１の外周縁部１１Ｂに対して、外周縁部１１Ｂの内周縁に沿って縫い糸が走るように縫われるアウトステッチ部Ｔにより、折返し部分１３Ｃと共に基材１１の外周縁部１１Ｂを間に挟むように重ね合わせ状に縫い付けられる。 Next, the terminal portion 13B of the skin material 13 is folded back so that the folded portion 13C is overlaid on the back surface of the outer peripheral edge portion 11B of the base material 11 . As a result, the terminal portion 13B of the skin material 13 sandwiches the outer peripheral edge portion 11B of the base material 11 between the portion overlapped on the surface of the outer peripheral edge portion 11B of the base material 11 and the folded portion 13C on the back side. It becomes an indirect two-ply state. In this state, the terminal portion 13B of the upholstery material 13 is folded back by the outstitch portion T sewn so that the sewing thread runs along the inner peripheral edge of the outer peripheral edge portion 11B with respect to the outer peripheral edge portion 11B of the base material 11. Together with the portion 13C, the base material 11 is sewn in an overlapped manner so as to sandwich the outer peripheral edge portion 11B of the base material 11 therebetween.

アウトステッチ部Ｔは、基材１１の外周縁部１１Ｂに沿って周方向の全域に亘って無端状に形成されている。上記縫い付けにより、表皮材１３の端末部１３Ｂは、その裁断面が基材１１の裏側に回し込まれてシェルＳとの間に見栄え良く隠される状態となる。更に、表皮材１３の端末部１３Ｂは、基材１１の外周縁部１１Ｂを包むことで外周縁部１１Ｂの端面を外部に露出させないよう見栄え良く被覆する。 The outstitch portion T is formed endlessly along the outer peripheral edge portion 11B of the base material 11 over the entire circumferential direction. By the sewing, the cut surface of the end portion 13B of the upholstery material 13 is wrapped around the back side of the base material 11 and hidden between the shell S with good appearance. Further, the terminal portion 13B of the skin material 13 wraps the outer peripheral edge portion 11B of the base material 11 to cover the end face of the outer peripheral edge portion 11B with good appearance so as not to be exposed to the outside.

上記表皮材１３は、その端末部１３Ｂがアウトステッチ部Ｔにより基材１１の外周縁部１１Ｂに重ね合わせ状に縫い付けられることにより、そのテンションによりパッド材１２の外周縁部分を基材１１の凹部１１Ｃの天板部分上に押し付ける。それにより、パッド材１２は、その外周縁部分の厚みが、外周縁に向かって先細り状に減少していく形に仕上げられる。 The end portion 13B of the skin material 13 is sewn to the outer peripheral edge portion 11B of the base material 11 by the outstitch portion T in a superimposed manner, so that the outer peripheral edge portion of the pad material 12 is attached to the base material 11 by the tension thereof. It is pressed onto the top plate portion of the recess 11C. As a result, the pad material 12 is finished in such a manner that the thickness of the outer peripheral portion thereof tapers off toward the outer peripheral edge.

その結果、クッション体１０は、アウトステッチ部Ｔを境に形成される、パッド材１２を包む表皮材１３の被覆部１３Ａの外周縁部分と、基材１１の外周縁部１１Ｂ上に重ね合わせ状に縫い付けられる表皮材１３の端末部１３Ｂと、の間の段差が緩和された形状とされる。また、クッション体１０は、上記基材１１の外周縁部１１Ｂの折れ曲がりにより、その外周縁の厚みがシェルＳに向かってなだらかに減少していく形状とされる。 As a result, the cushion body 10 is superimposed on the outer peripheral edge portion of the covering portion 13A of the skin material 13 that wraps the pad material 12 and the outer peripheral edge portion 11B of the base material 11 formed with the outstitch portion T as a boundary. The shape is such that the step between the end portion 13B of the upholstery material 13 to be sewn to and the end portion 13B is relaxed. The thickness of the outer peripheral edge of the cushion body 10 gradually decreases toward the shell S due to the bending of the outer peripheral edge portion 11B of the base material 11 .

（面ファスナ１４Ａ，１４Ｂ）
図３に示すように、面ファスナ１４Ａ，１４Ｂは、基材１１の凹部１１Ｃの天板部分の裏面に設けられた雄の面ファスナ１４Ａと、シェルＳの着座面上の対応する位置に設けられた雌の面ファスナ１４Ｂと、の組み合わせから成る。雄の面ファスナ１４Ａは、その雌の面ファスナ１４Ｂと対向する側の面上に、無数のフック状の起毛が密集して形成された構成とされる。雌の面ファスナ１４Ｂは、その雄の面ファスナ１４Ａと対向する側の面上に、無数のループ状の起毛が密集して形成された構成とされる。 (Velcro fasteners 14A, 14B)
