を損なうものであつた。 The gusset part 2 is provided with a gusset cloth 2a between the front and back molding sheets 1a and 1b of the air bag main body C, and divides the gusset cloth 2a into two band-like cloths, with one side of each of the band-like cloths turned inward. It is inserted into the bag and the mating surfaces of the tips are glued to each other, so that when the air bag main body C is deflated, it is folded inward from the adhesive part 3 of the gusset part 2. (8th
(Fig.) However, when the air bag C having the above-mentioned gusset structure is inflated, the gusset portion 2 opens into a planar shape as shown in Fig. 7 due to the internal pressure of the air bag C.
When the internal pressure further increases, it bulges outward as shown by the two-dot chain line and generates a loud thumping sound. This sound is generated when the gusset cloth 2a is reversed, and is generated when the air bag C is fully inflated or when the driver leans on the support surface, but it is a harsh sound, and the air support mechanism This spoiled the image of a relatively high-class seat equipped with

音を発生することがないものである。 Therefore, even when the air bag is inflated or when the driver leans on the support surface of the seat, unpleasant noises caused by the gusset fabric being reversed will not be generated.
（実施例）
以下、本考案の一実施例を図面に基づいて説明
する。(Example) Hereinafter, an example of the present invention will be described based on the drawings.
図中Ａはマチ部Ｂを備えたエアーバツグであ

つて封着して断面略三角形状のエアーバツグ本体
Ａを形成し、このエアーバツグ本体Ａ内の対向面
間には吊り布Ｃを設けたものである。 In the figure, A is an air bag with a gusset B, and the gusset B is formed on one side of two molding sheets a 1 and a 2 made of thermoplastic soft urethane resin and formed into rectangular planes, and the remaining 3 The sides are sealed by heat welding to form an air bag main body A having a substantially triangular cross section, and a hanging cloth C is provided between opposing surfaces within the air bag main body A.
前記マチ部Ｂは、両成形用シートa1，a2の周縁
部に沿つて帯状のマチ布b1，b2一辺を熱溶着し、
これらマチ布b1，b2を共にエアーバツグＡ内へ入

縁間に挾入し、シートa1，a2と一緒に熱溶着した
ものである。 The gusset part B is formed by thermally welding one side of band-shaped gusset cloth b 1 and b 2 along the peripheral edges of both molding sheets a 1 and a 2 ,
These gusset cloths b 1 and b 2 are both inserted into the air bag A, and the mating surfaces of their tips are bonded together by heat welding, thereby forming the gusset cloths b 1 and b 2 as one body, and With the gusset fabrics b 1 and b 2 folded, insert both ends of the fabrics b 1 and b 2 between the side edges of the forming sheets a 1 and a 2 , and fold them together with the sheets a 1 and a 2 . It is heat welded to.
上記マチ部Ｂは上記の様な構成であるから復元
性（折られた状態に戻ろうとする性質）が良く、
エアーバツグＡを収縮させた際にはエアーバツグ
Ａ内へ確実に折り畳まれるものである。 Since the gusset part B has the above-mentioned configuration, it has good restorability (the ability to return to the folded state),
When the air bag A is deflated, it is folded into the air bag A reliably.
エアーバツグ本体Ａの対向面間に設ける吊り布
Ｃはマチ部Ｂと同様な構造であり、成形用シート

高さに保ち、エアーバツグＡの断面形状を任意の
形状、この場合略三角形状に保つ為のものであ
り、マチ布b1，b2も同様な働きをしている。 The hanging cloth C provided between the opposing surfaces of the air bag main body A has the same structure as the gusset part B, and is a molding sheet.
Heat weld the banding fabrics c 1 and c 2 to the inner surfaces of a 1 and a 2 parallel to the gusset fabrics b 1 and b 2 , fold them to the gusset fabrics b 1 and b 2 side, and heat the mating surfaces of their tips. Weld it. This hanging cloth C
When the air bag A is inflated, the distance between the forming sheets a 1 and a 2 at the hanging cloth C installation position is maintained at a predetermined height, and the cross-sectional shape of the air bag A is made into an arbitrary shape, in this case approximately triangular. The gusset cloth b 1 and b 2 have the same function.
そして、吊り布Ｃとマチ布b1，b2の接着部c3，
b3との間に両布ｃ，b1，b2間の間隔より幾分狭い

布b1，b2と吊り布Ｃとを連結する。（第２図）
次に、エアーバツグＡの作用を説明する。 And the adhesive part c 3 of the hanging cloth C and the gusset cloth b 1 , b 2 ,
An inversion prevention cloth d, which has a width slightly narrower than the distance between the two cloths c, b 1 and b 2 and is thinner than the forming sheets a 1 and a 2 , is installed between the molding sheets a 1 and a 2 . The anti-reversal cloth d has both edges glued together.
It is fixed by heat welding to c 3 and b 3 , and the gusset cloth b 1 and b 2 and the hanging cloth C are connected by the same cloth d. (Fig. 2) Next, the action of the air bag A will be explained.
収縮時、エアーバツグＡは第３図に示す様に、
マチ布b1，b2はエアーバツグＡ内へ、また吊り布
Ｃはマチ布b1，b2側へ折り畳まれると共に、反転
防止布ｄも断面型に折れ曲つている。 When deflated, air bag A is as shown in Figure 3.
The gusset fabrics b 1 and b 2 are folded into the air bag A, the hanging fabric C is folded towards the gusset fabrics b 1 and b 2 , and the anti-reversal fabric d is also folded into a cross-sectional shape.
給気口e1，e2から給気してエアーバツグ本体を
膨張させると、マチ布b1，b2が外方へ膨らむと同
時に、吊り布Ｃは両成形用シートa1，a2によつて
展開し、反転防止布ｄが張られる。 When air is supplied from the air supply ports e 1 and e 2 to inflate the air bag body, the gusset fabrics b 1 and b 2 expand outward, and at the same time, the hanging fabric C is expanded by both forming sheets a 1 and a 2 . It is unfolded and the reversal prevention cloth d is stretched.
そして、エアーバツグＡ内の圧力が高まると、
マチ布b1，b2は外部へ向けて反転しようとする
が、同布b1，b2の接着部b3が展開状態にある吊り
布Ｃに連結される反転防止シートｄによりエアー
バツグＡ内部側へ引かれることによつて、平面状
に展開した状態で保持される。 Then, when the pressure inside air bag A increases,
The gusset fabrics b 1 and b 2 try to flip outward, but the adhesive part b 3 of the fabrics b 1 and b 2 is inside the air bag A due to the flip prevention sheet d connected to the unfolded hanging fabric C. By being pulled to the side, it is held in a flat, unfolded state.
上記したエアーバツグＡは吊り布Ｃをマチ部Ｂ
と同様な構造にしたので、収縮時には確実に薄く
折り畳まれるものである。 For the air bag A mentioned above, the hanging cloth C is attached to the gusset part B.
Since it has a similar structure, it will surely fold thinly when deflated.
尚、前記した吊り布Ｃは、第４図に示す如くマ
チ布b1，b2を同じ方向へ向けて取付けても良く、
また、第６図に示す如く単なる一枚物、若しくは

る２辺に設けることも可能である。 Incidentally, the above-mentioned hanging cloth C may be attached with the gusset cloths b 1 and b 2 facing the same direction as shown in FIG.
Further, a simple hanging cloth C as shown in FIG. 6 or a pipe-shaped hanging cloth C as shown in FIG. 7 may be used. In addition, as mentioned above, each air bag has a gusset part only on one side of the air bag body, but if there is enough space inside the air bag body to install two or more sets of hanging cloth or inversion prevention sheets, the gusset part can be used. It is also possible to provide them on two or more sides of the air bag body, for example on two opposing sides of the air bag body.
