【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial application]

本考案は車両に装備し、車両の衝突事故の際に自動的に膨張し、乗員を保護す るエアバッグ装置に係り、詳しくはエアバッグ装置のエアバッグ本体に関するも のである。 The present invention relates to an airbag device that is installed in a vehicle and automatically inflates in the event of a vehicle collision and protects an occupant, and more particularly to an airbag body of the airbag device.

【0002】[0002]

【従来の技術】[Prior Art]

エアバッグ装置は、車両が衝突した時、衝撃が所定以上である場合にシートベ ルトの補助として瞬時にバッグが膨張し、乗員を保護する安全装置であり、通常 、ガス発生器であるインフレータと、インフレータのガスにより膨張するバッグ と、前記インフレータを該バッグと共に略気密に囲繞収納するエアバッグケース とで構成されている。 The airbag device is a safety device that protects an occupant by inflating the bag instantaneously as an aid to the seat belt when the impact is more than a predetermined value when a vehicle collides, and is usually a gas generator and an inflator. It is composed of a bag that is inflated by the gas of the inflator and an airbag case that encloses the inflator together with the bag in a substantially airtight manner.

【0003】 そして、このエアバッグ装置はその作動にあたり、インフレータから噴出され たガスがエアバッグケースとエアバッグ内に充満して内圧を発し、この内圧によ りバッグが展開する。When the airbag apparatus operates, the gas ejected from the inflator fills the airbag case and the airbag to generate an internal pressure, and the internal pressure causes the bag to expand.

【0004】 ところで、上記エアバッグ装置は運転席用に限らず、近年助手席用のものも開 発されている。この助手席用エアバッグ装置のエアバッグ本体としては、図4に 示すようなバッグが従来使用されており、該バッグは、円筒状に縫製された本体 布(1)と該本体布(1)の両側面に夫々縫着された側面布(2)とによって構 成され、上記円筒状本体布(1)周面の一部に方形の開口部(3)が設けられて 前記インフレーターのガス流入口となっている。そして、この開口部(3)には 本体布(1)とは別布からなる4枚のリテーナー取付部(4),(5)が袋状を なすよう本体布(1)に縫着されており、該リテーナー取付部(4),(5)は その内部に挿入されるリテーナー(図示せず)を介して前記エアバッグケースに 装着される。By the way, the airbag device is not limited to the driver's seat, but a passenger's seat device has been developed in recent years. A bag as shown in FIG. 4 is conventionally used as an airbag body of the passenger side airbag device. The bag is a body cloth (1) sewn in a cylindrical shape and the body cloth (1). Side surface cloth (2) sewn on both side surfaces of the cylindrical body cloth (1), and a rectangular opening (3) is provided in a part of the peripheral surface of the cylindrical main body cloth (1). It is the entrance. Then, in the opening (3), four retainer mounting portions (4), (5) made of a cloth different from the body cloth (1) are sewn to the body cloth (1) so as to form a bag shape. The retainer mounting portions (4) and (5) are attached to the airbag case via a retainer (not shown) inserted therein.

【0005】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上記従来のエアバッグは取付部が本体布と別体であり、それを 本体布に重ねて縫着することから、本体布の取付部縫着部の厚みが大きくなり、 折畳み収納時のバッグ収納容積が大きくなるという欠点を有している。 また、エアバッグ装置を取付ける車両の種類によっては、図3に示すようにバ ッグの上下の取付部(4)を前後方向にずらせてエアバッグケース(9)に装着 することが考えられるが、上記従来のエアバッグでは、本体布周面が邪魔になっ て図5に示す如くまっ直にしか装着することができないという不都合も有してい る。 However, since the attachment part of the conventional airbag described above is separate from the body cloth and is overlaid and sewn on the body cloth, the thickness of the attachment part of the body cloth at the attachment part becomes large, and the airbag is not easily stored when folded and stored. It has a drawback that the bag storage capacity becomes large. Also, depending on the type of vehicle to which the airbag device is mounted, it is conceivable that the upper and lower mounting portions (4) of the bag are displaced in the front-rear direction as shown in FIG. 3 to be mounted on the airbag case (9). However, the above-mentioned conventional airbag also has the disadvantage that it can be mounted only straight as shown in FIG.

【0006】 本考案は叙上の如き実情に対処し、エアバッグ本体に新規な構造を見出すこと により、折畳み収納時のエアバッグの収納容積を小さくし、さらにエアバッグケ ースに対するバッグの装着性ならびにリテーナー取付部の強度の向上をはかるこ とを目的とするものである。The present invention copes with the above-mentioned circumstances, and by finding a new structure in the airbag body, the storage volume of the airbag when folded and stored is reduced, and further, the mounting property of the bag to the airbag case and The purpose is to improve the strength of the retainer mounting part.

【0007】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

即ち、上記目的に適合する本考案車両用エアバッグの特徴は、U字状に折曲し た本体布と、該本体布の両側部に夫々縫着された側面布とによってバッグ本体を 構成し、上記本体布のU字の両先端部と各側面布の先端部とにより開口部を区画 形成すると共に、それら各先端部を独立に折り返し縫着して袋状のリテーナー取 付部を形成し、かつ、これら各リテーナー取付部に補強布を、バッグの展開方向 に対し、その経・緯糸を斜行せしめて重合縫着したところにある。 That is, the feature of the vehicle airbag of the present invention which meets the above-mentioned purpose is that the body of the bag is composed of a U-shaped body cloth and side cloths sewn on both sides of the body cloth. An opening is defined by the U-shaped tip portions of the main body cloth and the tip portions of the side surface cloths, and the tip portions are independently folded and sewn to form a bag-shaped retainer attaching portion. In addition, the reinforcing cloth is attached to each of the retainer mounting portions, and the warps and wefts of the reinforcing cloth are slanted with respect to the deployment direction of the bag and overlapped and sewn.

【0008】[0008]

【作用】[Action]

上記構成を有する本考案のエアバッグは、リテーナー取付部が夫々、本体布の 両先端部あるいは各側面布の先端部を折り返すことにより形成されているため、 従来の別布を2つ折りにして本体布に縫着するものより縫着部を薄くすることが でき、エアバッグの折畳み収納容積を小さくすることができる。 In the airbag of the present invention having the above structure, since the retainer mounting portion is formed by folding back both ends of the main body cloth or the front end of each side cloth, the conventional separate cloth is folded in two and the main body is folded. The sewn portion can be made thinner than that sewn on cloth, and the folding storage capacity of the airbag can be reduced.

【0009】 また、上記リテーナー取付部は夫々、本体布あるいは側面布の延長上に位置す ることから、従来のバッグのように本体布周面が邪魔になることもなく、図3に 示すようにバッグの上下の取付部を前後方向にずらせてエアバッグケースに装着 することが可能となる。 そして、さらに本考案エアバッグのリテーナー取付部は、補強布をバッグの展 開方向に対し、経・緯糸が斜交するよう縫着してなることから、織糸の一方を上 記展開方向に直行させるように配位した一般のものに比し、該リテーナー取付部 の強度を大きく向上させることが可能となる。Further, since the retainer mounting portions are respectively located on the extensions of the main body cloth or the side cloth, the peripheral surface of the main body cloth does not get in the way as in a conventional bag, as shown in FIG. The upper and lower mounting parts of the bag can be displaced in the front-rear direction and mounted on the airbag case. Further, since the retainer attaching portion of the airbag of the present invention is sewn with the reinforcing cloth so that the warp and the weft threads are obliquely crossed with respect to the expanding direction of the bag, one of the weaving threads is arranged in the expanding direction. It is possible to greatly improve the strength of the retainer mounting portion, as compared with a general type in which the retainer mounting portion is arranged so as to go straight.

The warp thread (10) and the weft thread (11) are overlapped and sewn with each being obliquely crossed at 45 degrees. This reinforcing cloth (6) greatly enhances the strength of the retainer mounting portions (4) and (5) by orienting the weaving yarns obliquely as described above, and the opening portion is made of coated silicone rubber. The heat resistance of (3) is improved. In addition, as shown in FIG. 1, the reinforcing cloth (6) folded back over the main body cloth (1) at the upper and lower retainer mounting portions (4) has ear portions (6a) extending laterally, respectively. The ear portion (6a) is sewn so as to overlap with the folded pieces (5a) of the left and right retainer mounting portions (5) to improve the pressure resistance.

【0014】 以上の構成を有する本考案のエアバッグは、図1に示す、断面コの字形のボル ト付リテーナー(7)を各取付部(4),(5)内に挿入し、取付部のボルト孔 (8)からリテーナー(7)のボルトを通して、例えば図3のようにエアバッグ ケース(9)に装着する。この際、同図に示す如く、上下のリテーナー取付部(4 )の取付位置が前後にずれているような場合でも、本考案エアバッグはリテーナ ー取付部(4),(5)が夫々、本体布(1)あるいは側面布(2)の延長上に 位置することから、上記取付位置(取付面角度θ)に対し充分に対応することが 可能である。In the airbag of the present invention having the above-described structure, the retainer (7) with a bolt having a U-shaped cross section shown in FIG. 1 is inserted into each of the mounting portions (4) and (5), and the mounting portion is attached.
