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ク 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。そして、このエアバッグ装置はその作動にあたり、電気信 号等によりインフレータから噴出された燃焼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。 An 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 the vehicle collides, and is usually a gas generator and an inflator. It is composed of a bag which is inflated by the gas of the inflator and an airbag case which encloses the inflator and the bag in a substantially airtight manner. When the airbag apparatus operates, the combustion gas ejected from the inflator by an electric signal or the like fills the airbag case and the airbag to generate an internal pressure, and the internal pressure causes the bag to expand.
【０００３】 一方、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 れており、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、実願平２−４０６９５４号にて本願出願人によって提案されて いる。即ち、このエアバッグは、Ｕ字状に折曲された本体布（１）と、この本体 布（１）の両側部に夫々縫着された２枚の側面布（２）によってバッグ本体が構 成されると共に、本体布（１）のＵ字状両先端部と各側面布（２）の先端部とに より開口部（３）が区画形成された構成を有している。そして、この開口部（３ ）には、上記各布先端部を夫々折り返し縫着することにより筒状のリテーナー取 付部（４）が設けられており、このリテーナー取付部（４）は、その内部に挿入 されるリテーナー（５）を介してエアバッグケース（図示せず）に取付けられる 。On the other hand, the above airbag device is not limited to the driver's seat, but a passenger's seat airbag device has been developed in recent years, and the airbag body of this passenger airbag device is as shown in FIG. A bag is proposed by the applicant in Japanese Patent Application No. 2-406954. That is, this airbag has a main body cloth (1) bent in a U shape and two side cloths (2) sewn on both sides of the main body cloth (1) to form a main body of the bag. The main body cloth (1) has a U-shaped front end portion and each side cloth (2) front end portion, so that an opening (3) is defined. The opening (3) is provided with a tubular retainer attaching portion (4) by folding back and sewing the respective cloth tip portions, and the retainer attaching portion (4) is It is attached to an airbag case (not shown) via a retainer (5) inserted inside.
【０００４】[0004]
ところで、図３に示す如く、上記リテーナー取付部（４）には、その外周に補 強布（７′）が重合されて、上記取付部（４）の筒軸方向に縫製を施すことによ って該取付部（４）基部に縫着されている。この補強布（７′）は、エアバッグ 装置の作動時に上記リテーナー取付部（４）の補強を図るものであるが、上記エ アバッグにおいては、この補強布の余端（９′）を長めに、かつ基布いっぱいに 幅広く形成し、エアバッグをケースに収納した際にこの余端（９′）でエアバッ グを包むことにより、エアバッグドアによるエアバッグの挟み込みや該ドアの表 面剤等によるエアバッグの変質を防止している。 By the way, as shown in FIG. 3, a reinforcing cloth (7 ') is superposed on the outer periphery of the retainer mounting portion (4), and sewing is performed in the cylinder axis direction of the mounting portion (4). Therefore, it is sewn to the base of the mounting portion (4). The reinforcing cloth (7 ') is intended to reinforce the retainer mounting portion (4) when the airbag device is in operation, but in the air bag, the extra end (9') of the reinforcing cloth is made longer. In addition, by forming a wide base cloth and wrapping the airbag at this extra end (9 ') when the airbag is stored in the case, the airbag can be pinched by the airbag door or the surface material of the door, etc. This prevents the deterioration of the airbag due to.
【０００５】 しかしながら、上記の如き補強布の構成であると、エアバッグ本体を作成する に際し、前記本体布と側面布とを縫着するときに上記補強布を巻き込んで縫製し てしまう可能性があり、この巻き込み縫製が誤ってなされた場合は、エアバッグ の展開時にバッグが正常に膨張できず、また、バッグの一部の縫製部に無理な力 が集中することから該縫製部からエアバッグが破損する恐れも招来する。However, with the structure of the reinforcing cloth as described above, there is a possibility that the reinforcing cloth may be caught and sewn when the body cloth and the side cloth are sewn together when the airbag body is created. If the sewn-in stitch is mistakenly performed, the bag cannot be inflated normally when the airbag is deployed, and unreasonable force is concentrated on a part of the sewn part of the bag, so that the airbag is sewn from the sewn part. There is also a risk of damage.
【０００６】 本考案は、叙上の如き実状に対処し、上記補強布に新規な構成を見出すことに より、本体布と側面布の縫着時における補強布の巻き込み縫製の防止を図り、も ってエアバッグの正常な展開を確実に行わしめることを目的とするものである。The present invention copes with the actual situation as described above, and by discovering a new structure for the above-mentioned reinforcing cloth, it is possible to prevent winding of the reinforcing cloth when sewing the main body cloth and the side cloth. Therefore, the purpose is to ensure the normal deployment of the airbag.
【０００７】[0007]
即ち、上記目的に適合する本考案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した１対の側面布とでエアバッグを構成し、 該エアバッグ開口部の上記各基布の端部に補強布を重合せしめると共に、これら 基布と補強布とを折り返し縫着して筒状のリテーナー取付部を形成せしめたエア バッグにおいて、上記補強布を、上記本体布両側と各側面布との縫製部から、所 定幅内側に寄せて幅狭く形成せしめたところにある。 That is, the feature of the airbag of the present invention which meets the above-mentioned purpose is that the airbag is composed of a body cloth bent in a U shape and a pair of side cloths sewn on both sides of the body cloth. In the airbag, the reinforcing cloth is superposed on the end portions of the base cloths of the airbag opening, and the base cloth and the reinforcing cloth are sewn back to form a tubular retainer mounting portion. The cloth is formed by narrowing the cloth from the sewn portions on both sides of the main body cloth and the side cloths to the inner side of the predetermined width.

以下、さらに添付図面を参照して、本考案の実施例を説明する。 図１は本考案実施例のエアバッグを示す斜視図、図２は図１のＡ−Ａ線断面図 であり、このエアバッグは図１に示す如く、Ｕ字状に折曲した本体布（１）と、 この本体布（１）の両側部に夫々縫着せしめた１対の側面布（２）によってバッ グ本体を構成すると共に、上記本体布（１）のＵ字状両先端部と各側面布（２） の先端部とによって開口部（３）を区画形成せしめた基本的構成を有している。 また、同図に示すように、上記開口部（３）には、上記各布先端部を夫々折り返 し縫着することにより筒状のリテーナー取付部（４）が設けられており、このリ テーナー取付部（４）は、その内部に挿入されるリテーナーを介してエアバッグ ケース（共に図示せず）に取着される。なお、図において（６）はリテーナーの ボルト挿通孔である。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an airbag according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line AA of FIG. 1. As shown in FIG. 1) and a pair of side cloths (2) sewn on both sides of the main body cloth (1) to form a bag main body, and the U-shaped front end portions of the main body cloth (1). It has a basic structure in which the opening (3) is defined by the tip of each side cloth (2). Further, as shown in the figure, the opening (3) is provided with a tubular retainer attaching portion (4) by folding back and sewing the respective cloth tip portions. The retainer mounting portion (4) is attached to an airbag case (both not shown) via a retainer inserted therein. In the figure, (6) is a bolt insertion hole of the retainer.
【００１０】 一方、図１及び図２に示すように、上記リテーナー取付部（４）には、その外 周に補強布（７）が重合されており、該補強布（７）は、上記取付部（４）の筒 軸方向に２本の縫製（８）を施すことによって該取付部（４）基部に縫着されて いる。上記補強布（７）としては、エアバッグをケースにコンパクトに折り畳む ためや、エアバッグ装置のコストダウンならびに軽量化等のためにノンコート布 が使用され（一部、本体布の上側のリテーナー取付部には、コーティングした補 強布を用いこともある）、さらに、強度確保のために、エアバッグの展開方向に 対して織目をバイアスに設定して重合されている。また、上記補強布（７）は、 上記縫着部（８）からエアバッグの表面に沿って、余端（９）を形成せしめてい る。 そして、本考案では、上記の如く構成したエアバッグにおいて、図１，図 ２に示す如く、上記補強布（７）を、上記本体布（１）両側と各側面布（２）と の縫製部（１０）から、所定幅（Ｌ）だけ内側に寄せて幅狭く形成せしめた構成 を採用している。即ち、図１に示す如く、この実施例では補強布（７）の両側を 、各補強布（７）が重合された各基布（１），（２）の両側から夫々５〜１５ｍ ｍ程度内側に寄せて該補強布（７）を各々幅狭に形成せしめている。On the other hand, as shown in FIGS. 1 and 2, a reinforcing cloth (7) is superposed on the outer periphery of the retainer mounting part (4), and the reinforcing cloth (7) is attached to the mounting part (4). The part (4) is sewn to the base of the mounting part (4) by sewing two pieces (8) in the cylinder axial direction. As the reinforcing cloth (7), non-coated cloth is used for compactly folding the airbag in the case, and for cost reduction and weight reduction of the airbag device (partly, the retainer mounting portion on the upper side of the body cloth). In some cases, a coated reinforcing cloth is used), and in order to secure the strength, the weave is set to a bias in the direction of deployment of the airbag and polymerized. Further, the reinforcing cloth (7) has a surplus end (9) formed along the surface of the airbag from the sewn portion (8). In the present invention, in the airbag constructed as described above, as shown in FIGS. 1 and 2, the reinforcing cloth (7) is sewn to both sides of the body cloth (1) and the side cloths (2). From (10), a configuration is adopted in which a predetermined width (L) is brought inward to form a narrow width. That is, as shown in FIG. 1, in this embodiment, both sides of the reinforcing cloth (7) are about 5 to 15 mm from both sides of the respective base cloths (1) and (2) on which the reinforcing cloth (7) is polymerized. The reinforcing cloths (7) are formed to be narrower toward each other.
【００１１】 また、上記補強布（７）は、上記の如く幅狭に形成するが、図１の如く全ての 部分を幅狭に形成する必要はなく、例えば、リテーナー取付部（４）としての筒 状の部分においては通常の幅に形成することも可能である。即ち、補強布（７） の前記余端（９）のみを幅狭に形成するだけでも、所期の目的は達成しうるもの であり、さらに、例えばこの余端（９）を先端に行くに従い細くなるテーパ状と し、先端の角部を内側に寄せると共に、その角を鈍角として、エアバッグ展開時 の衝撃による該角部のほつれを防止することも可能である。Further, although the reinforcing cloth (7) is formed with a narrow width as described above, it is not necessary to form all the parts with a narrow width as shown in FIG. 1, and for example, as the retainer mounting portion (4). The tubular portion can be formed to have a normal width. That is, the intended purpose can be achieved even by forming only the extra edge (9) of the reinforcing cloth (7) narrowly. Further, for example, as the extra edge (9) goes to the tip, It is also possible to taper the taper so that the corners of the tips are brought inward and the corners are made obtuse to prevent the corners from fraying due to impact when the airbag is deployed.
【００１２】 しかして、上記構成を有する本考案実施例のエアバッグにおいては、エアバッ グ本体布（１）と側面布（２）との縫製部（１０）から、所定幅内側に寄せて幅 狭く補強布（７）を形成してなることから、該補強布（７）が上記本体布（１） と側面布（２）の縫着に巻き込まれることなはく、これによって、上記本体布（ １）と側面布（２）との縫製が手際よくミシン等で自動化して迅速に行えるよう になり、さらにエアバッグ作成後には、該エアバッグの正常な展開が確保される 。However, in the airbag of the embodiment of the present invention having the above-described structure, the airbag body cloth (1) and the side cloth (2) are sewn toward the inside by a predetermined width from the sewn portion (10) and narrowed. Since the reinforcing cloth (7) is formed, the reinforcing cloth (7) is not caught in the sewing of the main body cloth (1) and the side cloth (2), whereby the main body cloth (7) is The sewing of 1) and the side cloth (2) can be done quickly and automatically by a sewing machine, etc., and the normal deployment of the airbag is ensured after the airbag is created.
