まず、予め折り畳まれたエアバッグ２及びガーニッシュ18を、取付部材27に取り付ける。この作業は、取付部材27の支持部63の車室４側の面に、エアバッグ２の取付片部32とガーニッシュ18のガーニッシュ取付片部43とを重ね、これら取付片部32とガーニッシュ取付片部43との取付孔32a，45を互いに位置合わせして、これら取付孔32a，45に挿入した取付具68を支持部63の取付孔66に固定することにより完了する。すなわち、この状態で、エアバッグ２、ガーニッシュ18、及び取付部材27が互いに組み合わされたユニットが構成される。また、この状態で、ガーニッシュ18のガーニッシュ本体部41の外面すなわち車室４から見た背面側に沿って、エアバッグ２が保持される。 First, the airbag 2 and the garnish 18 folded in advance are attached to the attachment member 27. In this work, the mounting piece portion 32 of the airbag 2 and the garnish mounting piece portion 43 of the garnish 18 are overlapped on the surface of the support portion 63 of the mounting member 27 on the side of the passenger compartment 4, and the mounting piece portion 32 and the garnish mounting piece. The mounting holes 32a and 45 with the portion 43 are aligned with each other, and the mounting tool 68 inserted into the mounting holes 32a and 45 is fixed to the mounting hole 66 of the support portion 63. That is, in this state, a unit in which the airbag 2, the garnish 18, and the attachment member 27 are combined with each other is configured. Further, in this state, the airbag 2 is held along the outer surface of the garnish main body 41 of the garnish 18, that is, along the back side as viewed from the passenger compartment 4.

また、ブラケット26は、図示しないビスあるいはリベットなどの固着具を固定孔58に挿入して車体パネル15に固定するなどして、予め車体３に取り付けておく。 The bracket 26 is attached to the vehicle body 3 in advance by inserting a fixing tool such as a screw or rivet (not shown) into the fixing hole 58 and fixing it to the vehicle body panel 15.

次いで、エアバッグ２、ガーニッシュ18、及び取付部材27を互いに組み合わせたユニットを、ブラケット26に取り付ける。この作業は、取付部材27の各取付部69を、それぞれブラケット26の各取付受部54に圧入して係合することにより完了する。すなわち、図１に示すように、取付部材27の取付部69の軸部62aを、上方から、取付受部54の挿入部54bを介して保持受部54aに圧入する。軸部62aは、上側すなわち縁部から下側すなわち保持受部54a側に向かって幅寸法が小さくなる挿入部54bに案内され、円滑に挿入されるとともに、保持受部54aに挿入された状態では、挿入部54bの幅寸法の小さい部分に係合して抜け止めされる。さらに、この状態で、ブラケット26の保持受部54aの周辺の部分が、取付部69の取付部基板部65と組付ピン62の頭部62bとの間に挟持され、強固に固定されるようになっている。 Next, a unit in which the airbag 2, the garnish 18, and the attachment member 27 are combined with each other is attached to the bracket 26. This operation is completed by press-fitting and engaging each attachment portion 69 of the attachment member 27 with each attachment receiving portion 54 of the bracket 26, respectively. That is, as shown in FIG. 1, the shaft portion 62a of the mounting portion 69 of the mounting member 27 is press-fitted into the holding receiving portion 54a from above via the insertion portion 54b of the mounting receiving portion 54. The shaft portion 62a is guided by the insertion portion 54b whose width dimension is reduced from the upper side, that is, the edge portion, to the lower side, that is, the holding receiving portion 54a, and is smoothly inserted and inserted in the holding receiving portion 54a. The insertion portion 54b is engaged with a portion having a small width and is prevented from coming off. Further, in this state, the peripheral portion of the holding receiving portion 54a of the bracket 26 is sandwiched between the mounting portion substrate portion 65 of the mounting portion 69 and the head portion 62b of the assembly pin 62 so as to be firmly fixed. It has become.

そして、このユニットのブラケット26への取付作業の前後いずれかに、インフレータ25の接続管25bをエアバッグ２に接続するとともに、インフレータ25を車体３側に備えた制御装置に電気的に接続することにより、エアバッグ装置１の車体３への取付作業が完了する。 Then, before or after the operation of attaching the unit to the bracket 26, the connecting pipe 25b of the inflator 25 is connected to the airbag 2, and the inflator 25 is electrically connected to a control device provided on the vehicle body 3 side. As a result, the operation of attaching the airbag device 1 to the vehicle body 3 is completed.

なお、このエアバッグ装置１及びヘッドライニング16を車体３へ取り付けた状態では、ガーニッシュ18のガーニッシュ側取付部42は、ヘッドライニング16により覆われて車室４側に露出しないとともに、ヘッドライニング16の面とガーニッシュ本体部41の面とがほぼ面一に連続するようになっている。 When the airbag device 1 and the head lining 16 are attached to the vehicle body 3, the garnish side attachment portion 42 of the garnish 18 is covered with the head lining 16 and is not exposed to the vehicle compartment 4 side. The surface and the surface of the garnish main body portion 41 are substantially flush with each other.

次に、エアバッグ２の展開動作を説明する。 Next, the deployment operation of the airbag 2 will be described.

車両の側面衝突あるいは横転などの際には、制御装置によりインフレータ25が作動し、このインフレータ25から噴射されるガスが接続管25bを介しガス導入口からエアバッグ本体部31内の膨張部に導入される。すると、エアバッグ本体部31の膨張部は、図７及び図８に示すように、ガーニッシュ18を押しのけながら膨張展開し、所定面14に沿った所定方向である略下方に迅速にカーテン状に膨張展開して、窓部及びセンターピラーなどを覆い、乗員とセンターピラーなどとの衝突の衝撃を緩和するとともに、乗員の車外放出を防止して保護する。 In the event of a side collision or rollover of the vehicle, the inflator 25 is activated by the control device, and the gas injected from the inflator 25 is introduced into the inflating portion in the airbag main body 31 from the gas inlet through the connecting pipe 25b. Is done. Then, as shown in FIGS. 7 and 8, the inflating portion of the airbag main body 31 inflates and deploys while pushing away the garnish 18, and quickly inflates substantially downward in a predetermined direction along the predetermined surface 14. Deploy and cover the window and center pillar, etc. to reduce the impact of collision between the occupant and the center pillar, and to prevent and protect the occupant from being released from the vehicle.

このエアバッグ２の膨張展開の際、樹脂製のガーニッシュ18が弾性的に変形するとともに、取付部材27の鉄板製の連結部64が塑性変形してガーニッシュ18を移動させ、エアバッグ２を円滑に展開させる。 When the airbag 2 is inflated and deployed, the resin garnish 18 is elastically deformed and the iron plate connecting portion 64 of the mounting member 27 is plastically deformed to move the garnish 18 so that the airbag 2 can be smoothly moved. Expand.

このように、本実施の形態によれば、いわばエアバッグモジュールとルーフサイドガーニッシュを一体化し、細長く折り畳まれた状態からガスが導入されて膨張展開する長尺なエアバッグ２と、このエアバッグ２を長手方向に沿って覆う内装材であるガーニッシュ18とを備えたカーテンエアバッグであって、これらエアバッグ２、ガーニッシュ18、及び取付部材27を一体的に組み合わせてモジュールを構成し、これらエアバッグ２とガーニッシュ18とを支持する取付部材27の取付部69を、車体３に固定したブラケット26の取付受部54に係合し、いわばワンタッチで取り付けできるため、細長く折り畳んだ長尺なエアバッグ２を備えたエアバッグ装置１の車両への組み付け作業性を向上して設置作業を容易にでき、作業時間を短縮し、あるいはロボットを用いた作業が可能になり、エアバッグ装置１の車体３への取付作業のコストを低減できる。 As described above, according to the present embodiment, the airbag module and the roof side garnish are integrated, and the long airbag 2 that is inflated and deployed by introducing gas from the state of being elongated and folded, and the airbag 2. A curtain airbag including an interior material garnish 18 that covers the interior of the airbag along the longitudinal direction, and the airbag 2, the garnish 18, and the mounting member 27 are integrally combined to form a module. Since the attachment portion 69 of the attachment member 27 that supports the garnish 18 and the garnish 18 is engaged with the attachment receiving portion 54 of the bracket 26 fixed to the vehicle body 3, so that it can be attached with one touch, the elongated airbag 2 that is folded into an elongated shape Assembling workability of the airbag apparatus 1 equipped with the vehicle to the vehicle can be improved, and the installation work can be facilitated. Thus, the work of attaching the airbag device 1 to the vehicle body 3 can be reduced.

また、取付部材27の取付部69をブラケット26の取付受部54に係合する作業は、上側から引っ掛ける作業であり、作業性が良いとともに、エアバッグ２の展開時に展開方向である下方に向かう力に対して、エアバッグ２を強固に保持できる。 Further, the operation of engaging the attachment portion 69 of the attachment member 27 with the attachment receiving portion 54 of the bracket 26 is an operation for hooking from the upper side, and the workability is good, and the downward direction which is the deployment direction when the airbag 2 is deployed. The airbag 2 can be firmly held against the force.

また、取付部材27には、ガーニッシュ18を支持する支持部63と、ブラケット26を介して車体３側に固定される取付部69を設けるとともに、これら支持部63と取付部69とを塑性変形可能な金属製の連結部64を介して連結し、すなわち、車体３側に対して塑性変形可能な金属製の連結部64を介してガーニッシュ18を支持したため、エアバッグ２の展開時に、エアバッグ２がガーニッシュ18を押動すると、連結部64が塑性変形して、ガーニッシュ18が開く方向の移動を許容し、エアバッグ２を円滑に展開できる。ここで、取付部材27の連結部64は、塑性変形可能な金属製としたため、樹脂製の構成に比べて、温度変化に伴う特性の変化が小さく、すなわち、高温時にも軟化せずにヒンジ機能を維持でき、通常時にはガーニッシュ18がエアバッグ２を外観良く安定して覆うとともにエアバッグ２の展開時にはガーニッシュ18が適切な速度で適切な寸法だけ移動する好ましい特性が容易に実現される。 The mounting member 27 is provided with a support portion 63 that supports the garnish 18, and a mounting portion 69 that is fixed to the vehicle body 3 via the bracket 26, and the support portion 63 and the mounting portion 69 can be plastically deformed. Since the garnish 18 is supported via the metallic connecting portion 64, that is, the metallic connecting portion 64 that is plastically deformable with respect to the vehicle body 3 side, the airbag 2 is deployed when the airbag 2 is deployed. When the garnish 18 is pushed, the connecting portion 64 is plastically deformed, allowing movement in the direction in which the garnish 18 is opened, and the airbag 2 can be deployed smoothly. Here, since the connecting portion 64 of the mounting member 27 is made of a plastically deformable metal, the change in characteristics due to a temperature change is small compared to the resin configuration, that is, the hinge function without being softened even at high temperatures. In the normal state, the garnish 18 covers the airbag 2 with a good appearance and stability, and at the same time, when the airbag 2 is deployed, a desirable characteristic that the garnish 18 moves by an appropriate dimension at an appropriate speed is easily realized.

そして、ガーニッシュ18を支持する支持部63は、ガーニッシュ18の長手方向に沿って配置されるとともに、連結部64は、取付部材27を構成する取付部材本体部61の支持部63と取付部基板部65とに一体に連続して形成されたため、簡略な構成で、通常時にはガーニッシュ18がエアバッグ２を外観良く安定して覆うとともにエアバッグ２の展開時にはガーニッシュ18が円滑に移動する好ましい特性を容易に実現できる。さらに、連結部64は、支持部63から複数突設したため、連結部64の幅寸法の設定などによりガーニッシュ18の挙動の調整も容易であり、エアバッグ装置１の製造コストを低減できる。 The support portion 63 that supports the garnish 18 is disposed along the longitudinal direction of the garnish 18, and the connection portion 64 includes the support portion 63 of the attachment member main body portion 61 that constitutes the attachment member 27, and the attachment portion substrate portion. Since the garnish 18 has a simple structure, the garnish 18 normally covers the airbag 2 with good appearance and stability, and the garnish 18 moves smoothly when the airbag 2 is deployed. Can be realized. Furthermore, since a plurality of connecting portions 64 are provided so as to protrude from the support portion 63, the behavior of the garnish 18 can be easily adjusted by setting the width dimension of the connecting portion 64, and the manufacturing cost of the airbag device 1 can be reduced.

また、ガーニッシュ18は、樹脂にて形成したため、鉄板などで形成する構成に比べ、内装材として適した外観や衝撃吸収特性などの特性を容易に実現できる。そして、塑性変形可能な金属製の複数の連結部64で、軽量で弾性変形する樹脂製のガーニッシュ18を支持することにより、ガーニッシュ18を長手方向に沿って均一に展開させ、すなわち、各部位での展開の時間差を小さくすることができる。 Further, since the garnish 18 is formed of resin, characteristics such as appearance and shock absorption characteristics suitable as an interior material can be easily realized as compared with a structure formed of an iron plate or the like. Then, by supporting the resin garnish 18 that is light and elastically deformed with a plurality of plastically deformable metal connecting portions 64, the garnish 18 is uniformly deployed along the longitudinal direction, that is, at each part. It is possible to reduce the time difference of development of

さらに、取付部材27は、取付部材本体部61の取付部基板部65に組付ピン62を取り付けて容易に形成できる。そして、取付部69は、板状の取付部基板部65に組付ピン62を貫通し固定して取り付けることにより、取付部基板部65と組付ピン62の頭部62bとの間に、ブラケット26を挟持して強固に係合保持する構成を容易に実現できるとともに、組付ピン62の先端部62cを取付部材27の支持部63に対向させ、さらに、組付ピン62の先端部62cを支持部63に当接させることにより、簡略な構成で、取付部69が支持部63側に変形することを防止し、すなわちヒンジの内倒れを防止して、取付部材27の形状を安定して維持できるとともに、がたつきを防止できる。 Further, the attachment member 27 can be easily formed by attaching the assembly pin 62 to the attachment portion substrate portion 65 of the attachment member main body portion 61. Then, the mounting portion 69 is attached to the plate-shaped mounting portion substrate portion 65 through the fixing pin 62 so as to be fixed between the mounting portion substrate portion 65 and the head portion 62b of the mounting pin 62. 26 can be easily realized, and the front end portion 62c of the assembly pin 62 is opposed to the support portion 63 of the mounting member 27, and the front end portion 62c of the assembly pin 62 is further fixed. By contacting the support portion 63, the mounting portion 69 can be prevented from being deformed to the support portion 63 side with a simple configuration, that is, the hinge can be prevented from falling down, and the shape of the mounting member 27 can be stabilized. It can be maintained and can prevent rattling.

このようにして、細長く折り畳んだ長尺なエアバッグ２を備えるとともに、このエアバッグ２を内装材であるガーニッシュ18で覆ったカーテンエアバッグについて、製造コストを低減できるとともに、展開特性を容易に良好にできる。 In this way, the curtain airbag having the long airbag 2 that is folded into a long and thin shape and covered with the garnish 18 that is the interior material can reduce the manufacturing cost and easily has good deployment characteristics. Can be.

なお、上記の実施の形態では、取付部材27について、組付ピン62の先端部62cを支持部63に当接させたが、僅かな間隔を介して対向させることもできる。また、取付部材27の支持部63の各取付孔66に取り付けた取付具68の先端部を、ブラケット26のブラケット本体部51に接離可能に当接することにより、取付部69が支持部63側に変形することを防止し、すなわちヒンジの内倒れを防止して、取付部材27の形状を安定して維持することもできる。 In the above-described embodiment, the tip end portion 62c of the assembly pin 62 is brought into contact with the support portion 63 in the mounting member 27, but may be opposed to the mounting member 27 with a slight interval. Further, by attaching the tip of the attachment 68 attached to each attachment hole 66 of the support portion 63 of the attachment member 27 to the bracket body portion 51 of the bracket 26 so as to be able to contact and separate, the attachment portion 69 is moved to the support portion 63 side. It is possible to prevent the hinge member from being deformed, that is, to prevent the hinge from falling down and to maintain the shape of the mounting member 27 stably.

また、ブラケット26の取付受部54は、図１に示す縁部に連続する溝状に限られず、組付ピン62の頭部62bを挿入可能な径寸法の孔状の挿入部と、この挿入部の下方に連続する溝状の保持受部とで、取付受部を形成することもできる。 Further, the mounting receiving portion 54 of the bracket 26 is not limited to the groove shape continuing to the edge portion shown in FIG. 1, but a hole-shaped insertion portion having a diameter dimension into which the head portion 62b of the assembly pin 62 can be inserted, and this insertion The attachment receiving portion can be formed by a groove-shaped holding receiving portion continuous below the portion.

また、上記の実施の形態では、ガーニッシュ18は、全長にわたり一体に形成したが、長手方向などに分割して形成することもできる。 In the above embodiment, the garnish 18 is integrally formed over the entire length, but may be formed by being divided in the longitudinal direction or the like.

一方、上記の実施の形態では、それぞれ複数の取付部材27及びブラケット26を用い、いわば長手方向に分割した構成としたが、これら取付部材27及びブラケット26について、長手方向に連続した構成とすることもできる。 On the other hand, in the above-described embodiment, a plurality of mounting members 27 and brackets 26 are used, and the configuration is divided in the longitudinal direction, so that the mounting members 27 and the brackets 26 are configured to be continuous in the longitudinal direction.
