従来、エアバッグを折り畳んで、ケースに収納させて車両に搭載させる構成の頭部保護エアバッグ装置としては、エアバッグを折り畳んで形成した折り完了体を、周囲に、折り崩れを防止して折り畳み状態を維持可能なテープ材を巻き付けた状態で、ケース内に収納させる構成のものがあった（例えば、特許文献１参照）。このテープ材は、エアバッグの膨張時に破断可能に形成されていた。   Conventionally, as a head protection airbag device having a configuration in which an airbag is folded and stored in a case and mounted on a vehicle, a folded body formed by folding the airbag is folded around the periphery to prevent collapse. There has been a configuration in which a tape material capable of maintaining the state is wound and accommodated in a case (see, for example, Patent Document 1). This tape material was formed so that it could be broken when the airbag was inflated.

また、エアバッグを折り畳んで、ケースに収納させて車両に搭載させる構成の頭部保護エアバッグ装置としては、エアバッグを折り畳んで形成した折り完了体をケースに収納させ、ケースと折り完了体との周囲に、エアバッグの膨張時に破断可能なテープ材を巻き付けて、折り完了体のケース内への収納状態を維持させる構成のものもあった（例えば、特許文献２参照）。   Further, as a head protection airbag device configured to fold an airbag and store it in a case and mount it on a vehicle, a folding completion body formed by folding the airbag is stored in the case, and the case and the folding completion body There is a configuration in which a tape material that can be broken when the airbag is inflated is wound around the bag to maintain the folded state of the folded body in the case (see, for example, Patent Document 2).

特開２００８−１８４０５６公報（図３）JP 2008-184056 A (FIG. 3) 特開２０１１−６８２７６公報（図４）Japanese Patent Laying-Open No. 2011-68276 (FIG. 4)

At the same time, the airbag assembly AM <b> 1 can be assembled to the vehicle V by fixing the mounting bracket 13 of the inflator 12 to a predetermined position of the inner panel 2 using the bolts 14. Thereafter, lead wires (not shown) extending from the control device for operating the inflator are connected to the inflator 12, and the front pillar garnish 5, the roof head lining 6, the intermediate pillar garnish 7, and the rear pillar garnish 8 are connected to the inner panel 2 on the body 1 side. The head protection airbag device M can be mounted on the vehicle V.

頭部保護エアバッグ装置Ｍの車両Ｖへの搭載後、制御装置からの作動信号を受けてインフレーター１２が作動されれば、インフレーター１２から吐出される膨張用ガスがエアバッグ２２内に流入して、膨張するエアバッグ２２が、締結バンド５７における係合突起６０と係合凹部６８との係合状態（締結バンド５７の締結状態）を解除しつつ、エアバッグカバー１０を押し開いて、下方へ突出しつつ展開し、図１の二点鎖線に示すように、窓Ｗ１，Ｗ２や中間ピラー部ＣＰ及びリヤピラー部ＲＰの車内側を覆うように、膨張を完了させることとなる。   After the head protection airbag device M is mounted on the vehicle V, the inflation gas discharged from the inflator 12 flows into the airbag 22 when the inflator 12 is activated in response to an operation signal from the control device. The inflating airbag 22 pushes the airbag cover 10 downward while releasing the engagement state between the engagement protrusion 60 and the engagement recess 68 in the fastening band 57 (fastening state of the fastening band 57), and moves downward. As shown by the two-dot chain line in FIG. 1, the expansion is completed so as to cover the windows W1, W2, the intermediate pillar portion CP, and the rear pillar portion RP with respect to the vehicle interior.

そして、実施形態の頭部保護エアバッグ装置Ｍでは、合成樹脂製の締結バンド５７を、折り畳まれたエアバッグ２２の折り完了体４３の周囲に巻き付けることにより、エアバッグ２２の折り崩れを防止しており、この締結バンド５７を、折り完了体４３のケース４６への組み付けにも、使用していることから、エアバッグ２２の折り畳み形状の維持と、折り完了体４３のケース４６への組み付けとを、１つの締結バンド５７で行なうことができて、部品点数の増大を抑制でき、また、従来のごとく、エアバッグの折り畳み時と、折り完了体のケースへの収納時と、に必要とされていたテープ巻き付け作業が不要となり、作業工数を低減させることができる。また、ケース４６には、取付具としての取付クリップ１７を用いてエアバッグ２２の取付部３１とともに車両Ｖのボディ１側に取り付けられる取付座５４と、締結バンド５７に形成される係止部７１を係止可能な被係止部としての係止座部５０と、が、形成されており、締結バンド５７の係止部７１は、エアバッグ組付体ＡＭ１の形成時に、取付クリップ１７を用いて取付部３１を取付座５４に仮止めする方向側となる車内側Ｉから車外側Ｏに向かうような移動によって、係止座部５０に係止させる構成とされている。すなわち、実施形態の頭部保護エアバッグ装置Ｍでは、図１８に示すように、エアバッグ組付体ＡＭ１の形成時に、取付クリップ１７によって取付部３１を取付座５４に仮止めする方向と、係止部７１を係止座部５０に係止させる方向と、が同じであることから、折り完了体４３のケースへ３６の組付時に、折り完了体４３をケース４６に収納させるようにして、作業台に一旦セットすれば、ケース４６の向きを変えることなく、取付クリップ１７による取付部３１の取付座５４への仮止めと、係止部７１の係止座部５０への係止とを、行なうことができる。そのため、取付部３１の取付座５４への仮止めと、係止部７１の係止座部５０への係止とを、簡易に行なうことができて、作業工数の増大を、抑制できる。   In the head protection airbag device M according to the embodiment, the airbag 22 is prevented from collapsing by wrapping the synthetic resin fastening band 57 around the folded body 43 of the folded airbag 22. Since the fastening band 57 is also used for assembling the folding completion body 43 to the case 46, the folding shape of the airbag 22 is maintained, and the folding completion body 43 is assembled to the case 46. Can be performed with one fastening band 57, and the increase in the number of parts can be suppressed, and it is required for folding the airbag and storing the folded body in the case as in the conventional case. The tape wrapping work that has been performed becomes unnecessary, and the number of work steps can be reduced. Further, the case 46 is provided with an attachment seat 54 attached to the body 1 side of the vehicle V together with the attachment portion 31 of the airbag 22 using an attachment clip 17 as an attachment, and a locking portion 71 formed on the fastening band 57. And a locking seat portion 50 as a locked portion that can be locked, and the locking portion 71 of the fastening band 57 uses the mounting clip 17 when the airbag assembly AM1 is formed. Thus, the mounting seat 31 is locked to the locking seat portion 50 by moving from the vehicle inner side I toward the vehicle outer side O, which is the side in which the mounting portion 31 is temporarily fixed to the mounting seat 54. That is, in the head protection airbag device M of the embodiment, as shown in FIG. 18, the direction in which the attachment portion 31 is temporarily fixed to the attachment seat 54 by the attachment clip 17 when the airbag assembly AM1 is formed, Since the direction in which the stop portion 71 is locked to the locking seat portion 50 is the same, the folding completion body 43 is accommodated in the case 46 when the folding completion body 43 is assembled to the case. Once set on the workbench, without temporarily changing the orientation of the case 46, the mounting clip 17 temporarily fixes the mounting portion 31 to the mounting seat 54 and the locking portion 71 locks to the locking seat portion 50. Can be done. Therefore, the temporary fixing of the mounting portion 31 to the mounting seat 54 and the locking of the locking portion 71 to the locking seat portion 50 can be easily performed, and an increase in work man-hours can be suppressed.

したがって、実施形態の頭部保護エアバッグ装置Ｍでは、ケース４６に収納させた状態で車両Ｖに搭載させる構成であっても、折り畳まれたエアバッグ２２のケース４６への組み付け作業が容易で、作業工数の増大を抑制できる。   Therefore, in the head protection airbag device M of the embodiment, even if the configuration is such that the airbag 22 is mounted on the vehicle V in a state of being housed in the case 46, the assembly work of the folded airbag 22 to the case 46 is easy. Increase in work man-hours can be suppressed.

実施形態では、取付具として、取付座５４に形成される取付孔５４ａに挿入可能な取付脚部２０を備えた取付クリップ１７を使用しており、エアバッグ組付体ＡＭ１の車両Ｖへの組み付けが容易であるが、このような点を考慮しなければ、取付具として、図１９に示すエアバッグ組付体ＡＭ２のように、取付部３１を挟むようにして取付部３１に取り付けられる板金製のプレート８０，８０を備える構成のものを使用してもよい。図１９に示すエアバッグ組付体ＡＭ２では、取付具を構成するプレート８０，８０は、取付部３１を挟むように２枚配置されるもので、図２０に示すように、取付部３１及びケース４６Ａの取付座８３とともにボルト８１を貫通させて、このボルト８１を、インナパネル２Ａに形成される取付孔３Ａに固着されるナット３ａに締結させることにより、取付座８３とともに、取付部３１を、車両のボディ１Ａ側に取り付ける構成とされている。プレート８０，８０は、ボルト８１を貫通させるための貫通孔８０ａを有し、貫通孔８０ａの前後両側となる二箇所でかしめられて、取付部３１を挟持させている。ケース４６Ａの取付座８３は、平板状として構成され、ボルト８１を貫通させるための貫通孔８３ａを、有している。取付座８３の前後方向の縁部側には、図２１に示すように、エアバッグ組付体ＡＭ２の形成時に、取付部３１を挟持させた状態のプレート８０，８０を、取付座８３の正面側（車内側Ｉ）から仮止め可能な係止突起（係止部）８４，８４が、車内側Ｉに突出するように形成されている。この係止突起８４は、図１９に示すように、上下方向に沿って配置されるもので、車内側Ｉに突出するように形成されるとともに、薄肉状として、前後方向側の断面形状を、先端を前後方向の内方に向けつつ車外側Ｏに向けるように、屈曲させて構成されている。この係止突起８４，８４は、車内側端縁８４ａ，８４ａ間の離隔距離を、プレート８０の前後の幅寸法より大きく設定されていることから、この係止突起８４は、エアバッグ組付体ＡＭ２の形成時に、折り完了体４３において、取付部３１を挟持させた状態のプレート８０，８０を、車内側Ｉから取付座８３側（車外側Ｏ）に向かって移動させれば、プレート８０に押圧されて前後方向の外側に向かって一旦撓み（図２１のＡの二点鎖線参照）、その後復元されて、プレート８０の前後両縁側における車外側の面に係止されることとなる。そして、係止突起８４は、取付部３１を挟持させたプレート８０，８０を、取付座８３に仮止めさせることができる。   In the embodiment, the mounting clip 17 having the mounting leg portion 20 that can be inserted into the mounting hole 54a formed in the mounting seat 54 is used as the mounting tool, and the airbag assembly AM1 is assembled to the vehicle V. However, if such a point is not taken into consideration, a plate made of sheet metal that is attached to the attachment portion 31 with the attachment portion 31 sandwiched therebetween as an attachment, such as an airbag assembly AM2 shown in FIG. You may use the thing provided with 80,80. In the airbag assembly AM2 shown in FIG. 19, two plates 80 and 80 constituting the fixture are arranged so as to sandwich the attachment portion 31, and as shown in FIG. The bolt 81 is penetrated together with the mounting seat 83 of 46A, and the bolt 81 is fastened to the nut 3a fixed to the mounting hole 3A formed in the inner panel 2A. It is set as the structure attached to the body 1A side of a vehicle. The plates 80, 80 have through holes 80 a for allowing the bolts 81 to pass therethrough, and are caulked at two locations on both the front and rear sides of the through holes 80 a to sandwich the attachment portion 31. The mounting seat 83 of the case 46A is configured as a flat plate and has a through hole 83a for allowing the bolt 81 to pass therethrough. As shown in FIG. 21, plates 80 and 80 in a state where the attachment portion 31 is sandwiched when the airbag assembly AM <b> 2 is formed are disposed on the front edge of the attachment seat 83 on the edge side in the front-rear direction of the attachment seat 83. Locking protrusions (locking portions) 84 and 84 that can be temporarily fixed from the side (inner side I) are formed so as to protrude toward the inner side I. As shown in FIG. 19, the locking projections 84 are arranged along the vertical direction and are formed so as to protrude toward the vehicle interior I. It is configured to bend so that the front end is directed inward in the front-rear direction and toward the vehicle outer side O. Since the locking projections 84 and 84 are set such that the separation distance between the vehicle inner side edges 84a and 84a is larger than the width dimension of the front and rear of the plate 80, the locking projections 84 are formed in the airbag assembly. When the plates 80 and 80 in the state in which the attachment portion 31 is sandwiched are moved from the vehicle inner side I toward the mounting seat 83 side (vehicle outer side O) in the folding completion body 43 when the AM 2 is formed, the plate 80 It is pressed and bent once toward the outside in the front-rear direction (see the two-dot chain line in FIG. 21A), then restored and locked to the vehicle outer surface on both front and rear edges of the plate 80. Then, the locking projection 84 can temporarily fix the plates 80, 80 holding the mounting portion 31 to the mounting seat 83.

また、図１９に示すエアバッグ組付体ＡＭ２では、締結バンド５７Ａに形成される係止部８８、及び、係止部８８を係止させるケース４６Ａの被係止部としての係止座部８６も、上述のエアバッグ組付体ＡＭ１と形状を異ならせて構成されている。ケース４６Ａに形成される被係止部としての係止座部８６は、図１９に示すように、取付座８３に略沿うような平板状として構成され、車内外方向に貫通して形成されて、係止部８８を構成する突出片部８９の先端側部位８９ａを周縁で係止可能な略長方形状に開口した係止孔８６ａを、有している（図２１参照）。係止部８８は、締結バンド５７Ａにおける箱状体６９Ａの車外側の面から車外側Ｏに向かって突出するとともに前後方向側で配置される一対の突出片部８９から構成されている。突出片部８９は、図２２に示すように、先端側を前後方向の外方に向けて突出させるように構成されるもので、この先端側部位８９ａは、前後方向の外方側の縁部を、傾斜させるようにして、先細り状とされている。また、先端側部位８９ａ，８９ａは、車外側端末８９ｂ，８９ｂ間の離隔距離を、係止孔８６ａの前後の開口幅寸法より小さく設定されていることから、エアバッグ組付体ＡＭ２の形成時に、この係止部８８（突出片部８９）を、係止座部８６側（車外側Ｏ）に向かって移動させれば、突出片部８９が、係止孔８６ａに挿通される際に、先端側部位８９ａの前後方向の外方側の縁部をガイドとして、先端側部位８９ａを前後の中央側に向けるように撓み、その後、復元されて、先端側部位８９ａを係止孔８６ａ周縁に係止されることとなる。   Further, in the airbag assembly AM2 shown in FIG. 19, a locking portion 88 formed on the fastening band 57A and a locking seat portion 86 as a locked portion of the case 46A for locking the locking portion 88. Also, the shape is different from that of the above-described airbag assembly AM1. As shown in FIG. 19, the locking seat portion 86 as the locked portion formed in the case 46 </ b> A is configured as a flat plate shape substantially along the mounting seat 83, and is formed so as to penetrate in the vehicle interior / exterior direction. In addition, it has a locking hole 86a that is open in a substantially rectangular shape that can lock the distal end side portion 89a of the protruding piece 89 constituting the locking portion 88 at the periphery (see FIG. 21).
