（作用）
　本実施形態は、上記のように構成されており、以下その作用について説明する。図２，図４から図６において、本実施形態に係るグラブドア付けニーエアバッグ装置１０では、エアバッグモジュール１６が、グラブドア１４内におけるアウタパネル３２とインナパネル３４との間に設けられると共に、該アウタパネル３２の裏面３２Ａに対して締結固定され、該インナパネル３４はアウタパネル３２と一体的に組み合わせて構成されるので、インナパネル３４においてエアバッグモジュール１６組付け用の開口を塞ぐためのカバーを廃止することができる。特に、本実施形態では、アウタパネル３２の裏面３２Ａに取付けボス５０が設けられ、エアバッグモジュール１６は、該取付けボス５０に対して締結固定されているので、簡単な構成により、インナパネル３４の形状を単純化して、コストの低減を図ることができる。また上記カバーを廃止することで、エアバッグモジュール１６に接続されるワイヤハーネス（図示せず）を保持するための、コルゲートチューブ等の部材（図示せず）も不要となる。 (Function)
This embodiment is configured as described above, and the operation thereof will be described below. 2 and 4 to 6, in the glove door-attached knee airbag device 10 according to the present embodiment, the airbag module 16 is provided between the outer panel 32 and the inner panel 34 in the grab door 14, and the outer panel. Since the inner panel 34 is integrally combined with the outer panel 32, the cover for closing the opening for assembling the airbag module 16 in the inner panel 34 is abolished. be able to. In particular, in the present embodiment, the mounting boss 50 is provided on the back surface 32A of the outer panel 32, and the airbag module 16 is fastened and fixed to the mounting boss 50. Therefore, the shape of the inner panel 34 can be achieved with a simple configuration. The cost can be reduced. Further, by eliminating the cover, a member (not shown) such as a corrugated tube for holding a wire harness (not shown) connected to the airbag module 16 becomes unnecessary.
　取付けボス５０には、エアバッグモジュール１６の締結固定に用いられる固定ねじ５２に対応するナット５４がインサート成形されているので、該ナット５４に固定ねじ５２を締め付けることにより、エアバッグモジュール１６をグラブドア１４のアウタパネル３２に固定することができる。このため、エアバッグモジュール１６の組付け作業を容易に行うことができる。 Since a nut 54 corresponding to a fixing screw 52 used for fastening and fixing the airbag module 16 is insert-molded on the mounting boss 50, the airbag module 16 is attached to the grab door by fastening the fixing screw 52 to the nut 54. 14 outer panels 32 can be fixed. For this reason, the assembly | attachment operation | work of the airbag module 16 can be performed easily.
　このエアバッグモジュール１６の組付け作業について簡単に説明すると、グラブドア１４のアウタパネル３２に、予めエアバッグドア部材３６を接合しておき、該エアバッグドア部材３６における縦壁部３６Ｂの貫通孔３６Ｄに、エアバッグモジュール１６のフック４８を係止するようにして、仮組付けを行う。このとき、エアバッグモジュール１６の取付けブラケット５６が、各取付けボス５０に概ね対応するように位置決めされる。 Briefly describing the assembling operation of the airbag module 16, an airbag door member 36 is joined in advance to the outer panel 32 of the grab door 14, and the airbag door member 36 is inserted into the through hole 36D of the vertical wall portion 36B. Temporary assembly is performed so that the hook 48 of the airbag module 16 is locked. At this time, the mounting bracket 56 of the airbag module 16 is positioned so as to substantially correspond to each mounting boss 50.
　この状態で、図２，図４から図６に示されるように、固定ねじ５２を取付けブラケット５６における貫通孔５６Ｃに通し、取付けボス５０内のナット５４に締結することで、アウタパネル３２の裏面３２Ａに対するエアバッグモジュール１６の締結固定が完了する。そして、図１，図６に示されるように、インナパネル３４をアウタパネル３２に溶着することで、該アウタパネル３２とインナパネル３４とが一体化して、グラブドア１４となる。 In this state, as shown in FIGS. 2, 4 to 6, the fixing screw 52 is passed through the through hole 56 </ b> C in the mounting bracket 56 and fastened to the nut 54 in the mounting boss 50. Fastening and fixing of the airbag module 16 with respect to is completed. As shown in FIGS. 1 and 6, the inner panel 34 is welded to the outer panel 32, whereby the outer panel 32 and the inner panel 34 are integrated to form the grab door 14.
　次に、車両の例えば前面衝突時におけるグラブドア付けニーエアバッグ装置１０の作用について説明する。車両が例えば前面衝突時し、衝突センサからの信号に基づいて、エアバッグＥＣＵが該前面衝突の発生を判定すると、インフレータ４０に対して点火電流が流される。インフレータ４０は、該点火電流により作動して、多量のガスを発生させる。このガスがニーエアバッグ３８に供給されることで、該ニーエアバッグ３８が膨張展開し始める。 Next, the operation of the knee airbag device 10 with a grab door at the time of a frontal collision of the vehicle will be described. For example, when the vehicle has a frontal collision and the airbag ECU determines the occurrence of the frontal collision based on a signal from the collision sensor, an ignition current is supplied to the inflator 40. The inflator 40 is activated by the ignition current to generate a large amount of gas. By supplying this gas to the knee airbag 38, the knee airbag 38 starts to expand and deploy.
　このとき、図１において、ニーエアバッグ３８は、モジュールケース４２とエアバッグドア部材３６（アウタパネル３２）との間で膨張しようとするので、ニーエアバッグ３８の展開初期における膨張圧は、該モジュールケース４２とエアバッグドア部材３６とを互いに引き離す方向に作用する。しかしながら、モジュールケース４２は、フック４８によりエアバッグドア部材３６の縦壁部３６Ｂに係止されており、図４から図６に示されるように、更に取付けブラケット５６を介して、アウタパネル３２の裏面３２Ａの取付けボス５０に直接的に締結固定されている。即ち、エアバッグモジュール１６は、比較的軟質の合成樹脂により構成されたエアバッグドア部材３６に係止されるだけでなく、比較的硬質の合成樹脂により構成されたアウタパネル３２に対して締結固定されている。従って、比較的軟質のエアバッグドア部材３６にエアバッグモジュール１６を係止するだけの構造と比べて、組付け強度を飛躍的に高めることができる。 At this time, in FIG. 1, the knee airbag 38 tends to inflate between the module case 42 and the airbag door member 36 (outer panel 32). The case 42 and the airbag door member 36 act in a direction to separate them from each other. However, the module case 42 is locked to the vertical wall portion 36B of the airbag door member 36 by the hook 48, and further, as shown in FIGS. 4 to 6, the back surface of the outer panel 32 via the mounting bracket 56. It is fastened and fixed directly to the mounting boss 50 of 32A. That is, the airbag module 16 is not only locked to the airbag door member 36 made of a relatively soft synthetic resin, but also fastened and fixed to the outer panel 32 made of a relatively hard synthetic resin. ing. Therefore, the assembling strength can be remarkably increased as compared with the structure in which the airbag module 16 is merely locked to the relatively soft airbag door member 36.
　このようにアウタパネル３２に対するエアバッグモジュール１６の組付け強度が高いため、ニーエアバッグ３８の膨張圧により、エアバッグモジュール１６がアウタパネル３２側から離脱することはない。従って、ニーエアバッグ３８の展開初期の反力をモジュールケース４２において生じさせ、該ニーエアバッグ３８の膨張圧からエアバッグドア部材３６（アウタパネル３２）側に有効に作用させることができる。 Since the assembly strength of the airbag module 16 with respect to the outer panel 32 is high as described above, the airbag module 16 is not detached from the outer panel 32 side due to the inflation pressure of the knee airbag 38. Accordingly, a reaction force at the initial stage of deployment of the knee airbag 38 can be generated in the module case 42 and can be effectively applied to the airbag door member 36 (outer panel 32) side from the inflation pressure of the knee airbag 38.
　この膨張圧により、エアバッグドア部材３６のティアライン３６Ｔ及びアウタパネル３２のティアライン３２Ｅ，３２Ｔが破断することで、一対のドア基材３６Ｃが、上下のヒンジ部３６Ｅを中心として、アウタパネル３２の一部と共に車室２８側へ夫々展開する。この際、ティアライン３２Ｔの溝深さは、ティアライン３２Ｅの溝深さよりも深く設定されているため、ティアライン３２Ｔがティアライン３２Ｅに先行して破断する。このようにして、アウタパネル３２に開口部が形成される（図示せず）。ニーエアバッグ３８は、この開口部を通じて、グラブドア１４内から車室２８側へ膨出し、展開して行く。このニーエアバッグ３８により、乗員６０の膝部６０Ｋ（図１）を拘束することができる。 Due to the inflation pressure, the tear line 36T of the airbag door member 36 and the tear lines 32E and 32T of the outer panel 32 are broken, so that the pair of door base materials 36C is formed in the outer panel 32 around the upper and lower hinge portions 36E. Deploy to the vehicle compartment 28 side with each part. At this time, since the groove depth of the tear line 32T is set deeper than the groove depth of the tear line 32E, the tear line 32T breaks prior to the tear line 32E. In this way, an opening is formed in the outer panel 32 (not shown). The knee airbag 38 bulges from the inside of the grab door 14 toward the vehicle compartment 28 through the opening, and is deployed. With the knee airbag 38, the knee 60K (FIG. 1) of the occupant 60 can be restrained.
　なお、図示は省略するが、グラブドア１４の補強のために、アウタパネル３２の裏面３２Ａにリブを設け、該リブとインナパネル３４とを溶着するようにしてもよい。 Although illustration is omitted, for reinforcement of the grab door 14, a rib may be provided on the back surface 32A of the outer panel 32, and the rib and the inner panel 34 may be welded.
［第２実施形態］
　図７から図１１において、本実施の形態に係るグラブドア付けニーエアバッグ装置２０では、アウタパネル３２の裏面３２Ａに取付け部６２が突出形成されており、エアバッグモジュール１６は、該取付け部６２を、エアバッグモジュール１６から延びる取付けブラケット５６と別体の当て部材６４とにより挟み込んで締結することで固定されている。 [Second Embodiment]
7 to 11, in the knee airbag device 20 with a grab door according to the present embodiment, a mounting portion 62 protrudes from the back surface 32A of the outer panel 32, and the airbag module 16 includes the mounting portion 62, The mounting bracket 56 extending from the airbag module 16 and a separate abutting member 64 are sandwiched and fastened to fix.
　具体的には、取付け部６２は、例えばアウタパネル３２に一体成形されており、エアバッグドア部材３６の車幅方向両側に１箇所ずつ設けられている。また取付け部６２は、アウタパネル３２の裏面３２Ａに立設された一対の脚部６２Ａと、該一対の脚部６２Ａを例えばアウタパネル３２の裏面３２Ａと略平行に連結する座部６２Ｂとを有して構成されている。座部６２Ｂには、固定ねじ５２を通すための貫通孔６２Ｃが、例えば２箇所ずつ形成されている。また座部６２Ｂの例えば長手方向中央部には、裏面３２Ａ側に突出する突起６２Ｄが一体的に形成されている。図９に示されるように、突起６２Ｄの周囲には、例えばＵ字形のスリット６２Ｅが形成されており、これによって突起６２Ｄが座部６２Ｂの厚さ方向に弾性的に揺動可能に構成されている。 Specifically, the attachment portion 62 is integrally formed with the outer panel 32, for example, and is provided at one location on each side of the airbag door member 36 in the vehicle width direction. The mounting portion 62 includes a pair of leg portions 62A erected on the back surface 32A of the outer panel 32, and a seat portion 62B that connects the pair of leg portions 62A, for example, substantially parallel to the back surface 32A of the outer panel 32. It is configured. In the seat portion 62B, through holes 62C through which the fixing screws 52 are passed are formed, for example, at two locations. In addition, a protrusion 62D that protrudes toward the back surface 32A is integrally formed, for example, at the center in the longitudinal direction of the seat 62B. As shown in FIG. 9, for example, a U-shaped slit 62E is formed around the protrusion 62D, and the protrusion 62D is configured to be elastically swingable in the thickness direction of the seat 62B. Yes.
　当て部材６４は、取付け部６２の座部６２Ｂの裏面側（座部６２Ｂとアウタパネル３２との間）に重ねることが可能な寸法を有する、例えば金属製の板状部材であり、貫通孔６２Ｃに対応する貫通孔６４Ｃと、突起６２Ｄに対応する例えば貫通孔６４Ｄとを有して構成されている。当て部材６４において、貫通孔６４Ｃに対応する部位の裏面には、固定ねじ５２が螺合するナット５４が、例えば溶接により固着されている。 The abutting member 64 is a plate-like member made of, for example, metal having a dimension that can be superimposed on the back surface side (between the seat portion 62B and the outer panel 32) of the seat portion 62B of the mounting portion 62, and the through-hole 62C. It has a corresponding through hole 64C and, for example, a through hole 64D corresponding to the protrusion 62D. In the abutting member 64, a nut 54 to which the fixing screw 52 is screwed is fixed to the back surface of the portion corresponding to the through hole 64C by, for example, welding.
　なお、取付け部６２における座部６２Ｂの裏面側に支持部（図示せず）を設けて、当て部材６４を差し込み可能としてもよい。この場合、当て部材６４を取付け部６２の裏面側に差し込むと、突起６２Ｄが一旦弾性的に揺動した後、当て部材６４の貫通孔６４Ｄに係合する。従って、エアバッグモジュール１６のアウタパネル３２への組付けに先立って、当て部材６４を取付け部６２に対して安定的に取り付けておくことができる。またこれによって、固定ねじ５２をナット５４に締結する際の作業性をより向上させることができる。 In addition, it is good also as a support part (not shown) provided in the back surface side of the seat part 62B in the attaching part 62, and making it possible to insert the contact member 64. FIG. In this case, when the abutting member 64 is inserted into the back surface side of the mounting portion 62, the protrusion 62 </ b> D once elastically swings and then engages with the through hole 64 </ b> D of the abutting member 64. Therefore, prior to assembly of the airbag module 16 to the outer panel 32, the abutting member 64 can be stably attached to the attachment portion 62. This also makes it possible to further improve the workability when fastening the fixing screw 52 to the nut 54.
　なお、取付け部６２に上記のような支持部（図示せず）を設けない場合には、突起６２Ｄは、座部６２Ｂの厚さ方向に弾性的に揺動可能でなくてもよい。また当て部材６４の貫通孔６４Ｄの代わりに、突起６２Ｄが係合可能な凹部（図示せず）を設けてもよい。図示の例では、取付け部６２の座部６２Ｂとアウタパネル３２の裏面３２Ａとの間が車幅方向に貫通した状態となっているが、これに限られず、例えば取付け部６２の車幅方向における一方の端部を閉じるように構成してもよい。取付け部６２の強度が向上することで、アウタパネル３２に対するエアバッグモジュール１６の取付け強度もより向上するからである。 Note that if the mounting portion 62 is not provided with a support portion (not shown) as described above, the projection 62D may not be elastically swingable in the thickness direction of the seat portion 62B. Moreover, you may provide the recessed part (not shown) in which protrusion 62D can engage instead of through-hole 64D of the contact member 64. FIG. In the illustrated example, the space between the seat portion 62B of the mounting portion 62 and the back surface 32A of the outer panel 32 is penetrated in the vehicle width direction. However, the present invention is not limited to this, for example, one side of the mounting portion 62 in the vehicle width direction. You may comprise so that the edge part of may be closed. This is because the strength of the attaching portion 62 is improved, and the strength of attaching the airbag module 16 to the outer panel 32 is further improved.
