Japanese Patent Laid-Open No. 9-2188 (paragraph 0038, FIG. 1) JP 2004-148909 A (paragraph 0016 column, FIG. 8)

しかし、特許文献１では、汎用樹脂材に比べて高価な熱可塑性エラストマー材を使用しており、また、特許文献２では、フラップ部が余分に必要であるとともに該フラップ部をエアバッグドア部裏面に溶着する手間が掛かり、いずれにしてもコストアップを招来する。   However, in Patent Document 1, a thermoplastic elastomer material that is more expensive than a general-purpose resin material is used, and in Patent Document 2, an additional flap portion is necessary and the flap portion is attached to the back surface of the airbag door portion. It takes a lot of time and effort to weld it, which incurs a cost increase anyway.

この発明はかかる点に鑑みてなされたものであり、その目的とするところは、エアバッグドア部がエアバッグ展開時の衝撃で飛散しないインストルメントパネル等の車両用内装品を廉価に提供することである。   The present invention has been made in view of the above points, and an object of the present invention is to provide inexpensive interior parts for a vehicle such as an instrument panel in which an airbag door portion does not scatter due to an impact when the airbag is deployed. It is.

上記の目的を達成するため、この発明は、エアバッグドア部を内装品本体の一部で構成するとともに、エアバッグドア部の回動支点となるヒンジ部及びその周りの構造を工夫したことを特徴とし、具体的には、次のような解決手段を講じた。   In order to achieve the above object, the present invention is that the airbag door portion is constituted by a part of the interior body, and that the hinge portion serving as a pivotal fulcrum of the airbag door portion and the structure around it are devised. Specifically, the following solutions were taken.

すなわち、請求項１に記載の発明は、エアバッグドア部を形成する第１脆弱部と、少なくとも上記エアバッグドア部の端縁から外側に延び湾曲変形可能な複数の板状ヒンジ部をエアバッグドア部の端縁に沿って間隔をあけて形成する第２脆弱部とが内装品本体にその表面から識別できないようにそれぞれ形成され、第２脆弱部形成領域の上記ヒンジ部を除く非ヒンジ部の内装品本体裏面には、エアバッグ装置取付部が設けられているとともに、該エアバッグ装置取付部と上記第１脆弱部との間には突起部がエアバッグドア部の端縁に沿うように突設され、上記エアバッグドア部裏面に対応するように固定側に支持されたエアバッグ装置がブラケット部材を介して上記エアバッグ装置取付部に取り付けられているとともに、上記ブラケット部材と上記突起部とが係合しており、上記第１脆弱部及び第２脆弱部は上記エアバッグ装置の作動により破断し、上記エアバッグドア部はヒンジ部の一端に一体に接続された状態で内装品本体と切り離されて開くとともに、上記ヒンジ部は他端が内装品本体に一体に接続された状態で非ヒンジ部と切り離されて湾曲変形しながら内装品本体から起き上がるように構成されていることを特徴とする。   In other words, the invention described in claim 1 includes an airbag including a first fragile portion forming an airbag door portion and at least a plurality of plate-like hinge portions that extend outward from an edge of the airbag door portion and can be deformed in a curved manner. A non-hinge portion excluding the hinge portion in the second weakened portion forming region, wherein the second weakened portion formed at intervals along the edge of the door portion is formed on the interior product main body so that it cannot be identified from the surface thereof. An air bag device mounting portion is provided on the rear surface of the interior product body, and a protruding portion extends along the edge of the air bag door portion between the air bag device mounting portion and the first fragile portion. And an airbag device supported on the fixed side so as to correspond to the back surface of the airbag door portion is attached to the airbag device mounting portion via a bracket member, and the bracket member The protrusion is engaged, the first fragile portion and the second fragile portion are broken by the operation of the airbag device, and the airbag door portion is integrally connected to one end of the hinge portion. The hinge part is separated from the non-hinge part with the other end integrally connected to the interior part body and is raised from the interior part body while being bent and deformed while being separated from the interior part body and opened. It is characterized by that.

請求項２に記載の発明は、請求項１に記載の発明において、ブラケット部材には係合孔がエアバッグドア部の端縁に沿うように形成され、突起部が上記係合孔に挿入されて上記ブラケット部材と係合していることを特徴とする。   According to a second aspect of the present invention, in the first aspect of the present invention, the bracket member is formed with an engagement hole along the edge of the airbag door portion, and the protrusion is inserted into the engagement hole. The bracket member is engaged with the bracket member.

請求項３に記載の発明は、請求項１に記載の発明において、ブラケット部材が突起部のエアバッグドア部側の側面に当接して該突起部と係合していることを特徴とする。   According to a third aspect of the present invention, in the first aspect of the invention, the bracket member is in contact with the side surface of the protrusion portion on the airbag door portion side and is engaged with the protrusion portion.

請求項４に記載の発明は、請求項１乃至３のいずれか１項に記載の発明において、ブラケット部材は、エアバッグ装置の少なくともヒンジ部側全幅に亘って第１脆弱部よりも内側寄りのエアバッグドア部裏面に向けて延び、エアバッグ装置の作動により展開するエアバッグをエアバッグドア部裏面に導くガイドプレートを兼ねていることを特徴とする。   The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the bracket member is closer to the inside than the first fragile portion over at least the entire width of the hinge portion of the airbag device. It extends toward the back surface of the airbag door portion, and also serves as a guide plate for guiding the airbag deployed by the operation of the airbag device to the back surface of the airbag door portion.

請求項１に係る発明によれば、車両が衝突してエアバッグ装置が作動すると、エアバッグが展開してその展開圧力がエアバッグドア部に作用し、第１脆弱部及び第２脆弱部が破断する。これにより、エアバッグドア部がヒンジ部の一端に一体に接続された状態で内装品本体と切り離されて開くとともに、上記ヒンジ部の他端が内装品本体に一体に接続された状態でヒンジ部が非ヒンジ部と切り離されて湾曲変形しながら内装品本体から起き上がる。   According to the first aspect of the present invention, when the airbag device is activated due to the collision of the vehicle, the airbag is deployed and the deployment pressure acts on the airbag door portion, and the first fragile portion and the second fragile portion are Break. As a result, the airbag door part is separated and opened from the interior part main body while being integrally connected to one end of the hinge part, and the hinge part is connected to the interior part main body while the other end of the hinge part is integrally connected to the interior part main body. Rises from the interior body while being bent and deformed by being separated from the non-hinge part.

この際、上記非ヒンジ部はエアバッグ装置取付部、ブラケット部材及びエアバッグ装置を介して固定側に支持されているので、エアバッグドア部が開いたりヒンジ部が起き上がってもその動作に影響されずに動かず、第２脆弱部が速やかに破断し、しかも、ヒンジ部は連続せずにエアバッグドア部の端縁に沿って間隔をあけて複数形成されていて回動抵抗が少なく、よって、エアバッグドア部を確実に開くことができる。特に、上記ブラケット部材と非ヒンジ部の突起部とが係合しているので、エアバッグドア部開時に、ヒンジ部の起き上がり動作に伴う引き上げ力が非ヒンジ部に作用しても、該非ヒンジ部はこの引き上げ力に十分に抗して安定した不動状態を確保でき、ヒンジ部を非ヒンジ部から確実に切り離してエアバッグドア部の開動作を安定させてエアバッグドア部の展開性能を高めることができる。   At this time, since the non-hinge portion is supported on the fixed side via the airbag device mounting portion, the bracket member, and the airbag device, the operation is affected even if the airbag door portion is opened or the hinge portion is raised. The second fragile portion breaks quickly, and the hinge portion is not continuous and is formed with a plurality of intervals along the edge of the airbag door portion so that the rotational resistance is small. The airbag door can be reliably opened. In particular, since the bracket member and the projection of the non-hinge portion are engaged, even if the lifting force accompanying the raising operation of the hinge portion acts on the non-hinge portion when the airbag door portion is opened, the non-hinge portion Can sufficiently resist this pulling force to ensure a stable immobilization state, reliably disconnect the hinge part from the non-hinge part, stabilize the opening operation of the airbag door part, and improve the deployment performance of the airbag door part Can do.

また、上記ヒンジ部は湾曲変形可能な板状に形成されているため、エアバッグドア部開時に起き上がりながら弧状に湾曲変形してエアバッグの展開圧力を効果的に吸収し、よってエアバッグドア部に対するエアバッグの過剰な展開圧力の作用をなくすとともに、ヒンジ部を千切れないようにすることができ、エアバッグドア部の飛散を防止することができる。   In addition, since the hinge portion is formed in a plate shape that can be bent and deformed, the hinge portion is bent and deformed in an arc shape while rising when the airbag door portion is opened, thereby effectively absorbing the deployment pressure of the airbag. In addition, the excessive deployment pressure of the airbag can be eliminated, the hinge portion can be prevented from being broken, and the airbag door portion can be prevented from being scattered.

さらに、エアバッグドア部を内装品本体の一部で構成しているので、特許文献１のような高価な熱可塑性エラストマー材でエアバッグドア部を成形する場合や、特許文献２のようなフラップ部をエアバッグドア部の裏面に溶着する場合に比べて廉価な内装品とすることができる。   Furthermore, since the airbag door part is comprised by a part of interior product main body, when forming an airbag door part with an expensive thermoplastic elastomer material like patent document 1, or a flap like patent document 2 Compared to the case where the portion is welded to the back surface of the airbag door portion, the interior can be made cheaper.

請求項２に係る発明によれば、突起部をブラケット部材の係合孔に挿入してヒンジ部の引き上げ力に抗しているので、ブラケット部材と突起部との係合を確実に行うことができる。   According to the second aspect of the invention, since the protrusion is inserted into the engagement hole of the bracket member and resists the lifting force of the hinge part, the engagement between the bracket member and the protrusion can be reliably performed. it can.

請求項３に係る発明によれば、ブラケット部材を突起部のエアバッグドア部側の側面に当接させてヒンジ部の引き上げ力に抗しているので、請求項２のような係合孔がいらず、また、突起部を係合孔に位置合わせして挿入しなくてよく、ブラケット部材の加工及び取付けを簡単に行うことができる。   According to the invention of claim 3, since the bracket member is brought into contact with the side surface of the protrusion on the airbag door portion side to resist the lifting force of the hinge portion, the engagement hole as in claim 2 is provided. In addition, it is not necessary to align and insert the protruding portion into the engaging hole, and the bracket member can be easily processed and attached.

請求項４に係る発明によれば、ブラケット部材がエアバッグをエアバッグドア部裏面に導くガイドプレートを兼ねているので、別途にガイドプレートを設けなくて済む分だけ部品点数を削減することができる。   According to the invention of claim 4, since the bracket member also serves as a guide plate for guiding the airbag to the back surface of the airbag door portion, the number of parts can be reduced by the amount that it is not necessary to provide a separate guide plate. .

以下、この発明の実施形態について図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施形態１）
図１及び図４は車両用インストルメントパネルにおけるアッパパネルの右側半分を構成するパネル構成部材１を示し、このパネル構成部材１が実施形態１に係るエアバッグドア部付き車両用内装品である。このパネル構成部材１は、左ハンドル車用のもので運転席右隣の助手席側に配置され、例えばポリプロピレン（ＰＰ）等の汎用樹脂材で射出成形された単一材からなるパネル構成部材本体３を備えているが、該パネル構成部材本体３は表皮材が基材に一体に被着された２層構造であってもよい。 (Embodiment 1)
1 and 4 show a panel constituent member 1 that constitutes the right half of an upper panel in a vehicle instrument panel, and this panel constituent member 1 is a vehicle interior part with an airbag door portion according to the first embodiment. The panel component member 1 is for a left-hand drive vehicle, is disposed on the passenger seat side adjacent to the right side of the driver's seat, and is a panel component member body made of a single material that is injection-molded with a general-purpose resin material such as polypropylene (PP). 3, the panel component main body 3 may have a two-layer structure in which the skin material is integrally attached to the base material.

上記パネル構成部材本体３裏面の助手席対応箇所には、図２及び図３にも示すように、断面略Ｖ字状の第１破断溝部５が表面に達しないように型成形により平面視略矩形状に形成され、該第１破断溝部５に対応する薄肉部で平面視略矩形状の第１脆弱部７がパネル構成部材本体３にその表面から識別できないように形成されて、該第１脆弱部７で囲まれる内側に片開きタイプのエアバッグドア部９がパネル構成部材本体３の一部で一体に形成されている。なお、車体前方側の車幅方向に延びる第１脆弱部７（第１破断溝部５）は３箇所で分断されている。   As shown in FIGS. 2 and 3, the portion corresponding to the front passenger seat on the back surface of the panel component member body 3 is substantially cut in plan view by molding so that the first fracture groove portion 5 having a substantially V-shaped cross section does not reach the surface. A first fragile portion 7 which is formed in a rectangular shape and is a thin portion corresponding to the first breaking groove portion 5 and has a substantially rectangular shape in plan view is formed on the panel component member body 3 so that it cannot be identified from the surface thereof. On the inner side surrounded by the fragile portion 7, a single-opening type airbag door portion 9 is formed integrally with a part of the panel constituent member main body 3. In addition, the 1st weak part 7 (1st fracture | rupture groove part 5) extended in the vehicle width direction of the vehicle body front side is divided | segmented at three places.

上記エアバッグドア部９の車体前方端縁には、６本の断面略Ｖ字状の第２破断溝部１１が、エアバッグドア部９の車体前方端縁から外側に延びるように、かつエアバッグドア部９の車体前方端縁に沿って間隔をあけて表面に達しないように型成形によりそれぞれ形成されている。これら第２破断溝部１１は２本ずつ接近して配置され、この２本の接近する第２破断溝部１１は、車体前後方向に延びる直線を中心に互いに中央を接近するように略弓状に湾曲して線対称に配置されている。上記６本の第２破断溝部１１のうち車幅方向両端の２本の第２破断溝部１１は、車幅方向両端の第１破断溝部５に連続し、他の４本の第２破断溝部１１のうち隣り合う２本の第２破断溝部１１は、車体前方側の第１破断溝部５で連結されて該第１破断溝部５とで略コの字形状を呈している。そして、上記第２破断溝部１１に対応する薄肉部で６つの第２脆弱部１３がエアバッグドア部９の車体前方端縁に沿って間隔をあけてパネル構成部材本体３にその表面から識別できないように形成されて、隣り合う３箇所の第２脆弱部１３間に湾曲変形可能な３つの板状ヒンジ部１５がエアバッグドア部９の車体前方端縁に沿ってそれぞれ間隔をあけてパネル構成部材本体３の一部で一体に形成されている。これにより、上記エアバッグドア部９及びヒンジ部１５は、第１脆弱部７及び第２脆弱部１３がパネル構成部材本体３表面から識別できない，いわゆるシームレスタイプに構成されている。なお、上記第２破断溝部１１を略弓状に湾曲させているのは、エアバッグドア部９開時に破断する勢いを弱め、第２脆弱部１３の亀裂が車体前方に必要以上に走らないようにするためである。また、上記第２脆弱部１３（第２破断溝部１１）はエアバッグドア部９の車体前方端縁から内側に延びていてもよい。   At the vehicle body front end edge of the airbag door portion 9, six second fracture grooves 11 having a substantially V-shaped cross section extend outward from the vehicle body front end edge of the airbag door portion 9, and the airbag. The door portions 9 are respectively formed by molding so as not to reach the surface with a space along the front edge of the vehicle body. The two second breaking groove portions 11 are arranged close to each other, and the two approaching second breaking groove portions 11 are curved in a substantially arcuate shape so as to approach each other around a straight line extending in the longitudinal direction of the vehicle body. Are arranged in line symmetry. Of the six second breaking groove portions 11, two second breaking groove portions 11 at both ends in the vehicle width direction are continuous with the first breaking groove portions 5 at both ends in the vehicle width direction, and the other four second breaking groove portions 11. The two adjacent second fracture groove portions 11 are connected by the first fracture groove portion 5 on the front side of the vehicle body and have a substantially U-shape with the first fracture groove portion 5. And the 6 2nd weak parts 13 are spaced apart along the vehicle body front edge of the airbag door part 9 by the thin part corresponding to the said 2nd fracture | rupture groove part 11, and cannot identify the panel structural member main body 3 from the surface. The three plate-like hinge parts 15 that are formed as described above and that can be curved and deformed between three adjacent second weakened parts 13 are spaced apart from each other along the front edge of the vehicle body of the airbag door part 9. A part of the member body 3 is integrally formed. Thereby, the said airbag door part 9 and the hinge part 15 are comprised by what is called a seamless type in which the 1st weak part 7 and the 2nd weak part 13 cannot be distinguished from the panel structural member main body 3 surface. The second rupture groove 11 is curved in a substantially arcuate shape to weaken the momentum of rupture when the airbag door 9 is opened so that the crack of the second fragile portion 13 does not run more than necessary in front of the vehicle body. It is to make it. The second fragile portion 13 (second fracture groove portion 11) may extend inward from the vehicle body front edge of the airbag door portion 9.

上記第１脆弱部７を形成する領域Ａ１における車体後方外側近傍のパネル構成部材本体３裏面には、車幅方向に延びる第１脆弱部７に沿うように板状の係止壁部１７が一体に突設され、該係止壁部１７には係止孔１７ａが車幅方向に間隔をあけて５個形成されている。該係止壁部１７基端（上端）には、成形時の熱収縮差によるヒケがパネル構成部材本体３表面に生じ難いように盗み部１７ｂが全長に亘って凹設されているとともに、係止壁部１７両面には補強リブ部１９が車幅方向に間隔をあけて４個ずつ形成されている。一方、上記第２脆弱部１３を形成する領域Ａ２における上記ヒンジ部１５を除く４箇所の非ヒンジ部２１のパネル構成部材本体３裏面には、ネジ孔（図示せず）を有するエアバッグ装置取付部としての取付ボス部２３が３個の補強リブ部２５で補強された状態で車幅方向に間隔をあけて一体に突設されている。これら４個の取付ボス部２３のうち車幅方向両端を除く２個の取付ボス部２３と車体前方側の第１脆弱部７との間には、矩形板状の突起部２７がエアバッグドア部９の車体前方端縁に沿うように一体に突設されている。   A plate-like locking wall portion 17 is integrated with the back surface of the panel constituent member main body 3 in the vicinity of the rear outside of the vehicle body in the region A1 forming the first fragile portion 7 so as to extend along the first fragile portion 7 extending in the vehicle width direction. The locking wall portion 17 is formed with five locking holes 17a at intervals in the vehicle width direction. At the base end (upper end) of the locking wall 17, a stealing portion 17 b is provided over the entire length so that sink marks due to a difference in thermal shrinkage during molding hardly occur on the surface of the panel component member body 3. Four reinforcing rib portions 19 are formed on both surfaces of the stop wall portion 17 at intervals in the vehicle width direction. On the other hand, in the area A2 where the second fragile portion 13 is formed, the airbag device attachment having screw holes (not shown) on the back surface of the panel component member body 3 of the four non-hinge portions 21 excluding the hinge portion 15 is provided. The mounting boss portion 23 as a portion is reinforced with three reinforcing rib portions 25 so as to project integrally with an interval in the vehicle width direction. A rectangular plate-shaped protrusion 27 is formed between the two mounting bosses 23 excluding both ends in the vehicle width direction and the first fragile part 7 on the front side of the vehicle body, and is the airbag door. The unit 9 is integrally protruded along the front end edge of the vehicle body.

上記第１脆弱部形成領域Ａ１の車幅方向両外側近傍のパネル構成部材本体３裏面にも、取付ボス部２９がそれぞれ２個ずつ一体に突設されている。また、上記第２脆弱部形成領域Ａ２を挟んでエアバッグドア部９と対向する側のパネル構成部材本体３裏面には、平面視横長矩形の枠状をした剛性リブ部３１が車幅方向に延びるように一体に突設されている。該剛性リブ部３１は、複数の板状縦リブ部３１ａ及び横リブ部３１ｂを縦横に組み合わせた格子状の組み合わせ体からなり、第２脆弱部形成領域Ａ２外周りのパネル構成部材本体３の剛性を高めている。   Two mounting boss portions 29 are integrally protruded on the back surface of the panel constituent member body 3 in the vicinity of both outer sides in the vehicle width direction of the first fragile portion forming area A1. In addition, a rigid rib portion 31 having a frame shape that is horizontally long in a plan view is provided in the vehicle width direction on the rear surface of the panel component member body 3 on the side facing the airbag door portion 9 across the second fragile portion forming area A2. It protrudes integrally so as to extend. The rigid rib portion 31 is composed of a grid-like combination body in which a plurality of plate-like vertical rib portions 31a and horizontal rib portions 31b are combined vertically and horizontally, and the rigidity of the panel component member body 3 around the second weakened portion forming region A2 is around. Is increasing.

これにより、例えば、厚肉のブロック状のもので剛性リブ部３１を構成する場合に比べて軽量であり、また、材料が少なくて済むため剛性リブ部３１を安価に成形することができる。また、剛性リブ部３１とパネル構成部材本体３裏面との接触面積が小さくなる分だけ、成形時に熱収縮差によるヒケがパネル構成部材本体３表面に生じ難くなって見栄えを向上させることができる。   Thereby, for example, the rigid rib portion 31 can be formed at a low cost because it is lighter than the case where the rigid rib portion 31 is formed of a thick block shape and requires less material. Further, as the contact area between the rigid rib portion 31 and the back surface of the panel component member main body 3 becomes smaller, sink marks due to a difference in thermal shrinkage are less likely to occur on the surface of the panel component member main body 3 at the time of molding, and the appearance can be improved.

さらに、後述するエアバッグ３３の展開圧力による第２脆弱部１３の破断力がパネル構成部材本体３に作用しても、パネル構成部材本体３が変形したり破損したりすることなく安定してヒンジ部１５の根本を支持し、エアバッグ３３の展開性能にばらつきを生じさせることがない。また、第２脆弱部１３の破断する勢いが剛性リブ部３１で止まり必要以上に第２脆弱部１３から連続してパネル構成部材本体３に亀裂が生じたりすることがない。   Further, even if the breaking force of the second fragile portion 13 due to the deployment pressure of the airbag 33 to be described later acts on the panel component member body 3, the panel component member body 3 is stably hinged without being deformed or damaged. The root of the portion 15 is supported, and the deployment performance of the airbag 33 does not vary. Further, the moment of breaking of the second fragile portion 13 stops at the rigid rib portion 31, and the panel constituent member body 3 is not cracked continuously from the second fragile portion 13 more than necessary.

上記パネル構成部材本体３裏面には、折り畳まれたエアバッグ３３（図４に展開状態を示す）やインフレータ（図示せず）等を収容してなるエアバッグ装置３５がエアバッグドア部９裏面に対応するように配置され、該エアバッグ装置３５の底面には第１ブラケット３７が溶接されている。一方、車幅方向に延びてインストルメントパネルを支持する固定側であるインパネレインフォースメント３９には第２ブラケット４１の一端が溶接され、該第２ブラケット４１の他端は、上記第１ブラケット３７にボルト４３とナット４５とで締結されている。これにより、上記エアバッグ装置３５がインパネレインフォースメント３９に第１及び第２ブラケット３７，４１を介して連結支持されている。   On the back surface of the panel component member body 3, an airbag device 35 containing a folded airbag 33 (shown in a deployed state in FIG. 4), an inflator (not shown), and the like is provided on the back surface of the airbag door portion 9. The first bracket 37 is welded to the bottom surface of the airbag device 35. On the other hand, one end of the second bracket 41 is welded to the instrument panel reinforcement 39 that is a fixed side that extends in the vehicle width direction and supports the instrument panel, and the other end of the second bracket 41 is connected to the first bracket 37. The bolt 43 and the nut 45 are fastened. Thus, the airbag device 35 is connected and supported to the instrument panel reinforcement 39 via the first and second brackets 37 and 41.

上記エアバッグ装置３５の略上半部分には、平面視略矩形状の金属製ブラケット部材４７が外嵌合されて固定されている。該ブラケット部材４７は、車幅方向に延びる前壁部４９及び後壁部５１と、これら前壁部４９及び後壁部５１の両端同士を連結する車体前後方向に延びる両側壁部５３とで構成されている。上記前壁部４９の上端にはネジ挿通孔５５ａを有する取付片部５５が４個下方に折曲形成されているとともに、上記両側壁部５３の上端にもネジ挿通孔５５ａを有する取付片部５５が２個ずつ下方に折曲形成されている。上記後壁部５１の上端には折曲板部５７が全幅に亘って下方に折曲形成され、該折曲板部５７の下端縁には係止片部５７ａが車幅方向に間隔をあけて５個側方に突出するように折曲形成されている。そして、これら係止片部５７ａを上記係止壁部１７の各係止孔１７ａに挿入してエアバッグ３３の展開圧力がエアバッグドア部９に作用した際、エアバッグドア部９の車体後方端縁側のパネル構成部材本体３が押出方向に撓むことで各係止孔１７ａに係止させるようになっている。また、ブラケット部材４７の前壁部４９，後壁部５１及び両側壁部５３の上端には、パネル構成部材本体３の裏面に接するか、または近接する上端平面部４９ｂ，５１ｂ，５３ｂが第１破断溝部５と対向する位置に形成されており、パネル構成部材本体３の表側より作用する押圧力に対して第１破断溝部５を支持し、第１脆弱部７が不用意に破断しないようにしている。   A metal bracket member 47 having a substantially rectangular shape in plan view is fitted and fixed to a substantially upper half portion of the airbag device 35. The bracket member 47 includes a front wall portion 49 and a rear wall portion 51 that extend in the vehicle width direction, and both side wall portions 53 that extend in the vehicle body front-rear direction connecting both ends of the front wall portion 49 and the rear wall portion 51. Has been. At the upper end of the front wall portion 49, four attachment piece portions 55 having screw insertion holes 55 a are bent downward, and the attachment piece portion having screw insertion holes 55 a also at the upper ends of the side wall portions 53. 55 is bent downward by two. A bent plate portion 57 is bent downward at the upper end of the rear wall portion 51 over the entire width, and a locking piece portion 57a is spaced from the lower end edge of the bent plate portion 57 in the vehicle width direction. Are bent so as to protrude sideways. Then, when these locking pieces 57a are inserted into the locking holes 17a of the locking wall 17 and the deployment pressure of the airbag 33 acts on the airbag door 9, the rear side of the airbag door 9 in the vehicle body The panel constituent member body 3 on the edge side is bent in the pushing direction so as to be locked in the locking holes 17a. Further, upper end flat portions 49b, 51b, and 53b that are in contact with or close to the back surface of the panel constituting member main body 3 are formed on the upper ends of the front wall portion 49, the rear wall portion 51, and the both side wall portions 53 of the bracket member 47, respectively. It is formed at a position facing the breaking groove 5 and supports the first breaking groove 5 against the pressing force acting from the front side of the panel component main body 3 so that the first fragile portion 7 does not break carelessly. ing.

一方、上記前壁部４９の上端平面部４９ｂには、スリット状の係合孔４９ａがエアバッグドア部９の車体前方端縁に沿うように２個形成され、上記各突起部２７が各係合孔４９ａに挿入されて上記ブラケット部材４７と係合している。この係合状態で、上記前壁部４９の各取付片部５５は、上記各取付ボス部２３にあてがわれてネジ５９をネジ挿通孔５５ａを経て各取付ボス部２３のネジ穴にねじ込むにより締結される。また、上記両側壁部５５側の各取付片部５５も、図示しないが、上記第１脆弱部形成領域Ａ１の車幅方向両外側近傍の各取付ボス部２９にあてがわれてネジをネジ挿通孔５５ａを経て各取付ボス部２９のネジ穴にねじ込むにより締結される。これにより、エアバッグ装置３５をブラケット部材４７を介して各取付ボス部２３，２９に取り付けるようにしている。これら締結に際しては、上記ブラケット部材４７の係止片部５７ａを係止壁部１７の係止孔１７ａに挿入するとともに、各突起部２７を各係合孔４９ａに挿入することで、エアバッグ装置３５をパネル構成部材本体３に対して位置決めする。そして、この取付状態で、上記ブラケット部材４７は、エアバッグ装置３５のヒンジ部１５側全幅を含む全周に亘って第１脆弱部７よりも内側寄りのエアバッグドア部９裏面に向けて延び、エアバッグ装置３５の作動により展開するエアバッグ３３をエアバッグドア部９裏面に導くガイドプレートを兼ねている。   On the other hand, two slit-like engagement holes 49a are formed in the upper end flat portion 49b of the front wall portion 49 so as to be along the vehicle body front edge of the airbag door portion 9, and the protrusions 27 are connected to the engagement portions 49a. It is inserted into the joint hole 49a and engaged with the bracket member 47. In this engaged state, each mounting piece portion 55 of the front wall portion 49 is applied to each mounting boss portion 23 and screwed into the screw hole of each mounting boss portion 23 through the screw insertion hole 55a. It is concluded. Further, although not shown in the drawings, the attachment piece portions 55 on the both side wall portions 55 side are also applied to the attachment boss portions 29 in the vicinity of both outer sides in the vehicle width direction of the first fragile portion forming region A1, and screws are inserted through the screws. Fastening is performed by screwing into the screw holes of the mounting boss portions 29 through the holes 55a. Thereby, the airbag device 35 is attached to the attachment boss portions 23 and 29 via the bracket member 47. At the time of these fastenings, the airbag device is formed by inserting the locking piece portion 57a of the bracket member 47 into the locking hole 17a of the locking wall portion 17 and inserting the protrusions 27 into the engaging holes 49a. 35 is positioned with respect to the panel member main body 3. In this attached state, the bracket member 47 extends toward the back surface of the airbag door 9 closer to the inner side than the first fragile portion 7 over the entire circumference including the entire width of the hinge device 15 side of the airbag device 35. Also, it serves as a guide plate that guides the airbag 33 that is deployed by the operation of the airbag device 35 to the back surface of the airbag door portion 9.

上述の如く構成されたパネル構成部材１では、車両が衝突すると、エアバッグ装置３５のエアバッグ３３がインフレータの作動によって膨張してブラケット部材４７にガイドされながら展開し、その展開圧力でエアバッグドア部９が上方に押圧されて第１脆弱部７及び第２脆弱部１３が破断することにより、図４に示すように、エアバッグドア部９はヒンジ部１５の一端に一体に接続された状態でパネル構成部材本体３と切り離されて開くとともに、上記ヒンジ部１５は他端がパネル構成部材本体３に一体に接続された状態で非ヒンジ部１９と切り離されて湾曲変形しながらパネル構成部材本体３から起き上がる。これにより、エアバッグドア部９がヒンジ部１５の他端を支点として回動して車体前方上向きに開き、展開したエアバッグ３３で助手席の乗員を車体前後方向の衝撃から保護するようになっている。   In the panel component 1 configured as described above, when the vehicle collides, the airbag 33 of the airbag device 35 is inflated by the operation of the inflator and is deployed while being guided by the bracket member 47, and the airbag door is developed by the deployment pressure. When the portion 9 is pressed upward and the first fragile portion 7 and the second fragile portion 13 are broken, the airbag door portion 9 is integrally connected to one end of the hinge portion 15 as shown in FIG. The panel component member main body 3 is opened while being separated from the panel component member main body 3 while the other end of the hinge portion 15 is integrally connected to the panel component member main body 3 and is separated from the non-hinge portion 19 while being bent and deformed. Get up from 3. As a result, the airbag door 9 pivots about the other end of the hinge portion 15 and opens upward in the front of the vehicle body, and the deployed airbag 33 protects the passenger in the front passenger seat from impacts in the longitudinal direction of the vehicle body. ing.

このように、エアバッグドア部９が開く際、非ヒンジ部１９を各取付ボス部２３、ブラケット部材４７及びエアバッグ装置３５を介してインパネレインフォースメント３９に支持しているので、非ヒンジ部１９をエアバッグドア部９の開動作及びヒンジ部１５の起き上がり動作に影響されることなく定位置に固定でき、第２脆弱部１３を速やかに破断することができる。しかも、ヒンジ部１５は連続せずにエアバッグドア部９の車体前方端縁に沿って間隔をあけて複数形成されて回動抵抗が少なくなっている。したがって、エアバッグドア部９を確実に開くことができる。特に、上記ブラケット部材４７と非ヒンジ部２１の突起部２７とが係合しているので、エアバッグドア部９開時に、ヒンジ部１５の起き上がり動作に伴う引き上げ力が非ヒンジ部２１に作用しても、該非ヒンジ部２１はこの引き上げ力に十分に抗して安定した不動状態を確保でき、ヒンジ部１５を非ヒンジ部２１から確実に切り離してエアバッグドア部９の開動作を安定させてエアバッグドア部９の展開性能を高めることができる。この際、突起部２７をブラケット部材４７の係合孔４９ａに挿入してヒンジ部１５の引き上げ力に抗しているので、ブラケット部材４７と突起部２７との係合を確実に行うことができる。   Thus, when the airbag door 9 is opened, the non-hinge portion 19 is supported by the instrument panel reinforcement 39 via the mounting boss portions 23, the bracket member 47, and the airbag device 35. 19 can be fixed at a fixed position without being affected by the opening operation of the airbag door portion 9 and the raising operation of the hinge portion 15, and the second fragile portion 13 can be quickly broken. Moreover, the hinge portion 15 is not continuous but is formed in plural along the front end edge of the vehicle body of the airbag door portion 9 so as to reduce the rotational resistance. Therefore, the airbag door part 9 can be opened reliably. In particular, since the bracket member 47 and the projection 27 of the non-hinge portion 21 are engaged, the lifting force associated with the raising operation of the hinge portion 15 acts on the non-hinge portion 21 when the airbag door portion 9 is opened. However, the non-hinge part 21 can sufficiently resist the pulling force and secure a stable immobilization state, and the hinge part 15 can be reliably separated from the non-hinge part 21 to stabilize the opening operation of the airbag door part 9. The deployment performance of the airbag door part 9 can be improved. At this time, since the protruding portion 27 is inserted into the engagement hole 49a of the bracket member 47 and resists the pulling force of the hinge portion 15, the bracket member 47 and the protruding portion 27 can be reliably engaged. .

また、上記ヒンジ部１５を湾曲変形可能な板状に形成しているので、エアバッグドア部９開時にヒンジ部１５を起き上がらせながら弧状に湾曲変形させてエアバッグ３３の展開圧力を効果的に吸収することができる。これにより、エアバッグドア部９にエアバッグ３３の展開圧力が過剰に作用しないようにすることができるとともに、ヒンジ部１５を千切れないようにすることができ、エアバッグドア部９の飛散を防止することができる。   Further, since the hinge portion 15 is formed in a plate shape that can be bent and deformed, when the airbag door portion 9 is opened, the hinge portion 15 is raised and curved and deformed in an arc shape, thereby effectively expanding the deployment pressure of the airbag 33. Can be absorbed. As a result, the deployment pressure of the airbag 33 can be prevented from acting excessively on the airbag door portion 9, and the hinge portion 15 can be prevented from being broken, thereby preventing the airbag door portion 9 from being scattered. Can be prevented.

さらに、エアバッグドア部９をパネル構成部材本体３の一部で構成しているので、特許文献１のような高価な熱可塑性エラストマー材でエアバッグドア部を成形する場合や、特許文献２のようなフラップ部をエアバッグドア部の裏面に溶着する場合に比べて廉価なパネル構成部材１とすることができる。   Furthermore, since the airbag door part 9 is comprised by a part of panel structural member main body 3, when shape | molding an airbag door part with an expensive thermoplastic elastomer material like patent document 1, or patent document 2 Compared with the case where such a flap portion is welded to the back surface of the airbag door portion, the panel component 1 can be made inexpensive.

さらにまた、ブラケット部材４７がエアバッグ３３をエアバッグドア部９裏面に導くガイドプレートを兼ねているので、別途にガイドプレートを設ける場合に比べて部品点数を削減することができる。   Furthermore, since the bracket member 47 also serves as a guide plate that guides the airbag 33 to the back surface of the airbag door portion 9, the number of parts can be reduced as compared with a case where a guide plate is separately provided.

さらに、取付ボス部２３をパネル構成部材本体３裏面に突設するだけで、成形時にアンダーカット部ができず、スライド型を用いずに簡単にエアバッグ装置３５を取り付ける取付部を成形することができる。   Furthermore, by simply projecting the mounting boss 23 on the back surface of the panel component member body 3, an undercut portion cannot be formed at the time of molding, and the mounting portion for mounting the airbag device 35 can be easily molded without using a slide mold. it can.

さらにまた、エアバッグ３３の展開圧力でエアバッグドア部９に開方向への押出力が作用した際、ブラケット部材４７の係止片部５７ａを係止壁部１７の係止孔１７ａに係止させることで、パネル構成部材本体３が押出方向に動くのを規制することができる。したがって、その後、エアバッグドア部９が開いてもパネル構成部材本体３をその動作に影響されることなく動かないようにでき、第１脆弱部７を速やかに破断してエアバッグドア部９の展開性能を向上させることができる。また、上記ブラケット部材４７の係止片部５７ａを係止壁部１７の係止孔１７ａに挿入してエアバッグ装置３５を仮止めした状態で、エアバッグ装置３５をブラケット部材４７を介してパネル構成部材本体３裏面の取付ボス部２３に取り付けるので、エアバッグ装置３５の取付作業を容易に行うことができる。   Furthermore, when a pushing force in the opening direction is applied to the airbag door portion 9 by the deployment pressure of the airbag 33, the locking piece portion 57a of the bracket member 47 is locked to the locking hole 17a of the locking wall portion 17. By doing, it can control that panel constituent member main part 3 moves to the extrusion direction. Therefore, even if the airbag door portion 9 is subsequently opened, the panel component member main body 3 can be prevented from moving without being affected by the operation thereof, and the first fragile portion 7 can be quickly broken to remove the airbag door portion 9. Deployment performance can be improved. Further, in a state where the locking piece portion 57a of the bracket member 47 is inserted into the locking hole 17a of the locking wall portion 17 and the airbag device 35 is temporarily fixed, the airbag device 35 is connected to the panel via the bracket member 47. Since it attaches to the attachment boss | hub part 23 of the structural member main body 3, the attachment operation | work of the airbag apparatus 35 can be performed easily.
