Description

本発明は、車両に搭載されるエアバッグ装置に係り、エアバッグ展開時における隣接部品の損傷等を防止する技術に関する。   The present invention relates to an airbag device mounted on a vehicle, and relates to a technique for preventing damage to adjacent components when the airbag is deployed.

近年の自動車では、衝突の際に車体と乗員との間にエアバッグを展開させ、乗員を衝撃から保護するエアバッグ装置が搭載されている。エアバッグ装置としては、ステアリングホイールやインストルメントパネル等に組み込まれ、前方衝突時に後方に展開するものが主流であるが、ルーフレールとルーフライニング側縁との間に設置され、側方衝突時に下方に展開するサイドカーテン式のものも出現している。サイドカーテン式のエアバッグ装置では、展開を下方に規制する必要があるため、エアバッグは下方が開放されたカバー部材に収容された状態でルーフレールに固定される(特許文献1参照)。   In recent automobiles, an airbag device is installed that deploys an airbag between a vehicle body and an occupant in the event of a collision and protects the occupant from impact. Airbag devices are mainly built into steering wheels, instrument panels, etc., and are deployed rearward at the time of a frontal collision, but are installed between the roof rail and the roof lining side edge, and are lowered at the time of a side collision. A side curtain type has also emerged. In the side curtain type airbag device, since the deployment needs to be restricted downward, the airbag is fixed to the roof rail in a state of being accommodated in a cover member that is open at the bottom (see Patent Document 1).

ところで、サイドカーテン式のエアバッグ装置では、設置部位の近傍に隣接部品(ワイヤハーネスやドレインホース等)が配索あるいは配管されることが多い。そこで、特許文献1のエアバッグ装置では、コ字断面形状を呈するカバー部材の車室内側壁に副取り付け部を形成し、隣接部品に固着された副取り付け片をこの副取り付け部に固定することで、隣接部品の組付容易化や組付安定性、組付精度等の向上を図っている。   By the way, in a side curtain type airbag apparatus, adjacent parts (wire harness, drain hose, etc.) are often routed or piped in the vicinity of the installation site. Therefore, in the airbag device of Patent Document 1, a sub-attachment portion is formed on the side wall of the interior of the cover member having a U-shaped cross-section, and the sub-attachment piece fixed to the adjacent part is fixed to the sub-attachment portion. In addition, it facilitates the assembly of adjacent parts, improves the stability of assembly, and improves the accuracy of assembly.

しかしながら、上述した特許文献1による隣接部品の固定方法を採用した場合、可撓性を有するカバー部材の車室内側壁に固定されるため、エアバッグ展開時には多少なりとも隣接部品が変形あるいは損傷してしまい、修理の際に部品交換を余儀なくされることがあった。また、副取り付け片を隣接部品に設ける都合上、隣接部品の構成部品点数や製造コストが増大することも避けられなかった。   However, when the fixing method of the adjacent part by patent document 1 mentioned above is employ | adopted, since it fixes to the vehicle interior side wall of a flexible cover member, an adjacent part may be deformed or damaged to some extent at the time of airbag deployment. In other words, parts were sometimes replaced during repairs. In addition, for the convenience of providing the sub-attachment piece on the adjacent part, it is inevitable that the number of components of the adjacent part and the manufacturing cost increase.

本発明は、上記状況に鑑みなされたものであり、隣接部品のエアバッグ展開時における変形抑制や製造コストの低減等を実現したエアバッグ装置を提供することを目的とする。   The present invention has been made in view of the above situation, and an object of the present invention is to provide an airbag device that realizes suppression of deformation at the time of airbag deployment of adjacent parts, reduction of manufacturing costs, and the like.

第1の発明は、乗員と車体との間で下方に展開するエアバッグと、前記車体に取り付けられ、当該エアバッグを折り畳んだ状態で保持するカバー部材とを備えたエアバッグ装置であって、前記カバー部材の上面に隣接部品が配設されることを特徴とする。   A first invention is an airbag device including an airbag that is deployed downward between an occupant and a vehicle body, and a cover member that is attached to the vehicle body and holds the airbag in a folded state. Adjacent parts are disposed on the upper surface of the cover member.

また、第2の発明は、第1の発明に係るエアバッグ装置において、前記カバー部材の上面に前記隣接部品を保持する保持手段が一体成形されたことを特徴とする。   According to a second aspect of the present invention, in the airbag apparatus according to the first aspect of the present invention, holding means for holding the adjacent part is integrally formed on the upper surface of the cover member.

第1の発明によれば、隣接部品は、エアバッグ展開時における変形が最も少ないカバー部材の上部に配設されるため、エアバッグ展開時にも変形や損傷が生じ難くなる。また、第2の発明によれば、副取り付け片等を設ける必要がなくなるため、隣接部品の製造コストを低減させることができる。   According to the first aspect, since the adjacent component is disposed on the upper part of the cover member that is least deformed when the airbag is deployed, deformation and damage are less likely to occur when the airbag is deployed. Further, according to the second invention, it is not necessary to provide a sub-mounting piece or the like, so that the manufacturing cost of the adjacent parts can be reduced.

以下、本発明の一実施形態について図面を参照しながら説明する。
図1は本発明に係るエアバッグ装置を搭載した自動車の運転席を示す斜視図であり、図2は本発明に係るエアバッグ装置の要部を示す斜視図であり、図3は図2中のIII−III断面図である。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a driver's seat of an automobile equipped with an airbag apparatus according to the present invention, FIG. 2 is a perspective view showing a main part of the airbag apparatus according to the present invention, and FIG. It is III-III sectional drawing.

図1〜図3に示すように、自動車1にはルーフライニング2(図2には示さず)の側縁とルーフレール3(図1,図2には示さず)との間にサイドカーテン式のエアバッグ装置4が設置されている。エアバッグ装置4は、円柱状に折り畳まれたエアバッグ5と、エアバッグ5を保持する前部カバー部材6および後部カバー部材7とを有している。前後部カバー部材6,7は、樹脂を素材とする射出成型品であり、ルーフレール3への取付ブラケットを兼ねるとともに、エアバッグ5の展開方向を下方に規制すべくその下方が開放されている。図2中の符号8は、エアバッグ5を前後部カバー部材6,7に固定するテープであり、エアバッグ5の展開時には容易に破断する。エアバッグ5は、自動車1の側方衝突時等において、乗員(運転者)とサイドウインドウ10(車体)との間で下方に展開し、乗員の頭部に加わる衝撃を緩和する。図3中に符号15で示す部材はドアシールラバーであり、ルーフライニング2の側端部を係止している。   As shown in FIGS. 1 to 3, the automobile 1 has a side curtain type between a side edge of a roof lining 2 (not shown in FIG. 2) and a roof rail 3 (not shown in FIGS. 1 and 2). An airbag device 4 is installed. The airbag device 4 includes an airbag 5 folded in a columnar shape, and a front cover member 6 and a rear cover member 7 that hold the airbag 5. The front and rear cover members 6 and 7 are injection-molded products made of resin. The front and rear cover members 6 and 7 also serve as mounting brackets for the roof rail 3 and open below to restrict the deployment direction of the airbag 5 downward. Reference numeral 8 in FIG. 2 is a tape for fixing the airbag 5 to the front and rear cover members 6 and 7 and is easily broken when the airbag 5 is deployed. The airbag 5 is deployed downward between the occupant (driver) and the side window 10 (vehicle body) at the time of a side collision of the automobile 1 to alleviate the impact applied to the occupant's head. A member denoted by reference numeral 15 in FIG. 3 is a door seal rubber, and locks a side end portion of the roof lining 2.

本実施形態の場合、エアバッグ5の上方には、隣接部品であるワイヤハーネス11が配索されている。ワイヤハーネス11は、エアバッグ装置4のインフレータ(図示せず)やサンルーフ装置等への電力供給を行う電線を結束したものであり、コネクタ12やプロテクタ13,14を有している。後部カバー部材7の上部にはハーネスクリップ9(保持手段)が一体成形されており、ワイヤハーネス11がこのハーネスクリップ9に保持/固定されている。ハーネスクリップ9は車室側に挿入口9aを有しており、ワイヤハーネス11は、この挿入口9aからワンタッチでハーネスクリップ9内に挿入される。   In the case of this embodiment, the wire harness 11 which is an adjacent part is routed above the airbag 5. The wire harness 11 is a bundle of electric wires for supplying power to an inflator (not shown) of the airbag device 4, a sunroof device, and the like, and includes a connector 12 and protectors 13 and 14. A harness clip 9 (holding means) is integrally formed on the upper portion of the rear cover member 7, and the wire harness 11 is held / fixed to the harness clip 9. The harness clip 9 has an insertion port 9a on the vehicle compartment side, and the wire harness 11 is inserted into the harness clip 9 from the insertion port 9a with one touch.

本実施形態では、このような構成を採ったことにより、自動車1の製造時においては、エアバッグ装置4をルーフレール3に締結した後、ワイヤハーネス11を挿入口9aからハーネスクリップ9内に挿入することで、ワイヤハーネス11が容易に正規の位置に固定される。また、自動車1が他の車両や障害物に衝突し、図4に示すように、エアバッグ5がルーフライニング2の下部を押し開いて下方に展開しても、変形し難い前後部カバー部材6,7の上方にワイヤハーネス11が配索されているため、ワイヤハーネス11の変形や損傷等を防止することが可能となる。また、ハーネスクリップ9は、後部カバー部材7に一体成形されているため、エアバッグ装置4やワイヤハーネス11の構成部品が増加せず、加工工数や製造コストが低減される。   In the present embodiment, by adopting such a configuration, when the automobile 1 is manufactured, after the airbag device 4 is fastened to the roof rail 3, the wire harness 11 is inserted into the harness clip 9 from the insertion port 9a. As a result, the wire harness 11 is easily fixed at the proper position. Moreover, even if the automobile 1 collides with another vehicle or an obstacle, and the airbag 5 pushes the lower part of the roof lining 2 and deploys downward as shown in FIG. , 7, the wire harness 11 is routed, so that the wire harness 11 can be prevented from being deformed or damaged. Further, since the harness clip 9 is integrally formed with the rear cover member 7, the number of components of the airbag device 4 and the wire harness 11 does not increase, and the processing man-hours and manufacturing costs are reduced.

以上で具体的実施形態の説明を終えるが、本発明の態様は上記実施形態に限られるものではない。例えば、上記実施形態は運転席側のサイドカーテン式のエアバッグ装置に本発明を適用したものであるが、助手席や後席側のサイドカーテン式のエアバッグ装置やリヤウインドカーテン式のエアバッグ装置等にも当然に適用可能である。また、上記実施形態では隣接部品としてワイヤハーネスを挙げたが、隣接部品はサンルーフ装置のドレインホース等であってもよい。また、上記実施形態では保持手段として後部カバー部材に一体成形されたハーネスクリップを採用したが、保持手段は、別体の樹脂クリップやワイヤハーネス等に一体化されたクリップ等であったもよい。その他、自動車やエアバッグ装置の具体的構成等についても、本発明の趣旨を逸脱しない範囲であれば適宜変更可能である。   Although description of specific embodiment is finished above, the aspect of the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the present invention is applied to the side curtain type airbag device on the driver's seat side, but the side curtain type airbag device or the rear wind curtain type airbag on the passenger seat or the rear seat side. Of course, the present invention can also be applied to devices and the like. Moreover, although the wire harness was mentioned as an adjacent component in the said embodiment, the adjacent component may be a drain hose etc. of a sunroof apparatus. In the above embodiment, the harness clip integrally formed on the rear cover member is used as the holding means. However, the holding means may be a separate resin clip, a clip integrated with a wire harness, or the like.
