JP 2001-315599 A

しかし、従来の歩行者保護装置では、歩行者の一次衝突時における車両との干渉をエアバッグで保護することができるものの、一次衝突後の歩行者の路面側への落下を防止する点に、改善の余地があった。   However, in the conventional pedestrian protection device, although it is possible to protect the interference with the vehicle at the time of the primary collision of the pedestrian with an airbag, in order to prevent the pedestrian from falling to the road surface side after the primary collision, There was room for improvement.

本発明は、上述の課題を解決するものであり、一次衝突時の歩行者を保護可能とし、さらに、一次衝突後の歩行者の路面側への落下を防止可能な歩行者保護装置を提供することを目的とする。   The present invention solves the above-described problems, and provides a pedestrian protection device capable of protecting a pedestrian at the time of a primary collision and further capable of preventing a pedestrian from falling to the road surface after the primary collision. For the purpose.

本発明に係る歩行者保護装置は、車両に搭載されて、一次衝突時の歩行者を保護可能とし、さらに、一次衝突後の歩行者の路面側への落下を防止可能な歩行者保護装置であって、
車両の前面側におけるフロントバンパ付近からフードパネルの高さを越える上方まで展開膨張して、車両の幅寸法と略等しい幅寸法を有して、膨張を完了させるエアバッグを備え、
エアバッグが、膨張完了時に前後方向に貫通して、歩行者の身体部位を係止可能な複数の係止孔を備えて、構成されていることを特徴とする。 The pedestrian protection device according to the present invention is a pedestrian protection device that is mounted on a vehicle, can protect a pedestrian at the time of a primary collision, and can prevent a pedestrian from falling to the road surface after the primary collision. There,
An airbag that is deployed and inflated from near the front bumper on the front side of the vehicle to above the height of the hood panel, has a width dimension substantially equal to the width dimension of the vehicle, and completes the inflation,
The airbag includes a plurality of locking holes that pass through in the front-rear direction when the inflation is completed and can lock the body part of the pedestrian.

本発明に係る歩行者保護装置では、エアバッグが展開膨張を完了させれば、車両の前面側におけるフロントバンパ付近からフードパネルの高さを越える上方まで、車両の幅寸法と略等しい幅寸法を有して、エアバッグが配設されることから、一次衝突時の車両に干渉しようとする歩行者を、クッション作用を奏して、エアバッグが保護できる。   In the pedestrian protection device according to the present invention, when the airbag has been deployed and inflated, the width dimension is substantially equal to the width dimension of the vehicle from near the front bumper on the front side of the vehicle to above the height of the hood panel. Thus, since the airbag is disposed, the airbag can be protected by cushioning a pedestrian who tries to interfere with the vehicle at the time of the primary collision.

そして、展開膨張を完了させたエアバッグは、前後方向に貫通して、歩行者の身体部位を係止可能な複数の係止孔を備えて、構成されていることから、歩行者の腕等が係止孔に挿入されて係止されれば、歩行者は、係止孔の周縁に引っ掛る状態で、路面側への落下が防止され、路面からのダメージを受けない。   And since the airbag which completed the expansion | deployment is penetrated in the front-back direction and is provided with the some locking hole which can lock a pedestrian's body part, a pedestrian's arm etc. If is inserted into the locking hole and locked, the pedestrian is prevented from falling to the road surface while being caught on the periphery of the locking hole, and is not damaged by the road surface.

したがって、本発明に係る歩行者保護装置では、一次衝突時の歩行者を保護でき、さらに、一次衝突後の歩行者の路面側への落下を防止することもできる。   Therefore, the pedestrian protection device according to the present invention can protect the pedestrian at the time of the primary collision, and can also prevent the pedestrian from falling to the road surface after the primary collision.

そして、展開膨張完了時のエアバッグは、前面側を、車両後方側に凹ませるような凹面として、形成することが望ましい。   Then, it is desirable to form the airbag at the time of completion of deployment as a concave surface in which the front side is recessed toward the vehicle rear side.

このように構成されていれば、一次衝突時のエアバッグの前面側で、歩行者が拘束されれば、凹面のより凹んだ側に案内され易く、係止孔に対して、歩行者の腕等の一部を深く侵入させる、あるいは、当初、係止孔に係止されていなくとも、係止孔に侵入させる事態を招き易く、一層、一次衝突後の歩行者の路面側への落下を防止することもできる。   If comprised in this way, if a pedestrian is restrained by the front side of the airbag at the time of a primary collision, it will be easy to be guided to the more concave side of a concave surface, and a pedestrian's arm will be with respect to a locking hole. Or even if it is not locked in the locking hole at the beginning, it is easy to cause a situation of entering the locking hole. It can also be prevented.

以下、本発明の一実施形態を図面に基づいて説明する。なお、本明細書では、前後の方向は、車両の前後方向に沿う方向を、基準とし、左右の方向は、車両の後方側から前方側を見た際の左右の方向に沿う方向を、基準とする。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Further, the case 25 is disposed in the vicinity of the center of the vehicle V in the left-right direction so that the width in the left-right direction is slightly smaller than the distance between the left and right headlamps 7, 7 of the vehicle V (FIG. 1). 3). In addition, the member of the code | symbol 2 shown in FIG. 2 is the side member 2 which connected the reinforcement 3 to the front end.

インフレーター２１は、既述したように、制御装置１１によって作動を制御され、さらに、図３に示すように、複数のガス吐出口２１ａを備えた円柱状として、ボルト２２ａを突設させた円環状の複数の取付ブラケット２２に、保持されている。インフレーター２１は、エアバッグ１４内に収納された状態で、各ブラケット２２のボルト２２ａを、エアバッグ１４とケース２５とに貫通させて、ナット２３止めすることにより、エアバッグ１４とともに、ケース２５に固定されている。   As described above, the operation of the inflator 21 is controlled by the control device 11, and, as shown in FIG. Are held by a plurality of mounting brackets 22. The inflator 21 is accommodated in the case 25 together with the airbag 14 by passing the bolts 22a of the respective brackets 22 through the airbag 14 and the case 25 and fixing the nuts 23 while being accommodated in the airbag 14. It is fixed.

エアバッグ１４は、図１〜５に示すように、内部にインフレーター２１を収納した状態で、折り畳まれてケース２５内に収納されている。そして、エアバッグ１４は、膨張完了時の状態で、車両Ｖの前面側におけるフロントバンパ４付近からフードパネル９の高さを越える上方まで展開膨張する略板形状として、車両Ｖの幅寸法と略等しい幅寸法を有して、略板形状に膨張を完了させるように、構成されている。   As shown in FIGS. 1 to 5, the airbag 14 is folded and stored in the case 25 with the inflator 21 stored therein. The airbag 14 is substantially in the form of a plate that expands and expands from the vicinity of the front bumper 4 on the front side of the vehicle V to the upper side exceeding the height of the hood panel 9 when the inflation is completed. It has an equal width dimension and is configured to complete the expansion into a substantially plate shape.

このエアバッグ１４は、可撓性を有したポリエステル等の織布から形成される袋状として、膨張完了時の下部側に、インフレーター２１を内蔵させて、フロントバンパ４の上方で左右方向に延びるように膨張を完了させる基部１５を配設させて構成されるともに、基部１５には、左右方向に沿って並設されるように上方に延びるように膨張を完了させる複数の縦棒部１６が連通され、さらに、各縦棒部１６の上端が、相互に連結されるように、左右方向の延びる上連結部１８に連通されている。なお、実施形態の場合には、膨張を完了させた基部１５は、図５に示すように、後部１５ａが、フードパネル９の前部９ａより上方に位置して、前部９ａの上面側で支持されるように、構成されている。   The airbag 14 is formed as a bag formed of a flexible woven fabric such as polyester, and has an inflator 21 built in on the lower side when inflation is completed, and extends in the left-right direction above the front bumper 4. A plurality of vertical bar portions 16 for completing expansion so as to extend upward so as to be arranged side by side in the left-right direction are configured. Further, the upper ends of the vertical bar portions 16 are communicated with the upper connecting portion 18 extending in the left-right direction so as to be connected to each other. In the case of the embodiment, as shown in FIG. 5, the base portion 15 that has completed the expansion has a rear portion 15 a positioned above the front portion 9 a of the hood panel 9, and on the upper surface side of the front portion 9 a. It is configured to be supported.

そして、各縦棒部１６は、図４〜６に示すように、膨張完了時のエアバッグ１４の前面側に、上下方向や水平方向の断面で、後方側に凹んだ凹面１９を形成可能に、水平方向の膜長に関し、上・下端部１６ａ・１６ｂから上下方向の中間部１６ｃに向かうにつれて、徐々に小さくなるように、設定されている。また、各縦棒部１６間の水平方向の開口幅を狭くして上下方向に延びた隙間ｈが、膨張完了時に前後方向に貫通して、歩行者Ｗの身体部位Ａを係止可能な係止孔１７を形成するように、各縦棒部１６の水平方向の膜長が、設定されている。   And each vertical bar | burr part 16 can form the concave surface 19 dented in the back side by the cross section of an up-down direction or a horizontal direction in the front side of the airbag 14 at the time of completion of inflation, as shown in FIGS. The film length in the horizontal direction is set so as to gradually decrease from the upper and lower end portions 16a and 16b toward the intermediate portion 16c in the vertical direction. Further, a gap h extending in the vertical direction by narrowing the horizontal opening width between the vertical bar portions 16 penetrates in the front-rear direction when the expansion is completed, and can engage the body part A of the pedestrian W. The film length in the horizontal direction of each vertical bar portion 16 is set so as to form the stop hole 17.

この歩行者保護装置Ｓでは、車両Ｖに搭載された状態で、制御装置１１が、センサ１２からの信号により、歩行者Ｗとの一次衝突を予知した際には、インフレーター２１を作動させ、ガス吐出口２１ａから膨張用ガスを吐出させることから、エアバッグ１４が、カバー材２８の扉部２９を押し開いてケース２５の開口２５ａから上々へ突出して、膨張することとなる。   In this pedestrian protection device S, when the control device 11 predicts a primary collision with the pedestrian W by a signal from the sensor 12 in a state where it is mounted on the vehicle V, the inflator 21 is operated, Since the inflation gas is discharged from the discharge port 21a, the air bag 14 pushes open the door portion 29 of the cover material 28 and protrudes upward from the opening 25a of the case 25 to be inflated.

そして、実施形態の歩行者保護装置Ｓでは、図４〜６に示すように、エアバッグ１４が展開膨張を完了させれば、車両Ｖの前面側におけるフロントバンパ４付近からフードパネル９の高さを越える上方まで、車両Ｖの幅寸法と略等しい幅寸法を有して、エアバッグ１４が配設されることから、一次衝突時の車両Ａに干渉しようとする歩行者Ｗを、クッション作用を奏して、エアバッグ１４が保護できる。   And in the pedestrian protection apparatus S of embodiment, as shown in FIGS. 4-6, if the airbag 14 completes expansion | deployment inflation, the height of the hood panel 9 from the front bumper 4 vicinity in the front side of the vehicle V will be shown. Since the airbag 14 has a width dimension substantially equal to the width dimension of the vehicle V and exceeds the upper limit, the pedestrian W who tries to interfere with the vehicle A at the time of the primary collision is cushioned. The airbag 14 can be protected.

そして、展開膨張を完了させたエアバッグ１４は、前後方向に貫通して、歩行者Ｗの腕Ｗ等の身体部位を係止可能な複数の係止孔１７を備えて、構成されていることから、歩行者Ｗの腕Ａ等が係止孔１７に挿入されて係止されれば、歩行者Ｗは、係止孔１７の周縁に引っ掛る状態で、路面側への落下が防止され、路面からのダメージを受けない。   And the airbag 14 which completed the expansion | deployment is penetrated in the front-back direction, and is provided with the some locking hole 17 which can lock body parts, such as the arm W of the pedestrian W, and is comprised. From the above, if the arm A of the pedestrian W is inserted into the locking hole 17 and locked, the pedestrian W is prevented from falling to the road surface while being caught on the periphery of the locking hole 17, No damage from the road.

したがって、実施形態の歩行者保護装置Ｓでは、一次衝突時の歩行者Ｗを保護でき、さらに、一次衝突後の歩行者Ｗの路面側への落下を防止することもできる。   Therefore, the pedestrian protection apparatus S of the embodiment can protect the pedestrian W at the time of the primary collision, and can further prevent the pedestrian W from falling to the road surface side after the primary collision.

そして、実施形態の場合、展開膨張完了時のエアバッグ１４は、前面側を、車両後方側に凹ませるような凹面１９として、形成されていることから、一次衝突時のエアバッグ１４の前面側で、歩行者Ｗが拘束されれば、凹面１９のより凹んだ側に案内され易く、係止孔１７に対して、歩行者Ｗの腕Ａ等の一部を深く侵入させる、あるいは、当初、係止孔１７に係止されていなくとも、係止孔１７に侵入させる事態を招き易く、一層、一次衝突後の歩行者Ｗの路面側への落下を防止することもできる。   And in the case of embodiment, since the airbag 14 at the time of completion of expansion | deployment is formed as the concave surface 19 which makes the front side concave to the vehicle rear side, it is the front side of the airbag 14 at the time of a primary collision. Then, if the pedestrian W is restrained, it is easy to be guided to the concave side of the concave surface 19, and a part of the arm A or the like of the pedestrian W is deeply intruded into the locking hole 17, or initially, Even if it is not locked in the locking hole 17, it is easy to cause a situation of entering the locking hole 17, and it is possible to further prevent the pedestrian W from falling to the road surface side after the primary collision.

特に、実施形態のエアバッグ１４では、膨張完了時の各縦棒部１６の下部１６ｂ側や基部１５が、前後方向の厚さを厚くして、フードパネル９の前部９ａ側で、後面側を支持される態様となって、各縦棒部１６の上端部１６ａ側が、後方側へ倒れ難く、さらに、上端部１６ａ相互が上連結部１８で連結されて、左右方向へも倒れ難く、係止孔１７の周縁で係止した歩行者Ｗを、エアバッグ１４の各部位１５・１６・１８でのクッション作用を確保した状態で、安定して、保持することが可能となる。勿論、エアバッグ１４の下部側では、基部１５が前後方向の厚さを厚くして、フロントバンパ４上で、保持されているため、展開膨張を完了させたエアバッグ１４は、前方側への倒れも、防止されている。   In particular, in the airbag 14 of the embodiment, the lower portion 16b side and the base portion 15 of each vertical bar portion 16 at the time of completion of inflation are thickened in the front-rear direction so that the front side 9a side of the hood panel 9 is rear side The upper end portion 16a side of each vertical bar portion 16 is not easily tilted backward, and the upper end portions 16a are connected to each other by the upper connecting portion 18 so that the vertical bar portion 16 is not easily tilted in the left-right direction. The pedestrian W locked at the periphery of the stop hole 17 can be stably held in a state where the cushioning action is secured at each of the parts 15, 16, and 18 of the airbag 14. Of course, on the lower side of the airbag 14, the base portion 15 is thickened in the front-rear direction and is held on the front bumper 4. Falling is also prevented.

なお、実施形態では、展開膨張させるエアバッグ１４を、フロントバンパ４の上壁部４ａ側から上方へ突出させた場合を示したが、フロントバンパ４の正面壁部４ｂやフロントグリル５の前面側から、上方へ突出させるように、エアバッグ１４を配設させてもよい。   In the embodiment, the airbag 14 to be deployed and inflated is projected upward from the upper wall 4a side of the front bumper 4. However, the front wall 4b of the front bumper 4 and the front side of the front grill 5 are shown. The air bag 14 may be disposed so as to protrude upward.

また、実施形態では、歩行者Ｗの腕Ａ等の身体部位を係止する係止孔１７として、水平方向の開口幅を狭くして上下方向に延びる隙間ｈを設けるように、形成して、左右方向に並設した場合を示したが、歩行者Ｗの身体部位を係止できれば、上下方向の開口幅を狭くして水平方向に延びる隙間を形成して、上下方向に並設する係止孔としてもよい。但し、実施形態のように、水平方向の開口幅を狭くして上下方向に延びる隙間ｈを設けて、係止孔１７を形成した場合には、係止した腕Ｗ等の身体部位を、フードパネル９の上面側に配置される基部１５まで、係止した状態で、下方移動させることが可能となることから、歩行者Ｗの転倒や自重等による移動の自由度を、ある程度確保した状態で、歩行者Ｗを係止することが可能となる。   Further, in the embodiment, the locking hole 17 for locking the body part such as the arm A of the pedestrian W is formed so as to provide a gap h extending in the vertical direction by narrowing the horizontal opening width, Although the case where it arranged in parallel in the left-right direction was shown, if the body part of the pedestrian W can be locked, the gap | interval which extends in the horizontal direction by narrowing the opening width of the up-down direction and forming in the up-down direction will be shown. It may be a hole. However, when the locking hole 17 is formed by narrowing the opening width in the horizontal direction and providing the gap h extending in the vertical direction as in the embodiment, the body part such as the locked arm W is attached to the hood. Since it is possible to move down to the base 15 arranged on the upper surface side of the panel 9 in a locked state, the degree of freedom of movement due to the pedestrian W falling down or its own weight is secured to some extent. The pedestrian W can be locked.

さらに、実施形態の場合、エアバッグ１４として、各縦棒部１６の上端部１６ａ側を、膨張可能な上連結部１８によって、連結させた場合を示したが、各縦棒部１６の上端部１６ａ相互を連結させることができれば、膨張用ガスを流入させない連結布等によって、エアバッグ１４の上端側を構成してもよい。   Further, in the case of the embodiment, the case where the upper end portion 16a side of each vertical bar portion 16 is connected by the inflatable upper connecting portion 18 as the airbag 14 is shown. As long as 16a can be connected, the upper end side of the airbag 14 may be comprised by the connection cloth etc. which do not flow in the gas for inflation.
