The front part 1a is provided with a hood (front hood) 3 as an exterior covering the internal accommodation space. A cowl (outer plate portion) 22 between the hood 3 and the front windshield 21 is provided with a wiper base and a ventilator air inlet. Below the hood 3 (the front surface of the vehicle 1), a bumper 23 is provided as a buffer portion for reducing and absorbing the impact of the collision. The central part 1b constitutes a guest room. The rear part 1c constitutes a trunk, for example.
　保護装置５は、車両１と衝突した被衝突体を車両に拘束し、その保護を図る車両用保護装置である。保護装置５は、格納ユニット１０を含む。図１には、格納ユニット１０の構造が模式的に図示されている。格納ユニット１０は、エアバッグ１１を格納するユニットである。本実施形態では、格納ユニット１０は、車両１のフロントウインドシールド２１の下方、具体的には、カウル２２に内蔵（格納）されている。 The protection device 5 is a vehicle protection device that constrains a collided object that collides with the vehicle 1 to the vehicle and protects it. The protection device 5 includes a storage unit 10. FIG. 1 schematically shows the structure of the storage unit 10. The storage unit 10 is a unit for storing the airbag 11. In the present embodiment, the storage unit 10 is built (stored) below the front windshield 21 of the vehicle 1, specifically, in the cowl 22.
　格納ユニット１０は、その外壁を構成する筐体１０ａ及びカバー１０ｂを有する。筐体１０ａは、前側（車両１の前方側）に開口を有し、カバー１０ｂは、筐体１０ａの開口を塞ぐように筐体１０ａに取り付けられている。カバー１０ｂは、エアバッグ１１が展開される際に、展開の付勢力によって筐体１０ａから分離されるように、或いは、破断されるように構成されている。 The storage unit 10 has a housing 10a and a cover 10b that constitute the outer wall thereof. The casing 10a has an opening on the front side (the front side of the vehicle 1), and the cover 10b is attached to the casing 10a so as to close the opening of the casing 10a. When the airbag 11 is deployed, the cover 10b is configured to be separated from the housing 10a by the urging force of deployment or to be broken.
　エアバッグ１１は、折り畳まれた状態（格納状態）で格納ユニット１０に格納されている。エアバッグ１１は、展開ユニット１２（車両１）に固定される固定端部１１ａを有する。エアバッグ１１は、例えば、展開状態において、固定端部１１ａから袋状に展開される（膨張する）。エアバッグ１１は、全体として、柔軟性や耐熱性を有する材料から構成される。 The airbag 11 is stored in the storage unit 10 in a folded state (stored state). The airbag 11 has a fixed end portion 11a fixed to the deployment unit 12 (vehicle 1). For example, the airbag 11 is deployed (inflated) in a bag shape from the fixed end portion 11a in the deployed state. The airbag 11 is made of a material having flexibility and heat resistance as a whole.
　格納ユニット１０には、展開ユニット１２が設けられている。展開ユニット１２は、エアバッグ１１を、車両１に格納された格納状態から車両１の前方へ展開させる。展開ユニット１２は、例えば、空気を射出して空気圧によって布製のエアバッグ１１を展開させるものであって、具体的には、インフレータなどのガス圧発生デバイスを含む。展開ユニット１２が作動すると、エアバッグ１１は、カバー１０ｂを飛ばしながら格納ユニット１０から射出されて膨張し、車両１の外部へ展開される。本実施形態では、図２に示すように、エアバッグ１１は、展開ユニット１２によって車両１の前方へ展開され、展開状態において車両１のフード３の全体を覆うように構成されている。なお、エアバッグ１１の射出方向は、筐体１０ａの構成や配置、展開ユニット１２の配置などによって設定することが可能である。 The expansion unit 12 is provided in the storage unit 10. The deployment unit 12 deploys the airbag 11 from the stored state stored in the vehicle 1 to the front of the vehicle 1. The deployment unit 12 is, for example, a unit that injects air and deploys the fabric airbag 11 by air pressure, and specifically includes a gas pressure generating device such as an inflator. When the deployment unit 12 is actuated, the airbag 11 is ejected from the storage unit 10 while inflating the cover 10b, and is expanded to the outside of the vehicle 1. In the present embodiment, as shown in FIG. 2, the airbag 11 is deployed forward of the vehicle 1 by the deployment unit 12 and is configured to cover the entire hood 3 of the vehicle 1 in the deployed state. The injection direction of the airbag 11 can be set by the configuration and arrangement of the casing 10a, the arrangement of the deployment unit 12, and the like.
　保護装置５は、センサ１４と、ＥＵＣ１５とを更に含む。センサ１４は、被衝突体を検知するセンサであって、例えば、車両１の周辺の物体を検知する物体検知センサや車両１に物体が接触（衝突）したことを検知する接触検知センサを含む。物体検知センサとしては、例えば、カメラやレーダーなどを含む。接触検知センサとしては、例えば、物体検知センサの他に、加速度センサ、圧力センサ、タッチセンサなどを含む。本実施形態では、センサ１４は、車両１の前部１ａ、具体的には、車両１の前面に配置されているが、これに限定されるものではない。例えば、センサ１４は、車両１の前面以外の部位に配置されてもよいし、複数配置されてもよい。 The protection device 5 further includes a sensor 14 and an EUC 15. The sensor 14 is a sensor that detects a collision target, and includes, for example, an object detection sensor that detects an object around the vehicle 1 and a contact detection sensor that detects that an object has contacted (collised) the vehicle 1. Examples of the object detection sensor include a camera and a radar. Examples of the contact detection sensor include an acceleration sensor, a pressure sensor, a touch sensor and the like in addition to the object detection sensor. In the present embodiment, the sensor 14 is disposed on the front portion 1a of the vehicle 1, specifically, the front surface of the vehicle 1, but is not limited thereto. For example, the sensor 14 may be disposed in a portion other than the front surface of the vehicle 1 or a plurality of sensors 14 may be disposed.
　ＥＣＵ１５は、センサ１４の検知結果に基づいて、展開ユニット１２を制御する制御ユニットである。ＥＣＵ１５は、例えば、ＣＰＵなどのプロセッサと、ＲＡＭやＲＯＭなどの記憶デバイスと、外部デバイスとのインタフェースとを含む。プロセッサは、記憶デバイスに記憶されたプログラムを実行する。ＥＣＵ１５は、例えば、センサ１４の検知結果から、車両１が被衝突体に衝突したと判定した場合、或いは、車両１が被衝突体に衝突する可能性が高いと判定した場合（衝突を予測した場合）に、展開ユニット１２を作動させる。なお、ＥＣＵ１５は、センサ１４の検知結果から、被衝突体が人間（例えば、歩行者）であるか否かを判定し、被衝突体が人間であると判定した場合には、展開ユニット１２を作動させ、被衝突体が人間でないと判定した場合には、展開ユニット１２を作動させないように、展開ユニット１２を制御することも可能である。 The ECU 15 is a control unit that controls the deployment unit 12 based on the detection result of the sensor 14. The ECU 15 includes, for example, a processor such as a CPU, a storage device such as a RAM and a ROM, and an interface with an external device. The processor executes a program stored in the storage device. For example, when the ECU 15 determines from the detection result of the sensor 14 that the vehicle 1 has collided with the colliding object, or when it is determined that the vehicle 1 is highly likely to collide with the colliding object (predicted collision). Case), the deployment unit 12 is actuated. The ECU 15 determines whether or not the collision target is a human (for example, a pedestrian) from the detection result of the sensor 14, and when determining that the collision target is a human, the ECU 15 When it is determined that the collision target is not a human, the deployment unit 12 can be controlled so that the deployment unit 12 is not activated.
　本実施形態では、センサ１４と展開ユニット１２との間にＥＣＵ１５を介在させている。但し、センサ１４と展開ユニット１２との間にＥＣＵ１５を介在させず、センサ１４から展開ユニット１２に電気信号（検知信号）を直接入力して展開ユニット１２を作動させる構成も採用可能である。 In this embodiment, an ECU 15 is interposed between the sensor 14 and the deployment unit 12. However, it is also possible to employ a configuration in which the deployment unit 12 is operated by directly inputting an electrical signal (detection signal) from the sensor 14 to the deployment unit 12 without interposing the ECU 15 between the sensor 14 and the deployment unit 12.
　図３及び図４を参照して、保護装置５の動作例について説明する。図３は、車両１と被衝突体１００とが衝突した状態を示している。被衝突体１００は、ここでは、人間とする。図３に示すように、センサ１４が車両１に被衝突体１００が衝突したことを検知すると、ＥＣＵ１５は、展開ユニット１２を作動させる。これにより、図４に示すように、エアバッグ１１が、瞬時に、カウル２２からバンパー２３の前方にわたって（即ち、フード３の全体及びバンパー２３の前面全体を覆うように）展開される。 An example of the operation of the protective device 5 will be described with reference to FIGS. FIG. 3 shows a state where the vehicle 1 and the collision target 100 collide. Here, the collision object 100 is assumed to be a human. As shown in FIG. 3, when the sensor 14 detects that the collision object 100 has collided with the vehicle 1, the ECU 15 operates the deployment unit 12. As a result, as shown in FIG. 4, the airbag 11 is instantly deployed from the cowl 22 to the front of the bumper 23 (that is, so as to cover the entire hood 3 and the entire front surface of the bumper 23).
　図５Ａは、展開状態におけるエアバッグ１１を示す図である。エアバッグ１１には、図５Ａ及び図５Ｂに示すように、被衝突体を捕捉するように互いに結合される結合部材３１が設けられている。結合部材３１は、展開状態におけるエアバッグ１１の被衝突体１００の車両１の車幅方向の両側前側表面に少なくとも配置されている。結合部材３１は、例えば、図５Ａに示すように、展開状態におけるエアバッグ１１の車両１の車幅方向の一端部から他端部にわたって連続的に延設されている。 FIG. 5A is a view showing the airbag 11 in a deployed state. As shown in FIGS. 5A and 5B, the airbag 11 is provided with a coupling member 31 that is coupled to each other so as to capture the collision target. The coupling member 31 is disposed at least on the front surfaces on both sides in the vehicle width direction of the vehicle 1 of the collision target 100 of the airbag 11 in the deployed state. For example, as illustrated in FIG. 5A, the coupling member 31 is continuously extended from one end portion in the vehicle width direction of the vehicle 1 to the other end portion of the airbag 11 in the deployed state.
　展開状態におけるエアバッグ１１に対して被衝突体１００が前方から衝突することによって、エアバッグ１１は、図５Ｂに示すように、被衝突体１００を包み込むように変形し、エアバッグ１１の少なくとも両端部前側表面に設けられた結合部材３１が互いに結合する。これにより、被衝突体１００は、バンパー２３の前方及びフード３の上でエアバッグ１１に包み込まれた状態（即ち、エアバッグ１１で捕捉された状態）となり、被衝突体１００が路面に落下し損傷することを抑制することができる。図５Ｂは、結合部材３１が互いに結合した状態におけるエアバッグ１１を示す図である。 When the collision object 100 collides with the airbag 11 in the deployed state from the front, the airbag 11 is deformed so as to wrap the collision object 100 as shown in FIG. 5B, and at least both ends of the airbag 11. The coupling members 31 provided on the front side surfaces are coupled to each other. As a result, the impacted body 100 is in a state of being wrapped in the airbag 11 in front of the bumper 23 and on the hood 3 (that is, captured by the airbag 11), and the impacted object 100 falls to the road surface. Damage can be suppressed. FIG. 5B is a diagram illustrating the airbag 11 in a state where the coupling members 31 are coupled to each other.
　以上の通り、本実施形態では、図６Ａ及び図６Ｂに示すように、被衝突体１００を車両１に拘束することができる。図６Ａは、展開状態におけるエアバッグ１１の側面図であり、図６Ｂは、結合部材３１が互いに結合した状態におけるエアバッグ１１の斜視図である。衝突時における被衝突体１００の位置や姿勢は様々であるが、結合部材３１が設けられたエアバッグ１１を用いることで、エアバッグ１１で被衝突体１００を包み込んで捕捉することができる。また、被衝突体１００の姿勢に合わせてエアバッグ１１が変形するため、被衝突体１００の多様な姿勢に対応可能である。 As described above, in this embodiment, as shown in FIGS. 6A and 6B, the collision object 100 can be restrained to the vehicle 1. 6A is a side view of the airbag 11 in a deployed state, and FIG. 6B is a perspective view of the airbag 11 in a state in which the coupling members 31 are coupled to each other. Although the position and posture of the collision object 100 at the time of the collision are various, by using the airbag 11 provided with the coupling member 31, the collision object 100 can be wrapped and captured by the airbag 11. In addition, since the airbag 11 is deformed in accordance with the posture of the collision target 100, it is possible to cope with various postures of the collision target 100.
　ここで、結合部材３１は、柔軟性を有する部材であって、例えば、面ファスナーやテープ状の磁石で構成されている。結合部材３１の車幅方向の任意の位置で被衝突体１００を捕捉できる。結合部材３１が面ファスナーである場合には、エアバッグ１１が被衝突体１００を包み込んだ状態、即ち、結合部材３１が互いに結合した状態（図５Ｂ）において、被衝突体１００の衣服にも結合部材３１が結合され、エアバッグ１１による被衝突体１００の拘束力を向上させることができる。また、結合部材３１は、複数の帯状面ファスナー３１ａで構成されていてもよい。例えば、複数の帯状面ファスナー３１は、図７に示すように、展開状態におけるエアバッグ１１の車幅方向に延設され、車両１の上下方向に離間して配置される。これにより、車両１と被衝突体１００とが衝突した場合に、被衝突体１００をエアバッグ１１で確実に捕捉することが可能となる。 Here, the coupling member 31 is a flexible member, and is composed of, for example, a hook-and-loop fastener or a tape-shaped magnet. The collision object 100 can be captured at an arbitrary position of the coupling member 31 in the vehicle width direction. When the coupling member 31 is a hook-and-loop fastener, the airbag 11 is also coupled to the clothing of the collision target 100 in a state where the airbag 11 wraps around the collision target 100, that is, in a state where the coupling members 31 are coupled to each other (FIG. 5B). The member 31 is combined and the restraining force of the collision target 100 by the airbag 11 can be improved. Moreover, the coupling member 31 may be comprised by the some strip | belt-shaped surface fastener 31a. For example, as shown in FIG. 7, the plurality of belt-shaped surface fasteners 31 extend in the vehicle width direction of the airbag 11 in the deployed state and are spaced apart in the vertical direction of the vehicle 1. Thereby, when the vehicle 1 and the collision object 100 collide, the collision object 100 can be reliably captured by the airbag 11.
　また、エアバッグ１１の内面にも、互いに結合される結合部材を設けるとよい。具体的には、図８Ａ及び図８Ｂに示すように、展開状態におけるエアバッグ１１の前側内面に結合部材４１ａを配置し、展開状態におけるエアバッグ１１の後側内面に結合部材４１ｂを配置する。結合部材４１ａ及び４１ｂは、結合部材３１と同様に、柔軟性を有する部材であって、例えば、面ファスナーやテープ状の磁石で構成されている。図８Ａは、展開状態におけるエアバッグ１１を示す図であり、図８Ｂは、結合部材３１が互いに結合した状態におけるエアバッグ１１を示す図である。上述したように、展開状態におけるエアバッグ１１に対して被衝突体１００が前方から衝突することによって、エアバッグ１１は、図８Ｂに示すように、被衝突体１００を包み込むように変形し、エアバッグ１１の両端部前側表面に設けられた結合部材３１が互いに結合する。この際、エアバッグ１１の前側内面に設けられた結合部材４１ａ及びエアバッグ１１の後側内面に設けられた結合部材４１ｂについても同様に、互いに結合する。このように、エアバッグ１１の内部でも結合部材４１ａ及び４１ｂを互いに結合させることで、車両１の挙動によるエアバッグ１１の移動量を抑制することが可能となるため、エアバッグ１１による被衝突体１００の拘束力を向上させることができる。 Further, it is preferable to provide a coupling member coupled to each other on the inner surface of the airbag 11 as well. Specifically, as shown in FIGS. 8A and 8B, the coupling member 41a is disposed on the front inner surface of the airbag 11 in the deployed state, and the coupling member 41b is disposed on the rear inner surface of the airbag 11 in the deployed state. The coupling members 41a and 41b are members having flexibility similarly to the coupling member 31, and are constituted by, for example, a hook-and-loop fastener or a tape-shaped magnet. FIG. 8A is a diagram illustrating the airbag 11 in the deployed state, and FIG. 8B is a diagram illustrating the airbag 11 in a state where the coupling members 31 are coupled to each other. As described above, the collision object 100 collides with the airbag 11 in the deployed state from the front, so that the airbag 11 is deformed so as to wrap the collision object 100 as shown in FIG. The coupling members 31 provided on the front surfaces of both ends of the bag 11 are coupled to each other. At this time, the coupling member 41a provided on the front inner surface of the airbag 11 and the coupling member 41b provided on the rear inner surface of the airbag 11 are similarly coupled to each other. As described above, since the coupling members 41 a and 41 b are coupled to each other even inside the airbag 11, the amount of movement of the airbag 11 due to the behavior of the vehicle 1 can be suppressed. 100 restraining force can be improved.
　また、車両１の前方へ展開されたエアバッグ１１を車両１（フード３）に固定する機構を設けるとよい。具体的には、図９Ａ及び図９Ｂに示すように、展開状態におけるエアバッグ１１の車両１のフード３に隣接する部位に、磁石５１を配置する。図９Ａは、展開状態におけるエアバッグ１１を示す図であり、図９Ｂは、結合部材３１が互いに結合した状態におけるエアバッグ１１を示す図である。磁石５１は、例えば、展開状態におけるエアバッグ１１の車幅方向の両端部後側表面に少なくとも配置されている。但し、磁石５１は、エアバッグ１１の後側内面、詳細には、エアバッグ１１の内側内面と結合部材４１ｂとの間に配置してもよい。車両１のフード３は、一般的には、鉄製であるため、磁石５１がフード３に引き付けられることによって、エアバッグ１１を車両１に固定することができる。なお、車両１のフード３が樹脂製である場合には、磁石５１が引き付けられる部材を、車両１に付加的に設ければよい。このように、車両１の前方へ展開されたエアバッグ１１を車両１のフード３に固定することで、車両１の挙動によるエアバッグ１１の移動量を抑制することが可能となるため、エアバッグ１１による被衝突体１００の拘束力を向上させることができる。 Also, a mechanism for fixing the airbag 11 deployed forward of the vehicle 1 to the vehicle 1 (hood 3) may be provided. Specifically, as shown in FIGS. 9A and 9B, a magnet 51 is disposed in a portion of the airbag 11 adjacent to the hood 3 of the vehicle 1 in the deployed state. FIG. 9A is a diagram showing the airbag 11 in the deployed state, and FIG. 9B is a diagram showing the airbag 11 in a state where the coupling members 31 are coupled to each other. For example, the magnet 51 is disposed at least on the rear surface of both ends in the vehicle width direction of the airbag 11 in the deployed state. However, the magnet 51 may be disposed between the rear inner surface of the airbag 11, more specifically, between the inner inner surface of the airbag 11 and the coupling member 41b. Since the hood 3 of the vehicle 1 is generally made of iron, the airbag 11 can be fixed to the vehicle 1 by attracting the magnet 51 to the hood 3. If the hood 3 of the vehicle 1 is made of resin, a member to which the magnet 51 is attracted may be additionally provided in the vehicle 1. As described above, since the airbag 11 deployed in front of the vehicle 1 is fixed to the hood 3 of the vehicle 1, the amount of movement of the airbag 11 due to the behavior of the vehicle 1 can be suppressed. 11 can improve the restraining force of the collision target 100.
　また、図１０Ａ及び図１０Ｂに示すように、エアバッグ１１には、エアバッグ１１の内圧を調整するベントホール６１が設けられている。図１０Ａは、展開状態におけるエアバッグ１１を示す図であり、図１０Ｂは、結合部材３１が互いに結合した状態におけるエアバッグ１１を示す図である。ベントホール６１は、図１０Ａに示す状態では、塞がれており、エアバッグ１１の内部の圧力は一定以上に維持されている。これは、エアバッグ１１の内部の圧力を一定以上に維持しないと、被衝突体１００の衝突時のエアバッグ１１の変形量が不足し（即ち、エアバッグ１１が被衝突体１００に回り込まず）、エアバッグ１１の両端部前側表面に設けられた結合部材３１が互いに結合することができなくなるからである。一方、図１０Ｂに示す状態では、ベントホール６１は解放される。これにより、被衝突体１００に対するエアバッグ１１の回り込み性能を調整することが可能となる。また、被衝突体１００の衝突後にエアバッグ１１の内部の圧力を低下させ、被衝突体１００の呼吸スペースを確保することが可能となる。 10A and 10B, the airbag 11 is provided with a vent hole 61 for adjusting the internal pressure of the airbag 11. FIG. 10A is a diagram illustrating the airbag 11 in the deployed state, and FIG. 10B is a diagram illustrating the airbag 11 in a state where the coupling members 31 are coupled to each other. The vent hole 61 is closed in the state shown in FIG. 10A, and the pressure inside the airbag 11 is maintained at a certain level or higher. This is because if the pressure inside the airbag 11 is not maintained above a certain level, the deformation amount of the airbag 11 at the time of the collision of the collision target 100 is insufficient (that is, the airbag 11 does not enter the collision target 100). This is because the coupling members 31 provided on the front surfaces of the both end portions of the airbag 11 cannot be coupled to each other. On the other hand, in the state shown in FIG. 10B, the vent hole 61 is released. As a result, the wraparound performance of the airbag 11 with respect to the collision object 100 can be adjusted. In addition, it is possible to reduce the pressure inside the airbag 11 after the collision of the collision target 100 and secure a breathing space for the collision target 100.
　＜第２実施形態＞
　図１１は、本発明の第２実施形態における車両１の構成を示す概略図である。本実施形態では、車両１には、保護装置５に加えて、保護装置７０が備えられている。保護装置７０は、車両１と衝突した被衝突体を車両に拘束し、その保護を図る車両用保護装置である。保護装置７０は、保護装置５と同様に、格納ユニット７１を含む。格納ユニット７１は、エアバッグ７２を格納するユニットである。本実施形態では、格納ユニット７１は、車両１のフード３の前方の下方に格納されている。 Second Embodiment
FIG. 11 is a schematic diagram showing the configuration of the vehicle 1 in the second embodiment of the present invention. In the present embodiment, the vehicle 1 includes a protection device 70 in addition to the protection device 5. The protection device 70 is a vehicle protection device that restrains a collision object that collides with the vehicle 1 with the vehicle and protects it. The protection device 70 includes a storage unit 71 as with the protection device 5. The storage unit 71 is a unit for storing the airbag 72. In the present embodiment, the storage unit 71 is stored in the lower front of the hood 3 of the vehicle 1.
　エアバッグ７２は、エアバッグ１１と同様に、折り畳まれた状態（格納状態）で格納ユニット７１に格納されている。エアバッグ７２は、車両１に固定される固定端部を有する。図１２Ａに示すように、エアバッグ７２は、例えば、展開状態において、固定端部から袋状に展開される（膨張する）。 The airbag 72 is stored in the storage unit 71 in a folded state (stored state), like the airbag 11. The airbag 72 has a fixed end portion that is fixed to the vehicle 1. As shown in FIG. 12A, for example, the airbag 72 is deployed (inflated) in a bag shape from the fixed end in the deployed state.
　格納ユニット７１には、展開ユニット７３が設けられている。展開ユニット７３は、図１２Ａに示すように、エアバッグ７２を、車両１に格納された格納状態から車両１の前方へ展開させる。本実施形態では、エアバッグ７２は、展開ユニット７３によって車両１のバンパー２３の前方で展開される。従って、エアバッグ１１は、エアバッグ７２よりも相対的に車両１の上側で展開され、エアバッグ７２は、エアバッグ１１よりも相対的に車両１の下側で展開される。 The storage unit 71 is provided with a deployment unit 73. As shown in FIG. 12A, the deployment unit 73 deploys the airbag 72 from the stored state stored in the vehicle 1 to the front of the vehicle 1. In the present embodiment, the airbag 72 is deployed in front of the bumper 23 of the vehicle 1 by the deployment unit 73. Therefore, the airbag 11 is deployed on the upper side of the vehicle 1 relative to the airbag 72, and the airbag 72 is deployed on the lower side of the vehicle 1 relative to the airbag 11.
　ＥＣＵ１５は、本実施形態では、センサ１４の検知結果に基づいて、展開ユニット１２及び７３を制御する。ＥＣＵ１５は、例えば、センサ１４の検知結果から、車両１が被衝突体に衝突したと判定した場合、或いは、車両１が被衝突体に衝突する可能性が高いと判定した場合に、展開ユニット１２及び７３を作動させる。 In this embodiment, the ECU 15 controls the deployment units 12 and 73 based on the detection result of the sensor 14. For example, when the ECU 15 determines from the detection result of the sensor 14 that the vehicle 1 has collided with the collision target, or when it is determined that the vehicle 1 is highly likely to collide with the collision target, the deployment unit 12 And 73 are activated.
　図１２Ａ及び図１２Ｂを参照して、保護装置５及び７０の動作例について説明する。図１２Ａに示すように、センサ１４が車両１に被衝突体１００が衝突したことを検知すると、ＥＣＵ１５は、展開ユニット１２及び７３を作動させる。これにより、図１２Ａに示すように、エアバッグ１１が車両１のフード３の上で展開され、エアバッグ７２が車両１のバンパー２３の前方で展開される。 An example of the operation of the protection devices 5 and 70 will be described with reference to FIGS. 12A and 12B. As shown in FIG. 12A, when the sensor 14 detects that the collision object 100 has collided with the vehicle 1, the ECU 15 operates the deployment units 12 and 73. Thereby, as shown in FIG. 12A, the airbag 11 is deployed on the hood 3 of the vehicle 1, and the airbag 72 is deployed in front of the bumper 23 of the vehicle 1.

As shown in FIG. 12B, the airbag 72 is provided with a coupling member 74 that couples to each other in the same manner as the airbag 11. The coupling member 74 is disposed at least on the front surfaces of both ends of the airbag 72 in the vehicle width direction of the vehicle 1 in the deployed state. The coupling member 74 extends continuously from one end portion to the other end portion in the vehicle width direction of the vehicle 1 of the airbag 11 in the deployed state. In this embodiment, the coupling member 74 is composed of a plurality of strip-shaped surface fasteners that are spaced apart in the vertical direction of the vehicle 1.
　このように、本実施形態では、エアバッグ１１をカウル２２及びフード３の全体に展開させることで、例えば、エアバッグ１１で被衝突体１００の頭部から腰までを包み込み、エアバッグ７２をバンパー２３の前方で展開させることで、例えば、エアバッグ７２で被衝突体１００の脚部を包み込むことができる。これにより、車両１と被衝突体１００とが衝突した場合に、被衝突体１００をエアバッグ１１及び７２で確実に捕捉することが可能となる。また、被衝突体が子供である場合には、被衝突体１００をエアバッグ７２で確実に捕捉することが可能となる。なお、第１実施形態で説明したように、エアバッグ７２の内面にも互いに結合される結合部材を設けてもよいし、車両１の前方へ展開されたエアバッグ７２を車両１（バンパー２３）に固定する機構を設けてもよいし、エアバッグ７２の内圧を調整するベントホールを設けてもよい。 Thus, in this embodiment, by deploying the airbag 11 over the cowl 22 and the hood 3, for example, the airbag 11 wraps from the head to the waist of the collision target 100, and the airbag 72 is made to be a bumper. For example, the leg portion of the collision target 100 can be wrapped with the airbag 72. Thereby, when the vehicle 1 and the collision object 100 collide, the collision object 100 can be reliably captured by the airbags 11 and 72. Further, when the collision object is a child, the collision object 100 can be reliably captured by the airbag 72. As described in the first embodiment, a coupling member coupled to each other may be provided on the inner surface of the airbag 72, or the airbag 72 deployed forward of the vehicle 1 may be provided in the vehicle 1 (bumper 23). A mechanism for fixing the air bag 72 may be provided, or a vent hole for adjusting the internal pressure of the airbag 72 may be provided.
　また、車両１は、保護装置５を備えず、保護装置７０のみを備えていてもよい。このような場合には、図１３に示すように、エアバッグ７２が、バンパー２３の前方に加えて、フロントウインドシールド２１の前方にも展開されるようにすればよい。 Further, the vehicle 1 may include only the protection device 70 without including the protection device 5. In such a case, as shown in FIG. 13, the airbag 72 may be deployed not only in front of the bumper 23 but also in front of the front windshield 21.
　以上、本発明の好ましい実施形態について説明したが、本発明はこれらの実施形態に限定されないことはいうまでもなく、その要旨の範囲内で種々の変形及び変更が可能である。 As mentioned above, although preferable embodiment of this invention was described, it cannot be overemphasized that this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
