A center console 16 is provided between the left and right footrests 5 to incorporate an engine unit (not shown), and a rear wheel 8 is pivotally supported at the rear end of a power transmission unit 17 extending rearward from the engine unit. Yes.

図２にも示すように、この自動二輪車１には上下２つのエアバッグ装置が備えられている。運転者の上半身に対応する上部エアバッグ装置２１と下半身に対応する下部エアバッグ装置２２である。図２では上下のエアバッグ装置２１，２２のエアバッグが展開した状態が線２１ａ，２２ａで示されている。線Ｒは運転者の輪郭である。   As shown in FIG. 2, the motorcycle 1 is provided with two upper and lower airbag devices. An upper airbag device 21 corresponding to the upper body of the driver and a lower airbag device 22 corresponding to the lower body. In FIG. 2, the state where the airbags of the upper and lower airbag devices 21 and 22 are deployed is indicated by lines 21a and 22a. Line R is the contour of the driver.

上部エアバッグ装置２１は、例えばハンドルバー３の略中央部に設置されたエアバッグ取付ブラケット２５に設置されている。図３〜図５に示すように、エアバッグ取付ブラケット２５は箱状のエアバッグ収納部２６の底面に左右一対の支持ステー２７，２７が固定された構造である。図４と図５に示すエアバッグ取付ブラケット２５にはエアバッグ収納部２６の前後上縁に平板状のエアバッグ受け２８，２９が設けられている。   The upper airbag device 21 is installed, for example, on an airbag mounting bracket 25 installed at a substantially central portion of the handle bar 3. As shown in FIGS. 3 to 5, the airbag mounting bracket 25 has a structure in which a pair of left and right support stays 27 are fixed to the bottom surface of a box-shaped airbag storage portion 26. The airbag mounting bracket 25 shown in FIGS. 4 and 5 is provided with flat airbag receivers 28 and 29 at the front and rear upper edges of the airbag storage portion 26.

エアバッグ取付ブラケット２５の支持ステー２７，２７はハンドルバー３をクランプ固定するハンドルホルダー３１とともにフロントフォーク３２の上部に固定されており、エアバッグ収納部２６にインフレーター３３と折りたたまれたエアバッグ２１ａが収納され、カバー３４で閉塞される。   The support stays 27 of the airbag mounting bracket 25 are fixed to the upper portion of the front fork 32 together with the handle holder 31 for clamping the handlebar 3, and the airbag 21 a folded with the inflator 33 is installed in the airbag storage portion 26. It is stored and closed with a cover 34.

図５に示すように、上部エアバッグ装置２１のエアバッグ２１ａは、その展開状態において運転者がハンドルバー３を把持可能な形状に形成されている。即ち、展開状態にあるエアバッグ２１ａの横幅Ｗ１が、ハンドルバー３の左右グリップ間の内寸Ｗ２よりも小さくされている。   As shown in FIG. 5, the airbag 21 a of the upper airbag device 21 is formed in a shape that allows the driver to grip the handlebar 3 in the deployed state. That is, the lateral width W1 of the airbag 21a in the deployed state is made smaller than the inner dimension W2 between the left and right grips of the handle bar 3.

また、インフレーター３３の中心Ｏから、展開状態にあるエアバッグ２１ａの上端までの寸法Ｌ１が、中心Ｏからエアバッグ２１ａ下端までの寸法Ｌ２よりも小さくされている。寸法Ｌ１と寸法Ｌ２は、図２に示すようにエアバッグ２１ａの展開時にエアバッグ２１ａ上端の高さが着座シート４に座った運転者の目線以下になり、エアバッグ２１ａ下端が運転者の膝の上に押し付けられる程度に設定されている。   Further, the dimension L1 from the center O of the inflator 33 to the upper end of the airbag 21a in the deployed state is smaller than the dimension L2 from the center O to the lower end of the airbag 21a. As shown in FIG. 2, the dimension L1 and the dimension L2 are such that when the airbag 21a is deployed, the height of the upper end of the airbag 21a is equal to or less than the line of sight of the driver sitting on the seating seat 4, and the lower end of the airbag 21a is It is set so that it can be pressed on the top.

一方、下部エアバッグ装置２２はレッグシールド１４の後面に設置されている。レッグシールド１４の後面にはエアバッグ収納部３７が設けられており、その内部にインフレーター３８と折りたたまれたエアバッグ２２ａが収納され、カバー３９で閉塞される。   On the other hand, the lower airbag device 22 is installed on the rear surface of the leg shield 14. An airbag storage portion 37 is provided on the rear surface of the leg shield 14, and the inflator 38 and the folded airbag 22 a are stored therein and closed with a cover 39.

下部エアバッグ装置２２のエアバッグ２２ａは、その展開時にエアバッグ収納部３７から後方および左右に拡張し、エアバッグ２２ａの後面が着座シート４に座った運転者の左右の脛に前方から当接するように造形されている。   The airbag 22a of the lower airbag device 22 expands rearward and leftward and rightward from the airbag storage portion 37 when deployed, and the rear surface of the airbag 22a comes into contact with the left and right shins of the driver sitting on the seat 4 from the front. It is shaped like this.

自動二輪車１の車体には図示しない加速度センサー等の衝撃感知手段が設けられており、この衝撃感知手段が自動二輪車１の衝突時等に所定値以上の衝撃を感知すると上部エアバッグ装置２１および下部エアバッグ装置２２のインフレーター３３，３８を発動させ、インフレーター３３，３８が上下のエアバッグ２１ａ，２２ａに高圧ガスを急速充填してエアバッグ２１ａ，２２ａを展開させる。   The vehicle body of the motorcycle 1 is provided with impact sensing means such as an acceleration sensor (not shown). When the impact sensing means senses an impact of a predetermined value or more when the motorcycle 1 collides, the upper airbag device 21 and the lower airbag device 21 are provided. The inflators 33 and 38 of the airbag device 22 are activated, and the inflators 33 and 38 rapidly fill the upper and lower airbags 21a and 22a with high-pressure gas to deploy the airbags 21a and 22a.

上側のエアバッグ２１ａは運転者の上半身とハンドルバー３との間に展開し、運転者の上半身を衝突衝撃から保護する。運転者の上半身の衝突荷重はエアバッグを介してエアバッグ取付ブラケット２５のエアバッグ受け２８，２９に受け止められる。   The upper airbag 21a is deployed between the driver's upper body and the handlebar 3 to protect the driver's upper body from collision impact. The collision load on the upper body of the driver is received by the airbag receivers 28 and 29 of the airbag mounting bracket 25 through the airbag.

下側のエアバッグ２２ａは運転者の下半身とレッグシールド１４との間に展開し、運転者の下半身を衝突衝撃から保護する。運転者の下半身の衝突荷重はエアバッグ２２ａを介してレッグシールド１４に受け止められる。   The lower airbag 22a is deployed between the driver's lower body and the leg shield 14 to protect the driver's lower body from collision impact. The collision load on the lower body of the driver is received by the leg shield 14 via the airbag 22a.

ここで、上部エアバッグ装置２１と下部エアバッグ装置２２では、それぞれのエアバッグ展開開始タイミングとエアバッグ展開速度が異なっている。具体的には、上部エアバッグ装置２１のエアバッグ展開開始タイミングよりも、下部エアバッグ装置２２のエアバッグ展開開始タイミングをわずかに遅らせるとともに、下部エアバッグ装置２２のエアバッグ展開速度を上部エアバッグ装置のエアバッグ展開速度よりもよりも速めている。   Here, the upper airbag device 21 and the lower airbag device 22 have different airbag deployment start timings and airbag deployment speeds. Specifically, the airbag deployment start timing of the lower airbag device 22 is slightly delayed from the airbag deployment start timing of the upper airbag device 21, and the airbag deployment speed of the lower airbag device 22 is set to the upper airbag. It is faster than the airbag deployment speed of the device.

エアバッグ２１ａ、２２ａの展開速度はインフレーター３３，３８に使用する火薬の量で調節可能である。また、下部エアバッグ装置２２（エアバッグ２２ａ）の内部圧力保持時間が、上部エアバッグ装置２１（エアバッグ２１ａ）の内部圧力保持時間よりも長く設定されている。エアバッグ２１ａ，２２ａの内部圧力保持時間は、インフレーター３３，３８で発生した膨張ガスを外部に逃がすベントホール（不図示）の口径で調節することができる。   The deployment speed of the airbags 21a and 22a can be adjusted by the amount of explosive used for the inflators 33 and 38. Further, the internal pressure holding time of the lower airbag device 22 (airbag 22a) is set longer than the internal pressure holding time of the upper airbag device 21 (airbag 21a). The internal pressure holding time of the airbags 21a and 22a can be adjusted by the diameter of a vent hole (not shown) that allows the inflation gas generated by the inflators 33 and 38 to escape to the outside.

以上のように、本発明では、ハンドルバー３と着座シート４との間に低床状の足載せ部５が設けられたスクーター型の自動二輪車１において、運転者の上半身に対応する上部エアバッグ装置２１と下半身に対応する下部エアバッグ装置２２とを備えたことを特徴とする。   As described above, in the present invention, in the scooter type motorcycle 1 in which the low floor-like footrest portion 5 is provided between the handlebar 3 and the seating seat 4, the upper airbag corresponding to the upper body of the driver. An apparatus 21 and a lower airbag apparatus 22 corresponding to the lower body are provided.

これにより、上下それぞれのエアバッグ２１ａ，２２ａの展開時の容積を小さくすることができ、エアバッグ２１ａ，２２ａが完全な展開形状に展開するまでの時間を短縮して最適なタイミングでエアバッグ２１ａ，２２ａを展開制御させることができる。   Thereby, the volume at the time of deployment of the upper and lower airbags 21a and 22a can be reduced, and the time required for the airbags 21a and 22a to be deployed into a completely deployed shape is shortened, and the airbag 21a is optimally timed. , 22a can be controlled.

また、上下のエアバッグ２１ａ，２２ａの展開開始タイミングとエアバッグ展開速度を異ならせたため、上側のエアバッグ２１ａと下側のエアバッグ２２ａをそれぞれ一段と良いタイミングで展開させることができ、万一の場合に運転者を効果的に保護することができる。   In addition, since the deployment start timing and the airbag deployment speed of the upper and lower airbags 21a and 22a are made different, the upper airbag 21a and the lower airbag 22a can be deployed at a better timing respectively. In this case, the driver can be effectively protected.

特に、上側のエアバッグ２１ａの展開開始タイミングよりも下側のエアバッグ２２ａの展開開始タイミングを遅らせたことにより、下側のエアバッグ２２ａの展開中に運転者の下肢がエアバッグ２２ａに当たるため、エアバッグ２２ａを膨らませる高圧ガスの圧力により運転者の下肢を大きな力で支えることができ、小さな容量のエアバッグ２２ａでも運転者をより効果的に保護することができる。   In particular, by delaying the deployment start timing of the lower airbag 22a relative to the deployment start timing of the upper airbag 21a, the lower limbs of the driver hit the airbag 22a during deployment of the lower airbag 22a. The lower leg of the driver can be supported with a large force by the pressure of the high-pressure gas that inflates the airbag 22a, and the driver can be more effectively protected even with the airbag 22a having a small capacity.

さらに、下部エアバッグ装置２２のエアバッグ内部圧力保持時間を上部エアバッグ装置２１のエアバッグ内部圧力保持時間よりも長く設定したことにより、衝突時の挙動が異なる運転者の上半身と下半身に対応する上部エアバッグ装置２１と下部エアバッグ装置２２が、万一の場合に運転者の上半身と下半身をより効果的に支えることができ、小さな容量の下部エアバッグ装置２２でも運転者をより効果的に保護することができる。   Furthermore, by setting the airbag internal pressure holding time of the lower airbag device 22 to be longer than the airbag internal pressure holding time of the upper airbag device 21, it corresponds to the upper body and lower body of the driver whose behavior at the time of collision is different. The upper airbag device 21 and the lower airbag device 22 can support the upper and lower bodies of the driver more effectively in the event of an emergency, and the driver can be more effectively supported by the lower airbag device 22 having a small capacity. Can be protected.

また、上部エアバッグ装置２１をハンドルバー３の略中央部に設置し、下部エアバッグ装置２２をレッグシールド１４に設置したため、上部エアバッグ装置２１および下部エアバッグ装置２２がそれぞれ衝突時に運転者の体重の最も掛かる場所に配置され、これにより運転者の身体を上下のエアバッグ２１ａ，２２ａで的確に支えて運転者を一層効果的に保護することができる。   In addition, since the upper airbag device 21 is installed at a substantially central portion of the handlebar 3 and the lower airbag device 22 is installed on the leg shield 14, the upper airbag device 21 and the lower airbag device 22 are It is arranged at the place where the body weight is most applied, and thus the driver's body can be accurately supported by the upper and lower airbags 21a, 22a to protect the driver more effectively.

上部エアバッグ装置２１のエアバッグ２１ａは、その展開状態で運転者がハンドルバー３を把持可能であるため、エアバッグ２１ａが展開しても運転者がハンドルバー３を把持し続けることができ、運転者が体勢を整えることができる。   The airbag 21a of the upper airbag device 21 is capable of gripping the handlebar 3 by the driver in its deployed state, so that the driver can continue to grip the handlebar 3 even when the airbag 21a is deployed, The driver can get ready.

さらに、展開時の上側のエアバッグ２１ａ下端が着座シート４に座った運転者の膝の上に押し付けられる形状であることと、展開時の下側のエアバッグ２２ａ後面が運転者の脛に前方から当接することから、事故等の際に２つのエアバッグ２１ａ，２２ａにより運転者の下半身を着座シート４に拘束して運転者が着座シート４から浮き上がることを防止し、この点でも運転者を効果的に保護することができる。   Furthermore, the lower end of the upper airbag 21a during deployment is shaped to be pressed onto the knee of the driver sitting on the seat 4 and the rear surface of the lower airbag 22a during deployment is forward of the driver's shin. Therefore, the driver's lower body is restrained from the seating seat 4 by the two airbags 21a and 22a in the event of an accident or the like, and the driver is prevented from lifting from the seating seat 4. It can be effectively protected.
