  In addition, although the folding shape and folding process of the airbag 21 can take various configurations, for example, the first air chamber and the second air chamber are separately folded, and the first air chamber is After the expansion, the second air chamber is folded so as to expand. Then, the second air chamber is wound in a roll shape from the distal end portion, and the winding direction is a direction in which the distal end portion which is the upper end portion is wound around the A pillar 14 side, that is, the lower side. Is rotated so as to rub the A-pillar 14 when it is rewound during deployment. Next, the first air chamber is folded so as to wrap along the wound second air chamber by simply spreading the bag flat. In other words, the first air chamber is folded with a small expansion resistance with respect to the second air chamber, and the first air chamber is folded so as to be rapidly deployable from the second air chamber. And in the state folded in this way, shape is hold | maintained with the wrapping member etc. which are not shown in figure, and a folding process is complete | finished.

  Next, the operation of the pedestrian protection device 10 will be described.

  First, in a state in which the folded airbag 21 is stored in the case 25, when the control device detects a collision between the front portion of the vehicle body 1 and a pedestrian, that is, detects an impact of an actual collision, or advances the vehicle. When it is determined that the collision is inevitable by calculating from the speed and the distance from the pedestrian, the control device supplies a signal, that is, electric power, and activates the inflator 22. Then, this inflator 22 supplies gas to the 1st air chamber of the airbag 21 from a gas injection part. Then, as shown in FIGS. 1 (a) and 3 (a), first, the tear line 56 of the case 25 provided on the cowl top cover 8 is broken by this development pressure, so that the cowl top cover 8 is cleaved. With the hinge portion 57 as a fulcrum, the closed lid portion 55 is rotated and opened as shown by an arrow A in FIGS. Then, as shown in the broken line of FIG. 1A and FIG. 3B, the lid portion 55 comes into contact with the inclined surface 13a of the hood side receiving portion 13 of the hood 3 from the lower front side, and the rear end portion of the hood 3 Is pushed upward and moved backward. Then, the rear side portion of the hood 3 is located immediately above the opening 53 of the case 25 of the airbag 21, and the airbag 21 that is deployed from the opening 53 comes into contact with the hood 3 in a wide area so that the hood 3 is Push up. Further, as the airbag 21 is deployed, the lid 55 is moved rearward away from the hood side receiving portion 13 and covers members such as the wiper shaft 58 of the cover portion 8a of the cowl top cover 8. Then, as shown in FIGS. 1 (b) and 3 (c), the airbag 21 to be deployed pushes up the hood side receiving portion 13 of the hood 3 so as to jump up. In this state, a gap is ensured between the hood 3 and the member in the engine room 2 by the hood pushing portion 43 of the first air chamber of the airbag 21. Further, in this state, the airbag 21 is guided by the lid portion 55 that covers the member such as the wiper shaft 58 of the cover portion 8a of the cowl top cover 8, so that the airbag 21 is not interfered by the member such as the wiper shaft 58 and the like. Deploy smoothly to the side.

  Further, in the airbag 21, gas is supplied from the first air chamber to the second air chamber via the communication portions provided in the vicinity of both end portions in the both side directions in a state where the first air chamber is sufficiently deployed. The pillar covering portion 46 of the second air chamber is developed. The pillar covering portion 46 is rewound while being rotated so as to rub the A pillar 14, and as shown in FIG. 2, part or all of the A pillar 14 is covered by the pillar covering portion 46, and The cowl 7 and the lower end of the windshield 5 are covered by the cowl covering portions of the first air chamber and the second air chamber.

  In this state, when a pedestrian who is lifted up collides with the hood 3, the hood 3 is deformed with a sufficient stroke, exhibits a predetermined shock absorption characteristic, and alleviates the impact on the pedestrian. The airbag 21 and the lid 55 cover the uneven member of the cowl 7, etc., and the airbag 21 covers the uneven member of the A pillar 14 and the cowl 7, and walk with these members. It avoids collisions with people and protects pedestrians.

  Thus, according to the present embodiment, in the so-called pedestrian airbag device disposed in the cowl portion 7 of the automobile, the case 25 for housing the airbag 21 and the inflator 22 is integrated with the cowl top cover 8. Thus, modularization is possible, and the manufacturing cost can be reduced.

  By storing the airbag 21 in the cowl top cover 8, the storage position of the airbag 21 is limited, and the airbag 21 is positioned relatively rearward with respect to the hood 3.

  That is, the lid portion 55 of the case 25 containing the airbag 21 can be rotated rearward, the hood 3 can be moved rearward, and the hood side receiving portion with which the lid portion 55 to be deployed abuts. 13 is provided. Therefore, when the airbag 21 is deployed, the lid portion 55 lifts the rear side portion of the hood 3 slightly upward, and the lid portion 55 pushes the hood side receiving portion 13 to move the entire hood 3 backward. Therefore, the area where the deploying airbag 21 contacts the hood 3, that is, a large pressure receiving surface can be secured, and the airbag 21 can be surely moved upward by effectively utilizing the inflation force of the airbag 21. Can be moved.

  Further, the opened lid portion 55 moves further rearward to cover members such as the wiper shaft 58 of the cover portion 8a of the cowl top cover 8 and the main body portion of the wiper. The portion 55 prevents the occupant's head and the like from coming into contact with members such as the wiper shaft 58, thereby effectively protecting non-occupants.

  Further, since the lid portion 55 covers members such as the wiper shaft 58 of the cowl portion 7, interference between these members and the airbag 21 is suppressed, and further, the airbag 21 is guided to the airbag. 21 can be smoothly deployed in a desired state.

  In addition, the lid 55 serves as a receiving plate for receiving the airbag 21 that is deployed, and can reliably transmit the force that the airbag 21 deploys to the hood 3 at the initial stage of deployment, so that the hood 3 can be lifted quickly and reliably. it can. This effect is also effective in a configuration in which the hood 3 is not moved backward. And in the structure which does not move the hood 3 back, the cover part 55 can also fracture | rupture a rear side edge part, and can also rotate it using a front side edge part as a fulcrum.

  Further, the hood side receiving portion 13 of the hood 3 is folded back at the rear end portion of the hood 3 and is positioned slightly in front of the rear end of the hood 3, so that the hood side receiving portion 13 is rearward of the rear end or rear end of the hood 3. The hood 3 can be moved upward with more reliable contact with the lid portion 55 than the configuration provided in FIG.

  In addition, it is not restricted to said embodiment, The food | hood side receiving part 13 of the food | hood 3 can take an appropriate | suitable shape. For example, as schematically shown in FIG. 3, the rear end portion of the hood 3 is simply tilted downward and bent to form the hood side receiving portion 13, thereby simplifying the structure.

  Further, regarding the lid portion 55 of the case 25 provided on the cowl top cover 8, in addition to a portion that pivots rearwardly, the direction in which the airbag 21 is tilted from the rear side by the deployment pressure when the airbag 21 is deployed, Alternatively, a portion that rotates with the front side portion as a fulcrum can be provided to serve as a guide portion for the airbag 21.

  For example, in the configuration shown in FIG. 5, a guide portion 62 is formed near the end portion in the both-side direction W so as to rotate upward with the front end portion as a fulcrum 61 when the airbag 21 is deployed. Further, the guide portion 62 is provided with a side cover portion 63 that covers the support portion 12 that is a hinge mechanism, and a corner cover portion 64 that covers a corner portion of the rear end of the hood 3. Therefore, when the airbag 21 is deployed, the interference with the support portion 12 that is a mechanical part of the hood 3 and the influence from the sharp edge of the corner portion of the hood 3 are suppressed, and further, the airbag 21 is guided, For example, the airbag 21 can be smoothly deployed obliquely rearward of the vehicle.
