Embodiment Construction

[0031] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a perspective view showing an automobile including the pedestrian protection device in the embodiment. figure 2 is along figure 1 Sectional view of line II-II. image 3 is a top view of the airbag.

[0032] Such as figure 1 As shown in (a), the automobile 1 is a sedan with 4 doors, but the present invention is not limited thereto. The rear portion of the engine cover 3 or the cowl top cover 2 is provided with an airbag device for protecting pedestrians, etc. When a collision occurs with pedestrians, the airbags for protecting pedestrians (hereinafter sometimes referred to as airbags) 10 are placed on the windshield glass 5. The surrounding expansion expands and protects pedestrians and the like.

[0033] The airbag device for pedestrian protection includes the airbag 10, an inflator 21 for supplying gas to the airbag 10, a housing 22 that accommodates the...

Abstract

An airbag for protecting a pedestrian or the like and an airbag device for protecting a pedestrian or the like including the airbag are disclosed. The airbag is quickly deployed to a predetermined deployment area without the use of a high output inflator and has a high absorption property of impact which is applied to the pedestrian or the like. In one form, an airbag for protecting a pedestrian or the like comprises a lower side portion provided so as to extend along a cowl top, left and right side portions and provided so as to extend along left and right A pillars, respectively, and an upper side portion connecting top portions of the left and right side portions. A horizontally central portion of the upper side portion is connected to the left and right side portions by small flow path cross-sectional portions. When the airbag is inflated, introduction of gas to the upper side portion from the left side portion and the right side portion is restricted, so that the internal pressures of the lower side portion, the left side portion, and the right side portion become high early. Thereafter, the gas gradually flows to the upper side portion, so that the internal pressure of the entire airbag is relatively low.

Description

technical field [0001] The present invention relates to a vehicle that, when colliding with pedestrians, bicycles, motorcycles, etc., expands along the outer surface of the vehicle body to prevent passengers on pedestrians, bicycles, motorcycles, etc. (hereinafter referred to as pedestrians, etc.) An airbag for protecting a pedestrian or the like that is in direct contact with a relatively rigid part such as a pillar portion of a vehicle, and an airbag device for protecting a pedestrian or the like including the airbag for protecting a pedestrian or the like. Background technique [0002] When a car collides with pedestrians, bicycles, small motorcycles, etc. during driving, sometimes the lower body of the hit pedestrian is swept by the front of the car body and bounces onto the hood covering the front of the car body. Parts with higher rigidity, such as parts, undergo secondary collisions. [0003] In Fig. 10 of Japanese Unexamined Publication No. 2000-264146, a protective...
