Embodiment Construction

[0046] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a perspective view of an automobile provided with a protection device for pedestrians and the like in the embodiment. figure 2 (a) along figure 1 The sectional view of the II-II line, figure 2 (b) is a plan view of the airbag. image 3 is a time-dependent change diagram of the internal pressure of the airbag.

[0047] Such as figure 1 As shown in (a), although the automobile 1 is a sedan, the present invention is not limited to a particular form of vehicle. On the rear portion of the hood 3 or on the cowl top 2 is provided an airbag device that is deployed to inflate the airbag 10 when it collides with a pedestrian or the like.

[0048] This airbag device comprises: airbag 10, is made of the 1st airbag 11 and the 2nd airbag 12 that internal configuration this 1st airbag 11; The opening 13 that is arranged on this 1st airbag 11; An inflator 14 for supplying...

Abstract

An airbag is provided that is promptly developed in an area for the airbag to be developed without using a device provided with high output power to serve as an inflator. A protection apparatus for a pedestrian or the like having the airbag is also described. When a contact of a pedestrian with a motor vehicle is detected or predicted, the inflator 14 is activated and the airbag 10 is developed. The gas from the inflator 14 is supplied into a first bag 11 first, and the first bag 11 is thereby expanded at a high internal pressure and is developed along a cowl top 2 and an A pillar 6. Thereafter, the gas flows into the second bag 12 from the first bag 11 passing through an opening 13 that allows an inner part of the first bag 11 to communicate with that of the second bag 12, and develops the second bag 12. Since the first bag 11 is expanded and developed first, the first bag 11 can be sufficiently and promptly developed in an area for the first bag 11 to be developed without using a device provided with high output power to serve as the inflator 14.

Description

technical field [0001] The present invention relates to a method for preventing pedestrians, bicycles, small motorcycles and other occupants (hereinafter referred to as occupants) from colliding with pedestrians, bicycles, small motorcycles, etc. The higher parts are in contact, thus protecting the protective devices for pedestrians etc. and the airbags adopted. Background technique [0002] When a bicycle collides with pedestrians, bicycles, small motorcycles, etc. during driving, sometimes the lower body of the collided pedestrian, etc. is swept by the front of the vehicle body, and bounces off the hood covering the upper surface of the front of the vehicle body, On the other hand, a secondary collision occurs with a part with high rigidity such as a pillar part. [0003] In Japanese Patent Application Laid-Open No. 2000-264146, a protective device for pedestrians and the like is described: when an automobile collides with a pedestrian, the airbag is inflated along the co...
