Problems solved by technology

[0006] However, in the invention described in Patent Document 1, since the airbag is made of cloth, it is difficult to maintain the deployed state for a long time, and depending on the timing when the pedestrian collides with the front pillar, it may not be able to exert a sufficient impact absorption effect.
[0007] In addition, in the invention described in the above-mentioned Patent Document 2, the structure of the link-type column drive mechanism for movably supporting the column ornament on the column frame member is complicated, and the number of parts increases, which causes cost increase. The problem

Embodiment 1

[0057] Below, based on Figure 1 to Figure 7 A first embodiment of the present invention will be described.

[0058] Such as figure 1 As shown, the rear of the engine hood 11 of the automobile has a front window glass 12, which is arranged to be sandwiched between the left and right edges 12a, 12a of the front window glass 12 and the door glasses 14, 14 of the front doors 13, 13. There are front pillars 15,15.

[0059] Such as figure 2 As shown, the front pillar 15 has a closed cross-section by combining the outer panel 16 located on the outer side of the vehicle body and the inner panel 17 located on the inner side of the vehicle body to form a closed section. Airbag 18. The edge 12a of the windshield 12 is superimposed on the front surfaces of the joints 16c and 17a of the outer panel 16 and the inner panel 17 via a stopper rubber 20 and bonded by an adhesive 21 .

[0060] The airbag 18 formed by folding a metal tube has a decorative portion 18a, a window glass side fo...

Embodiment 2

[0078] Below, based on Figure 8 A second embodiment of the present invention will be described.

[0079] In the first embodiment, the folding density of the window glass side folded portion 18b and the outer panel side folded portion 18c is uniformly set along the inner and outer directions of the vehicle body, but in the second embodiment, the window glass side folded portion 18b and the outer panel side folded portion 18c are uniformly set. The folding density of the panel-side folded portion 18c is set to be small (dense) in the vehicle body inner portion, and set to be dense in the vehicle body outer portion.

[0080] According to the second embodiment, at the initial stage of deployment of the airbag 18, the inner side parts of the window glass side folded part 18b and the outer panel side folded part 18c with a lower folding density are first unfolded, and the outer parts of the vehicle body with a denser folding density are stretched out toward the outer side of the ve...

Embodiment 3～ Embodiment 7

[0082] Below, based on Figure 9 Other embodiments of the vent holes 18f... are described.

[0083] Figure 9A shows the third embodiment of the present invention, in which vent holes 18f... According to this embodiment, in addition to the effects of the first embodiment, by forming the vent hole 18f, the inner side of the window glass side folded portion 18b and the outer panel side folded portion 18c can be easily bent. By bending, the airbag 18 can be easily deployed, and the pressing load when the airbag 18 is folded can be reduced.

[0084] Figure 9 (B) and Figure 9 (C) shows the fourth and fifth embodiments of the present invention, in which vent holes 18f.. .. According to these embodiments, in addition to the functions and effects of the first embodiment, by providing the vent hole 18f..., the outer side of the vehicle body and the vehicle body of the window glass side folded portion 18b and the outer panel side folded portion 18c whose rigidity is reduced are ...

Abstract

The invention provides an airbag device. A metallic airbag (18) is disposed between an edge (12a) of window glass (12) of a vehicle and an outer panel (16) of a front pillar (15) protruding further outward of the vehicle body than the edge (12a). As a result of the configuration, an airbag device can be installed without subjecting the existing vehicle body structure to a large-scale design change, and in addition, the installation of the airbag device does not degrade the external appearance. Also, once expanded, the metallic airbag (18) does not shrink. This enables an inflator (19) having a small capacity to be used to reduce the weight and cost, and in addition, irrespective of the displacement of timing at which the collision of a pedestrian occurs, the airbag device can exhibit stable impact absorbing performance. Also, a part of the airbag (18) is caused to serve, in cooperation with the outer panel (16), as a garnish section (18a) which forms the outer surface of the vehicle body, and as a result, the number of parts and cost are reduced because the garnish section (18a) has a function of the garnish.

Description

technical field [0001] The present invention relates to an airbag device in which a metal airbag is arranged between an edge of a window glass of a vehicle and an outer panel protruding outward from the edge of the vehicle body, and the airbag is moved along the edge by gas generated by an inflator. The edge of the window glass is expanded in a tubular shape to protect pedestrians. Background technique [0002] A folded cloth airbag is housed inside the pillar ornament covering the front surface of the front pillar of the automobile. When a pedestrian collides with a pedestrian, the gas generated by the inflator is supplied to the airbag, whereby the airbag is released from the pillar ornament. The broken gap is developed along the front surface of the front pillar to protect pedestrians, and such a pedestrian protection airbag device is disclosed in Patent Document 1 below. [0003] In addition, the pillar ornament covering the front surface of the front pillar of the auto...
