Problems solved by technology

[0004] However, in the existing airbag for head protection, the initial stage of expansion can be completed in a relatively thin state, and when the expansion is completed, the position that needs to be expanded thickly, such as the strut expansion part, has to be improved in terms of the cushioning performance of this position. room for improvement

Embodiment Construction

[0055] Embodiments of the present invention will be described below with reference to the drawings. Such as figure 1 , 2 As shown, the head-protecting airbag 20 according to the embodiment is used in a head-protecting airbag device M mounted on a vehicle V. As shown in FIG. The structure of this airbag device M for head protection includes an airbag 20 , an inflator 12 , mounting brackets 10 and 13 , and an airbag cover 8 . The airbag 20 is folded and accommodated on the upper edge side of the side windows W1 and W2 on the vehicle interior side of the vehicle V from the lower edge side of the front pillar portion FP to the upper side of the rear pillar portion RP through the roof rail RR.

[0056] The structure of the inflator 12, such as figure 1 , 2 As shown, the airbag 20 is formed in a substantially columnar cylindrical shape, and the connection port 22 through which inflation gas flows in the airbag 20 is externally attached, and is connected to the airbag 20 by the c...

Abstract

The head protecting air bag is expanded with the air flowing into the side wall inside the vehicle and the side wall outside the vehicle and developed from folding state over the side wall. The air bag is expanded beside the head of the rider, and the protecting expansion part is provided with temporary connection part to communicate the side wall inside the vehicle and the side wall outside the vehicle. After development, the protecting expansion part has inside pressure increased to separate the side wall inside the vehicle from the side wall outside the vehicle. The air bag of the present invention has fast development in the initial expansion stage and excellent buffering performance after development and expansion.

Description

technical field [0001] The present invention relates to a head protection airbag capable of protecting the head of an occupant by infusing inflation gas from the upper edge side of a side window of a vehicle and inflating it downward. Background technique [0002] Conventionally, an airbag for protecting the head has a structure in which a thin portion is deployed and then inflated thickly (for example, refer to Japanese Patent Application Laid-Open No. 2003-11767). [0003] This kind of airbag is arranged with the protection inflation part that covers the vehicle inner side of the pillar part, and the inflow port for the inflation gas to flow in is arranged on the lower end side. ) on the left and right sides of the ), firstly, let the inflation gas flow in, and expand the prop inflation part in a relatively thin state. The strut swollen portion bulges thickly. [0004] However, in the existing airbag for head protection, the deployment can be completed in a thin state at...
