Embodiment Construction

[0027] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0028] exist figure 1 and figure 2 In , symbol 10 represents an airbag. The airbag device including the airbag 10 is a head protection airbag device that protects the head A of an occupant of a bicycle or the like, which is a moving object. In the present embodiment, the airbag device 11 is, for example, an airbag device for motorcycles that is worn around the neck of the occupant. In addition, in the following, the front-rear direction (the direction of arrow FR and the direction of arrow RR), the direction of left and right sides ( figure 1 The indicated arrow L direction and arrow R direction) and the up and down directions (arrow U direction and arrow D direction) are respectively described based on the state of the occupant wearing the airbag device.

[0029] Moreover, this airbag device can also be called an airbag module, so in addition to the above-...

Abstract

The present invention provides an airbag capable of obtaining appropriate protection performance with a simple structure. The airbag (10) protects the head (A) of the occupant by inflating with the introduced gas. The airbag (10) includes a bag-shaped airbag main body (12). A plurality of gas chambers (19) into which gas is respectively introduced are arranged in parallel in the airbag main body (12). In the airbag main body portion (12), one air chamber (19) is connected to at least a part of the other air chambers (19) in an overlapping state.

Description

technical field [0001] The present invention relates to an airbag for protecting the head of an occupant. Background technique [0002] Conventionally, with regard to an airbag device provided with an airbag that introduces gas and inflates and deploys it, there has been disclosed one that covers the head of an occupant of a motorcycle such as a bicycle to protect the head, or that covers and sits on the seat of a car. A head protection airbag device that protects the head of the occupant. For example, an airbag main body used in such an airbag device is provided with a plurality of elongated air cells, and these air cells are arranged in parallel. In addition, the airbag main body is formed in an inflated shape along the rounded corners of the occupant's head by connecting the side portions of the air cells so that it covers from the back of the head including both sides of the head and extends to the front in the inflated state. Part of the head (for example, refer to Pa...
