Problems solved by technology

Although a configuration has also been proposed, such as the airbag device described in Patent Document 2, in which the outflow of gas is suppressed by pressing the opening and the inflator with a tongue protruding from the opening of the airbag, but even in this In the structure, only part of the opening can be sealed, so there is still room for improvement

Abstract

According to the air bag apparatus, for example, a side air bag apparatus 20, in a mode in which a portion on a side of a connector portion 33 of an inflator 30 is exposed from a cylindrical portion 51 of a retainer 50, the inflator 30 is contained in the retainer 50. Further, an exposed portion of the inflator 30, that is, a portion thereof exposed from the cylindrical portion 51 of the retainer 50 is fastened together with an extended portion 52 substantially in a shape of a half cylinder extended from the cylindrical portion 51 of the retainer 50 by a clamp mechanism 60 in a state of being covered by an extraneous portion of a base cloth extended from an opening portion 41 of the air bag 40.

Description

technical field [0001] The present invention relates to an airbag device in which an inflator constituting a gas generating source is mounted inside an airbag, and the airbag is inflated and deployed by gas ejected from the inflator. Background technique [0002] In the prior art, such an airbag is as described in Patent Document 1. That is, according to this airbag device, first, a cylindrical holder having a diameter slightly larger than that of the inflator is arranged inside the airbag. One longitudinal end of the holder is exposed to the outside of the airbag through an opening formed in the airbag, and the inflator is inserted into the holder in a stored state. Further, the inflator is fixed to the end of the holder protruding from the airbag by calking. Arranging the inflator in the airbag in this manner prevents damage to the airbag during the operation of compressing the inflator.
