Abstract

The present invention aims to lighten the weight of a structure inhibiting diameter expansion of an airbag as much as possible. An airbag device installed into an instrument panel including a lid portion configured to be torn and a lid-side peripheral wall portion provided to stand on an outer periphery of the lid portion. The airbag device includes: an inflator; an airbag so as to be inflated and deployed in a bag shape by the gas introduced from the inflator; and an outer bag formed of a sheet-like member to be sewn into a three-dimensional shape having an outer-bag-side bottom and an outer-bag-side peripheral wall portion provided on an outer periphery of the outer-bag-side bottom, the outer-bag-side bottom being secured to the inflator, the outer-bag-side peripheral wall portion surrounding the folded airbag and being disposed so as to be sandwiched between the airbag being inflated and deployed and the lid-side peripheral wall portion.

Description

technical field [0001] The present invention relates to an airbag device that inflates and deploys to protect occupants when a vehicle collides or the like. Background technique [0002] The airbag device for the passenger seat is normally installed in the instrument panel. In addition, when a vehicle collides or the like, the airbag cuts a cover provided on the instrument panel and inflates and opens to protect the occupant. [0003] In the above-mentioned airbag device, the airbag is surrounded by a plate made of resin or metal, and the airbag inflates and opens in the direction of cutting the cover in the instrument panel. Therefore, the airbag device tends to increase in weight. [0004] For this reason, Patent Document 1 discloses an airbag module in which an unloading device for fixing an inflator device is formed with fabric or the like, the unloading device is fixed on a square frame-shaped flange formed of metal or the like, and the flange is mounted on the in th...
