First Claim
1. An airbag device comprising:
- an inflator;
an airbag having an attachment hole for the inflator, the airbag being accommodated in a folded state around the inflator;
a gas rectifying member that guides gas from the inflator, the gas rectifying member being disposed between the inflator and the accommodated airbag;
a cushion ring disposed near the attachment hole inside the airbag; and
a base plate for fixing the airbag, the base plate being disposed to oppose the cushion ring,wherein the gas rectifying member includes a retained portion retained, together with the airbag, between the cushion ring and the base plate, and a free-standing tubular gas-flow guide portion standing upright from the retained portion, andwherein the retained portion and the gas-flow guide portion are formed as a single part from a base fabric.

Abstract
The operation efficiency is improved by enabling a gas rectifying member of an airbag device to be easily disposed in a folded airbag. An airbag in a folded state is accommodated around an inflator of an airbag device, and a gas rectifying member (12) for guiding gas is disposed between the airbag and the inflator surrounded by the airbag. The gas rectifying member (12) includes a retained portion (12A) retained, together with the airbag, around the inflator and a free-standing tubular gas-flow guide portion (12B) standing upright from the retained portion (12A), which are formed as a single part from a base fabric. The airbag is folded in a state in which the retained portion (12A) is retained inside the airbag. At this time, the gas-flow guide portion (12B) is less likely to be sandwiched between the airbag, because it is standing in the airbag.
