An airbag includes: a bag body forming the outer peripheral wall; and a regulating member disposed on an outer peripheral side of the bag body at a time of inflation completion of the bag body. The regulating member is configured so as to be able to regulate the bag body so that an area ranging from the vicinity of a joint portion for mutually joining the outer peripheral edge of the vehicle body side panel and the outer peripheral edge of the occupant side panel to a side of the gas inflow port at the time of inflation completion of the airbag is made smaller in external dimensions and reduced in size than an area at a time of free inflation state of the bag body.

Airbag

A side airbag apparatus includes an inflator, an airbag body that is configured to be deployed and inflated by inflation gas supplied from the inflator, and an inflated-dimension limiter arranged inside the airbag body. The inflated-dimension limiter is joined to the airbag body by a front joint portion provided at the front end of the inflated-dimension limiter. The inflated-dimension limiter is also joined, by a rear joint portion provided at the rear end of the inflated-dimension limiter, to a portion of the airbag body that is behind a section of the airbag body to which the inflated-dimension limiter is joined by the front joint portion. The dimension between the uppermost end and the lowermost end of the front joint portion is set to be different from the dimension between the uppermost end and the lowermost end of the rear joint portion.
