Abstract
An airbag device includes an airbag formed with at least one fabric panel and an inflator. The fabric panel includes at least one loop along a perimeter of the fabric panel. The inflator is a dual stage inflator configured to generate inflation gas during a first inflation stage and a second inflation stage to inflate the airbag. The airbag also includes a tether configured to help control the shape of the airbag when the airbag is inflating, the tether being positioned through the opening or loop when the airbag is in an uninflated state. The tether is severed by heat and/or pressure from inflation gases during the second stage inflation.
