Abstract

An airbag arrangement and method includes an airbag module, which has a module housing and an airbag. The airbag is arranged so that it sequentially unfolds in various directions so that it ultimately becomes positioned in front of the passenger. The airbag has two sections, a first chamber and a second chamber. The first chamber inflates first and is forced to travel substantially laterally along the dashboard toward the A-frame, and rests there or the windshield or both. The airbag is twistingly connected relative to the housing so that as the first chamber inflates, it rests against the windshield or the A-frame and applies a torque thereagainst to stably position the first chamber. The first chamber becomes substantially centered about the front seat. Thereafter, the second chamber inflates toward the seat or the passenger seated therein.
