Abstract

An airbag arrangement for a vehicle occupant restraining system including at least one inflatable airbag and an inflating device. The airbag includes a first inflatable area which extends in the inflated status of the airbag in the area of a first body region of the vehicle occupant, and a second inflatable area, which extends in the inflated status of the airbag in the area of a second body region of the vehicle occupant. The first inflatable area has a larger thickness vertical to the main extension plane of the airbag than the second inflatable area. The inflating device and the airbag are designed for inflating the first inflatable area of the airbag to such a high internal pressure that during the impact of the occupant on the airbag a force is exerted onto the first body region of the vehicle occupant which sets the occupant into a tilting motion.
