A vehicle airbag system has an airbag which can be deployed in two stages. In a typical accident situation, a first chamber containing a larger quantity of propellant charge is deployed, and a second chamber containing a smaller quantity of propellant charge is deployed after a delay. If a particular accident situation is detected, such as the out-of-position situation or other person-specific and accident-specific variables, a deployment control device decides whether the ignition sequence is optimal, and reverses the sequence if applicable. The delay can also be varied on the basis of the detected variables.

A head protection system for occupants of a motor vehicle has a multi-chamber air bag, which is inflated laterally of the head in the event of a side impact and prevents the displacement of the head. In addition, it protects the head from vehicle body parts that penetrate the occupant department. Via the individual chambers, an L-shape of the air bag can be constructed which is optimal for the desired purpose. In addition, the division into several chambers permits longer and therefore less aggressive inflation times.
