Abstract
An airbag system (3) having a two-chamber airbag (4), wherein the main chamber has an impact surface (7) which the vehicle occupant can contact and a support surface (8) with the main chamber (5) supported on an interior fitting (2) of the vehicle. A secondary chamber (11) forms a support cushion for the main chamber (5), the main chamber (5) having a greater volume than the secondary chamber (11). The secondary chamber (11) is located between the support surface (8) and the interior fitting (2).

A first gas generator (16) inflates the main chamber (5) and a second gas generator (17) inflates the secondary chamber (11), wherein both generators (16, 17) or only the first generator (16) can be controlled for inflating the main chamber (5) as desired.
