Airbag System for Passenger Protection
First Claim
1. An airbag system for protection of an occupant of a motor vehicle, comprising an inflatable airbag with a main chamber forming a protective cushion for the occupant, whereby the main chamber has an impact surface with which the occupant can come in contact, and the main chamber having a support surface with which the main chamber can be supported on an interior equipment device of the motor vehicle, and further comprising a secondary chamber forming a support cushion for the main chamber, whereby the main chamber has a greater volume than that of the secondary chamber, and an inflation device for the airbag, the airbag system adapted to be arranged on the interior equipment device in such a manner that the inflatable main chamber can exit from an exit opening on the interior equipment device, on which the support surface of the main chamber can also be supported, the secondary chamber is formed between the support surface and the interior equipment device, the airbag having an overflow protection element between the main chamber and the secondary chamber, and the inflation device includes a first gas generator for the main chamber and a second gas generator for the secondary chamber, whereby both of the first and second gas generators or only the first gas generator can be selectively controlled for inflating the main chamber.

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). The airbag (4) has an overflow protective element (24) between the main and secondary chambers (11). 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.
