Abstract
A side impact protection device for an occupant of a vehicle includes an air bag which is divided by an interior partition into two chambers situated above one another. The lower chamber interacts with a gas generator. A primary opening having a relatively large cross-section is formed at the partition. So that an optimal functioning of both chambers of the air bag is always ensured during the inflation, at least one other opening with a relatively small cross-section is provided on the partition next to the primary opening situated outside the radiation area of the gas generator. The other opening extends at a distance to the primary opening and acts as a pressure relief valve when the lower chamber of the air bag is inflated.
