摘要

The module (3) has an airbag (5) unfolded between a vehicle seat (1) and a door lining during side collision. The airbag is formed with chest and head chambers (7, 9) that are fluidically connected with each other by an overflow opening (11). The head chamber includes an air discharge opening (13) that adjusts air bag hardness when the module is activated. The chest chamber includes an air discharge opening (15). A flow guidance section (10) guides gas flow into the head chamber to a theoretically predetermined head impact area (12) when the module is activated.
