The invention relates to an airbag module with a first gas space (G1) and an inflator. An adaptive ventilation device for ventilating the first gas space (G1) has at least one ventilation opening (12) and at least one throttle device that throttles more strongly in a first state of the gas flow through the ventilation opening (12) than in a second state. The throttle device comprises a tear seam (49). A second gas space (G2) and a gas source for filling same are provided, wherein the tear seam (49) extends through the second gas space and tears when the second gas space (G2) is filled, such that the ventilation device transitions from a first, throttled state into a second, less throttled state. The tear seam (49) throttles the ventilation opening in the first state by directly connecting a first portion of the edge of the ventilation opening (12) to a second portion of the edge and thus contracts the edge at least in certain portions.
