Abstract

An airbag module having a first nozzle (10) enclosing a first gas compartment (G1), and a first inflator. At least one adaptive ventilation device for the first gas compartment (G1) is provided with a ventilation opening (12) bordered by flexible material and at least one throttle device with a tear seam, which, in a first state, throttles the gas flow more strongly than in a second state. A second cover (44) surrounding a second gas compartment (G2) and a gas source for the second gas compartment (G2) are provided, wherein the tear seam (49) extends through the second gas compartment and, upon filling of the second gas compartment (G2) by the gas source, the seam ruptures and the adaptive ventilation device passes from the first, to the second state.
