An airbag venting device for controlling an internal pressure of an airbag of a vehicle occupant safety system by releasing inflation gas generated by a gas generator, comprising

• a housing including a first flow orifice facing away from the airbag and a second flow orifice facing the airbag, the housing having an axial total length, the first flow orifice having a first axial opening length and the second flow orifice having a second axial opening length,
• an adjustable closure element assigned to the housing, the closure element, in a closing position, closing and, in an open position, releasing at least one of the first and second flow orifices,
• an actuator device provided at a front end of the housing, the actuator device being configured for activation via a signal received from a controller,
• wherein the actuator device interacts with the closure element to release and/or to close at least one of the first and second flow orifices,
• and wherein the axial total length of the housing is less than 3 times the length of the longer axial opening length of the first and second flow orifices.
