Abstract

An airbag module including a first casing enclosing a first gas space, a first inflator and a control device for controlling ventilation of the first gas space or the shape of the first casing. The control device includes a second casing (42) enclosing a second gas space and a gas source. The second gas space is bordered by a permanent edge connection, and further includes a control element such as a strap (60), whose first end is connected to the first casing and whose second end is sewn to the second casing (42) by a tear seam (49), and is decoupled from the second casing (42) upon filling of the second gas space. The tear seam (49) touches or intersects the edge connection at two points so that the tear seam divides the second gas space into two regions (43a, 43b).
