摘要

An airbag formed of an airbag fabric (10) having a slit-shaped adaptive ventilation opening (11) which in the folded-up state of the airbag is held in at least a partially closed state by an arrester strap (20) having an end overlapping the adaptive ventilation opening (11) and fastened to the airbag fabric (10). The arrester strap (20) is guided through a safety-loop opening (31). The safety-loop opening is formed by a reinforcing blank (13) enclosing the ventilation opening (11) and the opening (31) for the arrester strap (20) is formed by an edge area of the reinforcing blank (31) not connected to the airbag fabric (10), and in that the end of the arrester strap is connected with both the airbag fabric (10) and with the reinforcing blank (13) in an area lying opposite with respect the edge section of the ventilation opening (11) forming the opening (31).
