Abstract

An airbag module for installation in a motor vehicle has an airbag made of an airbag fabric and folded up before being triggered by an inflation device. The airbag fabric has at least one slit forming an adaptive ventilation opening and a retaining strap, which at one end is held releasably on a retainer on the airbag module and at the other end is connected fixedly to the airbag. The slit (11) is cut into the airbag fabric and has two ends configured to prevent the slit (11) from tearing when pressure is applied. The retaining strap is arranged on the inside of the airbag and is guided through a securing loop (17) attached to the airbag fabric opposite the fixed end (14) of the retaining strap across the slit (11) toward the retainer.
