Abstract
A fastening device for detachably fastening an automotive airbag component. The fastening device has a holding device (10), a connecting element (20) extending from a first end (21a) to a second end (22a), which, is normally connected to a fastening section of the holding device (10), and a pyrotechnic charge, which, on ignition, causes an end (22a) of the connecting element (20) to be detached from the fastening section. The holding device (10) has a bearing through which the connecting element (20) extends with a section spaced from the first end (21a). This bearing has at least two bearing surfaces (16a, 18a) separated differently from the fastening section and arranged on different sides of the connecting element, so that the separated section of the connecting element (20) can tilt in the bearing after the ignition of the pyrotechnic charge.
