发明名称	Fastening device for detachably fastening an element to a component fixed to a vehicle
摘要	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.

主权项	1. A fastening device for detachably fastening an element to a component fixed to a motor vehicle, comprising, a holding device that is connected, or can be connected, to the component fixed to the vehicle, a connecting element extending in an axial direction from a first end to a second end, which, in a first state, is connected to a fastening section of the holding device via the first end, and a pyrotechnic charge, which on ignition has the effect that at least the second end of the connecting element is no longer rigidly connected to the fastening section, wherein the holding device forms a bearing, through which the connecting element extends with a section axially spaced apart from the first end, the bearing has at least two bearing surfaces, wherein both bearing surfaces are disposed in different axial locations from the fastening section and arranged on different sides of a peripheral surface of the connecting element, so that the second end of the connecting element, upon separation of the connecting element will tilt in the holding element relative to the longitudinal axis and will tilt away from both of the bearing surfaces after the ignition of the pyrotechnic charge.
