Fastening device for fastening an assembly in an opening of a wall of a vehicle

摘要

A fastening device for fastening an assembly in an opening of a wall of a vehicle includes a supporting element to be placed on the vehicle wall and a retaining element having at least one retaining wing that fastens the device in the vehicle wall opening. The retaining element is rotatable relative to the supporting element between fastened and unfastened positions. For a tool-free mounting and fastening, the retaining element further includes a graspable rotating wing that has a grasping surface which is inclined at an angle in the direction of rotation, whereby the manual grasping force applied by the installer exerts a force component in a rotational direction to rotate the retaining element, and a force component in an axial direction to press the fastening device against the vehicle wall. Preferably the wing includes a wing wall and reinforcing webs.

主权项

1. A fastening device for fastening an assembly in an opening of a vehicle wall of a vehicle, wherein the fastening device has:
a supporting element configured and arranged to be placed on the vehicle wall; and a retaining element having at least one retaining wing configured and arranged for fastening the fastening device in the opening of the vehicle wall, wherein the retaining element is rotatably arranged to rotate about a rotation axis relative to the supporting element to be rotatable in a rotation direction for fastening the fastening device; characterized in that at least one rotating wing is arranged on the retaining element and has a grasping surface that is inclined toward the rotation direction, the rotating wing comprises a wing wall that extends essentially parallel to the rotation axis and at least two webs that reinforce the wing wall and that extend essentially perpendicular to the wing wall and essentially parallel to the rotation axis, the webs extend from a transition region between the retaining element and the rotating wing across at least a part of a surface of the wing wall, and the webs are beveled along free edges thereof such that the free edges form the grasping surface that is inclined toward the rotation direction.
