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.
