FASTENING DEVICE FOR FASTENING AN ASSEMBLY IN AN OPENING OF A WALL OF A VEHICLE

摘要

The invention relates to a fastening device for fastening an assembly in an opening of a wall of a vehicle. The fastening device comprises a support element (2) to be placed on the wall (1) and a retaining element (3) having at least one retaining wing (3.1) for fastening the fastening device in the opening (1.1) of the wall, the retaining element (3) for fastening the fastening device being rotatably arranged relative to the support element (2), i.e. allowing a bayonet-type fastening. In order to be able to mount the assembly without tools, at least one rotary wing (3.2) is arranged on the retaining element (3) and has a contact surface (AF) in the direction of rotation for fastening the fastening device, said contact surface being inclined in the direction of rotation towards said direction of rotation and towards the wall by an angle (a). Generally, more effort is required to remove slanted surfaces from injection molds. Therefore, the rotary wing (3.2) is preferably formed by a wall (3.2.1) that is substantially parallel to the rotation axis and this wall (3.2.1) is reinforced by at least two webs (3.2.2) that are substantially perpendicular thereto but likewise parallel to the rotation axis (A). The webs (3.2.2) extend from the transition zone (3.2.3) between the retaining element and the rotary wing across at least one part of the surface of the wall (3.2.1) of the rotary wing and are beveled towards the contact surface (AF) such that on the whole a contact surface (AF) which is inclined at least in the direction of rotation towards the direction of rotation and towards the wall is obtained.
