The projecting area 112 assigns in contrast 5 the attack 120 with the frame 108 on an opposite side of the recess along the X direction 121 on. Thus, the fastener 105 reliable in the frame 108 can be braced because the first leg 109 along the X direction also against the frame 108 is pressed.

The wind deflector arrangement 100 has a simpler structure and thus an easier assembly compared to conventional wind deflector arrangements. The connection of the wind deflector element 102 and attachment to the frame 108 are together in the fastener 105 integrated. According to embodiments, this also has the above range 119 to connect the vehicle headliner. This means that only a single element can be produced and accordingly only one injection molding tool is required. Possible undercuts are possible, for example, in the injection molding tool with additional slides, and such demolding also enables complex shapes for the fastening element 105 .

For mounting the wind deflector arrangement 100 first become the piping 103 and the fastener 105 on the wind deflector element 102 attached, in particular molded. The wind deflector bracket 107 is on the first piping 103 attached. The wind deflector element 102 comes together with the wind deflector bracket 107 on the frame 108 attached. The frame 108 is made in particular of steel or mostly steel. In addition, according to further exemplary embodiments, the further fastening elements 113 provided for a lateral fixation of the wind deflector element 102 by alternately clipping into the frame 108 or a bearing for the wind deflector bracket 107 to provide.

The integration of the various functions in the fastener 105 enables a shorter tolerance chain, especially since fewer individual manufacturing steps and tools are involved. In addition, fewer components than conventionally required. Less assembly effort can be achieved.
