Device for fixing a vehicle antenna

1. A device for securing a vehicle antenna to a vehicle body, comprising:

a plurality of projections that engage behind an orifice in the vehicle body for introducing the device on a side of the vehicle body facing away from the vehicle antenna,

wherein:

the projections are situated in such a way that the device, together with the projections, is introducible into the orifice in a predetermined position with respect to the orifice, and

the projections engage behind the orifice by rotation of the projections with respect to the side of the vehicle facing away from the vehicle antenna after introduction into the orifice; and

a body including a first cross-sectional area in the form of a polygonal figure outside an area of the projections, the polygonal figure corresponding to a cross-sectional area of the orifice such that the device is introducible into the orifice outside the area of the projections,

wherein:

the body includes a second cross-sectional area in the area of the projections that also corresponds to the cross-sectional area of the orifice such that the device is also introducible into the orifice in the area of the projections,

the first cross-sectional area and the second cross-sectional are not identical to each other,

the body is in the form of a square,

the first cross-sectional area is approximately square, and

the second cross-sectional area is approximately hexagonal.

2. A device for securing a vehicle antenna to a vehicle body, comprising:

a plurality of projections that engage behind an orifice in the vehicle body for introducing the device on a side of the vehicle body facing away from the vehicle antenna,

wherein:

the projections are situated in such a way that the device, together with the projections, is introducible into the orifice in a predetermined position with respect to the orifice, and

the projections engage behind the orifice by rotation of the projections with respect to the side of the vehicle facing away from the vehicle antenna after introduction into the orifice, and

the projections include two-legged spring elements having legs that are brought together in a direction of introduction of the device into the orifice and that project beyond a first cross-sectional area of the device such that the legs are pressed together by a bordering wall of the orifice on introduction into the orifice and thus pass through the orifice and spring back on a side of the orifice facing away from the vehicle antenna to engage behind the orifice.

3. The device as recited in claim 2 , wherein:

the two-legged spring elements are situated on a clamp surrounding the device in an area of the first cross-sectional area.

4. The device as recited in claim 3 , wherein:

at least one of the two-legged spring elements includes a first leg connected to the clamp and a second leg that is bent away from the first leg.

5. The device as recited in claim 3 , wherein:

at least one of the two-legged spring elements includes a first leg connected to the clamp and a second leg that is cut in from the first leg.

6. A device for securing a vehicle antenna to a vehicle body, comprising:

a plurality of projections that engage behind an orifice in the vehicle body for introducing the device on a side of the vehicle body facing away from the vehicle antenna,

wherein:

the projections are situated in such a way that the device, together with the projections, is introducible into the orifice in a predetermined position with respect to the orifice, and

the projections engage behind the orifice by rotation of the projections with respect to the side of the vehicle facing away from the vehicle antenna after introduction into the orifice;

a mounting plate having a cross-sectional area that extends beyond a cross-sectional area of the orifice on a side of the vehicle body facing the vehicle antenna; and

an elastic material introduced between the mounting plate and the vehicle body.

7. The device as recited in claim 6 , wherein:

the elastic material includes an elastomer material.

8. The device as recited in claim 1 , wherein:

the first cross-sectional area is non-circular.

9. The device as recited in claim 1 , wherein:

the first cross-sectional area is non-perfectly round.

10. The device as recited in claim 1 , wherein:

the first cross-sectional area is polygonal, and

the second cross-sectional area is polygonal with two cropped corners.
