Abstract

A cladding part for a motor vehicle has an external side, and an internal side which is disposed opposite the external side. At least one sensor is disposed on the internal side. The cladding part has at least one main region and at least one functional region, wherein the functional region in terms of oscillations has a lower damping value than the main region. The functional region at least in portions is surrounded by a decoupling region, wherein the cladding part in the decoupling region has a first mechanical rigidity value and in the main region has a second mechanical rigidity value. The first rigidity value is lower than the second rigidity value.

First claim

What is claimed is:

1. A cladding part for a motor vehicle, comprising:
an external side; and
an internal side which is disposed opposite the external side, wherein
at least one sensor is disposed on the internal side,
the cladding part has at least one main region and at least one functional region,
the functional region in terms of oscillations has a lower damping value than the main region,
the functional region at least in portions is surrounded by a decoupling region,
the cladding part in the decoupling region has a first mechanical rigidity value and in the main region has a second mechanical rigidity value, the first rigidity value and the second rigidity value being dissimilar, and
the cladding part in the decoupling region has a first degree of crosslinking and in the main region has a second degree of crosslinking, the first degree of crosslinking and the second degree of crosslinking being dissimilar.

2. The cladding part according to claim 1 , wherein
the cladding part is an external cladding for the motor vehicle.

3. The cladding part according to claim 1 , wherein
the at least one sensor is an ultrasonic sensor, and
the oscillations are ultrasonic oscillations.

4. The cladding part according to claim 1 , wherein
the first rigidity value is lower than the second rigidity value.

5. The cladding part according to claim 1 , wherein
the decoupling region completely surrounds the functional region so as to follow a contour of the functional region.

6. The cladding part according to claim 1 , wherein
a wall thickness of the cladding part is of substantially identical size in a transition region from the decoupling region to the functional region, and/or
the wall thickness of the cladding part is of substantially identical size in a transition region from the decoupling region to the main region.

7. The cladding part according to claim 1 , wherein
the cladding part is configured from a crosslinkable plastics material.

8. The cladding part according to claim 7 , wherein
the crosslinkable plastics material is polypropylene.

9. The cladding part according to claim 1 , wherein
the first degree of crosslinking is lower than the second degree of crosslinking.

10. A cladding part for a motor vehicle, comprising:
an external side; and
an internal side which is disposed opposite the external side, wherein
at least one sensor is disposed on the internal side,
the cladding part has at least one main region and at least one functional region,
the functional region in terms of oscillations has a lower damping value than the main region,
the functional region at least in portions is surrounded by a decoupling region,
the cladding part in the decoupling region has a first mechanical rigidity value and in the main region has a second mechanical rigidity value, the first rigidity value and the second rigidity value being dissimilar, and
the cladding part in the functional region has the same degree of crosslinking and/or the same rigidity value as in the main region.

11. A cladding part for a motor vehicle, comprising:
an external side; and
an internal side which is disposed opposite the external side, wherein
at least one sensor is disposed on the internal side,
the cladding part has at least one main region and at least one functional region,
the functional region in terms of oscillations has a lower damping value than the main region,
the functional region at least in portions is surrounded by a decoupling region,
the cladding part in the decoupling region has a first mechanical rigidity value and in the main region has a second mechanical rigidity value, the first rigidity value and the second rigidity value being dissimilar, and
the cladding part in the functional region has the same degree of crosslinking and/or the same rigidity value as in the decoupling region.
