Abstract

A cover device is provided for an engine compartment of a motor vehicle, with at least one, in particular extensive, attenuator, at least a first section of which rests and/or abuts against at least one first engine compartment element situated in the engine compartment, and with at least one fastener, with which the attenuator can be secured or is secured directly or indirectly to the vehicle body, the at least one engine compartment element and/or at least one second engine compartment element situated in or on the engine compartment, in particular in a movable manner.

Claims (31)

1. A cover device for an engine compartment of a motor vehicle, comprising:

an attenuator having a first section that rests against a first engine compartment element situated in the engine compartment; and

a fastener that is configured to at least indirectly secure the attenuator in a movable manner to at least one of a body of the motor vehicle, the first engine compartment element, and a second engine compartment element;

wherein the fastener is configured to form a bearing around a rotational axis about which the attenuator is configured to pivot; and

wherein the attenuator comprises an area of weakened material that stretches from a lateral edge of the attenuator to an opposing lateral edge, which allows the attenuator to bend at least transverse to the area of weakened material.

2. The cover device according to claim 1 , wherein the attenuator is configured to at least partially cover the engine compartment.

3. The cover device according to claim 1 , wherein the attenuator is further defined as at least two spaced apart attenuators that adjoin along the rotational axis.

4. The cover device according to claim 1 , wherein the first engine compartment element comprises a drive unit.

5. The cover device according to claim 1 , wherein the second engine compartment element comprises an area of a water channel on a front wall.

6. A cover device for an engine compartment of a motor vehicle, comprising:

an attenuator having a first section that rests against a first engine compartment element situated in the engine compartment; and

a fastener that is configured to at least indirectly secure the attenuator in a movable manner to at least one of a body of the motor vehicle, the first engine compartment element, and a second engine compartment element;

wherein the fastener is configured to form a bearing around a rotational axis about which the attenuator is configured to pivot; and

wherein the attenuator is flexibly bendable at least transverse to the rotational axis.

7. The cover device according to claim 6 , wherein the attenuator comprises an area of weakened material that stretches from a lateral edge of the attenuator to an opposing lateral edge, which allows the attenuator to bend at least transverse to the area of weakened material.

8. The cover device according to claim 7 , wherein the area of weakened material is configured to essentially run parallel to the rotational axis of the fastener.

9. The cover device according to claim 6 , wherein the area of weakened material is configured to essentially run parallel to the rotational axis of the fastener.

10. The cover device according to claim 6 , wherein the attenuator is configured to at least partially cover the engine compartment.

11. The cover device according to claim 6 , wherein the attenuator is further defined as at least two spaced apart attenuators that adjoin along the rotational axis.

12. The cover device according to claim 6 , wherein the first engine compartment element comprises a drive unit.

13. The cover device according to claim 6 , wherein the second engine compartment element comprises an area of a water channel on a front wall.

14. A cover device for an engine compartment of a motor vehicle, comprising:

an attenuator configured to absorb sound and having a first section that rests against a first engine compartment element situated in the engine compartment; and

a fastener that is configured to at least indirectly secure the attenuator in a movable manner to any of a body of the motor vehicle, the first engine compartment element, and a second engine compartment element;

wherein the fastener is configured to form a bearing around a rotational axis about which the attenuator is configured to pivot; and

wherein the attenuator is further defined as at least two spaced apart attenuators that adjoin along the rotational axis.

15. The cover device according to claim 14 , wherein the attenuator comprises an area of weakened material that stretches from a lateral edge of the attenuator to an opposing lateral edge, which allows the attenuator to bend at least transverse to the area of weakened material.

16. The cover device according to claim 15 , wherein the area of weakened material is configured to essentially run parallel to the rotational axis of the fastener.

17. The cover device according to claim 14 , wherein the attenuator is configured to at least partially cover the engine compartment.

18. The cover device according to claim 14 , wherein the first engine compartment element comprises a drive unit.

19. The cover device according to claim 14 , wherein the second engine compartment element comprises an area of a water channel on a front wall.
