Abstract

A cooling air guide device is provided for a motor vehicle which, viewed in the travel direction of the vehicle, can be situated in front of at least one cooling component of the vehicle and has at least one first guide component, which can be situated on a load-bearing structural part of the vehicle and one second guide component, which is upstream from the first guide component in the travel direction. The second guide component protrudes at least regionally up to a bumper fascia and has a material which is more easily deformable than the first component.

Claims

1. A cooling air guide device for a motor vehicle viewed in a travel direction of the motor vehicle, comprising:

at least one cooling component in which the cooling air guide device is situated in front;

at least one first guide component situated on a load-bearing structural part of the motor vehicle; and

a second guide component upstream from the at least one first guide component in the travel direction,

wherein the second guide component is adapted to protrude at least regionally up to a bumper fascia and the second guide component comprises a material that is more easily deformable than the at least one first guide component.

2. The cooling air guide device according to claim 1, further comprising a bumper girder situated in front of the at least one cooling component in the travel direction and embedded in the second guide component.

3. The cooling air guide device according to claim 1, further comprising at least one deformable damping element situated between a bumper girder and the at least one cooling component.

4. The cooling air guide device according to claim 3, wherein the at least one deformable damping element is implemented as a foam layer that extends at least regionally over a width of the at least one cooling component.

5. The cooling air guide device according to claim 3, wherein a damping element is adapted to transmit a deformation or displacement of the bumper girder oriented opposite to the travel direction in a damped or attenuated form to the at least one cooling component.

6. The cooling air guide device according to claim 2, wherein the bumper girder or a damping element downstream there from are situated so as to b displaceable in relation to the at least one first guide component in a vehicle longitudinal direction.

7. The cooling air guide device according to claim 1, further comprising an upper guide channel lying above a bumper girder and a lower guide channel extending below the bumper girder.

8. The cooling air guide device according to claim 3, further comprising at least two first guide components that are situated spaced apart from one another in a vertical direction by a damping element, and an upper or a lower lateral surface of the damping element that form an upper boundary or a lower boundary of a upper guide channel or a lower guide channel.

9. The cooling air guide device according to claim 1, wherein a separate air intake channel for an internal combustion engine of the motor vehicle is integrated in the at least one first guide component or the second guide component.

10. The cooling air guide device according to claim 1, wherein the second guide component or an air intake channel press essentially airtight against the bumper fascia.

11. A cooling air guide device for a motor vehicle viewed in a travel direction of the motor vehicle, comprising:

at least one cooling component in which the cooling air guide device can be situated;

at least one first guide component that can be situated on a load-bearing structural part of the motor vehicle; and

a second guide component that is upstream from the at least one first guide component in the travel direction;

a damping element situated upstream from the at least one cooling component in the travel direction that coming to rest between the at least one cooling component and a bumper girder in an installed position on the motor vehicle, viewed in a vehicle longitudinal direction, is situated so as to be displaceable in relation to the at least one first guide component.

12. The cooling air guide device according to claim 11, wherein the damping element is adapted to transmit a deformation or displacement of the bumper girder oriented opposite to the travel direction in a damped or attenuated form to the at least one cooling component .

13. A motor vehicle, comprising:

a front structure; and

a cooling air guide device situated on the front structure so as to be displaceable in a vehicle longitudinal direction, the cooling air guide device comprising;

at least one cooling component in which the cooling air guide device is situated in front;

at least one first guide component situated on a load-bearing structural part of the motor vehicle; and

a second guide component upstream from the at least one first guide component in a travel direction,

wherein the second guide component is adapted to protrude at least regionally up to a bumper fascia and the second guide component comprises a material that is more easily deformable than the at least one first guide component.

14. The motor vehicle according to claim 13, further comprising a bumper girder situated in front of the at least one cooling component in the travel direction and embedded in the second guide component.

15. The motor vehicle according to claim 13, further comprising at least one deformable damping element situated between a bumper girder and the at least one cooling component.

16. The motor vehicle according to claim 15, wherein the at least one deformable damping element is implemented as a foam layer that extends at least regionally over a width of the at least one cooling component.

17. The motor vehicle according to claim 15, wherein a damping element is adapted to transmit a deformation or displacement of the bumper girder oriented opposite to the travel direction in a damped or attenuated form to the at least one cooling component.

18. The motor vehicle according to claim 14, wherein the bumper girder or a damping element downstream there from are situated so as to b displaceable in relation to the at least one first guide component in the vehicle longitudinal direction.

19. The motor vehicle according to claim 13, further comprising an upper guide channel lying above a bumper girder and a lower guide channel extending below the bumper girder.

20. The motor vehicle according to claim 15, further comprising at least two first guide components that are situated spaced apart from one another in a vertical direction by a damping element, and an upper or a lower lateral surface of the damping element that form an upper or lower boundary of an upper guide channel or a lower guide channel.
