Abstract

A bumper arrangement for a motor vehicle, having an upper main crossmember, which is able to be coupled to the motor vehicle by way of crash boxes, and a lower auxiliary crossmember, wherein main crossmember and auxiliary crossmember are coupled to one another by way of vertical struts. The main crossmember and the auxiliary crossmember run so as to be curved about the vertical axis at least in certain portions, wherein main crossmember and auxiliary crossmember have different radii of curvature from one another, and/or in that the auxiliary crossmember is set back with respect to the main crossmember in a motor vehicle longitudinal direction in the direction directed toward the motor vehicle, and/or in that the auxiliary crossmember has a central portion which is offset in relation to the vertical direction.

First claim

The invention claimed is:

1. A bumper arrangement for a vehicle comprising:
an upper main crossmember, wherein the upper main cross member is able to be coupled via crash boxes to the vehicle, and
a lower auxiliary crossmember, wherein the upper main crossmember and the lower auxiliary crossmember are integrally connected together by a vertical strut,
the upper main crossmember and the lower auxiliary crossmember extend in a vertical direction of the vehicle,
the upper main crossmember and the lower auxiliary crossmember have different radii of curvature from one another, and
the lower auxiliary crossmember is set back completely with respect to the upper main crossmember in a longitudinal direction of the vehicle, and
the lower auxiliary crossmember further comprises longitudinal members, and the longitudinal members are able to support the lower auxiliary crossmember on the vehicle.

2. The bumper arrangement according to claim 1 , wherein the upper main crossmember and the lower auxiliary crossmember are a press-formed component.

3. The bumper arrangement according to claim 1 , wherein the upper main crossmember and the lower auxiliary crossmember together form an extruded profile.

4. The bumper arrangement according to claim 1 , wherein the vertical strut is U-shaped in a cross section.

5. The bumper arrangement according to claim 1 , wherein the upper main crossmember has an indentation configured to be initially deformed when a force or a load is applied to the vehicle in the longitudinal direction.

6. The bumper arrangement according to claim 1 , wherein the lower auxiliary crossmember is able to be coupled to the crash boxes.

7. The bumper arrangement according to claim 1 , wherein the upper main crossmember is supported on the lower auxiliary crossmember by a support element configured to support the upper main crossmember and the auxiliary crossmember on the crash boxes.

8. The bumper arrangement according to claim 7 , wherein the integral component further comprises the support element.

9. The bumper arrangement according to claim 7 , wherein the support element is on a side portion or a lower portion of the crash boxes.

10. The bumper arrangement according to claim 1 , wherein a first outer end of the upper main cross member is coupled to a second outer end of the lower auxiliary cross member by the vertical strut, and the vertical strut is configured to support a front wheel of the vehicle in the longitudinal direction of the vehicle.

11. The bumper arrangement according to claim 1 , wherein the vertical strut comprises a plurality of vertical struts that connect the upper main crossmember to the lower auxiliary crossmember.

12. The bumper arrangement according to claim 1 , wherein each of the upper main crossmember and the lower auxiliary crossmember comprises a steel alloy.

13. The bumper arrangement according to claim 1 , wherein each of the upper main crossmember and the lower auxiliary crossmember comprises a light metal alloy.

14. The bumper arrangement according to claim 1 , wherein the vertical strut is C-shaped in a cross section.

15. The bumper arrangement according to claim 1 , wherein the vertical strut is hat-shaped in a cross section.

16. A bumper arrangement for a vehicle comprising:
an upper main crossmember, wherein the upper main cross member is able to be coupled via crash boxes to the vehicle, and
a lower auxiliary crossmember, wherein the upper main crossmember and the lower auxiliary crossmember are integrally connected together by a vertical strut,
the upper main crossmember and the lower auxiliary crossmember extend in a vertical direction of the vehicle,
the upper main crossmember and the lower auxiliary crossmember have different radii of curvature from one another, and
the lower auxiliary crossmember is set back with respect to the upper main crossmember in a longitudinal direction of the vehicle, and
the lower auxiliary crossmember further comprises longitudinal members, and the longitudinal members are able to support the lower auxiliary crossmember on the vehicle,
wherein the upper main crossmember and the lower auxiliary crossmember together form an extruded profile.
