Abstract

A cockpit cross beam for a motor vehicle includes at least one structured metal section arranged on the driver's side, wherein the metal section exhibits cross-sectional areas varying in the axial direction and has connection elements for connecting the metal section to other structural parts of a motor vehicle body. A cockpit cross beam that permits variable steering column angles of inclination with identical steering column connection is achieved in that the metal section arranged on the driver's side in each case has rotationally symmetric cross-sectional areas as connection elements at its ends and the cross-sectional areas of the ends have a common rotational axis.

First claim

The invention claimed is:

1. A cockpit cross beam for a motor vehicle, the cockpit cross beam comprising:
a one-piece structured metal section;
wherein the metal section exhibits cross-sectional areas varying in the axial direction;
wherein the metal section has connection elements for connecting the metal section to other structural parts of a motor vehicle body;
wherein the metal section only extends within the region of the driver's side of the cockpit beam;
wherein the metal section has rotationally symmetric cross-sectional areas as connection elements at the ends;
wherein the cross-sectional areas of the ends have a common rotational axis and at least partially a circular contour; and
wherein the metal section has planar parallel lateral surfaces at least within the region of a steering column connection.

2. The cockpit cross beam of claim 1 , wherein the metal section is a closed, structured hollow section.

3. The cockpit cross beam of claim 1 , wherein the metal section has a cross-section running conically in the axial direction.

4. The cockpit cross beam of claim 1 , wherein the metal section has a connection region for struts, in which the upper or lower side of the metal section has an at least partially circular contour.

5. The cockpit cross beam of claim 1 , wherein the metal section has a connection region for struts, in which the upper and lower side of the metal section has an at least partially circular contour.

6. The cockpit cross beam of claim 1 , wherein the structured metal section that extends only within the region of the driver's side of the cockpit beam has first and second conical sections, the structured metal section being positioned between the first and second conical sections, the first conical section increases in diameter when moving in a first direction towards the second conical section and the second conical section increasing in diameter when moving in a second direction, opposite the first direction, towards the first conical section.

7. The cockpit cross beam of claim 1 , wherein the structured metal section has generally hollow shape and the coplanar lateral surfaces are directly provided by the sidewall portions providing the hollow shape of the structured metal section, the connection elements having a different cross-sectional shape than the portion of the structured metal section that provides the coplanar lateral surfaces.

8. The cockpit cross beam of claim 7 , wherein the connection elements and the lateral surfaces are formed from a single cut-out blank to form the one-piece structured metal section.

9. The cockpit cross beam of claim 1 , wherein the metal section in each case has circular cross-sectional areas as connection elements at the ends and the cross sectional areas of the ends are arranged concentrically to each other.

10. The cockpit cross beam of claim 9 , wherein the circular cross-sectional areas are provided at the ends of the metal section by axially extending connection regions.

11. The cockpit cross beam of claim 10 , wherein the connection regions of the metal section have constant cross-sectional areas in the axial direction at the respective ends.

12. A cockpit structure comprising the cockpit cross beam of claim 1 .

13. The cockpit structure of claim 12 , further comprising a vertical strut which connects the metal section to the base region or tunnel region or cowl of a body and has a rotationally symmetric seat to hold one end of the metal section.

14. The cockpit structure of claim 12 , further comprising a steering column console, which is fastened via securing means running perpendicularly to the axial direction of the metal section.

15. The cockpit structure of claim 12 , further comprising a modular seating plate, which serves to hold a steering column console, and the modular seating plate is welded to the metal section.

16. The cockpit structure of claim 12 , further comprising a steering column console, which is fastened via bolts with bushings running perpendicularly to the axial direction of the metal section.

17. The cockpit structure of claim 12 , further comprising a first strut, including a metal section for connecting the metal section of the cockpit cross beam to the bulkhead or the cowl of a vehicle body, wherein the first strut has a connection region for connecting the first strut to the metal section.

18. The cockpit structure of claim 17 , wherein the metal section, at least within the connection region of the first strut, has an at least partially circular contour perpendicular to the axial direction of the metal section and the connection region of the first strut is adapted to this circular contour.

19. The cockpit structure of claim 12 , further comprising a second strut for connecting the metal section to the cowl or the bulkhead.

20. The cockpit structure of claim 19 , wherein the first and the second struts are connected to the bulkhead or the cowl at a common connection point.
