Abstract

A deformable element includes a profiled tube having a rectangular cross-section, and a plate which closes the profiled tube at one end, where a bracket is fastened between opposite sides of the profiled tube at the end of the profiled tube that is closed by the plate.

First claim

The invention claimed is:

1. A water-tight deformable element, comprising:
a profiled tube having a rectangular cross-section;
a continuously planar plate which closes the profiled tube at a first end of the tube; and
a bracket formed to match the rectangular cross-section of the profiled tube and having a repeatedly curved shape which is formed in a double s-shape, said bracket being axially aligned with the profiled tube and the continuously planar plate, oriented away from the profiled tube and directly fastened to and terminating at the first end of the profiled tube which is closed by the continuously formed planar plate to form the water-tight deformable element.

2. The deformable element as claimed in claim 1 , wherein the profiled tube, the plate and the bracket are each welded together.

3. The deformable element as claimed in claim 2 , wherein the profiled tube is configured to fasten to a support component at a second end of the profiled tube facing away from the bracket.

4. The deformable element as claimed in claim 1 , wherein the profiled tube is configured to fasten to a support component at a second end of the profiled tube facing away from the bracket.

5. The deformable element as claimed in claim 4 , wherein the profiled tube is formed to produce a welding connection with the support component.

6. The deformable element as claimed in claim 4 , wherein the profiled tube is formed to produce a screw connection with the support component.

7. The deformable element as claimed in claim 1 , wherein the bracket is manufactured from sheet metal and follows an essentially U-shaped course between fastening points on the profiled tube.

8. The deformable element as claimed in claim 1 , wherein the bracket is manufactured from sheet metal and follows a form between fastening points on the profiled tube which has a convex section, followed by a concave section, followed by a convex section.

9. The deformable element as claimed in claim 8 , wherein a peak of the concave section is set at a distance from the plate.
