Abstract

A vehicle front structure includes a bumper beam formed as a hollow body having open ends, and elongation members received within the open ends and extending laterally outward.

First claim

The invention claimed is:

1. A vehicle front structure comprising:
a bumper beam formed by a front wall and a rear wall defining a hollow body having first and second open ends, wherein the bumper beam further includes an inner wall extending from the rear wall into the hollow body at the first open end, and
an elongation member with first and second member ends respectively inserted into said first and second open ends of the bumper beam and extending therefrom, the elongation member defining a longitudinal slit extending from the first member end that engages the inner wall when the first member end is inserted into the first open end of the bumper beam.

2. The vehicle front structure of claim 1 , wherein the bumper beam is an extrusion profile.

3. The vehicle front structure of claim 1 , wherein the elongation members are extrusion profiles.

4. The vehicle front structure of claim 1 , wherein the elongation members have a horizontal symmetry plane.

5. The vehicle front structure of claim 1 , wherein at least one of said bumper beam and said elongation members is made of light metal.

6. The vehicle front structure of claim 1 , wherein the bumper beam comprises at least two compartments separated by a partition wall.

7. The vehicle front structure of claim 1 , wherein each elongation member has at least three compartments, the width of a central one of said compartments corresponding to a thickness of the partition wall.

8. The vehicle front structure of claim 1 , wherein the elongation members are curved more strongly than the bumper beam.

9. The vehicle front structure of claim 1 , wherein the bumper beam comprises a connecting member configured to secure the bumper beam to a longitudinal chassis beam in a region where the bumper beam and the elongation members overlap.

10. The vehicle front structure of claim 9 , wherein the connecting member extends across a wall of the bumper beam and fixes the elongation members to the longitudinal chassis beams.

11. The vehicle front structure of claim 9 , wherein a support is configured to connect an end portion of one of said elongation members which faces away from the bumper beam to one of said longitudinal chassis beams.
