Abstract

A support for a motor vehicle body-in-white includes a straight longitudinal portion that includes at least one cavity which is delimited by walls of the support and inside of which a reinforcing element is accommodated and is fastened in the longitudinal direction of the support. The reinforcing element is force-locked to the support so as to be fastened in the longitudinal direction of the support.

First claim

What is claimed is:

1. A support for a motor vehicle body-in-white, comprising:
a straight longitudinal portion of the support that includes at least one cavity which is delimited by walls of the support;
a reinforcing element received and secured in the straight longitudinal portion of the support in the at least one cavity; and
a plurality of supporting walls, wherein each of the plurality of supporting walls protrudes at a respective corner of the at least one cavity from a respective joining between the walls of the support and extends from the walls at an angle to the walls, wherein the reinforcing element is held in the at least one cavity by a force-fit engagement with the plurality of supporting walls.

2. The support according to claim 1 , wherein the support is an extruded profile.

3. The support according to claim 2 , wherein the extruded profile is formed of an aluminum alloy or of fiber reinforced plastic.

4. The support according to claim 1 , wherein the support is configured as a side sill of a vehicle.

5. The support according to claim 1 , wherein the reinforcing element is configured as a reinforcing tube.

6. The support according to claim 1 , wherein the plurality of supporting walls extend in a direction of a central axis of the reinforcing tube.

7. The support according to claim 1 , wherein the reinforcing element is configured as a honeycomb structure.

8. The support according to claim 4 , wherein the reinforcing element is configured as a honeycomb structure.

9. The support according to claim 7 , wherein respective cavities of the honeycomb structure extend in a transverse direction of the support.

10. The support according to claim 1 , further comprising:
guide elements provided on the walls of the support, wherein
the guide elements cooperate with corresponding guide elements of the reinforcing element such that the reinforcing element is movable in a longitudinal direction of the support into the cavity via the cooperating guide elements.

11. A method of reinforcing a support for a motor vehicle body-in-white, the method comprising the acts of:
providing a support with a straight longitudinal portion that includes at least one cavity delimited by walls of the support;
providing a reinforcing element configured to be received inside the cavity; and
force-fit engaging the reinforcing element in a longitudinal direction of the support in the cavity so as connect the reinforcing element to the support, wherein the force-fit engaging is between the reinforcing element and a plurality of supporting walls of the support, wherein each of the plurality of supporting walls protrudes at a respective corner of the at least one cavity from a respective joining between the walls of the support and extends from the walls at an angle to the walls.

12. The method according to claim 10 , wherein the act of providing the support further comprises extruding the support from an aluminum alloy or fiber reinforced plastic material.

13. The method according to claim. 11 , wherein the act of providing the reinforcing element comprises the act of forming the reinforcing element as a reinforcing tube.

14. The method according to claim 11 , wherein the act of force-fit engaging of the reinforcing element further comprises the act of heating and cooling one or both of the reinforcing element or the support prior to engagement.
