Abstract

A structural component, in particular for a vehicle, includes a beam and at least one energy absorption device which is disposed on a portion of the outer surface of the beam. The beam is profiled and has at least one inner chamber.

First claim

What is claimed is:

1. A structural component, comprising:
a beam; and
an energy absorption device;
wherein the beam is profiled and has a first inner chamber that is bounded by a first vertically extending wall of the beam and a second vertically extending wall of the beam, wherein the energy absorption device comprises a plurality of crush elements, wherein the plurality of crush elements are disposed in a region of an outer surface of the beam, wherein the region of the outer surface of the beam is laterally surrounded on a first side and a second side by respective projecting walls of the beam, and wherein the respective projecting walls of the beam and the beam are monolithically formed in one piece;
wherein the structural component is a body component of a vehicle.

2. The structural component as claimed in claim 1 , wherein the beam is formed from fiber-reinforced plastic.

3. The structural component as claimed in claim 2 , wherein the fiber-reinforced plastic is glass- and/or carbon-fiber-reinforced plastic.

4. The structural component as claimed in claim 1 , wherein the energy absorption device degrades an energy/force acting on the energy absorption device by mechanical disintegration.

5. The structural component as claimed in claim 4 , wherein the mechanical disintegration is crumbling.

6. The structural component as claimed in claim 1 , wherein the energy absorption device is formed from glass- and/or carbon-fiber-reinforced plastic.

7. The structural component as claimed in claim 6 , wherein reinforcing fibers disposed in the energy absorption device have a respective longitudinal direction oriented substantially perpendicular to the outer surface of the beam.

8. The structural component as claimed in claim 1 , wherein the beam is a pultruded profile.

9. The structural component as claimed in claim 1 further comprising a first filling element, wherein the first filling element is disposed in the first inner chamber.

10. The structural component as claimed in claim 9 , wherein the first filling element is a foam core or a honeycomb core or a core of solid material.

11. The structural component as claimed in claim 1 further comprising a second inner chamber that is bounded by the first vertically extending wall of the beam and the second vertically extending wall of the beam, wherein a web of the beam that extends between the first vertically extending wall of the beam and the second vertically extending wall of the beam separates the first inner chamber from the second inner chamber.

12. The structural component as claimed in claim 11 further comprising a second filling element, wherein the second filling element is disposed in the second inner chamber.

13. The structural component as claimed in claim 12 , wherein the second filling element is a foam core or a honeycomb core or a core of solid material.
