Abstract
An impact beam and a method of producing the impact beam for a motor vehicle is disclosed. A light metal profile with an extrusion width is produced by flattening the light metal profile to a working width and cutting to length to form semi-finished products. The semi-finished products are subjected to further treatment by press-forming techniques to form the impact beam. The impact beam has a longitudinal length which extends transversely to the direction of extrusion of the light metal profile.
Claims14
An impact beam for a motor vehicle, configured as an elongated shaped component and produced from an extruded light metal profile, wherein
- the impact beam has at least two longitudinal portions in a longitudinal direction thereof with different wall thicknesses from one another,
- the light metal profile is extruded in a direction of extrusion transversely to the longitudinal direction of the impact beam and is shaped after the extrusion,
- the impact beam is elongated in the longitudinal direction at an angle between 80° and 100° relative to the direction of extrusion,
- the impact beam has, at least in sections along a length of the impact beam, one of a C-shaped, U-shaped, W-shaped or hat-shaped open hollow cross-sectional profile, and
- the impact beam has an arcuate curvature over the length of the impact beam.
