| Summary: | The invention relates to a lightweight support for bumpers of motor vehicles, formed by an extruded profile, with a plurality of chambers, made of a light metal. It is possible for the lightweight supports themselves to form bumpers or to support a bumper positioned in front of them or, more generally, the front part of a vehicle over the entire vehicle width. For this purpose, they are usually bent into the corresponding shape.
A lightweight support for a bumper is formed by an extruded profile with a plurality of chambers. In order to provide a profile which, along with an extremely low weight, meets all the static requirements, is easy to bend and is suited to the properties of a light-metal alloy, the profile () comprises four walls (), which preferably form an isosceles trapezoid, and two webs (), which are arranged in the interior of the profile, parallel to the side walls () and likewise symmetrically. The side walls () of the support () have stiffening ribs () which are produced in the same operation as the support () is bent. A description is given of the associated process. |
