  • Lightweight support for bumpers
    Patent number: 6767650
    Abstract: 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 (1) comprises four walls (2, 3, 5, 6), which preferably form an isosceles trapezoid, and two webs (7, 8), which are arranged in the interior of the profile, parallel to the side walls (5, 6) and likewise symmetrically. The side walls (5, 6) of the support (1) have stiffening ribs (25) which are produced in the same operation as the support (1) is bent. A description is given of the associated process.
