ENERGY-ABSORBING ELEMENT FOR A VEHICLE

摘要

The invention relates to an energy-absorbing element, particularly an energy-absorbing element which is associated with a beam and used in the bumper part of a vehicle, consisting of preferably dual-surface roll-bond panels made of aluminium alloy. Preferably, the bulging areas are distributed in a non-directional, even manner on the panel in the form of pellets in a fire tube-type structure. Preferably, the alloy used is, a structural hardening alloy of the 6000 family, e.g. type 6016 in state T6. The invention also relates to a method for the production of said absorbers, consisting in the manufacture of said roll-bond panels, the forming thereof and, optionally, the assembly thereof in order to obtain a tubular body that makes up said energy observers.
