EXTRUDED REINFORCEMENT BEAM HAVING PROGRAMMED DEFORMATION

摘要

Method for producing a reinforcement beam for a vehicle, comprising at least one weak zone arranged in such a way that the bending resistance of the beam is less in said weak zone than in the rest of the beam, characterised in that it comprises, in order, a step (A) of extruding a profile part, a step (B) of cutting the profile part so as to obtain at least one profile segment, a step (C) of locally deforming the segment of the profile part in order to create the weak zone or zones.
