IMPACT CONTROL ASSEMBLY INCLUDING AN EXTRUDE VEHICLE IMPACTOR

摘要

The invention relates to an impact control assembly comprising a powertrain, a structural part of a motor vehicle capable of moving against the powertrain in the event of an impact, and an impactor (10), this impactor (10) comprising a surface impact (30) and force transmission positioned between the structural part and the powertrain to which it is fixed by fixing means. This impactor (10) is made of aluminum extruded in a given extrusion direction (E) and has two main faces (A, B) perpendicular to the extrusion direction (E). In addition, this impactor (10) comprises a stiffening rib and stress channel (34) extending from and perpendicular to the impact surface (30) and at least two through cells (20) parallel to the direction. extrusion (E) in which are housed the fixing means of the impactor (10).
