Abstract

A crash management system (1, 1′, 1″) for a front part of a vehicle, oriented in a local referential, having a longitudinal direction X a transverse direction Y perpendicular to the longitudinal direction X and a vertical direction Z perpendicular to the plane defined by said directions X and Y, comprising an assembly (2, 2′, 2″) of bumper beams with at least a first bumper beam (3, 3′, 3″) and a second bumper beam (4, 4′, 4″), oriented in said transverse direction Y, said first bumper beam (3, 3′, 3″) and second bumper beam (4, 4′, 4″) being vertically spaced wherein said first bumper beam (3, 3′, 3″) is located above said second bumper beam (4, 4′, 4″), optionally comprising at least one crash box (5, 6) connected to at least a bumper beam (3, 3′, 3″, 4, 4′, 4″), and comprising at least a connecting element (100, 200,300, 400, 500) characterized in that said connecting element (100, 200,300, 400, 500) connects said first bumper beam (3, 3′, 3″) and said second bumper beam (4, 4′, 4″), and wherein said connecting element (100, 200, 300, 400, 500) is an extruded hollow profile which extrusion direction (E) is substantially parallel to said vertical direction Z.
