A crash management system (″) 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 (″) of bumper beams with at least a first bumper beam (″) and a second bumper beam (″), oriented in said transverse direction Y, said first bumper beam (″) and second bumper beam (″) being vertically spaced wherein said first bumper beam (″) is located above said second bumper beam (″), optionally comprising at least one crash box () connected to at least a bumper beam (″), and comprising at least a connecting element () characterized in that said connecting element () connects said first bumper beam (″) and said second bumper beam (″), and wherein said connecting element () is an extruded hollow profile which extrusion direction (E) is substantially parallel to said vertical direction Z.

Connecting element for improved crash behaviour in a car to car collision

A crash box () comprising a hollow profile () extending along a longitudinal direction (X) and having a crush length (LCB), said hollow profile () having at least two chambers () characterized in that it comprises at least a deformable element (″) contained into at least one chamber () contributing to the energy absorption capability of said crash box ().

Crash box containing a deformable element to extend the capacity of a crash box to absorb impact energy

The invention relates to a bumper () for a motor vehicle, with a cross beam element () exhibiting a back side () designed to be fastened to the motor vehicle with at least one fastening device (), preferably in the form of a crash box, and a front side () lying opposite the back side (), wherein the cross beam element () has at least one hollow chamber () with a closed cross section, and with a reinforcing element (), which extends over part of the length of the cross beam element () and is joined with the cross beam element (). The invention provides that the cross beam element () be designed together with the reinforcing element () as a single-piece extruded part.

Bumper for a motor vehicle with reinforcement and method for manufacturing the bumper

A motor vehicle bumper with a crossmember () in channel form and a front element (), which is mounted in front of said crossmember and is in channel form, said crossmember and front element together forming a pedestrian protection system, characterized in that, in the assembled state, the front element () has a greater overall height (h) than the crossmember (), and the rear part (), which faces the crossmember, of the upper and lower wall regions of said front element are inclined from the horizontal towards the crossmember ().

Motor vehicle bumper with an integrated pedestrian protection system

A bumper with an attachment member to be made thereon for the purpose of mounting the bumper onto longitudinal beams of a vehicle, is such that section walls acting as compressive and tensile struts and a pair of flanking walls joining them form a hollow section. The attachment member is in the form of a hollow section exhibiting at least one side wall and two transverse walls following on therefrom with a length of hollow section with the longitudinal beam. The hollow section is in the form of a push-fit length matching the inner cross-section of the longitudinal beam. The other end region of the attachment member is provided with collar-type parts projecting from their end edges and aligned approximately parallel to the transverse walls. In a use position, the collar-type parts of the attachment member are aligned with the flanking walls of the bumper and are releasably attached to it. The bumper is bolted to the collar-type parts of the attachment member.
