Abstract: A bumper for a motor vehicle includes a cross member which is made of light metal alloy and configured as hollow profile to define an interior space and which has a top beam and a bottom beam, with the top beam and/or bottom beam having a recess defined by a marginal area in the form of a collar oriented into an interior space of the cross member. Arranged at an end of the cross member is a crash box formed with a flange sized to overlap at least one region of the cross member in motor vehicle longitudinal direction. A spacer is arranged in the interior space of the cross member and has a chamfer for formfitting engagement by the collar. A fastener is configured for passage of the recess and thereby extending in a motor vehicle vertical direction through the flange of each crash box and the spacer.

Abstract: A bumper arrangement for a motor vehicle includes a bumper arrangement for a motor vehicle, including a cross member made of a lightweight metal and constructed as multi-chamber section which has at least one front chamber and at least one main chamber, wherein the front chamber is arranged in front of the main chamber in longitudinal direction of the motor vehicle, wherein the main chamber has a greater cross sectional surface than the at least one front chamber, wherein the cross member has a front side facing in a driving direction of the motor vehicle and a rear side facing away from the driving direction, wherein the front side has a height in vertical direction of the motor vehicle, which is greater than a height of the rear side, wherein at least one wall of the at least one front chamber forms a portion of the front side; and crash boxes arranged in respective end regions of the cross member for coupling the bumper arrangement with the motor vehicle. The cross member can be formed as extruded part.

Abstract: A beam having a gooseneck shape with two gooseneck portions. The beam may have a variety of cross sectional configurations. One such configuration has an upper front wall, a lower front wall, and an offset wall there between. The offset wall may be recessed, or offset away from the body of the beam. Also disclosed is a method of manufacturing the gooseneck beam by positioning a length of a material on a flat surface of a two-cam rotating member; gripping said material with said two-cam rotating member; restraining said length; rotating said two-cam rotating member to form a first and second; and pressing a portion of said material.
