A method for warm forming an aluminum beam, such as an aluminum component for a vehicle, includes providing an extruded aluminum beam with a hollow cross-sectional shape. A portion of a forming die is heated to a desired temperature, so as to heat a portion of the aluminum beam in the die to a temperature below the artificial aging temperature of the aluminum beam. The heated aluminum beam is deformed to a desired shape with the die in a direction transverse to a length of the aluminum beam.

A bumper device for a vehicle is arranged on one of a front side and a rear side of a vehicle cabin to extend in a vehicle width direction. The bumper device for a vehicle includes: a tubular portion, which is made of metal and integrally formed so as to have a tubular shape extending in the vehicle width direction; and a reinforcing member, which is formed so as to have a plate-like shape extending in the vehicle width direction along an inner surface of the tubular portion. A foamed resin charged into the tubular portion is foamed to be increased in volume, to thereby fix the reinforcing member inside the tubular portion.

A bumper reinforcement beam includes sheets pre-formed to have integral features and to have a final beam shape with non-radiused corners and optimal impact properties, including beams with constant or varied cross-sectional shapes, and beams made of steel, aluminum, or hybrid materials or combinations of material, all of which allow minimization of weight. The non-radiused corners offer excellent impact strength and properties. Beam impact properties can be improved or locally tuned for particular functional requirements by material selection, or by adding an internal reinforcement on an inside center of the front wall, or by localized annealing of the welds to minimize stress risers, or by localized features and shapes. The sheets can be welded using welding processes that provide low heat-affected-zones around the weld or by localized annealing, thus minimizing any adverse effect of welding.

A vehicle body component for a motor vehicle is described, wherein the component is metallurgically connected to at least one other component, wherein the components have a flat contact area with each other, wherein one of the components is constructed as a solder-plated sheet part, and the metallurgical connection is brought about by a furnace soldering procedure. In particular, the vehicle body component is constructed as a bumper consisting of a bumper strut (SFT) extending substantially over the vehicle width and of at least one carrier (T) that carries the bumper strut (SFT) opposite the vehicle body, wherein at least one of the components is a solder-plated sheet part.

A bumper reinforcement includes a body part extending in a vehicle width direction, and a terminal part, which extends in the vehicle width direction, is attached to an end part of the body part in a longitudinal direction, and is joined to the body part in a state of being superimposed on the end part of the body part. Rigidity of the end part of the body part in the longitudinal direction is lower than rigidity of a center part of the body part in the longitudinal direction.

A bumper reinforcement composed of a hollow shape material includes: a rear wall; an upper wall; a lower wall; a front wall; a partition wall located between the rear wall and the front wall and extending from the upper wall to the lower wall; an upper support wall and a lower support wall located between the upper wall and the lower wall and extending from the rear wall to the partition wall; and an intermediate support wall located between the upper wall and the lower wall and extending from the front wall to the partition wall. An intersection of the partition wall with the upper support wall is located above an intersection of the partition wall with the intermediate support wall, and an intersection of the partition wall with the lower support wall is located below the intersection of the partition wall with the intermediate support wall.

A vehicle bumper reinforcement structure to increase energy absorption capacity is provided. The vehicle bumper reinforcement structure comprises a base member extending in the width direction of the vehicle that is attached to the vehicle at both width ends, and a first reinforcement member and a second reinforcement member attached to the base member at a width center of the vehicle. Widths of the reinforcement members are differentiated in such a manner to cause fracture of the base member at width ends of the reinforcement members by a predetermined collision impact applied to the width center of the base member.

An impact beam and a method of producing the impact beam for a motor vehicle is disclosed. A light metal profile with an extrusion width is produced by flattening the light metal profile to a working width and cutting to length to form semi-finished products. The semi-finished products are subjected to further treatment by press-forming techniques to form the impact beam. The impact beam has a longitudinal length which extends transversely to the direction of extrusion of the light metal profile.

A bumper structure includes: a bumper reinforcement including: a hollow body portion extending in a vehicle width direction of a vehicle; and an extending portion arranged on one end portion of the hollow body portion in a longitudinal direction of the hollow body portion; and a side member, which is formed to extend in a vehicle front-and-rear direction of the vehicle, and is configured to support one end portion of the bumper reinforcement in a longitudinal direction of the bumper reinforcement. The extending portion includes: a proximal end portion to be sandwiched between the one end portion of the hollow body portion in the longitudinal direction of the hollow body portion and one end portion of the side member in a longitudinal direction of the side member; and a protruding portion formed to extend outward from the proximal end portion in the vehicle width direction. The side member includes a projecting portion protruding outward in the vehicle width direction. When an object collides against one end portion of the vehicle in the vehicle width direction to break the one end portion of the side member in the longitudinal direction of the side member, the protruding portion of the extending portion is abuttable against the projecting portion of the side member.

An impact absorbing portion and a bumper reinforcement are formed in one piece, so an intermediate member for connecting the impact absorbing portion to the bumper reinforcement is no longer necessary. Therefore, the generation of stress concentration is able to be inhibited. As a result, load transmission efficiency with which a load is transmitted from the bumper reinforcement to the impact absorbing portion is able to be improved.
