A longitudinally extending extruded aluminum bumper is constructed and used in a bumper assembly to protect a vehicle from impact. The bumper includes a three wall design, formed by an integrally formed top wall and a bottom wall interconnected by a front vertically extending wall. The top and bottom walls have open ends that are spaced relative to one another to form a longitudinally extending, open-ended channel therebetween. Upwardly extending and downwardly extending flanges are integrally formed with front vertically extending wall and the top and bottom walls of the bumper. The extruded bumper can be attached directly to an end of a vehicle. Impact absorption devices can also be inserted into the longitudinally extending channel of the bumper and abut against the front vertical wall. Welds can be provided in a non-planar manner to connect the impact absorption devices to the bumper.

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 arrangement for a motor vehicle, having an upper main cross member, which is able to be coupled via crash boxes to the motor vehicle, and a lower auxiliary cross member, wherein the main cross member and auxiliary cross member are coupled together via vertical struts. The main cross member and/or the auxiliary cross member and/or the vertical element are supported on the crash box and/or on a longitudinal member via at least one additional support element oriented in the direction of the motor vehicle, wherein the support element is configured in one piece and in a single material with the main cross member or the auxiliary cross member or the vertical element.

A method for manufacturing a vehicle structure member by using a hollow extruded material that has a pair of side plates and a plurality of connecting plates connecting the side plates together and that has a quadrilateral closed section and a longitudinal shape, such that a width dimension of the vehicle structure member, which is a distance between the side plates, varies in a longitudinal direction of the vehicle structure member, the method including: an extrusion molding step of producing the hollow extruded material with the connecting plates each having a bent shape by extrusion molding; and a widening step of increasing the width dimension by increasing the distance between the side plates partially in the longitudinal direction so as to flatten the connecting plates having the bent shape.

An energy absorbing member (20) is formed of an aluminum alloy extruded material having a substantially quadrangular outer shape. Straight portions of a pair of long sides of a quadrangular shape are each segmented into three side walls (21a, 21b, 21c) by two arcuate internal projections (26) that project inward. Vertices of opposing internal projections (26) are joined by a rib (25). Accordingly, the energy absorbing member (20) is configured to have a shape in which three cylindrical portions having hollow portions (24a, 24b, 24c) are joined. Arc-shaped internal projections (23) that each project inward are provided in four corners of the quadrangular shape.

A vehicle body front section structure includes a front side member, an outer side frame member, a linking member, and a reinforcing structure. The outer side frame member is disposed separated from the front side member at a vehicle width direction outer side, has a vehicle front-rear direction rear end connected to an apron section or to a front pillar, and has a vehicle front-rear direction front end side overlapping with a vehicle front-rear direction front end side of the front side member in side view. The linking member links the vehicle front-rear direction front end side of the front side member and the vehicle front-rear direction front end side of the outer side frame member, and is input with a collision load. The reinforcing structure reinforces the outer side frame member at a portion of the outer side frame member overlapping with the front side member in side view.

An impact absorbing device includes an impact absorbing member extending in a vehicle front-rear direction; and a bumper reinforcement that extends in a vehicle width direction and is attached to a front end surface of the impact absorbing member. The bumper reinforcement includes a body portion extending in the vehicle width direction and having a length in a vehicle height direction that is smaller than a length of the impact absorbing member in the vehicle height direction, and a reinforcing portion fixed to the body portion and extending along a portion of the front end surface of the impact absorbing member, the portion being positioned above or below the body portion.

A beam article for a vehicle includes a plurality of separate elongated metal sheets attached together to form generally planar walls of an elongated tubular structure. At least one of the plurality of separate elongated metal sheets has a shear wall that is disposed along a hollow interior of the elongated tubular structure and is attached at opposing walls of the elongated tubular structure. At least one of the plurality of separate elongated metal sheets comprises an edge that abuts a side surface of an adjacent one of the plurality of separate elongated metal sheets to define a non-radiused perpendicular weld corner along the elongated tubular structure.

A vehicle hood covering an underhood object includes an inner surface of the vehicle hood facing the underhood object and spaced from the underhood object, and an outer surface of the vehicle hood opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the vehicle hood. The local energy absorber is a multiply-connected structure. The local energy absorber includes a wall defining an interior surface having symmetry about a central plane normal to the inner surface of the vehicle hood. A plurality of apertures is defined in the wall symmetrically about the central plane to initiate buckling and fracture in the wall during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.

A high-strength aluminum alloy exhibiting excellent stress corrosion cracking resistance and excellent extrudability, and a method for producing an extruded shape using the same are disclosed. The aluminum alloy includes 1.6 to 2.6 mass % of Mg, 6.0 to 7.0 mass % of Zn, 0.5 mass % or less of Cu, and 0.01 to 0.05 mass % of Ti, with the balance being Al and unavoidable impurities.
