A vehicle rear portion structure includes: a center frame that is disposed closer to a center portion of a vehicle in a vehicle width direction than both side portions of the vehicle in the vehicle width direction, that is disposed on a rear side in the vehicle, and that extends in a front-rear direction of the vehicle; and a bumper beam that is disposed on a rear side of the center frame to be next to the center frame, that is disposed at a position which overlaps the center frame when viewed from a front-rear direction, and that is configured to be crushable due to a rear collision load.

A shock absorbing component (a vehicular component having a shock absorbing structure) formed from an aluminum alloy hollow extrusion in an elongated shape includes a collision wall, a non-collision wall, an upper wall, a lower wall, and an inner rib. The collision wall forms a collision surface. The non-collision wall forms a non-collision surface 1B. The upper wall and the lower wall 40 connect the collision wall to the non-collision wall. The shock absorbing component is mounted to a vehicle with a stay (a mounting member) on the non-collision surface. The collision wall and the non-collision wall include joint portions joined to the inner rib. The joint portions of the collision wall and the non-collision wall include a collision wall-side recess formed by recessing the collision wall toward the inner rib in the longitudinal direction of the shock absorbing component and a non-collision wall-side recess formed by recessing the non-collision wall toward the inner rib in the longitudinal direction.

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 shock absorbing member of the present disclosure is a shock absorbing member including a first hollow member (11) and a second hollow member (12) that are made of aluminum alloy and are weld joined to each other, in which a weld material and weld beads (W) do not project from a side on which a joined surface between the first hollow member (11) and the second hollow member (12) is located.

A bumper arrangement includes a cross member and two deformation elements for arrangement between end regions of the cross member and longitudinal members of a motor vehicle. The cross member is hollow with a front and rear walls and upper and lower walls. The front wall has a depression extending in longitudinal direction of the cross member. The depression has a deepest region extending at a distance from the rear wall. The upper and lower walls of the cross member each have in the end regions a further depression which extends in longitudinal direction of the cross member, so that the upper wall and the lower wall are more corrugated in the end regions than in a central region of the cross member, so that the distance between the front wall and the rear wall in the end regions is smaller than in a central region of the cross member.

A bumper reinforcement includes a base portion that extends in a vehicle-width direction, and a protruding portion that is attached to at least one end of the base portion in an up-down direction, and that protrudes in a direction away from the base portion in the up-down direction. A crash box is disposed on a vehicle inner side of the base portion. The protruding portion has at least one of (A) a length in a vehicle front-rear direction that is longer than the length in the vehicle front-rear direction of the base portion, and (B) a plate thickness that is greater than the plate thickness of the base portion.

A bead forming method includes the steps of preparing a bumper stay having a partition wall that partitions an internal space and extends in a longitudinal direction, an elastic body that can be inserted into the bumper stay, and a pusher that presses the elastic body; inserting the elastic body into the bumper stay and arranging the elastic body in the bumper stay so as not to come into contact with the partition wall; and forming a buckling bead by compressing the elastic body in the longitudinal direction of the bumper stay by the pusher to expand the elastic body outward in a radial direction without coming into contact with the partition wall, thereby bulging a part of an outer wall of the bumper stay outward in the radial direction without deforming the partition wall.

A bumper crossmember for a vehicle, with a hollow profile body which has a vehicle frame-side proximal vertical wall and a distal vertical wall which are connected to one another by way of transverse walls and extend along a vertical direction. The transverse walls laterally delimit hollow chambers which are arranged in the hollow profile body. The center longitudinal direction of the hollow chambers are oriented in each case along the vertical direction, and the hollow chambers are open on the end side.

The invention relates to an energy absorption device for a bumper arrangement of a motor vehicle having at least one closed hollow chamber which is configured over its entire longitudinal extent from a bumper-side end to a vehicle-side end, wherein at least one support element is arranged on an outer wall for support on a bumper of a motor vehicle. The invention is characterized in that two support elements are arranged on the outer wall for support on a bumper of a motor vehicle, said support elements being connected together by means of a connecting web over their entire longitudinal extent which faces away from the at least one hollow chamber and which is shorter than the longitudinal extent of the device, wherein the two support elements and the connecting web together with the outer wall form a further hollow chamber extending in the longitudinal extent of the device.
