A beam comprising a first portion having a U-shaped cross-section, wherein the U-shape comprises a bottom and a first and a second side wall extending substantially perpendicular to the bottom, and wherein the first and/or the second side wall comprises a first substantially straight portion, a second substantially straight portion and a side transition zone between the first and the second substantially straight portion. The disclosure further relates to bumpers, rocker panels, side impact beams and B-pillars comprising such beams and to vehicles incorporating such components.

Beams with U-shaped cross-section

A rocker () of a vehicle, the vehicle and the rocker () comprising a main elongation axis, a width axis (Y) and a height axis (Z), a lower portion and an upper portion, the rocker () further comprising a central core () comprising a length along the main elongation axis and a height along the height axis (Z); two hollow units () extending along the length and on one side and the other of the central core (), such that one of the units () is closer to the outside of the vehicle () than the other unit (), and a cross-section of the units in the main elongation axis, forms a closed polygon on the length of the central core (); and two flanges () projecting from the lower and upper portions of the rocker ().

Rockers for vehicles and vehicles comprising such rockers

A beam provided with at least one first part that has a main body with an overall U-shaped straight cross-section provided with lateral flanges protruding outwards from the sides of the U, the main body further comprising a bottom part as well as two wings forming the sides of the U. The central portion of the main body defines cells working under tension and under compression, respectively, on either side of a neutral main bending axis formed by two transition zones, which are each located between the U-shaped element and a lateral flange. The bottom part of the main body comprises at least one transition formed by a curvature discontinuity. And at least one wing comprises at least one transition formed by a curvature discontinuity.

Beam for producing a metal framework

A motor vehicle bodywork beam including a main reinforcement having a bottom, two side walls and two flanges substantially parallel to the bottom and a secondary reinforcement. The secondary reinforcement is fixed to the main reinforcement. The main reinforcement and secondary reinforcement are fixed at each side wall level, and of the side walls and/or bottom of the main and/or secondary reinforcement comprise a transition, such that at least a part of the bottom of the secondary reinforcement is in contact with a part of the bottom of the main reinforcement. The bodywork beam has at least one closed cell formed by the main reinforcement and a secondary reinforcement, and the cell has four linear segments formed by the main reinforcement and/or secondary reinforcement, three linear segments covering at least 50% of the corresponding dimension of the cell, so that two segments are oriented transversely to the bottom of the main reinforcement, and the other two segments are substantially perpendicular to said two first segments.
