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 vehicle body structure having left and right side frames located on both sides in a vehicle width direction, each side frame including an end on an external force acting side that receives a collision load in a vehicle longitudinal direction acting from outside of a vehicle, and an end on an opposite side of the end on the external force acting side. The side frames are provided with a plurality of fragile portions on left and right sides. The plurality of fragile portions include at least left and right first fragile portions located at the ends on the external force acting side, and left and right second fragile portions located on sides of the ends on the opposite side. An area of each of the left and right first fragile portions is set to be larger than each of areas of the left and right second fragile portions.

Vehicle body structure

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

The present invention relates to a shock absorber system for a vehicle comprising a main unit () adapted to be deformed in the event of an impact with a first energy level and a secondary unit () shorter in length than the main unit (), adapted to be subjected to loads as a complement of the main unit (), after a first deformation phase of the main unit (), when the system receives an impact with a second energy level greater than the first, the secondary unit () being configured to orient the resultant of a force applied on a downstream structure () in a direction not parallel to the longitudinal axis of this downstream structure.
