Abstract: An elongate mechanical device for vehicles, for absorbing impacts, which includes a profiled or tubular elongate part of polygonal cross section, and an end part mounted at one end of the elongate part, at an angle perpendicular to the axis of the elongate part, and intended for fastening to other elements. In the vicinity of its end, the elongate part includes cutouts, which create adjusted regions or faces, in the vicinity of edges of its cross section, and a rigid fastening is provided between the elongate part and the end part that maintains the adjusted regions in direct contact with the end part, the adjusted regions being dimensioned to withstand compressive loads and a tilting torque during impacts.

Abstract: A section of a motor vehicle front low area includes a first extendable elongated part, whose rear end is placed in front of a vehicle structural element embodied in a form of a cradle, whereas the front end thereof is connected to a bar-type structural element of the vehicle by a first connection device. The rear end of the first elongated part is movably mounted in front of the cradle-shaped vehicle structural element. The first connection device includes a connection in a form of a slide bar enabling a substantially longitudinal movement to be carried out and a removable stop member for normally hindering movement up to the removal.
