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.
Claims15
A mechanical device forming an elongated structural element of a vehicle, intended to at least partially absorb some impacts, comprising:
- a profiled or tubular elongate part of generally polygonal cross-section;
- a first end part mounted at a first end of the elongate part, at an angle that is substantially perpendicular to the axis of the elongate part, the first end part configured to be fixed to other elements of the vehicle,
- wherein close to its first end, the elongate part comprises cut-outs that create adjusted zones or edges in the vicinity of edges of its cross-section,
- wherein between the elongate part and the first end part a rigid fixing holds the adjusted zones substantially bearing directly on the first end part, and
- wherein the adjusted zones are dimensioned so as to withstand compressive forces and a tilting torque during impact, and
- wherein the other elements of the vehicle fixed to the first end part includes either a crash cushion, or a connecting bar extending to another end part mounted to another elongate part.
