Abstract:
1. A collapsible strut with controlled deformation for a frame of a road vehicle, comprising: an internally hollow tubular body, which presents a closed transverse section, extending between an inner end and an outer end, which are axially opposite to one another, and fixed in a projecting manner to the frame of the road vehicle at the inner end, and is to deform in a controlled manner in case of crash, collapsing axially, wherein the body has a thickness which axially varies in a continuous manner from the inner end to the outer end that the thickness of the body is continually changing from the inner end to the outer end; wherein the thickness presents an absolute maximum at an intermediate section that is arranged between the outer end and the inner end closer to the inner end; wherein the thickness decreases from the intermediate section towards the inner end and decreases from the intermediate section towards the outer end; wherein the thickness presents an absolute minimum at the outer end and presents a relative minimum, which is higher than the absolute minimum, at the inner end.
