Abstract:
1. A connecting rod comprising two rod elements which are coaxial with a longitudinal axis, are non-contacting and are offset along the longitudinal axis, and an energy-absorption means that absorbs energy by plastic deformation, wherein the energy-absorption means comprises: a hollow tube with an axis coaxial with the longitudinal axis and with a wall which is able to deform plastically in buckling when the hollow tube is subjected to a compressive force directed in the direction of the longitudinal axis, and exceeding a certain threshold, a pin, coaxial with the longitudinal axis, each axial end of the pin being limited in displacement away from a respective one of the rod elements in the event of tensile forces applied to the connecting rod, a sleeve fitting over the two facing axial ends of the rod elements which are positioned one on each side of the energy-absorption means, the sleeve being able to slide with respect to one rod element in order to allow at least one of the hollow tube and the pin to deform and to act as an energy absorber, the sleeve making it possible to limit a range of deformation of the energy absorption means so that a breaking point of the energy-absorption means is not reached, wherein the sleeve comprises an oblong hole capable of accommodating an end stop secured to at least one of the two rod elements with respect to which the sleeve can slide.
