Un ensemble de borne comprend une borne (3) et un support de borne fixe (5) qui sont formés de telle sorte que la borne peut coulisser par rapport au support de borne lors d'un choc par un véhicule, la borne restant dans son orientation d'origine pendant le mouvement de coulissement. L'ensemble de borne comprend également un mécanisme d'absorption d'énergie destiné à absorber l'énergie du véhicule lorsque la borne coulisse par rapport au support de borne, et contribue ainsi à ralentir le véhicule.
