A deformable element for a vehicle, particularly a rail vehicle, comprising a profiled part (CR) disposed between two end plates (AC, AP) and having the form of a tubular box, particularly of polygonal cross section, for dissipating impact energy in the event of longitudinal compression by plastic deformation, and comprising a guide element (FH) disposed parallel to the longitudinal direction of said profiled part (CR), which guide element is fixed to the end plate (AC) remote from the vehicle and is capable of sliding through a through opening (DL) in the end plate (AP) facing the vehicle, wherein the end plate (AP) facing the vehicle has a through opening (DL) which has a shape which permits contactless sliding of said guide element (FH) in the longitudinal direction and lateral inclination of said guide element relative to the longitudinal direction.

L'invention concerne un élément déformable destiné à un véhicule, en particulier à un véhicule ferroviaire. Cet élément comprend une partie profilée (CR) qui est disposée entre deux plaques d'extrémité (AC, AP) et qui se présente sous la forme d'une caisse tubulaire, en particulier de section polygonale, cette partie profilée (CR) servant à dissiper l'énergie de choc en cas d'écrasement longitudinal par déformation plastique. L'élément déformable comprend par ailleurs un élément de guidage (FH) qui est disposé parallèlement à la direction longitudinale de la partie profilée (CR) et qui est relié de manière fixe à la plaque d'extrémité (AC) opposée au véhicule. Selon l'invention, la plaque d'extrémité (AP) faisant face au véhicule présente une ouverture de passage (DL) qui est formée de telle sorte que l'élément de guidage (FH) puisse être introduit sans contact à travers ladite ouverture dans la direction longitudinale et incliné latéralement par rapport à la direction longitudinale.
