<p>The invention relates to a vehicle structure including a bed that includes two side rails (1), in the form of hollow profile members, and a transverse beam (2) held by the ends in front of said side rails (1), wherein the transverse beam (2) is rigidly connected, on each of the ends thereof, to a piston (21) inserted in a guide tube (12) attached into the front portion of the corresponding side rail (1) and that is forcibly slidable into said guide tube (12). The width of the piston (21) is less than the inner width of the side rail (1) so that the front portion of the side rail (1) can change shape, by means of longitudinal compression, when a shock to the front of the vehicle is applied to the transverse beam (2), thus creating shape-changing folds, in particular inwardly, on the walls of the hollow profile element and making contact with the piston (21) so as to guide the longitudinal compression.</p> |
