MECHANISM FOR ABSORBING KINETIC ENERGY FROM FRONTAL IMPACTS OF VEHICLES AGAINST VEHICLE RESTRAINING SYSTEMS, FOR USING ON THE EDGES AND CENTRAL RESERVATIONS OF ROADWAYS, SUCH AS SHOCK ABSORBERS AND BARRIER ENDS

摘要

The invention relates to a mechanism for absorbing the kinetic energy of a vehicle hitting a restraining system from the front, such as a shock absorber or barrier end, by means of the longitudinal propagation of the plastic deformation of at least one deformable longitudinal metallic profiled element, generated by means of a rigid ram that moves along the deformable profiled element, intercepting part of its cross-section, connected to a structural element of the system that receives and transmits the impact of the vehicle by moving along the restraining system. The deformable profiled element is directly or indirectly fixed in the ground, thereby remaining static during the impact.
