Improved damping system for lateral vehicle impact with high damping and energy absorption capacity

摘要

Improved system for contention of lateral vehicle impact with a high capacity of contention and of energy absorption, characterized by comprising a vertical post (2) that has a fold or acute dihedral angle (15) placed at a given height in such a manner that its lower segment is vertical and its upper segment, which is an extension of the lower segment, is tilted towards the front, advancing the rail forward towards traffic, and also characterized by having a continuous horizontal non-stressed tie (4) to prevent the post (2) from being released from the system in case of impact, and because it incorporates, between the lower rail (1) and the post (2), an spacer-shock absorbing element (3) comprising a rigid part (19) and a deformable part (20), all of it intended to attain a high capacity to absorb the energy resulting from a vehicle colliding against it, to redirect the vehicle, to decrease the deceleration levels, to gain control over the vehicle during and after impact, and also to decrease the possibility of non-desired post-impact reactions of the vehicle, as well as endowing the system with a high capacity to control the dissipation of the absorbed energy and with a certain ability to deform similarly after each impact of a vehicle.
