Lateral impact containment system for vehicles, with high energy absorption and containment capacity

A shock absorbing system of high contention and energy absorption capacity to contain a vehicular impact, the system comprising:

• a plurality of posts, each post having a strut, a frontal plate and a base plate, said posts affixed to a terrain at regular intervals,
• two or more systems of continuous horizontal rails arranged longitudinally and attached to the frontal plate of the post by a clamp placed on an inner side of each rail,
• the strut of each post being formed by two distinct tubular profiles along a vertical length of the post to define a separating device, one tubular profile in front of and facing the other tubular profile, welded to each other and welded to the frontal plate,
• wherein the tubular profile positioned nearest the frontal plate has a U-shaped cross section defined by a base and a pair of spread wings extending therefrom such that free ends of the spread wings are welded to the frontal plate, and the other tubular profile has a trapezoidal-shaped cross section,
• the cross section of the trapezoidal-shaped tubular profile is constant along its entire length and with a vertical axis of the trapezoidal-shaped tubular profile tilted slightly towards the frontal plate which serves as an area that receives the vehicular impact, while the cross section of the U-shaped tubular profile decreases in width along its length from a bottom of the post to a top in such a manner that its wings reach a maximum width at the bottom which is greater than a width of the wings at the top of the post having a shortest width, and
• wherein on and along an entire length of a rear side of the trapezoidal-shaped tubular profile comprises one or more parallel, longitudinally extending ridges.
