Patent ID: 7726632

Claim:
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.
