Abstract:
1. A guardrail terminal comprising: a plurality of vertical supporting members fixed to the ground one after the other along the edge of a road; a first transverse horizontal retaining member fixed to the vertical supporting members at a height off the ground, and positioned in a horizontal plane so as to extend gradually away from the edge of the road, with the first transverse horizontal retaining member having a first end closer to the edge of the road than a terminal second end; and a second transverse horizontal retaining member which projects from the second end, curves back in the horizontal plane towards said first transverse horizontal retaining member, and is fixed by a terminal end to said first transverse horizontal retaining member, so as to define, together with the first transverse horizontal retaining member, a substantially tear-shaped collapsible annular member, wherein the second transverse horizontal retaining member further comprise an initial portion fixed to the terminal second end of said first transverse horizontal retaining member, and bent substantially into an L in the horizontal plane, so as to have, centrally, a given constant radius of curvature (r an intermediate portion bent substantially into a V in the horizontal plane, so as to have, centrally, a given constant radius of curvature (r an appropriately shaped end portion, the end of which is fixed directly to said first transverse horizontal retaining member.
