Abstract (en)
A variable geometry road barrier comprising a plurality of supports joined with at least one longitudinal beam (160), wherein at least one support comprises a base (101, 201), a substantially vertical tiltable post (110, 210) connected at its lower portion (111, 211) with the base (101, 201), a substantially horizontal toothed bar (120, 220) attached to the base (101, 201) and extending substantially perpendicularly to the longitudinal beam (160), at least one arm (150, 155, 250, 255) connected pivotably at its first end (151, 251) to an upper portion (112, 212) of the post (110, 210), and at its second end (152, 252) to an energy absorber, the energy absorber comprising at least one rotor (131, 132, 231) coupled with a toothed wheel (133, 233) mounted rotatably on a shaft (134, 234) to which the second end of the arm (150, 155, 250, 255) is connected, the toothed wheel (133, 233) being meshed with the toothed bar (120, 220) such that the displacement of the upper portion (112, 212) of the post (110, 210) induces rotation of the rotor (131, 132, 231).
