Abstract (en)
The road safety device (1) comprises a plurality of uprights (2) ordered in longitudinal rows (21) which extend in the direction of the longitudinal axis (L) of the device (1) from the front side (3) to the rear side (4) of the device (1), and in transverse rows (2t) which extend from one lateral side (5) to the other (6) of the device (1) transversely with respect to the direction of the longitudinal axis (L) of the device (1), a plurality of collapsible primary profiles (7) forming a rigid interconnection between the adjacent uprights (2) of the longitudinal rows (21), a fixed and undeformable rear stop (8) to which the rear transverse row (2t) of uprights (2) is rigidly connected, and means for supporting and guiding the sliding of the uprights (2) in the direction of the longitudinal axis (L) of the device (1), the primary profiles (7) being collapsible in succession as a result of opposition of said rear stop (8) following frontal impacts against the front side (3) of the device (1) in such a way as to progressively absorb the kinetic energy released by the frontal impacts.
