摘要
Procedure for improving the energy absorption of an impact against a safety barrier (11) for the road, which comprises a fence (14, 15, 19, 21) equipped with at least two parallel horizontal railings (141, 142 , 151, 152, 191, 192, 213, 214, 215, 216, 217), supports (11) and fastening means (12, 17, 23-25) of the fence (14, 15, 19, 21) a the supports (11), characterized in that it consists of absorbing at least part of the energy of an impact, causing the fence (14, 15, 19, 21) to swing from a position called "resting", where minus two railings (141, 142, 151, 152, 191, 192, 213, 214, 215, 216, 217) are displaced in relation to a vertical plane (V) and a horizontal plane, towards a position called "operating" , in which at least two railings (141-142, 151-152, 191-192, 213-214, 213-214-215) tend to line up vertically.
