Vehicle passage controlling safety barrier for e.g. traffic lane, has guide rail displaced with respect to support assembly, and elastic unit that places guide rail in rest position, on support assembly, if guide rail is ejected by vehicle

摘要

The barrier has a guide rail (100) that is displaced with respect to a support assembly around an axis (102) which is transversal to a main axis (202). The guide rail extends transversal to a traffic lane to prohibit the passage of a vehicle, in a rest position. An elastic unit is constituted by springs (222, 224) and places the guide rail in the rest position, on the support assembly, if the guide rail is ejected by a vehicle.
