<p>The safety barrier has a fixed part and a movable part. The safety barrier enables forming a temporary vehicle passage. The fixed part is formed from rails (2b,2c) parallel to the ground fitted to supports (1,3). The supports consist of a vertical post embedded in the ground and rail connecting pieces. The movable part is formed by a leaf constituted by movable rail segments (10,11) articulated about a vertical axis. The movable rail segments are directly connected to the fixed rail segments by vertical pivots (20,30) located behind the rail segments and separated from the support.</p> |
