ENERGY ABSORBING BARRIER POST ASSEMBLY

摘要

A barrier post which is angularly movable at a predetermined angle from vertical upon impact at any angle, the point of the angular movement is damped by movement of a viscous material past a piston within a cylinder. The exterior surface of the post is formed to frictionally restrain the impacting object against upper sliding movement along the post. A group of such posts are to be employed to effect complete absorption of the impact force.
