Inertial barrier system

摘要

An inertial barrier system for attenuating the energy of errant vehicles. The system includes module means defining a frangible container having a generally inverted U-shaped configuration with an opened and enlarged upper portion and a closed lower portion. The upper and lower container portions receive a continuous mass of dispersible energy-attenuating material, and maintain the center of gravity of the mass above the lower portion of the container. This lower portion also defines a central void of substantial volume, for receiving a portion of the dispersible mass during the initial impact of the module means by an errant vehicle. Cover means are provided to close the module.
