ABSTRACT:
An energy absorbing roadside crash barrier includes a scissors linkage having first and second ends. The scissors linkage is movable between an extended position and a collapsed position. A mounting element is coupled to the first end of the scissors linkage to mount the scissors linkage to a roadside obstacle. Deformable energy absorbing elements are mounted to the scissors linkage and positioned such that movement of the scissors linkage from the extended to the collapsed positions deforms the energy absorbing elements, and the energy absorbing elements thereby progressively resist collapse of the scissors linkage. A tension member is secured to the scissors linkage to apply a restraining force to hold the scissors linkage in the extended position, until forces tending to collapse the linkage exceed a pre-set range of values.
