ABSTRACT:
A roadside energy absorbing barrier includes energy absorbing elements interposed between diaphragms, with fender panels mounted by hinges to the diaphragms. The fender panels define longitudinally extending slots, and a fastener is mounted between adjacent fender panels. This fastener includes a bolt passing through an enlarged washer, a slot in one fender panel and an adjacent fender panel. A nut is positioned on the bolt inwardly of the fender panels, and a coil spring is mounted on the bolt and reacts against the nut and the fender panels to bias the first fender panel toward the second fender panel while permitting a selected separation therebetween.
