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.
Barrière routière absorbant l'énergie. La barrière est constituée d'éléments absorbant l'énergie placés entre les entretoises, des panneaux absorbant l'impact d'un pare-chocs étant fixés aux entretoises au moyen de charnières. Les panneaux absorbant l'impact d'un pare-chocs présentent des fentes longitudinales, et un dispositif de fixation relie les panneaux adjacents. Ce dispositif de fixation comprend un boulon qui traverse une rondelle élargie, une fente réalisée dans le panneau et le panneau adjacent. Un écrou est vissé au boulon à l'intérieur du panneau, et un ressort hélicoïdal est fixé au boulon et presse contre l'écrou et les panneaux de manière à incliner le premier panneau vers le deuxième tout en maintenant l'espace prévu entre les panneaux.
