Gundrail installation designs are described that incorporate a box beam rail as the structral rail member. The box beam rail member (62) may have an open cross-section or a closed cross-section. An impact head (102) is provided to bend and deflect the rail member during an en-on collision, allowing the rail member to be deflected away from the roadway and out of the path of an end-on impacting vehicle. The impact head includes a striking face (18) and a chute (104) portion that receives the box beam rail member therewithin. In addition to bending and deflecting the rail member, the impact head may also include a flattening (112, 124) section for flattening the rail member.

L'invention concerne des conceptions d'installations de glissières de sécurité comprenant un élément de rail en caisson comme élément de glissière structurel. Ledit élément de rail en caisson (62) possède une section transversale ouverte ou une section transversale fermée. Une tête d'impact (102) permet de plier et de dévier l'élément de rail au cours d'une collision, ce qui permet d'écarter ledit élément de rail de la chaussée et du chemin du véhicule entré en collision. Ladite tête d'impact comprend une face de choc (18) et une partie de chute (104) recevant l'élément de rail en caisson. Outre, le pliage et la déviation de l'élément de rail, la tête d'impact peut également comprendre une section d'aplatissement (112, 124) destinée à aplatir ledit élément de rail.
