Abstract

L'invention concerne une glissière de sécurité pour routes comprenant un support de d'amortissement de choc disposé entre une plaque en forme d'onde et une plaque de glissière de protection, et formé d'une plaque métallique divisée en support avant et support arrière, les supports avant et arrière coopérant de manière élastique dans les sens avant et arrière. Lorsqu'un véhicule entre en collision avec une glissière de protection, les supports avant et arrière coopérant se contractent de manière souple, ce qui permet de libérer une force de choc. Dans un autre mode de réalisation de l'invention, le support d'amortissement de choc se présente sous forme d'un tube rectangulaire, une partie faible dotée d'une pluralité de trous étant formée au niveau des deux côtés. Lorsqu'un véhicule entre en collision avec une glissière de protection, la partie faible formée au niveau des côtés se contracte de manière souple, ce qui libère une force de choc.
