Abstract:
1. An impact slider assembly for use with a guardrail system having at least one support post, a first rail, and a second rail, said assembly comprising: an impact slider bracket configured for attachment to the second rail; an impact slider panel movable independently of the at least one support post, wherein the impact slider panel is configured for attachment to the first rail and substantially surrounding the first rail, the second rail, and said impact slider bracket, and wherein the first rail passes through an opening in said impact slider panel to a first side of said impact slider panel and said second rail passes through said impact slider panel to an opposite second side of said impact slider panel, such that the first and second rails overlap, wherein the impact slider panel gathers and retains the first and second rails during a substantially longitudinally directed impact that causes telescoping of the first and second rails at said impact slider panel and a stop fastened to the impact slider bracket, wherein the stop abuts against and is larger than the opening at the second side of the impact slider panel thereby preventing said stop from passing through said impact slider panel as a result of longitudinal pulling caused by a side impact and thus preventing the overlap between the first and second rails from separating.
