Abstract:
A guard rail construction for use at an outer edge of a road, the guard rail construction comprising:a guard member, the guard member defining a collision point; a support element attached to the guard member, the support element being supportable on a substrate such that the support element is pivotable in a rearward direction relative to the outer edge of the road from an upright position about a pivot point to such an extent that the support element is supported on the substrate at a support point, wherein the support point is arranged in a higher position relative to the substrate than the pivot point when the support element is in the upright position and an angle between a line through the pivot point and the collision point and a line through the pivot point and the support point is greater than 90Â°, the pivot point being formed through the deformation of a weakening in the support element; and a deformable element provided on the support element for at least partially absorbing collision energy, the deformable element being disposed behind or in a vertical plane which extends through the pivot point perpendicular to the substrate.
