3 Claims. (Cl. 25E-13.1)

This invention relates to guard rails of the type using flat metal strips. In this type the strips are generally mounted in offset relationship from the posts by means of elastic members and sometimes cause trouble in that a colliding vehicle is thrown into the path of oncoming trailic by the rebound caused by the elasticity of these members. One of the objects of the present inventors is to diminish or eliminate this rebounding action.

vehicle, the strip 4 has backwardly angling edge portions 4a and is fixed to the bracket 2 by bolts 5 which pass through these portions and are therefore out oi the plane of the face of the strip. It follows that a vehicle sliding along the strip will not be torn by these bolts.

We claim:
