Vehicle restraint system

Abstract

The invention relates to a vehicle restraint system for demarcating roadways, including guard rails ( 1 ) that are detachably placed next to each other. Each guard rail ( 1 ) includes a housing-like base body ( 3 ) that can be arranged on the ground and a guide bar ( 2 ) disposed above the base body ( 3 ). Each base body ( 3 ) includes a tongue ( 9 ) at a topside ( 8 ). Each guide bar ( 2 ) at a bottom ( 7 ) has a groove ( 17 ), wherein the groove ( 17 ) during coupling engages in the tongue ( 9 ) of a base body ( 3 ), thereby creating a formfitting tongue and groove joint ( 60 ) between the guide bar ( 2 ) and base body ( 3 ).

         13 . A vehicle restraint system for demarcating roadways, comprising guard rails detachably placed next to one another, each guard rail including
 a housing-like base body for placement on a ground;   at least one guide bar arranged directly upon the base body, said base body and said guide bar engaging one another in a formfitting manner through intervention of a tongue and groove joint extending in a longitudinal direction of the base body and defined in part by a tongue formed on the base body, said guide bar having an upper web and legs which are angled in relation to the web and connected to one another by crossbeams in an area of their ends distal to the web, with the crossbeams being attached at a vertical distance to the tongue of the base body; and   at least one clamping rod for coupling the guide bar with the base body at a coupling point.   
     
     
         14 . The vehicle restraint system of  claim 13 , wherein the tongue is configured on a topside of the base body. 
     
     
         15 . The vehicle restraint system of  claim 13 , wherein the guide bar is configured as a downwardly open section. 
     
     
         16 . The vehicle restraint system of  claim 13 , wherein the guide bar is configured to define a groove forming another component of the tongue and groove joint. 
     
     
         17 . The vehicle restraint system of  claim 16 , wherein the legs of the guide bar have inwardly angled end portions in confronting relation, said groove being defined by a width which is determined by a distance between the end portions of the legs. 
     
     
         18 . The vehicle restraint system of  claim 13 , wherein the guide bar is mounted in offset relation to the base body in the longitudinal direction. 
     
     
         19 . The vehicle restraint system of  claim 13 , wherein the guard rail has two of said base body, said base bodies abutting one another in the longitudinal direction and constructed for coupling via a plug connection. 
     
     
         20 . The vehicle restraint system of  claim 13 , wherein the guard rail has two of said guide bar placed on top of one another to thereby define an upper guide bar and a lower guide bar, said upper guide bar being mountable in offset relation to the lower guide bar in the longitudinal direction. 
     
     
         21 . The vehicle restraint system of  claim 13 , wherein the guard rail has two of said guide bar, said guide bars abutting one another in the longitudinal direction and constructed for coupling via a plug connection. 
     
     
         22 . The vehicle restraint system of  claim 13 , wherein the clamping rod has upper and lower ends, said upper end being connected with the guide bar, and said lower end being braced in an abutment arranged within the base body, said base body having an upper cover plate and collision plates which are inclined to a side and connected by the cover plate, said clamping rod being guided in an area of the coupling point underneath the cover plate.
