Filed:

May 23, 1985

Appl. No.:

6/737273

Inventors:

John Carne - Nashville TN

Assignee:

State of Connecticut - Hartford CT

International Classification:

E01F 1500

US Classification:

404 6

Abstract:

A stationary impact attenuation system (10) for reducing the severity of vehicular collisions occasioned by an errant vehicle striking an immovable object. The subject stationary impact attenuation system (10) includes support means (14), impact attenuating means (12) and protective means (16). The support means (14) is located in juxtaposed relation to an immovable object and so as to lie between the immovable object and an oncoming errant vehicle. The impact attenuating means (12) is positioned in supported relation on the support means (14) and is selectively operative to entrap an errant vehicle striking the stationary impact attenuation system (10) at a first location and to redirect an errant vehicle striking the stationary impact attenuation system (10) at a second location. The protective means (16) is positioned in juxtaposed relation to the impact attenuating means (12) and is operative to prevent the buildup of snow and ice on the other components that comprise the stationary impact attenuation system (10).

Abstract:

A narrow stationary impact attenuation system (10) for reducing the severity of vehicular collisions occasioned by an errant vehicle striking an immovable object at narrow hazard sites. The subject narrow stationary impact attenuation system (10) includes crash cushion means (12), lateral stability means (14), backup means (16), support means (18), lateral deflection means (20), vehicle anti-vaulting means (22), redirection means (24), and base means (26). The lateral stability means (14) extends the length of the crash cushion means (12) on either side thereof. The backup means (16) is positioned in juxtaposed relation to the crash cushion means (12) at the rear thereof. The support means (18) is positioned in juxtaposed relation to the crash cushion means (12) at the front thereof. The lateral deflection means (20), the vehicle anti-vaulting means (22) and the redirection means (24) are each mounted in supported relation at selected positions relative to the crash cushion means (12). The base means (26) provides the pavement support for all of the components that collectively comprise the subject narrow stationary impact attenuation system.
