AbstractA vehicle restraint employs a 4 bar linkage to lift a restraining member to a position that engages a vehicle thus restraining it at a loading dock. The linkage is upwardly biased to hold the unit in an engaging position and may be retracted by using any of a number of mechanical techniques such as hydraulic electric or pneumatic power. The actuating mechanism employs a movable sector arm with engaging lugs to co-act with the 4-bar linkage limit the degree of float of the system and form the drive transfer to initially elevate the linkage or retract it against the upward bias. The 4 bar linkage transfers all loading on the unit from the ICC to the frame thus isolating any driven members from overloads. A secondary hook mounted to the 4 bar linkage is pivotally spring loaded to limit vehicle travel away from the dock and to extend the capture range of the device in the case of ICC's bars that are damaged or mounted at non-standard positions at the rear of the vehicle.
