Abstract
A 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 based 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 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.
