Abstract
A vehicle restraint for securing a truck to a loading dock. The restraint is actuated by a vehicle ICC bar which moves an arm of the restraint. By use of a cam follower and spring system a restraint member is raised using the motion of the arm to transfer energy to raise the restraint. In the upright position, the restraint captures and prevents a truck from backing away from the dock. The system is held and biased into the engaging position and is released by a mechanical trapping mechanism.
