Flush-mounted vehicle restraints

A vehicle restraint installed within a pit underneath a dock leveler of a loading dock platform includes a single actuator that both extends and raises a barrier into engagement with a vehicle's ICC bar. When the barrier is in a retracted, stored position, the barrier is underneath the dock leveler and behind a front face of the loading dock platform. To engage the vehicle's ICC bar, the single actuator extends to first push the barrier along a first track to an intermediate position. That same actuator then pushes the barrier along a second track to a raised, operative position where the barrier engages and captures the vehicle's ICC bar. A spring coupled to the actuator provides the barrier with freedom to float along the second track to accommodate similar incidental movement of the ICC bar as the vehicle is serviced at the dock.
