Abstract

Vehicle restraints with activated catches are disclosed. An example vehicle restraint includes a main body mountable at a loading dock and to move vertically relative to the loading dock. A barrier is movable relative to the main body to selectively block and release a RIG of a vehicle, where the barrier is selectively movable to a first blocking position to block the RIG, a stored position to release the RIG, and an intermediate position between the first blocking position and the stored position. A pawl is movable relative to the barrier between an activated position and a released position. A stop is carried by the main body and a pawl actuator is coupled to at least one of the main body and the barrier. The pawl actuator has a contact surface to engage the RIG, where the contact surface is movable between a raised position and a lowered position relative to the barrier. The contact surface moves between the raised position and the lowered position in response to relative movement between the RIG and the barrier while the contact surface is in engagement with the RIG. Movement of the contact surface from the raised position to the lowered position is to cause the pawl to move fr…
