Abstract:
A vehicle restraint adapted to be mounted adjacent a face of a loading dock for selectively restraining the ICC bar of a vehicle parked adjacent the dock face, the restraint comprising:a restraining member adapted for movement relative to the dock face to a position wherein the restraining member restrainingly engages the ICC bar, the restraining member including a shank portion and a barrier portion operatively coupled to the shank portion,a sensor member operatively coupled to the restraining member and movable to a sensing position in response to the restraining member moving to a restraining position,a lock mechanism for selectively preventing at least downward movement of the restraining member away from a restraining position, the lock mechanism being responsive to movement of the sensor member away from the sensing position to lock the restraining member against at least downward movement, and responsive to movement of the sensor member to the sensing position for unlocking the restraining member from at least downward movement,whereby the restraining member is prevented from at least downward movement when relative vertical motion between the ICC bar and the restraining member allows the sensor member to move away from the sensing position.
