Abstract
A barrier for a loading dock having an opening in a wall having a dock leveler positioned in a floor of the loading dock adjacent said opening. The dock leveler has a horizontal position where traffic may cross to adjacent areas of the loading dock. A support is located along a side of the dock leveler. A deformable barrier arm is pivotedly connected to the support by a mounting for movement between a horizontal blocking position and a raised vertical position exposing the opening. The mounting has a pivotal connection to the support to permit the deformable barrier arm to move in a vertical arc for raising and lowering the arm and a loose connection to the barrier arm to permit relative motion between the barrier arm and the mounting upon the application of a horizontal load to the barrier arm.
