Abstract
A deformable sealing arrangement for the gap between the edge of an opening in a building and the back end of a vehicle that is driven up to the opening. An apron is provided, with the side portions thereof being secured to the side legs of the U-shaped frame, and with the upper, transversely extending portion of the apron being secured to the horizontal leg of the frame. A horizontal tensioning member is provided below the horizontal, top leg of the frame, with the ends of this tensioning member being secured to the upper ends of the side legs of the frame. By tightening the tensioning member, the top leg can buckle upwardly. This counteracts the formation of creases in the apron and also counteracts a lateral displacement of the side legs.
