<p>A sealing apparatus (14) for forming a weather seal between a vehicle (V) and a loading dock (4) is provided. In some embodiments, the apparatus includes a roller seal (14) rotatably mounted to a support (22) for rotation about an axis (30). The roller seal (14) is movable in at least a vertical direction from a first position in the path of a vehicle (V) entering the parking area, to a second position wherein the roller seal (14) is disposed adjacent the top of the vehicle (V). Preferably, a curtain (60) is suspended distally of the roller seal (14) such that, when the roller seal is in the second position, the curtain (60) forms a first seal with the top of the vehicle (V) and the roller seal (14) forms a second seal with the top of the vehicle (V). The curtain (60) is semi-rigid and, in some instances, defines a ramping surface (175) to facilitate movement of the roller seal (14) over the leading edge of a vehicle (V) approaching the loading dock (4).</p> |
