Abstract: A seal assembly is provided for use in a dock leveler used to span a gap between a loading dock and a bed of a vehicle in loading or unloading position in front of the dock. The loading dock has a pit defined by opposing pit walls, a rear wall and a floor. The dock leveler has a frame mounted in the pit, a deck having front and rear portions, with the rear portion pivotally connected to the frame so that the deck can pivot up and down about a horizontal axis between a horizontal position wherein the deck is substantially co-planar with a surface of the dock, a raised, upwardly inclined position, and a lowered, downwardly inclined position. The dock leveler also has opposing deck sides which are adjacent to and move vertically relative to the pit walls.
