ABSTRACT An inflatable dock seal for mounting about a loading dock opening to provide a cushioned seal against a vehicle has an upper hollow inflatable curtain and a pair of vertical inflatable side members; the side members inflate laterally of the opening directly towards each other along a phantom axis of inflation which is perpendicular to a phantom axis of entry of the opening; the upper hollow inflatable member is located in opposed spaced apart relationship with a rear end of a support structure, and the pair of vertical hollow inflatable members is located in opposed spaced apart relationship with the rear end of the support structure, the vertical inflatable members are in facing spaced apart relationship and are inflatable directly towards each other, laterally of the opening along a phantom axial line of inflation generally perpendicular to the phantom axis of entry, the facing spaced apart relationship of the vertical inflatable members is maintained throughout inflation along the phantom axial line of inflation, and the opposed spaced apart relationship of the inflatable seal and the rear end of the support structure is maintained throughout inflation of the inflatable seal, an air vent in the inflatable seal permits constant exit of air under pressure from the inflatable seal, whereby the inflatable seal is yieldable.
