<p>The invention relates to a dock seal which includes at least one inflatable sealing element which functions to press sealingly against a loading/off-loading vehicle located in the immediate vicinity of a loading port, and which further includes means for returning the inflated sealing elements to a rest state. The invention is characterized in that at least one sealing element is provided with an outer casing which, when the element is in an inflated state, essentially surrounds and at least partially abuts the largest outer surface of the sealing element and extends around the major part of its perimeter, and wherein the casing forms at least a part of the element returning means. When the element has been returned to its non-use position, the casing also functions to squeeze the element to a fixed rest position and therewith also protect the element against the influence of external forces. <IMAGE></p> |
