ABSTRACT:
The invention relates to a deformable seal element to seal the gap between the edge of an aperture in a building and the tail of a vehicle driven up to the latter, with aprons which are attached at the sides and at the top to a frame attached to the building, the frame being retained by stays invariable in height at the end near the building and reducible in length counter to the action of a return force, and the stays being constructed as horizontally aligned helicoidal springs which support at their ends remote from the building a support device for the aprons.
