ABSTRACT:
A deformable seal of the gap between the edge of a building opening and the back end of a vehicle such as a truck or semi-trailer truck driven up to the building opening. The seal has an apron which at the sides and at the top is fastened to a rigid, downwardly opened U-shaped frame which is spaced from the building. The frame is held by inclined guides which are unchangeable in height at that end thereof facing the building. A flexible covering is provided on both sides as well as at the upper edge of the apron. One edge of this covering is fastened to the frame, and the other edge is fastened to the building. That edge of the covering facing the building is guided in such a way as to be adjustable in height. A tension spring may be provided which is effective on the guides and/or the U-shaped frame in such a manner that the edges of the covering are adjustable upwardly only counter to the effect of this tension spring.
