Deformable sealing arrangement for the gap between the edge of an opening in a building and the back end of a vehicle that is driven up to the opening

A deformable sealing arrangement for the gap between the edge of an opening in a building and the back end of a vehicle that is driven up to the opening;

• an apron is secured to the sides and top of a U-shaped frame that is open at the bottom, is disposed at a distance from the building, and is also preferably movable in a direction toward said building, with the two side legs of said frame serving to hold the side portions of said apron, with each side portion having a given width and an upper edge, while the horizontal, top leg of said frame serves to hold the upper, transversely extending portion of said apron;
• said sealing arrangement further comprising:
• two support arms, located above the side portions of said apron and at one end thereof respectively, aid support arms being connected to each side leg of said frame in such a way as to be pivotable via a hinge joint about an axis that extends parallel to that side leg, with said upper edge of each side apron portion being connected to a respective one of said support arms in such a way that said side portions can be resiliently pressed-in in the manner of a door accompanied by the formation of a return force,
• said upper edge of each side apron portion being connected to its pertaining support arm by a respective tension spring,
• each of said support arms having a free end remote from its pertaining side leg of said frame, and
• each of said side apron portions, along said upper edge thereof, having a free upper corner remote from its pertaining side leg of said frame, with each of said tension springs being connected to said free end of one of said support arms as well as to said free upper corner of the pertaining side apron portion.
