ABSTRACT:
An inflatable seal for sealing the open area between the perimeter of an opening in a wall of a building and the body of a vehicle received in the opening. The seal comprises an inflatable member which is mounted on the wall in the opening and a blower assembly for inflating the inflatable member and for maintaining it in an inflated or expanded disposition wherein it extends inwardly into the opening for sealingly engaging the sides of the vehicle body. The seal further comprises an inner partition in the inflatable member for reducing outward bulging of the walls thereof to thereby maintain the inflatable member in substantially inwardly extending relation in the opening and recoil members are provided for retracting the inflatable member to a position wherein it is adjacent the perimeter of the opening when the blower assembly is deenergized. The seal can compensate for minor misalignments of the vehicle in the opening and provides an effective weatherproof seal around the vehicle body so that repair work or the like can be effected on the portions of the vehicle inside the building.
