ABSTRACT:
A sealing arrangement is shown for providing enhanced sealing for the edge of a window pane for the window opening in the upper part of the door of a vehicle body. In the case where the door carries no frame for the window, the sealing arrangement is carried by the frame of the door opening. The sealing arrangement comprises longitudinally extending lips defining a shallow groove between them, and in the base of which groove are formed apertures. When the window pane is in the closed position, suction is applied to the groove through holes in its base, and ensures that the lips are in enhanced sealing and supporting contact with the periphery of the window glass. The lips and the groove are formed in an outside wall of a chamber to which pressure can be applied so as to force the lips towards the window pane. The pressure in the chamber and the suction in the chamber can be controlled in synchronism with the raising and lowering of the window pane and with the opening and closing of the door.
