Abstract
A sealing strip for sealing against a raisable and lowerable window glass plane such as in a motor vehicle door, comprises a triangularly shaped air-tight hollow chamber having two relatively rigid sides stiffened by a metal carrier. The third side is a relatively flexible wall. A sealing lip is pivoted on one of the rigid sides and joined by a leg to an intermediate point on the flexible wall. Partial evacuation of the chamber causes the retracted flexible wall to pull the distal tip of the lip into sealing engagement with the window glass. An increase of air pressure within the chamber causes the flexible wall to move outwards so that the force transmitted via the leg pivots the lip and moves it out of sealing engagement with the window glass.
