A retaining and sealing strip made of plastics or rubber, is supported in a channel running along the top of the window frame carried by a conventional vehicle door. The strip defines a hollow chamber running alongside the top of the window opening which, in conjunction with a lip, forms a channel in which is located the upper edge of the window glass. A wall of the chamber is pressed into sealing engagement with window glass by inflation of the hollow chamber. The upper part of the strip defines further hollow chambers, one having a relatively stiff wall hinged by a narrow neck. When this chamber is inflated, the top of the door is retained closed because any attempt at opening it results in interference between a shoulder carried by the stiff wall and a ridge formed on a relatively hard plastics or rubber retaining profile which is rivetted or stuck to the adjacent body part. When the two chambers are at least partially evacuated, the stiff wall hinges to provide clearance for opening of the door. |
