A vehicle door seal with a channel shaped gripping part is mounted on a bodywork flange defining the door opening and this part supports a tubular sealing part such as made of plastics or rubber of cellular or foamed configuration. The air pressure within the latter can be increased or decreased by means of an air pump connected to a tubular extension. When the door is opened, the air within the sealing part is evacuated and the sealing part collapses to permit easy closing of the door. When the door is closed, the air pressure within the tubular part is increased so as to inflate the sealing part towards its circular configuration and to bring it into sealing engagement with the closed door. The interior of the sealing part is lined with an air-impervious lining and this and the interior of the part are formed with grooves which are so configured that the collapsed sealing part has a neat appearance. |
