Abstract
A sealing and wiping arrangement is shown for mounting along the waist-line gap of a vehicle door through which gap a window glass is raised and lowered. The sealing and wiping arrangement is made of plastics or rubber material and grippingly engages a flange on the outside part of the vehicle door. A sealing lip is formed by part of the outside wall of a first flexible chamber. A wiper blade is mounted on the outside of the flexible wall of a second flexible chamber separate from the first chamber. When the glass is stationary, the first chamber is in an expanded state to ensure that the sealing lip is in firm sealing contact with the surface of the window glass. At the same time, the second chamber is in an expanded state and ensures that the wiper blade is clear of the window glass. When the window glass starts to move, the first chamber is partially evacuated so that the sealing lip is moved clear of the surface of the glass and does not impede glass movement. When the glass stops, the first chamber is re-expanded by increasing its internal pressure. When wiping of the glass surface is to take place, the second chamber is partially evacuated, and this causes the wiper blade to be pivotted into wiping contact with the glass surface.
