ABSTRACT:
A bottom wiper seal for a moving glass, in particular in a car door, the wiper seal comprising a stub or clamp for fixing and mounting on the frame of the door and a first sealing lip carried by the stub and suitable for co-operating with the window glass. The wiper seal further comprises a second lip which is offset downwards relative to the first, and which is shaped and placed in such a manner as to come into contact with the window glass only when the glass is fully extended, in which case the second lip bears sufficiently against the glass for the lip to provide satisfactory sealing, with the first lip being covered on portions thereof liable to come into contact with the window by means of a relatively flexible covering of flock, whereas the second lip is coated on its operative portion with a sliding coating.
