Window sealing and guiding arrangements

Abstract

A window frame arrangement, such as for a window opening carried by a vehicle door, is described for use where a stiff window frame is provided with a smoothly radiussed region across a change in direction, such as a corner (14), of the opening. Two separate sealing and guiding strips made of flexible material, each defining a window-glass receiving channel, have respective mitre-cut ends joined together to form a sharp angle at the corner (14) which is outside the smoothly radiussed region of the frame there. One of the sealing and guiding strips comprises extruded material defining a channel (64) which embracingly grips a flange (58) forming part of the window frame. The flexible material defines a small lip (72) positioned for contacting the outside of the window glass (12), and is extended to provide a limb (74) carrying a larger lip (78) for contacting the inside surface of the window glass (12). This limb (74) lies alongside a panel part (54) which is part of the window frame and is secured thereto by an integral projection (82). The flexible material defines a hollow chamber (90) at the end of the limb (74). In the smoothly radiussed region of the window frame, the window frame panel (54) has a correspondingly greater and progressively varying length than elsewhere, and over this region the flexible material is cut through at the wall of the hollow chamber (90) and a separate edge formation part (100) is moulded onto the strip (and also onto the second strip meeting it at the sharp corner), and carries a cosmetic lip (102) which extends over a flange (62) at the edge of the panel (54). Along the remainder of the strip, outside the smoothly radiussed region, the flexible material adjacent the hollow chamber (90) defines an integral cosmetic lip.
