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. |
