Sealing or guiding strip,window frame assembly,and method of making window frame assembly

摘要

A window frame carried on the door of a vehicle is in the form of an aluminium extrusion (20) having a smooth bend (22) in the region where the top of the frame meets the corner between the "B" pillar of the vehicle and the vehicle roof. The window glass (not shown) has a sharp angle matching this corner. The aluminium extrusion (20) carries a flange (26) and is formed with a channel (24) by means of which the window sealing and guiding strip (not shown) can be secured to the frame. The sealing and guiding strip has a mitred corner matching the sharp angle of the window glass. For supporting the sealing and guiding strip in the region of this corner, a separate metal corner piece (80) is provided. This has a shoulder (86) which is a tight press fit into the channel (24) on the aluminium extrusion. It is supplied to the vehicle manufacturer already attached to the sealing and guiding strip itself, so that the strip and the corner piece (80) can be fitted to the frame in substantially a single press-fit operation. The metal piece (80) is secured to the sealing and guiding strip during the moulding operation which produces the mitre-corner in two lengths of the strip which meet at the corner.
