Sealing strips

Claim 2

A sealing strip for a movable pane of window glass, comprising flexible material defining a channel for receiving the window glass, the flexible material forming the wall on one side of the channel bearing against the window glass and being relatively thin compared with the thickness of the window glass and having embedded therein a strip of metal which is wholly generally planar and of sufficient gauge to act as a reinforcement for the wall, the wall and the embedded strip overlapping the edge of the glass in the channel.

Claim 3

A sealing strip according to claim 1, in which the said metal strip comprises a longitudinally extending strip having parallel slits extending partly across its width.

Claim 4

A strip according to claim 1, comprising a frame for the window and defining a flange, and in which the flexible material defines a further channel for closely embracing the flange.

Claim 5

A sealing strip according to claim 3, in which the window frame defines a channel spaced from the said flange and in which the flexible material has an extended part which is spaced from the further channel of the flexible material and is locked within the channel defined in the window frame.

Claim 6

A sealing strip according to claim 3, including a further metal strip embedded within the flexible material for reinforcing it and which is separate from and spaced from the first-mentioned metal strip.

Claim 7

A sealing strip according to claim 5, in which the further metal strip includes a channel-shaped part which embraces the further channel in the flexible material.

Claim 8

A sealing strip according to claim 1, in which the flexible material is integral with a sealing part for sealingly bearing against a part surrounding the window opening.

Claim 9

A sealing strip according to claim 1, including a separate part made of flexible material and which is supported so as to bear sealingly against the face of the window pane opposite to the face against which the said wall bears.

Claim 10

A sealing strip according to claim 8, including a frame for the window and defining a flange, and in which the separate part is attached to a further flange of the window frame but spaced from the first-mentioned flange.

Claim 11

A sealing strip according to claim 9, in which the separate part incorporates metal reinforcement.

Claim 12

A sealing strip according to claim 1, in which the metal strip is omitted from part only of the length of the said wall.

Claim 13

A sealing arrangement for sealing a movable pane of window glass forming part of a vehicle door, comprising a metal frame attached to the door and defining the window opening and being in the form of a metal channel having the mouth of the channel facing outwardly of the vehicle with the distal part of the side wall of the channel on the peripherally outermost part of the frame defining a first flange extending outwardly of the vehicle and substantially normally to the plane of the window opening and with the distal part of the other side wall of the channel being bent to form a second flange extending substantially parallel to the plane of the opening and towards the centre of the opening, a sealing strip having first and second separate parts made of extruded plastics or rubber material, the first sealing strip part having a lip positioned on the outside of the vehicle and forming one side wall of a first, window pane receiving, channel running around at least part of the periphery of the window opening and also defining a second channel facing at right angles to the first channel and sized so as closely to embrace the first flange and thereby to support the first part of the sealing strip on the frame, the second sealing strip part being made of extruded plastics or rubber material and defining a third channel which closely embraces the second flange and supports a flexible sealing lip bearing against the inside face of the window glass, the lip of the first sealing strip part incorporating a generally planar metal reinforcement which is thin compared with the thickness of the pane of window glass and overlaps the edge of the window glass.

Claim 14

A sealing arrangement for sealing a movable pane of window glass forming part of a vehicle door, comprising a metal frame attached to the door and defining the window opening and being in the form of a metal channel having the mouth of the channel facing outwardly of the vehicle with the distal part of the side wall of the channel on the peripherally outermost part of the frame defining a first flange extending outwardly of the vehicle and substantially normally to the plane of the window opening and with the distal part of the other side wall of the channel being bent to form a second flange extending substantially parallel to the plane of the opening and towards the centre of the opening, a sealing strip having first and second separate parts made of extruded plastics or rubber material, the first sealing strip part having a lip positioned on the outside of the vehicle and forming one side wall of a first, window pane receiving, channel running around at least part of the periphery of the window opening and also defining a second channel facing at right angles to the first channel and sized so as closely to embrace the first flange and thereby to support the first part of the sealing strip on the frame, the second sealing strip part being made of extruded plastics or rubber material and defining a third channel which closely embraces the second flange and supports a flexible sealing lip bearing against the inside face of the window glass, the lip of the first sealing strip part incorporating a generally planar metal reinforcement which is thin compared with the thickness of the pane of window glass and overlaps the edge of the window glass.

Claim 15

A sealing arrangement according to claim 12, in which the frame includes a further metal channel secured within the first-mentioned metal channel, the further metal channel lockingly engaging an extension of the plastics or rubber material of the first sealing strip part.

Claim 16

A sealing arrangement according to claim 12, in which the metal reinforcement of the lip of the first sealing strip part is in the form of a longitudinally extending metal strip having a plurality of substantially parallel slits extending partway across its width.

Claim 17

A sealing arrangement according to claim 12, including a further metal reinforcement embedded in the plastics or rubber material of the first sealing strip part, this further metal reinforcement being separate from and spaced from the first-mentioned metal reinforcement and including a channel-shaped region which embraces the second channel therein.
