WINDOW SEALING AND GUIDING ARRANGEMENTS FOR VEHICLE DOORS AND WINDOWS

Technical Field

The present invention relates to window sealing and guiding arrangements, and more

particularly to a sealing or guiding strip comprising flexible material, a sealing or guiding

strip assembly including such a strip and a method of fixing a sealing or guiding strip to a

mounting flange. Embodiments of the invention, to be described in more detail below by

way of example only relate to sealing or guiding strips suitable for being carried by

vehicle doors.

Background to the Invention

It is known in the prior art, for example in WO-A-2004/050408 (WW32669WO, GDX-

7260), to provide a sealing or guiding strip formed of flexible material with a channel-

shaped recess into which a mounting flange of a door frame is inserted to fix the sealing

or guiding strip to the door in use. It is known to embed a channel-shaped relatively rigid

metal carrier within the flexible material and which extends around the channel-shaped

recess in the flexible material. This assists in fixing the sealing or guiding strip to the

mounting flange. The metal carrier is embedded within the flexible material during the

extrusion thereof. During the extrusion of the flexible material, a series of sealing lips

may be formed within the channel-shaped recess for pressing against the mounting

flange. Summary of the Invention

It is an object of the embodiment of the invention to provide an alternative to the

embedded channel-shaped carrier known from the prior art, and to avoid the complication

of embedding a rigid metal carrier in the flexible material during the extrusion thereof.

According to a first aspect of the present invention, there is provided a sealing or guiding

strip assembly including a body portion formed of flexible material having a channel-

shaped recess formed therein and a relatively rigid member having a channel-shaped part

which is positioned in the recess in use for receiving a mounting flange, the arrangement

being such that the body portion is located with respect to the mounting flange in use.

According to a second aspect of the present invention, there is provided a sealing or

guiding strip comprising flexible material and including a first recess for accommodating

a channel-shaped part of a rigid member and a second recess for receiving an attachment

part of the rigid member.

According to a third aspect of the present invention, there is provided a method of fixing

a sealing or guiding strip having a mounting recess to a mounting flange, the method

including locating a channel-shaped relatively rigid member in the mounting recess and

Detailed Description of Example Embodiments

Figure 1 shows a vehicle door 8 carrying a sealing and guiding arrangement 10 in which

a pane of window glass 12 is slidable in a vertical direction as it is raised from or lowered

into the lower part of the door 8. The sealing and guiding arrangement 10 comprises a

window frame and a sealing and guiding strip mounted on the frame. The sealing and

guiding strip comprises a first portion extending along the B-pillar of the door 8 and a

second portion extending along the roofline of the door 8. The embodiments to be

described related to the portion of the sealing and guiding strip that extends along the

roofline of the door 8. Where the two portions of the sealing and guiding strip join, a

sharp corner is formed (although this is not essential to the invention). As shown in Figure 2, along the B-pillar of the door 8, the sealing and guiding

arrangement 10 comprises a strip portion 16. The strip portion 16 is of channel form to

receive the window pane 12 and comprises an outer channel wall (on the outside of the

window pane 12) and an inner channel wall (on the inside of the window pane).

Along the top of the window frame (along the roofline and the A-pillar of the door 8), the

sealing and guiding arrangement 10 comprises a strip portion 18. The strip portion 18 is

also of channel form to receive the window pane 12 and comprises an outer channel wall

(that is, a channel wall on the outside of the window pane 12) and an inner channel wall

(that is, a channel wall on the outside of the window pane 12).

The two strip portions 16 and 18 are mitre-cut and joined together at the sharp corner 14.

The sealing and guiding arrangement 10 is produced, such as by extrusion, from flexible

material such as plastics or rubber. It is designed to provide a weather-proof seal for the

edge of the window glass 12 and also to impose low frictional movement of the glass 12.

Initially, the prior art arrangement disclosed in WO-A-2004/050408 will be described

with reference to Figure 3. Figure 3 is a cross-section on the line III-III of Figure 2. The

window frame shown generally at 50 is formed by panels 52,54 and 56 of the door, which

are joined together to form a mounting flange 58 projecting outwardly of the door. The panels 52 and 54 diverge from each other in the direction away from the flange 58 to

form a hollow space 60 and then come together to form a further flange 62 where they

are again joined together.

The strip portion 18 is extruded integrally from plastics or rubber material and defines a

channel-shaped recess 64 which embraces the flange 58 to hold the strip portion 18 in

position. The extruded material carries integral, inwardly extending lips 66 to assist in

securing the sealing and guiding strip in position on the flange 58. Further, a reinforcing

carrier 67 is embedded in the extruded material. The reinforcing carrier 67 is formed

from the rigid material, such as metal or plastics. The metal carrier 67 assists in securing

the strip portion 18 to the mounting flange 58.

Figure 4 shows a sealing strip portion in accordance with an embodiment of the

invention.

The strip portion 18A is again extruded integrally from plastics or rubber material and

defines a channel- shaped recess 64A for embracing a mounting flange (not shown in

Figure 4) to hold the strip portion 18 A in position. The extruded material of the strip portion 18A on the outside wall of the channel- shaped

recess 64A carries large flexible sealing lips 68 which, when the vehicle door 8 is closed,

seal against the bodyshell 70 (Figure 6) of the vehicle along the roofline thereof.

The material on the outside of the base 71 of the channel-shaped recess 64 carries a re¬

entrant lip 72. The extruded material of the strip portion on the inside wall of the

channel-shaped recess 64A, adjacent the mouth of the channel-shaped recess 64A, is

extended to form a limb 74 which lies against the door panel 54 (Figure 6) and terminates

in a lip (a "cosmetic lip") 76 which embraces the edge of the flange 62 (Figure 6). In

addition, the distal end of the limb 74 integrally carries the large flexible lip 78 which

extends towards the lip 72 so that, together, these lips define the channel 79 for receiving

the window pane 12 (not shown in Figure 4). A further lip 80 extends partway across the base of the channel 79.

The surfaces of the lip 72, 78 and 80 which make contact with the window pane 12 may

carry layers of flock or other suitable low-friction coating (not shown).

Extending from the opposite side of the limb 74 to the lips 78 and 80 is an integral

resiliently deformable protrusion 82 having an enlarged head portion 84. The function of

the protrusion 82 will be described later with reference to Figure 8 of the drawings. Figure 5 shows a rigid member 100. The rigid member 100 may be formed of plastics or

metal, for example. The rigid member 100 is formed from a planar sheet of material that

is bent or moulded into the configuration shown in Figure 5. The member 100 comprises

a channel-shaped part 102 sized for being accommodated in the channel-shaped recess

64A. Integrally extending from a first side of the mouth 104 of the channel 102 is a first

clamping part 106. The first clamping part 106 comprises an arm portion 108. The arm

108 is spaced apart from the first side wall 101 of the channel 102 by base part 110. The

portion of the arm 108 extending from the base part 110 extends generally parallel to the

side wall 101 of the channel 102, whereafter an intermediate part 111 of the arm 108 is

inclined towards the side wall 101 of the channel 102, and then terminates in a distal end

part 112 which is inclined in the opposite direction. The parts 111 and 112 have a hook-

shaped formation.

A second clamping part 116 extends from the second side of the mouth 104 of the

channel 102. The second clamping part 116 comprises an arm 118, an intermediate part

120, a part 121 and a distal end part 122 configured similarly to the correspondingly-

named parts of the first clamping part 106. However, a portion of the arm 118 which

extends parallel to the second side wall 103 of the channel 102 is longer than the

corresponding portion of the arm 108. The first side wall 101 of the channel 102 at predetermined positions along its length

(extending into and out of the page of the drawings) has an indentation 130 formed on the

outside surface thereof and a corresponding protrusion 132 formed on the inside thereof,

extending into the channel 102. The indentation 130/protrusion 132 may be formed, for

example, by a stamping operation.

At a corresponding position on the second side wall 103 of the channel 102 at intervals

along the length of the rigid member 100 (extending into and out of the page of the

drawings) a cut, as indicated by dotted line 134, is made in the rigid member 100, which

allows a generally rectangular tab 136 to be bent away from the second side wall 103 and inclined inwardly into the channel 102.

The strip 18A shown in Figure 4 is provided with a first recess 140 extending generally

parallel to the inside wall of the channel 64 A, and a second recess 142 extending

generally parallel to the outside wall of the channel 64 A. The recess 140 accommodates

the first clamping part 106, and the second recess 142 accommodates the second

clamping part 116, when the channel-shaped part 102 is accommodated in the channel-

shaped recess 64A. The recess 140 includes an indentation in its side wall to

accommodate the intermediate part 112 and the distal end part 111 of the first arm 108.

Similarly, the second recess 142 includes an indentation 146 to accommodate the

intermediate part 121 and distal end part 122 of the second arm 118. These parts of the arms are pressed into the indentations 144,146 when the channel-shaped part 102 is fully

accommodated in the channel-shaped recess 64A due to the resilience of the rigid

member 100.

As can be seen in Figure 4, an additional Hp 148 extends from the outside wall of the

channel 64A (from the mouth of the recess 142), across the recess 142 and the recess

64 A. This additional lip 148 is pushed away from the recesses 142,64A to allow the rigid

member 100 to be inserted into the recesses. When the additional lip 148 is released, it

returns, due to its resilience, to the position shown in Figure 4.

Figure 6 shows the outer panel 56A and inner panel 54 of the door 8, and also the part 70

of the body shell of the vehicle of which the door 8 forms a part, along the roofline

thereof. Where the panels 54 and 56A are joined together at a first end thereof, they form

a flange 58A. The panels 54 and 56A diverge from each other in a direction away from

the flange 58A to form a hollow space 60 and then come together again to form a further

flange 62.

Figure 7 shows an enlarged view of the flange 58 A. In accordance with the embodiment,

at predetermined positions along the length of the panel 56A (extending into and out of

the page of the drawings) a part of the panel 56A is cut away and removed. This creates a recess 160 in the flange 58, the base of the recess 160 being formed by the inner panel

54. The cut-away portion of the panel 56A may be rectangular, for example.

Further, the panel 54 has an aperture 162 formed therein, providing an opening into the

hollow space 60.

The assembly shown in Figure 8 is formed by mounting the rigid member 100 to the

sealing strip 18 A, as a first step. The channel-shaped part 102 of the rigid member 100 is

fully accommodated in the channel-shaped recess 64 A of the strip 18. The first and

second clamping parts 106, 116 are likewise fully accommodated in the first and second

recesses 140,142 of the strip 18A. As explained above, the configuration of the clamping

parts 106,116 and the indentations 144,146 in the recesses 140,142, together with the

resilience of the rigid member 100, serve to fix the rigid member 100 in position with

respect to the strip 18.

As a second step, the assembled rigid member 100 and strip 18A are mounted onto the

door frame. The flange 58 passes into the channel-shaped part 102 of the rigid member

100 (the additional Hp 148 being temporarily bent away from the recesses 64A,142 to

facilitate this). As the flange 58 passes into the channel-shaped part 102 of the rigid

member 100, the resiliently deformable protrusion 82 of the strip 18 is pushed through

the aperture 162 in the panel 54 and into the hollow space 60. After passing through the aperture 162, the enlarged head 84 resiles and presses against the panel 54 around the

edges of the aperture 162.

Also, during insertion of the flange 58 into the channel-shaped part 102 of the rigid

member 100, the tab 136 is resiliently deformed to lie generally parallel with the second

side wall 103 of the channel-shaped part 102 of the rigid member 100 and/or the second

side wall 103 is resiliently flexed away from the first side wall 101 as the panel 56 A

presses against the tab 136. When the tab 136 comes into alignment with the recess 160

formed in the flange 58, this resilient deformation of the tab 136 and/or the side wall 103

ceases and the tab engages against the parts of the panels 56A,54 forming the recess 160.

Also, the protrusion 132 presses against the panel 54 of the flange 58 A. The pressure

applied by the protrusion 132 and the cooperation of the tab 136/recess 160 serve to

prevent or reduce relative movement between the rigid member 100 and the door frame.

The resiliently deformable protrusion 82 of the strip 18 and the aperture 162 in the panel

54 serve to reduce or prevent relative movement between the strip 18 A of the strip 18 and

the door frame.

Figure 9 shows a second embodiment of the invention, which is generally similar to the

first embodiment. However, the part of the strip 18B which overlies the base 71 of the

channel-shaped recess 64A, and which is visible from the exterior of the vehicle of which

the door 8 forms a part, has a generally C-shaped recess formed therein, in which a generally C-shaped trim piece 170 is accommodated. The trim piece 170 comprises an

arcuate main portion 172 from which inwardly tapering legs 174 and 176 integrally

extend. The configuration of the legs 174,176 secures the trim piece 170 in position

against the resilience of the material of the strip 18B. The trim piece 170 may be formed

of coloured plastics or metal. The trim piece 70 may have a gloss or chrome-effect finish

to enhance the appearance of the door frame.

In the embodiments, the invention has been described in relation to a glass run extending

along the part of a door frame running along the roof line of a vehicle. However, the

invention is applicable to sealing arrangements in general, and not to any particular vehicle component or part thereof.
