A weather seal with a repositioning device

Abstract: The present invention is a weather seal (12) adapted to be secured on a flange (8) of a vehicle to seal a gap between the flange (8) and a panel member (6). The weather seal (12) includes retaining members (28) for retaining the weather seal (12) on the flange (18) and a trim lip (32) for sealing the gap between the flange (8) and panel member (16). The weather seal (12) also includes a lip repositioning device (36) for repositioning the trim lip (32) to seal the gap when the trim lip (32) is disposed in the gap.

Description: This invention relates generally to weather seals, and more particularly to a weather seal for a door on an automotive vehicle. Typically, a weather seal is used on a flange surrounding a door opening to conceal or close a gap between a panel member such as a trim panel and the flange of the door opening on an automotive vehicle. Generally, the weather seal has a U-shaped core member having an outer skin surrounding the interior and exterior of the core member. The outer skin has inwardly projecting retaining members extending within a channel defined by the core member which are adapted to grip or couple with the flange of the door opening to retain the weather seal on the flange. A trim lip or, in some cases, a sealing lip extends outwardly from one side of the exterior of the outer skin, to cover the aforementioned gap. Additionally, a tubular member may extend outwardly from the other side of the exterior of the outer skin to form a seal with the door. One disadvantage of the conventional weather seal described above is that the trim lip may become disposed in the gap between the flange and trim panel. This may occur when the weather seal is installed after the trim panel is in place on the vehicle or when the weather seal is installed on the flange and the trim panel is subsequently installed on the vehicle. As a result, additional time and money may need to be expended to remove manually the trim lip from the gap and reposition the trim lip to cover the gap and contact the trim panel. Another disadvantage is that, if the trim lip is not repositioned, an unpleasing aesthetic appearance results. GB-A-2095315 discloses an elongate weather seal adapted to be secured on a flange of a vehicle and to seal a gap between the flange and a panel member, the weather seal comprising: a U-shaped channel member having a base and two opposing side walls, for retaining the weather seal on the flange; an elastomeric trim lip extending outwardly from the channel member in a region of a side wall remote from the free end thereof, for sealing the gap between the flange and the panel member; and a trim lip repositioning member detachably secured to the trim lip for repositioning the trim lip from a position within the gap to a position across the gap with an outer edge portion of the trim lip in overlapping relationship to an adjacent edge portion of the panel member. The trim lip repositioning member is formed of the same material as the trim lip and is therefore not as strong as desired. According to the present invention, there is provided as elongate weather seal adapted to be secured on a flange of a vehicle and to seal a gap between the flange and a panel member, the weather seal comprising: a U-shaped channel member having a base and two opposing side walls, for retaining the weather seal on the flange; an elastomeric trim lip extending outwardly from the channel member in a region of a side wall remote from the free end thereof, for sealing the gap between the flange and the panel member; and a detachably secured trim lip repositioning member for repositioning the trim lip from a position within the gap to a position across the gap with an outer edge portion of the trim lip in overlapping relationship to an adjacent edge portion of the panel member; characterised in that: the trim lip repositioning member comprises a longitudinally extending reinforcement cord having an elastomeric cover member disposed thereabout, and the trim lip repositioning member is detachably disposed on the same side wall as the trim lip but nearer to the free end of the said same side wall. One advantage of the weather seal of the present invention is that the repositioning member is strong and is less likely to malfunction. For a better understanding of the present invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which:- Figure 1 is a partial side view of an automotive vehicle including a weather seal according to the present invention. Figure 2 is a sectional view taken along line 2-2 of Figure 1. Figure 3 is an enlarged perspective view of circle 3 of the weather seal of Figure 1. Figure 4 is an enlarged perspective view of circle 4 of the weather seal of Figure 1. DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Figure 1, an automotive vehicle 10 is shown with a weather seal, according to the present invention, generally illustrated at 12. The vehicle 10 includes a door opening 14 to contain a door (not shown). The vehicle 10 also includes a panel member 16 such as a trim panel disposed adjacent the door opening 14. Referring to Figures 2 and 3, the vehicle 10 includes a flange 18 peripherally extending into the door opening 14. A gap 20 is disposed between the flange 18 and the panel member 16. The weather seal 12 couples with or grips the flange 18 to close or seal the gap 20 and conceal the gap 20 from external view. The weather seal 12 includes a core member 22 formed to a generally U-shape configuration to define a channel 24. The core member 22 is made of a metallic material. The weather seal 12 also includes an outer skin 26 extruded from a polymeric material such as EPDM and surrounding the interior and exterior of the core member 22. A plurality of retaining members 28 and 30 extend from the outer skin 26 and inwardly into the channel 24. The retaining members 28 and 30 grip or couple with the flange 18 to retain the weather seal 12 onto the flange 18. A trim or sealing lip 32 extends outwardly from one side of the outer skin 26 to close or seal the gap 20 when the weather seal 12 is installed onto the flange 18. The trim lip 32 has a generally arcuate shape. Additionally, a tubular member 34 made of a sponge material may extend outwardly from the other side of the outer skin 26 to contact or sealingly engage a door. It should be appreciated that up to this point in the description the weather seal is conventional in construction. The weather seal 12 includes a lip repositioning member, generally indicated at 36, attached to the exterior of the outer skin 26 below the trim lip 32. The lip repositioning member 36 includes a generally circular reinforcement cord 38 extending longitudinally. The reinforcement cord 38 is covered or encapsulated with a cover member 40 made of a polymeric material and attached to the outer skin 26. The lip repositioning member 36 extends longitudinally beyond the end of the weather seal 12. The lip repositioning member 36 is coextruded with the outer skin 26 and is removably or detachably secured to the weather seal 12. The excess length of the lip repositioning member 36 is pulled outwardly toward the trim lip 32 to reposition the trim lip 32 such that it covers or extends over the gap 20 to contact or rest on the panel member 16. In operation, the weather seal 12 may be installed on the flange 18 either before or after the panel member 16 is secured in place on the vehicle 10. The flange 18 is disposed in the channel 24 of the weather seal 12 and the retaining members 28 and 30 grip the flange 18 to secure the weather seal 12 to the flange 18. The trim lip 32 may be disposed in the gap 20 between the flange 18 and panel member 16 as illustrated in Figure 3. If this occurs, the excess length of the lip repositioning member 36 is pulled outwardly toward the trim lip 32. As a result, the trim lip 32 is pulled outwardly and removed from the gap 20. As the lip repositioning member 36 travels longitudinally along the trim lip 32, the trim lip 32 returns to a normal position to cover or close the gap 20 and rest or contact the panel member 16 as illustrated in Figure 4. The lip repositioning member 36 may then be discarded. Accordingly, the present invention provides a simple and inexpensive device to correctly reposition the trim lip when disposed undesirably in a gap between the flange and panel member. The present invention has been described in an illustrative manner. It is to be understood that the terminology which has been used is in the nature of words of description rather than of limitation. Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described.
