Abstract

A slider window assembly for a vehicle includes at least one fixed window panel and a movable window panel that is movable along an upper rail and a lower rail at the at least one fixed window panel between a closed position and an opened position. The upper rail includes a channel, and a filler is disposed in the channel of the upper rail. The filler includes a filler body having opposite side walls, and the filler includes lips established along respective ones of the side walls. The lips are extruded onto and along the filler body. The lips include a compressible and flexible material and provide a dampening and cushioning function at the movable window panel when the movable window panel is disposed in the channel of the upper rail.

First claim

The invention claimed is:

1. A slider window assembly for a vehicle, said slider window assembly comprising:
at least one fixed window panel, said at least one fixed window panel defining an opening;
an upper rail and a lower rail attached at said at least one fixed window panel;
wherein said upper rail comprises a channel;
a filler disposed in the channel of said upper rail;
wherein said filler comprises a filler body having opposite first and second side walls along a filler channel, and wherein said filler comprises first and second lips established along the respective first and second side walls of said filler body;
wherein said first and second lips are extruded onto and along said filler body;
wherein said first lip is affixed along said first side wall of said filler body and said second lip is affixed along said second side wall of said filler body, and wherein said first and second lips are separate and distinct from one another and spaced apart from one another;
a movable window panel that is movable along said upper rail and said lower rail, with an upper region of said movable window panel received in the filler channel of said filler in the channel of said upper rail;
wherein said movable window panel is movable between a closed position, where said movable window panel is disposed at said opening, and an opened position, where said movable window panel is disposed at least partially along said at least one fixed window panel;
wherein each of said first and second lips of said filler comprises a compressible and flexible material and provides a dampening and cushioning function at said movable window panel when the upper region of said movable window panel is received in the filler channel of said filler in the channel of said upper rail; and
wherein said filler body comprises a material different than the compressible and flexible material of said first and second lips of said filler.

2. The slider window assembly of claim 1 , wherein said filler body comprises a plastic material.

3. The slider window assembly of claim 2 , wherein said first and second lips comprise a pliable rubber material.

4. The slider window assembly of claim 3 , wherein said first and second lips comprise EPDM or TPE material.

5. The slider window assembly of claim 1 , wherein said first lip comprises a flexible lip that extends from said first side wall of said filler body.

6. The slider window assembly of claim 5 , wherein said second lip comprises a compressible layer of material at and along said second side wall of said filler body.

7. The slider window assembly of claim 6 , wherein said first and second lips are disposed at the respective first and second side walls so as to protrude into the filler channel and into contact with opposite sides of said movable window panel.

8. The slider window assembly of claim 1 , wherein said first and second lips are co-extruded onto and along said filler body.

9. The slider window assembly of claim 1 , wherein said filler body and said first and second lips are formed via a two-shot extrusion process.

10. The slider window assembly of claim 1 , wherein said filler body and said first and second lips are formed via a three-shot extrusion process.

11. The slider window assembly of claim 1 , wherein said at least one fixed window panel comprises a single fixed window panel having an opening therethrough.

12. The slider window assembly of claim 1 , wherein said at least one fixed window panel comprises first and second fixed window panels defining an opening therebetween.
