Abstract

A vehicular rear slider window assembly includes an upper rail and a lower rail and a fixed window panel. The rails are attached at an inner surface of the fixed window panel above and below an opening. First and second movable window panels are movable along the rails. The drive system includes a drive element at the first movable window panel, a gear element rotatably mounted at a rail of the window assembly, and first and second toothed tracks attached at the respective movable window panel and extending toward and overlapping the other movable window panel. When the drive system is operated, the drive element imparts movement of the first movable window panel along the rails. Movement of the first movable window panel causes a corresponding movement of the second movable window panel in an opposite direction along the rails via engagement of the gear element with the toothed tracks.

First claim

The invention claimed is:

1. A rear slider window assembly for a vehicle, said rear slider window assembly comprising:
an upper rail and a lower rail;
a fixed window panel comprising at least one glass panel having an inner surface and an outer surface and an opening between opposite side panel portions of said fixed window panel;
wherein said upper rail is attached at said inner surface of said fixed window panel at an upper region of said fixed window panel and above said opening;
wherein said lower rail is attached at said inner surface of said fixed window panel at a lower region of said fixed window panel and below said opening;
first and second movable window panels that are movable along said upper and lower rails, wherein said first and second movable window panels are movable between a closed position, where said first and second movable window panels cooperate to close the opening, and an opened position, where said first and second movable window panels move away from one another to open the opening;
a drive system that, when operated, moves said first and second movable window panels along said upper and lower rails between the closed position and the opened position, wherein said drive system comprises (i) a drive element that is connected to said first movable window panel, (ii) a gear element rotatably mounted at the upper rail or the lower rail of said rear slider window assembly, (iii) a first toothed track attached at said first movable window panel and extending toward and overlapping said second movable window panel, and (iv) a second toothed track attached at said second movable window panel and extending toward and overlapping said first movable window panel;
wherein said first toothed track includes (i) an attaching portion that is attached at an upper region of said first movable window panel and (ii) a toothed portion that extends from said attaching portion toward and adjacent to an upper region of said second movable window panel;
wherein said second toothed track includes (i) an attaching portion that is attached at an upper region of said second movable window panel and (ii) a toothed portion that extends from said attaching portion of said second toothed track toward and adjacent to an upper region of said first movable window panel;
wherein said gear element engages said toothed portions of both of said first and second toothed tracks; and
wherein, when said drive system is operated, said drive element imparts movement of said first movable window panel along said upper and lower rails, and wherein movement of said first movable window panel along said upper and lower rails causes rotation of said gear element via engagement of said gear element with said toothed portion of said first toothed track, and wherein movement of said first movable window panel along said upper and lower rails and rotation of said gear element causes a corresponding movement of said second movable window panel in an opposite direction opposite the movement of said first movable window panel along said upper and lower rails via engagement of said gear element with said toothed portion of said second toothed track.

2. The rear slider window assembly of claim 1 , wherein said pear element is rotatable independent of operation of said drive system to allow for manual movement of said first movable window panel and said corresponding movement of said second movable window panel.

3. The rear slider window assembly of claim 1 , wherein said gear element is disposed at a center region of said rear slider window assembly.

4. The rear slider window assembly of claim 3 , wherein one of said toothed portions is disposed above said gear element and the other of said toothed portions is disposed below said gear element.

5. The rear slider window assembly of claim 1 , wherein said drive element is routed through a guide element at a first end of said lower rail and an end of said drive element is attached at an outer end of a carrier of said first movable window panel.

6. The rear slider window assembly of claim 1 , comprising a perimeter sealing element that is attached at said fixed window panel and that circumscribes said opening, said perimeter sealing element sealing against a surface of said first and second movable window panels.

7. The rear slider window assembly of claim 6 , comprising a center sealing element attached at an inner edge of said first movable window panel that opposes an inner edge of said second movable window panel, wherein said center sealing element is configured to receive the inner edge of said second movable window panel to seal said first and second movable window panels relative to one another when said first and second movable window panels are in the closed position.

8. The rear slider window assembly of claim 7 , wherein said perimeter sealing element comprises horizontal lip seals and vertical Y-shaped seals.

9. The rear slider window assembly of claim 1 , wherein said fixed window panel comprises a single glass panel having said opening therethrough that is between said opposite side panel portions of said single glass panel.

10. The rear slider window assembly of claim 1 , wherein said fixed window panel comprises a pair of opposite side panels that are spaced apart so that said opening is between said side panels.

11. The rear slider window assembly of claim 1 , wherein applying a manual force to said first movable window panel imparts movement of said first movable window panel along said upper and lower rails, and wherein movement of said first movable window panel along said upper and lower rails causes rotation of said gear element via engagement of said gear element with said toothed portion of said first toothed track, and wherein movement of said first movable window panel along said upper and lower rails and rotation of said gear element causes the corresponding movement of said second movable window panel in the opposite direction along said upper and lower rails via engagement of said gear element with said toothed portion of said second toothed track.

12. A rear slider window assembly for a vehicle, said rear slider window assembly comprising:
an upper rail and a lower rail;
a fixed window panel comprising at least one glass panel having an inner surface and an outer surface and an opening between opposite side panel portions of said fixed window panel;
wherein said upper rail is attached at said inner surface of said fixed window panel at an upper region of said fixed window panel and above said opening;
wherein said lower rail is attached at said inner surface of said fixed window panel at a lower region of said fixed window panel and below said opening;
first and second movable window panels that are movable along said upper and lower rails, wherein said first and second movable window panels are movable between a closed position, where said first and second movable window panels cooperate to close the opening, and an opened position, where said first and second movable window panels move away from one another to open the opening;
a drive system that moves said first and second movable window panels along said upper and lower rails in tandem between the closed position and the opened position, wherein said drive system comprises (i) a gear element rotatably mounted at the upper rail or the lower rail of said rear slider window assembly, (ii) a first toothed track attached at said first movable window panel and extending toward and overlapping said second movable window panel, and (iii) a second toothed track attached at said second movable window panel and extending toward and overlapping said first movable window panel;
