Abstract

A rear slider window assembly for a vehicle includes a frame portion having an upper rail and a lower rail, a fixed window panel that is fixed relative to the frame portion, and a movable window panel that is movable along the upper and lower rails. The movable window panel has a first electrical element established at a surface thereof. The first electrical element is in electrical connection with a vehicle power source via a flexible cable having one end electrically connected to the first electrical element at the movable window panel and another end electrically connected to a second electrical connector at the fixed window panel. The flexible cable flexes in response to movement of the movable window panel relative to the fixed window panel. A wire guide is disposed at the fixed window panel and the flexible cable is routed along the wire guide.

Claims

1. A rear slider window assembly for a vehicle, said rear slider window assembly comprising:

a frame portion having an upper rail and a lower rail;

a fixed window panel that is fixed relative to said frame portion;

a movable window panel that is movable along said upper and lower rails, wherein said movable window panel is movable between a closed position and an opened position;

wherein said movable window panel has a first electrical element established at a surface of said movable window panel;

wherein said first electrical element is in electrical connection with a power source of the vehicle and remains in electrical connection with the power source of the vehicle irrespective of whether said movable window panel is in said opened position or said closed position;

wherein said first electrical element is in electrical connection with the power source of the vehicle via a flexible cable that has one end secured to and electrically connected to a first electrical connector at said first electrical element at said movable window panel, and wherein another end of said flexible cable is secured to and electrically connected to a second electrical connector at said fixed window panel;

wherein said flexible cable flexes in response to movement of said movable window panel relative to said fixed window panel;

wherein said flexible cable comprises conductive wires disposed in and along an overmolded serrated polymeric wire sheath; and

wherein said flexible cable is flexible in a flexing direction while being substantially non-flexible in a non-flexing direction, said non-flexing direction being generally transverse to said flexing direction; and

wherein said serrated polymeric wire sheath has serrations along one side region of said serrated polymeric wire sheath so as to be flexible in said flexing direction while being substantially non-flexible in said non-flexing direction.

2. The rear slider window assembly of claim 1, wherein said first electrical element comprises a first heater grid established on said movable window panel, and wherein a second heater grid is established on said fixed window panel.

3. The rear slider window assembly of claim 2, wherein said first and second heater grids comprise a plurality of electrically conductive traces disposed at said respective window panels.

4. The rear slider window assembly of claim 1, wherein said fixed window panel comprises a first fixed window panel and wherein said rear slider window assembly comprises a second fixed window panel with an opening between said first and second fixed window panels, and wherein said movable window panel is movable between said closed position and said opened position relative to said opening, and wherein each of said fixed window panels has an electrical element established at a surface of the respective fixed window panel.

5. The rear slider window assembly of claim 1, wherein said fixed window panel comprises a single panel with an aperture formed therethrough, and wherein said movable window panel is movable between said closed position and said opened position relative to said opening, and wherein an electrical element is established at a surface of said fixed window panel at opposite sides of said opening.

6. The rear slider window assembly of claim 1, wherein a wire guide is disposed at said fixed window panel and wherein said flexible cable is routed along said wire guide.

7. The rear slider window assembly of claim 6, wherein said wire guide has an arcuate inner surface that curves along the length of said wire guide and wherein said flexible cable engages said arcuate inner surface as said movable window panel is opened and closed.

8. The rear slider window assembly of claim 1, wherein said flexing direction is generally horizontal when said rear slider window assembly is mounted in the vehicle.

9. A rear slider window assembly for a vehicle, said rear slider window assembly comprising:

a frame portion having an upper rail and a lower rail;

a fixed window panel that is fixed relative to said frame portion;

a movable window panel that is movable along said upper and lower rails, wherein said movable window panel is movable between a closed position and an opened position;

wherein said movable window panel has a first electrical element established at a surface of said movable window panel, and wherein said first electrical element comprises a heater grid;

wherein said fixed window panel has a second electrical element established at a surface of said fixed window panel, and wherein said second electrical element comprises a heater grid;

wherein said first electrical element is in electrical connection with a power source of the vehicle and remains in electrical connection with the power source of the vehicle irrespective of whether said movable window panel is in said opened position or said closed position;

wherein said first electrical element is in electrical connection with the power source of the vehicle via a flexible cable that has one end secured to and electrically connected to a first electrical connector at said first electrical element at said movable window panel, and wherein another end of said flexible cable is secured to and electrically connected to a second electrical connector at said fixed window panel;

wherein said flexible cable flexes in response to movement of said movable window panel relative to said fixed window panel;

wherein a wire guide is disposed at said fixed window panel and wherein said flexible cable is routed along said wire guide;

wherein said wire guide has an arcuate inner surface that curves along the length of said wire guide and wherein said flexible cable engages said arcuate inner surface as said movable window panel is opened and closed;

wherein said flexible cable comprises conductive wires disposed in and along an overmolded serrated polymeric wire sheath;

wherein said flexible cable is flexible in a flexing direction while being substantially non-flexible in a non-flexing direction, said non-flexing direction being generally transverse to said flexing direction, and wherein said flexing direction is generally horizontal when said rear slider window assembly is mounted in the vehicle; and

wherein said serrated polymeric wire sheath has serrations along one side region of said serrated polymeric wire sheath so as to be flexible in said flexing direction while being substantially non-flexible in said non-flexing direction.

10. The rear slider window assembly of claim 9, wherein said first and second heater grids comprise a plurality of electrically conductive traces disposed at said respective window panels.

11. The rear slider window assembly of claim 9, wherein said fixed window panel comprises a first fixed window panel and wherein said rear slider window assembly comprises a second fixed window panel with an opening between said first and second fixed window panels, and wherein said movable window panel is movable between said closed position and said opened position relative to said opening, and wherein each of said fixed window panels has an electrical element established at a surface of the respective fixed window panel.

12. The rear slider window assembly of claim 9, wherein said fixed window panel comprises a single panel with an aperture formed therethrough, and wherein said movable window panel is movable between said closed position and said opened position relative to said opening, and wherein an electrical element is established at a surface of said fixed window panel at opposite sides of said opening.
