Abstract

A vehicle window glass mounted in a vehicle component and movable to open and close a window is disclosed. The window glass may comprise a generally vertical first side edge; a generally vertical second side edge in opposed relation to the first side edge; and a bottom edge extending between the first side edge and the second side edge and including a first downward sloping portion extending from the first side edge in a downward sloping direction and a first drip notch recessed into the bottom edge along the first downward sloping portion, whereby water wicking along the first downward sloping portion of the bottom edge will drop from the window glass when the water makes contact with the first drip notch.

Claims (17)

1. A vehicle window glass mounted in a vehicle component and movable to open and close a window, the window glass comprising:

a generally vertical first side edge;

a generally vertical second side edge in opposed relation to the first side edge; and

a bottom edge extending between the first side edge and the second side edge and including a first downward sloping portion extending from the first side edge in a downward sloping direction and a first drip notch recessed into the bottom edge along the first downward sloping portion, whereby water wicking along the first downward sloping portion of the bottom edge will drop from the window glass when the water makes contact with the first drip notch.

2. The vehicle window glass of claim 1 wherein the bottom edge includes a second downward sloping portion extending from the second side edge in a downward sloping direction and a second drip notch recessed into the bottom edge along the second downward sloping portion, whereby water wicking along the second downward sloping portion of the bottom edge will drop from the window glass when the water makes contact with the second drip notch.

3. The vehicle window glass of claim 2 wherein the bottom edge includes a generally horizontal central portion extending between the first downward sloping portion and the second downward sloping portion.

4. The vehicle window glass of claim 1 wherein the first drip notch has an arcuate portion having a diameter of 12 to 13 millimeters.

5. The vehicle window glass of claim 1 wherein the vehicle component is a door and the window glass is configured to slide up and down in the door.

6. A window assembly for use in a vehicle component and movable between an open and a closed position, the window assembly comprising:

a window glass including a generally vertical first side edge; a generally vertical second side edge in opposed relation to the first side edge; and a bottom edge extending between the first side edge and the second side edge and including a first downward sloping portion extending from the first side edge in a downward sloping direction and a first drip notch recessed into the bottom edge along the first downward sloping portion, whereby water wicking along the first downward sloping portion of the bottom edge will drop from the window glass when the water makes contact with the first drip notch;

a first glass run channel that receives and guides the first side edge;

a second glass run channel that receives and guides the second side edge; and

a window regulator mounted to the window glass and configured to move the glass between the open and closed positions.

7. The window assembly of claim 6 wherein the bottom edge includes a second downward sloping portion extending from the second side edge in a downward sloping direction and a second drip notch recessed into the bottom edge along the second downward sloping portion, whereby water wicking along the second downward sloping portion of the bottom edge will drop from the window glass when the water makes contact with the second drip notch.

8. The window assembly of claim 7 wherein the bottom edge includes a generally horizontal central portion extending between the first downward sloping portion and the second downward sloping portion, and the window regulator is mounted to the central portion.

9. The window assembly of claim 6 wherein the first drip notch has an arcuate portion having a diameter of 12 to 13 millimeters.

10. The window assembly of claim 6 wherein the vehicle component is a door having a door inner panel, and the window regulator, the first glass run channel and the second glass run channel are mounted to the door inner panel.
