Abstract

A window formed by a glass pane for use as a window for a vehicle. The window is supported by structure carried by the body of the vehicle to move about an axis thereby to swivel between positions of opened and closed. The window supports an electric consumer and electrical conducting strips are carried by the window for use in connecting the electric consumer to a source of power supplied by the vehicle.

Claims

1. A window for use with a vehicle comprised of safety glass and an electric motor carried by said window, means supporting said window on said vehicle for movement about a pivot axis, said pivot axis being located adjacent an edge of said window and said electric motor disposed adjacent another edge of said window, conducting means characterized by current feed lines for the electric motor, said current feed lines formed of conducting strips disposed within the region of the edges of said window and along the edges of said window, said conducting strips comprised of a conductive enamel composition including silver particles, and connector means carried by said conducting strips adapted for connecting said conducting strips both to a power source of said vehicle and said electric motor.

2. The window of claim 1 wherein said pivot axis is located adjacent the upper edge of said window, and said electric motor is disposed adjacent the lower edge of said window, and wherein the conducting means is disposed along the upper and lower as well as the side edges of said window and within the region of the edges of the window.

3. The window of claim 1 wherein a galvanic metal preciptation serves to reinforce said conducting strips.

4. The window of claim 1 wherein the means supporting said window comprises a pair of hinges, each hinge including a pair of arms extending from a pin which defines said pivot axis, one of said arms of each hinge connected to said window and the other arm of each hinge adapted to be connected to said vehicle.

5. The window of claim 1 wherein said window comprises a frameless prestressed glass pane.

6. The window of claim 1 further including means providing a heating resistance including a family of current feed lines, said current feed lines connected to said conducting strips.

7. In combination, a vehicle including a body, means forming an opening on said body, said opening forming means defined by a lip extending into said opening, a window of safety glass for closing said opening, means including a pair of arms extending from a pin supporting said arms at one end about which said arms may pivot, means attaching the other end of one of said arms adjacent an edge of said window and the other end of the other of said arms to said body so that said window may move between a first, opened position and a second, closed position at which said window is supported by said lip, an electric motor carried by said window, said electric motor having a mounting base carried by said window adjacent another edge thereof, conducting means characterized by current feed lines for said electric motor, said current feed lines formed of conducting strips disposed both within the region of the edges of said window and along the edges of said window, said conducting strips comprised of a conductive enamel composition including silver particles, and connector means carried by said conducting strips adapted for connecting said conducting strips both to a power source of said vehicle and said electric motor.

8. The combination of claim 7 wherein said pivot is located adjacent the upper edge of said window, and said electric motor is located adjacent the lower edge of said window.

9. The combination of claim 7 including a member supported by said lip around said opening, said member being formed of a material capable of undergoing deformation when said window is in the second, closed position thereby to seal said opening.

10. The combination of claim 7 wherein said window comprises a frameless, prestressed glass pane.

11. The combination of claim 7 further including means providing a heating resistance including a family of current feed lines, said current feed lines connected to said conducting strips.
