Abstract

Claims (29)

1. A heated sliding window assembly for a vehicle comprising:

at least one fixed window;

a rail attached to the fixed window, the fixed window including an electrical contact;

a sliding window moveable along the rail, the sliding window moveable between open and closed positions, the sliding window including an electrical contact and including a heater grid;

a drive mechanism attached to the sliding window for moving the sliding window between the open and closed positions;

an electrical circuit for carrying current to the heater grid;

a switch separate and distinct from the electrical contacts of the fixed and sliding windows, the switch disposed within the electrical circuit and wherein the switch detects movement of the sliding window and cuts off current to the heater grid when the sliding window is moved before disengagement of the electrical contacts of the fixed and sliding windows when in the closed position, wherein the switch includes a reed switch attached to the rail.

2. The heated sliding window assembly of claim 1 including a magnet attached to the sliding window.

3. The heated sliding window assembly of claim 1 including a frame mountable in an opening of the vehicle, the rail and at least one fixed window attached to the frame.

4. The heated sliding window assembly of claim 1 including a guide bracket positioned in a channel formed in the rail, the guide bracket having a slot formed therein, the slot receiving the sliding window.

5. The heated sliding window assembly of claim 1 wherein the reed switch includes a housing having a dove tail slot formed therein that mates with a corresponding feature formed on the rail enabling the housing to slide on the rail and wherein the housing includes a spring arm that engages a notch formed on the rail for positioning the housing on the rail.

6. The heated sliding window assembly of claim 5 wherein the housing includes a wire routing extension for positioning a wire relative to the rail.

7. The heated sliding window assembly of claim 1 wherein the reed switch is positioned on a ground side of the electrical circuit of the heated sliding window wherein the reed switch opens and closes to open and complete the electrical circuit allowing transmission of current and stopping transmission of current to the fixed and sliding windows.

8. A heated sliding window assembly for a vehicle comprising:

at least one fixed window, the fixed window including an electrical contact;

a rail attached to the fixed window;

a sliding window moveable along the rail, the sliding window moveable between open and closed positions, the sliding window including a heater grid, and the sliding window including an electrical contact;

an electrical circuit for carrying current to the heater grid;

a switch separate and distinct from the electrical contacts of the fixed and sliding windows, the switch disposed within the electrical circuit and wherein the switch detects movement of the sliding window and cuts off current to the heater grid when the sliding window is moved before disengagement of the electrical contacts of the fixed and sliding windows when in the closed position, wherein the electrical circuit includes a hall effect sensor linked with the switch.

9. The heated sliding window assembly of claim 8 wherein the hall effect sensor is connected to the circuit including a power source and a relay providing current to the heated sliding window assembly, the hall effect sensor sending a signal to a transistor linked with the relay on a ground side of the heated sliding window to turn the transistor on and off wherein the transistor completes or opens the circuit.

10. The heated sliding window assembly of claim 8 wherein the hall effect sensor is connected to the circuit including a power source and a relay providing current to the heated sliding window assembly, the hall effect sensor sending a signal to a transistor linked with the relay on a ground side of a relay coil to turn the transistor on and off wherein the transistor completes or opens the circuit.

11. The heated sliding window assembly of claim 8 wherein the hall effect sensor is connected to the circuit having a power source connected to the heated sliding window assembly, the hall effect sensor sending a signal to a transistor linked with a ground side of the heated sliding window circuit to turn the transistor on and off wherein the transistor completes or opens the circuit.

12. The heated sliding window assembly of claim 8 including an electrical contact positioned on the sliding window that engages and disengages another electrical contact attached to the at least one fixed window in the closed and open positions respectively.

13. The heated sliding window assembly of claim 8 including a drive mechanism attached to the sliding window for moving the sliding window between the open and closed positions.

14. The heated sliding window assembly of claim 8 including a magnet attached to the sliding window.

15. The heated sliding window assembly of claim 14 wherein the hall effect sensor detects the magnetic field of the magnet identifying movement of the sliding window and providing a signal to cut off current routed to the heater grid.

16. The heated sliding window assembly of claim 8 including at least one wire clip attached to the rail for positioning wires associated with the heated sliding window assembly.

17. The heated sliding window assembly of claim 16

wherein the wire clip includes a body having a dove tail slot formed therein that mates with a corresponding feature formed on the rail enabling the wire clip to slide on the rail, and the body including a hook shaped retaining section for housing a wire.
