Patent ID: 8042664

Claim:
A cable retractor for paying out and retracting an electrical cable providing electrical power to an electrical load on a movable window element comprising: a first assembly having a rotatable cable spool for receiving the electrical cable for winding on the cable spool, the first assembly including a first housing having an opening therein for paying out a first end of the electrical cable wound on the spool, and at least one electrical terminal for connecting a second end of the electrical cable on the spool to one of an electrical power source or the electrical load; a second assembly having at least one electrical connection connected to the first end of the electrical cable and further being connected to the other one of the electrical load or the electrical power source; one of the first and second assemblies being mounted for movement with the movable window element and the other of the first and second assemblies being fixed; thereby to provide power to the electrical load from said electrical cable; and a guide channel disposed between the first and second assemblies for guiding said electrical cable as the electrical cable is retracted into said first housing on said cable spool as said movable window element moves such that the first and second assemblies move relatively toward each other; whereby the electrical load is provided with electrical power from the electrical power source at all positions of the movable window element.
