Abstract

The present invention relates to a garment assembly including an outer layer selected from any separately manufactured outer layer and a liner covering an inner surface of the outer layer. The inner layer includes a fabric layer, at least one flexible heating element affixed to the fabric layer, a controller electrically connected to the heating element, a portable power supply electrically connected to the controller and the heating elements; electrical leads affixed to the fabric layer to provide an electrical connection between the portable power supply, the controller and the at least one heating element, and at least one closeable pocket for housing the controller and the portable power supply. The present invention further relates to a rechargeable battery pack for seasonal use in a heated garment having at least one battery and battery control circuit having a current drain on said at least one battery maintained within a self-contained housing. The battery further includes a switch located between the battery and battery control circuit operative to, during long periods of non-use, create an open circuit between the battery and the battery control circuit.

Claims

1. A garment assembly comprising:

an outer layer selected from any separately manufactured outer layer;

a liner covering an inner surface of said outer layer including;

a fabric layer;

at least one flexible heating element affixed to said fabric layer;

a controller electrically connected to said heating element;

a portable power supply electrically connected to said controller and said heating elements;

electrical leads affixed to said fabric layer to provide an electrical connection between said portable power supply, said controller and said at least one heating element; and

at least one closeable pocket for housing said controller and said portable power supply.

2. The garment assembly of claim 1 wherein:

said liner includes a perimeter for affixing said liner to said outer layer.

3. The garment assembly of claim 2 wherein said perimeter includes an excess portion of said fabric layer to conform said liner for attachment to said outer layer.

4. The garment assembly of claim 3 wherein conforming said liner size along said perimeter by hemming or cutting away a portion of said perimeter.

5. The garment assembly of claim 3 wherein said liner is affixed to said outer layer.

6. The garment assembly of claim 5 wherein said liner is affixed by sewing to said outer layer to form a seam.

7. The garment assembly of claim 5 wherein said liner and said outer layer are removably affixed by fasteners consisting of the group selected from a zipper, buttons, hook and loop material and any combination thereof.

8. The garment assembly of claim 1 wherein said at least one pocket includes an adjustable opening having a first opening size for accessing said controller during operation and a second opening size for insertion and connection said controller.

9. The garment assembly of claim 8 wherein said adjustable opening includes a stop flap to prevent opening to said second opening size.

10. The garment of claim 8 wherein said at least one pocket is two pockets with a first pocket sized to hold said battery and a second pocket is sized to hold said controller.

11. The garment of claim 10 wherein said second pocket is an inner breast pocket to facilitate access to said controller.

12. An inner liner for attachment to an outer garment layer comprising:

a fabric layer;

a heated garment circuit having;

at least one flexible heating element affixed to the fabric layer;

a controller electrically connected to the heating element;

a portable power supply electrically connected to the controller and the heating elements; and

electrical leads affixed to the fabric layer to provide an electrical connection between the portable power supply, the controller and the at least one heating element; and

at least one closeable pocket for housing one of the controller and the portable power supply

wherein said heated garment circuit is provided independent of said outer garment layer.

13. The inner layer of claim 12 further including a plurality of strain reliefs to protect the integrity of the electrical circuit.

14. The inner layer of claim 12 wherein said at least one heating element is a plurality of flexible carbon fiber conductors formed loosely into at least one discrete bundle.

15. The inner layer of claim 13 wherein a strain relief is affixed to the inner layer and electrical leads extending between components selected from the group consisting of the controller and the portable battery supply, the heating element and the portable battery supply, the controller and the heating element and any combination thereof.

16. The inner layer of claim 13 wherein a first cable plug and socket in an electrical lead from said controller and said at least one heating element allow for disconnection of said controller from said at least one heating element and strain reliefs are provided at a junction of the electrical leads to the socket and the plug;

and

wherein a second cable plug and socket in an electrical lead from said controller and said portable power supply allow for disconnection of said controller from said portable power supply and strain reliefs are provided at a junction of the electrical leads to the socket and the plug.

17. The inner layer of claim 16 wherein at least one of said cable plugs and sockets include a water resistant cap.

18. The inner layer of claim 12 wherein said at least one pocket further includes a first pocket for housing said portable power supply and a second pocket having a closeable opening for holding said controller, said closeable opening includes two opening positions where a first opening position is large enough for access to the controller and a second opening position is large enough for insertion and connection of the controller to said electrical leads.

19. The inner layer of claim 18 wherein an opening stop is disposed along said closeable opening to prevent opening of said closeable opening beyond said first opening position.

20. The inner layer of claim 12 further including a first pocket for housing said portable power supply and a second pocket having a closeable opening for holding said controller, a portion of said pocket wall includes a light transmissive material for feedback from said controller.

21. The inner layer of claim 12 wherein said portable power supply is a battery pack having a housing enclosing a battery and a battery control circuit, the battery pack further includes a switch located between the battery and battery control circuit that is operative to, during long periods of non-use, create an open circuit between the battery and the battery control circuit;

and

wherein said controller further includes a switch to control power from the battery to the heating element during normal use.

22. A rechargeable battery pack for seasonal use in a heated garment comprising:

at least one battery;

a battery control circuit having a current drain on said at least one battery;

a self-contained housing for enclosing the battery and battery control circuit;

a switch located between the battery and battery control circuit operative to, during long periods of non-use, create an open circuit between the battery and the battery control circuit.

23. The rechargeable battery pack of claim 22 in combination with said heated garment wherein said heated garment includes at least one heating element.

24. The rechargeable battery pack of claim 22 wherein said battery is a lithium battery.

25. The rechargeable battery pack of claim 22 wherein said heated garment includes at least one heating element and said switch is not used during operation of said heated garment to activate said at least one heating element.
