Abstract

A heated garment is disclosed for use by a wearer to impart heat to the wearer in cold conditions. The heated garment includes a wearable garment having an interior portion that resides adjacent a wearer'"'"'s body. At least one heating pad is disposed in the wearable garment and the heating pad is configured, when heated, to radiate heat from the interior portion of the garment to a wearer. The heating pad comprises at least one heating element fixed to or otherwise incorporated into a flexible carrier. The heating element is configured on the carrier such that, when heated, the heating element produces on the carrier a field of warmth characterized by a plurality of areas of increased thermal energy relative to other areas on the carrier. A power supply is configured to supply operating voltage to the heating element when heat is desired and a controller is used to control the power supply.

Claims

1. A heated garment for use by a wearer to impart heat to the user in cold conditions, the heated garment comprising:

a wearable garment having an interior portion;

at least one heating pad in the wearable garment configured, when heated, to radiate heat from the interior portion of the garment to a wearer of the garment;

the heating pad comprising at least one heating element fixed to a carrier, the heating element being configured on the carrier such that, when heated, the heating element produces on the carrier a plurality of areas of increased thermal energy relative to other areas on the carrier;

a source of electrical power arranged to supply operating voltage to the heating element when heat is desired.

2. The heated garment of claim 1 wherein the at least one heating element is configured such that the heating element crosses over itself to produce the plurality of areas of increased thermal energy within the areas of increased thermal output.

3. The heated garment of claim 1 wherein the at least one heating element is configured such that the heating element comes into close proximity to itself to produce the plurality of areas of increased thermal energy.

4. The heated garment of claim 1 further comprising a plurality of heating pads located at different locations within the garment to apply heat to selected areas of the body of the wearer.

5. The heated garment of claim 1 further comprising an insulating material impregnating the carrier.

6. The heated garment of claim 5 wherein the insulating material comprises a polymer.

7. The heated garment of claim 5 wherein the insulating material comprises a plastic.

8. The heated garment of claim 5 wherein the insulating material comprises a silicone.

9. The heated garment of claim 8 wherein the silicone impregnates the heating pad to protect and insulate the heating element.

10. The heated garment of claim 1 wherein the heating pad forms the inner lining of the garment.

11. The heated garment of claim 10 wherein the garment is a glove having finger sheaths and the heating pad carries a heating element configured to surround substantially the entire outer periphery of the finger sheaths.

12. The heated garment of claim 1 further comprising a power supply capable of supplying an operating voltage to the heating element to cause the heating element to conduct current and be warmed.

13. The heated garment of claim 12 further comprising a controller coupled to the power supply, the controller being configured to vary at least one characteristic of the operating voltage in order to control the warmth of the heating element.

14. The heated garment of claim 13 wherein the at least one characteristic is selected from a group consisting essentially of voltage level, on-duration, and off-duration.

15. A pad configured to be incorporated in a garment to convey heat to the body of a wearer of the garment, the pad comprising:

a carrier being sufficiently flexible to move with a wearer'"'"'s body;

a heating element incorporated into the carrier, the heating element warming in response to application of an operating voltage to the heating element;

the heating element being arranged on the carrier to produce a field of warmth characterized by isolated areas of increased thermal energy in response to application of the operating voltage.

16. The pad of claim 15 wherein the heating element comprises an elongated conductive strand having a predetermined resistance per unit length.

17. The pad of claim 16 wherein the strand is arranged on the carrier to cross over itself at the isolated areas to increase the thermal mass and thus thermal energy within the isolated areas.

18. The pad of claim 17 further comprising a protective material incorporated into the carrier to protect the heating element from environmental hazards.

19. The pad of claim 18 wherein the protective material comprises a polymer.

20. The pad of claim 18 wherein the protective material comprises a silicone.

21. The pad of claim 20 wherein the silicone is impregnated into the material of the carrier to surround and protecting the heating element incorporated therein.

22. The pad of claim 15 wherein the heating element comprises an elongated wire.

23. The pad of claim 15 wherein the heating element comprises conductive yarn sewn into the fabric of the carrier.
