Abstract

An electrically heated vest which is comprised of interchangeable designed modules including at least one heating element, a removable wiring harness, a machine washable shell, and a power cord with thermostat. The interchangeable modules are anatomically shaped and identically sized. The modules are fastened to the vest via snaps, buttons, VELCRO®, or equivalent. The wiring harness is removable from the vest and has quick disconnects for the modules and power cord. The vest is machine washable, has mating fasteners for the heating elements, and an inner liner and outer shell between which the modules are attached.

Claims

1. An electrically heated vest comprising:

an outer shell and an inner liner having a perimeter, the outershell being attached to the inner liner around a substantial portion of the perimeter to form a cavity therebetween;

a plurality of interchangeable, identically sized modules each including a heating element, the modules removably fastenable between the outer shell and the inner liner within the cavity;

a wiring harness having a plurality of electrical connectors operatively connected to at least one heating element of each module and removably fastenable between the outer shell and the inner liner within the cavity; and

a power supply cord connected to the wiring harness and having a power control and an electrical connector operatively attached to a source of electrical power;

the modules, wiring harness and power supply cord being removably fastened to the outer shell for repair or replacement.

2. The electrically heated vest of claim 1 wherein each of the interchangeable modules is removably fastenable using at least one fastener located on the front side and the back side of the module.

3. The electrically heated vest of claim 2 wherein the wiring harness defines a parallel circuit when connected to the modules.

4. The electrically heated vest of claim 2 wherein the power control includes a feedback loop.

10. The electrically heated vest of claim 1 wherein said plurality of interchangeable, identically sized modules include four of said modules.

11. The electrically heated vest of claim 1 wherein said heating element is a resistive fabric panel.

5. An electrically heated vest comprising:

a fabric shell that defines openings for arms, head, and waist having an inner liner defining a liner periphery and an outer shell defining a shell periphery, at least a portion of the peripheries secured together;

a plurality of interchangeable, identically sized modules each including a heating element having an electrical connector and means for attachment to the fabric shell;

a removable wiring harness disposed between the inner liner and the outer shell having a plurality of electrical connectors for providing power to the modules;

a power supply cord, a means for controlling power and an electrical connector for providing power to the wiring harness;

the plurality of interchangeable modules being disposed between the inner liner and the outer shell and removably attached to the fabric shell;

the removable wiring harness being removably connected to the plurality of modules; and

the power supply cord being removably connected to the wiring harness;

whereby the modules, the wiring harness, and the power supply cord are removable from the fabric shell.

6. The electrically heated vest of claim 5 wherein each interchangeable module has a front side and a back side;

and

the means for attachment of the modules includes one or more fasteners located on the front side and the back side of each module.

7. The electrically heated vest of claim 6 wherein the wiring harness defines a parallel circuit when connected to the modules.

8. The electrically heated vest of claim 6 wherein the means for controlling power includes a feedback loop.

9. The electrically heated vest of claim 6 wherein the wiring harness is attached to the fabric shell using a removable tie strap.

12. The electrically heated vest of claim 5 wherein said plurality of interchangeable, identically sized modules include four of said modules.

13. The electrically heated vest of claim 5 wherein said heating element is a resistive fabric panel.
