Abstract

A detachable heatable coat liner including two front panels and a back panel joined together by a waist belt, each panel having a fire retardant layer to which is attached a length of electric resistance wire, a layer of fabric with a coating of "Teflon" positioned such that the coating lies against the resistance wire, and two outside layers of coat fabric enclosing the other two layers, a lead wire connecting all lenths of resistance wire and a plug attachable to a source of power, the liner being attachable to the coat by strips of "Velcro" fastener.

Claims

1. A coat liner comprising a back panel, a left front panel and a right front panel, each said panel adapted to be attached to the inside of a coat, each said panel including a layer of fire retardant fabric having two surfaces and a pattern of electric resistance heating wire attached to one said surface thereof, a layer of fabric having two sides and coated on one side with a polyfluorocarbon resin, said resin coating lying against said heating wire, and a layer of coating fabric lying against the other of said sides of said fabric, and an electrically insulated wire connecting said heating wire to a plug attachable to a source of electric power.

2. The coat liner of claim 1 which additionally comprises a second layer of coating fabric lying against the other of said surfaces of said layer of fire retardant fabric.

3. The coat liner of claim 1 wherein said polyfluorocarbon resin is polytetrafluoroethylene.

4. The coat liner of claim 1 wherein said fire retardant fabric is Nomex.

5. The coat liner of claim 1 which additionally comprises strips of fabric hook fastener and said garment includes corresponding strips of fabric loop fastener.

6. A vest liner attachable to the inside of a vest to enhance the warmth of the vest, the liner comprising a right front panel, a left front panel, and a back panel attached to each other by a waist belt, each said panel detachably attachable to the inside of said vest by cooperating strips of fabric hooks on said liner and fabric loops on said vest;

said panels each comprising two outer layers of coating fabric and two inner layers stitched together to form a four-layered panel;

one of said inner layers being a fire retardant fabric with at least one length of an electric resistant nickel-copper wire attached thereto in a pattern substantially equally distributed over the surface of said fire retardent panel, and the other of said inner layers being a fabric coated on one side with polytetrafluoroethylene, said polytetrafluoroethylene coating being in contact with said nickel-copper wire, and an insulated lead wire attached to each said length of nickel-copper wire and having a plug available outside said liner which is attachable to a source of electric power.

7. The liner of claim 6 wherein said first retardant fabric is Nomex.

8. The liner of claim 6 wherein said source of power is of a 12-volt D.C. electric output.
