  • METHOD AND APPARATUS FOR A HEATED COMFORTER
    Publication number: 20090008376
    Abstract: An electrically heatable comforter is formed from upper and lower fabric outer layers extending generally parallel to each other and being closed along the edges of the layers to form a shell. One or more interior panels extend between the outer layers, and have respective ends connected to, the upper and lower outer layers. The comforter further includes a sleeve that is fixed to the interior panels and is spaced from their connections to the upper and lower layer. A heating wire is located within at least a portion of the sleeve in order to hold the heating wire away from the outer surfaces of the comforter and to keep the wire from moving about. In addition, the comforter can be stuffed with a fill material located inside the comforter shell on at least one side of the interior panels.
