ABSTRACT:

BACKGROUND OF THE INVENTION
1. Technical Field
This device relates to electrical devices for applying heat to the body of a person by electric resistant wires and more specifically heating pads made of flexible fabric material with a plurality of loop heating wires defining a circuit within.
2. Description of Prior Art
Prior art devices of this type are generally referred to as electric blankets and heating pads. The electric blankets are generally used on beds to add additional heat to the sleeping environment. Heating pads are typically smaller and provide heat to specific portions of the user's body. These devices have electrical resistant heating wires positioned within. See for example U.S. Pat. Nos. 2,281,578, 4,736,088 and 5,151,578.
In U.S. Pat. No. 3,281,578 an electric heating mat is disclosed having a main body member with a plurality of heating elements within.
U.S. Pat. No. 4,736,088 is directed to a therapeutic heating pad and hand muff having a laminated structure which directs the flow of heat into the effective body member.
U.S. Pat. No. 5,151,578 discloses an anisotropically bendable heating pad having stiffening member channels that provide indirect stiffness thereto.
SUMMARY OF THE INVENTION
An electrical heating surface for a child's car seat having a contoured fabric body member with an enclosed electrical resistant wire loop. Apertures are provided within the surface to correspond to the access openings for the seat belt harness in the seat that secures a child and holds the child within. Attachment elements extend from the heating surface to secure same within the car seat. An electrical connection is provided to the automobile power supply which is thermostatically controlled to regulate heat output. Portions of the heating surface are contoured and adaptable to engage and hold within the car seat allowing access to the child safety harness.
