Controllably heated clothing
First Claim
1. In heated clothing, the combination comprising(a) multiple clothing sections adapted to cover different portions of the human body,(b) electrical wires carried by said sections and including bus wires and heater wires, said bus and heater wires being electrically insulated, and(c) means including a temperature control connected in series with said wires for controlling battery powered electrical current flow to said bus and heater wires, and including manually operable switch means connected in series with at least one of said heater wires for interrupting current flow thereto without requiring disconnection of bus wires,(d) there being a temperature sensor adapted to be carried by the wearer of the clothing to sense wearer'"'"'s body heating of the clothing, said sensor connected in controlling relation with said temperature control to cause an increase in current flow to said wires in response to a predetermined lowering of sensed body generated heating of the clothing,(e) and structure to contain said control and to attach the control to the wearer'"'"'s clothing with the sensor carried by said structure to be exposed toward the wearer'"'"'s body.
