Heating device for use as accessory for heating human body in e.g. electric blanket, has flexible surface including electric heaters i.e. flexible resistor cords, and control unit to vary electrical power supplied to each resistor cord
The device has a flexible surface including flexible electric heaters i.e. flexible resistor cords (21-23) intended to heat a part of the flexible surface. A control unit (3) is provided to automatically vary the electrical power supplied to each flexible resistor cord. The control unit is programmable to process information provided by a temperature sensor, where the flexible surface has a shape of a mattress, or a blanket, or a sleeping bag. The control unit is powered by a mains connection (5).
