<p>PCT No. PCT/SE93/00453 Sec. 371 Date Nov. 18, 1994 Sec. 102(e) Date Nov. 18, 1994 PCT Filed May 19, 1993 PCT Pub. No. WO93/23968 PCT Pub. Date Nov. 25, 1993An electric heating device (34) in which is included an electric energy source (45) which is designed as a thin film battery (45). The heating device also includes a resistor heating unit (40) comprising a first material stratum (40) consisting of an electrically conductive polymer material with PTC properties. The resistor heating unit (40) and the electric energy source (45) are disposed adjacent to one another and form a composite unit in which the major surfaces of the first material stratum (40) and thin film battery (45), respectively, face towards one another. Electrodes (42, 43) are connected, by the intermediary of a switch (48), to the poles of the battery (45) and to the resistor heating unit (40).</p> |
