Abstract

Abstract A seat heater for integrated assembly into car seats has at least two or several segments and faces, respectively, of any desired shaping. The heater includes several flat, electrically interconnected resilient heating elements (1.1/1.2) either forming a coherent heating face (1) or conforming to the section-wise individual seat configuration, especially the shaping thereof, with the connection between the individual heating elements (1.1/1.2) being respectively established by a low-strength electrical conductor (3) and the electrical conductor (3) being guided in an insulating resilient sheathing (6) of silicone rubber or the like engaging, at both ends, in partial lengths, each of the heating elements (1.1/1.2 et seq).
