Flexible heat apparatus e.g. electric blanket, has flexible thread-like heating element comprising central carrier thread consisting of multiple fibers, where heating wires are rolled up helically on carrier thread

摘要

The apparatus has a flexible thread-like heating element (1) made from flexible support material, where the heating element is intertwined with support material threads. The heating element comprises heating wires for supplying electric current over terminal ladder orientations (10, 11) attached with low voltage supply. The heating element comprises a central carrier thread consisting of multiple fibers, where the heating wires are rolled up helically on the carrier thread. Each orientation comprises two subassemblies for reconducting the current from terminal guards.
