Electrical heating element for vehicle steering wheel has non-conducting auxiliary filament sewn onto carrier at attachment points on both sides of line to form loops with which heat conductor is attached without penetrating heat conductor

摘要

The device has a flat and flexible, especially textile, carrier (12) and at least one elongated flexible heat conductor (14) laid on the carrier along a line and fixed to it with an electrically non-conducting auxiliary filament (16) that is sewn onto the carrier so that it penetrates into the carrier at a number of attachment points (20) on both sides of the line to form a number of loops (18) with which the heat conductor is attached to the carrier without penetrating the heat conductor : An independent claim is also included for a heated steering wheel for a vehicle.
