摘要： A heating pad (1), particularly for vehicle seats, has an electrically insulated heating wire (2) laid in loops between a first covering layer (3) and an intermediate layer (4) united therewith, the opposite side of the intermediate layer being joined to a second covering layer (5). The intermediate layer (4) has a thickness which is at least twice as great as the diameter of the wire (2) and is of a soft and elastic material, suitably foamed plastics, such as to enable the wire to be impressed in said layer with the aid of the first covering layer, while retaining a smooth surface on the first layer (3). The heating wire (2) has a hard insulation of preferably polyetrafluoroethene, and can be elastically moved to one side by a sharp object which penetrates into the heating pad. The pad can be used to advantage in vehicle seats, where it can be sewn directly onto the inside of the seat covering. In a method of producing such a heating pad, a lower part (4, 5) included in the pad is placed on support means equipped with pins, after which the heating wire is laid out in a pattern determined by the pins. A covering layer (3) is then applied.
