摘要

The area to be heated is fitted with parallel heating wires each in a meandering lay-out (1). The ends of the wires are contacted by edge connector wires (2) which are also shaped into a meandering pattern. This provides more than one electric contact point between each contact wire and the corresp. heater wire. The heater wires are arranged in the required heating pattern and the contact wires can be applied via a support strip. The contact strips are sewn on to the cushion and on to the heater wire pattern. The heaters can have a thin wire gauge and are easily hidden in the cushion material. The completed heater pattern can be applied as a flexible addition to the cushion covering. ADVANTAGE - Even heating control, unobtrusive heaters, efficient contact between heaters and supply.
