ABSTRACT:
Improved vehicle seats can be made in a process in which the seat-covering material and a flat heater are inserted into a negative mold for a vehicle seat and the mold is filled with in-situ foam because the flat carrier for the heating conductor of the heater is constituted by a braided wide-mesh grid made of plastic strings or plastic yarns, which during the filling of the negative mold for vehicle seats with in-situ plastic foam are surrounded by the foam substantially without a change of the porosity of the plastic foam.
