1. An interior trim for a passenger compartment of a vehicle, comprising:
a first carrier, said first carrier having an inner side that faces the passenger compartment, and an outer side that is directed away from the passenger compartment, wherein the first carrier has a variable thickness defined by a unitary matrix; and
a heating element arranged on the outer side, wherein the first carrier comprises:
the matrix, wherein the matrix is divisible into polygonal pockets, wherein each polygonal pocket is bounded by the outer side and the inner side such that the polygonal pockets have a variable thickness between the outer side and the inner side that corresponds to the variable thickness of the first carrier; and
a filler, the filler having a thermal conductivity that is higher than that of the matrix whereby heat generated by the heating element is directed through the filler into the passenger compartment, wherein the interior trim is arranged on a headliner, wherein the filler contains a boron nitride, which has a thermal conductivity of up to 400 W/mK; and
the first carrier comprises a first plastic, wherein said first plastic is selected from a first group consisting of polypropylene, PP-TD20, acrylonitrile-butadiene-styrene (ABS), a polyamide (PA) and combinations thereof, and the matrix comprises a second plastic, wherein a second carrier is arranged on the heating element and the heating element is arranged between the first carrier and the second carrier, wherein the second carrier comprises a third plastic, where said third plastic is selected from a second group consisting of polypropylene, PP-TD20, acrylonitrile-butadiene-styrene (ABS), a polyamide (PA) and combinations thereof, wherein the second carrier contains polyurethane, which is reinforced by fiber mats and has a paper backing.
