1. A method for manufacturing a decorative component of an interior trim of a passenger compartment having a raised embossed visible surface, said method comprising the acts of:
providing an embossing device which has female embossing mold and male embossing mold;
providing at least one decorative material layer;
disposing the decorative material layer between the female embossing mold and the male embossing mold in such a manner that a visible surface of the decorative material layer faces the female embossing mold, and a reverse face of the decorative material layer that is opposite the visible surface faces the male embossing mold;
carrying out an embossing procedure by means of the embossing device such that the decorative material layer after the embossing procedure has a raised region on the visible surface, and opposite thereto a depressed region on the reverse face;
producing an insert element by means of an additive production method, the insert element having a predefined resilience and elasticity;
controlling the resilience and elasticity of the insert element by changing the cell size, cell geometry, cell wall thickness, and cell count of the cellular-type construction of the insert element;
configuring a multiplicity of recesses in the cellular-type construction of the insert element such that a predefined compression hardness of the insert element is achieved; and
disposing the insert element for stabilizing the raised region in the depressed region of the decorative component of the interior trim of a passenger compartment, wherein
the insert element has an elasticity modulus of less than or equal to 5.0 GPa, and
wherein the at least one decorative material layer is made of leather and has thickness, at the embossed region, between 2 mm and 5 mm.
