1 - 6 . (canceled) 
     
     
         7 . Interior trim components of motor vehicles consisting of a component support ( 1 ) and at least two decorative layers ( 2   a,    2   b ) two-dimensionally bonded thereto with a respectively defined surface and/or color profile of the decorative layers ( 2   a,    2   b ), obtainable by a process wherein
 in a first step, the respective visible sides ( 3   a,    3   b ) of the respective decorative layers ( 2   a,    2   b ) are heated to the respectively desired graining temperatures in the range of from 180 to 220° C., the back sides of the decorative layers ( 2   a,    2   b ) are heated to the respective molding temperatures in the range of from 130 to 170° C., and in a respectively grained mold, the respective molded part geometry and simultaneously the corresponding surface graining of decorative layers ( 2   a,    2   b ) are prepared by pressing, blow molding and/or deep drawing;   in a second step, the edges of the respective decorative layers ( 2   a,    2   b ) are trimmed as necessary;   in a third step, decorative layers ( 2   a,    2   b ) positioned in mutual orientation and fixed by reduced pressure; and   in a fourth step, the oriented decorative layers ( 2   a,    2   b ) are transferred to a backing mold and backed in a per se known manner with the component support ( 1 ) on the surface opposite to the visible sides ( 3   a,    3   b ).   
     
     
         8 . Interior trim components according to  claim 7 , characterized in that said component support ( 1 ) comprises a door trim support, especially based on natural-fiber reinforced polymer materials. 
     
     
         9 . Interior trim components according to  claim 8 , characterized in that the material of said door trim support is selected from natural fiber/polypropylene material, natural fiber/polyurethane material, natural fiber/epoxy resin material, ABS, ABS/PC, PP or polyamide. 
     
     
         10 . Interior trim components according to  claim 7 , characterized in that said decorative layers ( 2   a,    2   b ) comprise films, especially foam-backed plastic films. 
     
     
         11 . Interior trim components according to  claim 10 , characterized in that said plastic films are selected from thermoplastic polyolefin, ASA, polyvinyl chloride and/or thermoplastic polyurethane.
