1. A process for producing trim panels of motor vehicles with linings on a visible surface made of real leather, artificial leather and/or textiles, wherein (a) in a first step, a pre-sewn cover (1) is prepared from different blanks made of real leather, artificial leather and/or textiles;(b) in a second step, the pre-sewn cover (1) is mounted onto a positive mold (2) having the geometry of a trim support (5);characterized in that, in the second step, existing seams (3a, 3b, 3c, 3d) are adjusted and fixed on said positive mold (2) by applying reduced pressure on a backside of the pre-sewn cover (1);(c) in a third step, said positive mold (2) with said pre-sewn cover (1) is transferred into a lining mold (3);(d) in a fourth step, said positive mold (2) is removed after the reduced pressure on the positive mold (2) has been switched off, and said pre-sewn cover (1) is fixed within the lining mold (4) by reduced pressure on the visible side; and(e) in a fifth step, a trim support (5) provided with an adhesive coating is lined with said pre-sewn cover (1) with at least one bead (6) congruent thereto that is congruent to the seams (3a, 3b, 3c, 3d) is employed in the region of transition from a visible surface to a standing edge of the trim support towards a door panel (8), wherein the at least one bead is formed into substantially an L-shape in vertical cross section, one end of the bead is engaged to a side of the visible surface of the trim support, and the other end is connected to a side of the standing edge of the trim support. 2. The process according to claim 1, characterized in that soft inserts made of foam and/or non-woven are provided in desired regions on the inner sides of the pre-sewn cover (1) in an intermediate step before the first step and before the second step. 3. The process according to claim 1, characterized in that the blanks are prepared with different colors. 4. The process according to claim 1 with a visible surface made of real leather, characterized in that a leather blank is lined with a foam blank containing polypropylene/polyethylene or polyurethane. 5. The process according to claim 1, characterized in that a pre-sewn cover (1) having functional and/or ornamental seams (3a, 3b, 3c, 3d) is employed. 6. The process according to claim 1, characterized in that the lining is effected by means of punch pressure. 7. The process according to claim 1, characterized in that a pre-sewn cover (1) is employed whose lining backside is provided with a full-area foam and/or non-woven. 8. Trim panels of motor vehicles with linings on the visible surface made of real leather, artificial leather and/or textiles obtainable according to any of claims 1 to 7, comprising a door trim support (5) and a visible surface of a pre-sewn cover (1) made of leather, artificial leather and/or textiles that also has at least one or several functional seams (3a, 3b, 3c) in addition to ornamental seams (3d), characterized in that the backsides of the functional seams (3a, 3b, 3c) are provided with perfect fit in at least one circumferential bead (6) in the region of transition from the visible surface to a standing edge towards a door panel (8), wherein the circumferential bead is formed into substantially an L-shape in vertical cross section, one end of the bead is engaged to a side of the visible surface of the trim support, and the other end is connected to a side of the standing edge of the trim support. 9. The trim panels according to claim 8, comprising door trims, roof pillars or trims in the region of the instrument panel of motor vehicles.
