Method for setting a leather skin (12) having an outer surface designed to be visible, includes a step of applying a rigidity increasing treatment, a step of setting the skin using a mould cooperating with the outer surface of the skin (12), one at least of the two steps being executed only locally
Method for setting a leather skin (12) having an outer surface designed to be visible, includes a step of applying a rigidity increasing treatment, a step of setting the skin using a mould cooperating with the outer surface of the skin (12), one at least of the two steps being executed only locally at an elongated part (B) spaced apart from the edge of the skin (12) and substantially parallel to the edge, and a step for facilitating the maintenance of the shape by locally applying a shape maintaining material to the inner surface of the skin (12), in particular a thermoplastic resin (24). The invention is useful for making automotive interior trim.

The invention claimed is: 1. A method for shaping a leather skin having an outer face which is intended to be visible and an inner face, comprises comprising the following steps: applying a treatment only locally to a first elongate region of the inner face of the leather skin, the first elongate region, being located remote from the edge of the skin and substantially parallel to the skin, without applying the treatment to the region of the skin located between the first elongate region and the edge of the skin; and shaping the skin by means of a mould which cooperate with the outer face of the skin, such that the first elongate region is a region of the skin with a change of direction, the treatment increasing the rigidity of the first elongate region at least after the shaping of the skin. 2. The method according to claim 1, wherein the step for applying a processing operation for increasing rigidity is carried out before the shaping step and comprises local application of a shape-maintaining material (24, 26) to the inner face of the skin. 3. The method according to claim 2, wherein the local application of a shape-maintaining material is the application of a thermoplastic resin (24). 4. The method according to claim 2, wherein the local application of a shape-maintaining material is the application of an adhesive (28) and a thermoplastic reinforcement (26). 5. The method according to claim 2, wherein the step which is intended to facilitate the shape maintenance comprises a cooling operation, after a heating step and the step for shaping on a mould. 6. The method according to claim 2, wherein the local application of a shape-maintaining material is the application of an aluminum strip which is adhesively bonded locally to the inner face of the leather skin. 7. The method according to claim 1, wherein the step for applying a processing operation for increasing rigidity is carried out after the step for shaping the skin, and comprises local compression (30) of the leather skin at said first elongate region remote from an edge of the skin. 8. The method according to claim 1, wherein the step for applying a processing operation for increasing rigidity is carried out after the step for shaping the skin, the method comprises local application of a shape-maintaining material (34) to the inner face of the skin, and the method comprises drying the shape-maintaining material (34) when the leather skin has the desired shape. 9. The method according to claim 1, wherein the step for applying a processing operation for increasing rigidity is carried out after the step for shaping the skin and comprises local application, to the inner face of the leather skin, of an impregnation material (32), then drying the impregnation material (32). 10. The method according to claim 1, further comprising a step for cutting the edge (20) in an inclined direction, in at least a portion of the leather skin between the first elongate region which is remote from an edge and that edge, so that the thickness of the skin progressively decreases towards the edge. 11. The method according to claim 3, wherein the step which is intended to facilitate the shape maintenance comprises a cooling operation, after a heating step and the step for shaping on a mould. 12. The method according to claim 4, wherein the step which is intended to facilitate the shape maintenance comprises a cooling operation, after a heating step and the step for shaping on a mould. 13. The method according to claim 2, further comprising a step for cutting the edge (20) in an inclined direction, in at least a portion of the leather skin between the first elongate region which is remote from an edge and that edge, so that the thickness of the skin progressively decreases towards the edge. 14. The method according to claim 1, wherein the method further comprises: facilitating the shape maintenance of the skin. 15. A method for manufacturing a trim component for an automotive vehicle, comprising: applying a treatment only locally to a first elongate region of the inner face of a leather skin, the first elongate region, being located remote from the edge of the skin and substantially parallel to the skin, without applying the treatment to the region of the skin located between the first elongate region and the edge of the skin; shaping the skin by means of a mould which cooperate with an outer face of the skin, such that a first elongate region is a region of the skin with a change of direction, the treatment increasing the rigidity of the first elongate region at least after the shaping of the skin; retaining the skin at the edge of a rigid support formed by a thermoplastic material; and a step of injecting a foam layer between the rigid support and the skin.
