A trim element (1) includes a base element (2) of rigid plastic material, a supple skin (4), and a layer of foam (6), the trim element having a principle region (8) and a marginal region (10). The marginal region (10) includes an end region (16) in which the base element has a substantially constant
A trim element (1) includes a base element (2) of rigid plastic material, a supple skin (4), and a layer of foam (6), the trim element having a principle region (8) and a marginal region (10). The marginal region (10) includes an end region (16) in which the base element has a substantially constant thickness (e16) and the layer of foam is absent, and a coupling region (18) at a distance from the edge (12) of the base element (2) and the edge (14) of the skin (4 ) and in which the base element (2) has a thickness (e16) smaller than the thickness (e16) in the end region (16).

The invention claimed is: 1. Trim element comprising: a base element of rigid plastics material having an edge; a supple skin covering said base element and extending to said base element edge and having a substantially constant thickness; a layer of foam arranged between said base element and said skin; a principal region having a thickness; a marginal region having a thickness and extending to said base element edge, and said marginal region thickness being substantially constant and smaller than said thickness of the principal region; said marginal region having an end region extending to a periphery of said trim element at which said base element has a substantially constant thickness and said layer of foam is absent; and said marginal region having a coupling region located a distance from said base element edge at which said layer of foam extends between said base element and said skin, and the base element in said coupling region having a thickness smaller than in the end region. 2. The trim element according to claim 1, wherein said end region has portions of substantially constant width. 3. The trim element according to claim 2, wherein said end region has, locally, projections directed towards said principal region. 4. The trim element according to claim 3, wherein said projections extend as far as said principal region. 5. The trim element according to claim 1, wherein the coupling region extends over a majority of said marginal region. 6. The trim element according to claim 1, further comprising at least one ventilation duct located in said base element in said end region, between said coupling region and outside of said end region. 7. The trim element according to claim 6, wherein said at least one ventilation duct is at a site on said trim element at which said base element extends beyond said skin. 8. A method for manufacturing a trim element according to claim 1, comprising the following steps: forming a base element of rigid plastics material having an edge and having a marginal region which comprises an end region extending to the periphery of said marginal region and having a substantially constant thickness, and a coupling region extending a distance from said base element edge and having a thickness smaller than said end region thickness; forming a supple skin of substantially constant thickness; covering of said base element by said skin; arranging said skin and said base element in a cavity of a mould having a closure and a main body, in such a manner that, when said mould is closed, said closure and said main body are at a substantially constant distance from each other in said marginal region which comprises said end region and at least a portion of said coupling region; closing of said mould; applying said skin by pressure against said base element in said end region; and injecting foam between said base element and said skin. 9. The method according to claim 8, in which said base element comprises at least one ventilation duct located in said end region between said coupling region and outside of said end region, and said method further comprising: stopping of said injecting when foam escapes via the duct, beyond said skin. 10. The trim element according to claim 2, wherein said coupling region extends over a majority of said marginal region. 11. The trim element according to claim 3, wherein said coupling region extends over a majority of said marginal region. 12. The trim element according to claim 4, wherein said coupling region extends over a majority of said marginal region. 13. The trim element according to claim 2, further comprising at least one ventilation duct located in said base element in said end region between the coupling region and outside of said end region. 14. The trim element according to claim 3, further comprising at least one ventilation duct located in said base element in said end region, between said coupling region and outside of said end region. 15. The trim element according to claim 4, further comprising at least one ventilation duct located in said base element in said end region, between said coupling region and outside of said end region. 16. The trim element according to claim 5, further comprising at least one ventilation duct located in said base element in said end region, between said coupling region and outside of said end region.
