Embodiment Construction

[0032] refer to figure 1 and figure 2 , describes a vehicle trim element 1 comprising at least a support layer 2 , a decorative layer 4 and a functional layer 6 . Such trim elements are intended, for example, to form door panels, dashboard covers or center console covers or the like.

[0033] The support layer 2 is arranged to impart its shape and mechanical properties, in particular its stiffness, to the decorative element 1 . Thus, the support layer 2 is eg made of a substantially rigid material for a door panel, eg plastic or composite material. According to one embodiment, the support layer 2 is made of a composite material (also known under the English name NFPP for "Natural Fiber Polypropylene") comprising natural fibers in a polypropylene matrix. Natural fibers are selected, for example, from flax, hemp, kenaf and / or wood. The support layer 2 is formed, for example, by hot pressing in a pressing tool having the desired shape of the support layer 2 corresponding to ...

Abstract

The invention provides a decorative element comprising a heating element made of a carbon material, comprising at least one support layer (2) having an inner surface (8) and an outer surface (10) and at least one functional layer (6) made of a carbon material and extending over at least a portion of the inner surface (8) of the support layer (2) or over at least a portion of the outer surface (10) of the support layer (2). At least a portion of the functional layer (6) defines at least one heating element formed by a pattern (18), the pattern (18) comprising at least one electrically conductive region (20) made of a carbon material and at least one non-electrically conductive region (22) formed by vias in the functional layer (6), the electrically conductive region (20) being powered by a current source electrically connected to the electrically conductive region (20).

Description

technical field [0001] The invention relates to a decorative element of the type comprising at least one support layer comprising an inner surface and an outer surface and at least one functional layer, the functional layer being made of carbon material and at least one of the inner surfaces of the support layer extending over a portion or over at least a portion of the outer surface of the support layer. [0002] The invention also relates to a manufacturing method for such a decorative element. [0003] The invention is applied, for example, to decorative elements forming door panels, center console coverings or instrument panel coverings or the like of a vehicle. Background technique [0004] In order to lighten such decorative elements and reduce their impact on the environment, it is known to make the support layer of the decorative element from a composite material comprising, for example, natural fibers embedded in a matrix made of plastic material. [0005] Further...
