Abstract: A process for assembling a composite piece for use in the interior of an automobile. An outward facing skin of the composite piece is connected to a substrate by a foaming material, and at least one switch item is integrated seamlessly into the composite piece. Part of the process includes wrapping a visible portion of each switch item with the outward facing skin. A spare piece is placed against the surface of the visible area of each item opposite the surface located on the visible surface of the composite piece. A foaming material is injected between the skin and the substrate, and then each spare piece is removed. A control component is placed at each cavity left where the removed spare pieces blocked expansion of the foaming material.

Abstract: An interior trim element provided with a display device and a method for producing such an element is disclosed. The interior trim element includes a substrate, an intermediate layer of foam material and a covering skin. It integrates the display device by means of backlighting a facing, the projection of which is shown on a display area of the covering skin. The interior trim element further includes a light box of the display device at least partly fitted into a corresponding receiving mount arranged in the substrate and the layer of intermediate material and extending up to the internal surface of the relevant display area of the skin, and in that a sheet of semi-rigid material is attached, directly or with the interposition of the facing, onto the internal face of the display area.
