  • Publication number: 20050255306
    Abstract: In a method for producing a trim article (1), the interspace between a sheet-like decorative material (5) and a carrier (3) is foam-filled. There is provision, during foaming, for the decorative material (5) to be pressed sealingingly onto the interior-side surface of the carrier (3) so as to run around the region to be foam-filled. In this case, the discharge of the air to be displaced during foaming can take place through the foam-tight, but, at least in regions, not gas-tight structure of the carrier (3). For this purpose, the carrier (3) can be gas-sealed in regions by the local compression of an intrinsically gas-permeable unprocessed part before introduction into the foaming die. Also disclosed is a trim article capable of being produced according to the method.
