Patent

CA 2370822

A headliner for the interior of the vehicle, such as an automobile, includes a porous polyurethane substrate (102) having an A-side surface and a B-side surface. The B-side surface is united with reinforcing layer. The A-side surface is concealed with a decorative cloth (106), optionally having a foamed backing (108), exposed to the interior of the vehicle. Interposed between the A-side surface and the decorative cloth is a multi-layered laminate (120), which includes an adhesive layer (122) for adhering the multi-layered laminate to the decorative cloth, a barrier layer (124) for preventing the polyurethane or polyurethane precursors from bleeding therethrough during formation of the substrate; and a shape-retaining layer (126) having sufficient strength to prevent the pores in the A-side surface of the substrate from substantially influencing the outer appearance of the decorative cloth.

L'invention concerne une garniture de pavillon pour l'intérieur d'un véhicule, tel qu'une voiture, comprenant un substrat poreux (102) en polyuréthane pourvu d'une surface A et d'une surface B. La surface B est unie à l'aide d'une couche de renfort. La surface A est dissimulée par un tissu décoratif (106), pouvant comporter une sous-couche mousse (108), exposé vers l'intérieur du véhicule. Un stratifié multicouche (120), intercalé entre la surface A et le tissu décoratif, comprend une couche adhésive (122) permettant audit stratifié d'adhérer au tissu décoratif, une couche barrière (124) destinée à empêcher le polyuréthane ou ses précurseurs de couler au cours de la formation du substrat, ainsi qu'une couche de maintien de la forme (126), dotée d'une résistance suffisante pour empêcher les pores de la surface A du substrat d'influencer l'aspect extérieur du tissu décoratif.
