1. A method of producing a vehicle interior lining comprising:
- forming an intermediate product having a decorative layer and an open-cell foam barrier layer, the open-cell foam barrier layer adjoining a rear side of the decorative layer; and
providing a foam backing to a rear side of the intermediate product by a back foaming process that includes applying a liquid plastic to the open-cell foam barrier layer, wherein the open-cell foam barrier layer blocks the liquid plastic to prevent the liquid plastic from penetrating the open-cell foam barrier layer toward the decorative layer wherein the vehicle interior lining is permeable to air.

Abstract
A vehicle interior lining having good sound absorbing properties and that is permeable to air is formed from an intermediate product comprising an inside decorative layer and a barrier layer made of open-cell foam. The barrier layer adjoins the rear side of the decorative layer. A foam backing is disposed on the rear side of the intermediate product is provided with a foam backing. The barrier layer prevents the foam backing material from penetrating through toward the decorative layer, eliminating the need for a barrier film and improving sound absorption. The interior lining can be used as a roof lining.

14. A method of producing a vehicle interior lining comprising:
-
joining a decorative layer and a barrier layer together to form an intermediate product wherein the decorative layer comprises an air-permeable material and the barrier layer comprises an open-cell foam that is air-permeable; back foaming a foam layer onto one side of the intermediate product by applying a liquid plastic to the barrier layer; blocking the liquid plastic with the barrier layer to prevent the liquid plastic from penetrating the barrier layer and contacting the decorative; and wherein the barrier layer of the open-cell foam comprises a soft layer such that the intermediate product of the decorative layer and barrier layer cooperate to provide the vehicle interior lining with a soft touch exterior surface with the vehicle interior lining being permeable to air. - View Dependent Claims (15, 16, 17, 18, 19)
