A flame barrier made of nonwoven fabric for use as a component of a planar multilayer structure, especially a vehicle or aircraft passenger seat. The flame barrier contains staple fibers made of phenolic resin, para-aramid, or melamine resin, alone or mixed with 20 to 60 wt % preoxidized polyacrylonitrile staple fibers. The nonwoven fabric barrier also contains 15 to 30 wt % vermiculite, which is distributed through the entire volume of the nonwoven fabric. The flame barrier possesses a mass per unit area of 100 g/m.sup.2 to 210 g/m.sup.2. The method of manufacturing the nonwoven fabric flame barrier makes use of water jet needling.

In a process for manufacturing an interior fitted part for motor vehicles, such as an inside roof lining for automobiles, a staple-fiber formed fabric of a drawn polyethylene terephthalate matrix component and of a binding component is subjected at least once during the process to an annealing process, which increases the thermal stability of the fitted part. Also disclosed is a fitted part manufactured by this method.
