ABSTRACT:
An automotive headliner assembly includes a substrate that is configured to mount to a vehicle in a position generally covering a lower surface of a passenger compartment roof. Cavities are formed into the substrate between the upper substrate surface and the lower substrate surface to provide receptacles for electrical wiring, fiber optic cabling, EA foam and the like or to form a duct for directing air flow. Each of the cavities is integrally formed in the substrate. A foam layer is adhered to a lower surface of the substrate and the decorative cover is adhered to a lower surface of the foam layer. The headliner is constructed by first extruding molten parison into a blow mold shaped to complement the desired exterior contours of the headliner substrate to be formed. The cavities are then formed in the molten parison by inserting at least one blow pin into the parison and injecting pressurized gas. For those cavities that are configured to hold energy-absorbing foam, foam is provided within each such cavity by inserting a nozzle into the cavities and filling the cavities with the foam.
