Abstract
An integral sound absorber and water deflector door panel positionable in space defined between an inner wall and a passenger compartment door panel of an automobile vehicle door assembly. The integral panel is composed of a first polymeric layer made of a water impervious polymeric film having an essentially constant thickness. The first polymeric layer has a first face adapted to contact the interiorly oriented face on the inner wall of the vehicle door assembly and remain in overlying parallel orientation thereto. A second polymeric layer is composed of a polymeric foam integrally connected to the second face of the first polymeric layer in continuous overlying relationship thereto. The second polymeric layer has an outer face opposed to the first polymeric layer which, preferably, has at least one region adapted to directly contact a portion of the exteriorly oriented face of the passenger compartment door panel. The thickness of the first polymeric layer of the integral door panel is essentially uniform throughout the part while the thickness of the second polymeric layer varies positionally to conform the dimensional requirements of the surrounding door assembly and particula…
