  • Publication number: 20090322118
    Abstract: A method of manufacturing a door for a vehicle may include forming an interior panel having a geometry including contours and vehicle accessories disposed thereon; forming a foam member having a varying thickness coinciding with the geometry of the interior panel, the foam member being resiliently compressible; retaining a moisture shield against the foam member; fixing the foam member to the exterior-facing side of the interior panel, the varied thickness of the foam member being aligned with the geometry of the exterior-facing side of the interior panel; and fixing the interior panel to the exterior door, the foam member resiliently biasing the moisture shield against an interior-facing side of the exterior door. The moisture shield, the foam member, and the interior panel form a pre-assembled module prior to fixing the interior panel to the exterior door.
