Abstract

A method for manufacturing a vehicular door assembly (10) having a door (12), a door panel (14), a substrate (54), a plurality of systems, and a plurality of components. The method includes the steps of fastening the door panel (14) to the door (12), attaching the substrate (54) to the door panel (14), and securing the plurality of components to the substrate prior to attaching the substrate to the door panel (14) such that each of the plurality of components is operational upon the substrate being attached to the door panel (14).

Claims

1. A method for manufacturing a vehicular door assembly, the method comprising the steps of:

attaching a door panel made entirely of a polymer-based, recyclable material to an inner surface of a door to cover at least a portion of the door such that the door panel is visible to an occupant;

securing at least one component capable of actuating at least one system of the vehicular door assembly to a substrate to form a modular unit; and

attaching the modular unit to the door panel after said securing step such that the substrate is visible to the occupant,

whereby the door panel is in a recyclable condition by removing the modular unit front the door panel and removing the door panel from the door without additional disassembly of the door panel.

2. A method as set forth in claim 1 including the step of connecting at least a portion of the at least one component to the at least one system associated therewith before the step of attaching the substrate to the door panel.

3. A method as set forth in claim 2 wherein the step of securing the at least one component includes the step of aligning a portion of the at least one component such that the at least one component is connected to the at least one system associated therewith during the step of attaching the substrate to the door panel.

4. A method as set forth in claim 3 including the step of forming the substrate with a recessed cavity to receive the at least one component therein.

5. A method as set forth in claim 4 including the step of forming the substrate from polypropylene.

6. A method as set forth in claim 5 including the step of forming the door panel from polypropylene.

7. A method as set forth in claim 6 including the step of removing the substrate from the door panel and removing the door panel from the door to facilitate re-manufacturing the door panel for post-consumer use.

8. A method as set forth in claim 7 including the step of removing the at least one component from the vehicular door assembly when removing the substrate from the door panel.

9. A method as set forth in claim 1 wherein the door panel includes an upper door panel and a lower door panel and further including the step of attaching the upper panel to the lower panel.

10. A method as set forth in claim 9 including the step of attaching the substrate to one of the upper and lower door panels.
