Abstract

A map pocket usable as a trim component for a vehicle door assembly includes an inward-facing, substrate material layer including a polyethylene/polypropylene fibrous, thermoformed material and an outward-facing, A-side material layer including a non-woven, thermoformed material, disposed abuttingly against the substrate material layer.

First claim

What is claimed is:

1. A map pocket usable as a trim component for a vehicle door assembly, the map pocket comprising:
an inward-facing, substrate material layer comprising a polyethylene/polypropylene fibrous, thermoformed material, wherein the fibrous, thermoformed material comprises two material-types of fibers, polyethylene fibers and polypropylene fibers, that are neither woven nor knitted, but that are blended and laid into a matted form with the fibers randomly oriented in the mat; and
an outward-facing, A-side material layer comprising a non-woven, thermoformed material, disposed abuttingly against the substrate material layer.

2. The map pocket of claim 1 , wherein the map pocket has a shape and configuration that includes at least one substantially horizontal surface and at least one substantially vertical surface.

3. The map pocket of claim 2 , wherein the map pocket has a shape and configuration that includes at least one open end, and wherein objects are storable within the at least one open end against the at least one substantially horizontal surface and the at least one vertical surface.

4. The map pocket of claim 3 , further comprising a flange disposed about the at least one open end.

5. The map pocket of claim 4 , wherein the flange comprises a plurality of attachment point apertures for receiving a fastener.

6. The map pocket of claim 1 , wherein the A-side material layer comprises a Troubador material.

7. The map pocket of claim 1 , wherein the substrate material layer has a density of from about 500 grams per square meter to about 2000 grams per square meter.

8. The map pocket of claim 1 , wherein the substrate material layer has a thickness of about 3 to about 15 millimeters.

9. The map pocket of claim 1 , wherein the A-side material layer has a thickness of about 0.5 to about 5 millimeters.

10. The map pocket of claim 1 , wherein the substrate material layer excludes cut-out void portions, wherein a cut-out void portion is defined as a void within the periphery of the substrate layer that exceeds 5% of the total surface area of the substrate layer.

11. The map pocket of claim 1 , wherein the substrate material layer and the A-side material layer comprise a unitary, bi-layer, thermoformed structure.

12. The map pocket of claim 1 , wherein a ratio of polyethylene fibers to polypropylene fibers in the substrate material layer is from about 80:20 to about 20:80.

13. A vehicle comprising:
at least one door assembly, wherein the at least one door assembly comprises a plurality of trim components, wherein at least one of the plurality of trim components comprises a map pocket, and wherein the map pocket comprises:
an inward-facing, substrate material layer comprising a polyethylene/polypropylene fibrous, thermoformed material, wherein the fibrous, thermoformed material comprises two material-types of fibers, polyethylene fibers and polypropylene fibers, that are neither woven nor knitted, but that are blended and laid into a matted form with the fibers randomly oriented in the mat; and
an outward-facing, A-side material layer comprising a non-woven, thermoformed material, disposed abuttingly against the substrate material layer.

14. The vehicle of claim 13 , wherein the substrate material layer is disposed against the at least one door assembly and wherein the A-side material layer faces an interior portion of the vehicle.

15. The vehicle of claim 13 , wherein the map pocket is collapsible and serves as a barrier for protecting passengers of the vehicle against the forces of a side-impact collision.

16. The vehicle of claim 15 , wherein the substrate material layer is tunable to provide the vehicle with varying levels of side impact protection without any change to the shape or configuration of the map pocket.

17. A method for manufacturing a map pocket usable as a trim component for a vehicle, the method comprising the steps of:
providing or obtaining a substrate material layer comprising a polyethylene/polypropylene fibrous, thermoformable material, wherein the fibrous, thermoformed material comprises two material-types of fibers, polyethylene fibers and polypropylene fibers, that are neither woven nor knitted, but that are blended and laid into a matted form with the fibers randomly oriented in the mat;
providing or obtaining an A-side material layer comprising a non-woven, thermoformable material; and
disposing the substrate material layer adjacent to the A-side material layer in a thermoforming mold with adhesive between the A-side material layer and the substrate material layer, and thermoforming the substrate material layer with the A-side material layer to form the map pocket as a unitary, bi-layer structure.

18. The method of claim 17 , further comprising, subsequent to the step of thermoforming, performing post-processing steps comprising trimming the map pocket or forming attachment points in the map pocket.

19. The method of claim 17 , further comprising, subsequent to the step of thermoforming, attaching the map pocket to a vehicle door as a trim component of the vehicle door.

20. The method of claim 17 , wherein a ratio of polyethylene fibers to polypropylene fibers in the substrate material layer is from about 80:20 to about 20:80.
