Abstract

A cargo management system including a vehicle load floor having a cellulose-based core to compartmentalize a cargo area of the vehicle into an upper compartment and a covered lower compartment is provided. The floor has a wood grain finish. The load floor includes a compression-molded composite panel that includes first and second outer layers of fiber-reinforced thermoplastic material, first and second sheets of thermoplastic adhesive and a core of cellulose-based material and positioned between the outer layers. The core has a cellular structure. The outer layers are bonded to the core by the first and second sheets and by press molding. The first outer layer having a top surface on which a multi-layer sheet is bonded by the press molding. The multi-layer sheet has a substantially planar upper support surface to support cargo in the upper compartment and to provide the load floor with the wood grain finish.

First claim

What is claimed is:

1. A cargo management system including a vehicle load floor to compartmentalize a cargo area of the vehicle into an upper compartment and a covered lower compartment, the floor having a wood grain finish, the system comprising:
a compression-molded composite panel including first and second outer layers of fiber-reinforced thermoplastic material, first and second sheets of thermoplastic adhesive, and a core of cellulose-based material and positioned between the outer layers and having a cellular structure, the outer layers being bonded to the core by the first and second sheets and by press molding, the first outer layer having a top surface; and
a multi-layer sheet bonded to the top surface of the first outer layer by the press molding and having a substantially planar upper support surface to support cargo in the upper compartment and to provide the load floor with the wood grain finish.

2. The system as claimed in claim 1 , wherein the load floor includes a cover part to cover the lower compartment, the cover part being movable between different use positions including open and closed positions relative to the rest of the load floor.

3. The system as claimed in claim 2 , wherein the cover part is pivotally connected to the rest of the load floor.

4. The system as claimed in claim 1 , wherein the multi-layer sheet includes a pattern layer which provides the wood grain finish.

5. The system as claimed in claim 4 , wherein the multi-layer sheet includes a substrate layer bonded to the lower surface of the pattern layer.

6. The system as claimed in claim 5 , wherein the multi-layer sheet includes a backing layer bonded to a lower surface of the substrate layer, the backing layer being bonded to the top surface of the first outer layer by the press molding.

7. The system as claimed in claim 1 , further comprising a plurality of parallel, spaced runners or rails which extend above a top surface of the multi-layer sheet to protect the top surface of the multi-layer sheet.

8. The system as claimed in claim 4 , wherein the pattern layer is a vinyl layer formed to simulate wood.

9. The system as claimed in claim 4 , wherein the pattern layer has a wood design on an upper surface thereof.

10. The system as claimed in claim 4 , wherein the pattern layer comprises a layer of natural wood.
