Abstract

Abstract A foam headliner for a vehicle is provided which comprises a wire mesh support sandwiched between two laminated layers of cross-linked ethylene or propylene homopolymer or copolymer foam, one layer being thicker than the other. A composite of a polyvinyl chloride homopolymer or copolymer foam and a decorative solid polyvinyl chloride homopolymer or copolymer film layer is laminated to the thick layer of cross-linked foam. The crosslinked foam is for energy absorption and the vinyl foam is to prevent the vinyl film from developing creases when the headliner is flexed during handling or installation. The wire mesh is for keeping the headliner from sagging between points of support. The wire mesh may be designed to be more flexible about one axis than the one transverse thereto to prevent deforming premolded areas of the headliner when handling or installing the headliner.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 33 words
The structure as recited in claim 1 wherein said cross-linked foam comprises a polymer selected from the group consisting of low density polyethylene, linear polyethylene, and stereoregular polypropylene and any of their copolymers.
Claim 2
Dependent Claim 15 words
The structure as recited in claim 1 wherein said cross-linked foam comprises low density polyethylene.
Claim 3
Dependent Claim 35 words
