Abstract

A vandal resistant upholstered seat or seat insert comprises a substrate formed of a hard material such as plastic, fiberglass, steel or the like; a vertical pile fabric having a non-coated backing covering the outer surface of the seat insert, with the vertical pile fabric including a plurality of generally upright fibers embedded in a backing material, with the fibers and the backing material being formed such that the backing and vertical fibers are accessible to a liquid adhesive applied to the underside of the backing material; and a layer of high-strength adhesive permeating the backing material from the underside and bonding securely the backing material and upright fibers to the substrate, the adhesive providing a fabric to substrate bond that exceeds the tensile strength of the fabric itself or has a peeling strength of at least twenty-five (25) pounds per inch width of fabric.

Claims

1. A vandal resistant upholstered seat insert for a seat wherein the seat insert is shaped to fit in a seat insert portion of the seat and wherein the seat insert is attached to the seat by releasable fastening means, the seat insert comprising:

a hard substrate shaped to fit in the seat insert portion of the seat and including means for removably attaching the seat insert to the seat by means of the insert fastening means, the substrate having an outer surface that is engaged by a seated passenger;

a vertical pile fabric covering the outer surface of the substrate comprising a planar backing material with a plurality of generally upright fibers attached to the backing material and extending outwardly from an outer side of the backing material; and

a layer of high strength adhesive interposed between the vertical pile fabric and the substrate and affixing the vertical pile fabric to the substrate, the adhesive bonding the fabric to the substrate with a bond strength that is sufficient to resist peeling of the fabric from the substrate.

2. A vandal resistant upholstered seat insert for a seat comprising:

a hard substrate that is attachable to the seat, the substrate having an outer surface that is engaged by a seated passenger;

a vertical pile fabric covering the outer surface of the substrate comprising a planar backing material with a plurality of generally upright fibers attached to the backing material and extending outwardly from an outer side of the backing material; and

a layer of high strength adhesive interposed between the vertical pile fabric and the substrate and affixing the vertical pile fabric to the substrate, the adhesive bonding the fabric to the substrate with a bond strength that is sufficient to resist peeling of the fabric from the substrate, the adhesive bonding the fabric to the substrate with a peel strength that either exceeds the tensile strength of the fabric or is at least about twenty-five (25) pounds per inch width of fabric.

3. A vandal resistant upholstered seat insert for a seat comprising:

a hard substrate that is attachable to the seat, the substrate having an outer surface that is engaged by a seated passenger;

a vertical pile fabric covering the outer surface of the substrate comprising a planar backing material with a plurality of generally upright fibers attached to the backing material and extending outwardly from an outer side of the backing material; and

a layer of high strength adhesive interposed between the vertical pile fabric and the substrate and affixing the vertical pile fabric to the substrate, the adhesive bonding the fabric to the substrate with a bond strength that is sufficient to resist peeling of the fabric from the substrate, the backing comprising an uncoated permeable fibrous material exposed to the adhesive on the underside of the backing, the adhesive penetrating the fibrous material from the inner side thereof, bonding the fibrous material completely to the substrate, the penetration of the adhesive being substantially limited to the backing, such that the adhesive does not extend outwardly into the pile fibers to the point where the adhesive is visible or adversely affects the feel of the pile fabric.

4. A vandal resistant upholstered seat insert according to claim 3, wherein the pile fibers are looped through the backing, with looped ends engaging the backing and being exposed to adhesive contact from the inner side of the backing, such that the adhesive bonds the pile fibers and the back together and to the substrate.

5. A vandal resistant upholstered seat insert according to claim 4, wherein the adhesive is resistant to solvents including water, alcohol, and aromatic and aliphatic hydrocarbons, and is heat resistant up to at least 400°

F.

6. A vandal resistant upholstered seat according to claim 3, wherein the substrate and adhesive both are formed of polyester resin materials so as to maximize bonding of the adhesive to the substrate.

7. A vandal resistant upholstered seat insert for a seat comprising:

a hard substrate that is attachable to the seat, the substrate having an outer surface that is engaged by a seated passenger;

a vertical pile fabric covering the outer surface of the substrate comprising a planar backing material with a plurality of generally upright fibers attached to the backing material and extending outwardly from an outer side of the backing material; and

a layer of high strength adhesive interposed between the vertical pile fabric and the substrate and affixing the vertical pile fabric to the substrate, the adhesive bonding the fabric to the substrate with a bond strength that is sufficient to resist peeling of the fabric from the substrate,

the backing material being a woven or non-woven fibrous material and the pile fibers being individual fibers or yarns that are looped through the backing material and cut in a U-shaped, V-shaped, or W-shaped configuration, the underside of the backing being permeable by the adhesive and the adhesive permeating just the backing without bleeding into the pile fibers to the point where the adhesive adversely effects the appearance or texture of the pile.

8. A vandal resistant upholstered seat insert for a seat comprising:

a hard substrate that is attachable to the seat, the substrate having an outer surface that is engaged by a seated passenger;

a vertical pile fabric covering the outer surface of the substrate comprising a planar backing material with a plurality of generally upright fibers attached to the backing material and extending outwardly from an outer side of the backing material, the backing material being a woven or non-woven fibrous material and the pile fibers are individual fibers or yarns that are looped through the backing material and cut in a U-shaped, V-shaped, or W-shaped configuration, the pile fiber length being at least about one-sixteenth (1/16) inches; and

a layer of high strength adhesive interposed between the vertical pile fabric and the substrate and affixing the vertical pile fabric to the substrate, the adhesive bonding the fabric to the substrate with a bond strength that is sufficient to resist peeling of the fabric from the substrate, the underside of the backing being permeable by the adhesive and the adhesive permeating just the backing without bleeding into the pile fibers to the point where the adhesive adversely affects the appearance or texture of the pile.

9. A vandal resistant upholstered seat insert according to claim 8, wherein the maximum pile fiber length is about three-eighths (3/8) inches.

10. A vandal resistant upholstered seat insert according to claim 9, wherein the pile fiber length is about five thirty-seconds (5/32) inches.

11. A vandal resistant upholstered seat comprising:

a hard substrate having an outer surface that is engaged by a seated passenger;

a vertical pile fabric covering at least a portion of the outer surface of the substrate, the vertical pile fabric comprising a planar backing material with a plurality of generally upright fibers attached to the backing material and extending outwardly from an outer side of the backing material; and

a layer of high strength adhesive interposed between the vertical pile fabric and the substrate and affixing the vertical pile fabric to the substrate, the adhesive bonding the fabric to the substrate with a bond strength that is sufficient to effectively restrain the fabric from being peeled from the substrate.

12. A vandal resistant upholstered seat according to claim 11, wherein the adhesive bonds the fabric to the substrate with a peeling strength that either exceeds the tensile strength of the fabric or is at least about twenty-five (25) pounds per inch width of fabric.

13. A vandal resistant upholstered seat according to claim 11, wherein the backing comprises an uncoated permeable fibrous material exposed to the adhesive on the underside of the backing, the adhesive penetrating the fibrous material and bonding the fibrous material to the substrate, the penetration of the adhesive being substantially limited to the backing, such that the adhesive does not extend outwardly into the pile fibers to the point where the adhesive is visible or adversely affects the feel of the pile fabric.
