Abstract

An insulating cover for a cushioning material for providing a barrier against heat and flame, the insulating cover comprising at least one layer of aluminum film or ceramic fabric, at least one layer of fire-blocking material, and at least one layer of adhesive, wherein the insulating cover is flexible so as to conform to and move with an underlying cushioning material. The insulating cover may be positioned between a cushion and the protective fabric of an aircraft passenger seat.

Claims

1. An insulating cover for a cushioning material for providing a barrier against heat and flame, comprising:

at least one layer selected from the group consisting of aluminum film and ceramic fabric;

at least one layer of fire-blocking material; and

at least one layer of adhesive;

wherein the at least one layer selected from the group consisting of aluminum film and ceramic fabric is arranged on the at least one layer of fire-blocking material to form an insulating layer;

wherein multiple insulating layers are secured together with the at least one layer of adhesive; and

wherein the insulating cover is flexible so as to conform to and move with an underlying cushioning material.

2. The insulating cover in accordance with claim 1, wherein the insulating cover is positioned between a cushioning material and a fabric covering.

3. The insulating cover in accordance with claim 1, wherein the ceramic fabric is selected from the group consisting of ceramic textiles, ceramic fibre yarns, ceramic fiber yarns reinforced with wire or glass filament and woven ceramic fabrics.

4. The insulating cover in accordance with claim 1, wherein the fire-blocking material is selected from the group consisting of fire retardant material, silicone foams of varying thickness, silicone applied to fiberglass and fire-blocking gels.

5. The insulating cover in accordance with claim 1, wherein the insulating cover covers a portion of the underlying cushioning material.

6. The insulating cover in accordance with claim 1, wherein the insulating cover covers substantially all of the underlying cushioning material.

7. A passenger seat, comprising:

a seat bottom portion supported by a frame and including a cushion and a fabric covering;

a seat back portion supported by the frame and including a cushion and a fabric covering; and

an insulating cover positioned between at least one of the seat bottom cushion and the fabric covering, and the seat back cushion and the fabric covering, the insulating cover comprising at least one layer selected from the group consisting of aluminum film and ceramic fabric, at least one layer of fire-blocking material, and at least one layer of adhesive;

wherein the at least one layer selected from the group consisting of aluminum film and ceramic fabric is arranged on the at least one layer of fire-blocking material to form an insulating layer;

wherein multiple insulating layers are secured together with the at least one layer of adhesive; and

wherein the insulating cover is flexible so as to conform to and move with the underlying cushion.

8. The passenger seat in accordance with claim 7, wherein the ceramic fabric is selected from the group consisting of ceramic textiles, ceramic fibre yarns, ceramic fiber yarns reinforced with wire or glass filament and woven ceramic fabrics.

9. The passenger seat in accordance with claim 7, wherein the fire-blocking material is selected from the group consisting of fire retardant material, silicone foams of varying thickness, silicone applied to fiberglass and fire-blocking gels.

10. The passenger seat in accordance with claim 7, wherein the insulating cover covers a portion of the underlying cushion.

11. The passenger seat in accordance with claim 7, wherein the insulating cover covers substantially all of the underlying cushion.
