Flame protection fabric for vehicle seats, in particular for aircraft seats

1. A flame protection fabric for vehicle cushions wherein the flame protection fabric comprises the following layers:

at least one first abrasion-resistant layer as an abrasion layer comprising at least one textile material with abrasion resistance, and

at least one second layer as a barrier layer comprising at least one fibrous fleece of at least one flame-proof fiber type,

wherein said at least one abrasion layer is provided as a first layer on at least one side of said at least one barrier layer as a second layer,

wherein the at least one abrasion resistant layer consists of a fibrous fleece of 50 to 90% by weight of polyacrylonitrile (PAN) fibers and 10 to 50% by weight of para-aramide fibres applied over the entire surface of the at least one barrier layer and is not in the form of a grid or grid fabric, and

wherein the at least one barrier layer consists of at least one fibrous fleece of 50 to 90% by weight of acrylonitrile fibres, 5 to 30% by weight of para-amide fibres, and 5 to 30% by weight of pre-oxidized polyacrylonitrile (preox PAN) fibres.

2. The flame protection fabric of claim 1 , wherein at least one expanded graphite layer with a weight per unit area of between 30 and 110 g/m 2 is provided as an intermediate layer between the at least one abrasion layer and the at least one barrier layer.

3. The flame protection fabric according to claim 1 , wherein the at least one abrasion layer has a weight per unit area of between 100 and 180 g/m 2 .

4. The flame protection fabric according to claim 1 , wherein the at least one abrasion layer has an abrasion resistance of at least 30,000 cycles.

5. The flame protection fabric according to claim 1 , wherein the at least one barrier layer has a weight per unit area of between 50 and 150 g/m 2 .

6. The flame protection fabric according to claim 1 , further comprising at least one intumescent layer.

7. The flame protection fabric according to claim 6 , wherein at least one of the at least one intumescent layer includes expanded graphite, carbon or flame protection fibers.

8. The flame protection fabric according to claim 6 , wherein the at least one intumescent layer is provided as an intermediate layer between the at least one abrasion layer and the at least one barrier layer.

9. The flame protection fabric according to claim 6 , wherein the at least one intumescent layer has a weight per unit area of between 30 and 110 g/m 2 .

10. A cushion for a vehicle seat, comprising

at least one coating,

at least one flame protection fabric according to claim 1 ,

at least one foam part as padding.

11. The cushion according to claim 10 , wherein at least one of the at least one flame protection fabric is glued to the at least one foam part, and the flame protection fabric is laminated, coated, glued or sewn to at least one cover and is attached to the foam part by means of adhesive or fleece tapes.

12. The cushion according to claim 11 , wherein the at least one cover is fastened to the foam part with flame protection fabric by means of adhesive or fleece tapes.

13. A process for producing the flame protection fabric according to claim 1 comprising the steps of:

providing the at least one fibrous fleece of at least one flame-proof fiber type as the barrier layer, and

applying the at least one textile material with abrasion resistance as the abrasion layer of at least one fiber type to at least one side of the at least one fibrous fleece.

14. The process according to claim 13 , wherein the at least one textile material as the abrasion layer is coated with at least one intumescent layer on one side before applying to the at least one barrier layer.

15. The process according to claim 13 , wherein the abrasion layer, optionally intumescent layer and barrier layer are laminated, coated, glued or needled together.
