Abstract

A method for processing a textile sheet material includes sealing a sheet material in a sealing region. The sealing region comprising at least one partial region of the surface of the sheet material. The method also includes introducing a seam into the sheet material and cutting the sheet material along a cutting line. The textile sheet material may be used to produce covers for airbags used in vehicle seats.

Claims

1. A method for processing a textile sheet material comprising:

sealing a sheet material in a sealing region, the sealing region comprising at least one partial region of the surface of the sheet material;

introducing a seam into the sheet material; and

cutting the sheet material along a cutting line.

2. The method of claim 1, further comprising producing a cover from the textile sheet material.

3. The method of claim 2, further comprising producing a vehicle seat with the cover.

4. The method of claim 1, wherein the cutting line is provided in the sealing region.

5. The method of claim 1, wherein the step of introducing the seam comprises introducing the seam in the sealing region.

6. The method of claim 1, wherein the cutting line is provided essentially parallel to the seam.

7. The method of claim 1, wherein step of sealing the sheet material in the sealing region comprises utilizing an ultrasound treatment.

8. The method of claim 1, further comprising sewing the sheet material up together with other layers by means of the seam.

9. The method of claim 8, wherein the step of cutting the sheet material is carried out together with the step of sewing the sheet material up together with the other layers.

10. A textile sheet material comprising:

a seam,

a surface; and

at least one edge;

wherein the textile sheet material is processed by a method comprising (a) sealing the textile sheet material in a sealing region, the sealing region comprising at least one partial region of the surface of the sheet material;

(b) introducing the seam into the textile sheet material; and

(c) cutting the textile sheet material along a cutting line.

11. The sheet material of claim 10, wherein the textile sheet material is part of a cover for a vehicle seat.

12. The sheet material of claim 10, wherein the sealing region is provided adjacent to the at least one edge.

13. The sheet material of claim 10, wherein the seam is provided in the sealing region.

14. The sheet material of claim 10, wherein the at least one edge is provided essentially parallel to the seam.

15. The sheet material of claim 10, wherein the sealing region is provided in a predetermined width essentially parallel to the edge.

16. The sheet material of claim 10, wherein the textile sheet material is a stabilizing layer for an airbag.

17. The sheet material of claim 16, wherein the seam is at least partially provided as a predetermined breaking point.

18. The sheet material of claim 10, wherein the textile sheet material is a polyamide fabric.

19. A cover for a vehicle seat comprising:

a sheet material comprising a seam, a surface, and at least one edge;

wherein the sheet material comprises a sealing region comprising at least one partial region of the surface of the sheet material and a cutting line along which the textile sheet material is cut.

20. The cover of claim 19, wherein cover is utilized in a vehicle seat.

21. The cover of claim 19, wherein the sheet material comprises at least one decorative seam provided proximate the seam, the decorative seam being sewn in a single layer.

22. The cover of claim 19, wherein the sealing region is provided adjacent to the at least one edge.

23. The cover of claim 19, wherein the seam is provided in the sealing region and the at least one edge is provided essentially parallel to the seam.

24. The cover of claim 19, wherein the sheet material is a stabilizing layer for an airbag.

25. The cover of claim 19, wherein the seam is at least partially provided as a predetermined breaking point for an airbag.

26. A vehicle seat comprising:

a cover comprising a sheet material, the sheet material comprising a seam, a surface, and at least one edge;

wherein the sheet material comprises a sealing region comprising at least one partial region of the surface of the sheet material and a cutting line along which the textile sheet material is cut.

27. The vehicle seat of claim 26, wherein the sheet material comprises at least one decorative seam provided proximate the seam, the decorative seam being sewn in a single layer.

28. The vehicle seat of claim 26, wherein the sealing region is provided adjacent to the at least one edge.

29. The vehicle seat of claim 26, wherein the seam is provided in the sealing region.

30. The vehicle seat of claim 26, wherein the at least one edge is provided essentially parallel to the seam.

31. The vehicle seat of claim 26, wherein the sealing region is provided in a predetermined width essentially parallel to the edge.

32. The vehicle seat of claim 26, wherein the seam is at least partially provided as a predetermined breaking point.

33. The vehicle seat of claim 26, wherein the textile sheet material is a polyamide fabric.

34. The vehicle seat of claim 26, further comprising an airbag provided in the vehicle seat.

35. The vehicle seat of claim 34, wherein the sheet material is a stabilizing layer for the airbag.
