Abstract

The present invention relates to a fabric ( 30, 31 ) with at least one support ( 41, 41′ ), with at least two electrical function elements ( 70 ), and with at least one seam ( 40 ).
It is provided that at least two of the electrical function elements ( 70 ) are in the form of strands and integrated in the seam ( 40 ).

First claim

The invention claimed is:

1. A method comprising:
providing at least one fabric including:
a) at least one support;
b) at least two electrical function elements; and
c) at least one seam;
wherein the at least two electrical function elements are in the form of strands and the at least two electrical function elements are integrated into the at least one seam,
wherein the method includes a step of operating at least one of the at least two electrical function elements, while at least one additional electrical function element is switched off.

2. The method according to claim 1 ,
wherein at least one of the at least two electrical function elements is an accompanying strand secured by the at least one seam; and
wherein the at least two electrical function elements are arranged on mutually different sides of the support.

3. The method of claim 2 , wherein the at least one seam comprises at least one seam thread.

4. The method of claim 2 , wherein the at least one seam comprises at least two seam threads.

5. The method of claim 4 , wherein the at least two seam threads are an upper seam thread and a lower seam thread and are primarily on mutually different surfaces of the support.

6. The method of claim 5 , wherein at least one of the at least two seam threads penetrate through the support one or more puncture sites.

7. A method comprising:
providing at least one fabric including:
a) at least one support;
b) at least two electrical function elements; and
c) at least one seam;
wherein the at least two electrical function elements are in the form of strands and the at least two electrical function elements are integrated into the at least one seam,
wherein the method includes a step of operating in a first operating state, one of the at least two electrical function elements that fulfills a first electrical function, and, in a second operating state, a second of the at least two electrical function elements fulfills a second electrical function which is physically different from the first function.

8. A fabric comprising;
a) at least one support;
b) at least two electrical function elements; and
c) at least one seam with at least two seam threads;
wherein the at least two electrical function elements are in the form of strands and the at least two electrical function elements are integrated into the at least one seam;
wherein at least one of the at least two electrical function elements is an accompanying strand secured by the at least one seam;
wherein the at least two electrical function elements are arranged on mutually different side of the support;
wherein the at least one seam comprises at least two seam threads, the at least two seam threads being an upper seam thread and a lower seam thread that are primarily on mutually different side of the fabric and penetrate through the support at one or more puncture sites;
wherein the one accompanying strands is now two accompanying strands that are a lower accompanying strand and an upper accompanying strand, wherein the upper accompanying strand and the lower accompanying strand are on mutually different sides of the fabric and do not penetrate into the support;
wherein the lower accompanying strand runs predominantly along the bottom side of the support and the upper accompanying strand runs predominantly along the top side of the support; and
wherein the upper accompanying strand and the lower accompanying strand are secured by:
i) the upper seam thread;
ii) the lower seam thread; or

iii) both the upper seam thread and the lower seam thread.

9. A heating device, wherein the heating device comprises at least one fabric according to claim 8 .

10. A sensor device, wherein the sensor device comprises at least one fabric according to claim 8 .

11. A steering device, wherein the steering device comprises at least one fabric according to claim 8 .

12. A vehicle seat, wherein the vehicle seat comprises at least one fabric according to claim 8 .

13. The fabric of claim 8 , wherein the upper seam thread and the lower seam thread contact, wind around, and hold one another.

14. The fabric of claim 8 , wherein one of the at least two electrical function elements is at least one of the following:
i) a heating strand;
ii) a contacting strand;
iii) an electrical fuse;
iv) a sensor conductor;
v) a shielding conductor; and
vi) a connecting conductor.

15. The fabric of claim 14 , wherein the upper accompanying strand on the top side of the support is a sensor conductor and the lower accompanying strand on the bottom side of the support is a heater so that the fabric is a heating device and a sensor device.

16. The fabric of claim 14 , wherein one of the at least two electrical function elements are integrated into at least one of the at least two seam threads.

17. The fabric of claim 16 , wherein the at least two electrical function elements are at least four electrical functional elements;
wherein the upper accompanying strand on the top side of the support is the heating strand and the upper seam thread is an electrical shielding conductor, and the lower accompanying strand is a sensor conductor and the lower seam thread is a contacting strand, forming a shielded person detector and a heating and sensing device.

18. A vehicle, wherein the vehicle comprises at least one fabric according to claim 8 .

19. The fabric of claim 16 , wherein an adhesive layer is attached to one side of the support.

20. The fabric of claim 19 , wherein at least one of the two seam threads penetrates through the adhesive layer.
