Abstract

Disclosed is a woven strap, particularly for safety belts in motor vehicles, which is characterized in that said woven strap comprises a first group of warp threads and a second group of warp threads, the warp threads of the first group being provided with a greater elongation than the warp threads of the second group.

Claims

1. A method of manufacturing a webbing from threads, the method comprising weaving a first warp group of the threads and a second warp group of the threads, one of the warp groups being more extensible than the other of the warp groups, at least one of the threads being electrically conductive.

2. The method as set forth in claim 1, further comprising concealing the at least one conductive thread in an interior of the webbing.

3. The method as set forth in claim 1, further comprising varnishing a surface of the at least one conductive thread.

4. The method as set forth in claim 1, further comprising winding the at least one conductive thread around one of the warp threads.

5. The method as set forth in claim 1, further comprising making a seat belt from the threads.

6. A woven webbing, particularly for automotive seat belts, the webbing comprising a first group of warp threads and a second group of warp threads, the warp threads of the first group having a higher extensibility than the warp threads of the second group.

7. The webbing as set forth in claim 6, further comprising warp threads of a third group are included therein which comprise electrical conductors.

8. The webbing as set forth in claim 6, wherein the warp threads of the first group comprise electrical conductors.

9. The webbing as set forth in claim 8, wherein the electrical conductors are each electrically insulated on their surface.

10. The webbing as set forth in claim 9, wherein the electrical conductors are each varnished on their surface.

11. The webbing as set forth in claim 10, wherein the electrical conductors are each wound around the warp threads.

12. The webbing as set forth in claim 11, further comprising a pitch S of the windings is set to a predefined value.

13. The webbing as set forth in claim 10, further comprising finely curled wire arranged as the electrical conductors within the warp threads to form a staple common fiber.

14. The webbing as set forth in claim 6, wherein the warp threads comprise electrical conductors concealed in the interior of the webbing.

15. The webbing as set forth in claim 6, further comprising one or more electrical device(s), essentially taken from the group of:

microphone(s), sensor(s), and controller(s), is/are applied to one or more locations in the region of the warp threads of the first group.

16. A seat belt comprising:

first warp threads;

second warp threads having a different characteristic than the first warp threads; and

an elongated conductive member;

the first warp threads and second warp threads being woven together in a webbing, and the conductive member being coupled to the webbing.

17. The seat belt as set forth in claim 16, further comprising an electronic controller connected to the conductive member and at least one of the warp threads.

18. The seat belt as set forth in claim 16, further comprising a microphone connected to the conductive member and at least one of the warp threads.

19. The seat belt as set forth in claim 16, wherein the conductive member is concealed within the woven warp threads.

20. The seat belt as set forth in claim 16, wherein the conductive member is wound around one of the warp threads.
