Abstract

The present invention relates to a belt strap for a safety belt device of a motor vehicle. The belt strap includes at least one cavity for receiving electronic components and/or lines. The cavity is formed by two fabric layers which are connected to one another in the outer edge sections by means of one or more weave thread/weave threads running parallel to the longitudinal direction of the belt strap.

First claim

The invention claimed is:

1. A belt strap for a safety belt device of a motor vehicle, comprising:
at least one cavity for receiving electronic components and/or lines,
wherein the cavity is formed by two fabric layers connected to one another in outer edge sections by one or more weave thread or threads running parallel to a longitudinal direction of the belt strap,
wherein the fabric layers are formed by a plurality of warp threads and weft threads, and the warp threads are connected to the weft threads in a 5/1/1-weave.

2. The belt strap according to claim 1 , wherein the belt strap has a width of 40 to 50 mm, and the outer edge sections in which the fabric layers are connected to one another by the weave threads each have a width of at least 2 mm.

3. The belt strap according to claim 1 , wherein the weave thread is woven in a 2/2-weave with the weft threads of the two fabric layers.

4. The belt strap according to claim 1 , wherein the two fabric layers are connected to one another in one or more connecting sections arranged between the edge sections to form two or more cavities separated from one another.

5. The belt strap according to claim 1 , wherein at least one electrical line and/or an electronic component is arranged in the cavity.

6. A belt strap for a safety belt device of a motor vehicle, comprising:
at least one cavity for receiving electronic components and/or lines,
wherein the at least one cavity is formed by two fabric layers connected to one another in outer edge sections by one or more weave thread or threads running parallel to a longitudinal direction of the belt strap, and
wherein the two fabric layers are connected to one another in one or more connecting sections arranged between the outer edge sections to form two or more cavities separated from one another.

7. The belt strap according to claim 6 , wherein the belt strap has a width of 40 to 50 mm, and the outer edge sections in which the fabric layers are connected to one another by the weave threads each have a width of at least 2 mm.

8. The belt strap according to claim 6 , wherein the fabric layers are formed by a plurality of warp threads and weft threads.

9. The belt strap according to claim 8 , wherein the weave thread is woven in a 2/2-weave with the weft threads of the two fabric layers.

10. The belt strap according to claim 8 , wherein the warp threads are connected to the weft threads in a 5/1/1-weave.

11. The belt strap according to claim 6 , wherein at least one electrical line and/or an electronic component is arranged in the cavity.
