Flexible fluid-filled chamber with tensile member
A method of making an article of footwear. The method may include forming a chamber for receiving a pressurized fluid, including a first chamber barrier layer, a second chamber barrier layer, and a tensile member extending between the first chamber barrier layer and the second chamber barrier layer. The tensile member may include a first tensile member layer, a second tensile member layer, and a plurality of tethers connecting the first tensile member layer to the second tensile member layer. The method may also include extending a portion of the second chamber barrier layer toward the first tensile member layer between a first section of the second tensile member layer and a second section of the second tensile member layer, and joining the portion of the second chamber barrier layer to the first tensile member layer between the first section and the second section of the second tensile member layer.
1. A method of forming a fluid-filled chamber, the method comprising:
positioning a first tensile member between a first barrier layer and a second barrier layer, the first tensile member including a first tensile member layer, a second tensile member layer having a first section and a second section separate from the first section, and a plurality of tethers connecting the first tensile member layer to the second tensile member layer;
bonding the first barrier layer to the second barrier layer to define an interior void between the first barrier layer and the second barrier layer;
extending a portion of the second barrier layer toward the first tensile member layer between the first section and the second section of the second tensile member layer; and
bonding the portion of the second barrier layer to the first tensile member layer.
2. The method of claim 1 , wherein bonding the first barrier layer to the second barrier layer includes forming a bonded region defining an outer periphery of the fluid-filled chamber.
3. The method of claim 2 , further comprising surrounding the first tensile member with the bonded region.
4. The method of claim 1 , further comprising attaching the first tensile member layer to the first barrier layer.
5. The method of claim 4 , further comprising attaching the second tensile member layer to the second barrier layer.
6. The method of claim 1 , wherein extending a portion of the second barrier layer toward the first tensile member layer forms an indentation in an outer surface of the fluid-filled chamber at the second barrier layer.
7. The method of claim 6 , further comprising tapering the indentation in a direction extending from the second tensile member layer toward the first tensile member layer.
8. The method of claim 1 , further comprising pressurizing the interior void.
9. The method of claim 1 , further comprising incorporating the fluid-filled chamber into a sole structure.
10. The method of claim 1 , further comprising incorporating the fluid-filled chamber into an article of footwear.
11. A method of forming a fluid-filled chamber, the method comprising:
positioning a first tensile member between a first barrier layer and a second barrier layer, the first tensile member including a first tensile member layer, a second tensile member layer defining a gap between a first section and a second section, and a plurality of tethers connecting the first tensile member layer to the second tensile member layer;
bonding the first barrier layer to the second barrier layer to define an interior void between the first barrier layer and the second barrier layer;
extending a portion of the second barrier layer toward the first tensile member layer between the first section and the second section of the second tensile member layer within the gap; and
bonding the portion of the second barrier layer to the first tensile member layer.
12. The method of claim 11 , wherein bonding the first barrier layer to the second barrier layer includes forming a bonded region defining an outer periphery of the fluid-filled chamber.
13. The method of claim 12 , further comprising surrounding the first tensile member with the bonded region.
14. The method of claim 11 , further comprising attaching the first tensile member layer to the first barrier layer.
15. The method of claim 14 , further comprising attaching the second tensile member layer to the second barrier layer.
16. The method of claim 11 , wherein extending a portion of the second barrier layer toward the first tensile member layer forms an indentation in an outer surface of the fluid-filled chamber at the second barrier layer.
17. The method of claim 16 , further comprising tapering the indentation in a direction extending from the second tensile member layer toward the first tensile member layer.
18. The method of claim 11 , further comprising pressurizing the interior void.
19. The method of claim 11 , further comprising incorporating the fluid-filled chamber into a sole structure.
20. The method of claim 11 , further comprising incorporating the fluid-filled chamber into an article of footwear.
