Fluid-Filled Chamber With Stitched Tensile Member

摘要

A chamber for receiving a pressurized fluid may include a tensile member extending between a first chamber barrier layer and a second chamber barrier layer and including a plurality of tethers extending between the first tensile member layer and the second tensile member layer. The chamber may include stitching through the tensile member in a stitched region. When the chamber is pressurized with the pressurized fluid, a substantial majority of the first tensile member layer is separated from the second tensile member layer by a distance that corresponds to a length of the plurality of tethers. In addition, the first tensile member layer is held in contact with the second tensile member layer by the stitching in the stitched region, thereby forming an area of the chamber having a reduced thickness relative to adjacent portions of the chamber.

1. A chamber for receiving a pressurized fluid, comprising:
a first chamber barrier layer and a second chamber barrier layer bonded to the first chamber barrier layer about peripheral portions of the first chamber barrier layer and the second chamber barrier layer to define an interior void between the first chamber barrier layer and the second chamber barrier layer; a tensile member extending between the first chamber barrier layer and the second chamber barrier layer, the tensile member including a first tensile member layer bonded to the first chamber barrier layer, a second tensile member layer bonded to the second chamber barrier layer, and a plurality of tethers extending between the first tensile member layer and the second tensile member layer; and stitching through the tensile member in a stitched region; wherein, when the chamber is pressurized with the pressurized fluid, a substantial majority of the first tensile member layer is separated from the second tensile member layer by a distance that corresponds to a length of the plurality of tethers; and wherein the first tensile member layer is held in contact with the second tensile member layer by the stitching in the stitched region, thereby forming an area of the chamber having a reduced thickness relative to adjacent portions of the chamber.
