Contoured fluid-filled chamber with tensile structures

摘要

A fluid-filled chamber, which may be incorporated into articles of footwear and other products, may include an outer barrier, a first tensile structure, and a second tensile structure. Any of the first and second tensile structures may include one or more textile tensile members. The first and second tensile structures may be located within an interior void defined by the outer barrier and may be bonded to the outer barrier. The first and second tensile structures may be bonded to the outer barrier in different areas of the outer barrier that are in fluid communication with each other. The first tensile structure may have a height greater than a height of the second tensile structure. In turn, the relative locations and differences of height between the tensile structures may impart a contour to the chamber.

主权项

1. An article of footwear incorporating a sole structure, the sole structure comprising:
a midsole that includes a fluid-filled chamber, the fluid-filled chamber comprising:
an outer barrier having an upper portion, an opposite lower portion, and a peripheral edge,a first tensile structure located within the outer barrier, anda second tensile structure located within the outer barrier; and an outsole secured to the midsole, the outsole forming at least part of a ground-contacting surface of the footwear;wherein (a) the first tensile structure has a first height at a first part near the second tensile structure, and the second tensile structure has a second height greater than the first height at a second part near the first tensile structure, and (b) an area of the chamber located between the first part and the second part is substantially free of interior bonds.
