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.

Contoured fluid-filled chamber with tensile structures

A spacer textile material may include a first layer, a second layer, and a plurality of connecting members extending between and joining the first layer and the second layer. The connecting members may form a series of at least ten rows that are separated by spaces. The rows have a width that is less than a width of the spaces, and the connecting members form at least one stabilizing row with a width that is greater than the width of the spaces.

Spacer textile materials and methods for manufacturing the spacer textile materials

A fluid-filled chamber, which may be incorporated into articles of footwear and other products, may include an outer barrier and a tensile member. The outer barrier may have an upper portion, an opposite lower portion, and a peripheral edge. The upper portion and lower portion may be bonded together in a bonded region spaced inward from the peripheral edge. The bonded region may have a convex shape. The tensile member may be located within the outer barrier, and may be formed to have at least one gap. The bonded region may extend at least partially into the gap.

Fluid-filled chamber with a tensile member

In one method of manufacturing a fluid-filled chamber, two polymer layers are located between two mold portions, the surfaces of the mold portions cooperatively defining a peripheral cavity with first and second regions, an inward extent of the first region exceeding an inward extent of the second region. A tensile structure may be positioned between the polymer layers and the mold portions may be compressed together. Part of a peripheral portion of the chamber may be formed by drawing first and second areas of the chamber against the first and second regions of the peripheral cavity, respectively. After pressurization, the first region of the peripheral cavity may have a greater extent of outward protrusion than the second region of the peripheral cavity. Accordingly, an asymmetric medio-lateral shape may be imparted to the chamber without the use of a tensile structure that is itself tapered or contoured.

Method of manufacturing a contoured fluid-filled chamber with tensile structures

A method for manufacturing a fluid-filled chamber may include obtaining a spacer textile material a stabilization structure. A tensile member is removed from an area of the spacer textile material where the stabilizing structure is absent. The tensile member is located between a first polymer element and a second polymer element. Additionally, (a) the first layer is bonded to the first polymer element, (b) the second layer is bonded to the second polymer element, and (c) the first polymer element and the second polymer element are bonded together around a periphery of the tensile member.
