CONTOURED FLUID-FILLED CHAMBER

摘要

A fluid-filled chamber (40) may be incorporated into footwear and other products. The chamber is formed from a polymer material that defines a first surface (41), a second surface (42) located opposite the first surface, and a sidewall surface (43) extending around a periphery of the chamber and between the first surface and the second surface. A plurality of bonds (45) are spaced inward from the sidewall surface and join the first surface and the second surface, and the bonds are distributed to form a regularly-spaced array, such as a hexagonal array. In some configurations, the first surface and the second surface may define elliptically-shaped structures between the bonds. In addition, the bonds may be formed to have a slope that is an average of slopes of the first surface and the second surface in areas proximal the bonds.
