Abstract
A fluid-filled chamber may include an upper barrier portion, a lower barrier portion, and a tensile member. An upper tensile layer of the tensile member may be secured to the upper barrier portion, and a lower tensile layer of the tensile member may be secured to the lower barrier portion. The upper barrier portion and the lower barrier portion may have first areas and second areas. The first areas may be indentations extending into the chamber, and the second areas may be protrusions extending outward from the chamber. At least a portion of the first areas may be unbonded with the upper barrier portion and the lower barrier portion. Accordingly, one or more properties of the chamber, such as a flexibility, stiffness, rigidity, tensile response, compressibility, or force attenuation property, may be altered.
