Article of footwear with a harness and fluid-filled chamber arrangement

An article of footwear, comprising:

• an upper;
• a sole structure secured to the upper;
• and
• an expansion-limited gas spring, comprising:
• at least one gas-filled chamber integrated with the sole structure;
• and
• an expansion-limiter disposed outside of the at least one gas-filled chamber and attached to the upper and the at least one gas-filled chamber, the expansion-limiter configured to mechanically limit expansion of the at least one gas-filled chamber in a downward direction away from the upper.

An article of footwear, comprising:

• an upper;
• a sole structure comprising a lateral side portion, an opposite medial side portion, a top portion proximate the upper, and an opposite bottom portion, the sole structure being secured to the upper;
• a compressible and expandable fluid-filled chamber integrated in a portion of the sole structure;
• and
• a structural harness attached to the upper, extending downward from the upper to the fluid-filled chamber, and being bonded to an outer portion of the fluid-filled chamber, the structural harness comprising:
• a first textile layer;
• a second textile layer generally parallel to and opposing the first textile layer;
• and
• a plurality of structural threads disposed between the first and second textile layers and bonded to the first and second textile layers, each of the plurality of structural threads transmitting tensile forces longitudinally and restricting stretch in a longitudinal direction of the thread,
• wherein portions of the structural threads extending downward from the upper to the outer portion of the fluid-filled chamber are in a generally tensile configuration and transmit forces to bias the fluid-filled chamber in an upward direction toward a top region of the sole structure proximate the upper.
