Article with a cushioning assembly having inner and outer bladder elements with interfitting features and method of manufacturing an article

An article comprising:

• a cushioning assembly comprising:
• a first bladder element forming a first fluid chamber;
• a second bladder element within the first bladder element and forming a second fluid chamber sealed from and within the first fluid chamber;
• a third bladder element within the first bladder element and forming a third fluid chamber sealed from both the first fluid chamber and the second fluid chamber;
• wherein:
• the second fluid chamber has an inflation pressure above ambient pressure;
• the first bladder element comprises an inner surface;
• the second bladder element comprises an outer surface;
• the inner surface of the first bladder element interfits with the outer surface of the second bladder element such that a first area of the inner surface of the first bladder element is aligned with and bonded to a first area of the outer surface of the second bladder element at a bonded interface;
• the second bladder element comprises a deployable portion deployed laterally outward into contact with and bonded to a side portion of the inner surface of the first bladder element;
• the bonded interface includes the side portion of the inner surface of the first bladder element bonded to the deployable portion, and further includes opposing portions of the inner surface of the first bladder element at an upper side and a lower side of the second bladder element and adjacent to the side portion;
• the second bladder element is exposed to the first fluid chamber away from the bonded interface;
• the third fluid chamber has an inflation pressure above ambient pressure;
• the third bladder element comprises a deployable portion deployed laterally outward into contact with and bonded to an additional side portion of the inner surface of the first bladder element forming an additional bonded interface;
• the additional side portion is opposite from the side portion to which the deployable portion of the second bladder element is bonded;
• the first bladder element includes a first sheet bonded to a second sheet at a peripheral flange to enclose the first fluid chamber;
• the second bladder element comprises a flange forming a peripheral seam entirely displaced from the peripheral flange of the first bladder element and exposed to the first fluid chamber;
• the flange of the second bladder element surrounding the second bladder element and sealing the second fluid chamber;
• the peripheral seam of the second bladder element inclines within the first bladder element from the lower side of the second bladder element to the upper side of the second bladder element between the opposing portions of the inner surface of the first bladder element and toward the side portion to which the deployable portion of the second bladder element is bonded;
• the third bladder element comprises a flange forming a peripheral seam that surrounds the third bladder element and seals the third fluid chamber;
• and
• the peripheral seam of the third bladder element inclines within the first bladder element toward the additional side portion to which the deployable portion of the third bladder element is bonded.

An article of footwear comprising:

• a first bladder element including a first sheet bonded to a second sheet at a peripheral flange to enclose a first fluid chamber;
• a second bladder element and a third bladder element each disposed within the first fluid chamber and spaced apart from one another by a portion of the first fluid chamber;
• wherein the second bladder element and the third bladder element each include a deployable portion, the deployable portion of the second bladder element deployed laterally outward into contact with and bonded to a side portion of an inner surface of the first bladder element, the deployable portion of the third bladder element deployed laterally outward into contact with and bonded to a side portion of an inner surface of the first bladder element opposite to the side portion to which the second bladder element is bonded, and each of the second bladder element and the third bladder element further including an upper side and a lower side bonded to opposing portions of the inner surface of the first bladder element;
• and
• wherein the second bladder element and the third bladder element each include a peripheral seam displaced from the peripheral flange of the first bladder element, exposed to the first fluid chamber, and extending between the opposing portions of the inner surface of the first bladder element.
