ABSTRACT:
A method for inflating a cushioning devices comprised of at least first and second distinct chambers having an interconnecting passage which provides fluid communication between the chambers. The method comprises either: (1) limiting the volume of at least one of the chambers, filling the chambers with a fluid at a single inflation pressure from a single inflation point and sealing the interconnecting passage, or (2) filling the chambers with a fluid at a single inflation pressure from a single inflation point compressing at least one of the distinct chambers, and sealing the interconnecting passage. The method is particularly suited to manufacture of a footwear cushion comprised of a body of elastomeric material having a plurality of sealed non-communicating cells having a single inflation point. At least two cells sharing a single sealed inflation passage are at different pressures.
