Abstract
An inflatable support pad wherein a first group of inflatable cells are in flow communication with each other, a second group of inflatable cells are in flow communication with each other, and the cells of the first group of cells are interleaved with the cells of the second group of cells whereby the cells are alternatively inflatable and alternately exhaustible. Seal seam portions or walls which separate adjacent cells have serpentine shapes and are disposed relative to each other to define alternately broad and narrow cell portions. The serpentine shapes are truncated to eliminate or reduce duck-billing.
