Abstract
Abstract An inflatable cushion is provided to be embedded in the upholstery of a motor vehicle seat. The cushion has one inflatable compartment and is typically placed near an exterior edge of a back support or seat cushion. As the inflatable cushion is inflated, the contours of the back support or seat cushion can be changed. The longitudinal interior edge of the cushion has a wave-like configuration which faces toward the central portion of the back support or seat cushion.
