Abstract

See full text

An adaptive cushion for reducing pressure on body parts of a person positioned on a chair or bed includes an overlay cushion having a plurality of individual air bladder cells, each having thereon a force sensor. The cushion includes a controller for inflating and deflating individual air bladder cells to air pressures that tend to reduce the interface pressures sensed by the force sensors. A pressure reduction method includes varying the inflation pressure in a first air bladder cell while measuring the sum of the interface pressures exerted on all or a plurality of the air bladder cells, re-pressurizing the first cell to that air pressure for which a minimum total interface pressure was obtained, repeating this process for the remaining air bladder cells.
