ABSTRACT:
A system supporting a cushion, containing a plurality of covered inflatable air bladders and the controls and means for inflating the bladders. Bladders may be arranged in two or more arrays and controlled so that each array is inflated and deflated at different times than are other arrays. This provides continuously variable pressure points for a cushion which supports a person. A re-programable microprocessor controls the sequence and timing of array inflation which can be selected to suit individual needs. An included rechargeable battery provides power for at least 16 hours operation and enables easy system portability. The system may be used in cushioning for wheelchairs, and for many other seating and support applications, including support for animals. It includes a remote control/alarm panel with an on/off switch and audio/visual alarms warning of power or other system failure. The system is simply constructed using mostly n0n-specialized components and materials, and is therefore relatively inexpensive.
