ABSTRACT:
A back supporting and exercising cushion has upper and lower pneumatic chambers with an orifice or adjustable flow valve between the chambers for controlling shifting of air between the two chambers. With the back support device positioned in a chair or car seat, for example, the lower chamber is situated against the lumbar region of the back while the upper chamber presses against the mid-thoracic region. When the user shifts his posture, the chambers continually accommodate the changes by inflating one chamber while the pressure deflates air out of the other chamber. The ability to change posture frequently decreases fatigue in the low back while driving, for example, and provides neurological stimulation in the joints of the spine, which can help balance activities of the muscles in the back and decrease pain.
