Abstract
A back massager is powered through a control unit attached to a back cushion via a cable. The control unit has a jack coupled to a control circuit and through the cable to the cushion. Either an AC adapter or a 12 DC battery adapter may be plugged into the jack. Therefore, the same massager may be used in the home or an automobile (or the equivalent thereof). An air bladder may be pumped up or exhausted to control the firmness of the cushion.
