ABSTRACT:
This hydro-massage chair comprises horizontally-spaced sidewalls, a seat portion extending between the sidewalls, and an inclined back portion adapted to support the back of a patient seated on the seat portion. An inflatable hollow cushion has a back wall bearing against the inclined back portion and a soft front wall facing the back of the seated patient. The cushion is inflated by introducing liquid into its interior. Nozzles are mounted in spaced relation along the length of the cushion for injecting pressurized liquid jets into the interior of the cushion and against the inside of the front wall of the cushion to produce a massaging effect on the back of the seated patient. A plurality of bars spaced apart along the length of the cushion extend between the sidewalls and confine the front wall of the inflated cushion but allow the front wall to bulge slightly in the regions between the bars when the cushion is inflated with liquid.
