Abstract
Abstract A muscle-relaxing therapeutic reclining chair including a framework and an inclined body-receiving cushioned portion comprising a plurality of chamber-defining portions carrying liquid under controllable pressure therein and which in one preferred form can be heated in a controlled manner and with the entire device being capable of being selectively and controllably oscillated by a vibrator means whereby to not only provide a soft fluid support equivalent to that provided by a water bed, but to provide the application of a desired amount of relaxing heat to a user's body while at the same time applying a desired amount of vibratory movement to the user's body whereby to be conducive toward complete muscle relaxation with all of the inherent therapeutic effects alleged to flow therefrom.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
186 words
A muscle-relaxing reclining chair comprising: a body-contoured, body-receiving, compressible cushion means provided with and carried by reclining chair framework means of substantially rigid construction, said body-receiving compressible effective cushion means taking the form of a plurality of compressible, hollow, sealed, inner chamber-defining portions arranged in substantially end-to-end, edge-contiguous relationship to each other; and means of interconnecting each of said hollow inner chamber portions to a source of fluid under pressure; a fluid supply source having a high-pressure output side connected to said interconnect means for supplying said fluid to said sealed inner chamber portions at a controlled pressure; a pressure control system including means of pressure sensing, pressure selection, and pressure adjustment in response to said selection, whereby the internal pressure of each said chamber may be set and regulated to a desired level; and means of electrically heating the fluid within each said inner chamber; a temperature control system including means of sensing the temperature of said fluid, selecting the desired temperatures, and adjustment of said electrical heating means whereby the fluid temperature within each chamber may be set and regulated to a desired level.
Claim 2
Dependent Claim
186 words
A muscle-relaxing reclining chair comprising: a body-contoured, body-receiving, compressible cushion means provided with and carried by reclining chair framework means of substantially rigid construction, said body-receiving compressible effective cushion means taking the form of a plurality of compressible, hollow, sealed, inner chamber-defining portions arranged in substantially end-to-end, edge-contiguous relationship to each other; and means of interconnecting each of said hollow inner chamber portions to a source of fluid under pressure; a fluid supply source having a high-pressure output side connected to said interconnect means for supplying said fluid to said sealed inner chamber portions at a controlled pressure; a pressure control system including means of pressure sensing, pressure selection, and pressure adjustment in response to said selection, whereby the internal pressure of each said chamber may be set and regulated to a desired level; and means of electrically heating the fluid within each said inner chamber; a temperature control system including means of sensing the temperature of said fluid, selecting the desired temperatures, and adjustment of said electrical heating means whereby the fluid temperature within each chamber may be set and regulated to a desired level.
Claim 3
Dependent Claim
66 words
A muscle-relaxing reclining chair as recited in claim 1, further comprising: means for individually imparting vibratory movement to each sealed fluid filled inner chamber; and a vibration control system including means of selection of the extent and magnitude of vibration and adjustment of said vibration means whereby the extent and magnitude of vibration of each said chamber may be set and regulated to a desired level.
