Abstract

A massage chair includes a base frame; a cradle in which a person sits, the cradle being rotatably mounted to the base frame on a cradle bearing structure and pivoting at a cradle axis, the cradle including a vibration generation mechanism mounted within the cradle for producing and delivering vibration into the body of a person seated in the cradle; and a having cradle pivot mechanism connected to the cradle for pivoting the cradle relative to the base frame to a sitting position in which the center of gravity of a person seated in the cradle is substantially over the cradle axis to evenly distribute the weight of a person seated in the cradle over the cradle, and for pivoting the cradle to at least one reclining position.

Claims

1. A massage chair, comprising:

a base frame;

a cradle in which a person sits, said cradle being rotatably mounted to said base frame on cradle bearing means and pivoting at a cradle axis, said cradle comprising vibration generation means mounted within said cradle for producing and delivering vibration into the body of a seated person;

and having cradle pivot means connected to said cradle for pivoting said cradle relative to said base frame to a sitting position in which the center of gravity of a seated person is substantially over the cradle axis to evenly distribute the weight of a seated person over said cradle, and for pivoting said cradle to at least one reclining position.

2. The massage chair of claim 1, wherein said cradle pivot means additionally pivots said cradle forwardly to a cradle entry and exit position.

3. The massage chair of claim 1, wherein said cradle comprises a cradle frame having a cradle perimeter member and cradle frame cross members extending across and secured to said cradle perimeter member, said cradle frame being curved to conform to the shape of a human back.

4. The massage chair of claim 3, wherein said cradle additionally comprises cradle padding fitted to and substantially covering said cradle frame.

5. The massage chair of claim 1, additionally comprising a heating element secured within said cradle for delivering heat into the back of a seated person.

6. The massage chair of claim 5, wherein said cradle comprises two arm structures, said arm structures being fastened to opposing sides of said cradle.

7. The massage chair of claim 6, wherein said cradle bearing means comprises an axle bore in each said arm structure, and axle means extending from said base frame and passing into said axle bores.

8. The massage chair of claim 1, wherein said base frame comprises two laterally spaced apart side structures interconnected by a plurality of base frame cross members extending between and interconnecting said side structures, and a base frame middle member substantially midway between said side structures and extending across and secured to said base frame cross members.

9. The massage chair of claim 8, wherein each said side structure comprises a triangular perimeter member.

10. The massage chair of claim 1, wherein said cradle pivot means comprises a reversible linear actuating gear motor having an extension shaft telescopingly mounted within a shaft tube, said gear motor being pivotally mounted to said base frame and said extension shaft extending upwardly and being pivotally connected to said cradle;

wherein said gear motor operates in a first direction to extend said extension shaft out of said shaft tube and forwardly and thus pivoting said cradle backwardly on said base frame and wherein said gear motor operates in a second direction to retract said extension shaft into said shaft tube and rearwardly and thus pivoting said cradle forwardly on said base frame.

11. The massage chair of claim 10, additionally comprising a cradle stop element pin protruding inwardly from one of said side structures for stopping said cradle at a selected rearmost pivot position.

12. The massage chair of claim 1, wherein said vibration generation means comprises a plurality of oscillators.

13. The massage chair of claim 12, additionally comprising a control mechanism comprising a microprocessor mounted to said base frame, said microprocessor being electrically connected to each of said oscillators and to said cradle pivot means and controlling operation of said vibration generation means and controlling operation and direction of said cradle pivot means having programming with cradle positioning information including a certain cradle sitting position and at least one cradle reclined position and causing vibration generation means deactivation when said cradle is in any said at least one reclined position;

and a remote control box, and said remote control box is electrically connected to said microprocessor for chair operation by a seated person.

14. The massage chair of claim 13, wherein said control box comprises a control panel face including a plurality of control buttons which send signals to said microprocessor.
