A massage chair includes: a base unit; a rocker mechanism including an actuator that is coupled to the base unit, at least one output bar that is connected pivotally to the base unit, an input bar that is connected to and that is driven rotatably by the actuator, and a connecting bar that is connected pivotally to the input bar and the output bar; and a seat unit connected immovably to the output bar. The input bar, the output bar, the connecting bar, and the base unit cooperate to constitute a crank-rocker planar four-bar linkage. The actuator actuates rotation of the input bar, which in turn drives reciprocating swing motion of the output bar and the seat unit. |

1. A massage chair comprising:
a base unit; a rocker mechanism including
an actuator that is coupled to said base unit,at least one output bar that is connected pivotally to said base unit,an input bar that is connected to and that is driven rotatably by said actuator, anda connecting bar that has opposite ends connected pivotally and respectively to said input bar and said output bar, and that cooperates with said input bar, said output bar, and said base unit to constitute a crank-rocker planar four-bar linkage; and a seat unit connected immovably to said output bar; wherein said actuator actuates rotation of said input bar, which in turn drives reciprocating swing motion of said output bar and said seat unit. |
