Abstract

The invention provides a chair frame and a massage chair. The chair frame comprises a base, a seat support, a shank support, a supporting arm and a driving device; the seat support is arranged on the upper portion of the base; the shank support is hinged to the seat support; furthermore, the front side of the shank support is used for supporting the legs of a user; the supporting arm is hinged to the seat support; one end of the supporting arm is a supporting end; the supporting end abuts against the portion, deviating from the hinge point, of the rear side of the shank support; the driving device is connected between the supporting arm and the seat support; and the driving device is configured to be capable of driving the supporting end to ascend or descend so as to drive the shank support to rotate relative to the seat support. On the basis that the functionality of the chair frame is guaranteed, when the shank support executes the leg retracting action, the shank support does not bear the pulling acting force of the supporting arm but moves through the gravity action borne by the shank support; the anti-pinch effect is good; and the safety is high.
