Abstract
A remotely controlled powered chair may include a support frame, a seat pivotally mounted on the support frame, an rotary actuator mounted between the support frame and the seat to drive the seat to move relative to the support frame, a backrest pivotally mounted on the seat, and a linear actuator mounted between the seat and the backrest to drive the backrest to move relative to the seat. Thus, the rotary actuator may be controlled by an electrically control device to drive the seat to pivot relative to the support frame reciprocally in a pendulum manner so that the seat is pivoted relative to the support frame automatically. In addition, the linear actuator may be controlled by the electrically control device to adjust the inclined angle of the backrest so as to provide a comfortable sensation to the user. A remotely controlled powered chair may include a base assembly. A chair frame is supported on the base assembly. An actuator mechanism may communicate with the base assembly and the chair frame, and is operable to actuate the chair frame between first and second positions.
