Abstract: The present invention discloses a dual motor lift chair for the elderly, which comprises a base, a seat lift, a back flexing mechanism and a leg flexing mechanism. The seat lift is arranged on the base, and the back flexing mechanism and the leg flexing mechanism are arranged on the seat lift. The present invention has a reasonable structure. When in the standing assistance configuration, the overall height of the lift chair increases, and the lift chair inclines forward at a certain angle, so that the center of gravity of the elderly rises and moves forward. Hence, an effective result of standing assistance is achieved, and the experience effect of the standing assistance is ensured. Furthermore, by setting the leg flexing mechanism and the back flexing mechanism, the flex of the body may be adjusted, and hence the comfortability of the chair is improved.

Abstract: An electric sofa stent comprising two coupled assemblies, a drive link and a motor drive. When the motor drive is driving the drive link into rotation, the headrest is driven to rotate via the coupled assemblies. Each of the coupled assemblies comprises of a first connector, a second connector, a third connector, a first fixture and a headrest connector. One end of the first connector is fixedly connected to the drive link, and the other end is pivot connected to one end of the second connector. The other end of the second connector is pivot connected to one end of the third connector. The other end of the third connector is pivot connected to the first fixture, which is fixed on the side frame. The upper end of the headrest connector is fixedly connected to the headrest, and the lower end is pivot connected to the third connector.
