Abstract
The invention relates to a multi-link lift chair frame for a lift chair, which has a reasonable structural and multifunctional design, is highly reliable, and is capable of implementing a lying position, a relaxing position and a sitting position of a lift chair seat. The multi-link lift chair frame includes a deployment mechanism, a footrest mechanism, a backrest mechanism, a mounting and locating mechanism, a support mechanism, and a limit mechanism. Through adjusting the footrest mechanism, the backrest mechanism, the mounting and locating mechanism, and the support mechanism in the lift chair, the lift chair is adjusted among three positions: the lying position, the relaxing position and the sitting position, implementing multiple functions on one lift chair. More demanding requirements on a lift chair are met, and costumers can purchase less lift chairs or chairs of different positions, thereby reducing the cost.
