Description

technical field [0001] The invention belongs to the field of furniture, and relates to a seat such as a lounge chair, a sofa, etc., and in particular to an electromechanical stretching device used therein. Background technique [0002] At present, many furniture such as lounge chairs and sofas are equipped with electromechanical extension devices, on which backrests, seat cushions and leg rests are installed, and electromechanical extension devices are usually a combination of various mechanical connectors. The components are operable to provide various comfort features, such as independent reclining movement of the seat assembly, and actuation of the extendable leg rest assembly and associated tilting of the chair frame. While many conventional recliners operate satisfactorily, furniture manufacturers are continually pursuing improved chair frames and functional frames that reduce system complexity, improve smooth operation, and occupant comfort. [0003] At present, the e...
