Multifunctional leisure chair frame structure and sitting supporting method thereof

Abstract

The invention discloses a multifunctional leisure chair frame structure and a sitting supporting method. The multifunctional leisure chair frame structure comprises a back supporting piece, a seat supporting piece, a foot rest and a supporting seat, a first connecting rod mechanism and a tilting rod are arranged among the rear end of the seat supporting piece, the back supporting piece and the supporting seat; a second connecting rod mechanism is arranged between the seat supporting piece and the supporting seat; a third connecting rod mechanism is also arranged among the seat supporting piece, the foot rest and the supporting seat; when the back supporting piece leans backwards under thrust, the seat supporting piece is lifted up around the supporting seat under the supporting action of the tilting rod and the linkage action of the first connecting rod mechanism, and the foot rest is turned over forwards under the linkage action of the third connecting rod mechanism; when the back supporting piece stops moving, the back supporting piece, the seat supporting piece and the foot rest are kept relatively fixed in a force balance state; when the foot rest bears downward pressing thrust, the foot rest reversely conducts folding movement, the seat supporting piece descends and drives the back supporting piece to incline forwards, and when the foot rest stops moving, the back supporting piece, the seat supporting piece and the foot rest are kept relatively fixed as well.

Description

technical field [0001] The invention relates to the field of seats, in particular to a frame structure of a multifunctional leisure chair and a method for supporting and sitting the same. Background technique [0002] Nowadays, as consumers have higher and higher functional requirements for seats, the market for multifunctional leisure chairs has developed rapidly in recent years. From the earliest multi-functional leisure chair with the most single technology, to the new multi-functional leisure chair that pays attention to ergonomics; from the beginning, the multi-functional leisure chair will lose the support for the user's waist when the user is in the tilted state, that is, our Commonly known as "running the waist", it has been developed to the current "seat-back linkage technology", which can make the user's buttocks and seat surface relatively fixed during the leaning process, eliminating the feeling of rubbing the back; there is also a multi-functional leisure chair ...

AI Technical Summary

Problems solved by technology

In the stowed position, the seat is basically in a horizontal position, and the backrest is set to be basically upright for normal sitting posture; in the unfolded position, the backrest leans back, and the backrest and seat form an obtuse angle for rest or sleep; leisure chair use It can only switch between these two positions, which makes the lounge chair cramped and cannot stay at any position between the folded position or the unfolded position; for this reason, the usual practice is to place a drive motor inside the lounge chair , the driving force is provided by the driving motor so that the leisure chair can be locked and stopped at any position; although the electric drive device has the advantages of convenient operation and quick adjustment, but because the motor is installed in the multi-functional leisure chair, it is expensive and difficult to maintain. It cannot be widely promoted and applied; therefore, how to realize the leisure chair can adjust the user's gravity and stay between the folded position and the unfolded position when the user uses it through the frame structure of the leisure chair itself has become a constant pursuit of many furniture manufacturers to develop and improve. direction
