Abstract
An ergonomic chair includes a back component and a seat component. The back component includes an upper back support, a lower back support, a seat back frame that is elastically deformed under traction or squeezing, and a locking mechanism for maintaining positions of the above three components to be relatively fixed. The lower back support is connected to the seat component through a connecting rod. A lower end of the upper back support is rotatably connected to an upper end of the lower back support. Upper and lower ends of the seat back frame are respectively hinged on an upper portion of the back support and the lower portion of the lower back support.

An ergonomic chair, comprising a back component and a seat component, wherein the back component comprises an upper back support, a lower back support, a seat back frame elastically deformed under traction or squeezing, and a locking mechanism for maintaining the upper back support, the lower back support, and the seat back frame at relatively fixed positions;
- the lower back support is connected to the seat component through a connecting rod, a lower end of the upper back support is rotatably connected to an upper end of the lower back support, and upper and lower ends of the seat back frame are respectively hinged to an upper portion of the upper back support and a lower portion of the lower back support;
- when the locking mechanism is unlocked, the upper back support is rotated, and a straight-line distance between upper and lower hinge points of the seat back frame changes, so that shape and angle of the seat back frame change;
- when the locking mechanism is locked, the upper back support, the lower back support, and the seat back frame maintain a relatively fixed posture.
