ABSTRACT:
An angle-adjustable backrest device includes a backrest frame and an angle-adjusting device for connecting the backrest frame to a chair. The angle-adjusting device includes a mounting seat mounted on a leg frame and provided with positioning components, and a pivot seat mounted on a seat, connected to the backrest frame, and pivoted to the mounting seat. A locking unit includes a slide member mounted slidably on the backrest frame and having a positioning groove to engage the selected positioning component to thereby lock the backrest frame at a desired angle relative to the leg frame, a biasing member for biasing the slide member to an engaging position, and an actuator unit operable to drive movement of the slide member from the engaging position to a disengaging position.
