ABSTRACT:
A chair includes an upper frame disposed above and pivoted to a lower frame. A stopping device includes a slide mounted slidably on the upper frame, and a stopping member. The slide is slidable between a first position, where the stopping member is offset from a rear plate of the lower frame in a longitudinal direction, and a second position, where the stopping member is aligned with the rear plate in a vertical direction. A cam mechanism includes a cam connected movably to side plates of the lower frame and a cam follower formed on the slide and engaging the cam in such a manner that movement of the cam from a releasing position to a restricting position results in movement of the slide from the first position to the second position.
