Abstract
A chair is disclosed having a mechanism with a spring unit that permits mutually synchronous deflection between a backrest and a seat over a range between a respective zero position of back and seat inclination and a respective maximum back or seat inclination. Stationary first and second axes of rotation extend through a base support of a carrier unit. A back carrier is articulated on the first axis of rotation, and a third axis of rotation extends through the back carrier. A front of a base plate lies movably on the base support and a rear of the base plate is articulated on the third axis of rotation. The base support has a U-shape with two arms thereof having portions extending upward to engage associated openings in the base plate. When the mechanism is deflected, a relative displacement between the arms and the openings occurs.
