ABSTRACT:
The seat plate of a chair control is pivotably mounted to the main frame so as to be tiltable forwardly and rearwardly. An arm extending from the seat plate has a slot which receives a pin of the main frame to limit forward and rearward tilting of the seat plate. The back bracket is configured such that either the forward or the rearward tilting of the seat plate is further limited by abutment with the back bracket, dependent upon the reclining position of the back bracket. However, the seat plate has a range of tilting motion irrespective of the tilt of the back bracket for the chair control.
