Abstract
A chair control mechanism for positioning between the seat and seat support of a chair. The chair control mechanism includes a base section for mounting to a seat support such as an adjustable height cylinder, and a seat mounting section pivotably interconnected with the base section. A seat is mounted to the seat mounting section, and is pivotable about a seat pivot axis. An adjustable position back mounting arrangement is pivotably interconnected with the seat mounting section, and the chair back is engageable with the back mounting section. A variable stop arrangement is interposed between the base section and the seat mounting section, for varying the range of pivoting movement of the seat relative to the seat support. The back can be selectively locked in one of a number of predetermined positions relative to the seat by operation of a variable position back locking arrangement.
