Abstract
The specification discloses a chair control in which a generally upright back support member is pivotally mounted to a support arm extending rearwardly from beneath a seat support member, there being a releasable securing means for securing or alowing adjustment of the angle of the back support member relative to the support arm. The releasable securing means passes through adjacent bottom walls in the back support member and the support arm. The support arm includes an integrally formed safety stop detent flange which prevents the back rest from falling all the way rearwardly in the event that the releasable securing means inadvertently disengages.
