Abstract
The specification discloses a chair control in which the tiltable member can be locked against movement with respect to the stationary member by means of a rigid locking plate pivotally mounted on the tilting member and rotatable by an actuator rod, having a bell crank type lever formed therein, into close proximity with the stationary member to thereby physically block relative movement between the tiltable and stationary members.
