Abstract
Abstract A single control for an adjustable chair for aircraft, or the like. Different embodiments of the chair are capable of different combinations of fore-and-aft linear movement, lateral linear movement, selective directional linear movement, swiveling movement, tilting movement, and the like. The chair includes different locking means for locking it against the different movements, respectively. A single, manually operable control means mechanically connected to the different locking means used in a particular embodiment unlocks all of them so that the chair can be maneuvered into any desired position by the body of a person seated therein. Upon releasing the single control means, all of the locking means automatically relock.
