Abstract
A locking mechanism (11) suitable for use with office type chairs comprising an operating lever (13) movable between a locking position in which locking takes place and an unlocking position in which unlocking takes place, a spring, which biases the lever (13) into the locking position and a catch (23, 27, 29), which holds the lever (13) in the unlocking position upon movement of the lever (13) into the unlocking position. The catch (23, 27, 29) is disengaged when the lever (13) moves past the unlocking position. Upon disengagement of the catch, the lever (13) returns to the locking position under the action of the spring.
