Abstract
An adjustment mechanism for a chair includes a housing and an adjustment element that is movable relative to the housing into a selectable one of at least two adjustment positions. Preferably, when assembled to a chair, the housing, possibly along with other elements of the chair, such as the armrest, completely encloses interlocking adjustment surfaces of the adjustment mechanism with the exception of a guide slot of the housing through which movement of the adjustment element is permitted between the at least two adjustment positions. The guide slot has a maximum width dimension sufficiently small to inhibit or prevent foreign objects from coming into contact with the interlocking adjustment surfaces of the adjustment mechanism.
