Abstract

A dental patient chair has an adjustable headrest on a headrest carrier. The headrest is pivotably hinged around a transverse first axis on a bracing member which, in turn, is adjustable in the longitudinal direction in the backrest. In addition, the headrest is connected by a linkage which is pivotably connected on a second axis offset from the first axis so that movement of the linkage causes tilting of the headrest. The linkage is shifted as the headrest carrier is extended and contracted.
