Abstract

In a neck support for a chair, a head cushion is articulated, via an articulation bearing, on a guide sleeve displaced on a retaining bar, articulated on the top edge of a backrest via a further articulation bearing, the retaining bar and the guide sleeve being of rectilinear design, this resulting in linear height adjustability of the neck support. The bottom articulation bearing and preferably also the top articulation bearing each comprise a cylinder on the retaining bar and two cylinders on a bearing foot or on a link plate, it being possible for the first cylinder to rotate in a controlled manner between the two second cylinders via blocks.
