Chairs of the recliner type are chairs with adjustable parts, especially with a backrest which is moved both from a rest position to a normal sitting position. Such chairs may also have other adjustable parts, for example a footrest that can swing up and down as required.

Some such recliner chairs are also equipped with a special neck articulation.

It has, however, been a disadvantage that the neck articulation's angle with respect to the backrest does not change in accordance with the position of the backrest, that is, the angle between the neck articulation and the backrest is the same, regardless of the angle of the backrest with respect to the base.

The neck articulation according to the present invention provides a possibil- ity to adjust the motion of the neck articulation with respect to the backrest when the backrest moves. This is achieved with a neck articulation according to the invention as it is defined with the features set forth in the claims.

On the drawing, figure 1 shows a chair frame without cover or foam, seen from the side and in a standing position, figure 2 shows the chair in figure 1 in re- clining position, and figure 3 shows schematically the mechanism that allows ad- justing of the neck articulation angle with respect to the backrest.

As disclosed in figures 1 and 2, a neck articulation 9 is pivotally fastened to a chair's backrest 5. The backrest 5 is in turn fastened to a backrest mounting 4 which is PivotTable with respect to the seat 8.

The steel frame shown on figures 1 and 2 is imbedded in cold foam in such a way that the neck articulation 9 will be pressed back by the cold foam to the molded position when it is released from another position. For this reason, there is no need to equip the neck articulation with a spring to bring the neck articulation back to the start position after a change.

A stay 1 is with one end fastened to one end of an arm, whose other end is fastened to the neck articulation 9 in such a way that turning of the arm also will turn the neck articulation with respect to the chair backrest 5. The other end of the stay 1 is in the pivot point 2 fastened to an arm 3 which is pivotally joined to the back rest mounting 4. Screw 6 forms a support for the arm 3, in that screw 6, by screwing in or out adjust this stopping point for the arm 3. The screw 6 is mounted in a bracket 7 fastened to the chairs sit frame 8.

When the backrest 5 tips back, the arm 7 will press against the screw 6, and thereby maintain the stay's 1 turning point 2. Thereby the stay 1 through the arm will tip the neck articulation 9 forward, against the spring action from foam which encap- sulates both the backrest 5 and the neck articulation 9. In that way the neck articula- tion 9 will not follow the motion of the backrest 5 in the same angle position, but rather the neck articulation 9 will move with respect to the backrest 5 when the back- rest 5 tips forward or backward. In what degree the motion of the articulation 9 shall vary from the motion of the backrest 5, is determined by the position of the screw 6, and the position of the arm 3 during the motion. Determining for this motion is also the distance between the pivot point 2 and the mounting of the arms 3 on the backrest 5.

Such a relative motion is desired by the user to be able to adapt as comfort- able a position as possible in all positions of the chair, that is the position of the back- rest.

With the neck articulation 9 according to the present invention, the backrest may be mounted and dismounted as a separate unit without additional connections.

This is achieved because both the backrests 5, the arm 3 and the stay 1 comprise one assembly together with the back rest mounting 4.
