Abstract

A chair, in particular an office chair, comprises a pedestal; a seat support propped thereon; a seat supporting itself on the seat support; a backrest support mounted on the seat support; a headrest support mounted on the backrest support; and a headrest mounted on the headrest support and having a height setting mechanism for height adjustment of the headrest and an inclination setting mechanism for adjustment of an angle of inclination a of the headrest.

Claims

1. A chair, in particular an office chair, comprising

a pedestal (2);

a seat support (5) propped thereon;

a seat (6) supporting itself on the seat support (5);

a backrest support (7) for a backrest (8), the backrest support (7) being mounted on the seat support (5);

a headrest support (9) mounted on the backrest support (7); and

a headrest (10) mounted on the headrest support (9), the headrest (10) having

a height setting mechanism for height adjustment of the headrest (10), wherein the height setting mechanism comprises at least one rail (16) fixedly connected with the headrest (10), wherein at least one friction guide shoe (22) is frictionally displaceably guided on the at least one rail (16) for changing the height of the headrest (10) and

an inclination setting mechanism for adjustment of an angle of inclination a of the headrest (10), wherein the inclination setting mechanism comprises a shaft (19) that is supported in relation to the headrest support (9), wherein the at least one friction guide shoe (22) is lodged frictionally rotatably in relation to the shaft (19) for pivoting the headrest (10).

2. A chair according to claim 1, wherein the at least one rail (16) is curved relative to a vertical plane.

3. A chair according to claim 1, wherein two pairs of rails (16) are provided.

4. A chair according to claim 3, wherein the two pairs of rails (16) are united to form a frame by two cross bars (17).

5. A chair according to claim 4, wherein the frame (15) comprises a facing for definition of the outer contour of the headrest (10).

6. A chair according to claim 5, wherein the facing has a cover.

7. A chair according to claim 5, wherein the facing comprises two cover plates (31) which are fixed to the front and the rear of the frame (15).

8. A chair according to claim 7, wherein the cover plates (31) have recesses (32) along the range a friction guide shoe (22) travels through upon height adjustment.

9. A chair according to claim 5, wherein the facing comprises two frontal plates (33) which are mounted on the fronts of the frame (15).

10. A chair according to claim 9, wherein the two frontal plates (33) have two oblong holes (34) for displacing the shaft (19).

11. A chair according to claim 4, wherein the frame (15) is joined to the shaft (19) by way of two pairs of friction guide shoes (22).

12. A chair according to claim 11, wherein two friction guide shoes (22) are united to form a pair (26) by screws (25), the pair (26) enclosing a pair of rails (16).

13. A chair according to claim 12, wherein friction between the friction guide shoes (22) and rails (16) is adjustable by the screws (25).

14. A chair according to claim 12, wherein each friction guide shoe (22) has a hole (23) that the shaft (19) passes through.

15. A chair according to claim 14, wherein inner fronts (27) of the friction guide shoes (22) have a widening (28) of the hole (23), whereby a chamber between the shaft (19) and the two friction guide shoes (22) of a pair (26) is originated to place a rubber ring (29) therein.

16. A chair according to claim 15, wherein the rubber ring (29) is pressed against the shaft (19) when two friction guide shoes (22) are screwed together by the screws (25).

17. A chair according to claim 16, wherein friction is adjustable between the shaft (19) and the frame (15) by the screws (25).

18. A chair according to claim 1, wherein the shaft (19) is non-rotatably fixed relative to the headrest support (9).
