Mechanical seating device with an automatically adjusted headrest

A seating device comprising a seat (4), a reclining back frame (3), a head frame (1) and a base (5), the back frame (3) being pivotally attached relative to the base (5) in a first pivot point (E), and the head frame (1) is hinged to an upper end of the back frame in a third pivot point (A), wherein the back frame (3) is adjustable between an upright position with the head frame (1) in an upright position, a reclined position with the head frame (1) in an upright position, and a further reclined sleeping position, wherein the seating device further includes;

• a motion control lever (7) pivotally attached to the base (5) in a fourth pivot point (D);
• a motion resisting element resisting motion between head frame (1) and the back frame (3);
• a pulling element (2) extending from a fifth pivot point (F) on the motion control lever (7) to a sixth pivot point (B) on the head frame;
• an engagement element (12), mechanically connected to the reclining back frame (3);
• an impact face (13) mechanically connected to the pivoted motion control lever (7);
• and
• wherein the impact face (13) and the motion control lever (7) are adapted to be out of mechanical contact when the back frame (3) is in the upright position with the head frame (1) in an upright position and is adapted to be in mechanical contact when back frame (3) is moved between a reclined position with the head frame (1) in an upright position and a further reclined sleeping position, whereby the head frame (1) is pushed back to a further reclined sleeping position.
