摘要

Seat comprises a back (4) with a headrest (5) on top, which has an internal structure pivoting on the axis (9) formed by the top end of the rigid rod (11) from the back seat. A resisting element (11,20) is placed on the lower end of the headrest and exerts a higher resisting torque when the headrest is forced backwards than when it is forced forwards.
