Abstract

A head rest for a vehicle seat has at least one first section of the head rest that is oriented towards the head of the seat occupant, a second section, a third section, and a blocking device in which the second section is arranged essentially between the first and third sections. The first section can be displaced, due to the relative displacement of the second section, from a working position into a safety position and a comfort position. The blocking device blocks or minimizes the displacement of the first section of the head rest. The blocking device is asymmetrical in relation to a central plane of the head rest and can be actuated by an actuation element that is arranged symmetrically in relation to the central plane.
