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.
Claims13
A headrest for a vehicle seat, comprising:
- at least one first section that is configured to be oriented towards a head of a seat occupant;
- a second section;
- a third section, wherein the second section is arranged substantially between the first section and the third section, wherein the first section is configured to be displaced in a direction of displacement, due to an effect of a relative displacement of the second section from a working position into a safety position in an event of an accident and into a comfort position, the direction of displacement being in a direction of the head of the seat occupant;
- and
- a blocking device configured to block or minimize displacement of the first section counter to the direction of displacement,
- wherein the blocking device is asymmetrical in relation to a central plane of the headrest extending substantially in a vertical manner and a parallel manner in relation to the direction of displacement in a built-in position of the headrest, and
- wherein the blocking device is configured to be actuated by an actuation element which is able to be arranged symmetrically in relation to the central plane.
