A head rest for a vehicle seat includes: at least one first section that is oriented towards the head of the seat occupant, a second section, and a third section, wherein the second section is arranged essentially between the first and third sections. In the event of an accident, the first section can be displaced in the direction of displacement, due to the effect of a relative displacement of the second section from a working position into a safety position in the direction of the head of the seat occupant. The relative movement of the sections is a rotation about an essentially parallel rotational axis in the direction of displacement. A mounting of the first section in relation to the second section is provided during the relative displacement about the rotational axis. The first section comprises a first bearing surface and the second section comprises a second bearing surface. |

1. A headrest for a vehicle seat, comprising:
at least one first section that is oriented towards a head of a seat occupant; a second section; and a third section, wherein the second section is arranged substantially between the first section and the third section, wherein, in an event of an accident, the at least one first section is configured to be displaceable in a direction of displacement, due to an effect of a relative movement of the second section from a working position into one of a safety position, a comfort position, and a combination thereof in a direction of the head of the seat occupant, wherein the relative movement of the second section is a rotation about a rotational axis substantially parallel to the direction of displacement, wherein a mounting of the first section relative to the second section is provided during the relative movement about the rotational axis, wherein the first section comprises a first bearing surface and the second section comprises a second bearing surface, wherein a rolling bearing is provided in a region of the first and second bearing surfaces, and wherein the rolling bearing comprises a bearing cage comprising a rolling element. |
