The invention relates to a headrest for a vehicle seat. The headrest has at least one first sub-piece which faces the head of a seat occupant, and the headrest has a second sub-piece, at least one energy storage device with a trigger actuator being arranged between the first sub-piece and the second sub-piece. The first sub-piece can be moved relative to the second sub-piece out of a use position into a safety position along a movement direction towards the head of the seat occupant as a result of an accident under the effect of a discharge of the energy storage device, which is actuated by means of the trigger actuator. The headrest is configured such that the volume of an expansion area is increased while the first sub-piece is moved relative to the second sub-piece as a result of an accident and by means of the effect of the discharge of the energy storage device, said headrest having a sealing means between the first sub-piece and the second sub-piece in order to delimit the expansion area. |
