A headrest for a vehicle seat, in particular a motor vehicle seat, has a carrier, an impact element that can be extended relative to the carrier in the event of a crash, a drive means for extending the impact element, and components for holding and releasing the drive means. The components comprise an electromagnet ( 17 ) that is controlled and energized by a control unit, and an actuator box ( 41 ). The actuator box ( 41 ) is arranged inside the headrest as an internal control unit containing the components needed for energizing the electromagnet ( 17 ), and for control purposes it is connected to a control unit (C) arranged outside the headrest.
