An automobile seat possesses a seat back that includes a seat back frame to which an restraining device for a headrest is mounted. The headrest may be displaced from an initial position into an extended position against the head of the seat occupant. A locking process is provided by means of which the restraining device may be maintained in its extended position with respect to the seat back frame. The locking process device includes an engaging element pre-tensioned by a spring that may engage with the engagement recess formed on the restraining device. The locking process device includes a disengaging element to be operated by the seat occupant or other person that brings the engaging element out of engagement with the engaging recess in the maintained condition of the restraining device against the force of the spring.
