Head restraint for a motor vehicle seat

A head restraint for a motor vehicle seat, comprising:

• a headrest for resting on a head;
• at least one guide tube that can be latched to a backrest structure of the motor vehicle seat for movable guidance of the headrest in the direction of travel;
• an actuating rod mounted rotatably in the guide tube;
• an unlocking slide axially moveable in the guide tube between a rest position and an actuating position by rotation of the actuating rod in the guide tube, wherein, in the actuating position, the unlocking slide moves a latching element into an unlatched position, in which the latching element releases latching of the guide tube to the backrest structure, and, in the rest position, the latching element occupies a latched position, in which the latching element latches the guide tube to the backrest structure;
• and
• an actuating bar, guided in the headrest, for rotating the actuating rod, wherein the unlocking slide rests on the actuating rod via an oblique plane extending in a circumferential direction and facing in an axial direction, the unlocking slide being coupled to the guide tube to prevent relative rotation but allows relative axial movement by means of a stud guided in a groove.

• an unlocking slide axially moveable in the guide tube between a rest position and an actuating position by rotation of the actuating rod in the guide tube, the latching element having a latching spring that is elastic in a radial direction, and a spring arm coupled to the actuating rod wherein, in the actuating position, the unlocking slide moves a latching element into an unlatched position, in which the latching element releases latching of the guide tube to the backrest structure, and in which the unlocking slide presses the spring arm radially in and counter to a spring force of the latching element, and wherein in the rest position, the latching element occupies a latched position, in which the latching element latches the guide tube to the backrest structure;
• and
• an actuating bar, guided in the headrest, for rotating the actuating rod, wherein the unlocking slide has a contact surface that faces radially in and can be placed against the spring arm, the contact surface defining a funnel shape extending oblique to an axial direction.
