Claim Text:
1. A locking device for a headrest, comprising: a headrest rod; a guide sleeve for the headrest rod; and a blocking element, wherein the blocking element is movable relative to the guide sleeve between a locking position, in which the blocking element is in engagement with a recess in the headrest rod, and an unlocking position, in which the blocking element is disengaged from recesses in the headrest rod, wherein the blocking element is pivotable in relation to the guide sleeve about an axis of rotation parallel to the headrest rod, wherein the blocking element is mounted in the guide sleeve in such a manner that, during a relative rotational movement between the guide sleeve and the headrest rod caused by an accident, the blocking element at least partially rotates together with the headrest rod about the axis of rotation, wherein the blocking element comprises a blocking bolt and an actuating element, wherein the actuating element comprises an outer segment and an inner segment, which are connected rigidly to each other, wherein the guide sleeve has two guide channels which extend parallel to the main direction of movement and in which free limbs of the outer segment are displaceably guided, wherein the free limbs have a curvature and/or rounded edges to enable the actuating element to rotate in relation to the guide sleeve about the axis of rotation parallel to the axial direction of the headrest rod.
