  • Locking device for a headrest
    Patent number: 9346383
    Abstract: A locking device for a headrest has a headrest rod, a guide sleeve for the headrest rod and a blocking element. The blocking element is displaceable 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 a unlocking position, in which the blocking element is not in engagement with recesses in the headrest rod. The blocking element is pivotable in relation to the guide sleeve about an axis of rotation parallel to the headrest rod. The blocking element is mounted in the guide sleeve such that, when there is a relative rotational movement between the guide sleeve and the headrest rod, the blocking element rotates at least partially jointly in conjunction with the headrest rod about the axis of rotation.
