  • Patent number: 10654389
    Abstract: A headrest for a motor vehicle, including a base part for attachment to a backrest of a vehicle seat, a head part for contact with a head of a vehicle occupant, and an adjusting device between the base part and the head part for causing a substantially linear adjustment of the head part between a minimum and a maximum position. The adjusting device has an intermediate part and several pivot levers which pivot synchronously during adjustment and form a first articulated parallelogram between the head part and intermediate part and a second articulated parallelogram between the intermediate part and base part. The adjusting device includes a synchronizing lever for setting a relative orientation of the head part with respect to the base part during adjustment and wherein the headrest further has a latching device for fixing the headrest in a latching manner relative to the base part.
