An adjustment mechanism for a headrest for a seat, comprising:
- a scissor lever,
- at least one first lever arm and at least one second lever arm which can be
- pivoted relative to one another about a common main pivot axis (S) at a common intersection point (P),
- a compensating lever arm is arranged at at least one lever arm end of each lever arm so as to be pivotable about a compensating pivot axis (AS1, AS2) running parallel to the main pivot axis (S), wherein
- a free end of each compensating lever arm comprises an attachment structure for attaching the compensating lever arm to a body and
- a lever arm end opposite the compensating lever arm of each lever arm comprises an attachment structure for attaching the lever arm to a body.
A headrest for a vehicle seat, which has a headrest body, said headrest comprising:
- a base element designed for attachment to a seat,
- a head rest element with a head rest surface and
- an adjustment mechanism which is mechanically coupled to the base element and to the head rest element and is arranged between the base element and the head rest element for longitudinally displacing the head rest element in a first seat direction (X) and in the direction opposite to said first seat direction.
