Abstract
The invention relates to a headrest system comprising:
- a headrest device (1);
- a plurality of sensors (2, 3); and
- an electromechanical headrest device positioning system, associated to said sensors (2, 3). Data are recorded during an upward movement of the headrest device (1), relating to the distance between the headrest device (1) and the head in a plurality of positions of the headrest device (1) throughout said upward movement. The upward movement ends when, through the sensors, the system detects that the headrest is at a certain height. Based on this data recorded during the upward movement, the headrest device (1) is moved substantially horizontally until it is located at a certain distance from the head.
