An adjuster device for height adjustment of a headrest (1, 2) on a seat (3) is disclosed, comprising a head support, provided with adjuster means (4) which may move in an adjustment direction (A), embodied such as to be able to engage with a headrest (1, 2) which may be inserted in the headrest housing, whereby drive means for generating an adjustment movement for the adjuster means (4) are further provided. The drive means (4) thus form a physically-separate unit from the headrest housing. The transmission of the adjustment movement of the drive means (8) to the adjuster means (4) is carried out by means of a flexible transmission means (16), such as, for example, a flexible shaft or a bowden cable. The drive unit (8) can thus be positioned independently of the headrest housing.

L'invention concerne un dispositif de réglage servant à régler en hauteur l'appuie-tête (1, 2) d'un siège (3) et comprenant des moyens de réglage (4) déplaçables dans un sens de réglage (A), réalisés de sorte qu'ils peuvent entrer en prise avec un appuie-tête (1, 2) insérable dans le logement d'appuie-tête. Le dispositif selon l'invention comprend également des moyens d'entraînement (8) servant à générer un mouvement de réglage pour les moyens de réglage (4) et formant une unité séparée spatialement du logement d'appuie-tête. Le mouvement de réglage des moyens d'entraînement (8) est ce faisant transmis aux moyens de réglage (4) par des moyens de transmission flexibles (16), un arbre flexible ou un câble Bowden par exemple. Il est ainsi possible de placer l'unité d'entraînement (8) indépendamment du logement d'appuie-tête.
