Abstract

L'invention concerne un dispositif d'ajustement servant à l'ajustement électrique d'une position d'appuie-tête. L'invention vise à améliorer ledit dispositif d'ajustement de manière à ce que l'ensemble du dispositif d'ajustement puisse être disposé à l'intérieur de l'appuie-tête. L'invention propose à cet effet que le dispositif d'ajustement comporte au moins une broche réalisée sous la forme d'une broche filetée et au moins un moteur électrique, et que le moteur électrique soit disposé de manière mobile par rapport à la broche de telle manière qu'un déplacement en rotation du rotor du moteur électrique entraîne un déplacement par translation du moteur électrique le long de la broche, ou que la broche soit disposée de manière mobile par rapport au moteur électrique de telle manière qu'un déplacement en rotation d'un rotor du moteur électrique entraîne un déplacement par translation de la broche. Le dispositif d'ajustement comporte une transmission. La transmission est en liaison fonctionnelle mécanique avec la broche afin de transformer un déplacement en rotation du rotor en le déplacement par translation du moteur électrique le long de la broche ou en un déplacement par translation de la broche.
