Abstract

L'invention concerne un appuie-tête de siège de véhicule, notamment de voiture, qui peut être déplacé manuellement ou au moyen d'une télécommande d'une position passive à une position active et inversement. Conformément à l'invention, l'appuie-tête est constitué d'un support arrière mobile (2) relié de manière rotative à l'arrière du siège, le plan de rotation du support arrière (2) correspondant approximativement au plan de l'arrière du siège. Une cheville (3) est reliée de façon permanente au support arrière (2) et s'introduit par rotation dans une gaine (4) reliée à l'arrière du siège. La cheville (3) est reliée à la plaquette de blocage (5) associée à un siège de blocage (6) auquel est couplée une goupille d'arrêt (7) supportée élastiquement (7). De la position de verrouillage, la goupille d'arrêt (7) est déplacée soit au moyen d'un levier (9) soit d'un électroaimant (11). Dans un autre mode de réalisation, le support arrière (2) peut être déplacé au moyen d'une vis sans fin.
