Abstract

L'invention concerne un élément d'appuie-tête (1), comprenant une zone d'appui centrale et deux zones d'appui latérales, - les zones d'appui latérales pouvant pivoter par rapport à la zone d'appui centrale autour d'un axe de pivotement latéral s'étendant au moins sensiblement parallèlement à une surface d'appui de la zone d'appui centrale, de telle sorte que respectivement un angle des surfaces d'appui des zones d'appui latérales par rapport à la surface d'appui de la zone d'appui centrale peut être réglé de façon variable et - la zone d'appui centrale et les zones d'appui latérales peuvent pivoter conjointement autour d'un axe de pivotement transversal s'étendant au moins sensiblement perpendiculairement aux axes de pivotement latéraux, de telle sorte qu'un réglage des zones d'appui dans la direction longitudinale du véhicule est possible. L'invention concerne en outre un appuie-tête, comprenant un élément d'appuie-tête (1) de ce type.
