  • the two axle profile stubs are designed in such a way that corresponding functional parts and functional sections, which are provided analogously to the armrest arrangement according to FIGS. 1 to 15, are mounted thereon and are movably mounted in a suitable manner.
  • the only difference is the arrangement of an actuating device, not shown, in order to achieve a synchronous unlocking or locking of the two radial carriers 8a.
  • this armrest arrangement when used as a center armrest in the area of a rear bench seat, a softer support for a spine of a vehicle occupant located on the rear bench seat is guaranteed than is the case with a continuous axle profile according to FIGS. 1 to 15.
  • a container holder cup holder
  • a container holder can be accommodated in a corresponding armrest body of the armrest arrangement, which cup holder forms an additional transverse connection between the two radial supports 8a and consequently improves transverse rigidity.

Abstract

Un agencement d'accoudoir, équipé d'une structure de support qui est fixée au véhicule à l'état monté et d'un corps d'accoudoir qui est monté, au moyen d'une structure porteuse, de manière à pouvoir pivoter par rapport à la structure de support entre une position de repos et une position de support, la structure de support présentant un profilé d'axe qui est fixé au véhicule à l'état monté et autour de l'axe longitudinal duquel la structure porteuse est montée de manière à pouvoir pivoter, est connu. Selon l'invention, au moins un élément de verrouillage est monté sur le profilé d'axe de manière à être guidé à force pour un mouvement longitudinal entre une position de libération et une position de verrouillage, dans laquelle l'élément de verrouillage bloque par complémentarité de forme la mobilité de pivotement de la structure porteuse, et un dispositif de commande mécanique est prévu qui coopère avec l'au moins un élément de verrouillage de telle sorte que l'élément de verrouillage puisse être transféré par le dispositif de commande de la position de libération vers la position de verrouillage en fonction d'un mouvement de pivotement de la structure porteuse. L'invention concerne également l'utilisation de cet agencement pour des voitures particulières.
