Abstract

L’invention concerne un système (1) dans lequel au moins un premier manchon étant pourvu d’un tiroir (8) monté en coulissement radial et présentant une bordure de crantage (9) agencée pour pouvoir s’insérer dans un cran (5) quand ils sont en regard l’un de l’autre, la face inférieure (6) dudit cran étant pourvue d’une dent (11) saillant vers le haut, ladite bordure présente en regard de ladite dent une zone de rupture (12) de résistance à l’enfoncement agencée de sorte qu’un effort seuil appliqué à la première tige (3a) vers le haut entraîne une pénétration de ladite dent dans l’épaisseur de ladite zone, de manière à ancrer ledit tiroir sur ladite dent et à empêcher son retrait accidentel dudit cran en cas de choc violent de la tête du passager contre ledit appui-tête ayant pour effet de lui appliquer un effort vers le haut. Figure 2The invention relates to a system (1) in which at least a first sleeve is provided with a drawer (8) mounted in radial sliding and having a notch edge (9) arranged to be able to be inserted into a notch (5). when they are facing each other, the lower face (6) of said notch being provided with a tooth (11) projecting upwards, said edge presents facing said tooth a rupture zone (12) of resistance to depression arranged so that a threshold force applied to the first rod (3a) upwards causes said tooth to penetrate the thickness of said zone, so as to anchor said drawer on said tooth and to prevent its accidental removal of said notch in the event of a violent impact of the passenger's head against said headrest having the effect of applying an upward force to it. Figure 2
