Abstract

L’invention concerne un système d’appui-tête de siège de véhicule automobile, ledit système comprenant : une première tige (4) pourvue d’un cran d’anti-extraction (7) et d’une dent (14) saillant radialement de l’enveloppe générale de ladite première tige et présentant une face supérieure de butée, un premier manchon (9) pourvu d’un tiroir (11) monté en coulissement radial pour pouvoir s’insérer dans ledit cran et d’une gorge (16) s’étendant axialement de manière à recevoir ladite dent en coulissement, ledit premier manchon est pourvu d’au moins une face de butée réciproque (17) débouchant latéralement dans ladite gorge par rapport à sa direction d’extension, de manière à pouvoir recevoir ladite face de butée en cas de rotation axiale de ladite première tige pour l’ancrer sur ledit premier manchon en cas de choc de la tête d’un passager contre ledit appui-tête lui appliquant un effort vers le haut s’accompagnant de ladite rotation. Figure 4aThe invention relates to a motor vehicle seat headrest system, said system comprising: a first rod (4) provided with an anti-extraction notch (7) and a tooth (14) projecting radially of the general envelope of said first rod and having an upper abutment face, a first sleeve (9) provided with a drawer (11) mounted in radial sliding to be able to be inserted into said notch and with a groove (16 ) extending axially so as to receive said sliding tooth, said first sleeve is provided with at least one reciprocal abutment face (17) opening laterally into said groove with respect to its direction of extension, so as to be able to receive said abutment face in the event of axial rotation of said first rod to anchor it to said first sleeve in the event of an impact of the head of a passenger against said head restraint applying an upward force to it accompanied by said rotation .
