L'invention concerne également un véhicule automobile équipé d'au moins une telle armature,  The invention also relates to a motor vehicle equipped with at least one such frame,
Les armatures de dossiers des sièges des rangs arrière trois places de véhicule automobile sont généralement constituées d'une première armature correspondant à un dossier de siège latéral, et d'une seconde armature de plus grande largeur correspondant au dossier de siège latéral opposé et au dossier de siège central.  Backrest seats of the three-seater rear row seats of a motor vehicle generally consist of a first frame corresponding to a lateral seat back, and a second frame of greater width corresponding to the opposite side seat back and backrest central seat.
Les première et seconde armatures peuvent être indépendamment rabattues pour conférer au rang de siège arrière l'appellation de banquette 2/3 - 1/3 illustrant la capacité à rabattre 1 /3 ou 2/3 du rang de sièges arrière pour augmenter le volume de chargement du véhicule.  The first and second frames can be independently folded to give the rear seat row the name of seat 2/3 - 1/3 illustrating the ability to fold 1/3 or 2/3 of the row of rear seats to increase the volume of loading the vehicle.
Ces armatures sont spécifiquement dimensionnées selon le véhicule dans lequel elles sont montées. Par conséquent, il n'est pas possible d'utiliser ces armatures, et en particulier la deuxième armature couvrant le dossier de siège latéral et le dossier de siège central, pour des véhicules présentant des largeurs différentes de rang de sièges arrière.  These frames are specifically sized according to the vehicle in which they are mounted. Therefore, it is not possible to use these frames, and in particular the second frame covering the lateral seat back and the central seat back, for vehicles with different widths of rear seat rank.
Par ailleurs, ces armatures présentent un poids important. Or, la réduction des émissions de dioxyde de carbone passe notamment par la réduction du poids des véhicules.  Moreover, these frames have a significant weight. However, the reduction of carbon dioxide emissions includes reducing the weight of vehicles.
En référence à la figure 1 , la publication WO2013001 19 décrit une armature de dossier de siège 1 comportant un premier élément de support 2 formant le fond du dossier d'un siège latéral et principalement constitué d'un cadre rigide tubulaire 3 sur lequel un élément de support d'extension 4 réalisé en un pliage de fil d'acier 5 formant le fond du dossier de siège central est solidarisé.  With reference to FIG. 1, the publication WO2013001 19 describes a seat back frame 1 comprising a first support element 2 forming the bottom of the back of a side seat and consisting mainly of a rigid tubular frame 3 on which an element extension support 4 made of a folding steel wire 5 forming the bottom of the central seat back is secured.
L'armature comporte également un second élément de support 6 identique ou symétrique au premier élément de support 2 et formant le fond du dossier du siège latéral opposé. Comme visible sur cette figure, l'élément de support d'extension 4 peut prévoir une armature d'appui tête 7 soudée sur sa partie supérieure et destinée à recevoir le garnissage de l'appui tête. The armature also comprises a second support element 6 identical or symmetrical to the first support element 2 and forming the bottom of the back of the opposite side seat. As visible in this figure, the extension support member 4 may provide a head support frame 7 welded on its upper part and intended to receive the lining of the head support.
Selon cette configuration, il n'est pas possible de prévoir la présence d'un guide d'appui tête assurant le réglage en hauteur de l'appui tête.  According to this configuration, it is not possible to provide the presence of a head support guide ensuring the height adjustment of the headrest.
