A shape-adjusting mechanism for a backrest has a lumbar basket which includes a pair of supports spaced apart along a predetermined axis. Resilient axial ribs are fastened between the brackets, and resilient transverseribs are fastened to the axial ribs. The axial ribs are structured to flex as the supports are drawn together, to achieve a profile that better conforms to the shape of a user's spine. To that end, each axial rib is stamped with reinforcingflanges that extend partially along its length and produce lengthwise rib sections of different bending resistance that determine the profile of the lumbar basket in its flexed state. No separate stiffening component or additional stamping operation is required
Mécanisme de réglage de la forme d'un dossier. Ce mécanisme comprend une coquille lombaire ayant deux supports espacés le long d'un axe prédéterminé. Des nervures axiales élastiques sont attachées entre les pattes de fixation, et des nervures transversales élastiques sont fixées aux nervures axiales. La structure des nervures axiales leur permet de fléchir lorsque les supports se rapprochent, afin d'obtenir une courbe s'adaptant mieux au dos de l'utilisateur. € cette fin, chaque nervure axiale est poinçonnée à l'aide de brides de renfort se prolongeant partiellement sur sa longueur, afin de fournir des sections de nervures longitudinales de différents niveaux de résistance à la flexion qui définissent la courbe de la coquille lombaire en position fléchie. Aucun composant de raidissage ni aucune opération de poinçonnage supplémentaire ne sont requis.
