Abstract

Pour obtenir dans cette chaise la courbure élastique qui doit être nécessairement prévue dans la région du milieu de la hauteur du dossier, et présente une allure conforme à la configuration naturelle de la colonne vertébrale, le dossier qui dans son segment situé au-dessus de cette ligne de flexion, est raccordé à la cuvette d'assise par une liaison relativement rigide, se prolonge vers le haut par une zone à flexibilité croissante. Afin que, lorsque la chaise est chargée, on puisse obtenir dans l'appui d'épaules qui fait suite à l'extrémité supérieure du dossier une configuration voulue, analogue à la courbure de la colonne vertébrale, on interpose dans l'organe de liaison entre l'extrémité supérieure du dossier et l'appui d'épaules un élément élastique à dureté progressivement croissante
