Abstract

Un soutien lombaire à courbature progressive situé dans le dossier dun fauteuil de bureau ou de maison permet à un utilisateur de sasseoir près dune surface de travail (p. ex. un bureau ou une table). Le dossier du fauteuil sincline vers larrière et vers lavant lorsque lutilisateur transfère son poids vers lavant et vers larrière. Le soutien lombaire dynamique comprend un support dorsal coussiné fabriqué dun matériau résilient qui répond à une force de compression appliquée sur le matériau lorsque lutilisateur se couche contre la chaise. Plus particulièrement, une tige dinclinaison sensible à la pression coulisse de haut en bas sur une paire de blocs de guidage inclinés pour apporter le support dorsal coussiné à passer dune configuration convexe, dans laquelle il soutient le bas du dos de lutilisateur et fournit un soutien à la bonne posture lorsque lutilisateur sassoit droit et le dos de la chaise est droit, à une configuration essentiellement aplatie dans laquelle le dos de la chaise sincline vers larrière.
