Abstract

Un soutien lombaire dynamique 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 est berçant lorsque lutilisateur transfère son poids vers larrière et vers lavant. 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 ou transfère son poids contre la chaise. Plus précisément, le support dorsal coussiné est adapté pour modifier sa forme dune forme convexe au repos, dans laquelle le bas du dos de lutilisateur est soutenu pour maintenir sa bonne posture lorsquil est assis droit et la chaise est en position droite, à une forme aplatie comprimée, dans laquelle le dos de lutilisateur est soutenu lorsquil se couche et que la chaise sincline vers larrière.
