Patent

CA 2389356

An office chair has a back with a central portion and respective wings or bolsters on opposite sides of the central portion. The wings are coupled to the main central portion by arm structures that are designed to allow the wings to flex rearwardly from a rest position and back to the rest position in response to forces exerted by a person seated in the chair, but to resist forces tending to move the wings forwardly from the rest position.

La présente invention concerne une chaise de bureau ayant un dossier comportant un partie centrale et des parties latérales ou traverses respectives se trouvant de chaque côté de la partie centrale. Les parties latérales sont fixées à la partie centrale principale par des structures à bras qui sont conçues pour permettre aux parties latérales d'être fléchies vers l'arrière à partir d'une position de repos et de revenir à la position de repos en réponse à des forces exercées par une personne assise sur la chaise, mais ne leur permettant pas de résister aux forces tendant à fléchir les parties latérales vers l'avant à partir de la position de repos.
