Patent

CA 2653912

The invention relates to a back rest for a stool or a chair, comprising two adjacent, spring-mounted back supports (3.1), each of which is fixed to a separate carrier part (4.1). Said back rest is characterised in that each carrier part (4.1) forms the first limb of an essentially L-shaped carrier (4), and the second limb (4.2) of each carrier (4) is fixed beneath the stool or chair seat in such a way that it can be pivoted about a horizontal axis against an elastic force.

L'invention concerne un dossier destiné à une chaise ou à un fauteuil, comportant deux appuis dorsaux (3.1) disposés l'un à côté de l'autre, maintenus de façon élastique, chaque appui étant fixé à une partie support séparée (4.1). Le dossier selon l'invention est caractérisé en ce que chaque partie support (4.1) forme le premier membre d'un support (4) essentiellement en forme de L, et en ce que le deuxième membre (4.2) de chaque support (4) est fixé de manière à pivoter autour d'un axe horizontal contre une force ressort, en dessous de l'assise de la chaise ou du fauteuil.
