The rest part (51) of the backrest (5) is supported by two front legs (1, 1') projecting through a horizontal cross-tube (3). The seat plate (4) is placed on the cross-tube (3) by means of brackets which are fixed or which can pivot around a main axis (D). Elastic bridge pieces (500, 500') are inserted between the rest part (51) and the rest element (10, 10'), and the rest part (51) is also elastic. In an alternative embodiment, the rest part (51) and the bridge pieces (500, 500') construct a component part. The chair can be completed with armrests (8, 8') which can be inserted into the cross-tube (3). The arm supports (82, 82') of said armrests can horizontally pivot in order to stack a number of chairs next to one another. In a completely equipped embodiment, a pivotal side table (9) is eccentrically arranged on an armrest (8) and comprises a tilt-swivel mechanism and means for safeguarding against overstressing. The side table (9) falls into the vertical non-use position when overstressed. Coupling elements are provided on both sides of the cross- tube (3) for forming rows of interconnected chairs.

L'élément dossier (51) du dossier (5) est porté par deux pieds avant (1, 1') traversant un tube transversal horizontal (3). L'assise (4) est posée sur le tube transversal (3) au moyen d'équerres fixes ou tournant autour de l'axe principal (D). Des pièces intermédiaires (500, 500') élastiques sont placées entre l'élément dossier (51) et la partie dossier (10, 10'). La partie dossier (51) est également élastique. En variante, la partie dossier (51) et les pièces intermédiaires (500, 500') peuvent être conçues d'une seule pièce. Le siège être complété par des accoudoirs (8, 8') insérés dans le tube transversal (3). Les repose avant-bras (82, 82') pivotent horizontalement, ce qui permet d'empiler plusieurs sièges. Dans la version comportant un équipement complet, un accoudoir (8) est pourvu d'une tablette latérale (9) pivotante et excentrique qui possède un mécanisme de pivotement et un dispositif de protection contre les surcharges. Lorsque ce dispositif est sollicité, la tablette latérale (9) tombe en position de repos. Les éléments d'accouplement de chaque côté du tube transversal (3) permettent de former des rangées de sièges reliés entre eux.
