The structure comprises a backrest or occupant supporting member (2) that intersects with and is attached to a countersupporting member (4) in a manner that results in each bearing on the other. Armrests (A.P.) are disclosed as an integral part of the countersupporting member (4). The backrest member (2) is disclosed as straight, with a convex curve in the lower portion (L.P.) thereof to support an occupant's lumbar curve, with a bend between the upper and lower portion to orient the upper portion (U.P.) of the chair at a higher angle than the lower portion. A variety of methods of attaching the backrest member to the countersupporting member are disclosed, as are a number of ways of securing the leisure chair in an open position. Other embodiments are disclosed with a seat and legrest structure (3) attached to the occupant supporting member, and upholstery (12, 14 and 16) supported on the chair.
La présente invention concerne une structure comprenant un dossier ou élément (2) supportant l'occupant. Cet élément croise un organe d'appui (4), l'élément et l'organe d'appui étant fixés entre eux de façon à se soutenir mutuellement l'un sur l'autre. Des accoudoirs (AP) sont intégrés à l'organe d'appui (4). Le dossier (2), de forme droite, comporte une partie inférieure (LP) présentant un galbe convexe permettant de soutenir la cambrure lombaire de l'occupant. Une courbure entre la partie supérieure et la partie inférieure fait que la partie supérieure (UP) de la chaise présente une inclinaison plus relevée que la partie inférieure. L'invention concerne également divers procédés de fixation du dossier avec l'organe d'appui. L'invention concerne aussi plusieurs façons d'assurer le maintien de la chaise de loisirs en position ouverte. D'autres réalisations concernent un siège pourvu d'une structure de repose-jambes (3) fixée sur l'élément d'appui de l'occupant, ainsi qu'un rembourrage (12, 14, 16) monté sur la chaise.
