Abstract

Ce siège pliant (1) est constitué par deux éléments de structure (2 et 3) articulés l’un par rapport à l’autre selon un axe d'articulation principal (A) réalisé par une charnière principale (5) composée en deux parties (51 et 52). Chaque élément de structure (2 ou 3) comporte deux montants (20 ou 30) disposés en vis-à-vis. Une bande textile (4) relie les montants (20 ou 30) au niveau de leur extrémité (200 ou 300) opposée à l'axe d'articulation principal (A) pour constituer une zone formant assise (41) et une zone formant dossier (42).Selon l'invention, chaque partie (51 ou 52) de la charnière principale (5) supporte deux axes d'articulation secondaires (B) disposés en vis-à-vis. Un montant (20 ou 30) est relié à un axe d'articulation secondaires (B) et à un axe d'articulation tertiaire (C) reliant une biellette (8) articulée à l'autre biellette (8) par un axe d'articulation quaternaire (D) parallèle aux axes d'articulation secondaire (B) et tertiaire (C). Le siège (1) étant déplié, les deux parties (61 et 62) d'une charnière secondaire (6) comportent chacune une butée venant en contact l'une contre l'autre. Un moyen de blocage (81) relie les extrémités des biellettes (8) et maintient fixement la position des biellettes (8) d'un même élément de structure (2 ou 3).Un tel siège est particulièrement compact en position pliée, tout en offrant un confort d'utilisation optimal et une résistance mécanique performante en utilisant peu de matière première. Figure à publier avec l’abrégé : Fig. 1This folding seat (1) consists of two structural elements (2 and 3) articulated with respect to one another along a main articulation axis (A) produced by a main hinge (5) composed of two parts (51 and 52). Each structural element (2 or 3) comprises two uprights (20 or 30) arranged vis-à-vis. A textile band (4) connects the uprights (20 or 30) at their end (200 or 300) opposite to the main articulation axis (A) to constitute a zone forming a seat (41) and a zone forming a backrest (42) .According to the invention, each part (51 or 52) of the main hinge (5) supports two secondary articulation axes (B) arranged vis-à-vis. An upright (20 or 30) is connected to a secondary articulation axis (B) and to a tertiary articulation axis (C) connecting a link (8) articulated to the other link (8) by an axis of quaternary joint (D) parallel to the secondary (B) and tertiary (C) joint axes. The seat (1) being unfolded, the two parts (61 and 62) of a secondary hinge (6) each comprise a stop coming into contact with one another. A locking means (81) connects the ends of the links (8) and fixedly maintains the position of the links (8) of the same structural element (2 or 3). Such a seat is particularly compact in the folded position, while offering optimal comfort of use and high-performance mechanical resistance using little raw material.
