Abstract

trata-se de um sistema de articulação (1) para cadeiras, sendo que o sistema compreende uma armação principal (2); um suporte para um assento (4) montado na armação principal; um elemento de articulação (8) articulado à armação principal (2), de modo que o mesmo possa girar sobre um eixo geométrico de rotação (9), em que o suporte para o assento (4) é articulado ao elemento de articulação (8) em um primeiro ponto de dobradiça (10) e em um deslizador (12) em um segundo ponto de dobradiça (11) localizado na fronte do suporte para o assento, sendo que o deslizador (12) pode deslizar ao longo de uma guia (13) solidamente limitada à armação principal; um suporte para um encosto (5) acoplado ao elemento de articulação (8), em que, em um plano de referência perpendicular ao eixo geométrico de rotação (9), a guia (13) determina uma trajetória para o segundo ponto de dobradiça (11 ), sendo que a dita trajetória tem pelo menos uma seção de trajetória (14) que é retilínea ou curvilínea com a concavidade voltada na direção oposta ao eixo geométrico de rotação 9.it is a chair articulation system (1), the system comprising a main frame (2); a seat support (4) mounted to the main frame; a hinge element (8) hinged to the main frame (2) so that it can rotate about a geometric axis of rotation (9), wherein the seat support (4) is hinged to the hinge element (8 ) at a first hinge point (10) and a slider (12) at a second hinge point (11) located on the front of the seat support, with the slider (12) sliding along a guide ( 13) solidly limited to the main frame; a support for a backrest (5) coupled to the pivot element (8), wherein, in a reference plane perpendicular to the axis of rotation (9), the guide (13) determines a path for the second hinge point ( 11), wherein said path has at least one path section (14) which is straight or curvilinear with the concavity facing away from the geometric axis of rotation 9.
