Abstract

"CADEIRA, E, CONSTRUçãO DE ENCOSTO PARA UMA CADEIRA". Uma cadeira (20) inclui uma base (21), um assento (22) suportado operacionalmente na base para realizar o ajuste de profundidade, e um encosto (23) suportado operacionalmente por uma parte reta (24) que se estende a partir da base para reclinar. O encosto inclui um suporte de encosto estrutural (25), uma cobertura traseira (26) que cobre um lado traseiro do suporte de encosto, e uma cobertura cóncava dianteira/inferior (27) que cobre a parte reta entre uma parte traseira do assento e abaixo do suporte de encosto para fornecer uma aparência de encosto e assento de peça única. A cobertura cóncava define uma concavidade (28) formada para receber uma parte traseira (29) do assento para facilitar o ajuste de profundidade, mas de forma que a aparência de encosto e assento de peça única seja mantida. A cobertura cóncava inclui adicionalmente a extensão ascendente das ling³etas (94) que engatam um lado dianteiro do encosto, e inclui uma parte inferior que enrola em torno da borda marginal inferior e em uma superfície traseira do suporte de encosto, e a cobertura cóncava inclui um flange voltado para cima (90) que se sobrepõe à borda marginal inferior do suporte de encosto para travar a parte inferior contra a borda marginal inferior. Um suporte de lombar verticalmente ajustável (56) é montado de forma operacional no suporte de encosto para realizar o movimento vertical, e alças (82) são fornecidas para mover ao longo das bordas laterais verticais do encosto ao longo de um caminho que é não paralelo ao caminho vertical do suporte de lombar.
