Abstract

"ARMAçãO DE ENCOSTO DE CADEIRA, ENCOSTO DE CADEIRA, E, CADEIRA". Um encosto de cadeira perfilado inclui uma armação interna e uma externa afixadas entre si. A armação interna inclui uma superfície frontal tridimensionalmente curvada e uma superfície posterior bidimensionalmente curvada. A armação interna pode incluir uma nervura interna adjacente ao topo da armação que é configurada diferentemente da borda superior da armação interna. A nervura interna é adaptada para permitir que a armação interna seja cortada adjacente a esta nervura interna de modo que a dita armação interna pode ter sua forma variada. A armação também pode incluir endentações no lado posterior da armação adjacente aos cantos da armação interna. As endentações são dimensionadas para receber tecido superposto o qual é puxado em volta dos cantos de tal modo que o tecido no dorso da carcaça adjacente aos cantos não se projeta para fora mais do que tecido em qualquer ponto, a despeito da superposição do tecido nos cantos. A armação interna pode também incluir uma pluralidade de furos univocamente identificados adaptados para permitir que uma variedade de diferentes ornamentações seja fixada à armação interna.
