Abstract

Una struttura a guscio in cui una porzione di fondo è integrata con una porzione o parte di uno schienale. Le porzioni di fondo e di schienale hanno elasticità e sono tali da adattarsi ai loro componenti e tali componenti operano in un intervallo diverso tra loro. La struttura a guscio supporta a deflessione di un elemento a schienale un carico leggero, mentre un carico pesante applicato da una persona allo schienale è supportato da oscillazione di barre di supporto posteriori. Nella struttura a guscio una porzione di fondo supporta una piastra di fondo ed una porzione per collegare quest'ultima alla struttura a guscio per lo schienale e quest'ultime sono integrate con il medesimo materiale da una porzione di collegamento. Due o più fessure parallele sono formate in una porzione di demarcazione tra le porzioni e le varie porzioni presentano curvature differenziate. Tacche laterali collegate alle fessure di estremità si estendono verso i bordi opposti della porzione di fondo e porzioni ripiegate a gola si intersecano con le tacche formate sui bordi della porzione di fondo. La struttura a guscio presenta una porzione anteriore adattabile alla sagoma dello schienale.
