Elastic assembly of chair cushion

Abstract

An elastic assembly of a chair cushion comprises a hollowed frame, a plate body located within the hollowed frame and a plurality of elastic connecting strips connected between the frame and the plate body. One end of each elastic connecting strip is connected to the plate body and another end of the elastic connecting strip is connected to the frame. The elastic connecting strip is folded as several folds. Each bending portion of each elastic connecting strip is formed as a cambered arc without any sharp angle. The frame, plate body and plurality of elastic connecting strips are integrally formed as an elastic assembly is then assembled to a chair.
