发明名称 COIL SPRING ASSEMBLIES FOR FURNITURE
摘要 Disclosed herein is a furniture spring assembly including a planar wire mesh base that defines an array of nests each of which accommodate a conventional coiled spring with a uniformly curved end loop. Each of the nests include retaining portions which receive the resilient end loops of the coiled springs only after deformation thereof and thereafter permit the loops to nest by springing back into their original shape. Once nested, the end loops are restrained by the retaining portions from movement in all directions establishing a stable unit.
