Title:
INTEGRATED MULTI-LAYERED POCKET SPRING GROUP CONFIGURED TO CHANGE GRADUALLY AT INTERVALS
Document Type and Number:
WIPO Patent Application WO/2018/049780
Kind Code:
A1
Abstract:
An integrated multi-layered pocket spring group configured to change gradually at intervals comprises: multiple continuous and independent accommodation cavities formed of a fabric (1); and spring sets (2) enclosed in the respective accommodation cavities. The fabric (1) has at least one curved separation seam dividing the respective accommodation cavities into at least two layers of independent accommodation cavities (12). The curved separation seam continuously curves such that the independent cavities adjacent in a horizontal direction have different heights. Respective springs of each spring group are independently enclosed in the independent cavities adjacent in a vertical direction. Being enclosed in the independent cavities (12) having different heights, the respective springs have different initial compression amounts, such that respective regions of a pocket spring group have different degrees of softness. In the invention, the pocket spring group continuously and smoothly changes in softness according to the curvature of the spine, thereby ensuring good support, and fitting the profile of the spinal curve. A mattress made of the pocket spring group of the invention is highly comfortable.
