POSTURIZED CONTINUOUS MATTRESS SPRING CORE

摘要

A spring interior (12) of a mattress (10) comprising a plurality of longitudinally extending bands of springs (18) disposed side by side and connected together with helical lacing wires (24) in the top and bottom faces (34, 36) of the bands. Each band of springs (18) comprises a single length of wire formed into a plurality of coil springs (20) interconnected by innerconnecting segments (38, 40) located alternatively in the top and bottom faces (34, 36) of the bands. The spring interior (12) is characterized by longitudinally extending sections (54) of differing firmnesses throughout the length of the spring interior. The different firmnesses in the different sections (54) of the spring interior (12) are attributable to different configurations of the innerconnecting segments (38, 40). The innerconnecting segments (38, 40) within the firmer sections of the mattress have a deeper V-shaped indentation (52) than the portions of the bands of springs in the less firm sections of the mattress.
