Title: POCKETED SPRING ASSEMBLY COMPRISING STRINGS OF SPRINGS WITH TABS
Abstract:
A pocketed spring assembly (12, 1 2', 1 2a, 12d, 1 1 2, 212, 31 2, 412, 412', 512, 612) comprises a plurality of parallel strings of springs (26, 26a, 26', 126, 226) held together with tabs (50, 60, 250, 260). Longitudinal seams (78) joining overlapping tabs (50, 60, 250, 260) extend generally the same direction as the strings of springs (26, 26a, 26', 1 26, 226). Pockets (80, 280) are formed along a string of springs (26, 26a, 26', 1 26, 226) by aligned separating seams (82, 84, 282, 284). At least one spring (38) is positioned in each pocket (80, 280). Each separating seam (82, 84, 282, 284) joins opposed plies of the string and keeps the spring (38) in its pocket (80, 280). Ends of aligned separating seams (82, 84, 282, 284) are spaced from each other, thereby improving airflow between pockets (80, 280).
