Title (EN) POCKETED SPRING ASSEMBLY HAVING MULTI-LAYERED IMPERMEABLE FABRIC
(FR) ENSEMBLE RESSORT ENSACHÉ AYANT UN TISSU IMPERMEABLE MULTICOUCHE
Abstract:
(EN) A pocketed spring assembly (12, 12a, 12b, 12d, 12e, 12f, 12g) comprises a plurality of parallel strings (26b) of individually pocketed springs (28). Each string (26b) is joined to at least one adjacent string. Each string (26b) has first and second opposed plies (48, 50) of fabric and a plurality of pockets (38, 38') formed along a length of the string by transverse segmented seams (54, 54') joining the plies. Gaps (66, 66', 70, 70') between the segments of the seams (52, 52', 54, 54') allow air to pass into and out of the pockets (38, 38') despite the fabric being impermeable to airflow through the fabric. The fabric has at least four layers (76, 80, 78, 76). The size of the gaps (66, 66', 70, 70') determines the firmness or "feel" of the pocketed spring assembly (12, 12a, 12b, 12d, 1 2e, 12f, 12g) or portion thereof.
(FR) L'invention concerne un ensemble à ressorts ensachés (12, 12a, 12b, 12d, 12e, 12f, 12g), qui comprend une pluralité de suites parallèles (26b) de ressorts ensachés individuellement (28). Chaque suite (26b) est reliée à au moins une suite adjacente. Chaque suite (26) comprend des premier et second plis (48, 50) de tissu opposés et une pluralité de sachets (38) formés le long d'une longueur de la suite par des coutures segmentées transversales (54) reliant les plis (48, 50). Des intervalles (66, 66', 70, 70') entre les segments des coutures (52, 52', 54, 54') permettent à l'air de passer à l'intérieur et hors des sachets (38, 38') même si le tissu est imperméable à l'écoulement d'air à travers le tissu. Le tissu comporte au moins quatre couches (76, 80,78, 76). La taille des intervalles (66, 66', 70, 70') détermine la fermeté ou "toucher-ressenti" de l'ensemble à ressorts ensachés (12, 12a, 12b, 12d, 12e, 12f, 12g) ou d'une partie de celui-ci.
