Integrated dual-layer spring cushion

Abstract

The invention discloses an integrated dual-layer spring cushion. The integrated dual-layer spring cushion comprises first cloth, second cloth, third cloth and multiple groups of springs, wherein multiple transverse seams are formed among the first cloth, the second cloth and the third cloth, the first cloth and the second cloth are mutually separated and folded to form multiple corresponding vertical seams, a plurality of first independent cloth bags are continuously formed between the third cloth and gaps between the adjacent vertical seams in the first cloth, and a plurality of second independent cloth bags are continuously formed between the third cloth and gaps between the adjacent vertical seams in the second cloth; and each group of springs comprises two springs correspondingly packaged in the first independent cloth bag and the second independent cloth bag in a lamination state. According to the integrated dual-layer spring cushion, a traditional structural form of a spring cushion of adhering through glue is abandoned, and the glue adhesion manner is not adopted, so that the problem of the traditional spring cushion that adhering joints are broken after long-term use is avoided, and the stability of the spring cushion is higher.

Description

technical field [0001] The invention relates to the technical field of pocket spring cushions, in particular to a double-layer pocket spring cushion. Background technique [0002] Pocket springs are formed by compressing and encapsulating a single spring in a cloth bag. The pocket springs are connected in turn to form a pocket spring string, and the pocket spring strings are arranged and bonded to form a whole to form a spring pad. The spring cushion of this kind of structure, because each spring is independently wrapped and packaged, each spring has a certain degree of independence, and each spring can flex independently without affecting the adjacent springs, in order to meet consumers' requirements for mattress softness At present, there are spring pads with upper and lower two-layer structures. The spring pads of this structure are directly bonded and combined with two independent single-layer spring pads by adhesive. [0003] However, the spring pad of this kind of str...

AI Technical Summary

Problems solved by technology

[0003] However, the spring pad of this kind of structure has the following defects: since the upper and lower layers of the spring pad are bonded together with glue, a large amount of glue needs to be used, not only the production process is complicated and the production cost is high; and, after long-term use, The bonding performance of the bonding glue will decrease over time, and the bonding is prone to breakage, which will affect the structural stability of the entire pocket spring pad
