DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

[0028] An elastic cushion 10 of Embodiment 1 is shown in FIGS. 1-4. The elastic cushion 10 comprises a spring module (i.e., an elastic module) 2, and the spring module 2 comprises springs 21 and a flexible band (e.g., webbing 3). Two adjacent rows of the springs 21 define a staggered arrangement. The springs 21 are wrapped by cloth sleeves 22, or the springs 21 are independent springs pocketed in bags. Preferably, the springs 21 are anti-waisted drum springs (i.e., waist-shaped springs). That is, diameters of waists of the springs 21 are smaller than diameters of ends of the springs 21 (e.g., small than diameters of at least one end of each of the springs 21). Middle parts (i.e., waists) of the springs 21 comprise fixing seats 6, and the springs 21 of the spring module 2 are arranged as shown in FIGS. 5A, 5B, and 5C. Referring to FIG. 6, a series connection of the webbing 3 is as follows: the springs 21 contact or are close to one another to be arranged in rows in a lateral direction, two adjacent rows of the rows are staggered, and at least two opposing sides of the fixing seats 6 comprise perforations 61. The two adjacent rows of the springs are staggered to enable the perforations 61 in the fixing seats 6 to be connected in series to form a substantially continuous straight line 62. The webbing 3 passes through the perforations 61 in the substantially continuous straight line 62, and two ends of the webbing 3 comprise stoppers 5 or buckles, so that the two adjacent rows of the springs 21 are connected in series. In this way, the webbing 3 connects the springs 21 of the two adjacent rows of the springs 21 in series, so that compressed springs 21 in a first row of the two adjacent rows and uncompressed springs 21 in a second row of the two adjacent rows are forced in series without creating large gaps. Preferably, first ends of the stoppers 5 are configured to be fixed to the webbing 3, and second ends of the stoppers 5 are configured to be detachably fixed to the webbing 3.

[0029] A bottom side of the spring module 2 can be fixed on a rigid or flexible base plate 20.

[0030] The fixing seats 6 comprises a stop structure 63. The stop structure 63 cooperates with the stoppers 5 of the webbing 3 to fix the webbing 3, and an outside of the two ends of the webbing 3 comprise stop positions 31 for receiving the stoppers 5.

[0031] An elastic mattress (i.e., spring mattress) made of the spring module 2 is shown in FIG. 1. The elastic mattress comprises a top layer 1 and a peripheral fixing webbing 4, and the peripheral fixing webbing 4 loops an outer periphery of the spring module 2 together. The top layer 1 comprises side edges 11, and the side edges 11 can be snapped to the fixing seats 6 of the springs 21 or the rigid or flexible base plate 20 of the spring module 2.

Embodiment 2

[0032] Referring to FIG. 7, this embodiment differs from Embodiment 1 in that the two adjacent rows of the springs 21 in the spring module 2 are respectively aligned with each other, a single row of the two adjacent rows of the springs 21 are connected in series using the webbing 3, and the fixing seats 6 of the two adjacent rows of the springs 21 are snapped together or connected by a third piece. In this way, the single row of the two adjacent rows of the springs 21 are connected in series by the webbing 3, and different rows of the two adjacent rows of the springs 21 are connected by the fixing seats 6. The springs 21 deform independently while obstructing each other without moving away from each other.

[0033] An arrangement of the springs 21 and connectors of Embodiments 1-2 do not limit the spring module 2 and the elastic cushion 10 made therefrom of the present disclosure, and the spring module 2 can be made using other arrangements by a person of skill in the art. The connectors are not limited to only those specified in Embodiments 1-2, and the present disclosure covers any modifications and variations of the presently presented embodiments provided the springs 21 are connected by the flexible band. The elastic cushion 10 can be made using the spring module 2 in various ways as well.
