EMBODIMENTS

In order to make the purpose, technical solution, and technical effects of the present invention clearer, the following will further explain the present invention in conjunction with embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit it.

Referring to FIGS. 1, 2, 5-7, an elastic cushion includes two connecting rods 1, a plurality of elastic arc-shaped rods 2, and at least two flexible bearing members 3a, 3b arranged an upper and a lower. The two connecting rods 1 are arranged in parallel. The plurality of elastic arc-shaped rods 2 are arranged side by side, and two ends of each of the elastic arc-shaped rods 2 are respectively connected to two connecting rods 1. Opposite side edges of each of the flexible bearing members 3a, 3b are respectively connected to the two connecting rods 1 and tension, and a cavity 4 is formed between adjacent two of the flexible bearing members 3a, 3b.

The elastic cushion can be used as a seat cushion, backrest cushion, etc. The user's buttocks or back exerts pressure on the flexible bearing member 3a at the topmost, and the flexible bearing member 3a at the topmost is subjected to the pressure to generate adaptive concave deformation of the shape of the user's buttocks or back in the direction of the elastic arc-shaped rods 2, and a tensile force is applied to the two connecting rods 1 to promote the deformation of the elastic arc-shaped rods 2. When the user leaves the elastic cushion, the elastic arc-shaped rods 2 reset, the flexible bearing member 3a at the most are also restored to a tensioned state. When the user seats or or leans on the elastic cushion, only the flexible bearing member 3a at the topmost is contacted, and the air can flow smoothly in the cavity 4, so that the elastic cushion has excellent ventilation and breathability, facilitating the timely removal of odors and sweat, and avoiding skin diseases.

The flexible bearing member can also be set as a single layer, the opposite side edges of the flexible bearing member 3a are wound around the two connecting rods 1. However, compared with the single layer of the flexible bearing member, the double lawyers of the flexible bearing member have a greater deformation amplitude and is more prone to deformation, thereby giving the user a softer and more comfortable feeling. In addition, the term “tension” means that the flexible bearing member has a moderate tightness, which is easy to deform and does not come into contact with the elastic arc-shaped rods 2. If the flexible bearing member is too loose, when the user's back or buttocks come into contact with the flexible bearing member, the flexible bearing member may touch the elastic arc-shaped rods 2, causing discomfort. If the flexible bearing member are too tight, when the user's back or buttocks contact with the flexible bearing member 3, the user will feel very hard and uncomfortable.

It should be understood that the elasticity of the elastic arc-shaped rods 2 depends on its material and diameter, which can be spring steel, aluminum alloy, glass fiber, stainless steel, etc., preferably aviation aluminum and glass fiber. The diameters of the elastic arc-shaped rods 2 are set according to its material and the user's needs, preferably 0.1 cm-10 cm.

The flexible bearing members 3a, 3b are made of cotton cloth, polyester fiber, nylon, high-density polyethylene fiber, and other materials.

Referring to FIGS. 2-4, in an embodiment, the two connecting rods 1 are respectively provided with multiple pairs of plug-in cylinders 5, and the two ends of each of the elastic arc-shaped rods 2 are respectively inserted into one pair of plug-in cylinders 5 on the two connecting rods 1. The plug-in cylinders 5 match with the two ends of each of the elastic arc-shaped rods 2. The purpose of setting the plug-in cylinders 5 is to facilitate the disassembly and assembly of the elastic arc-shaped rods 2 and to save assembly time. Especially, when a certain elastic arc-shaped rod 2 is broken or needs to be replaced, disassembly and assembly are very convenient.

Referring to FIG. 3 and FIG. 4, in an embodiment, multiple pairs of plug-in cylinders 5 extend laterally from the opposite sides of the two connecting rods 1 and form arc-shaped gentle slopes 6. The vertical distance between each of the arc-shaped gentle slopes 6 and each of the two connecting rods 1 thereon is preferably 1-5 cm. The arc-shaped gentle slopes 6 prevent the user's buttocks or back near the connecting rods 1 from contacting with the elastic arc-shaped rods.

Referring to FIG. 4, in an embodiment, the elastic cushion further includes two connecting boards 7, each connecting with the plug-in cylinders 5 on one of the two connecting rods 5 to form a plane. When the elastic cushion is put on car seats, sofas, and office seats, etc., the connecting boards 7 can prevent the plug-in cylinders 5 from squeezing the surface of car seats, sofas, and office seats, causing deformation or even breaking the surface.

Referring to FIG. 1 and FIG. 6, in an embodiment, a covering part 8 extends from the front side and the rear side of the flexible bearing members 3a at the topmost, respectively, and the covering part 8 covers the elastic arc rods 2 at the outermost, and the joint between the elastic arc rods 2 at the outermost and the two connecting rods 1, thereby making the elastic cushion beautify and increasing its decorative properties.

The flexible bearing members arranged on the upper and lower have multiple setting methods.

Referring to FIG. 2 and FIG. 6, in an embodiment, the plug-in cylinders 5 or the elastic arc-shaped rods 2 pass through the flexible bearing member 3b in the lower, so that the flexible bearing member 3b in the lower is partially located between the flexible bearing member 3a in the upper and the elastic arc-shaped rods 2.

Referring to FIG. 5, in the other embodiment, the elastic cushion has two of the flexible bearing members 3; the two connecting rods 1 are respectively provided a support member 9; the left and right sides of the flexible bearing member 3 at the upper are respectively wound around one of the two connecting rods 1 and the support member 9 thereon; the flexible bearing member 3b at the lower passes through the joint between the support member 9 and the two connecting rods 1 and is wound around the two connecting rods 1.

Referring to FIG. 7, in the other embodiment, the side edges of the flexible bearing members 3a, 3b at the upper and the lower are connected as a whole to form the cavity 4, and the two connecting rods 1 and the elastic arc-shape rods 2 are wrapped in the cavity 4.

Referring to FIG. 5, in the other embodiment, the front and rear sides of the flexible bearing member 3a at the topmost are respectively equipped with a front covering part 10 and a rear covering part 11, covering the elastic arc-shaped rods 2, thereby making the elastic cushion beatify and increasing its decorative properties.

Referring to FIG. 7, in the other embodiment, the front covering part 10 and/or the rear covering part 110 are provided with an opening 12. From the opening, not only the usage status of the elastic arc-shaped rods 2 can be observed, which is convenient for timely detection and replacement of the damaged elastic arc-shaped rods 2, but also other objects, such as sachets, herbal bags, etc., can be placed into the cavity 4 through the opening 12.
