Referring to FIGS. 1-5 and 20, the present disclosure provides a seat support 100a according to a first embodiment.

The seat support 100a includes a support member 1a, a first connecting member 2a and a second connecting member 3a. The support member 1a includes a support portion 11a and an anti-skid portion 12a. The support portion 11a is a sheet, the support portion 11a includes a back side 1101a and a front side 1102a, and the anti-skid portion 12a is arranged on the back side 1101a of the support portion 11a. The first connecting member 2a is fixedly connected with a first end (i.e. a front end) of the support portion 11a, and the first connecting member 2a and the first end of the support member 1a enclose a first connecting portion 24a. The second connecting member 3a is fixedly connected with a second end (i.e. a rear end) of the support portion 11a, and the second connecting member 3a and the second end enclose a second connecting portion 34a. In an embodiment, the anti-skid portion 12a is an anti-skid layer arranged on the back side 1102a, and the anti-skid layer 12a is made of an anti-skid material, such as silicone, rubber, nylon, and woven materials with rough surfaces.

The seat support 100a is connected with the seats of a vehicle, such as a car, a bus, a high-speed train, an airplane, and the like. A part of the seat support 100a is arranged on a seat cushion 2011 of the back seat assembly 201 and connected with a backrest 2013 of the back seat, and another part of the seat support 100a is connected with the front seat assembly 202. An area of the seat support 100a between the seat cushion 2011 and the front seat assembly 202 is regarded as a suspension portion 2012. User can sit on the seat cushion 2011 of the back seat assembly 201, and place legs and foot on the suspension portion 2012. In this way, user's legs are supported and the pressures on the legs are relieved, and the seat support 100a provides the user with a more comfortable seated position or a flat extended base for sleeping. The anti-skid portion 12a on the support member 1a can increase a friction between the support member 1a and the seat cushion 2011. Even if user continuously adjusts his sitting postures, the support member 1a can fit with the seat cushion 2011 orderly. The support portion 11a is a sheet, that is, the support portion 11a is thin, small in size and light in weight, so the seat support 100a can be easily carried when traveling.

Specifically, the first connecting member 2a is fixedly connected with the front seat assembly 202, and the second connecting member 3a is fixedly connected with the back seat assembly 201. In this way, the support member 1a is firmly connected between the back seat assembly 201 and the front seat assembly 202. It should be understood that the first connecting member 2a and the second connecting member 3a are both provided with an adjustment buckle (not labeled), lengths of the first connecting member 2a and the second connecting member 3a can be adjusted to adapt to the seats with different sizes, so the support member 1a is firmly connected between the back seat assembly 201 and the front seat assembly 202. Of course, the first connecting member 2a and the second connecting member 3a can further be elastic, and the sizes of the first connecting member 2a and the second connecting member 3a can further be adjusted.

The first connecting member 2a includes a covering portion 211a covering the support portion 11a, and at least a part of the covering portion 211a is not sewn with the support portion 11a, or the covering portion 211a is completely sewn with the support portion 11a; the covering portion 211a passes or extends through the support portion 11a, and the covering portion 211a is a one-piece structure.

The support member 1a is flatly laid between the front seat assembly 202 and back seat assembly 201, and the first connecting member 2a and the second connecting member 3a are used to fix the support member 1a. The first connecting member 2a is fixedly connected with the front seat assembly 202, and the second connecting member 3a is fixedly connected with the back seat assembly 201. In this way, the support member 1a can be stably arranged between the front seat assembly 202 and the back seat assembly 201, and the suspension portion 2012 of the support member 1a can support user's feet and the legs, thereby alleviating the acid swellings and numbness of the feet and the legs. The anti-skid portion 12a can increase the friction between the support portion 11a and the seat cushion 2011, so that the support portion 11a will not move under a movement of user.

Further, referring to FIGS. 1-2, the support portion 11a is made of flexible material. The support portion 11a includes an inner layer 111a and a surface layer 112a fixedly connected with the inner layer 111a. The anti-skid portion 12a is arranged on the inner layer 111a and protruded from an outer surface of the inner layer 111a. Specifically, a periphery of the inner layer 111a is fixedly connected with a periphery of the surface layer 112a. In one embodiment, areas of the inner layer 111a except the periphery are not separated from areas of the surface layer 112a except the periphery, that is, the inner layer 111a is completely fixedly with the surface layer 112a. In another embodiment, at least a portion of areas of the inner layer 111a except the periphery is fixedly connected with an area of the surface layer 112a except the periphery, that is, the inner layer 111a is not completely fixedly with the surface layer 112a. In a further embodiment, at least a portion of areas of the inner layer 111a except the periphery is separated from an area of the surface layer 112a except the periphery, that is, the inner layer 111a is not completely fixedly with the surface layer 112a.

In order to facilitate the storage and enhance user comfort, the support portion 11a is made of a flexible material. The support portion 11a is preferably made of a breathable flexible material, so it's very breathable for the user's hip, legs and feet. The support portion 11a has a double-layer structure, which is convenient to increase the thickness of the support portion 11a. So that, the user will not feel the presence of the anti-skid portion 12a when sitting on the support portion 11a. Further, it is further conducive to the setting of the anti-skid portion 12a on the thick support portion 11a. When the anti-skid portion 12a is made of plastic materials, the plastic materials are usually injected onto the inner layer 111a, and the inner layer 111a is set thinner, which can facilitate the attachment of plastic materials. It should be understood that in order to further increase the comfort of the support portion 11a, sponge or cotton can be filled between the inner layer 111a and the surface layer 112a.

Further, please referring to FIG. 2, the inner layer 111a is made of flexible material, such as cloth, fiber, paper cloth, velvet, polyurethane, PVC (Polyvinyl Chloride) flocking, etc. The periphery of the inner layer 111a is fixedly connected with the periphery of the surface layer 112a. The anti-skid portion 12a is arranged on the outer surface of the inner layer 111a. The inner layer 111a is also fixedly connected to a middle portion of the surface layer 112a.

The anti-skid portion 12a includes a plurality of anti-skid bumps 121a, which are arranged on the outer surface of the inner layer 111a. The anti-skid bump 121a is made of plastic, silicone, or rubber. The anti-skid bumps 121a are uniformly arranged on the back side; or the anti-skid bumps 121a are randomly arranged on the back side. The anti-skid bump 121a has a diameter of about 0-200 mm, for example, the anti-skid bump 121a has a diameter of 0.1 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 10 mm, 50 mm, 100 mm, 150 mm, or 200 mm. The anti-skid bump 121a has a height of about 0-20 mm, for example, the anti-skid bump 121a has a height of 0.1 mm, 0.2 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 5 mm, 10 mm, 15 mm, or 20 mm. A space between two adjacent anti-skid bumps 121a is about 0-200 mm, for example, the space between two adjacent anti-skid bumps 121a is 0.1 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 10 mm, 50 mm, 100 mm, 150 mm, or 200 mm. The anti-skid bumps 121a are arranged in a plurality of bump groups, diameters of bumps in each bump groups gradually decrease or increase in a direction from the back seat assembly 201 to the front seat assembly 202, or heights of bumps in each bump groups gradually decrease or increase in a direction from the back seat assembly 201 to the front seat assembly 202.

The cloth material has a good air permeability, and the anti-skid portion 12a can be quickly bonded with the inner layer 111a during injection molding. In order to ensure that the anti-skid portion 12a will not affect the comfort of the seat support 100a, the anti-skid portion 12a is set as a plurality of anti-skid bumps 121a, so that user can hardly feel the presences of the anti-skid bumps 121a even when he is sitting on the support portion 11a.

Further, a thickness of the surface layer 112a is greater than that of the inner layer 111a. The thinner inner layer 111a can facilitate a rapid prototyping of anti-skid bumps 121a, and the thicker surface layer 112a can reduce the presences of anti-skid bumps 121a.

Further, the inner layer 111a and the surface layer 112a are made of flexible material, such as cloth, fiber, paper cloth, polyurethane, PVC (Polyvinyl Chloride) flocking, etc., and the periphery of the inner layer 111a is sewn and fixedly connected with the periphery of the surface layer 112a. The cloth has a good air permeability. Both the surface layer 112a and the inner layer 111a are made of cloth, so the surface layer 112a and the inner layer 111a can be easily stored, carried and cleaned.

Further, both the first connecting member 2a and the second connecting member 3a are fixedly connected with the outer surface of the surface layer 112a of the support portion 11a, to prevent the first connecting member 2a and the second connecting member 2a from affecting the arrangement of the anti-skid portion 12a. In another embodiment, the first connecting member 2a or the second connecting member 3a can also be arranged on an inner surface of the surface layer 112a or an inner surface of the inner layer 111a. In a further embodiment, the first connecting member 2a or the second connecting member 3a can also be arranged on an outer surface of the inner layer 111a.

Further, referring to FIGS. 1 and 2, the first connecting member 2a includes a connecting belt 21a (which can be a long mesh belt) connected with the first end of the support portion 11a, a connecting part 22a (which can be a clamping seat), and a connecting part 23a (which can be a clamping head). A middle section of the connecting belt 21a is at least partially fixed with the support portion 11a, and both ends of the connecting belt 21a extend outside the support portion 11a. In an embodiment, a portion of the middle section of the connecting belt 21a is not fixed with the support portion 11a to form a handle (not labeled). One end of the connecting belt 21a is connected with the connecting part 22a, the other end is connected with the connecting part 23a. When the connecting part 22a is detachably connected with the connecting part 23a, the connecting belt 21a, the connecting part 22a, the connecting part 23a, the support portion 11a enclose the connecting portion 24a. The connecting belt 21a may be connected with the inner layer 111a or the surface layer 112a or connected between the inner layer 111a and the surface layer 112a.

The second connecting member 3a includes two connecting belts 31a (which can be medium length mesh belt), a connecting part 32a (which can be a clamping seat) and a connecting part 33a (which can be a clamping head). One end of each connecting belt 31a is fixedly connected with a corner at the second end of the support portion 11a, and the other end extends out of the support portion 11a. One of the two connecting belts 31a is fixedly connected with the connecting part 32a, the other one is fixedly connected with the connecting part 33a. When the connecting part 32a is clamped with the connecting part 33a, the two connecting belts 31a, the connecting part 32a, the connecting part 33a and the support portion 11a enclose the second connecting portion 34a.
