[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0038] In the present invention, unless otherwise specified, directional words such as "up, down, front, back, left, right" generally refer to directions in the state of installation and use.

[0039] On the one hand, the present invention provides a seat cushion, which includes a mounting seat 1, a support seat 2 connected to the top of the mounting seat 1, and an elastic pad 3 fixedly supported above the support seat 2, the support seat 2 can rotate relative to the mounting seat 1 to ensure that the elastic pad 3 provides balanced support to the buttocks, the elastic pad 3 includes a first pad body 31 and a second pad body 32 stacked up and down, and the second pad body 32 is configured to cooperate with the first pad body 31 and the support seat 2 to adjust the supporting force around the buttocks to relax the human body.

[0040] In the present invention, it should be noted that the buttocks should be understood as the part that contacts the cushion when a person sits, and it can include the part from the back of the buttocks to the thigh. In addition, the size of the elastic pad 3 should be understood to be able to cover the entire buttocks.

[0041] The seat cushion of the present invention is configured such that the support seat 2 can rotate relative to the mounting seat 1. When the human body changes its sitting posture, the center of gravity will change (for example, the center of gravity moves forward, backward, leftward, rightward, etc.), thereby generating different pressures on various parts of the elastic pad 3. Since the elastic pad 3 is fixedly supported on the support seat 2 and can rotate together with the support seat 2, the elastic pad 3 can rotate according to the different pressures received, thereby flexibly adapting to the changes in the sitting posture of the human body, ensuring that the elastic pad 3 is always in balanced contact and support with the buttocks, maintaining uniform force between the buttocks and the seat cushion, and reducing local excessive pressure. Furthermore, the present invention designs the elastic pad 3 as a layered structure, so that the elastic pad 3 includes a first pad body 31 and a second pad body 32 stacked up and down, and the second pad body 32 cooperates with the first pad body 31 and the support seat 2. According to ergonomics (such as according to the curves and force sensitivity of the human leg and thigh root), the local force on the buttocks is adjusted (for example, the support on the front side of the buttocks is weakened, and the support on the back side of the buttocks and the left and right sides is strengthened), which can promote the human body to relax, thereby effectively alleviating the discomfort caused by long-term poor sitting posture.

[0042] In the present invention, the elastic pad 3 can have a variety of contour shapes, such as square, circular, elliptical, etc. When the elastic pad 3 is circular, the upper surface of the first pad body 31 can be set as a spherical surface, and the lower surface can be set as a plane, so that the second pad body 32 has the same circular contour as the first pad body 31, and the second pad body 32 includes a main body in the shape of a circular plate and an annular boss protruding downward from the lower surface of the main body along the periphery of the main body, thereby keeping the hips high and the legs low, and the lower annular boss can strengthen the support for the periphery of the hips, thereby promoting the relaxation of the human body. Among them, the thickness of the first pad body 31 can be set to 1-5cm, the thickness of the main body can be set to 2-5cm, and the height of the annular boss can be set to 1-5cm.

[0043] A preferred embodiment of the present invention will be described in detail below, the elastic pad 3 is square, the first pad body 31 and the second pad body 32 are square plates, and the support seat 2 correspondingly has a square support surface for supporting the elastic pad 3. It can be understood that the support seat 2 can have any shape as long as the surface in contact with the elastic pad 3 is square.

[0044] In the above description, it should be noted that the square plate shape of the first pad 31 and the second pad 32 should be understood as the first pad 31 and the second pad 32 having a certain thickness and having parallel front and rear sides, and parallel left and right sides (see Figure 1-Figure 4 ), does not exclude the first pad body 31 and the second pad body 32 from being deformed within their respective square outlines, such as will be described later.

[0045] Specifically, according to one embodiment of the present invention, Figure 7 and Figure 8 As shown, the front side of the first cushion body 31 extends out of the front side of the second cushion body 32, and the front side of the square support surface is located between the front side of the first cushion body 31 and the front side of the second cushion body 32 in the horizontal direction. Through the above arrangement, that is, through the cooperation of the second cushion body 32 with the front side of the first cushion body 31 and the support seat 2, the support of the thigh (i.e., the part where the buttocks contact the front side of the elastic cushion) by the seat cushion can be gradually reduced, reducing the force on the thigh and promoting the relaxation of the thigh.

[0046] Preferably, a distance L1 between the front side of the first cushion body 31 and the front side of the second cushion body 32 is 2.2-10.5 cm, and a distance L2 between the front side of the first cushion body 31 and the front side of the square support surface is 2-10 cm.

[0047] According to another embodiment of the present invention, Figure 7 and Figure 8 As shown, the rear side of the second pad 32 extends out of the rear side of the square support surface, and the rear side of the first pad 31 extends out of the rear side of the second pad 32. Through the above arrangement, that is, through the cooperation of the second pad 32 with the first pad 31 and the rear side of the support seat 2, the support for the rear side of the buttocks can be enhanced to improve comfort.

[0048] Preferably, a distance L3 between the rear side of the first pad body 31 and the rear side of the second pad body 32 is 2-10 cm, and a distance L4 between the rear side of the first pad body 31 and the rear side of the square support surface is 1.5-9.8 cm.

[0049] According to another embodiment of the present invention, Figure 5 and Figure 6 As shown, the second cushion body 32 may include a middle cushion block 321 located in the middle and two side cushion blocks located on the left and right sides of the middle cushion block 321, respectively. The side cushion blocks include a first side cushion block 322 and a second side cushion block 323 arranged at intervals along the front-to-back direction of the seat cushion. The middle cushion block 321, the first side cushion block 322 and the second side cushion block 323 are all square bodies. The front side of the first side cushion block 322 is flush with the front side of the middle cushion block 321, and the rear side of the second side cushion block 323 is flush with the rear side of the first cushion body 31. Figure 5As shown, the first pad body 31, the middle pad block 321, the first side pad block 322 and the second side pad block 323 are all square bodies, and the area of ​​the middle pad block 321 is relatively large, which can cooperate with the first pad body 31 to provide uniform support; the two first side pad blocks 322 located on both sides are used to support the thigh root, which can make the human body feel supported when the thigh is naturally placed, which is conducive to relaxation. In addition, by providing a gap between the first side pad block 322 and the second side pad block 323, the support for the greater trochanter joint of the thigh root can be weakened, so that the diaphragm feeling will not be caused by sitting for a long time, and the thigh muscle tension can be avoided.

[0050] Preferably, a distance L5 between the first side pad 322 and the second side pad 323 is 3-10 cm.

[0051] Furthermore, if Figure 5 As shown, the left and right sides of the first cushion body 31 are preferably flush with the left and right sides of the second cushion body 32, the left and right sides of the middle cushion block 321 are flush with the left and right sides of the square support surface, the thickness of the second side cushion block 323 is greater than the thickness of the first side cushion block 322, and the thickness of the first side cushion block 322 is equal to the thickness of the middle cushion block 321. By increasing the thickness of the second side cushion block 323, the support on both sides of the buttocks can be strengthened to prevent side tilting. For example, when the center of gravity of the human body is to the left, the second side cushion block 323 on the left side can use the thickness advantage to strengthen the support on the left side of the buttocks, thereby reducing the feeling of the human body tipping over to the left; when the center of gravity of the human body is to the right, the second side cushion block 323 on the right side can use the thickness advantage to strengthen the support on the right side of the buttocks, thereby reducing the feeling of the human body tipping over to the right.

[0052] Preferably, the difference in thickness between the second side pad 323 and the first side pad 322 is 2-10 cm. In addition, it should be noted that the thickness of the first pad 31 and the middle pad 321 may be equal or unequal, and may be adjusted according to the density / hardness of the materials selected, but the first pad 31 is preferably not harder than the middle pad 321. Specifically, according to one embodiment of the present invention, the first pad 31 and the second pad 32 are made of sponge of the same density, and the thickness of the first pad 31, the middle pad 321 and the first side pad 322 are equal.

[0053] In the present invention, the elastic pad 3 can be formed in one piece or assembled in pieces.

[0054] The present invention can ensure that the human body can get balanced support in various sitting postures through the structural improvement of the elastic pad 3 and its cooperation with the support seat 2, and can adjust the local force on the buttocks to promote the human body to relax, thereby effectively alleviating the discomfort caused by long-term bad sitting posture. Therefore, the seat cushion of the present invention has a high degree of comfort.

[0055] In the present invention, the mounting base 1 and the supporting base 2 may have any structure, and the present invention does not limit this. According to one embodiment of the present invention, Figure 4 As shown, the mounting seat 1 and the support seat 2 are both formed as square plate-shaped members. Of course, in order to achieve relative rotation between the mounting seat 1 and the support seat 2, according to an embodiment of the present invention, the seat cushion may further include a connecting device 4 for connecting the mounting seat 1 and the support seat 2 and enabling the support seat 2 to universally rotate relative to the mounting seat 1.

[0056] The connecting device 4 can be implemented in a variety of ways, as long as it can achieve universal rotation of the mounting base 1. For example, it can be a spring connected between the mounting base 1 and the support base 2, or it can be a spring such as the present invention. Fig.10 In the embodiment shown, the connecting device 4 includes a supporting member 41 supported between the mounting seat 1 and the supporting seat 2, and the upper portion of the supporting member 41 is a spherical body abutting against the lower surface of the supporting seat 2. Fig. 9 and Fig.10 As shown, the mounting seat 1 may be provided with a mounting hole for the lower end of the support member 41 to pass through, and the lower end of the support member 41 may be fixed to the mounting seat 1 by a nut 43 after passing through the mounting hole, and a gasket 42 may be sandwiched between the nut 43 and the mounting seat 1 to prevent wear. The connection between the support member 41 and the support seat 2 may be achieved by installing a connecting member 44 on the support member 41, and the connecting member 44 may be fixed to the support member 41 by a screw 45, and the connecting member 44 may be welded to the support seat 2.

[0057] In order to further improve the comfort of the seat cushion, a damping member (not shown) for buffering the rotation of the support seat 2 in the vertical direction may be provided between the mounting seat 1 and the support seat 2, so as to make the entire seat cushion softer. The damping member may be any known damping member, such as a spring, a sponge block, etc., and the present invention is not limited thereto.

[0058] In the present invention, the seat cushion can be used alone or in combination with a seat. In this case, the seat cushion can be directly placed on the seat for use, or the seat cushion and the seat can be integrated. Therefore, the present invention also provides a seat, which includes the seat cushion described above.

[0059] In the present invention, the seat cushion can also be used as a hip fitness device for fitness purposes. For example, the hip muscles can be directly used in conjunction with waist strength to operate the universal rotation of the elastic pad 3 and the support seat 2 relative to the mounting seat 1 to alleviate the discomfort of back pain.

[0060] The present invention also provides a system for fitness, which may include the above-mentioned seat cushion, position sensor and memory, wherein the position sensor is used to detect the position information of the support seat 2 relative to the mounting seat 1 and transmit the position information to the memory.

[0061] Among them, Fig. 9 As shown, a circuit board 5 may be arranged on the mounting base 1 of the seat cushion, and the position sensor and the memory may be integrated on the circuit board 5 .

[0062] The present invention also provides a system for fitness, which may include the above-mentioned cushion, position sensor and smart terminal, wherein the position sensor is used to detect the position information of the support seat 2 relative to the mounting seat 1 and transmit the position information to the smart terminal. In this way, the fitness situation can be monitored through the smart terminal (such as a mobile phone).

[0063] The smart terminal may include a game APP, and the game APP can receive the location information to associate with the game. This can increase the fun of fitness.
