[0006] A split type backrest cushion, comprising a cushion body, a first backrest, a second backrest, an elastic connecting strip, a connecting shell connected with the cushion body, and a pneumatic massage module installed on the connecting shell, the elastic connecting strip is installed on the end face of the connecting shell away from the cushion body, and the first backrest and the second backrest are respectively installed on the two ends of the elastic connecting strip protruding out of the connecting shell.

[0007] The pneumatic massage module comprises a first inflation assembly, a second inflation assembly and a gas pump, the gas pump is installed in the connecting shell, and the first inflation assembly and the second inflation assembly are respectively installed on the end face of the connecting shell close to the cushion body.

[0008] The first inflation assembly comprises an air bag, an air pipe and an air nozzle installed on the side of the air bag close to the connecting shell, and the gas pump realizes communication with the air bag through the air pipe and the air nozzle.

[0009] The connecting shell is provided with limiting blocks on both sides, and the two ends of the elastic connecting strip protrude out of the connecting shell after passing through the limiting blocks on both sides of the connecting shell.

[0010] The elastic connecting strip is provided with a protruding part which is adapted to the shape of the connecting shell.

[0011] The split backrest cushion further comprises a key module arranged on one side of the cushion body, a control module arranged in the connecting shell, and a power supply module.

[0012] The split backrest cushion has the advantages that:

[0013] The split backrest cushion is separated from the first backrest and the second backrest, and the flexibility of the elastic connecting strip allows the angle and height of the backrest to be adjusted according to the needs of the user, thereby providing a more comfortable sitting experience.

[0024] In the prior art, some seat cushions have adjustable backrest functions, but they mostly rely on mechanical buckles or manual adjustment mechanisms, which are cumbersome to operate and lack dynamic adaptability. Seat cushions integrated with massage functions often embed massage modules inside the backrest, which increases the hardness of the backrest, affects comfort, and makes maintenance or replacement difficult. In addition, the existing split backrest design mostly uses rigid connection, lacks elastic buffering, is difficult to fit the human body curve, and cannot achieve dynamic support in different zones.

[0025] To solve the above problems, the present embodiment discloses a split backrest seat cushion, which has the structure as shown in Figures 1 to 4As shown, the split back seat cushion includes a seat cushion body 100, a first backrest 104, a second backrest 105, an elastic connecting strip 106, a connecting shell 107 connected with the seat cushion body 100, and a pneumatic massage module 108 installed on the connecting shell 107. The elastic connecting strip 106 is installed on the end of the connecting shell 107 away from the seat cushion body 100. The first backrest 104 and the second backrest 105 are respectively installed on the two ends of the elastic connecting strip 106 protruding out of the connecting shell 107.

[0026] In this embodiment, through the cooperation of the first backrest 104, the second backrest 105 and the elastic connecting strip 106, the left and right partitions of the backrest are independently adjusted. The elastic connecting strip 106 is preferably a metal structure. The elastic connecting strip 106 can adapt to the waist curve of the human body, provide dynamic support, relieve local pressure, allow the user to adjust the fit of the two backrests according to the needs, further absorb the vibration, and improve the riding comfort, especially suitable for long-time office or driving scenarios. The pneumatic massage module 108 is independently installed on the connecting shell 107 and separated from the backrest structure, which not only avoids the hardening problem of the backrest caused by the traditional embedded massage module, but also facilitates the maintenance or upgrade of the massage assembly.

[0027] Further, the pneumatic massage module 108 includes a first inflatable assembly 109, a second inflatable assembly 110 and a gas pump 111. The gas pump 111 is installed in the connecting shell 107. The first inflatable assembly 109 and the second inflatable assembly 110 are respectively installed on the end of the connecting shell 107 close to the seat cushion body 100.

[0028] Further, the split back seat cushion further includes a key module 101 installed on one side of the seat cushion body 100, a control module 102 installed in the connecting shell 107, and a power supply module 103. The gas pump 111, the key module 101, the pneumatic massage module 108 and the power supply module 103 are respectively electrically connected with the control module 102.

[0029] From Figure 1 It can be seen that the first inflatable assembly 109 and the second inflatable assembly 110 are respectively arranged on the connecting shell 107. The key module 101 is provided with a plurality of keys. By operating the key module 101 on one side of the seat cushion body 100 and with the aid of the pre-set parameters in the control module 102, the shape of the first inflatable assembly 109 and the second inflatable assembly 110 can be adjusted to realize different degrees and types of massage. In addition, a charging port is arranged on the key module 101 to realize the energy supplement of the power supply module 103. The power supply module 103 is preferably a lithium battery.

[0030] Specifically, from Figure 4It can be seen that the first inflatable assembly 109 includes an air bag 112, an air pipe and an air nozzle 113 arranged on the side of the air bag 112 close to the connecting shell 107, and the air pump 111 is in communication with the air bag 112 through the air pipe and the air nozzle 113. Figure 2 It can be seen that the connecting shell 107 and the elastic connecting strip 106 are respectively provided with through holes for the air nozzle 113 to protrude out, so as to realize compact overall structure; the inflation and contraction of the air bag 112 realizes the massage of the back of the human body by the air pump 111.

[0031] It should be noted that the structure of the second inflatable assembly 110 in the embodiment is the same as that of the first inflatable assembly 109, and will not be described here.

[0032] Further, the two sides of the connecting shell 107 are respectively provided with limiting blocks 114, and the two ends of the elastic connecting strip 106 respectively protrude out of the two ends of the connecting shell 107 after passing through the limiting blocks 114 on the two sides of the connecting shell 107; located between the two limiting blocks 114, the elastic connecting strip 106 is bent to be provided with a protruding part 115 adapted to the shape of the connecting shell 107. Through the arrangement of the limiting blocks 114 and the protruding part 115, the stable installation of the elastic connecting strip 106, the first backrest 104 and the second backrest 105 can be realized.

[0033] In summary, the split backrest cushion of the embodiment realizes the separation design of the cushion body 100, the first backrest 104 and the second backrest 105, and combines the flexibility of the elastic connecting strip 106, so that the angle and height of the backrest can be adjusted according to the needs of the user, thereby providing a more comfortable sitting experience; through the pneumatic massage module 108, the user can enjoy massage of different intensity and mode, help to relieve muscle fatigue, improve blood circulation and improve the overall comfort of the sitting posture. Therefore, the split backrest cushion of the present application has significant advantages in comfort, functionality and adaptability, can effectively solve the problems existing in the prior art, and meet the higher requirements of users for the seat.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited to the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
