[0047] Combination Figures 1 to 3 An embodiment of this utility model provides a backrest cushion, which includes a support assembly 100, an elastic element 200, a lumbar support element 300, and an airbag 400.

[0048] Multiple elastic elements 200 are fixed to the bracket assembly 100.

[0049] The lumbar support 300 has a shape that matches the human waist, better conforming to ergonomic design principles and improving comfort. The lumbar support 300 is connected to the elastic element 200, and is fixed to the support assembly 100 via the elastic element 200; that is, the first end of each elastic element 200 can be fixed to the support assembly 100, and the reverse side of the lumbar support 300 is fixed to the second end of each elastic element 200. The elasticity of the elastic element 200 ensures that the lumbar support 300 always conforms to the user's waist, and the elastic element 200 automatically adjusts its fit to the user's waist according to their forward or backward leaning movements.

[0050] The airbag 400 is located on the front of the lumbar support 300 to reduce pressure on the lower back and improve comfort and user experience.

[0051] It is understood that the cushion provided in the embodiment of this utility model provides a backrest by setting multiple elastic elements 200 between the lumbar support member 300 and the bracket assembly 100. The elasticity of the elastic elements 200 is used to make the lumbar support member 300 always fit the user's waist, thereby reducing the gap between the cushion and the user's waist, improving the support effect on the waist, and enhancing comfort and user experience.

[0052] Furthermore, an airbag 400 is installed on the lumbar support component 300 to reduce the pressure on the lower back and further improve comfort and user experience.

[0053] Combination Figure 1 and Figure 2 In some embodiments of this invention, the cushion also includes an air pump 500. The air pump 500 is connected to the air bag 400 and can provide gas to the air bag 400, allowing the air bag 400 to inflate more easily, thereby better reducing the pressure on the user's waist after contact with the cushion.

[0054] Combination Figure 1 In some embodiments of this utility model, the lumbar support member 300 includes a first support member 310 and a second support member 320 that are connected to each other.

[0055] The first support member 310 and the second support member 320 are both arc-shaped, which better conforms to the shape of the waist and can better support the waist, thus providing better comfort.

[0056] The first side of the first support member 310 is fixedly connected to the first side of the second support member 320, the second side of the first support member 310 extends to the outside of the airbag 400, and the second side of the second support member 320 extends to the outside of the airbag 400.

[0057] The second side of the first support member 310 and the second side of the second support member 320 are elastic, making the cushion suitable for users with large waists, thus broadening its applicability.

[0058] In addition, combined Figure 3 In some embodiments of this utility model, the elastic element 200 includes a first elastic element 210 and a second elastic element 220.

[0059] The first elastic element 210 is fixedly connected to the first support element 310, and the second elastic element 220 is fixedly connected to the second support element 320, so that both the first support element 310 and the second support element 320 can fit tightly against the user's waist under the action of elasticity.

[0060] Moreover, the airbag 400 includes a first airbag 410 and a second airbag 420. The first airbag 410 is fixed to the first support member 310, and the second airbag 420 is fixed to the second support member 320. This allows the user's waist to fit more fully with the airbag 400, with more contact points between the waist and the airbag 400, resulting in less pressure on the waist and greater comfort.

[0061] Combination Figure 1 and Figure 2 In some embodiments of this utility model, the bracket assembly 100 includes a bracket base 110 and a support frame 120.

[0062] The bracket base 110 is slidably connected to the support frame 120, and the elastic element 200 is fixed on the bracket base 110; this allows the elastic element 200 and the lumbar support 300 fixedly connected to the elastic element 200 to slide along the bracket base 110, which can meet the needs of users of different heights and has a wider range of applications.

[0063] Specifically, in combination Figure 1 and Figure 3 In some embodiments of this utility model, a plurality of fixing holes 111 are provided on the support base 110 along the height direction, and a plurality of fixing bosses 121 are provided on the support frame 120.

[0064] Each fixing boss 121 engages with each fixing hole 111, making it easier to adjust the height of the bracket base 110 by simply engaging the fixing boss 121 on the support frame 120 with the corresponding fixing hole 111.

[0065] Of course, combined Figure 2 In order to enable the bracket base 110 to slide more stably on the support frame 120, in some embodiments of the present invention, a first groove 112 is provided on the first side of the bracket base 110, and a second groove 113 is provided on the second side of the bracket base 110.

[0066] A first slide rail 122 is provided on the first side of the support frame 120, and a second slide rail 123 is provided on the second side of the support frame 120.

[0067] The first slide rail 122 is slidably connected to the first slide groove 112, and the second slide rail 123 is slidably connected to the second slide groove 113.

[0068] Combination Figure 3 In some embodiments of this utility model, the first elastic member 210 and the second elastic member 220 are symmetrically arranged.

[0069] The first elastic element 210 is disposed on the first side of the bracket base 110, and the second elastic element 220 is disposed on the second side of the bracket base 110.

[0070] This makes the force on the first elastic member 210 and the second elastic member 220 more even, and can better support the first support member 310 and the second support member 320.

[0071] Combination Figure 2 In some embodiments of this utility model, the cushion also includes a battery 510, a PCB module 520, and an air valve 530.

[0072] The support base 110 is provided with a receiving cavity 114, in which the battery 510, PCB module 520 and air valve 530 are all located, which facilitates storage and saves space, simplifying the overall structure of the cushion.

[0073] Both the battery 510 and the PCB module 520 are electrically connected to the air pump 500. The battery 510 supplies power to the air pump 500, and the PCB module 520 can control the air pump 500.

[0074] The air pump 500 is connected to the airbag 400 via the air valve 530. The air valve 530 includes a first air valve 531 and a second air valve 532. The air pump 500 is connected to the first air valve 531 and the second air valve 532. The first air valve 531 is connected to the first airbag 410, and the second air valve 532 is connected to the second airbag 420. Each airbag is equipped with an independent air valve, which facilitates the control of the inflation and deflation of each airbag for massage.

[0075] Furthermore, other massage components or heating devices can be installed on the lumbar support 300, providing greater flexibility.

[0076] Of course, the receiving cavity 114 can also be set on the opposite side of the lumbar support 300, which can also save space and make the structure simpler.

[0077] In addition, combined Figure 1 and Figure 2 In some embodiments of this utility model, the support frame 120 is provided with a clearance space 124.

[0078] The clearance space 124 is larger than the receiving cavity 114; after the support base 110 and the support frame 120 slide close to each other, the receiving cavity 114 of the support base 110 can be hidden in the clearance space 124, which makes the structure simpler and saves space.
