DETAILED DESCRIPTION

[0021] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0022] See attached Figures 1 to 3A back cushion comprises: a cushion body 100 with a concave arc surface formed near the back side, a receiving groove 110 formed in the middle of the arc surface side of the cushion body 100, an airbag 210 installed in the receiving groove 110, and a cloth cover 300 sleeved on the cushion body 100 and the outside of the airbag 210. The receiving groove 110 can accommodate at least one airbag 210. Specifically, the length of the receiving groove 110 is equal to or approximately equal to the height of the airbag 210, and the width of the receiving groove 110 is smaller than the width of the receiving groove, so that the height of the airbag 210 can be appropriately adjusted in the receiving groove 110, and the airbag 210 is fixedly connected to the receiving groove 110 in a detachable manner.

[0023] In this embodiment, the pad body 100 is designed with a concave arc surface to adapt to the waist curve of the human body. At least one airbag 210 can be installed in the central accommodating groove 110. The waist curve and support requirements of different users can be adapted by adjusting the inflation amount of the airbag 210. By adjusting the position of the airbag 210 in the accommodating groove 110, the airbag 210 can be fine-tuned in the vertical direction, thereby realizing personalized adjustment of the height and size of the support part with the airbag 210 as the core.

[0024] In a further embodiment, an elastic connecting belt 310 is respectively provided on both sides of the cloth cover 300, and a Japanese-shaped buckle 311 is provided at the connecting ends of the two connecting belts 310. This ensures that the back cushion can be firmly and conveniently fixed on a chair or other seat to prevent the back cushion from sliding or shifting, thereby continuously providing effective lumbar support during long-term use.

[0025] In a further embodiment, the thickness of the upper part of the cushion body 100, the thickness of the lower part of the cushion body 100, and the thickness of the two sides of the cushion body 100 are all less than the thickness of the middle part of the cushion body 100. By thickening the middle part of the cushion body 100, sufficient space can be provided to set the airbag 210; with the use of the airbag 210, the back cushion can better match and support the natural curve of the human waist, and the waist can naturally sink into the thickened area in the middle to obtain concentrated support, avoiding full-range hard contact and increasing the comfort of use.

[0026] In a further embodiment, a detachable functional accessory 410 is provided inside the hollow area 320 of the cloth cover 300, and the functional accessory 410 includes one or a combination of infrared therapy equipment, heating equipment, and massage therapy equipment. The airbag 210 of the functional accessory 410 is just located inside the hollow area 320 of the cloth cover 300, ensuring that the functional accessory 410 can directly contact the user's skin or clothing, reducing the obstruction of the cloth and improving the transmission efficiency of the treatment or relaxation effect.

[0027] In a further embodiment, the outer surface of the airbag 210 is covered with a reinforcement layer, and the reinforcement layer is made of nylon, Kevlar fiber or other composite materials to ensure that the airbag 210 will not be accidentally ruptured during repeated installation and disassembly. Specifically, at least one Velcro fur surface 510 is arranged in the circumference and horizontal direction of the reinforcement layer; at least two Velcro thorn surfaces 520 are arranged in the vertical direction inside the accommodating groove 110; and at least two Velcro thorn surfaces 520 are arranged in the vertical direction of the functional accessory 410. The Velcro system is used to achieve the fixation and adjustment between the airbag 210, the accommodating groove 110 and the functional accessory 410.

[0028] In a further embodiment, a ventilation line 220 is connected to the airbag 210, and the ventilation line 220 passes through the cushion body 100 and the cloth cover 300 to the outside of the cloth cover 300, and is connected to the inflation device 230. The inflation device 230 is an inflatable balloon. The user only needs to manually squeeze the balloon to inflate the airbag 210 of the cushion, and vice versa, and deflate the air through the valve on the inflatable balloon to adjust the comfort and support effect of the cushion to achieve a highly personalized adaptation. Similarly, the functional accessory 410 passes through the cushion body 100 and the cloth cover 300 to the outside of the cloth cover 300 through a line, and is connected to a power source and a controller 420. Specifically, by setting the wiring channel 111 on the pad body 100 and the cloth cover 300, the inflation device 230, the power supply and the controller 420 are led out, which not only facilitates the user's operation and control, but also migrates the power supply and the controller 420 to the outside, which can make the overall feeling of the lumbar pillow softer and more uniform, and will not feel foreign body sensation or discomfort when using it, ensuring the experience.

[0029] In a further embodiment, the cushion body 100 is made of memory foam material. The cushion can gradually deform according to the body pressure, closely fit the user's body curve, especially the waist area, provide personalized support, and prevent back pain and lumbar muscle strain. When the pressure is released, it can slowly return to its original shape, which ensures the comfort and support effect of long-term use.

[0030] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
