[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Combination Figure 1-6 As shown, an embodiment of the utility model is described in detail. The embodiment of the utility model provides an airbag device, including a fixing frame 1, an airbag assembly 2, a hinge assembly 3, an upper waist plate 4, a lower waist plate 5, a limit block 6 and a sliding assembly 7; the two ends of the airbag assembly 2 are fixed to the two ends of the fixing frame 1, one end of the upper waist plate 4 is arranged at one end of the fixing frame 1 through the hinge assembly 3, the other end of the upper waist plate 4 is provided with a slider assembly 7, one end of the lower waist plate 5 is arranged at the other end of the fixing frame 1 through the hinge assembly 3, the lower waist plate 5 passes through the slider assembly 7 and is slidably arranged parallel to the upper waist plate 4, and the other end of the lower waist plate 5 is provided with the limit block 6; the upper waist plate 4 passes through the limit block 6 and is slidably arranged parallel to the lower waist plate 5;

[0018] The airbag assembly 2 is inflated to push up the upper waist plate 4 and the lower waist plate 5, so that the limit block 6 and the sliding assembly 7 move relative to each other. When the limit block 6 and the sliding assembly 7 touch each other, the airbag assembly 2 is inflated to the maximum state.

[0019] The airbag device includes an airbag assembly arranged under a double-layer top lumbar plate, and the airbag assembly is inflated and the top lumbar plate is opened to form an arch; after use, the airbag is deflated and the top lumbar plate can be restored to a flat state without affecting the appearance of the chair; when the airbag strength is opened to the maximum, the human body can be lifted; the height can be adjusted to support the waist, similar to the manual function; a double-layer top lumbar plate mechanism design is adopted, which can be stretched to form an arch, and the height of the arch fits the human waist; a pneumatic plus overlapping slider method is adopted to achieve the waist support and other functions, which is convenient / safe and can meet the physical needs of different users. It can be dislocated left and right to form a waist twisting function.

[0020] Further, in one example, Figure 2 As shown, the airbag device 2 further includes a lower elastic belt 8, which is arranged between the airbag assembly 2 and the lower top waist plate 5, and both ends are fixed to the fixing frame 1. In this way, the lower elastic belt 8 is arranged under the lower top waist plate 5, which can reduce the excessive friction between the two top waist plates and the airbag.

[0021] Further, in one example, Figure 1As shown, the airbag device further includes an upper elastic band 9, which is arranged above the upper lumbar plate 4, and the two ends of the upper elastic band 9 are fixed on the hinge assembly 3. The upper elastic band can assist in reducing the airbag pressure and prevent the upper lumbar plate and the lower lumbar plate from forming an excessive arch.

[0022] Further, in one example, Figure 4 As shown, the slider assembly 7 is a hollow strip, wherein the inner surface of the hollow portion is an arc or figure eight convex surface. In this way, when sliding in contact with the lower top waist plate 5, friction can be reduced.

[0023] Furthermore, in one embodiment, the stopper 6 is C-shaped or hollow and long. The contact surface between the stopper 6 and the upper waist plate 4 is an arc-shaped or figure-eight convex surface. Similarly, the friction force can be reduced when slidingly contacting the upper waist plate 4.

[0024] Furthermore, in one example, the airbag assembly 2 includes a first airbag 21 and a second airbag 22, one end of the first airbag 21 and one end of the second airbag 22 are respectively fixed to two ends of the fixing frame 1, and the first airbag 21 and the second airbag 22 are multi-layer airbags. Using multi-layer airbags can increase the height of the airbag inflation, and is also more conducive to adjusting the airbag to different inflation heights to meet users with different usage needs.

[0025] Furthermore, an embodiment of the present invention also provides a massage chair, which includes a chair frame 11, a base, a control device and an air pump, wherein the chair frame is arranged on the base, the chair frame 11 includes a seat 111 and a backrest 112, and the backrest 112 is provided with the above-mentioned first airbag device 1A and second airbag device 1B at positions corresponding to both sides of the user's waist, and the control device controls the air pump to inflate the first airbag device 1A and the second airbag device 1B respectively through the air valve to support the user's waist.

[0026] For example, when the massage chair is in a sitting position, the first airbag device and the second airbag device can be inflated at the same time with a small amount of air to support the user's waist and prevent the user's waist from being suspended in the air, thereby improving the comfort of the massage chair sitting position. When the massage chair is in a zero-gravity state at the back, the first airbag device and the second airbag device can be inflated to the maximum at the same time to stretch the user's waist and back, or the first airbag device and the second airbag device can be inflated separately on the left and right to achieve a waist twisting massage, enriching the massage techniques of the massage chair.

[0027] Furthermore, in one example, a massage movement is also included, and a guide rail is also provided on the chair frame. The control device controls the massage movement to reciprocate on the guide rail to massage the user.

[0028] There are various functions of massage chairs on the market. The waist is the key part of the human body. At present, there are relatively few waist protection and health care functions on massage chairs. Only ordinary air bags are set to achieve waist support. The function is single and the massage effect is poor. The massage chair provided by the utility model can not only provide waist support, but also cooperate with the massage movement to massage the user's waist and back, enriching the massage techniques.

[0029] Specifically, Figure 1-7 As shown, the first airbag device 1A and the second airbag device 1B are respectively arranged on the left and right sides of the waist of the massage chair, and the airbag device includes a fixing frame 1, an airbag assembly 2, a hinge assembly 3, an upper waist plate 4, a lower waist plate 5, a limit block 6 and a sliding assembly 7; the two ends of the airbag assembly 2 are fixed to the two ends of the fixing frame 1, one end of the upper waist plate 4 is arranged at one end of the fixing frame 1 through the hinge assembly 3, and the other end of the upper waist plate 4 is provided with a slider assembly 7, and one end of the lower waist plate 5 is arranged at the other end of the fixing frame 1 through the hinge assembly 3, and the lower waist plate 4 passes through the slider assembly 7 and slides parallel to the upper waist plate 4, and the other end of the lower waist plate 5 is provided with the limit block 6; the upper waist plate 4 passes through the limit block 6 and slides parallel to the lower waist plate 5. A lower elastic belt 8 is arranged below the lower waist plate 5, and the two ends are fixed to the fixing frame 1, which can reduce the excessive friction between the two top waist plates and the airbag. The upper elastic band 8 is arranged above the upper lumbar plate 4, and both ends are fixed on the hinge assembly 3. The upper elastic band 4 can assist in reducing the airbag pressure and prevent the arch formed by the upper lumbar plate and the lower lumbar plate from being excessive.

[0030] When the airbag device is inflated, the two top waist plates slide and stretch relative to each other, and bend upward into an arch shape. The top waist plate has a certain elasticity and hardness. After the support of the airbag, the top of the arch has a great support force. The designed top waist is arched, just fitting the user's waist, forming a waist support or top waist stretching effect. When deflated, the two top waist plates slide outward until they overlap and restore their original appearance. The height of the top waist can be adjusted by the inflation time, and when it is opened to the maximum intensity, it can perform the function of human body stretching. When the waist is empty, opening the low gear can assist in supporting the user's waist like a hand. When the waist is sore, the first airbag device and the second airbag device can be separated and dislocated left and right to form a waist twisting function effect, and finally the waist massage movement intensity function can be adjusted.

[0031] In addition, since the airbag device can be installed at any angle, it can be arranged to form an eight-shaped manner after inflation to support the user's waist, making the user feel better.

[0032] The airbag device adopts a superimposed top lumbar plate mechanism design, which is small in size and suitable for all massage chairs. It is easy to install and use, has a low cost, and is suitable for promotion.

[0033] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
