Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a massage airbag and a seat system. Background Art

[0002] In the prior art, massage devices are widely used in various seat systems to provide users with a comfortable sitting and lying experience and health care functions. Among them, the massage airbag, as a key component, realizes the massage effect through inflation and deflation, and is popular because of its flexible structure and low cost. However, the traditional massage airbag design often has problems such as slow inflation and deflation rates, single structure, and limited massage effect, making it difficult to meet the user's needs for an efficient and diverse massage experience.

[0003] Specifically, traditional massage airbags are mostly single-layer or simple stacked designs, lacking a reasonable air flow path. During the inflation and deflation process, due to the lack of an effective ventilation structure between airbag units, the gas flow in the airbag is not smooth, resulting in a long inflation and deflation process, which affects the immediacy and efficiency of the massage. In addition, if the design of some airbags increases the number of layers to improve the massage effect, the lack of effective connection and ventilation design between layers makes it even more difficult for the gas to flow efficiently between layers. In addition, a single massage form is difficult to cover multiple acupoints and muscle groups of the user's body, limiting the comprehensiveness and depth of the massage. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide a massage airbag and a seat system, aiming to improve the inflation and deflation rate through a unique structural design, and at the same time achieve a more comprehensive and in-depth massage effect.

[0036] The following will, with reference to the accompanying drawings, elaborate on some embodiments of this utility model. Without conflict, the features in the following embodiments can be combined with each other.

[0037] Embodiment 1:

[0038] Please refer to Figures 1 - 3, the present utility model discloses a massage airbag, which is suitable for being configured on a seat and includes three airbag units 100 arranged in a stacked manner. Specifically, the massage airbag includes a first airbag unit 110, a second airbag unit 120, and a third airbag unit 130 that are sequentially arranged in a stacked manner from bottom to top. Each airbag unit 100 includes a piece 140 that is combined into one body. The piece 140 is divided into an upper piece 141 and a lower piece 142, and an inflation chamber 300 is formed between the upper piece 141 and the lower piece 142. The first airbag unit 110 is provided with an air port 111 for gas exchange, and the air port 111 is connected to a trachea 200 to realize the inflation and deflation functions of the massage airbag. Two through holes 400 that enable fluid communication between the first airbag unit 110 and the second airbag unit 120, and between the second airbag unit 120 and the third airbag unit 130 are arranged. Among them, in the inflated state, the massage airbag as a whole expands to form a fan shape, and the two through holes 400 are arranged along the radial direction of the fan shape to enable the gas to quickly fill the massage airbag during inflation. When in use, the first airbag unit 110 can be connected to a gas generating device through the trachea 200. The gas generating device can be an air pump. The first airbag unit 110 is connected to the second airbag unit 120 through two through holes 400 to inflate the second airbag unit 120 through the through holes 400, and then the gas flows into the third airbag unit 130 through the two through holes 400. By setting a plurality of through holes 400, the present utility model enables the first airbag unit 110, the second airbag unit 120, and the third airbag unit 130 to expand quickly, thereby realizing the height adjustment of the entire multi-layer massage airbag, so as to better support the human body. Moreover, by using gas as the injection source, the surface of the entire massage airbag can be soft and comfortable. When a person leans on it, the gas can also flow in the multi-layer airbags, so that the surface of the entire massage airbag undergoes an adaptive change and fits well with the human body, improving the comfort of the user when using it.

[0039] It should be noted that when referring to the inflated state in this embodiment, the massage airbag as a whole expands to form a fan shape, which is composed of the first airbag unit 110 and the second airbag unit 120 that form a fan shape in the inflated state and are located at the bottom and in the middle, and the third airbag unit 130 that forms a non-fan shape in the inflated state and is located at the top. In other embodiments, among the first airbag unit 110, the second airbag unit 120, and the third airbag unit 130, one of them can form a fan shape in the inflated state, and the other two can be non-fan shapes in the inflated state, or the first airbag unit 110, the second airbag unit 120, and the third airbag unit 130 can all be non-fan shapes in the inflated state, as long as the massage airbag formed by the three stacked together forms a fan shape in the inflated state. Details are not elaborated here.

[0040] Through the connection of the through holes 400 between the airbag units in this application, the massage airbags can be inflated and opened in sequence, enabling better control of the height of the airbags after inflation. At the same time, the stacked arrangement structure can achieve neat stacking after deflation. It should be noted that this multi-layer massage airbag can also have multiple airbag units, such as 4, 5, etc. The specific number can be adaptively adjusted according to the requirements of the seat system. The connection structure between any two adjacent airbag units can refer to the connection structure between the first airbag unit 110 and the second airbag unit 120, which will not be elaborated here. By setting multiple airbag units, the support thickness of the massage airbag can be increased, with a wider adjustment range, meeting the usage needs of different people. In addition, the multiple airbag units are stacked and connected to each other, enabling sequential inflation and opening, better controlling the height of the airbags after inflation. At the same time, the stacked arrangement structure can achieve neat stacking after deflation.

[0041] Please refer to Figures 4 - 5 , further, in order to fix each airbag unit 100 to each other, the airbag unit 100 has an annular welding part 150 arranged around the through hole 400, and the width of the annular welding part 150 is 4.0 mm. In addition, in order to prevent the upper cut piece 141 and the lower cut piece 142 of the airbag unit 100 from sticking at the composite position, a convex part is arranged around the through hole 400, and the thickness of the convex part is 0.65 mm. Further, the convex part includes a strip-shaped convex part 151 arranged around the outer edge of the through hole and circular convex parts 152 arranged circumferentially and staggered on the outer periphery of the strip-shaped convex part. By setting two different convex parts, gas can enter smoothly.

[0042] Please refer to Figures 6 - 7 , this massage airbag further includes at least one massage bump 500, which is disposed on the top of the third airbag unit 130 and filled with sponge inside. In the present utility model, the role of the massage bump 500 is to simulate human hands and elbows. Through the protruding shape, it simulates the position of human fingers, palms or elbows, and performs massage techniques such as pointing, pressing, kneading, pinching, pushing, and knocking on the body, thereby stimulating the human skin, muscles, meridians, acupoints and even bones, achieving the effect of traditional Chinese massage, promoting blood circulation in the human body, accelerating metabolism, relieving local muscle tension, and playing a role in relaxation and health care. The working principle of the present utility model is as follows: when massage is needed, the airbag unit is inflated, and the gas causes the bottom airbag unit 100 to expand and rise, providing a supporting force for the human body. The structure of the massage bump 500 at the top can greatly improve the massage effect; when massage is not needed, deflate the airbag, at this time the height of the bottom first airbag unit 110 is reduced, and the massage bump 500 retracts.

[0043] The present utility model further provides a seat system with a massage function; it includes the above-mentioned multi-layer massage air bags, which support the human body through the multi-layer massage air bags, making users feel more comfortable when sitting, especially being more friendly to those who sit for a long time, capable of massaging the human body and relieving the fatigue of the human body. Further, the multi-layer massage air bags are arranged at the position corresponding to the user's waist on the seat system, capable of supporting the waist of the human body. In other embodiments, the multi-layer massage air bags can also be used to support positions such as the legs, neck or head of the human body, so as to create a more comfortable seat system and improve the sitting comfort of personnel.

[0044] Embodiment 2:

[0045] The difference between this embodiment and Embodiment 1 is that in this embodiment, the massage air bag includes three air bag units 100 arranged in a stacked manner, which are connected through a connecting member, and a through hole for communicating the air bag units is defined in the connecting member, enabling them to be inflated and opened in sequence, and better controlling the height of the air bag after inflation; at the same time, the stacked structure can achieve neat stacking after deflation. It should be noted that the multi-layer massage air bag can also have a plurality of air bag units, such as 4, 5, etc. The specific number can be adaptively adjusted according to the requirements of the seat system, and the connecting member between any two adjacent air bag units can refer to the connecting member between the first air bag unit and the second air bag unit, which will not be elaborated here.
