Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of air bags, and in particular to an air bag, a pneumatic massage system and a massage seat. Background Art

[0002] Pneumatic massage seats have a pneumatic massage system added to the seat, in which air is provided by an air pump, and a number of air bags are distributed in the seat back. The inflation and deflation of each air bag are controlled, and thus the expansion and contraction of each air bag are controlled, thereby realizing the function of massaging the human body during the expansion and contraction process of the air bag.

[0003] The bag body of the air bag is usually made of two upper and lower sheets welded together. In the center of the bag body, there is an air-filled space surrounded by the upper and lower sheets and their welded edges. The inflation and deflation process of the air bag is the process of inflating the air into the air-filled space to expand the air bag and deflation of the air from the air-filled space to shrink the air bag. However, please refer to Figure 1 As shown, the edges of the inflation space 101 of the existing airbags are all smooth arc edges or straight edges. For example, when the airbag is a circular airbag, the edge of the inflation space is a smooth arc edge, or when the airbag is a quadrilateral airbag, the edge of the inflation space is a straight edge. When the airbag is inflated, the central area of ​​the airbag is compressed, and the gas first fills the middle of the inflation space and then expands to the periphery of the inflation space. Due to the inconsistency of the whole circle characteristics, fusion differences and sheet pre-deformation, the airbag will be subjected to uneven force and large deformation in this process. The airbag is pulled during the inflation process and serious wrinkles are generated, so that a huge concave area is formed on the surface of the airbag, such as Figure 2 As shown, the position and number of the huge depressed areas are uncontrollable. If the inflation continues, the huge depressed areas will undergo a sudden change in elasticity and bounce open, causing abnormal noise, which seriously affects the user experience. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide an air bag, in which a recessed area is arranged in the inflation space of the air bag, and the recessed area forms a recessed portion after inflation, so that the deformation of the air bag is small, the wrinkles are not obvious, and the small wrinkled area will not have a sudden elastic change and bounce open during the inflation process, thereby avoiding abnormal noise and improving the user experience.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an air bag, including a bag body, wherein the bag body has an inflation space, and the periphery of the inflation space has a plurality of recessed areas concave toward the center of the inflation space, and after the bag body is inflated and expanded, the recessed areas of the inflation space form a recessed portion.

[0006] Optionally, there are multiple recessed areas, and the multiple recessed areas are evenly distributed around the periphery of the inflation space.

[0007] Optionally, when viewed along the thickness direction of the airbag, the recessed area has an arc-shaped edge.

[0008] Optionally, when viewed along the thickness direction of the airbag, the recessed area has straight edges.

[0009] In order to solve the above technical problems, another technical solution adopted by the utility model is: to provide an air bag, including a plurality of bag bodies, which are stacked in sequence from top to bottom, and the bag bodies have an inflatable space; the periphery of the inflatable space of at least one of the bag bodies has a plurality of recessed areas concave inward toward the center of the inflatable space, and after the bag body is inflated and expanded, the recessed areas of the inflatable space form a recessed portion.

[0010] Optionally, a plurality of the bag bodies are connected in sequence, and at least one of the bag bodies is provided with an inflation nozzle.

[0011] Further optionally, the inflation nozzle is arranged on the bag body at the bottom layer.

[0012] Optionally, the airbag of any of the above items further comprises a massage head, and the massage head is arranged on the outer top surface of the airbag.

[0013] In order to solve the above technical problems, another technical solution adopted by the present invention is: to provide a pneumatic massage system, which includes any of the above-mentioned air bags.

[0014] In order to solve the above technical problems, another technical solution adopted by the present invention is: to provide a massage chair, which is provided with any of the above-mentioned air bags or the above-mentioned pneumatic massage system.

[0015] The air bag of the utility model has a plurality of concave areas concave toward the center of the inflatable space at the periphery of the inflatable space of the bag body. After the bag body is inflated and expanded, the concave areas of the inflatable space form concave parts. Therefore, when the air bag is inflated, the concave areas of the inflatable space form concave parts in advance, so that the corresponding parts of the surface of the bag body corresponding to the concave parts form a plurality of small wrinkle areas. The small wrinkles are not obvious and will not form huge concave wrinkles. The plurality of small wrinkle areas make the deformation of the bag body during the inflation process smaller, and the plurality of small wrinkle areas will not have sudden elastic changes and bounce open during the continued inflation process, thereby avoiding abnormal noise and improving the user experience.

[0016] Furthermore, the air bag of the utility model can be provided with a plurality of bag bodies stacked in sequence from top to bottom, and the inflation space of at least one of the bag bodies has a recessed area. The stacking of the plurality of bag bodies can achieve different inflation heights of the air bag to achieve different massage effects.

[0017] Furthermore, the air bag of the utility model can be provided with a massage head. By adding the massage head to simulate the massage of human fingers, the massage pressure can be increased to achieve a better massage effect.

[0018] The pneumatic massage system of the utility model adopts the air bag as a massage inflation bag, which can effectively avoid abnormal noise during the massage inflation process, and is conducive to improving the user experience.

[0019] The massage seat of the utility model is provided with a pneumatic massage system, which can massage the passengers, thereby relieving the fatigue of the passengers and improving the riding comfort. Moreover, the pneumatic massage system uses the air bag as the massage inflation bag, and there is no abnormal sound during the massage inflation, thus ensuring the user experience.

[0031] In order to facilitate the understanding of the utility model, the utility model is described in more detail below in conjunction with the accompanying drawings and specific embodiments. When an element is described as "connected" to another element, it can be directly connected to another element, or there can be one or more centered elements therebetween.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0033] The air bag 100 of the present utility model embodiment is shown in FIG. Figures 3 to 7 As shown, the bag body 1 includes a bag body 1. The bag body 1 has an inflatable space 101, and a gas nozzle 2 connected to the inflatable space 101 is arranged on the bag body 1. When working, the bag body 1 is expanded by filling the inflatable space 101 with gas through the gas nozzle 2, or the gas in the inflatable space 101 is deflated through the gas nozzle 2 to shrink the bag body 1. The expansion and contraction state switching process of the bag body 1 can correspond to the squeezing and relaxing process of massage, thereby realizing the massage function in the massage system.

[0034] The bag body 1 includes a first sheet 11 and a second sheet 12. Specifically, the first sheet 11 and the second sheet 12 are arranged opposite to each other, such as upper and lower opposite to each other; the first sheet 11 and the second sheet 12 are both made of a weldable material, and during molding, the opposite sides of the first sheet 11 and the second sheet 12 are bonded by high-frequency welding or the like to form a sealed joint, so that the area between the first sheet 11 and the second sheet 12 is enclosed to form an inflatable space 101. In an optional embodiment, the first sheet 11 and the second sheet 12 can be any form of weldable sheet, including but not limited to a multi-layer composite sheet or a single-layer sheet, and the material thereof is specifically a weldable plastic material, such as, but not limited to, polycarbonate (PC), thermoplastic polyurethane elastomer (TPU), polyvinyl chloride (PVC) material, etc.

[0035] The air nozzle 2 disposed on the bag body 1 can be disposed on the first sheet 11 or the second sheet 12 and communicated with the inflation space 101, or disposed between the first sheet 11 and the second sheet 12 and communicated with the inflation space 101. In a preferred embodiment, the air nozzle 2 is disposed between the first sheet 11 and the second sheet 12, and is fixed and communicated with the formed inflation space 101 when the first sheet 11 and the second sheet 12 are welded at opposite edges.

[0036] The inflatable space 101 formed by the first sheet 11, the second sheet 12 and the welded joint of the opposite sides thereof is a deformable space, that is, in the uninflated state, the first sheet 11 and the second sheet 12 tend to be close to each other in the thickness direction so that the whole bag body 1 is in a contracted state; while in the inflated state, the first sheet 11 and the second sheet 12 tend to separate from each other in the thickness direction so that the whole bag body 1 is in a bulging and expanding state. In the inflation process, the welded joint between the first sheet 11 and the second sheet 12 is tightened inwardly toward the center direction under the pulling action of the first sheet 11 and the second sheet 12 separating from each other.

[0037] Specifically, a plurality of recessed areas 13 are provided on the periphery of the inflatable space 101, and the plurality of recessed areas 13 are formed by being concavely arranged from the edge of the inflatable space 101 toward the center of the inflatable space 101. It can be understood that the recessed area 13 can be consistent with the structural portion that protrudes toward the center of the inflatable space 101 from the inner edge of the welded edge joint of the first sheet 11 and the second sheet 12.

[0038] Based on the setting of the recessed area 13, during the inflation process of the airbag 100, the welded joint between the first sheet 11 and the second sheet 12 is tightened toward the center and folded along the recessed area 13. When the airbag 100 is inflated, the recessed area 13 of the inflation space 101 shrinks inward and a recessed portion is pre-formed at the periphery of the inflation space 101, so that after the inflation space 101 is inflated and expanded, a plurality of folds 14 are formed along the recessed portions at corresponding positions of the surface of the bag body 1 corresponding to the plurality of recessed portions formed by the plurality of recessed areas 13. The plurality of folds 14 are directional fold areas preformed along the recessed area 13 during the inflation process. The axial direction of the fold area is parallel or nearly parallel to the thickness direction X. The forming process and the forming position are directional along the recessed area 13 rather than random. The formed folds 14 are small folds which are not obvious on the surface of the bag body 1 and do not form huge recessed folds. The plurality of small fold areas make the deformation of the bag body 1 smaller during the inflation process. In the process of continuing to inflate the inflation space 101, the plurality of folds 14 will not undergo elastic mutation and bounce open, thereby avoiding the generation of abnormal noise during the inflation process.

[0039] When the airbag 100 is deflated, the inflation space 101 is deflated through the air nozzle 2 and shrinks to the initial uninflated state, the concave portion therein disappears and the shape of the concave area 13 is restored, and the wrinkles 14 on the surface of the bag body 1 disappear and the surface of the bag body 1 is restored to a smooth shape.

[0040] The plurality of recessed areas 13 may be multiple, such as more than two, and the surface of the bag body 1 after inflation forms multiple wrinkles 14 corresponding to the multiple recessed areas 13; the multiple recessed areas 13 may be an odd number or an even number. Moreover, the multiple recessed areas 13 may be evenly distributed or unevenly distributed around the inflation space 101. Figures 3 to 7 In the specific embodiment shown, an even number of recessed areas 13 are evenly distributed around the periphery of the inflatable space 101 . For example, in the specific embodiment shown, there are 8 recessed areas 13 , and the 8 recessed areas 13 are evenly distributed around the periphery of the inflatable space 101 .

[0041] Based on the arrangement of multiple recessed areas 13, when observed along the thickness direction X of the airbag 100, the periphery of the inflatable space 101 is polygonal, which can be a regular polygon or an irregular polygon, or a quasi-polygon, or a combination of the above, and can be determined specifically according to the shape of the edge on the recessed area 13. For example, in some preferred embodiments, when observed along the thickness direction X of the airbag 100, the recessed area 13 has a straight edge, which can be a straight edge circumscribed to the inflatable space 101, wherein the periphery of the inflatable space 101 is a regular polygon, such as an octagon. Alternatively, in some other preferred embodiments, when observed along the thickness direction X of the airbag 100, the recessed area 13 has an arcuate edge, which is an arcuate edge concave toward the center of the inflatable space 101, wherein the periphery of the inflatable space 101 is a quasi-polygon, specifically a petal shape, and the overall bag body 1 has a beautiful appearance. It can be understood that when observed along the thickness direction X of the airbag 100, it mainly refers to observing the inflatable space 101 in an uninflated state.

[0042] In some embodiments, the outer periphery of the bag body 1, i.e., the outer periphery after the first sheet 11 and the second sheet 12 are joined at opposite sides, can be any shape, such as a circle or a polygon. Optionally, the outer periphery of the bag body 1 and the outer periphery of the inflation space 101 can be of different shapes and structures.

[0043] In another preferred embodiment, the air bag 100 may have a plurality of bag bodies 1, wherein the plurality of bag bodies 1 are stacked in sequence along the thickness direction X, such as stacked in sequence from top to bottom. Figure 8In the specific embodiment shown, the airbag 100 has three bag bodies 1, specifically a first bag body 1a, a second bag body 1b and a third bag body 1c, which are stacked in sequence from top to bottom. Specifically, at least one bag body 1 among the multiple bag bodies 1 is the above-mentioned bag body, that is, the inflation space 101 of at least one bag body 1 is an inflation space 101 with a recessed area 13; obviously, in an optional embodiment, the multiple bag bodies 1 can all be bag bodies whose inflation space 101 is an inflation space 101 with a recessed area 13. As shown in the specific embodiment, the first bag body 1a, the second bag body 1b and the third bag body 1c are all bag bodies whose inflation space 101 is an inflation space 101 with a recessed area 13, and the first bag body 1a, the second bag body 1b and the third bag body 1c can form small wrinkles on the surface after being inflated; or, in an optional embodiment, any one or two of the first bag body 1a, the second bag body 1b and the third bag body 1c can be an inflation space 101 with a recessed area 13, and the inflation space 101 of the remaining two or one bag body 1 is not provided with a recessed area 13.

[0044] Based on the different inflation amounts of the bag bodies 1 in the air bag 100, the entire air bag 100 can be inflated to different heights, thereby achieving different massage effects as needed.

[0045] Among the multiple bag bodies 1, any two of them can be isolated or connected; and in the air bag 100 composed of more than three bag bodies 1, the relationship between any two of the multiple bag bodies 1 can also be a combination of isolation and connection, such as the first bag body 1a and the second bag body 1b are isolated from each other, while the second bag body 1b and the third bag body 1c can be connected to each other.

[0046] The number of the air nozzles 2 of the airbag 100 can be at least one according to the interconnectedness of the multiple bag bodies 1. In particular, when the multiple bag bodies 1 are isolated from each other, the multiple bag bodies 1 can be independently provided with corresponding air nozzles 2 to inflate or deflate the corresponding bag bodies 1. Among the multiple bag bodies 1, between two interconnected bag bodies 1, the air nozzle 2 can be provided on only one of the bag bodies 1. Of course, one air nozzle 2 can be provided on each of the two connected bag bodies 1 to speed up the inflation and deflation.

[0047] In some other preferred embodiments, the multiple bag bodies 1 may be connected to each other, that is, the multiple bag bodies 1 are connected to form an integral air bag 100, wherein the air nozzle 2 may be provided on at least one bag body 1. Figure 8In the specific embodiment shown, the first bag body 1a, the second bag body 1b and the third bag body 1c are connected in sequence from top to bottom, and the air nozzle 2 is arranged on the third bag body 1c at the bottom layer and is directly connected to the inflation space 101 of the third bag body 1c. The single air nozzle 2 realizes inflation and deflation of the overall connected air bag 100. During inflation, the gas first enters the inflation space 101 of the third air bag 1c through the air nozzle 2, and then enters the inflation space 101 of the second bag body 1b and the first bag body 1a in sequence. During deflation, the gas in the inflation space 101 of the third bag body 1c, the second bag body 1b and the first bag body 1a is discharged from the air nozzle 2 in sequence.

[0048] In another preferred embodiment, a massage head is also provided on the air bag 100. When viewed along the thickness direction X of the air bag 100, the area of ​​the massage head is smaller than the area of ​​the bag body 1. When viewed along the direction intersecting the thickness direction X of the air bag 100, the massage head is in the shape of a convex block or a semi-spherical shape, and generates a greater pressure when subjected to force. The material of the massage head can be the same as or different from that of the bag body 1, such as but not limited to PVC or TPU material.

[0049] Specifically, the massage head is disposed on the outer top surface of the air bag 100. Figures 3 to 7 In the single-layer air bag 100 of the single bag body 1 shown, the massage head is directly arranged on the outer top surface of the single-layer air bag 100; Figure 8 In the illustrated multi-layer airbag 100 of multiple bag bodies 1, the massage head is arranged on the outer top surface of the first bag body 1a. The massage head is arranged on the outer top surface of the airbag 100 as a fixed arrangement, which is fixed on the outer top surface of the airbag 100, and can be specifically an integrated fixed arrangement or an adhesive arrangement.

[0050] When in use, the outer top surface of the air bag 100 is the surface of the bag body 1 adjacent to the massaged body. The massage head is supported by the bag body 1 of the air bag 100 and is used to simulate human finger massage, which can increase massage pressure and achieve better massage effect.

[0051] The pneumatic massage system of the embodiment of the utility model comprises the above-mentioned air bag 100. It is understandable that in the pneumatic massage system, it is obvious that an air pump for providing air to the air bag 100 may also be included, the air pump is connected to the air nozzle 2 on the air bag 100, and / or, a control valve for controlling the air filling speed and air filling amount of the air bag 100 may be included. The structure and function of the air bag 100 can be referred to the above-mentioned embodiment, and will not be described one by one here.

[0052] The pneumatic massage system of the utility model adopts the air bag 100 as a massage inflation bag, which can effectively avoid abnormal noise during the massage inflation process, thereby improving the user experience.

[0053] The massage seat of the embodiment of the utility model is provided with the above-mentioned air bag 100 or the above-mentioned pneumatic massage system. The massage seat at least includes a seat bracket capable of providing support for the above-mentioned air bag 100 or the above-mentioned pneumatic massage system, such as a seat backrest, so that the air bag 100 can be installed on the seat in a fixed position to achieve the function of fixed-point massage during massage operation. The structure and function of the air bag 100 and the pneumatic massage system can be referred to the above-mentioned embodiment, and will not be described one by one here.

[0054] The massage seat of the utility model is provided with a pneumatic massage system, which can provide a massage function for passengers, which is helpful to relieve the fatigue of passengers and improve the riding comfort. Moreover, the pneumatic massage system uses the above-mentioned air bag 100 as a massage inflation bag, and there is no abnormal sound during massage inflation, which improves the user experience.
