Description

Technical Field

[0001] This application relates to the field of pneumatic massage airbag technology, and more particularly to a car seat massage airbag. Background Technology

[0002] Cars have become an indispensable means of transportation in people's lives. As people's living standards continue to improve, their functional requirements for car seats are also increasing. Massage devices have naturally become an essential part of car seats.

[0003] The massage structure in existing car seats typically consists of multiple layers of massage airbags that inflate and deflate to provide a massage function. Regardless of the number of layers, to achieve sufficient massage intensity, the airbags must have sufficient support height after inflation and deformation; in other words, the airbags need to have a sufficient volume.

[0004] However, the current massage airbags are all close in size. In order to make the massage airbags have a better massage intensity, it is necessary to increase the lifting of the massage airbags. This results in the massage airbags taking too long to inflate and deflate, and the volume of the airbags changes slowly. This reduces the massage intensity felt by passengers and affects the massage effect. Utility Model Content

[0005] This application provides a car seat massage airbag to solve the problem of insufficient massage intensity caused by long inflation and deflation times of massage airbags.

[0006] This application provides a car seat massage airbag, including a support airbag, a massage airbag, an air tube, a first air valve, and a second air valve. The support airbag is used to be installed on the foam backrest of the seat and has an air inlet. The massage airbag abuts against the support airbag and is located on the side of the support airbag away from the backrest, and also has an air inlet. The air tube independently connects to the air inlets of the support airbag and the massage airbag, and is used to independently inflate and deflate the support airbag and the massage airbag. The first air valve is located on the air tube connecting to the support airbag and controls the connection and closure between the air tube and the support airbag. The second air valve is located on the air tube connecting to the massage airbag and controls the connection and closure between the air tube and the support airbag.

[0007] The massage airbags on the foam backrest of the seat in this application are divided into two parts: a support airbag and a massage airbag. The two are connected by independent air tubes for inflation and deflation. Different first and second air valves control the inflation and deflation states of the massage airbag and the support airbag respectively. The support airbag can increase the height of the massage airbag, thereby enhancing the massage effect. In addition, the support airbag can reduce the volume of the massage airbag, avoiding the slow inflation and deflation speed caused by a large massage airbag, thus ensuring the massage effect.

[0008] Meanwhile, the support airbag and massage airbag in this solution can achieve different massage effects by adjusting the inflation state of the support airbag.

[0009] When a gentler massage is needed, the support airbag can be left uninflated or not inflated at all, resulting in a shorter travel distance for the massage airbag after inflation, thus reducing the massage intensity. Alternatively, the support airbag can be fully inflated, and the first air valve can be closed during the massage, allowing the massage airbag to expand to a position further away from the seat back, increasing the massage intensity. When a stronger massage is needed, the support airbag and massage airbag can be inflated and deflated simultaneously, allowing the massage airbag to travel a greater distance in a short time, resulting in a stronger massage.

[0010] In some embodiments of this application, multiple support airbags are provided, spaced apart on the seat back; multiple massage airbags are also provided, each corresponding to one of the support airbags, with the massage airbags abutting against their respective support airbags. The multiple support airbags and massage airbags can increase the contact area between the massage airbags and the passenger's back, resulting in a better massage effect.

[0011] In some embodiments of this application, multiple support air bags are connected, and all the support air bags form an air inlet, with an air tube connected to the air inlet of the support air bags. Multiple support air bags sharing a single air inlet facilitates the connection and inflation / deflation of the multiple support air bags and air tubes.

[0012] In some embodiments of this application, multiple massage airbags operate independently, with air tubes independently connected to the air inlets of each airbag. Multiple second air valves are provided, each corresponding to one of the massage airbags, and are located on the air tube connected to the corresponding airbag. Independent air supply to different massage airbags allows for different inflation / deflation states in the airbags on different parts of the back, resulting in better localized massage effects.

[0013] In some embodiments of this application, the massage airbags are configured with at least three layers, extending along the extension direction of the support airbags and the massage airbags. Having at least three layers allows the massage airbags themselves to have a greater length perpendicular to the seat back, thereby increasing the massage intensity.

[0014] In some embodiments of this application, any two adjacent massage air bags in at least three layers are connected. This connection of at least three layers of massage air bags allows each air bag to have only one air inlet, facilitating the arrangement of the air tubes and reducing installation difficulty.

[0015] In some embodiments of this application, the air inlet of the massage air bag is located on a layer of massage air bags near the supporting air bag. The air tube is usually installed on the back of the seat, and the air inlet is located on the massage air bag near the back of the seat, which facilitates the connection and fixation of the air tube to the massage air bag.

[0016] In some embodiments of this application, the support airbags are configured as at least two layers, extending along the distribution direction of the support airbags and the massage airbags. At least two layers of support airbags allow the support airbags to provide greater support height for the massage airbags, thereby increasing the massage intensity of the massage airbags.

[0017] In some embodiments of this application, the massage airbags are projected onto the support airbags along the distribution direction of the support airbags and massage airbags. The area of ​​the massage airbags is smaller than that of the support airbags, which allows the massage airbags to be stably supported on the support airbags. Attached Figure Description

[0030] Cars have become an indispensable means of transportation in people's lives. As people's living standards continue to improve, their functional requirements for car seats are also increasing. Massage devices have naturally become an essential part of car seats.

[0031] The massage structure in existing car seats typically consists of multiple layers of massage airbags that inflate and deflate to provide a massage function. Regardless of the number of layers, to achieve sufficient massage intensity, the airbags must have sufficient support height after inflation and deformation; in other words, the airbags need to have a sufficient volume.

[0032] However, the current massage airbags are all close in size. In order to make the massage airbags have a better massage intensity, it is necessary to increase the lifting of the massage airbags. This results in the massage airbags taking too long to inflate and deflate, and the volume of the airbags changes slowly. This reduces the massage intensity felt by passengers and affects the massage effect.

[0033] Therefore, please refer to Figure 1 This application provides a car seat massage airbag 3, including a support airbag 1, a massage airbag 3, an air tube 4, a first air valve, and a second air valve.

[0034] Please refer to Figure 1 The support airbag 1 is used to install on the foam backrest of the seat, and the support airbag 1 has an air inlet 11. The support airbag 1 can be fixed to the backrest 2 of the seat by zipper, sewing, Velcro, or buckle; the material of the support airbag 1 can be one or more of thermoplastic polyurethane, natural rubber, polyurethane rubber, or nylon, and its overall shape can be circular, rectangular, or fan-shaped, and its surface can have irregular curves.

[0035] Please refer to Figure 1 The massage airbag 3 abuts against the support airbag 1. The massage airbag 3 is located on the side of the support airbag 1 away from the seat back 2, and the massage airbag 3 has an air inlet 11. The massage airbag 3 and the support airbag 1 are made of the same material, which can be one or more of thermoplastic polyurethane, natural rubber, polyurethane rubber, or nylon. The massage airbag 3 and the support airbag 1 can be fixed together by high-frequency welding, and the massage airbag 3 and the support airbag 1 have similar shapes.

[0036] Please refer to Figure 1 In order to make the support air bag 1 support the massage air bag 3 more stably, a depression can be formed on the part of the support air bag 1 that contacts the massage air bag 3, and the massage air bag 3 is at least partially placed in the depression to improve the support stability of the support air bag 1 and the massage air bag 3 and prevent the massage air bag 3 from shifting after inflation.

[0037] Please refer to Figure 1 The air tube 4 is independently connected to the air inlet 11 of the support air bag 1 and the air inlet 11 of the massage air bag 3, respectively. The air tube 4 is used to independently inflate and deflate the support air bag 1 and the massage air bag 3. The air tube 4 can be made of rubber, nylon, or polyurethane. The air tube 4 can be fixed along the metal frame or plastic bracket of the seat, such as by using cable ties, clamps, or other fixing devices to fix the air tube 4 to the frame at certain intervals to prevent the air tube 4 from shaking or shifting inside the seat.

[0038] Please refer to Figure 1The air tube 4 can be sealed to the massage air bag 3 and the support air bag 1 via quick connectors. The male and female quick connectors are installed on the air tube 4 and the massage air bag 3 respectively, and the connection can be achieved through a simple plug-and-play operation. Alternatively, it can be connected by heat fusion or adhesive.

[0039] The first air valve is installed on the air pipe 4 that connects to the supporting air bag 1. The first air valve can control the connection and closure between the air pipe 4 and the supporting air bag 1.

[0040] The second air valve is located on the air pipe 4 that connects to the massage air bag 3. The second air valve can control the connection and closure between the air pipe 4 and the support air bag 1.

[0041] The first and second air valves can have the same valve body. The air valve is a key component for controlling the gas entering and leaving the air bag. It can be an electromagnetic air valve or a mechanical air valve. For ease of control, an electromagnetic air valve is preferred.

[0042] The first and second air valves can be made entirely of plastic, such as a valve body made of engineering plastic and a valve core made of pure iron or low-carbon steel. Alternatively, the valve body and valve core can be made of other materials, as long as they can achieve airflow cutoff and flow control.

[0043] Please refer to Figure 1 The massage airbag on the backrest 2 of the seat in this application is divided into two parts: a support airbag 1 and a massage airbag 3. The two are connected by independent air pipes 4 to inflate and deflate. The inflation and deflation states of the massage airbag 3 and the support airbag 1 are controlled by different first and second air valves. The support airbag 1 can increase the height of the massage airbag 3, thereby enhancing the massage effect. In addition, the support airbag 1 can reduce the volume of the massage airbag 3, avoiding the slow inflation and deflation speed caused by the large volume of the massage airbag 3, and ensuring the massage effect.

[0044] Please refer to Figure 1 Meanwhile, the support air bag 1 and massage air bag 3 in this solution can achieve different massage effects by adjusting the inflation state of the support air bag 1.

[0045] When a gentler massage is needed, the support airbag 1 can be partially or completely inflated, resulting in a shorter stroke for the massage airbag 3 after inflation, thus reducing the massage intensity. Alternatively, the support airbag 1 can be fully inflated, and the first air valve can be closed during the massage, allowing the massage airbag 3 to expand to a position further away from the seat back 2, thereby increasing the massage intensity. When a stronger massage is needed, the support airbag 1 and the massage airbag 3 can be inflated and deflated simultaneously, allowing the massage airbag 3 to move a greater distance in a short time and thus providing a stronger massage.

[0046] In some examples, the support airbag can be deflated when not in use, to avoid the support airbag being constantly inflated, which could cause plastic deformation or other phenomena that reduce its lifespan.

[0047] Please refer to Figure 2 In some examples, multiple support airbags 1 are provided, spaced apart on the seat back 2; multiple massage airbags 3 are provided, each corresponding to one of the support airbags 1, with the massage airbag 3 abutting against its corresponding support airbag 1. The multiple support airbags 1 and multiple massage airbags 3 can increase the contact area between the massage airbags 3 and the passenger's back, resulting in a better massage effect.

[0048] In some examples, the number of support airbags 1 and massage airbags 3 can be designed according to the size of the backrest 2, the size of support airbags 1 and massage airbags 3, so that support airbags 1 and massage airbags 3 can provide passengers with a better seat massage effect.

[0049] Please refer to Figure 3 In some examples, multiple support air bags 1 are connected, and all the support air bags 1 form an air inlet 11. The air tube 4 is connected to the air inlet 11 of the support air bags 1. The multiple support air bags 1 share a single air inlet 11, which facilitates the connection and inflation / deflation between the multiple support air bags 1 and the air tube 4.

[0050] Please refer to Figure 2 In some examples, the connection between the support air bags 1 can be integrally formed or they can be connected to each other in pairs. When multiple support air bags 1 are distributed in an array, the arrayed support air bags 1 can form multiple independent cavities in the vertical or horizontal direction, and the multiple support air bags 1 in the vertical or horizontal direction can be connected to each other.

[0051] Please return to the reference. Figure 2 In some examples, multiple massage air bags 3 operate independently, and air pipes 4 are independently connected to the air inlets 11 of each massage air bag 3. Multiple second air valves are configured, each corresponding to one massage air bag 3, and are located on the air pipe 4 connected to the corresponding massage air bag 3. Independent air supply to different massage air bags 3 allows for different inflation / deflation states in different parts of the back, resulting in better localized massage effects.

[0052] In some examples, the air inlets 11 of multiple massage air bags 3 can be identical, and the multiple second air valves can also be identical. The air tube 4 can be provided with an independent interface for each massage air bag 3 to facilitate communication between the air tube 4 and the massage air bag 3.

[0053] Please refer to Figure 2In some examples, the massage airbags 3 are configured with at least three layers, extending along the extension direction of the support airbag 1 and the massage airbags 3. Having at least three layers of massage airbags 3 allows the massage airbags 3 themselves to have a greater length in the direction perpendicular to the seat back 2, thereby increasing the massage intensity of the massage airbags 3.

[0054] In some examples, the massage airbag 3 can have 3 layers, or it can have 4, 5, or other numbers of layers.

[0055] For example, the areas of the massage air bags 3 in different layers can be the same, or the areas of the massage air bags 3 in different layers can gradually decrease from the backrest 2 of the seat towards the massage air bag 3.

[0056] Please refer to Figure 2 In some examples, any two adjacent massage air bags 3 in at least three layers are connected. The connection of at least three layers of massage air bags 3 allows each massage air bag 3 to have only one air inlet 11, which facilitates the arrangement of the air tubes 4 of the massage air bags 3 and reduces the difficulty of installation.

[0057] In some examples, any two massage air bags 3 can be connected by integral molding, or they can be sealed by sewing, bonding, welding or other means.

[0058] In some other examples, at least two cavities are formed in at least three layers of massage airbags 3, and at least two air inlets 11 are provided, such that each cavity has an air inlet 11 in communication with it, thereby further reducing the volume of each individual cavity of the massage airbag 3. When the massage airbag 3 needs to be inflated, multiple air inlets 11 are inflated simultaneously to improve the inflation speed and massage intensity of the massage airbag 3.

[0059] Please refer to Figure 2 In some examples, the air inlet 11 of the massage air bag 3 is located on a layer of massage air bag 3 near the supporting air bag 1. The air tube 4 is usually installed on the backrest 2, and the air inlet 11 is located on the massage air bag 3 near the backrest 2, which facilitates the connection and fixation of the air tube 4 to the massage air bag 3.

[0060] In some examples, the air inlet 11 of the massage air bag 3 can be set on the side wall of the massage air bag 3 at the bottom layer (i.e., the layer near the backrest 2) or on one side bottom wall, both of which can achieve the inflation effect.

[0061] Please refer to Figure 4In some examples, the support airbags 1 are configured as at least two layers, with the at least two layers of support airbags 1 extending along the distribution direction of the support airbags 1 and the massage airbags 3. At least two layers of support airbags 1 allow the support airbags 1 to provide greater support height for the massage airbags 3, thereby increasing the massage force of the massage airbags 3.

[0062] In some examples, the support airbag 1 can be set to two layers, or three layers, or other numbers of layers.

[0063] Please refer to Figure 5 In some examples, along the distribution direction of the support airbag 1 and the massage airbag 3, the massage airbag 3 is projected onto the support airbag 1. The area of ​​the massage airbag 3 is smaller than the area of ​​the support airbag 1, which allows the massage airbag 3 to be stably supported on the support airbag 1.

[0064] In some examples, the size of the massage airbag 3 is smaller than the size of the support airbag 1, which facilitates the stable support of the massage airbag 3 on the support airbag 1. In this case, the size of the massage airbag 3 can be between 45% and 80% of the size of the support airbag 1.

[0065] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0066] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
