Technical Field

[0003] This disclosure relates to the field of automotive seat headrest technology, specifically to an automotive seat massage attached headrest with a pneumatic device, an automotive seat neck heat-simulating massage system, and an automotive seat. Background Technology

[0004] With the increasing popularity of automobiles and people's growing demands for driving and riding comfort, the comfort and functionality of car seats are receiving more and more attention. Traditional car seat headrests typically have a limited function, providing only basic head support.

[0005] On the one hand, people are prone to fatigue and discomfort during long drives or rides, especially in the neck and head. Furthermore, different people have different needs regarding headrest height, firmness, and other aspects, and existing seat headrests often fail to meet these individualized requirements.

[0006] On the other hand, existing car seats usually have soft pillows attached at the connection between the headrest and the backrest. These soft pillows provide some support for the passenger's neck and can improve stiffness and fatigue in the neck. However, based on long-term use, the effect is generally limited and the function is singular. They are not effective in relieving cervical discomfort or driving fatigue.

[0019] In an optional embodiment, the first and second air tubes are welded together using the edges of a TPU film and have internal support ventilation components.

[0020] In an optional embodiment, the first trachea and the second trachea are gear-type tracheas.

[0021] In an alternative embodiment, the second tracheal tube assembly passes through the interior of the headrest bar, and each second tracheal tube in the second tracheal tube assembly is detachable from the other second tracheal tubes.

[0022] Secondly, this disclosure provides a car seat neck-simulating heat-moxibustion massage system, which uses a soft pillow attached to the headrest of the seat as a carrier, and includes a massage component, a heating component, and a control assembly. The massage component is disposed within the soft pillow, and includes a pneumatic massage bladder assembly capable of supporting or massaging the occupant's neck. The heating component is disposed on the side of the soft pillow near the occupant's neck and is correspondingly disposed to the massage component. The control assembly is configured to: firstly, control the heating component to heat up and after a preset time, control the pneumatic massage bladder assembly to inflate and lift up, forcing the heating component to move closer to the occupant's neck to apply thermal compression to the occupant's neck, forming a "top-pressure heat moxibustion" effect on the neck; secondly, control the heating component to stop heating when the pneumatic massage bladder assembly changes from an inflated state to a deflated state.

[0023] In an optional embodiment, the pneumatic massage bag assembly includes a support air bag and a massage air bag. The support air bag is configured as a single-layer air bag, and the massage air bag is disposed on the side of the support air bag near the heating component. Two sets of massage air bags are provided, and the two sets of massage air bags are symmetrically arranged on both sides of the central axis of the support air bag. Each set of massage air bags is configured as a multi-layer air bag that is interconnected, and the airflow connection is offset from the central axis of the massage air bag and closer to the central axis of the support air bag, so that when the multi-layer air bags are inflated, they tend to converge inward.

[0024] In an optional embodiment, a first limiting member is provided between the two sets of massage air bags. The first limiting member is connected to the massage air bags on both sides. The first limiting member is configured to constrain the lateral displacement of the two sets of massage air bags during the inflation process, so that the two sets of massage air bags can be better closed inward.

[0025] In an optional embodiment, the first limiting member is configured as a connecting rib, which is disposed between the bottommost air bags of the two sets of massage air bags and connected to the massage air bags on both sides. The connecting rib can constrain the lateral displacement of the two sets of massage air bags during the inflation process, so that the two sets of massage air bags can better converge inward.

[0026] In an optional embodiment, a second limiting member is provided inside the support air bag. The second limiting member is configured to: constrain the height of the support air bag after it is inflated and raised, and also to cause the surface of the support air bag to tend to be horizontal or near-horizontal after it is inflated and raised.

[0027] In an optional embodiment, the second limiting member is a tension band made of flexible material. The tension band is disposed between the upper and lower diaphragms of the supporting air bag and is fixedly connected to the upper and lower diaphragms. When the supporting air bag is inflated and lifted, the lifting height of the supporting air bag is constrained by the tension band, and the surface of the supporting air bag will gradually tend to be horizontal or near-horizontal.

[0028] In an optional embodiment, the heating component includes at least one heating circuit, which is arranged corresponding to the force application area of ​​the massage component. The heating circuit is formed by bending at least one heating wire in a serpentine pattern. The end of the heating wire is connected to a wiring harness, which is connected to an external power source.

[0029] In an optional embodiment, the control assembly includes a pneumatic adjustment module and a heating adjustment module. The pneumatic adjustment module is configured to control the inflation or deflation of the pneumatic massage bag assembly. The heating adjustment module controls the heating component to heat or stop heating based on the inflation or deflation status of the pneumatic massage bag assembly.

The air source is configured to inflate the pneumatic massage bag assembly; the air distribution valve is configured to regulate the gas flow state; and the controller controls the operation of the air source and the air distribution valve to inflate or deflate the pneumatic massage bag assembly.

[0031] Thirdly, a car seat is provided that includes a neck-simulating heat massage system as described in the first aspect of this disclosure.

[0032] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this disclosure are as follows:

[0033] On one hand, this disclosure proposes a car seat massage pillow with a pneumatic device. This pillow can be attached to the headrest or between the headrest and the seat back, providing users with diverse usage options such as head support or neck support. An airbag assembly is located inside the pillow's cover, and its inflation and deflation states are controlled by the pneumatic component, allowing adjustment of the pillow's firmness and height, further enhancing the seat's comfort and adaptability. The pneumatic device in the pillow allows users to adjust the headrest's position according to their needs, alleviating fatigue from long drives or rides. For example, during driving, when neck discomfort is felt, inflation can increase the headrest's support and reduce neck pressure.

[0034] Furthermore, this disclosure also proposes a car seat neck-simulating heat-moxibustion massage system and a car seat. Its control assembly can control the heating component to operate and begin heating. After a preset heating time is reached, the control module then controls the pneumatic massage bladder assembly to operate. As the pneumatic massage bladder assembly inflates, it drives the heating component to move closer to the occupant's neck, causing the occupant to feel a hot compression, thus producing a "pressure-moxibustion" effect on the neck, thereby improving neck stiffness and fatigue. When the pneumatic massage bladder assembly deflates from the inflated state, the heating component stops heating. Simultaneously, the neck-simulating heat-moxibustion massage system of this disclosure also has the advantages of simple structure, easy assembly, and safe and reliable use, facilitating implementation and widespread application.

[0059] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant disclosure and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the disclosure are shown in the accompanying drawings.

[0060] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] This disclosure discloses a car seat massage pillow with a pneumatic device, a car seat neck heat-simulating massage system, and a car seat, which can support or massage the neck of the occupant, thereby improving the comfort and adaptability of the car seat.

[0062] Please refer to Figures 1-15. This disclosure discloses a car seat massage pillow with a pneumatic device. The car seat includes at least a seat back 10 and a headrest rod 9 disposed on the seat back 10, with a headrest 8 mounted on the headrest rod 9; including:

[0063] The attached pillow cover 1 has a first cavity inside, and the first cavity contains a soft filling 4; the attached pillow cover 1 has an attached pillow bearing surface configured to support the human body; the attached pillow cover 1 can be attached to the seat headrest 8 or the seat headrest rod 9. When attached to the seat headrest rod 9, the attached pillow cover 1 is located between the seat headrest 8 and the seat back 10.

[0064] At least one airbag assembly, the airbag assembly including at least one massage airbag 2 disposed in the first cavity;

[0065] The pneumatic assembly includes an air pump 12 and a control valve 11. The pneumatic assembly is connected to the airbag assembly via an air tube assembly 14 to control the airbag assembly to switch between an inflated state and a deflated state.

[0066] In this embodiment, please refer to Figure 2. The attached pillow cover 1 has an outer covering layer 5 and an inner covering layer 6 along its thickness direction. A first cavity is formed in the inner covering layer 6, and the outer covering layer 5 is located on the side of the inner covering layer 6 away from the first cavity.

[0067] Optionally, the first cavity is filled with a suitable soft padding material 4, such as memory foam or down, to provide comfortable head support. The soft padding material 4 should have a certain degree of elasticity and softness, while maintaining its shape to ensure the stability of the headrest.

[0068] Specifically, please refer to Figure 10. The attached pillow cover 1 has fixing straps 17 on both sides. The ends of the fixing straps 17 are connected to male and female buckles 18 respectively. When the male and female buckles 18 are connected, the attached pillow cover 1 is fixed in the required position. When the attached pillow cover 1 is placed between the seat headrest 8 and the seat back 10 through the fixing straps 17, the gap between the seat back 10 and the seat headrest 8 should be minimized. This can ensure that the airbag component inside the attached pillow cover 1 has a certain support behind the attached pillow cover 1 when it is inflated, thereby improving the sensation of headrest massage.

[0069] In this embodiment, the airbag assembly includes at least one massage airbag 2, which is disposed in the first cavity.

[0070] Optionally, the massage airbag 2 is embedded in the soft filling body 4, or is disposed between the soft filling body 4 and the attached pillow cover 1.

[0071] Specifically, when the massage air bag 2 is located between the soft filling body 4 and the attached pillow cover 1 on either side, or on the corresponding side of the attached pillow bearing surface, the massage air bag 2 needs to be made very soft to reduce the feeling of foreign objects.

[0072] Specifically, an airbag assembly can be set up, as shown in Figure 4, to support the head or neck of the occupant by inflating or deflating or maintaining air pressure. Alternatively, two or more airbag assemblies can be set up inside and placed on both sides of the neck and head to massage the neck or head of the occupant.

[0073] In this embodiment, the pneumatic component includes an air pump 12 and a control valve 11. The pneumatic component is connected to the airbag component through an air tube assembly 14 to control the airbag component to switch between an inflated state and a deflated state.

[0074] Specifically, the pneumatic components should be securely and reliably installed to prevent loosening or damage during vehicle operation. Simultaneously, it should be ensured that the air hoses of the pneumatic components are not subjected to compression or wear to guarantee normal gas transmission. The inflation and deflation of this headrest can be controlled via the vehicle's control panel, remote control, or mobile app. Users can choose different control methods according to their needs for convenient and quick adjustment of the headrest's position. Different inflation and deflation modes, such as manual control and automatic adjustment, can be set to meet different user requirements.

[0075] Specifically, the pneumatic components can be a separate air pump 12 and control valve 11, or an integrated pump and valve air pump.

[0076] Understandably, the following describes the specific usage method: Users can choose to attach the attached pillow cover 1 to the seat headrest 8 or headrest rod 9 according to their needs and preferences. Users can activate the pneumatic assembly via control, which continuously inflates and deflates the massage airbags to achieve the massage function. While the vehicle is in motion, users can enhance their comfort under the massage effect of the airbags and adjust the headrest position at any time according to their comfort level to ensure driving or riding comfort and safety.

[0077] In an optional embodiment, the airbag assembly includes a stiffness-adjustable airbag 21 configured to adjust the stiffness of the attached pillow cover 1.

[0078] Specifically, the width of the firmness adjustment airbag 21 is approximately the same as the width of the attached pillow cover 1. The firmness adjustment airbag 21 is embedded in the soft filling 4, or positioned between the soft filling 4 and the attached pillow cover 1. When the occupant needs to adjust the height, firmness, or support of the headrest, the air pump 12 starts working, delivering air to the firmness adjustment airbag 21, causing it to gradually inflate. The user can adjust the inflation level according to their preference until a satisfactory state is achieved. When additional support is not needed or the headrest height needs to be lowered, the user can deflate the firmness adjustment airbag 21 through a control mechanism, restoring it to its initial state. The firmness adjustment airbag 21 can also maintain pressure to preserve the current firmness of the attached headrest.

[0079] In an optional embodiment, the massage air bag 2 has a support portion configured to support the massage air bag 2 on the side away from the bearing surface of the attached pillow, and the support portion is located between the massage air bag 2 and the hardness adjustment air bag 21.

[0080] Specifically, referring to Figure 2, the massage airbag 2 can be placed behind the soft filling 4, which can be understood as the side away from the occupant, i.e., the side away from the support surface of the headrest. Referring to Figure 3, the massage airbag 2 can also be wrapped inside the soft filling 4, such as being sandwiched between two sponge layers or soft cotton layers. The massage airbag 2 is isolated from the surrounding soft filling 4 by the airbag isolation layer 7. When the massage airbag 2 is placed inside the headrest, it is necessary to isolate the massage airbag 2 from the soft filling 4 through the isolation layer to ensure that the massage airbag 2 does not squeeze the soft filling 4 to one side when it is working, preventing the massage airbag 2 from directly contacting the human body and causing a foreign body sensation.

[0081] It is worth mentioning that the length of the isolation layer should be based on the state of the massage air bag 2 being raised, to avoid the isolation layer tearing when the massage air bag 2 is raised.

[0082] In an optional embodiment, the support is a pressure-holding air bag 3 or a support layer with a soft structure sewn along its edge.

[0083] Specifically, the pressure-holding airbag 3 remains inflated when the airbag assembly is inflated, thus maintaining a certain level of support. The width of the support layer is approximately the same as the width of the massage airbag 2. The support layer can be made of a material with a certain degree of rigidity, such as a felt layer. The area of ​​the support layer is smaller than the size of the attached pillow cover 1. A soft structure filled with soft material is sewn around the support layer with lining fabric to prevent a foreign body sensation when the palm touches the perimeter of the headrest.

[0084] In an optional embodiment, the massage airbag 2 has a plurality of protrusions 22 on the side near the bearing surface of the attached pillow, and the soft filling body 4 has a groove 41 corresponding to each protrusion 22 at the corresponding position of the massage airbag 2. When the airbag assembly is in a deflated state, the protrusions 22 are embedded in the groove 41.

[0085] Specifically, the size of the groove 41 should match the protrusion 22 so that when the massage airbag 2 is deflated, the protrusion 22 can fit precisely into the groove 41 formed on the soft filling 4 by a heat-cutting process. This ensures that the headrest remains flat when not in a massage state, preventing discomfort to the user.

[0086] In actual use, when the passenger's head presses against the attached pillow, please refer to Figure 13. The protrusion 22 protrudes from the groove 41 to ensure that the headrest remains flat when not in a massage state. Figure 12 shows the state when the passenger's head is not pressing against the attached pillow.

[0087] In an optional embodiment, referring to Figures 4 and 5, the air tube assembly 14 includes a first air tube 14 connected to each massage air bag 2 and hardness adjustment air bag 21, and a second air tube group extending from the pneumatic assembly. The second air tube group includes a second air tube 15 corresponding to each first air tube 14. The first air tube 14 and the corresponding second air tube 15 are connected by an air tube docking end 13.

[0088] Specifically, the headrest 8 has a first clearance hole, the attached pillow cover 1 has a second clearance hole, the car seat is provided with an air pipe docking end 13, the air pipe docking end 13 has an air pipe interface 132, the second air pipe 15 connected by the pneumatic component is connected to the first air pipe 14 through the air pipe interface 132 to supply or release air to the massage air bag 2, wherein the first air pipe 14 passes through the second clearance hole, and the second air pipe 15 passes through the first clearance hole.

[0089] In an alternative embodiment, the second tracheal tube group passes through the inside of the headrest rod 9, and each second tracheal tube 15 in the second tracheal tube group can be separated from the other second tracheal tubes 15.

[0090] Specifically, the pneumatic system of the attached pillow cover 1 is connected to the control valve 11 and the air pump 12 installed on the seat via the air pipe assembly 14 to inflate and deflate the airbag assembly. The second air tube assembly, including at least one second air tube 15, passes through the inside of the headrest rod 9. Each first clearance hole fixes the end of the corresponding second air tube 15 that passes through the inside of the seat headrest 8. The attached pillow cover 1 has at least one second clearance hole on the bottom side of the corresponding position of the massage air bag 2. Each second clearance hole is configured to fix the end of the corresponding first air tube 14 inside the attached pillow cover 1. Referring to Figures 14 and 15, the second air tube assembly can be in the form of a tearable air tube. The second air tubes 15 are connected by a weak structure that is easy to disassemble, so that each second air tube 15 can be separated from the other second air tubes 15. This allows the middle part of the second air tube 15, that is, the part that passes through the headrest rod 9, to remain connected, so that the second air tube 15 can easily pass through the headrest rod 9. Similarly, the first air tube 14 can also use this kind of easily disassembled air tube.

[0091] Specifically, please refer to Figure 4. The pneumatic assembly can form a connecting air path through the air pipe docking end 13 and the air outlet of the seat headrest 8 of the entire chair, and connect to the relevant control air path of the pneumatic control valve group inside the entire chair. Please refer to Figure 11, or a separate pneumatic device can be used independently.

[0092] In an optional embodiment, referring to Figures 6 and 7, the first air pipe 14 and the second air pipe 15 are welded together using the edge of a TPU film, and the first air pipe 14 and the second air pipe 15 are provided with supporting ventilation components.

[0093] Specifically, the TPU membrane possesses excellent flexibility, abrasion resistance, and airtightness, ensuring that gas does not leak during transmission. During the welding process to form the second gas tube 15, welding quality must be guaranteed to ensure the gas tube's airtightness.

[0094] Optionally, the support ventilation component can be made of lightweight plastic or metal, and its function is to provide support within the air tube to prevent excessive deformation of the second air tube 15 during inflation and deflation. Simultaneously, the support ventilation component also serves a ventilation function, ensuring smooth gas flow within the air tube.

[0095] Alternatively, referring to Figure 6, the shape of the supporting ventilation component can be like the perforated tube 151; referring to Figure 7, the shape of the supporting ventilation component can be like the rhomboid support strip 152, etc.

[0096] In an optional embodiment, the first trachea 14 and the second trachea 15 are gear-type tracheas.

[0097] Specifically, please refer to Figure 5. The second air pipe 15 is connected to the air pump 12 of the seat. To prevent the second air pipe 15 or the first air pipe 14 from becoming blocked, the first air pipe 14 and the second air pipe 15 can use a gear tube, which can effectively reduce the risk of blockage.

[0098] Optionally, as shown in Figure 8, the airway connection end 13 is detachably provided with a hook-and-lock member 131, which is configured to fix the attached pillow cover 1 to the seat headrest 8.

[0099] Specifically, during use, after the user hangs the attached pillow cover 1 on the seat headrest 8, it is secured by the hook-and-lock device 131 to prevent the attached pillow cover 1 from shaking or falling off while the vehicle is in motion. When it is necessary to remove the attached pillow cover 1, the user only needs to release the lock of the hook-and-lock device 131 to easily remove the attached pillow cover 1.

[0100] Optionally, the pneumatic function of the attached pillow cover 1 can exist in conjunction with the pneumatic function related to the seat, or it can exist independently. The attached pillow cover 1 can be provided with an air pump 12 and a control valve 11, or an integrated pump and valve air pump can be selected. The integrated air pump structure can reduce the installation area and realize the function of adjusting the firmness or massage.

[0101] Optionally, as shown in Figure 9, to prevent the attached pillow cover 1 from collapsing after use, a shaped strip 16 for shape restoration can be sewn around the four edges of the attached pillow cover 1. The shaped strip 16 can be located inside or outside the first cavity. The shaped strip 16 can be made of plastic strip with good toughness and a diameter of 2-4mm.

[0102] In summary, this disclosure presents a car seat massage pillow with a pneumatic device. This pillow can be attached to the headrest 8 or between the headrest 8 and the seat back 10, providing users with diverse usage options such as head support or neck support. The airbag assembly is located inside the pillow's outer cover 1, and its inflation and deflation states are controlled by the pneumatic component, allowing adjustment of the pillow's firmness and height, further enhancing the seat's comfort and adaptability. The pneumatic device in the pillow allows users to adjust the headrest's position according to their needs, alleviating fatigue from long drives or rides. For example, during driving, when neck discomfort is felt, inflation can increase the headrest's support and reduce neck pressure.

[0103] Please refer to Figures 16-23. This disclosure also proposes a car seat neck heat-simulated massage system, which uses a soft pillow 22 attached to the headrest 21 as a carrier. The neck heat-simulated massage system includes:

[0104] Massage component 23, heating component 24, and control assembly 25,

[0105] The massage component 23 is disposed inside the attached soft pillow 22. The massage component 23 includes a pneumatic massage bag assembly 231 that can support or massage the neck of the occupant. The heating component 24 is disposed on the side of the attached soft pillow 22 near the neck of the occupant and is disposed corresponding to the massage component 23.

[0106] Control assembly 25 is configured as follows:

[0107] First, after the heating component 24 heats up and reaches the preset time, the pneumatic massage bag group 231 is inflated and pushed up, forcing the heating component 24 to move closer to the occupant's neck, so as to apply heat to the occupant's neck and form a "top pressure heat moxibustion" on the neck.

[0108] Secondly, when the pneumatic massage bag assembly 231 changes from an inflated state to a deflated state, the heating component 24 is controlled to stop heating.

[0109] Understandably, based on the above configuration, the neck simulated heat moxibustion massage process is as follows: First, the control assembly 25 controls the heating component 24 to work and start heating. After the preset heating time is reached, the control module then controls the pneumatic massage bag assembly 231 to work. As the pneumatic massage bag assembly 231 inflates and rises, it will drive the heating component 24 to move closer to the occupant's neck. The occupant's neck will feel the heat compression, thereby producing the effect of "top pressure heat moxibustion" on the neck, which can improve the stiffness and soreness of the occupant's neck. When the pneumatic massage bag assembly 231 changes from the inflated state to the deflated state, the heating component 24 stops heating.

[0110] In an optional embodiment, the attached soft pillow 22 is attached to the headrest 21 of the car seat. The connection between the soft pillow 22 and the headrest 21 is not limited to being tied with a strap or attached with Velcro. The outer side of the attached soft pillow 22 is a lining cover layer 221, and the inner core 222 is filled with cotton wool. The inner core 222 has a space 223 for accommodating the massage component 23.

[0111] In an optional embodiment, the control assembly 25 includes a pneumatic adjustment module 251 and a heating adjustment module 252. The pneumatic adjustment module 251 is configured to control the inflation or deflation of the pneumatic massage bag assembly 231. The heating adjustment module 252 can control the heating component 24 to heat or stop heating based on the inflation or deflation state of the pneumatic massage bag assembly 231.

[0112] In an optional embodiment, the pneumatic dispensing module 251 includes an air source 2511, an air distribution valve 2512, and a controller 2513. The air source 2511 is preferably an air pump 2514, which is configured to inflate the pneumatic massage bag assembly 231. The air distribution valve 2512 is configured to regulate the gas flow state. The controller 2513 controls the operation of the air source 2511 and the air distribution valve 2512 to inflate or deflate the pneumatic massage bag assembly 231.

[0113] In an optional embodiment, the air tube 212 extends from the controller 2513 and passes through the headrest rod 211, and then extends from the headrest rod 211 to the headrest 21. A quick-connect plug 213 connects the attached soft pillow 22 and the headrest 21, and the air passage between the pneumatic massage bag assembly 231 and the air pump 2514 is achieved through the quick-connect plug 213. The quick-connect plug 213 is a conventional setting in the art and will not be described in detail here.

[0114] In an optional embodiment, the pneumatic massage bag assembly 231 includes a support air bag 2311 and a massage air bag 2312. The support air bag 2311 is configured as a single-layer air bag. The massage air bag 2312 is disposed on the side of the support air bag 2311 near the heating component 24. Two sets of massage air bags 2312 are provided, and the two sets of massage air bags 2312 are symmetrically arranged on both sides of the central axis of the support air bag 2311.

[0115] A connecting diaphragm 232 is provided on the side of the two sets of massage air bags 2312 that are far apart from each other. The end of the connecting diaphragm 232 that is far away from the massage air bag 2312 is connected to the support air bag 2311. The massage air bag 2312 and the support air bag 2311 are connected in this way. The connecting diaphragm 232 is made of TPU material.

[0116] Each massage airbag 2312 is configured as a multi-layered airbag that is interconnected, and the airflow connection 233 is offset from the central axis of the massage airbag 2312 and closer to the central axis of the support airbag 2311, so that when the multi-layered airbags are inflated, they tend to converge inward.

[0117] Optionally, in this embodiment, the multi-layer air bag is preferably three layers. In actual selection, it should be set according to the actual needs of the attached soft pillow 22.

[0118] In an optional embodiment, a first limiting member 26 is provided between the two sets of massage air bags 2312. The first limiting member 26 is configured as a connecting rib 261. The connecting rib 261 is located between the bottommost air bags of the two sets of massage air bags 2312 and is connected to the massage air bags 2312 on both sides. The connecting rib 261 can restrain the lateral displacement of the two sets of massage air bags 2312 during the inflation process, so that the two sets of massage air bags 2312 can better converge inward to better fit the occupant's neck.

[0119] In an optional embodiment, a second limiting member 27 is provided inside the support air bag 2311. The second limiting member 27 is a tension band 271 made of flexible material. The tension band 271 is disposed between the upper diaphragm and the lower diaphragm of the support air bag 2311 and is fixedly connected to the upper diaphragm and the lower diaphragm. When the support air bag 2311 is inflated and lifted, the lifting height of the support air bag 2311 is constrained by the tension band 271, and the surface of the support air bag 2311 will gradually tend to be horizontal or near-horizontal.

[0120] It should be noted that, as explained below regarding the horizontal or near-horizontal design, the tensioning strap 271 prevents the support airbag 2311 from over-expanding, i.e., compresses the expansion height of the support airbag 2311. This also reduces the surface curvature of the diaphragm after the support airbag 2311 is lifted, causing the surface of the support airbag 2311 to gradually approach a horizontal or near-horizontal state. The main purpose of this design is to weaken the tendency of the massage airbag 2312 to expand laterally outward when the support airbag 2311 is lifted.

[0121] In an optional embodiment, the heating component 24 includes at least one heating circuit, which is arranged corresponding to the force application area of ​​the massage component 23. The heating circuit is formed by bending at least one heating wire 241. The heating wire 241 is distributed in a serpentine pattern and is specifically sewn onto the inner lining covering layer 221 of the attached soft pillow 22. The end of the heating wire 241 is connected to a wiring harness 242, which is connected to an external power source. In practical applications, after the heating wire 241 and the wiring harness 242 are connected, they are connected to the vehicle's electrical system. The vehicle's electrical system is well known to those skilled in the art and will not be described in detail here.

[0122] It should be noted that, based on the above configuration, the massage configuration of the heat therapy massage system has two modes: Mode 1 and Mode 2. Mode 1 of the massage configuration of the heat therapy massage system is as follows:

[0123] Mode 1: The support airbag 2311 is not inflated, and the massage airbags 2312 on both sides are inflated or deflated at the same time; or the support airbag 2311 is inflated, and the massage airbags 2312 on both sides are inflated or deflated at the same time.

[0124] The following are the corresponding heat massage methods in this mode:

[0125] Firstly, the support airbag 2311 inflates for 7.0 seconds, with a pressure limit of 30 kPa, and maintains pressure continuously; the massage airbags 2312 on both sides inflate simultaneously for 3.0 seconds, and then simultaneously deflate for 3.0 seconds. Then the massage airbags 2312 on both sides inflate again simultaneously for 3.0 seconds, and then simultaneously deflate... This cycle repeats. During the cycle, the massage airbags 2312 on both sides will repeatedly press against the heating component 24, ultimately achieving a relatively gentle pressure heating massage.

[0126] Secondly: The support airbag 2311 inflates for 7.0 seconds, with a pressure limit of 30 kPa, and maintains pressure continuously; the massage airbags 2312 on both sides inflate simultaneously for 3.0 seconds, then simultaneously deflate for 1.0 second, then simultaneously inflate again for 1.0 second, then simultaneously deflate for 1.0 second, then simultaneously inflate again for 1.0 second, and so on, repeating this short-frequency cycle three times, then simultaneously deflate for 3.0 seconds, then simultaneously inflate again for 3.0 seconds... and so on. During the cycle, the massage airbags 2312 on both sides will repeatedly press against the heating component 24, ultimately achieving a relatively fast-paced press-heat massage.

[0127] It should be noted that the second mode of massage configuration for the heat therapy massage system is as follows:

[0128] Mode 2: The support airbag 2311 is not inflated, and the massage airbags 2312 on both sides are not inflated or deflated at the same time; or the support airbag 2311 is inflated, and the massage airbags 2312 on both sides are not inflated or deflated at the same time.

[0129] The following are the corresponding heat massage methods in this mode:

[0130] Firstly, the support airbag 2311 inflates for 7.0 seconds, with a pressure limit of 30 kPa, and maintains that pressure continuously. Then, the left massage airbag 2312 begins to inflate first, with an inflation time of 3.0 seconds, followed by deflation for 3.0 seconds. Simultaneously, the right massage airbag 2312 inflates for 3.0 seconds, followed by deflation for 3.0 seconds. This cycle repeats, with the massage airbags 2312 on both sides pressing against the heating component 24 from left to right, ultimately achieving alternating left and right pressure heating massage.

[0131] This disclosure also proposes a car seat, which includes a seat cushion 28 and a backrest 29. Both the backrest 29 and the seat cushion 28 include a foam structure 210 and a cover 11. A soft pillow 22 is attached to the headrest 21 of the backrest 29. The soft pillow 22 is equipped with the neck heat-simulating massage system of the above embodiment 1. The neck heat-simulating massage system can generate a "top pressure heat moxibustion" effect on the neck of the passenger, thereby improving the stiffness and fatigue of the neck. In addition, the soft pillow 22 can also be set in other positions of the seat cushion 28 or the backrest 29.

[0132] In summary, the present disclosure discloses a car seat neck heat-simulating massage system and a car seat. The control assembly 25 controls the heating component 24 to work and start heating. After the preset heating time is reached, the control module controls the pneumatic massage bag assembly 231 to work. As the pneumatic massage bag assembly 231 inflates and rises, it will drive the heating component 24 to move closer to the occupant's neck. The occupant's neck will feel the heat compression, thereby producing the effect of "pressure heat moxibustion" on the neck, thereby improving the stiffness and fatigue of the occupant's neck. When the pneumatic massage bag assembly 231 changes from the inflated state to the deflated state, the heating component 24 stops heating.
