Description

Ventilation support integration unit and seat Technical Field

[0001] This invention relates to the technical field of automobile seats, and more particularly to a ventilated support integrated device and a seat. Background Technology

[0002] Existing car seats are typically equipped with ventilated airbags and support airbags, providing a more comfortable user experience for drivers and passengers.

[0003] The primary function of ventilated bags in car seats is to improve seat ventilation and enhance passenger comfort. This typically involves using highly breathable materials, such as 3D knitted mesh or perforated TPU film, to facilitate airflow within the seat. Furthermore, ventilated bags often incorporate an adjustable temperature control system that automatically regulates the seat temperature, providing a more personalized comfort experience.

[0004] A lumbar support airbag is a device that provides support and protection for occupants. It primarily consists of an inflatable airbag structure made of highly elastic and abrasion-resistant materials such as thermoplastic polyurethane (TPU). When lumbar support is needed, the airbag inflates rapidly, providing additional lumbar support and increasing occupant comfort.

[0005] The existing ventilation bags and support air bags are set up independently, which is costly. In addition, the ventilation bags and support air bags need to avoid each other, which limits the further improvement of ventilation and support comfort.

[0006] Therefore, it is necessary to design a ventilation support integrated device and seat that integrates ventilation bags and support air bags into one unit. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a ventilation support integrated device and seat that integrates ventilation bags and support air bags into one unit.

[0008] The technical solution of the present invention provides a ventilation support integrated device, including a support part, a ventilation part, an air pump and a fan. The air pump is connected to the support part, the fan is connected to the ventilation part, the support part and the ventilation part are installed together, and the support part and the ventilation part are not connected to each other. The ventilation part is provided with an air duct. When the support part is inflated, the air duct of the ventilation part is unfolded.

[0009] Furthermore, the support portion is disposed inside the ventilation portion, the support portion includes multiple support air bags, the ventilation portion includes an installation layer and a ventilation layer, the support air bags are disposed between the installation layer and the ventilation layer, and multiple ventilation holes are opened on the ventilation layer, the ventilation holes are staggered from the support air bags;

[0010] When the support air bag is inflated, it expands the mounting layer and the ventilation layer, forming the air duct between them.

[0011] Furthermore, the air pump and the fan can be controlled independently.

[0012] Furthermore, the support airbag includes a waist airbag and a non-waist airbag, wherein the maximum inflation capacity of the waist airbag is greater than the maximum inflation capacity of the non-waist airbag.

[0013] Furthermore, the ventilation section is disposed inside the support section, the ventilation section includes a ventilation channel, the support section is an air bag structure, the support section has ventilation holes, and the ventilation holes communicate with the ventilation channel;

[0014] When the support is inflated, the ventilation channel unfolds and ventilates through the vent holes.

[0015] Furthermore, there are multiple vent holes, and the ventilation section also includes multiple ventilation branch pipes, one end of which is connected to the ventilation channel and the other end of which is connected to the vent holes.

[0016] Furthermore, the support includes a first layer of air bags and a second layer of air bags. The ventilation channel is disposed in the first layer of air bags, the ventilation branch pipe is disposed in the second layer of air bags, and the vent is opened on the second layer of air bags. When the first layer of air bags is inflated, the ventilation channel is opened, and the ventilation channel ventilates through the vent.

[0017] Furthermore, the first layer of air bags may or may not be connected to the second layer of air bags.

[0018] The present invention also provides a seat, including the ventilation support integrated device described in any of the above claims, wherein the ventilation support integrated device is installed inside the seat.

[0019] Furthermore, it also includes a heating layer installed inside the seat and located in front of the ventilation support integration.

[0020] Furthermore, when the heating layer is heated, the support portion is circulated and de-energized; after the heating layer is heated, the ventilation portion ventilates to dissipate heat.

[0021] The above technical solution has the following beneficial effects:

[0022] This invention integrates the ventilation and support components, facilitating interior seat layout, reducing costs, and enhancing both ventilation and support comfort. Furthermore, the support and ventilation components are interconnected; the ventilation component can only deploy and provide ventilation after the support component is inflated.

They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0041] Example 1:

[0042] As shown in Figure 1, the ventilation support integrated device 10 includes a support part 1, a ventilation part 2, an air pump 3 and a fan 4. The air pump 3 is connected to the support part 1, and the fan 4 is connected to the ventilation part 2. The support part 1 and the ventilation part 2 are installed together, and the support part 1 and the ventilation part 2 are not connected to each other. The ventilation part 2 is provided with an air duct. When the support part 1 is inflated, the air duct of the ventilation part 2 is unfolded.

[0043] Specifically, as shown in Figure 1, the ventilation support integrated device 10 includes a support part 1 and a ventilation part 2. The support part 1 is located inside the ventilation part 2 and includes multiple support air bags 11. The ventilation part 2 includes an installation layer 21 and a ventilation layer 22. The support air bags 11 are located between the installation layer 21 and the ventilation layer 22. Multiple ventilation holes 221 are opened on the ventilation layer 22, and the ventilation holes 221 are staggered from the support air bags 11. When the support air bags 11 are inflated, the support air bags 11 expand the installation layer 21 and the ventilation layer 22, forming an air duct between the installation layer 21 and the ventilation layer 22.

[0044] The mounting layer 21 is a closed structure, and the ventilation layer 22 has multiple spaced ventilation holes 221. The ventilation layer 22 and the edge of the mounting layer 21 are connected to form a ventilation section 2, which is connected to the fan 4 through a duct. Multiple support air bags 11 are arranged between the mounting layer 21 and the ventilation layer 22, and the positions of the support air bags 11 are staggered from the ventilation holes 221 to avoid obstructing the ventilation of the ventilation holes 221.

[0045] When the support air bag 11 is not inflated, the thickness of the support air bag 11 is very small, the gap between the mounting layer 21 and the ventilation layer 22 is very small, and the ventilation hole 221 is almost touching the mounting layer 21, which makes the air duct in the ventilation section 2 blocked.

[0046] When ventilation is required, the air pump 3 first inflates the support air bag 11. After inflation, the support air bag 11 expands, opening the gap between the mounting layer 21 and the ventilation layer 22, thereby opening the air duct of the ventilation section 2. Subsequently, the fan 4 blows air into the ventilation section 2, and the ventilation hole 221 blows gas outward. At this time, it is necessary to maintain the pressure of the support air bag 11 to keep the support air bag 11 in an open state.

[0047] When ventilation is not required and only lumbar support for the driver and passengers is needed, only the air pump 3 is turned on to inflate the support air bags 11, and the fan 4 is not turned on.

[0048] When ventilation and support are required at the same time, first turn on the air pump 3 to inflate the support air bag 11, and then turn on the fan 4 for ventilation.

[0049] Optionally, the airbag 11 can be inflated during manufacturing or by an air pump 3 during use.

[0050] Furthermore, the air pump 3 and the fan 4 can be controlled independently.

[0051] Preferably, the air pump 3 and fan 4 can be controlled separately by a central controller, which can control whether to turn on the air pump 3 and fan 4 and for how long, according to different user operation commands.

[0052] Furthermore, the support airbag 11 includes a waist airbag and a non-waist airbag, with the maximum inflation capacity of the waist airbag being greater than that of the non-waist airbag.

[0053] Specifically, the support airbags 11 include multiple airbags, corresponding to the back and waist of the human body respectively. When the user needs to support the waist, more air is inflated into the waist airbags to provide better support. When waist support is not needed, the inflation amount of the waist airbags is reduced.

[0054] Ideally, the waist can also be massaged by controlling the repeated shrinking and expanding of the waist airbag.

[0055] Example 2:

[0056] As shown in Figure 2, the seat includes the ventilation support integrated device 10 in Embodiment 1 and its modifications, and the ventilation support integrated device 10 is installed inside the seat.

[0057] Specifically, the seat includes a sponge layer 30, a foam layer 40, and a back spring 50. A ventilation support integrated device 10 is disposed between the foam layer 40 and the sponge layer 30. The back spring 50 is disposed on the rear side of the foam layer 40, and a fan 4 and an air pump 3 are disposed on the rear side of the back spring 50.

[0058] The sponge layer 30 has through holes corresponding to ventilation holes 221 for ventilation.

[0059] Furthermore, as shown in Figure 2, a heating layer 20 is also included, which is installed inside the seat and located in front of the ventilation support integration device 10.

[0060] The heating layer 20 is located in front of the sponge layer 30 and is used to heat the lower back of the user. The ventilation section 2 can adjust the heating temperature and dissipate heat appropriately to prevent burns to the user.

[0061] Example 3:

[0062] The ventilation support integrated device 10 includes a support part 1, a ventilation part 2, an air pump 3 and a fan 4. The air pump 3 is connected to the support part 1, and the fan 4 is connected to the ventilation part 2. The support part 1 and the ventilation part 2 are installed together, and the support part 1 and the ventilation part 2 are not connected to each other. The ventilation part 2 is provided with an air duct. When the support part 1 is inflated, the air duct of the ventilation part 2 is opened.

[0063] Specifically, as shown in Figure 3, when the support part 1 is not inflated, the entire ventilation support integrated device 10 has a flat structure.

[0064] As shown in Figure 4, the ventilation section 2 is located inside the support section 1. The ventilation section 2 includes a ventilation channel 23. The support section 1 is an air bag structure. A ventilation hole 12 is provided on the support section 1, and the ventilation hole 12 is connected to the ventilation channel 23. When the support section 1 is inflated, the ventilation channel 23 is opened, and the ventilation channel 23 is ventilated through the ventilation hole 12.

[0065] As shown in Figure 5, the support part 1 consists of an upper air bag membrane 15 and a lower air bag membrane 16. The edges of the upper air bag membrane 15 and the lower air bag membrane 16 are welded by high frequency welding. The ventilation hole 12 is opened on the upper air bag membrane 15, and the ventilation channel 23 is connected between the upper air bag membrane 15 and the lower air bag membrane 16.

[0066] Before the support part 1 is inflated, the upper film 15 and the lower film 16 of the air bag are tightly attached to each other, and the ventilation channel 23 is compressed.

[0067] When gas is filled into the support section 1, the upper membrane 15 and lower membrane 16 of the air bag open, and the ventilation channel 23 is opened. The ventilation section 2 can then ventilate through the vent hole 12.

[0068] Preferably, there are multiple vents 12, with one ventilation channel 23 corresponding to multiple vents 12.

[0069] Alternatively, there may be multiple ventilation channels 23, each ventilation channel 23 corresponding to multiple vents 12.

[0070] In this embodiment, when ventilation is required, the air pump 3 first inflates the support part 1, and the upper membrane 15 and lower membrane 16 of the air bag are opened, thereby opening the ventilation channel 23. Subsequently, the fan 4 blows air into the ventilation part 2, and the vent 12 blows gas outward. At this time, it is necessary to maintain the pressure of the support part 1 and keep the support part 1 in an open state.

[0071] When ventilation is not required and only lumbar support for the driver and passengers is needed, only the air pump 3 is turned on to inflate the support part 1, and the fan 4 is not turned on.

[0072] When ventilation and support are required at the same time, first turn on the air pump 3 to inflate the support part 1 and maintain the pressure of the support part 1, and then turn on the fan 4 for ventilation.

[0073] Optionally, the support 1 can be inflated during manufacturing or by an air pump 3 during use.

[0074] Example 4:

[0075] As shown in Figure 6, there are multiple vent holes 12, and the ventilation section 2 also includes multiple ventilation branch pipes 24. One end of the ventilation branch pipe 24 is connected to the ventilation channel 23, and the other end is connected to the vent hole 12. The support section 1 includes a first layer of air bag 13 and a second layer of air bag 14. The ventilation channel 23 is disposed in the first layer of air bag 13, the ventilation branch pipes 24 are disposed in the second layer of air bag 14, and the vent holes 12 are opened on the second layer of air bag 14.

[0076] When the support part 1 is not inflated, the first air bag 13 and the second air bag 14 are flattened, and the ventilation channel 23 and the ventilation branch pipe 24 are also flattened and do not unfold.

[0077] When ventilation is needed, the air pump 3 inflates the first air bag 13, the first air bag 13 unfolds, opening the ventilation channel 23, and after the fan 4 is turned on, the ventilation channel 23 ventilates through the vent hole 12.

[0078] Furthermore, the first layer of airbag 13 is not connected to the second layer of airbag 14.

[0079] When the first air bag 13 is inflated, the second air bag 14 does not deploy. At this time, only one air bag is deployed, providing a certain degree of support for the lower back.

[0080] When enhanced support for the lumbar region is needed, air pump 3 inflates the second air bag 14, which then expands the ventilation branch pipe 24. If simultaneous ventilation is required, fan 4 is turned on, and ventilation channel 23 ventilates through ventilation branch pipe 24 and then through vent hole 12.

[0081] Optionally, the first air bag 13 can be inflated during manufacturing or by an air pump 3 during use.

[0082] Optionally, the first airbag 13 and the second airbag 14 can be connected, so that when the air pump 3 inflates the first airbag 13, the second airbag 14 can also unfold. By adjusting the inflation amount, the support force on the waist can be adjusted. Further, as shown in Figure 7, the support part 1 is composed of an upper airbag membrane 15, a middle airbag membrane 17, and a lower airbag membrane 16. The edges of the upper airbag membrane 15, the middle airbag membrane 17, and the lower airbag membrane 16 are high-frequency welded. The ventilation channel 23 is connected between the middle airbag membrane 17 and the lower airbag membrane 16, and the ventilation branch pipe 24 is connected between the middle airbag membrane 17 and the upper airbag membrane 15. The first airbag 13 is formed between the middle airbag membrane 17 and the lower airbag membrane 16, and the second airbag 14 is formed between the middle airbag membrane 17 and the upper airbag membrane 15. The air bag membrane 17 has a through hole 171, the ventilation channel 23 is directly connected to the through hole 171, one end of the ventilation branch pipe 24 is directly connected to the ventilation hole 12, and the other end is directly connected to the through hole 171.

[0083] The support in this embodiment can provide better support for the waist, and users can adjust the support intensity as needed.

[0084] Example 5:

[0085] As shown in Figure 8, the seat includes the ventilation support integrated device 10 in Embodiments 3 and 4, and the ventilation support integrated device 10 is installed inside the seat.

[0086] The seat in Embodiment 5 integrates the ventilation support integrated device 10 of Embodiments 3 and 4. The ventilation support integrated device 10 of Embodiment 3 corresponds to the back of the human body, and the ventilation support integrated device 10 of Embodiment 4 corresponds to the waist of the human body.

[0087] Furthermore, as shown in Figure 8, a heating layer 20 is also included, which is installed inside the seat and located in front of the ventilation support integration device 10.

[0088] The heating layer 20 can provide heat to the back and waist, increasing comfort. The ventilation section 2 can reduce excess heat or regulate the temperature during ventilation.

[0089] The support for the lower back can also be adjusted by controlling the inflation of the second air bag 14 in Embodiment 4. Alternatively, by repeatedly increasing or decreasing the inflation of the second air bag 14, a massage effect on the lower back can be achieved, which, combined with the heat therapy function of the heating layer 20, provides a therapeutic effect.

[0090] Furthermore, when the heating layer 20 is heated, the support part 1 circulates air in and out, which, together with the heating of the heating layer, plays a therapeutic role; after the heating layer 20 is heated, the ventilation part 2 ventilates to dissipate heat.

[0091] The above description is merely the principle and preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
