[0002] With the development of car seat technology, smart cars have gradually become the new favorite of the market. These cars can not only provide smart functions such as navigation, automatic parking and emergency braking, but also begin to pay attention to the riding experience of passengers. Smart cars with seat comfort systems can provide passengers with a more relaxing and pleasant driving / travel experience. These seat comfort systems are usually pneumatic systems. The air bags installed inside the seat skin can provide more comprehensive support for the human body. By increasing the area of ​​contact with the body, the body pressure is more evenly dispersed, reducing the need for support on the spine, thereby reducing musculoskeletal pressure, and providing passengers with a more comfortable riding experience.

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0027] It should be noted that when an element is described as being "fixed to" another element, it may be directly on the other element, or one or more elements may be located therebetween. When an element is described as being "connected to" another element, it may be directly connected to the other element, or one or more elements may be located therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0028] In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] An embodiment of the present application provides a means of transport, which may be any means of transport that can be provided with the vehicle seats shown below, for example, the means of transport may be a car, a van, a truck, etc.

[0030] The present application also provides a car seat 1000, see Figure 1 The automobile seat 1000 includes an air bag assembly 100, a seat back 200, an air source 300, a controller 400, a pressure collector 500, a seat cushion 600 and a valve body (not shown). The automobile seat 100 is provided with a central axis L1. The seat back 200 is connected to the seat cushion 600. When the occupant sits on the seat cushion 600, the seat back 200 is used to bear the pressure of the occupant's back and waist. The air bag assembly 100 is arranged on the seat back 200. The air bag assembly 100 is used to provide a comfortable massage experience for the occupant's back. The air bag assembly 100 is connected to the air source 300 through the valve body. The controller 400 is connected to the valve body. The controller 400 is used to control the air source 300 through the valve body to inflate the air bag assembly 100. The pressure collector 500 is used to provide sensing data when the occupant acts on the automobile seat 1000.

[0031] It is worth noting that, due to the different body shapes of human bodies, the influence of the airbag assembly 100 on the back support is greater than that on the waist, so the airbag assembly 100 corresponds to the back of the occupant.

[0032] For the above-mentioned air bag assembly 100, please refer to Figure 1 and Figure 2The airbag assembly 100 includes a first airbag 10, a second airbag 20, a plurality of third airbags 30 and a plurality of fourth airbags 40. The first airbag 10, the second airbag 20, the plurality of third airbags 30 and the plurality of fourth airbags 40 are all connected to the gas source through the valve body, so as to control the inflation time and / or inflation amount of the first airbag 10, the second airbag 20, the plurality of third airbags 30 and the plurality of fourth airbags 40 respectively. The plurality of third airbags 30 are fixed to the first airbag 10, the plurality of fourth airbags 40 are fixed to the second airbag 20, the plurality of third airbags 30 and the plurality of fourth airbags 40 are symmetrically arranged about the central axis L1, and among the plurality of third airbags 30, the third airbags 30 that are farther away from the seat cushion 600 have a greater distance from the central axis L1. That is, it is equivalent to that the first airbag 10 and the second airbag 20 in the airbag assembly 100 are arranged in an inverted "eight" shape on the seat back 200 of the car seat 1000. Due to the arrangement of multiple third airbags 30 and multiple fourth airbags 40, different third airbags 30 and fourth airbags 40 can be combined to be inflated, so as to act on the occupants, and the backs of occupants with different heights can be accurately massaged; through the combination of the third airbag 30 and the fourth airbag 40 for inflation and deflation, the backs of occupants with different weights can also be accurately massaged, and the user experience is good.

[0033] In addition, since each third airbag 30 is connected to the air source 300 through the valve body, the inflation time and / or inflation amount of each third airbag 30 can be controlled by the air source 300 and the valve body respectively; similarly, since each fourth airbag 40 is connected to the air source 300 through the valve body, the inflation time and / or inflation amount of each fourth airbag 40 can be controlled by the air source 300 and the valve body respectively; through this setting, different third airbags 30 can have different inflation amounts, that is, different third airbags 30 can have different inflated heights, and different fourth airbags 40 can have different inflation amounts, that is, different fourth airbags 40 can have different inflated heights, so that the inflation amounts of multiple third airbags 30 and multiple fourth airbags 40 can match the back curves of different occupants, thereby improving user experience.

[0034] It is worth noting that the first air bag 10 may also be provided with a first air port 12 to communicate with the valve body and the air source 300 through the first air port 11. The second air bag 20 may also be provided with a second air port 22 to communicate with the valve body and the air source 300 through the second air port 22. The plurality of third air bags 30 may be provided with a third air port 31 to communicate with the valve body and the air source 300 through the third air port 31. The plurality of fourth air bags 40 may be provided with a fourth air port 41 to communicate with the valve body and the air source 300 through the fourth air port 41.

[0035] It is worth noting that the first airbag 10 and the second airbag 20 are arranged in an inverted "eight" shape on the seat back 200 of the car seat 1000, so that the first airbag 10, the second airbag 20, the plurality of third airbags 30 and the plurality of fourth airbags 40 can act on the two shoulder blades of the back of the occupant to achieve massage and relaxation of the shoulder blade area of ​​the occupant. This design not only improves the pertinence of the massage, but also the inverted "eight" shape can effectively disperse the back pressure of the occupant and reduce the discomfort that may be caused by long-term sitting in the car seat 1000.

[0036] It is worth noting that the central axis L1 of the car seat 1000 is an important ergonomic concept, which refers to a reference line in the design of the car seat 1000, which is used to ensure that the various parts of the car seat 1000 are aligned with the spine and the center line of the body to provide optimal comfort and safety. Ergonomics puts forward the theory of the central axis of the human body, believing that the central axis is the general hub of human health, controls the dynamic balance of the human body, and coordinates the relationship between man and nature and the human body itself. Considering the central axis during design can help determine the appropriate balance point, allowing users to use the product or space in a more comfortable posture and more intuitive operation. In the design of the car seat 1000, the central axis L1 is used to ensure that the various parts of the car seat 1000 are aligned with the spine and the center line of the body. For example, in the design of some car seats, the center of the car seat runs through HUD (Head-Up Display, HUD for short, is a display technology that projects information directly into the user's field of vision, allowing the user to view information while keeping his sight forward), a flip instrument screen, a three-spoke D-shaped steering wheel, and a sports-style car seat 1000. When the user sits in the main driving seat, the central axis of the person coincides with the technological driving axis, and both the movement of the line of sight and the driving operation can conform to the body's intuition and habits.

[0037] It is worth noting that, in some embodiments, the number of the third airbags 30 is equal to the number of the fourth airbags 40 .

[0038] It is worth noting that, in some embodiments, the number of the third airbags 30 is three, and the number of the fourth airbags 40 is three. That is, the three third airbags 30 are distributed in the first airbag 10, and the three fourth airbags 40 are distributed in the second airbag 20, so that when the three third airbags 30 and the three fourth airbags 40 are used in combination, the backs of passengers with different height sizes can be accurately massaged.

[0039] For details, please refer to Figure 1The plurality of third airbags 30 include a left first airbag 1, a left second airbag 2, and a left third airbag 3, which are sequentially arranged away from the seat cushion 600; the plurality of fourth airbags 40 include a right first airbag 4, a right second airbag 5, and a right third airbag 6, which are sequentially arranged away from the seat cushion 1000; under the first preset condition, the controller 400 is used to control the gas source 300 to inflate the left second airbag 2, the left third airbag 3, the right second airbag 5, and the right third airbag 6; under the second preset condition, the controller 400 is used to control the gas source 300 to inflate the left second airbag 2, the left third airbag 3, the right second airbag 5, and the right third airbag 6. The air source 300 inflates the left third airbag 3 and the right third airbag 6; under the third preset condition, the controller 400 is used to control the air source 300 to inflate the left second airbag 2 and the right second airbag 5; under the fourth preset condition, the controller 400 is used to control the air source 300 to inflate the left first airbag 1, the left second airbag 2, the right first airbag 4 and the right second airbag 5; under the fifth preset condition, the controller 400 is used to control the air source 300 to inflate the left first airbag 1 and the right first airbag 4.

[0040] It is worth noting that the first preset condition, the second preset condition, the third preset condition, the fourth preset condition and the fifth preset condition correspond to occupants with different heights and weights. For example, the first preset condition corresponds to an occupant who is tall and fat, the second preset condition corresponds to an occupant who is tall and medium weight, the third preset condition corresponds to an occupant who is medium height and medium weight, the fourth preset condition corresponds to an occupant who is medium height and fat, and the fifth preset condition corresponds to an occupant who is short but of any weight.

[0041] It is worth noting that the number of the third airbags 30 or the number of the fourth airbags 40 can be set to be more than three, so as to more accurately match occupants of different body types (including height and weight).

[0042] It is worth noting that after analyzing the sensing data collected by the pressure collector 500, the controller 400 classifies the occupants according to their body types (including height and weight), and then matches the first preset condition, the second preset condition, the third preset condition, the fourth preset condition and the fifth preset condition, so that the third airbag 30 and the fourth airbag 40 act in combination on the occupants, that is, the left first airbag 1, the left second airbag 2, the left third airbag 3, the right first airbag 4, the right second airbag 5 and the right third airbag 6 act in combination on the occupants.

[0043] It is worth noting that the method of matching the first preset condition, the second preset condition, the third preset condition, the fourth preset condition and the fifth preset condition is not limited to the above discussion, and there may be other methods. For example, after the occupant sits on the seat cushion 600, he manually enters the height and weight data to match the first preset condition, the second preset condition, the third preset condition, the fourth preset condition and the fifth preset condition; or, after the occupant sits on the seat cushion 600, he manually selects the first preset condition, the second preset condition, the third preset condition, the fourth preset condition and the fifth preset condition.

[0044] It is worth noting that, in some embodiments, see Figure 3 , the first airbag 10 is bent in the direction away from the second airbag 20, and the connecting line of the plurality of the third airbags 30 protrudes toward the central axis L1. Since the plurality of third airbags 30 and the plurality of fourth airbags 40 are arranged symmetrically about the central axis L1, the connecting line of the plurality of fourth airbags 40 protrudes toward the central axis L1. With this arrangement, since the first airbag 10 and the second airbag 20 are equivalent to being arranged in an inverted "eight" shape on the seat back 200 of the car seat 1000, the bent first airbag 10 and the bent second airbag 20 have good matching with the shape of the two shoulder blades of the occupant, which can significantly enhance the massage and relaxation experience of the occupant.

[0045] It is worth noting that, in some embodiments, the first airbag 10 is bent to form a first bending point 13, and the third airbag 30 located in the middle is arranged at the first bending point 13; the second airbag 20 is bent to form a second bending point 23, and the fourth airbag 40 located in the middle is arranged at the second bending point 23. Through this arrangement, the arrangement of the plurality of third airbags 30 and the arrangement of the plurality of fourth airbags 40 are more in line with the shape of the two shoulder blades of the occupant, thereby providing more precise support and massage for the back of the occupant. In addition, the inflation time and / or inflation amount of the plurality of third airbags 30 and the plurality of fourth airbags 40 can be adjusted according to the specific body shape (including height and weight) of the occupant, so as to achieve the best comfort and relaxation effect.

[0046] It is worth noting that, in some embodiments, see Figure 4The third airbag 30 includes multiple layers of first sub-airbags 301, which are stacked on the first airbag 10, and one of the first sub-airbags 301 is connected to the gas source 300 through the valve body; the fourth airbag 40 includes multiple layers of second sub-airbags 401, which are stacked on the second airbag 20, and one of the second sub-airbags 401 is connected to the gas source 300 through the valve body. Through this arrangement, it is convenient to control the bulging height of the third airbag 30 by the inflation time and / or inflation amount, and it is convenient to control the bulging height of the fourth airbag 40 by the inflation time and / or inflation amount.

[0047] It is worth noting that the multiple layers of the first sub-air bags 301 can be interconnected, or the multiple layers of the first sub-air bags 301 can be closed to each other; similarly, the multiple layers of the second sub-air bags 401 can be interconnected, or the multiple layers of the second sub-air bags 401 can be closed to each other.

[0048] It is worth noting that, in some embodiments, the third air port 31 is located in a layer close to the first air bag 10 among the multiple layers of the first sub-air bag 301, and the fourth air port 41 is located in a layer close to the second air bag 20 among the multiple layers of the second sub-air bag 401, so as to facilitate the inflation and deflation of the multiple layers of the first sub-air bag 301 and the inflation and deflation of the multiple layers of the second sub-air bag 401.

[0049] The gas source 300 is used to provide gas to the first airbag 10, the second airbag 20, the third airbags 30, and the fourth airbags 40 to inflate them, thereby supporting or massaging the occupants. The gas source 300 can be any device that can provide gas.

[0050] The pressure collector 500 is used to provide sensing data when the occupant acts on the car seat 1000. Specifically, the pressure collector 500 is arranged on the seat back 200, and is used to provide back sensing data when the occupant's back acts on the seat back 200. The pressure collector 500 is also arranged on the seat cushion 600, and is used to provide hip and leg sensing data when the occupant's hip and leg act on the seat cushion 600; the pressure collector 500 is also used to provide waist sensing data when the occupant's waist acts on the seat back 200.

[0068] The present application embodiment provides an adaptive support method for a car seat, see Figure 6 , the method comprises the following steps:

[0069] Step S10, obtaining back sensing data of the occupant acting on the pressure sensing pad.

[0070] The pressure sensing pad is arranged on the seat back of the car seat, and the pressure sensing pad corresponds to the back of the occupant. When the occupant sits on the car seat and leans on the seat back and applies pressure to the pressure sensing pad, the pressure sensing pad generates back sensing data, for example, the back sensing data includes electrical signals of each sensing point on the pressure sensing pad (including but not limited to voltage, current, capacitance, resistance, etc.), for example, the back sensing data includes the coordinates of each sensing point on the pressure sensing pad, for example, the back sensing data includes the coordinates of the acquired electrical signals.

[0071] Since different occupants have different skeletons, heights and weights, the pressures they apply to each sensing point of the pressure sensing pad are different, and the back sensing data generated by the pressure sensing pad are different. The occupant's back can be graded according to the different back sensing data to obtain the occupant's body shape grade.

[0072] In addition, for passengers of different age groups (such as adults and children), their bones, heights and weights are more different, and they are unique and cannot be replicated. Therefore, the back sensing data applied by passengers of different age groups to the pressure sensing pad are very different, and ultimately the adaptive support method for car seats provided in the embodiment of the present application has good accuracy.

[0073] Step S20, processing the back sensing data to obtain pressure data.

[0074] The pressure data is formed by converting the back sensing data.

[0075] When the passenger uses the car seat and applies pressure to the pressure sensing pad, some sensing points on the pressure sensing pad will generate obvious electrical signals (such as voltage, current, capacitance, resistance, etc.), and the signals of the corresponding areas being compressed can be displayed on the host computer. The signals of the pressure at these sensing points constitute the pressure data.

[0076] Since different passengers have different skeletons, heights and weights, the pressures they apply to the various sensing points of the pressure sensing pad are different, and thus the back sensing data generated by the pressure sensing pad are different, and the corresponding converted pressure data are different.

[0077] Step S30: estimating the body shape of the occupant according to the pressure data.

[0078] The pressure data may be in various forms, for example, the pressure data may include a pressure distribution diagram.

[0079] When the passenger uses the car seat, he applies pressure to the pressure sensing pad, and the multiple sensing points of the pressure sensing pad generate back sensing data, which are then converted into multiple pressure values ​​and coordinates corresponding to the back sensing data generated by the multiple sensing points. After the multiple pressure values ​​are amplified and processed by analog-to-digital conversion, the pressure distribution map can be generated in the image generator.

[0080] It should be noted that the pressure distribution map is a two-dimensional map showing the pressure values ​​of each sensing point. Each pixel in the pressure distribution map corresponds to a pressure value of a sensing point. The pressure distribution map can be a color map or a grayscale map.

[0081] When the pressure distribution map is obtained, the outline and size of the pressure distribution map are then obtained.

[0082] In some embodiments, the contour of the pressure distribution diagram is the back contour of the occupant. One way to obtain the back contour is to extract the contour position corresponding to the pressure value greater than a preset pressure threshold based on binarization based on the pressure values ​​and positions of multiple sensing points; and use connectivity detection to segment and form the back contour based on the contour position.

[0083] The step of estimating the body shape of the occupant according to the pressure data in step S30 is specifically: determining the body shape of the occupant according to the outline and size of the pressure distribution diagram.

[0084] Since different passengers have different body types (including height and weight), after they apply force to the pressure sensing pad, the back sensing data generated at multiple sensing points of the pressure sensing pad are different, so the contour and size of the pressure distribution diagram in the pressure data formed by processing are different. It can be understood that the heavier the passenger is, the wider the contour of the pressure distribution diagram is, and the larger its size is; similarly, the taller the passenger is, the farther the contour of the pressure distribution diagram is from the seat cushion, so the body type (including height and weight) of the passenger can be determined based on the contour and size of the pressure distribution diagram.

[0085] Step S40, matching the body size estimation result of the occupant with a preset body size classification standard to obtain the body size grade of the occupant.

[0086] In some embodiments, the preset body shape classification standards include tall height and fat weight, tall height and medium weight, tall height and thin weight, medium height and fat weight, medium height and medium weight, medium height and thin weight, short height and fat weight, short height and medium weight, and short height and thin weight. The step of matching the body shape estimation result of the occupant with the preset body shape classification standards to obtain the body shape grade of the occupant includes: matching the body shape estimation result of the occupant with the nine grades of tall height and fat weight, tall height and medium weight, tall height and thin weight, medium height and fat weight, medium height and medium weight, medium height and thin weight, short height and fat weight, short height and medium weight, and short height and thin weight to obtain the body shape grade of the occupant.

[0087] It is worth noting that the classification method of the preset body shape grading standard is not limited to the above-mentioned tall and fat, tall and medium weight, tall and thin, medium height and fat, medium height and medium weight, medium height and thin, short height and fat, short height and medium weight, short height and thin, but there may be other classification methods; for example, too tall and fat, too tall and slightly fat, too tall and medium weight, too tall and medium weight, too tall and thin, too tall and thin, slightly tall and fat, slightly tall and slightly fat, slightly tall and medium weight, slightly tall and thin, slightly tall and thin, medium height but any weight, slightly short height but any weight, too short height but any weight.

[0088] See also Figure 7Step S40, i.e., matching the body shape estimation result of the occupant with the preset body shape classification standard to obtain the body shape grade of the occupant, comprises: step S401, scoring the weight estimation result according to a preset scoring mechanism to obtain a weight score; step S402, scoring the height estimation result according to the preset scoring mechanism to obtain a height score; step S403, obtaining the body shape grade of the occupant according to the product of the weight score and the first weight and the product of the height score and the second weight.

[0089] For example, the first weight is 0.3 and the second weight is 0.7, and the body size grade of the occupant can be obtained through the above calculation.

[0090] In some embodiments, step S603, i.e., the step of obtaining the body shape grade of the occupant based on the product of the weight score and the first weight and the product of the height score and the second weight, includes: matching the product of the weight score and the first weight and the product of the height score and the second weight with a preset body shape grading standard to obtain the body shape grade of the occupant.

[0091] It is worth noting that the specific method of obtaining the body shape grade of the occupant by matching the product of the weight score and the first weight and the product of the height score and the second weight with the preset body shape grading standard can be to match with nine preset body shapes of tall and fat, tall and medium weight, tall and thin, medium height and fat, medium height and medium weight, medium height and thin, short and fat, short and medium weight, and short and thin, so as to match a specific body shape.

[0092] Step S50, according to the body size grade, determine the inflation time of the first airbag and the second airbag, select at least one from the plurality of third airbags and determine the inflation time, select at least one from the plurality of fourth airbags and determine the inflation time.

[0093] It is worth noting that the inflation time determines the inflation amount, and further determines the bulging height / support height of the first airbag, the second airbag, the third airbag, and the fourth airbag. Normally, the inflation time of the first airbag and the second airbag is equal. The third and fourth airbags are the same. The inflation time of the first airbag and the second airbag depends on the body type classification. The higher the body type, the longer the inflation time, that is, the greater the inflation amount. Inflating the third and fourth airbags can support / massage specific areas of the occupant's back. When the body type is higher, the third and fourth airbags that are farther away from the seat cushion can be selected for inflation. When the body type is fatter, the third and fourth airbags that are farther away from the seat cushion can also be selected for inflation. In addition, the third and fourth airbags can also be selected comprehensively based on the height and weight of the body type.

[0094] Step S60, controlling the valve body to inflate the first airbag, the second airbag, the selected third airbag, and the selected fourth airbag.

[0095] By selecting different third and fourth airbags according to the body size of the occupants, the valve body is controlled to inflate the first airbag, the second airbag, the selected third airbag and the selected fourth airbag, so that the first airbag, the second airbag, the selected third airbag and the selected fourth airbag are inflated, which can accurately support / massage occupants of different heights and weights, thereby improving the user experience.

[0096] It is worth noting that, in some embodiments, the plurality of third air bags include a left first air bag, a left second air bag and a left third air bag which are sequentially away from the seat cushion; the plurality of fourth air bags include a right first air bag, a right second air bag and a right third air bag which are sequentially away from the seat cushion; the step S60, i.e., the step of controlling the valve body to inflate the first air bag, the second air bag, the selected third air bag and the selected fourth air bag, includes: when the body type grade is tall and fat, controlling the left The second air bag, the left third air bag, the right second air bag and the right third air bag are controlled to be inflated and deflated; when the body type level is tall in height and medium in weight, the left third air bag and the right third air bag are controlled to be inflated and deflated; when the body type level is medium in height and medium in weight, the left second air bag and the right second air bag are controlled to be inflated and deflated; when the body type level is medium in height and fat in weight, the left first air bag, the left second air bag, the right first air bag and the right second air bag are controlled to be inflated and deflated; when the body type level is short in height but of any weight, the left first air bag and the right first air bag are controlled to be inflated and deflated.

[0097] It is worth noting that, in order to simplify the calculation procedure and the control of the third air bag and the fourth air bag, although the preset body type classification standards include nine body types, namely, tall and fat, tall and medium weight, tall and thin, medium height and fat, medium height and medium weight, medium height and thin weight, short and fat, short height and medium weight, and short height and thin weight, when there are three of them, namely, short and fat, short and medium weight, and short and thin weight, these three are identified as body types of short height but any weight, and at this time, the left air bag and the right air bag are controlled to be inflated and deflated; when the body type level is tall and thin weight or medium height and thin weight, it is identified as short height. However, the logic of controlling the third and fourth airbags is the same for body types of any weight, that is, when the body type is tall and thin or medium height and thin, the left and right airbags are controlled to be inflated and deflated; thus, the body types of the occupants are ultimately determined to be only five types, namely tall and fat, tall and medium weight, medium height and fat, medium height and medium weight, and short height but any weight. Accordingly, there are only five strategies for controlling the inflation of the third and fourth airbags, thereby greatly reducing calculation and control, and ensuring that a comfortable back support / massage experience is provided for occupants with different body types.

[0098] In the embodiment of the present application, the adaptive support method for a car seat includes: obtaining the back sensing data of the occupant acting on the pressure sensing pad; processing the back sensing data to obtain pressure data; estimating the body shape of the occupant according to the pressure data; matching the body shape estimation result of the occupant with the preset body shape classification standard to obtain the body shape grade of the occupant; determining the inflation time of the first air bag and the second air bag according to the body shape grade, selecting at least one from the plurality of third air bags and determining the inflation time, selecting at least one from the plurality of fourth air bags and determining the inflation time; controlling the valve body to inflate the first air bag, the second air bag, the selected third air bag and the selected fourth air bag. Due to the setting of the plurality of third air bags and the plurality of fourth air bags, by controlling different combinations of the third air bags and the fourth air bags to inflate and deflate, thereby acting on the occupant, the back of the occupant with different height sizes can be accurately massaged; by inflating and deflation of the combination of the third air bag and the fourth air bag, the back of the occupant with different body sizes can also be accurately massaged, and the user experience is good.

[0099] In addition, in an embodiment of the present application, before controlling the inflation and deflation of different third air bags and fourth air bags, the body shape of the occupant is estimated based on the back sensing data obtained after the occupant acts on the pressure sensing pad, and the body size grade of the occupant is further obtained. Then, based on the body size grade of the occupant, the valve body is controlled to inflate the first air bag, the second air bag, the selected third air bag, and the selected fourth air bag. This can more accurately match occupants with different body shapes (including height and weight) and provide the occupants with a good support / massage experience.
