Description

Technical Field

[0001] This invention relates to the field of automotive parts, and in particular to a height-adjustable air cushion for use in car seats. Background Technology

[0002] With the continuous increase in consumption in China's automotive supplies market, car seat air cushions have become a major consumer product for car owners. Choosing a comfortable and practical car air cushion according to the season is particularly important. Currently, the inner cavity of car seats is generally designed with a closed structure, and the surface of the seat cushion is mostly wrapped with cotton cloth, genuine leather, or artificial leather, which has poor breathability.

[0003] Chinese patent discloses a car seat cushion (authorization announcement number CN206367413U), including a seat cushion, a back cushion, and a connecting plate. The upper end of the seat cushion and the lower end of the back cushion are connected by a connecting zipper; the seat cushion and the back cushion are provided with an inner layer; the bottom of the seat cushion and the top of the back cushion are provided with inner layer zippers; the sides of the seat cushion and the back cushion are provided with interlayers; a support plate is provided in the interlayer, and the support plates on the same side are connected by a connecting plate. This utility model provides a car seat cushion, which consists of a back cushion and a seat cushion, connected by a zipper for easy disassembly and cleaning; the back cushion and the seat cushion have an inner layer, which can be filled with different filling materials according to seasonal needs; the back cushion and the seat cushion are precisely positioned by a connecting rod, making them less likely to shift forward during use.

[0004] However, in practical applications of this patented technology, when summer arrives, the parts of the human body that come into direct contact with the car seat cushion, such as the buttocks, legs, and back, will sweat and even feel stuffy due to the poor breathability of the car seat cushion, resulting in a very poor driving and riding experience. Sweat stains will also be left on the backrest and surface of the seat cushion, which will lead to an unpleasant smell in the car and make the seat increasingly unhygienic, which is not conducive to practical application and promotion. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of strong odor inside automobiles mentioned in the background art. This invention provides a liftable air cushion for automobile seats.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A height-adjustable air cushion for car seats includes a seat body, a fixed box fixedly connected to the top of the seat body, protective boxes fixedly connected to both ends of the top of the fixed box, a backrest cushion located on the top of the seat body and on one side of the seat cushion, three air cushion bodies located inside the top of the fixed box and the backrest cushion, a seat cushion placed between the two protective boxes on the top of the air cushion bodies, ventilation holes evenly spaced at the top of the seat cushion, a controller fixedly installed on the outside of the seat body, a cavity inside the fixed box, odor removal mechanisms located on both sides of the cavity inside the fixed box, a heat dissipation mechanism inside the cavity, and an adjustment mechanism on the outside of the air cushion bodies.

[0008] By adopting the above technical solution, when a user enters the car, they can sit on the seat cushion. The ventilation holes allow the seat cushion under the user's buttocks to have good breathability. The protective box reduces the possibility of the user slipping off the seat cushion, playing an important role in preventing falls.

[0009] Furthermore, the odor removal mechanism includes a fragrance tray inside a fixed box. The fixed box has an installation slot inside, and a pressure-absorbing box is fixedly installed inside the installation slot. A first connecting pipe is fixedly connected to the bottom of the pressure-absorbing box. A delivery pipe is provided on the side of the fragrance tray near the first connecting pipe, with one end of the delivery pipe extending into the interior of the first connecting pipe. The end of the first connecting pipe away from the pressure-absorbing box extends into the interior of a protective box. Multiple rows of U-shaped tubes are fixedly connected to the top of the pressure-absorbing box, with the ends of the multiple rows of U-shaped tubes away from the pressure-absorbing box extending into the interior of the protective box. A pressure-absorbing assembly is provided inside the fixed box and on one side of the pressure-absorbing box. A transmission assembly is provided inside the cavity. A control assembly is provided inside the fixed box. A sweat-absorbing assembly is provided inside the protective box.

[0010] By adopting the above technical solution and setting up multiple rows of U-shaped tubes, the distance that odors travel into the pressure chamber can be increased, thereby increasing the reaction time between the odors and the activated carbon adsorption block, thus improving the odor removal effect. Furthermore, through the pressure operation of the pressure chamber, the gas after removing the odors can be mixed with the fragrance gas, thereby increasing the diffusion volume of the fragrance gas and counteracting the odors in the car, thus further removing the odors in the car.

[0011] Furthermore, the pressure-drawing assembly includes a piston plate slidably connected inside the pressure-drawing box, a transmission rod rotatably connected inside the pressure-drawing box, a turntable fixedly connected to the top of the transmission rod, a connecting rod rotatably connected to the eccentric position at the top of the turntable, the piston plate rotatably connected to the end of the connecting rod away from the turntable, and the bottom of the transmission rod extending to the outside of the pressure-drawing box and rotatably connected to the inner wall of the mounting groove.

[0012] By adopting the above technical solution, the rotation of the turntable can pull the connecting rod to swing, thereby driving the piston plate to perform a suction operation in the pressure box.

[0013] Furthermore, the transmission assembly includes a servo motor fixedly mounted on the inner wall of the cavity. A fourth bevel gear is fixedly connected to the outer side of the output shaft of the servo motor. A fixed plate is fixedly connected to the inside of the cavity. A rotating rod is rotatably connected to the inside of the fixed plate. A third bevel gear is fixedly connected to one end of the rotating rod. A second bevel gear is fixedly connected to the end of the rotating rod away from the third bevel gear. A worm gear is rotatably connected between the inner walls of the cavity. A first bevel gear is fixedly connected to the outer side of the worm gear. The first bevel gear meshes with the second bevel gear. The third bevel gear meshes with the fourth bevel gear. The outer side of the output shaft of the servo motor and the transmission rod are both connected by a transmission belt.

[0014] By adopting the above technical solution, the rotation of the output shaft of the servo motor can drive the rotation of the transmission rod, thereby providing power to the pumping assembly. At the same time, it can drive the rotation of the fourth bevel gear, which in turn drives the rotation of the third bevel gear, which in turn drives the rotation of the rotating rod, thus transmitting power to the heat dissipation mechanism.

[0015] Furthermore, the control component includes a third one-way valve fixedly installed inside the through pipe, a second one-way valve fixedly installed inside the first connecting pipe, activated carbon adsorption blocks fixedly installed at equal intervals inside the multi-row U-shaped pipe, and a first one-way valve fixedly installed inside the multi-row U-shaped pipe at one end away from the protective box.

[0016] By adopting the above technical solution, through the combined action of the first one-way valve, the second one-way valve and the third one-way valve, the filtered odor gas and fragrance gas can be drawn into the vacuum chamber together. At the same time, during the process of the odor gas being drawn into the vacuum chamber, the odor gas is filtered, and the gas mixed with the odor gas is fully utilized to play an important role in heat dissipation on both sides of the user.

[0017] Furthermore, the sweat-absorbing component includes limiting grooves at both ends inside the protective box, with limiting blocks slidably connected inside each limiting groove. A pull-out plate is slidably connected inside each protective box. Two limiting blocks are fixedly connected to both sides of the pull-out plate. Spray nozzles are fixedly connected at equal intervals on the adjacent sides of the two protective boxes. Sweat-absorbing paper is adhered to the adjacent sides of the two pull-out plates. Bolts are installed inside each protective box, with the bottom of each bolt abutting against the corresponding pull-out plate. Air inlets are equidistantly opened on the outer side of the fixed box.

[0018] By adopting the above technical solution, when the suction box is in suction mode, it will collect the sweat produced by the user through the nozzle, and absorb the sweat through the action of the sweat-absorbing paper. Then, the sweat-absorbing paper can be easily replaced by pulling out the pull plate from the protective box. The pull plate can play an important limiting role through the cooperation of the limiting block and the limiting groove.

[0019] Furthermore, the heat dissipation mechanism includes a support plate fixedly connected to the interior of the cavity. A rotating shaft is equidistantly rotatably connected to one side of the support plate. A fan is fixedly connected to the outer side of each rotating shaft. A worm gear is fixedly connected to the end of each rotating shaft away from the support plate. The worm and the worm gear are meshed together. Two air outlets are opened at the top of the interior of the fixed box. Circular grooves are provided at both ends of the interior of the air cushion body. An air inlet is opened at the bottom of the interior of the seat cushion, which matches the circular grooves. An air supply pipe is fixedly connected to the interior of the fixed box. The end of the air supply pipe away from the fixed box extends into the interior of the backrest cushion.

[0020] By adopting the above technical solution, when it is necessary to dissipate heat from the seat cushion and backrest, the rotation of the output shaft of the servo motor can drive the rotation of the fourth bevel gear, which in turn drives the rotation of multiple rotating shafts, thereby driving the corresponding fans to rotate. This allows the cavity to be filled with cool air, which enters the air inlet of the seat cushion through the air outlet and then enters the interior of the seat cushion, thus dissipating heat from under the user's buttocks, reducing sweating in the car, reducing odor, and improving user comfort.

[0021] Furthermore, the adjustment mechanism includes an air pump fixedly installed on the inner wall of the cavity. The air pump has six output ends, each of which is fixedly connected to a corresponding air cushion body. A solenoid valve is fixedly installed inside the air pump output end and at the end closest to the air cushion body.

[0022] By adopting the above technical solution, when it is necessary to adjust the seat cushion and backrest cushion, the air pump can be started by the controller, and the corresponding solenoid valve can be opened to inflate the corresponding air cushion. With three adjustable levels, it can be adapted to drivers of different body shapes, thereby improving the driver's user experience and comfort.

[0023] In summary, the present invention has at least one of the following beneficial effects;

[0024] 1. This invention addresses the issue of unpleasant odors emanating from a car seat due to prolonged sitting and the enclosed space of a vehicle caused by perspiration. Fragrance gas is introduced into the fragrance chamber, and a servo motor is activated. A transmission belt drives the output shaft of the servo motor, rotating the transmission rods on both sides, thus activating the suction mechanism. When the suction chamber is in suction mode, the nozzle collects odors and sweat from both sides of the seat. Simultaneously, the fragrance gas enters the suction chamber through a first connecting pipe. As the odor enters the multi-row U-shaped tubes, it is filtered by multiple activated carbon adsorption blocks. The multi-row U-shaped tubes increase the distance the odor travels into the suction chamber, thus increasing the reaction time between the odor and the activated carbon adsorption blocks, thereby improving the odor removal effect. Furthermore, the suction chamber mixes the odor-removed gas with the fragrance gas, increasing the diffusion volume of the fragrance gas and further enhancing its effectiveness in eliminating odors in the car. The system uses a pump to further remove odors from the car. When the pressure chamber is extended, the mixed gas is sprayed out from the nozzle, effectively removing odors while also providing important heat dissipation. As the output shaft of the servo motor in the odor removal mechanism rotates, it drives the corresponding fan, filling the cavity with cool air. This cool air then enters the seat cushion and, through the air pipe, is delivered to the backrest cushion, cooling the user's back and buttocks, reducing sweating, further minimizing odors, and improving user comfort. When adjusting the seat and backrest cushions, the controller activates the air pump and opens the corresponding solenoid valve to inflate the airbags. Three adjustable settings cater to drivers of different body types, enhancing the driver's experience and comfort.

[0025] 2. In this invention, the rotation of the output shaft of the servo motor drives the rotation of the fourth bevel gear, which in turn drives the rotation of multiple rotating shafts, thereby driving the corresponding fans to rotate. This allows the cavity to be filled with cool air, which enters the air inlet of the seat cushion through the air outlet and then enters the interior of the seat cushion. This effectively dissipates heat from under the user's buttocks, reducing sweating in the car and further reducing odor. The odor removal mechanism and the heat dissipation mechanism can operate simultaneously, resulting in better heat dissipation.

[0026] 3. This invention controls the air pump to start via a controller and opens the corresponding solenoid valve. In the first setting, the first air cushion under the seat inflates, and the first air cushion behind the backrest inflates, suitable for larger drivers. In the second setting, the air cushion under the seat inflates the second air cushion after the first air cushion is fully inflated, and the second air cushion behind the backrest inflates after the first air cushion is fully inflated, suitable for drivers of medium build. In the third setting, the third air cushion under the seat inflates, and the third air cushion behind the backrest inflates, suitable for smaller drivers. These three settings allow for adjustment of the seat and backrest height, adapting to users of different body types and improving the driver's experience and comfort. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 —7. The present invention will be described in further detail.

[0037] This invention discloses a height-adjustable air cushion for use in car seats.

[0038] Reference Figure 1-2 A height-adjustable air cushion for car seats includes a seat body 1, a fixed box 5 fixedly connected to the top of the seat body 1, protective boxes 7 fixedly connected to both ends of the top of the fixed box 5, a backrest cushion 42 set on the top of the seat body 1 and on one side of the seat cushion 3, three air cushion bodies 2 set inside the top of the fixed box 5 and the backrest cushion 42, a seat cushion 3 placed on the top of the air cushion body 2 and between the two protective boxes 7, ventilation holes 4 are equidistantly opened at the top of the inside of the seat cushion 3, a controller is fixedly installed on the outside of the seat body 1, a cavity 40 is opened inside the fixed box 5, an odor removal mechanism is set inside the fixed box 5 and on both sides of the cavity 40, a heat dissipation mechanism is set inside the cavity 40, and an adjustment mechanism is set on the outside of the air cushion body 2.

[0039] Once inside the car, the user can sit on the seat cushion 3. The ventilation holes 4 allow for good breathability under the user's buttocks. The protective box 7 reduces the possibility of the user slipping off the seat cushion 3, playing an important role in preventing falls.

[0040] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the odor removal mechanism includes a fragrance tank 6 inside a fixed box 5. A mounting slot is provided inside the fixed box 5, and a pressure box 30 is fixedly installed inside the mounting slot. A first connecting pipe 37 is fixedly connected to the bottom of the pressure box 30. A delivery pipe is provided on the side of the fragrance tank 6 near the first connecting pipe 37. One end of the delivery pipe extends into the interior of the first connecting pipe 37, and the end of the first connecting pipe 37 away from the pressure box 30 extends into the interior of a protective box 7. Multiple rows of U-shaped tubes 34 are fixedly connected to the top of the pressure box 30. The ends of the multiple rows of U-shaped tubes 34 away from the pressure box 30 extend into the interior of the protective box 7. A pressure-removing component is provided inside the fixed box 5 and on one side of the pressure box 30. A transmission component is provided inside the cavity 40. A control component is provided inside the fixed box 5. A sweat-absorbing component is provided inside the protective box 7.

[0041] The pressure-drawing assembly includes a piston plate 33 slidably connected inside the pressure-drawing box 30, a transmission rod 43 rotatably connected inside the pressure-drawing box 30, a turntable 31 fixedly connected to the top of the transmission rod 43, a connecting rod 32 rotatably connected to the eccentric position at the top of the turntable 31, the piston plate 33 and the end of the connecting rod 32 away from the turntable 31 are rotatably connected, and the bottom of the transmission rod 43 extends to the outside of the pressure-drawing box 30 and is rotatably connected to the inner wall of the mounting groove.

[0042] In addition, the transmission assembly includes a servo motor 11 fixedly installed on the inner wall of the cavity 40. A fourth bevel gear 26 is fixedly connected to the outer side of the output shaft of the servo motor 11. A fixed plate 24 is fixedly connected inside the cavity 40. A rotating rod 23 is rotatably connected inside the fixed plate 24. A third bevel gear 25 is fixedly connected to one end of the rotating rod 23. A second bevel gear 20 is fixedly connected to the end of the rotating rod 23 away from the third bevel gear 25. A worm gear 12 is rotatably connected between the inner walls of the cavity 40. A first bevel gear 19 is fixedly connected to the outer side of the worm gear 12. The first bevel gear 19 meshes with the second bevel gear 20. The third bevel gear 25 meshes with the fourth bevel gear 26. The outer side of the output shaft of the servo motor 11 and the transmission rod 43 are both connected by a transmission belt.

[0043] Furthermore, the control components include a third one-way valve 39 fixedly installed inside the through pipe, a second one-way valve 38 fixedly installed inside the first connecting pipe 37, activated carbon adsorption blocks 35 fixedly installed at equal intervals inside the multi-row U-shaped pipes 34, and a first one-way valve 36 fixedly installed inside the multi-row U-shaped pipes 34 at one end away from the protective box 7.

[0044] In addition, the sweat-absorbing component includes limiting grooves 29 at both ends inside the protective box 7. Limiting blocks 28 are slidably connected inside the limiting grooves 29. Pull-out plates 8 are slidably connected inside the protective box 7. The two limiting blocks 28 are fixedly connected to the two sides of the pull-out plates 8 respectively. Spray nozzles 10 are fixedly connected at equal intervals on the side of the two protective boxes 7 that are close to each other. Sweat-absorbing paper 9 is glued to the side of the two pull-out plates 8 that are close to each other. Bolts are provided inside the protective box 7. The bottom of the bolts abuts against the corresponding pull-out plates 8. Air inlets are opened at equal intervals on the outside of the fixed box 5.

[0045] When the user sits on the cushion 3, fragrance gas can be added to the fragrance tank 6. Then, the servo motor 11 is started, and through the transmission belt, the rotation of the output shaft of the servo motor 11 drives the rotation of the transmission rods 43 on both sides, which in turn drives the rotation of the turntable 31. At the same time, the connecting rod 32 is pulled to swing, which in turn drives the piston plate 33 to slide back and forth in the corresponding suction box 30, thereby realizing the suction operation of the suction box 30. When the piston plate 33 moves to the position of Figure 5 When the pressure chamber 30 is on the right side, the nozzle 10 collects the odor and sweat from both sides of the seat cushion 3. Simultaneously, the fragrance gas enters the pressure chamber 30 through the first connecting pipe 37. The sweat is drawn into the protective box 7 by the suction of the nozzle 10 and absorbed by the absorbent paper 9. The odor continues to enter the multi-row U-shaped tube 34 and is filtered by multiple activated carbon adsorption blocks 35 before entering the pressure chamber 30. The second one-way valve 38 prevents odor from entering the first connecting pipe 37 due to the suction of the pressure chamber 30. The pressure chamber 30 mixes the fragrance gas with the filtered odor gas. When the piston plate 33 moves to... Figure 5 When the pressure box 30 is moved to the left, the mixed gas inside the pressure box 30 will be pushed out from the first connecting pipe 37. The first one-way valve 36 prevents the mixed gas from entering the multi-row U-shaped pipe 34, while the third one-way valve 39 prevents the mixed gas in the first connecting pipe 37 from flowing back into the fragrance tank 6. Thus, the odor-removing mixed gas can be sprayed out again through the nozzle 10 to both sides of the user, thereby achieving the function of removing odors and heat dissipation at the same time.

[0046] like Figure 2 , Figure 3 and Figure 4As shown, the heat dissipation mechanism includes a support plate 22 fixedly connected inside the cavity 40. A rotating shaft 21 is equidistantly rotatably connected to one side of the support plate 22. A fan 18 is fixedly connected to the outer side of the rotating shaft 21. A worm gear 13 is fixedly connected to the end of the rotating shaft 21 away from the support plate 22. The worm 12 is meshed with the worm gear 13. Two air outlets 17 are opened at the top of the fixed box 5. Circular grooves 15 are provided at both ends of the air cushion body 2. An air inlet 16 that matches the circular groove 15 is opened at the bottom of the seat cushion 3. An air supply pipe 27 is fixedly connected inside the fixed box 5. The end of the air supply pipe 27 away from the fixed box 5 extends into the interior of the backrest cushion 42.

[0047] Furthermore, the adjustment mechanism includes an air pump 14 fixedly installed on the inner wall of the cavity 40. The air pump 14 has six output ends, which are respectively fixedly connected to the corresponding air cushion body 2. Solenoid valves 41 are fixedly installed inside the output end of the air pump 14 and at the end closest to the air cushion body 2.

[0048] When it is necessary to dissipate heat from the seat cushion 3 and backrest cushion 42, the rotation of the output shaft of the servo motor 11 can drive the rotation of the fourth bevel gear 26, which in turn drives the rotation of the third bevel gear 25, and simultaneously drives the rotation of the rotating rod 23, which in turn drives the rotation of the second bevel gear 20, the rotation of the first bevel gear 19, and the rotation of the worm gear 12. Since the worm gear 12 and the worm wheel 13 are meshed, they can drive the rotation of multiple rotating shafts 21, which in turn drives the corresponding fan 18 to rotate. This allows the cavity 40 to be filled with cool air, which enters the air inlet 16 inside the seat cushion 3 through the air outlet 17, and then enters the interior of the seat cushion 3. This can dissipate heat from under the user's buttocks, reduce sweating in the car, reduce odor, and improve user comfort.

[0049] Both the air cushion under the seat cushion 3 and the air cushion behind the backrest cushion 42 are divided into three layers, corresponding to three adjustment levels. When it is necessary to adjust the seat cushion 3 and the backrest cushion 42, the air pump 14 can be started by controlling the controller to open the corresponding solenoid valve 41. When the first adjustment is started, the first layer of air cushion under the seat cushion 3 and the first layer of air cushion behind the backrest cushion 42 are inflated, which can accommodate drivers of larger size. When the second adjustment is started, the air cushion under the seat cushion 3 inflates the second layer of air cushion after the first layer of air cushion is inflated, and at the same time, the second layer of air cushion behind the backrest cushion 42 is also inflated after the first layer of air cushion is inflated. At this time, the seat is suitable for drivers of medium size. When the third adjustment is started, the third layer of air cushion 3 begins to inflate on the basis of the second adjustment, and at the same time, the third layer of air cushion behind the backrest cushion 42 also begins to inflate. At this time, it is suitable for drivers of smaller size. Through the three adjustment levels, it can be adapted to drivers of different body sizes, thereby improving the driver's user experience and comfort.

[0050] Working principle: When a user sits on the seat cushion 3 for a long time, and the car space is relatively enclosed, odors may be emitted due to the user's sweat. Fragrance gas can be added to the fragrance tank 6, the cap tightened, and the servo motor 11 started. Through the transmission belt, the rotation of the output shaft of the servo motor 11 drives the rotation of the transmission rods 43 on both sides, which in turn drives the rotation of the turntable 31. Simultaneously, it pulls the connecting rod 32 to swing, causing the piston plate 33 to slide back and forth within the corresponding suction box 30, thus realizing the suction operation of the suction box 30. When the piston plate 33 moves to the position... Figure 5 When the pressure chamber 30 is on the right side, the nozzle 10 collects the odor and sweat from both sides of the seat cushion 3. Simultaneously, the fragrance gas enters the pressure chamber 30 through the first connecting pipe 37, while the sweat is drawn into the protective box 7 by the suction of the nozzle 10 and absorbed by the absorbent paper 9. The odor continues to enter the multi-row U-shaped tube 34 and is filtered by multiple activated carbon adsorption blocks 35 before entering the pressure chamber 30. The second one-way valve 38 prevents odor from entering the first connecting pipe 37 due to the suction of the pressure chamber 30. The pressure chamber 30 then mixes the fragrance gas with the filtered odor gas. When the piston plate 33 moves to... Figure 5When the pressure chamber 30 is moved to the left, the mixed gas inside the pressure chamber 30 will be pushed out from the first connecting pipe 37. The first one-way valve 36 prevents the mixed gas from entering the multi-row U-shaped pipe 34, while the third one-way valve 39 prevents the mixed gas in the first connecting pipe 37 from flowing back into the fragrance tank 6. Thus, the odor-removing mixed gas can be sprayed again through the nozzle 10 to both sides of the user, thereby achieving odor removal and playing an important role in heat dissipation. When the output shaft of the servo motor 11 rotates, it will drive the fourth bevel gear 26 to... The rotation of the shaft drives the rotation of the third bevel gear 25, which in turn drives the rotation of the rotating rod 23, which in turn drives the rotation of the second bevel gear 20, the first bevel gear 19, and the worm gear 12. Since the worm gear 12 and the worm wheel 13 are meshed, this drives the rotation of multiple rotating shafts 21, which in turn drives the corresponding fans 18 to rotate. This fills the cavity 40 with cold air, which enters the air inlet 16 inside the seat cushion 3 through the air outlet 17, and then enters the interior of the seat cushion 3. Simultaneously, the cold air is transmitted to the air supply pipe 27. The backrest cushion 42 provides ventilation for the user's back and buttocks, reducing sweating inside the car and thus minimizing odor, while also improving user comfort. When adjustment of the seat cushion 3 and backrest cushion 42 is needed, the controller activates the air pump 14 and opens the corresponding solenoid valve 41. In the first setting, the first layer of air cushion 2 under the seat cushion 3 and the first layer of air cushion 42 behind the backrest cushion 42 inflate, accommodating larger drivers. In the second setting, the air cushion 41 under the seat cushion 3 inflates... After the first air cushion body 2 is fully inflated, the second air cushion body 2 is inflated. At the same time, the second air cushion body 2 behind the backrest cushion 42 is also inflated after the first air cushion body 2 is fully inflated. At this time, the seat is suitable for drivers of medium size. When the third gear is activated, the third air cushion body 2 of the seat cushion 3 begins to inflate on the basis of the second gear, and the third air cushion body 2 behind the backrest cushion 42 also begins to inflate. At this time, it is suitable for drivers of smaller size. Through the three gear adjustments, it can be adapted to drivers of different body sizes, thereby improving the driver's user experience and comfort.
