[0010] In one embodiment, the elastic layer is provided with protrusions extending toward the inflatable pad, the protrusions being adapted to engage with the recesses.

[0011] In one embodiment, a gas channel is formed between the filler and the air cushion body. The gas channel communicates with the outside and is used to inflate the air cushion, thereby inflating the filler, or to deflate the air cushion, thereby inflating the filler.

[0012] In one embodiment, the gas channel includes a first gas channel located between the circumferential side of the filler and the air cushion body.

[0013] In one embodiment, the filler has a first surface facing the main body portion of the first sheet and a second surface facing the main body portion of the second sheet; the gas passage further includes a second gas passage located between the first surface and the main body portion of the first sheet; and / or a third gas passage located between the second surface and the main body portion of the second sheet.

[0014] In one embodiment, the interior of the filler is provided with an internal air passage that communicates with a gas channel.

[0015] In one embodiment, the inflatable pad is combined with an elastic layer in such a way that the inflator is compressed; the inflator recovers when inflated.

[0016] In one embodiment, the inflatable pad is disposed on the second surface of the elastic layer; the pad also includes a clamping plate, the inflatable pad being pressed between the clamping plate and the second surface of the elastic layer.

[0024] The beneficial effects of this application are as follows: When using the vehicle seat of this application, the occupant can inflate the padding as needed, increasing the volume of the padding and the air cushion. The elastic layer is compressed by the air cushion, reducing its thickness and increasing its hardness, making the occupant feel a higher firmness in the cushion. The occupant can also deflate the padding as needed, reducing the volume of the padding and the air cushion. Correspondingly, the elastic layer is compressed less, regains its shape, becomes more flexible, and decreases in hardness, making the occupant feel a lower firmness in the cushion. Thus, the occupant can adjust the firmness of the seat cushion according to their own needs, which helps to improve the comfort of the seat. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, the passenger compartment of vehicle 1 is provided with a seat 11 (hereinafter referred to as seat 11) for passengers to sit on.

[0044] like Figure 2 As shown, the seat 11 includes a backrest 111 and a seat 112. (See reference...) Figure 3 and Figure 4 The seat 112 mainly includes a support frame 2 and an elastic cushion 3 mounted on the support frame 2 to provide a comfortable riding experience for the occupant. The backrest 111 has a cushion similar to the cushion 3 of the seat 112. For simplicity, the technical solution of this application will be described below using the cushion 3 of the seat 112 as an example.

[0045] The support frame 2 has good rigidity to support the weight of the cushion 3 and the weight of the occupant sitting on the seat 11. In one embodiment, the support frame may be made of steel or other suitable rigid material. Support frames are well known to those skilled in the art and will not be described in detail here.

[0046] The cushion 3 includes an elastic layer 31 and an inflatable cushion 32 laminated and combined with the elastic layer 31. The elastic layer 31 has a first surface 311 facing the occupant and a second surface 312 facing away from the occupant. The inflatable cushion 32 is positioned away from the first surface 311 of the elastic layer 31. In addition, the cushion 3 also includes a face cover 301 disposed on one side of the first surface 311 of the elastic layer 31. The face cover 301 can be used as the outer surface of the seat portion 111.

[0047] The elastic layer 31 provides elasticity to the pad 3. The elastic layer 31 can be deformed by compression when subjected to compressive force and can recover to a corresponding extent after the compressive force is reduced or removed. In one embodiment, the elastic layer is made of foam.

[0048] In some cases, such as Figure 3 As shown, the elastic layer 31 also includes a first elastic sublayer 31a and a second elastic sublayer 31b stacked along the thickness direction D1 of the cushion 3. The first elastic sublayer 31a faces the occupant and has a first surface 311 of the elastic layer 31, while the second elastic sublayer 31b faces away from the occupant and has a second surface 312 of the elastic layer 31. Typically, the elasticity of the first elastic sublayer 31a is greater than that of the second elastic sublayer 31b. Thus, the second elastic sublayer 31b provides good support for the first elastic sublayer 31a. The first elastic sublayer 31a gives the cushion 3 good flexibility. Both the first elastic sublayer 31a and the second elastic sublayer 31b can be made of suitable foam, which will not be described in detail here. In other cases, the elastic layer can also be constructed to have three or more sublayers, which will not be described in detail here. For simplicity, the following description uses the example of the elastic layer 31 including the first elastic sublayer 31a and the second elastic sublayer 31b to illustrate the technical solution of this application.

[0049] like Figure 3 As shown, the inflatable cushion 32 is disposed on the second surface 312 of the second elastic sublayer 31b (or elastic layer 31). Thus, when the occupant sits on the seat 11, the inflatable cushion 32 is located on the side of the elastic layer 31 away from the occupant (i.e., the elastic layer 31 separates the occupant from the inflatable cushion 32). Figure 5b An inflatable cushion is shown schematically. Figure 5c Another inflatable mattress is shown schematically. The main differences between the two inflatable mattresses are their shapes and the different positions of the first and second connecting structures. The first and second connecting structures will be described below.

[0050] Reference Figure 5b , Figure 5c and Figure 6 The inflatable cushion 32 includes an air cushion body 33 and a filler 34. The interior of the air cushion body 33 is a receiving space, and the filler 34 is disposed within the receiving space.

[0051] The air cushion body 33 includes a first sheet 331 and a second sheet 332 opposite to each other. The edges of the first sheet 331 and the second sheet 332 are joined to form a pouch shape, thus defining the aforementioned receiving space together. In one embodiment, both the first sheet and the second sheet are made of TPU (thermoplastic polyurethane), which gives the air cushion body good elasticity and airtightness, allowing it to expand or contract with changes in the volume of the filler. Of course, depending on the specific circumstances, the first sheet and the second sheet can also be made of other suitable materials, such as an elastic rubber membrane.

[0052] The shape of the filler 34 matches the shape of the receiving space. For example, the filler 34 has a first surface 341 facing the main body of the first sheet 331, a second surface 342 facing the main body of the second sheet 332, and a circumferential side surface 343 connecting the first surface 341 and the second surface 342. In one embodiment, the filler 34 has a plurality of pores inside (in other words, the filler is a porous structure). For example, the filler can be made of foam. In this way, the filler 34 can be inflated to increase its volume (e.g., the thickness of the filler increases) or deflated to shrink its volume (e.g., the thickness of the filler decreases). Of course, depending on the actual situation, the filler can also be made of other suitable materials, such as three-dimensional mesh fabric, etc. Three-dimensional mesh fabric is well known to those skilled in the art and will not be described in detail here.

[0053] Reference Figure 8 and Figure 9 When the air cushion 32 is inflated, the air pressure within the containment space of the air cushion body 33 increases, causing gas to gradually fill the pores of the filler 34. This results in a gradual increase in the volume and thickness of the filler 34, and consequently, a gradual increase in the thickness of the air cushion 32. The elastic layer 31 is compressed by the air cushion 32, causing its thickness to decrease (e.g., ...). Figure 9 As shown, the thickness of the second elastic sublayer 31b decreases and its hardness increases. For example, in the case of an elastic layer made of foam, the pores within the foam are compressed and become smaller or even closed. As a result, the occupants experience an increase in the hardness of the cushion 3.

[0054] When the air cushion 32 is deflated, the gas in the pores of the filler 34 is also expelled, causing the filler 34 to gradually decrease in volume and thickness, and the thickness of the air cushion 32 to also decrease. This reduces the pressure of the air cushion 32 on the elastic layer 31, allowing the elastic layer 31 to regain its shape, increase in thickness, and decrease in hardness (for example, in the case of an elastic layer made of foam, the pores within the foam open at least partially). Consequently, the occupant experiences a decrease in the firmness of the cushion 3. This allows the occupant to adjust the firmness of the seat 112 according to their needs, contributing to improved seat comfort. It should be understood that, in this application, when expelling the gas from the containment space of the air cushion body 33, only a portion of the gas in the containment space may be expelled, or almost all of the gas may be expelled, depending on the specific circumstances.

[0055] In some existing pads, the inflatable pad is positioned at the first surface of the elastic layer (i.e., the inflatable pad is positioned between the occupant and the elastic layer). In other words, the elastic layer does not separate the inflatable pad from the occupant. This can result in different pressures on different parts of the inflatable pad, causing some areas of the padding to be inflated more and some areas to be inflated less, leading to uneven padding firmness perceived by the occupant. For example, in a prior art pad, when there is only one inflatable pad supporting the hips and legs, the hips exert greater pressure on the inflatable pad, while the legs exert less pressure. Thus, the portion of the inflatable pad corresponding to the hips is compressed more (the corresponding portion of the padding is less inflated), while the portion corresponding to the legs is compressed less (the corresponding portion of the padding is more inflated). Consequently, the portion of the pad corresponding to the hips is firmer, while the portion corresponding to the legs is less firm. Compared to prior art pads, in the pad of this application, the elastic layer 31 separates the occupant from the inflatable pad 32 (as described above). According to this structure, the elastic layer 31 distributes the pressure exerted by the occupant on the pad 3 relatively evenly onto the inflatable pad 32 (i.e., the pressure on each part of the inflatable pad 32 is approximately equal). This makes the force on different areas of the inflatable pad 32 approximately equal, and the amount of air in each area of ​​the filling 34 is also approximately equal, thus the occupant experiences a better uniformity of the hardness of the pad 3.

[0056] For example Figure 4 As shown, the main body portion 331a of the first piece 331 (i.e., the portion away from the edge of the first piece) and the main body portion 332a of the second piece 332 (i.e., the portion away from the edge of the second piece) are connected by multiple connecting structures 322. When gas is filled into the receiving space of the air cushion body 33, these connecting structures 322 prevent the air cushion body 33 from over-expanding and deforming, avoiding adverse effects on the occupant's sitting posture and preventing an unstable sitting feeling for the occupant.

[0057] These connecting mechanisms 322 also extend through the insulator 34 to restrain it. This prevents the insulator 34 from moving within the air cushion body 33 and adversely affecting the occupant's riding comfort.

[0058] As mentioned earlier, the elastic layer 31 separates the occupant from the inflatable cushion 32. This helps prevent the occupant from feeling any foreign object sensation from the inflatable cushion 32, thus contributing to improved seat comfort. Additionally, refer to... Figure 8 and Figure 9 When the air cushion 32 is inflated, increasing the thickness of the filler 34, the elastic layer 31 is compressed, reducing its thickness. In other words, the elastic layer 31 absorbs most of the increase in the thickness of the filler 34. Therefore, the occupant's height does not increase or increases very little, which also helps improve the occupant's riding comfort.

[0059] For example Figure 5b and Figure 5c As shown, the seat 11 also includes an air pipe 113 and an air pump (not shown) communicating with the accommodating space to facilitate the inflation of the air cushion 32. If the seat has an inflatable massage system (not shown), the air cushion and the inflatable massage system can share the air pump. Additionally, an air valve (not shown) can be installed on the air pipe to control the inflation and / or deflation speed of the air cushion as needed, preventing occupants from experiencing an unstable seating experience. The inflation and deflation speeds of the air cushion can be determined based on actual conditions and are not limited here.

[0060] Reference Figure 5b , Figure 5c and Figure 6 The connecting structure 322 includes a plurality of first connecting structures 322a. Each first connecting structure 322a defines a first vent 321 extending through the inflatable pad 32. For example, as Figure 7a As shown, the first connecting structure 322a includes a first hole 333 formed on the first sheet 331, a second hole 334 formed on the second sheet 332, and an annular connecting wall 335. The connecting wall 335 connects between the edges of the first hole 333 and the second hole 334 along the thickness direction D2 of the air cushion 32. In other words, the connecting wall 335 connects between the first sheet 331 and the second sheet 332, thereby constraining the expansion of the air cushion body 33. It should be understood that the connecting wall 335 extends through the filler 34 to constrain the filler 34.

[0061] The connecting wall 335 forms the first ventilation hole 321 that penetrates the inflatable cushion 32. Also, Figure 4 As shown, a second ventilation hole 313 is provided on the elastic layer 31, and the second ventilation hole 313 is connected to the first ventilation hole 321. Additionally, micropores (not shown in the figure) are provided on the face mask 301, and the micropores are connected to the second ventilation hole 313. This allows airflow to pass through the first ventilation hole 321, the second ventilation hole 313, and the micropores on the face mask 301, providing ventilation to the occupant sitting in the seat (i.e., the seat has a ventilation effect), further improving the comfort of the seat.

[0062] For example Figure 5b , Figure 5c and Figure 6 As shown, the connection structure 322 also includes a plurality of second connection structures 322b. For example... Figure 7bAs shown, each second connecting structure 322b includes a first connecting portion 336 formed on the main body portion 331a of the first sheet 331 and a second connecting portion 337 formed on the main body portion 332a of the second sheet 332. Both the first connecting portion 336 and the second connecting portion 337 are configured as recesses extending toward the receiving space. The bottoms 338 of the two recesses (i.e., the first connecting portion 336 and the second connecting portion 337) are connected to each other. Thus, these second connecting structures 322b do not define a first vent through the inflatable pad 32. In one embodiment, these second connecting structures 322b are implemented as a weld point connecting the first sheet 331 and the second sheet 332. The second connecting structures 322b may also pass through the filler 34 to provide restraint to the filler 34. It should be understood that the distances by which the first connecting portion and the second connecting portion extend toward the receiving space may be the same or different. In one embodiment, only the first connecting portion is configured as a recess extending toward the receiving space, and the second connecting portion is substantially flush with the rest of the main body portion of the second sheet. Of course, the second connecting part can also be constructed as a recess, and the first connecting part is basically flush with the rest of the main body of the first piece.

[0063] The second connecting structure 322b also serves to constrain the expansion of the air cushion body 33. Depending on the actual situation, the second connecting structure and the first connecting structure can be mixed together and randomly distributed, or the first connecting structure and the connecting structure can be set according to an appropriate pattern, which will not be elaborated here.

[0064] like Figure 5a As shown, the elastic layer 31 is provided with a plurality of protrusions 315 extending toward the inflatable cushion 32. These protrusions 315 respectively engage with recesses for forming the second connection structure. The protrusions 315 substantially fill the recesses, which helps to prevent the occupant from feeling a partial collapse of the cushion 3, further improving the comfort of the seat.

[0065] For example Figure 6 As shown, a gas channel 305 is formed between the inflator 34 and the air cushion body 33. The gas channel 305 is connected to an external inflation device (e.g., air tube 113) and is used to inflate the air cushion 32 to inflate the inflator 34; it is also used to deflate the air cushion 32 to deflate the inflator 34.

[0066] like Figure 7a As shown, the gas channel 305 includes a first gas channel 324 located between the circumferential side 343 of the filler 34 and the air cushion body 33. The first gas channel 324 is connected to an external inflation device (e.g., air tube 113), which allows for convenient inflation or deflation of the air cushion 32.

[0067] Viewed as a whole, the first gas channel 324 surrounds the filling body 34 of the air pad 32. After the air pad 32 is inflated, the parts of the first piece 331 and the second piece 332, except for the connecting structure 322, separate from the filling body 34. In this way, the gas surrounds the filling body 34, facilitating the smooth entry of gas into the interior of the filling body 34 and thus increasing the hardness of the pad 3. When the air pad 32 is deflated, the gas inside the filling body 34 is correspondingly and smoothly expelled, thus reducing the hardness of the pad 3.

[0068] In one embodiment, a plurality of supports (not shown) are also provided in the first gas channel. The supports keep the first gas channel unobstructed at all times (even when the pad 3 is compressed) so that the inflatable pad can inflate and deflate smoothly. In addition, the filler 34 is constrained by the connecting structure 322 (as described above), which prevents the filler 34 from shifting within the receiving space and causing the first gas channel 324 to close.

[0069] As shown in Figure 7, the circumferential side surface 343 of the filler 34 is spaced apart from the air cushion body 33 to form the first gas channel 324 described above between the filler 34 and the air cushion body 33. In other embodiments, a groove (not shown) is provided on the circumferential side surface of the filler, and the groove, together with the air cushion body, defines the first gas channel described above.

[0070] In one embodiment, the filling body 34 has an internal air passage (not shown in the figure) communicating with the first gas channel 324. The internal air passage makes the inflation and deflation of the filling body 34 smoother. As a result, when the air pad 32 is inflated, the hardness of the pad 3 can be increased more smoothly; when the air pad 32 is deflated, the hardness of the pad 3 can be decreased more smoothly.

[0071] In one embodiment, the first surface 341 of the filler 34 and the main body 311a of the first sheet 331 are fitted together, and the second surface 342 of the filler 34 and the main body 322a of the second sheet 332 are fitted together. In this case, the gas channel 305 further includes a second gas channel (not shown in the figure) located between the first surface 341 of the filler 34 and the main body 311a of the first sheet 331; and / or a third gas channel (not shown in the figure) located between the second surface 342 of the filler 34 and the main body 322a of the second sheet 332. The second and third gas channels can be directly connected to an external inflation device or to the first gas channel. In addition, the second and third gas channels are also connected to the internal air passages inside the filler 34. In this way, the inflation and deflation of the filler 34 are smoother.

[0072] In one embodiment, similar to the structure of the first gas channel, a groove is formed on the first surface of the filler to form a second gas channel, and / or at least a portion of the main body of the first sheet is spaced apart from the first surface of the filler to form a second gas channel. The same applies to the third gas channel. Further details are omitted here.

[0073] In one embodiment, the inflatable pad 32 is combined with the elastic layer 31 in such a compressed manner as the filler 34. For example, see reference... Figure 3 and Figure 4 The cushion 3 also includes a clamping plate 302. The clamping plate 302 is disposed on one side of the second surface 312 of the elastic layer 31, and the inflatable cushion 32 is pressed between the clamping plate 302 and the second surface 312 of the elastic layer 31. When the inflatable cushion 32 is inflated, the filler 34 is gradually inflated, and the shape of the filler 34 gradually recovers and its thickness gradually increases. This helps to avoid the formation of a gas layer between the filler 34 and the first sheet 331 of the cushion body 33, and / or avoids the formation of a gas layer between the filler 34 and the second sheet 332 of the cushion body 33, thereby helping to avoid an unstable sitting experience for the occupant.

[0074] For example Figure 4 As shown, a groove 314 is provided on the second surface 312 of the elastic layer 31. The inflatable pad 32 is installed in the groove 314. When assembling the pad 3, the inflatable pad 32 is pre-positioned in the groove 314 and then pressed and fixed onto the elastic layer 31 by the clamping plate 302. This prevents the inflatable pad 32 from shifting and facilitates the assembly of the pad 3.

[0075] In one embodiment, the pressure plate 302 is configured as a porous structure, defining a plurality of third ventilation holes (not shown). These third ventilation holes communicate with the first ventilation hole 321. When ventilating the seat, the airflow passes through the plurality of third ventilation holes on the pressure plate 302 and is dispersed and softened by these third ventilation holes. The airflow then flows through the first ventilation hole 321 on the inflatable cushion 32, the second ventilation hole 313 on the elastic layer 31, and the micropores on the mask 301 to provide a gentle breeze to the occupant, which further improves the comfort of the seat.

[0076] In one embodiment, the inflatable cushion may also be disposed inside the elastic layer. For example, as... Figure 10 As shown, the inflatable cushion 32 is disposed between the first elastic sublayer 31a and the second elastic sublayer 31b. As mentioned above, the first elastic sublayer 31a faces the occupant, and the elasticity of the first elastic sublayer 31a is greater than that of the second elastic sublayer 31b. Thus, when the inflatable cushion 32 is inflated, the filler 34 is inflated and its thickness increases, causing the first elastic sublayer 31a to be significantly compressed and hardened (e.g., Figure 11As shown in the diagram, the occupant can then feel an increase in the firmness of the pad 3. When the air pad 32 is deflated, the filler 34 also deflates and its thickness decreases, so that the first elastic sublayer 31a is no longer compressed and returns to a state of good elasticity, thus the occupant can feel a significant decrease in the firmness of the pad 3. In other words, by inflating and deflating the air pad 32 (or the filler 34), the occupant can easily change the firmness of the pad 3.

[0077] Also refer to Figure 10 and Figure 11 When the air cushion 32 is inflated, the second elastic sublayer 31b is also compressed by the air cushion 32, reducing its thickness. In this way, the first elastic sublayer 31a and the second elastic sublayer 31b absorb most of the deformation of the filler 34 (or the air cushion 32). Therefore, the occupant's height does not increase or barely increases, which also helps to improve the occupant's riding comfort.

[0078] For example Figure 4 As shown, a pressure sensor assembly 303 is disposed on one side of the first surface 311 of the elastic layer 31. For example, the pressure sensor assembly 303 is generally sheet-like, disposed on the first surface 311 of the elastic layer 31, and covered by the face shield 301. The pressure sensor assembly 303 can be used to monitor the pressure applied by the occupant to the seat cushion 3, and thereby adaptively adjust the firmness of the cushion 3, which is easily implemented by those skilled in the art and will not be described in detail here. It should be understood that a fourth ventilation hole 304 may also be provided on the sheet-like pressure sensor assembly to avoid adversely affecting the ventilation effect of the seat.

[0079] In one embodiment, there can be multiple air cushions 32. Each air cushion 32 can be independently inflated and deflated to accommodate the personalized needs of different body parts of the occupant for seat cushion firmness, which also helps to improve seat comfort. Of course, depending on the actual situation, there can also be only one air cushion.

[0080] like Figure 12a As shown, there is one inflatable cushion 32, and this inflatable cushion 32 is used to support the occupant's two legs and entire buttocks. Figure 12b As shown, there are two inflatable cushions 32, arranged side-by-side along the width W of the seat. Each inflatable cushion 32 supports a corresponding leg and a corresponding buttock area. This allows the occupant to individually adjust the inflation level of each cushion 32, thereby changing the firmness of the corresponding area of ​​the cushion. For example, this is suitable for situations where the pressure applied to the cushion along the width of the seat is uneven when the occupant leans to one side. Figure 12cAs shown, there are two inflatable cushions 32, arranged side-by-side along the fore-and-aft direction L of the seat. The rear inflatable cushion 32 supports the entire buttocks, while the front inflatable cushion 32 supports the legs. Figure 12b Similarly, occupants can individually adjust the inflation level of each air cushion 32 according to actual needs, thereby changing the firmness of the corresponding area of ​​the cushion. For example, a larger inflation level in the rear air cushion 32 increases the firmness of the rear area of ​​the cushion to meet the need for higher support for the buttocks; a smaller inflation level in the rear air cushion 32 decreases the firmness of the front area of ​​the cushion to meet the need for lower support for the legs. Figure 12d As shown, there are four inflatable cushions 32. Two inflatable cushions 32 are located at the rear of the cushion and arranged side-by-side along the width of the seat to support the two buttocks respectively. The other two inflatable cushions 32 are located at the front of the cushion and arranged side-by-side along the width of the seat to support the two legs respectively. Figure 12b and Figure 12c Similarly, occupants can individually adjust the inflation level of each inflatable cushion 32 according to actual conditions, thereby changing the firmness of the corresponding area of ​​the cushion. For example, this is suitable for situations where the pressure applied to the cushion along the width of the seat is uneven when the occupant is reclining, and the hips and legs have different support needs.
