Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a seat and vehicle. Background Technology

[0002] Existing seats typically include a seat frame, a seat cushion, and a lifting device. Both the seat cushion and the lifting device are located within the seat frame, with the lifting device situated between the seat frame and the seat cushion.

[0003] The seat frame includes a seat basin, a support member, a seat cushion spring, and two side panels. The seat basin is located in front of the support member, with the two spaced apart. The front ends of the two side panels are connected to the left and right sides of the seat basin, respectively, and the rear ends of the two side panels are connected to the left and right sides of the support member, respectively. The seat basin includes a support plate and a connecting plate connected to the rear end of the support plate and extending downward and backward. The front end of the seat cushion spring is connected to the lower end of the connecting plate, and the rear end of the seat cushion spring is connected to the support member.

[0004] After assembly, the seat, support, seat spring, and two side plates form a recessed space. At least a portion of the support plate forms the seat bearing area, and at least a portion of the seat spring forms the seat spring bearing area. The seat spring bearing area is located below and behind the seat bearing area and at the bottom of the recessed space.

[0005] The lifting device is located on the seat spring and is situated within the spring support area. A portion of the seat cushion is also located on the lifting device within the spring support area, while another portion is situated on the support plate within the seat basin support area.

[0006] In addition, the lifting device is connected to the inflation / deflation device so that it can receive the inflation / deflation operation of the inflation / deflation device and thus deform. Specifically, when the lifting device receives the inflation operation of the inflation / deflation device, it can expand, thereby raising the seat cushion; when the lifting device receives the deflation operation of the inflation / deflation device, it can contract, thereby lowering the seat cushion.

[0007] However, in existing seats, when the lifting device is inflated, it causes a large drop between the front of the occupant's thighs and the seat cushion, making the occupant more prone to fatigue. Utility Model Content

[0041] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] like Figures 1 to 5 As shown, in one embodiment, the seat includes a seat frame 10, a seat cushion 20, and a lifting device 30; the seat frame 10 has a spring-supporting area 101 and a basin-supporting area 102, the spring-supporting area 101 being located below and behind the basin-supporting area 102; at least a portion of the seat cushion 20 is disposed above the lifting device 30, the spring-supporting area 101, and the basin-supporting area 102; the area of ​​the seat cushion 20 above the spring-supporting area 101 is adapted to support the buttocks of the occupant, and the area of ​​the seat cushion 20 above the basin-supporting area 102 is adapted to support the thighs of the occupant; the lifting device 30 includes a lifting component 1 and a support component 2, the support component 2 being located above the lifting component 1, and both the lifting component 1 and the support component 2 having deformable areas that can deform during inflation and deflation; the deformable area of ​​the lifting component 1 is disposed above the spring-supporting area 101 and the basin-supporting area 102; the deformable area of ​​the support component 2 is disposed above the spring-supporting area 101.

[0045] The area of ​​the seat cushion 20 above the seat spring bearing area 101 is defined as the first riding area, and the area of ​​the seat cushion 20 above the seat basin bearing area 102 is defined as the second riding area. The first riding area is located behind the second riding area.

[0046] The phrase "both the lifting component 1 and the support component 2 have deformation areas that can deform during inflation and deflation" can mean that the deformation area of ​​the lifting component 1 can expand and deform during inflation, and the deformation area of ​​the lifting component 1 can contract and deform during deflation; the deformation area of ​​the support component 2 can expand and deform during inflation, and the deformation area of ​​the support component 2 can contract and deform during deflation.

[0047] "The seat spring bearing area 101 is located behind and below the seat basin bearing area 102" means that the seat spring bearing area 101 is located behind the seat basin bearing area 102 and below the seat basin bearing area 102.

[0048] "Support component 2 is located above lifting component 1" can mean that the deformation area of ​​support component 2 is above the deformation area of ​​lifting component 1.

[0049] In this embodiment, when the lifting component 1 of the lifting device 30 is inflated, the deformation area of ​​the lifting component 1 expands, thereby raising the seat cushion 20. Since the deformation area of ​​the lifting component 1 is located above the seat spring bearing area 101 and above the seat basin bearing area 102, the deformation area of ​​the lifting component 1 is located below both the first and second seating areas. Therefore, when the deformation area of ​​the lifting component 1 expands, both the first and second seating areas can be raised, thereby effectively avoiding the problem of a large drop between the front of the occupant's thigh and the seat cushion 20.

[0050] In addition, the deformation zone of the support component 2 can also deform during inflation and deflation. Using it in conjunction with the lifting component 1 can give the lifting device 30 more control space, thereby improving the user experience of the seat.

[0051] For example, in real-world scenarios, to raise the seat cushion 20, the deformation zone of the lifting component 1 needs to have a large air pressure. The hardness of the deformation zone of the lifting component 1 is usually large, which leads to poor seating comfort. In this case, if the deformation zone of the support component 2 is inflated and has a small air pressure, thus making it more flexible (at this time, the lifting effect of the deformation zone of the support component 2 on the height of the first seating area is not obvious), the user experience can be improved.

[0052] For example, in real-world scenarios, there may be passengers with shorter statures. Simply relying on the lifting component 1 might not be enough to meet their needs; for instance, a low seat cushion 20 might obstruct the driver's field of vision. In this case, in addition to raising the seat cushion 20 using the lifting component 1, the deformation area of ​​the support component 2 can be used to further raise the height of the first seating area. This maximizes the passenger's ability to accommodate the seat cushion 20's height requirements, thereby increasing the driver's field of vision, compensating for their visual limitations, and reducing driving hazards.

[0053] Furthermore, in existing technologies, when passengers rest, they adjust the seat back to recline, creating a significant height difference between the points where the backrest and the body meet, and between the seat cushion and the body. This results in the tailbone area being unsupported, causing significant stress concentration in the lower back and leading to discomfort. In this embodiment, by appropriately adjusting the inflation of the lifting component 1 and the support component 2, the height difference between the points where the backrest 40 and the body meet, and between the seat cushion 20 and the body meet, can be eliminated, reducing stress concentration in the lower back and improving comfort.

[0054] like Figure 2 and Figure 3 As shown, the seat frame 10 includes a seat basin 3, a support member 4, a seat cushion spring 5, and two side plates 6. The seat basin 3 is located in front of the support member 4, and the two are spaced apart. The front ends of the two side plates 6 are respectively connected to the left and right sides of the seat basin 3, and the rear ends of the two side plates 6 are respectively connected to the left and right sides of the support member 4. The seat basin 3 includes a support plate 31 and a connecting plate 32 connected to the rear end of the support plate 31 and extending downward and backward. The front end of the seat cushion spring 5 is connected to the lower end of the connecting plate 32, and the rear end of the seat cushion spring 5 is connected to the support member 4.

[0055] like Figure 2 and Figure 4 As shown, after assembly, the seat basin 3, support member 4, seat cushion spring 5 and two side plates 6 form a recessed space 7. At least a portion of the support plate 31 forms the seat basin bearing area 102, and at least a portion of the seat cushion spring 5 forms the seat spring bearing area 101. The seat spring bearing area 101 is located below and behind the seat basin bearing area 102 and at the bottom of the recessed space 7.

[0056] After assembly, the part of the deformation area of ​​the lifting component 1 located in the seat spring bearing area 101 is located inside the recessed space 7, and the part of the deformation area of ​​the lifting component 1 located in the seat bearing area 102 is located outside the recessed space 7.

[0057] Furthermore, when the deformation zone of the lifting component 1 is not inflated, at least a portion of the deformation zone of the support component 2 may be located within the recessed space 7. When the deformation zone of the lifting component 1 is inflated, the support component 2 may be located either within or outside the recessed space 7.

[0058] In addition, the backrest 40 is connected to the support member 4 and can rotate relative to the seat frame 10 with the support member 4 as the axis, thereby adjusting the tilt angle of the backrest.

[0059] The axis of the support member 4 is parallel to the left-right direction. The support member 4 may include a rotating shaft and a sleeve. The rotating shaft rotatably connects to two side plates 6 around its own axis. The sleeve is fitted over the rotating shaft and does not rotate relative to the side plates 6 after being connected to them. The rotating shaft is connected to the backrest 40; when the rotating shaft rotates, it drives the backrest 40 to rotate. Of course, in some scenarios, the rotating shaft may not rotate relative to the side plates 6. In this case, the rotating shaft is rotatably connected to the backrest, and the backrest 40 can rotate relative to the rotating shaft around its axis. The axis of the rotating shaft is the axis of the support member 4.

[0060] In one embodiment, the seat cushion 20 is positioned entirely above the lifting device 30, which facilitates the production and manufacturing of the seat.

[0061] It should be noted that the related settings and assembly methods of the seat frame 10, seat cushion 20 and backrest 40 can all be existing designs.

[0062] like Figure 7 As shown, in one embodiment, the lifting assembly 1 includes a first air bag 11 and a second air bag 12; both the first air bag 11 and the second air bag 12 are deformable when inflated or deflated; the first air bag 11 is located above the seat spring bearing area 101 and behind the seat basin bearing area 102; the second air bag 12 is located above the first air bag 11 and protrudes forward from the first air bag 11; the portion of the second air bag 12 that protrudes forward from the first air bag 11 is located above the seat basin bearing area 102.

[0063] It should be understood that the area where the first air bag 11 can deform during inflation and deflation and the area where the second air bag 12 can deform during inflation and deflation both belong to the deformation zone of the lifting component 1.

[0064] Moreover, "the first air bag 11 is located above the seat spring bearing area 101" actually means that the area of ​​the first air bag 11 that can deform during inflation and deflation is located above the seat spring bearing area 101.

[0065] In this embodiment, the first air bag 11 is located below the second air bag 12. When the first air bag 11 is inflated, it can raise the height of the part of the second air bag 12 located above the seat spring bearing area 101, thereby reducing the height difference between this part and the part of the second air bag 12 located above the seat basin bearing area 102, which is beneficial to the inflation and deflation deformation of the second air bag 12.

[0066] In one embodiment, the first air bag 11 and the second air bag 12 are connected to each other for easy assembly.

[0067] like Figure 7As shown, in one embodiment, the second air bag 12 includes a first inflation / deflation deformation portion 121 and a second inflation / deflation deformation portion 122; the first inflation / deflation deformation portion 121 is disposed above the first air bag 11; the second inflation / deflation deformation portion 122 is disposed above the basin support area 102.

[0068] The first inflation / deflation deformation section 121 and the second inflation / deflation deformation section 122 can both expand during inflation and contract during deflation. Both the first inflation / deflation deformation section 121 and the second inflation / deflation deformation section 122 belong to the deformation zone of the lifting component 1.

[0069] In addition, the first inflation / deflation deformation part 121 is located above the first air bag 11, which means that it is located above the seat spring bearing area 101. The first inflation / deflation deformation part 121 is located above the seat spring bearing area 101, and the second inflation / deflation deformation part 122 is located above the seat basin bearing area 102. This allows the lifting component 1 to be located above both the seat spring bearing area 101 and the seat basin bearing area 102 at the same time.

[0070] In this embodiment, the first air bag 11 is located below the first inflation / deflation deformation part 121. When the first air bag 11 is inflated, the height of the first inflation / deflation deformation part 121 can be raised to reduce the height difference between the first inflation / deflation deformation part 121 and the second inflation / deflation deformation part 122, thereby facilitating the inflation of the first inflation / deflation deformation part 121 and the second inflation / deflation deformation part 122.

[0071] In one embodiment, the first inflation / deflation deformation section 121 and the second inflation / deflation deformation section 122 are connected, and inflation of the other can be achieved by inflating one of them. Similarly, deflation of the other can be achieved by deflating one of them.

[0072] like Figure 7 As shown, in one embodiment, the second air bag 12 further has a partition 123 located between the first inflation / deflation deformation portion 121 and the second inflation / deflation deformation portion 122; a receiving cavity for inflation / deflation is formed inside the second air bag 12; a portion of the receiving cavity is located in the first inflation / deflation deformation portion 121, a portion of the receiving cavity is located in the second inflation / deflation deformation portion 122, and a portion of the receiving cavity is located in the partition 123; the partition 123 has at least one connecting area 124; in the connecting area 124, the upper and lower cavity walls of the receiving cavity are fitted together.

[0073] Inflating the second air bag 12 is essentially inflating the receiving cavity, while deflating the second air bag 12 is essentially expelling the gas from the receiving cavity. The upper and lower cavity walls being joined together can mean either welding them together or using adhesives or other methods. It is understood that the joint area is not used for gas flow.

[0074] Furthermore, the first inflation / deflation deformation section 121, the second inflation / deflation deformation section 122, and the partition section 123 each have a portion of the receiving cavity. The first inflation / deflation deformation section 121, the second inflation / deflation deformation section 122, and the partition section 123 are interconnected, and all three can deform during inflation / deflation. The first inflation / deflation deformation section 121 and the second inflation / deflation deformation section 122 are connected through the partition section 123.

[0075] By setting the connecting area 124, the deformation of the partition 123 can be limited, preventing it from expanding too much, and the second air bag 12 can be closer to the desired shape after inflation.

[0076] In the actual product, the partition 123 can be inclined vertically and covers the connecting plate 32 of the seat 3. The lower end of the partition 123 is connected to the front end of the first inflation / deflation deformation part 121, and the upper end of the partition 123 is connected to the rear end of the second inflation / deflation deformation part 122.

[0077] It should be understood that the first inflation / deflation deformation section 121 may also have at least one joint area 124, and the second inflation / deflation deformation section 122 may also have at least one joint area 124. In addition, the first air bag 11 may also have at least one joint area.

[0078] In one embodiment, the first air bag 11 and the second air bag 12 are connected. Inflating one of them allows inflation of the other. Similarly, deflating one allows deflating the other.

[0079] In the actual product, the first air bag 11 and the first inflation / deflation deformation section 121 can be directly connected via an air pipe or other means. During inflation, external gas can first enter the first air bag 11, then the first inflation / deflation deformation section 121, then the partition section 123, and then the second inflation / deflation deformation section 122. During deflation, the gas in the second inflation / deflation deformation section 122 first enters the partition section 123, then the first inflation / deflation deformation section 121, then the first air bag 11, and then is discharged from the first air bag 11. Of course, in the actual product, the gas flow pattern during inflation and deflation can also be other, which will not be elaborated upon in this embodiment.

[0080] In one embodiment, the lifting component 1 is a double-layered airbag, comprising a first airbag 11 and a second airbag 12 connected to each other. The first airbag 11 is the first layer of the double-layered airbag, and the second airbag 12 is the second layer. Furthermore, the first airbag 11 and the second airbag 12 are connected together, and they can be connected by welding or bonding. Of course, in some scenarios, the connection between the first airbag 11 and the second airbag 12 can also be achieved.

[0081] like Figure 7 As shown, in one embodiment, the support component 2 includes a third air bag 21 and a fourth air bag 22, both of which are deformable during inflation and deflation; the third air bag 21 is located above the lifting component 1, and the fourth air bag 22 is located above the third air bag 21.

[0082] It should be understood that the areas where the third airbag 21 can deform during inflation and deflation, and the areas where the fourth airbag 22 can deform during inflation and deflation, both belong to the deformation zone of the support component 2.

[0083] "The third airbag 21 is located above the lifting assembly 1, and the fourth airbag 22 is located above the third airbag 21" means that the area of ​​the third airbag 21 that can deform during inflation and deflation is located above the deformation area of ​​the lifting assembly 1, and the area of ​​the fourth airbag 22 that can deform during inflation and deflation is located above the area of ​​the third airbag 21 that can deform during inflation and deflation. Furthermore, the third airbag 21 and the fourth airbag 22 are located above the seat spring bearing area 101.

[0084] The configuration of this embodiment can make the support component 2 more flexible and can also make the support component 2 lift the first seating area of ​​the seat cushion 20 to a greater height.

[0085] In the example where the lifting assembly 1 includes a first air bag 11 and a second air bag 12, the first air bag 11, the second air bag 12 (specifically the first inflation / deflation deformation part 121), the third air bag 21, and the fourth air bag 22 are stacked sequentially from bottom to top.

[0086] In one embodiment, the third air bag 21 and the fourth air bag 22 are connected to each other, thereby facilitating assembly.

[0087] In one embodiment, the third air bag 21 and the fourth air bag 22 are connected. Inflating one of them allows inflation of the other. Similarly, deflating one allows deflating the other.

[0088] In one embodiment, the support component 2 is a double-layered airbag, which includes a third airbag 21 and a fourth airbag 22 that are connected to each other. The third airbag 21 is the first layer of the double-layered airbag, and the fourth airbag 22 is the second layer. Furthermore, the third airbag 21 and the fourth airbag 22 are connected together, and they can be connected by welding or bonding. Of course, in some scenarios, the connection between the third airbag 21 and the fourth airbag 22 can also be achieved.

[0089] like Figure 7 As shown, in one embodiment, the lifting component 1 has a first buffer notch 13, and the deformation zone of the lifting component 1 is broken at the first buffer notch 13. When the lifting component 1 is inflated, the lifting component 1 will expand and compress the surrounding space. The first buffer notch 13 can be used to avoid the expansion of the lifting component 1, so that the shape of the lifting component 1 after the collision can meet the predetermined requirements.

[0090] like Figure 7 As shown, when the lifting assembly 1 includes a first air bag 11 and a second air bag 12, a first notch 111 is formed on the first air bag 11 and the assembly is broken at the first notch 111; a second notch 125 is formed on the second air bag 12 and the assembly is broken at the second notch 125.

[0091] At this time, the first buffer gap 13 includes a first gap 111 and a second gap 125. "The deformation zone of the lifting component 1 is broken at the first buffer gap 13" means that the first air bag 11 is broken at the first gap 111 and the second air bag 12 is broken at the second gap 125.

[0092] Furthermore, the first airbag 11 breaks at the first notch 111, which actually means that the deformable area of ​​the first airbag 11 breaks at the first notch 111. The second airbag 12 breaks at the second notch 125, which actually means that the deformable area of ​​the second airbag 12 breaks at the second notch 125.

[0093] like Figure 7 As shown, the first notch 111 extends rearward to cut off the first air bag 11, causing the rear portion of the first air bag 11 to break off. At this time, the first air bag 11 includes a first branch 112, a second branch 113, and a first converging portion 114, wherein the first branch 112 and the second branch 113 are both connected to the rear end of the first converging portion 114, and the first branch 112 and the second branch 113 are spaced apart, and the first branch 112, the second branch 113, and the first converging portion 114 surround to form the first notch 111.

[0094] The first gap 111 is located between the first branch 112 and the second branch 113, and belongs to the space between the first branch 112 and the second branch 113. In addition, the first branch 112, the second branch 113 and the first gathering part 114 all belong to the deformation area of ​​the lifting assembly 1.

[0095] like Figure 7 As shown, the second notch 125 extends rearward to cut off the second air bag 12, causing the rear portion of the second air bag 12 to break off. At this time, the second air bag 12 includes a third branch 126, a fourth branch 127, and a second converging portion 128. The third branch 126 and the fourth branch 127 are both connected to the rear end of the second converging portion 128, and the third branch 126 and the fourth branch 127 are spaced apart. The third branch 126, the fourth branch 127, and the second converging portion 128 enclose and form the second notch 125.

[0096] The second gap 125 is located between the third branch 126 and the fourth branch 127, and belongs to the space between the third branch 126 and the fourth branch 127. In addition, the third branch 126, the fourth branch 127 and the second gathering part 128 all belong to the deformation area of ​​the lifting assembly 1.

[0097] In addition, the second notch 125 is located above the seat spring bearing area 101, the third branch 126 and the fourth branch 127 are both part of the first inflation / deflation deformation area, a part of the second collection part 128 belongs to the first inflation / deflation deformation part 121, and another part of the second collection part 128 belongs to the second inflation / deflation deformation part 122.

[0098] like Figure 7 As shown, in one embodiment, the support component 2 has a second buffer notch 23, and the deformation zone of the support component 2 is interrupted at the second buffer notch 23. When the support component 2 is inflated, the support component 2 expands and compresses the surrounding space. The second buffer notch 23 can be used to avoid the expansion of the support component 2, so that the shape of the support component 2 after the collision can meet the predetermined requirements.

[0099] like Figure 7 As shown, when the support assembly 2 includes a third air bag 21 and a fourth air bag 22, a third notch 211 is formed on the third air bag 21 and the assembly breaks at the third notch 211; a fourth notch 221 is formed on the fourth air bag 22 and the assembly breaks at the fourth notch 221.

[0100] At this time, the second buffer gap 23 includes the third gap 211 and the fourth gap 221. "The deformation zone of the support component 2 is broken at the first buffer gap 13" means that the third air bag 21 is broken at the third gap 211 and the fourth air bag 22 is broken at the fourth gap 221.

[0101] Furthermore, the fact that the third airbag 21 breaks at the third notch 211 actually means that the deformable area of ​​the third airbag 21 breaks at the third notch 211. Similarly, the fact that the fourth airbag 22 breaks at the fourth notch 221 actually means that the deformable area of ​​the fourth airbag 22 breaks at the fourth notch 221.

[0102] like Figure 7 As shown, the third notch 211 extends rearward to cut off the third air bag 21, causing the rear portion of the third air bag 21 to break off. At this time, the third air bag 21 includes a fifth branch 212, a sixth branch 213, and a third converging part 214. The fifth branch 212 and the sixth branch 213 are both connected to the rear end of the third converging part 214, and the fifth branch 212 and the sixth branch 213 are spaced apart. The fifth branch 212, the sixth branch 213, and the third converging part 214 enclose and form the third notch 211.

[0103] The third gap 211 is located between the fifth branch 212 and the sixth branch 213, and belongs to the space between the fifth branch 212 and the sixth branch 213. In addition, the fifth branch 212, the sixth branch 213 and the third converging part 214 all belong to the deformation zone of the lifting assembly 1.

[0104] like Figure 7 As shown, the fourth notch 221 extends rearward to cut off the fourth air bag 22, causing the rear portion of the fourth air bag 22 to break off. At this time, the fourth air bag 22 includes a seventh branch 222, an eighth branch 223, and a fourth converging part 224. The seventh branch 222 and the eighth branch 223 are both connected to the rear end of the fourth converging part 224, and the seventh branch 222 and the eighth branch 223 are spaced apart. The seventh branch 222, the eighth branch 223, and the fourth converging part 224 enclose and form the fourth notch 221.

[0105] The fourth gap 221 is located between the seventh branch 222 and the eighth branch 223, belonging to the space between the seventh branch 222 and the eighth branch 223. In addition, the seventh branch 222, the eighth branch 223 and the fourth converging part 224 all belong to the deformation zone of the lifting assembly 1.

[0106] like Figure 7As shown, in one embodiment, when the lifting assembly 1 includes a first air bag 11 and a second air bag 12 connected together, and the support assembly 2 includes a third air bag 21 and a fourth air bag 22 connected together, and the first air bag 11, the second air bag 12, the third air bag 21, and the fourth air bag 22 are stacked sequentially from bottom to top, the lifting assembly 1 further includes a first flexible connecting portion 14, which connects to the two side walls of the second notch 125 respectively; the support assembly 2 further includes a second flexible connecting portion 24, which connects to the two side walls of the third notch 211 respectively, and connects to the first flexible connecting portion 14. This allows the lifting assembly 1 and the support assembly 2 to be connected together, thereby facilitating the assembly of the lifting device 30 with the seat frame 10.

[0107] The first flexible connecting part 14 is located within the second notch 125 and is not connected to the second air bag 12, so it will not inflate. When the second air bag 12 inflates, the first flexible connecting part 14 deforms due to its flexibility, thereby reducing interference with the inflation of the second air bag 12.

[0108] The material of the first flexible connecting part 14 is the same as that of the second air bag 12, and the two can be an integral structure. In this case, the first flexible connecting part 14 is equivalent to an area on the second air bag 12 that cannot be inflated or deflated.

[0109] Furthermore, the second flexible connection 24 is located within the third notch 211 and is not connected to the third air bag 21, so it will not inflate. When the third air bag 21 inflates, the second flexible connection 24 deforms due to its flexibility, thereby reducing interference with the inflation of the third air bag 21.

[0110] The material of the second flexible connection part 24 is the same as that of the third air bag 21, and the two can be an integral structure. In this case, the second flexible connection part 24 is equivalent to an area on the third air bag 21 that cannot be inflated or deflated.

[0111] Furthermore, both the first flexible connecting part 14 and the second flexible connecting part 24 can be made of plastic, and the two can be connected together by welding or bonding.

[0112] In one embodiment, the seat further includes an inflation / deflation device connected to the lifting assembly 1 and the support assembly 2, capable of independently inflating and deflating the lifting assembly 1 and the support assembly 2. This allows for individual control of the lifting assembly 1 and the support assembly 2, facilitating user operation. Furthermore, when the lifting assembly 1 and the support assembly 2 are in the raised state, the air pressure within the lifting assembly 1 is greater than the air pressure within the support assembly 2. This ensures that the seat cushion 20 is raised while making the seat softer, thereby improving the riding experience.

[0113] "When the lifting component 1 and the support component 2 are in a lifting state" means that the lifting component 1 is in an inflated state and the support component 2 is in an inflated state.

[0114] The inflation / deflation device for the lifting component 1 means that the inflation / deflation device can both inflate and deflate the lifting component 1.

[0115] The inflation / deflation device for the support component 2 means that the inflation / deflation device can both inflate and deflate the support component 2.

[0116] like Figure 6 As shown, in one embodiment, the lifting device 30 encloses and forms a clearance channel 201; the clearance channel 201 extends through the lifting device 30 in the vertical direction and is adapted to avoid the blower; wherein, the clearance channel 201 is opposite to the seat spring bearing area 101. This can reduce interference with the blower.

[0117] The air blowing device is also part of the seat, including an air blowing bag, an air pipe and a fan. The air blowing bag can be set between the seat cushion 20 and the lifting device 30. The fan is connected to the air blowing bag through the air pipe. The fan can be located below the seat spring, and the air pipe passes through the clearance passage 201.

[0118] When the fan is working, it can blow air into the air bag, which in turn blows air onto the seat cushion 20. This air can pass through the seat cushion 20 and reach the top of the seat cushion 20 to blow air onto the occupant on the seat cushion 20. Alternatively, when the fan is working, it can draw air from the air bag, which causes the air above the seat cushion 20 to pass through the seat cushion 20 and enter the air bag, and then be drawn away by the fan. This can also create airflow above the seat cushion 20 to form a breeze, which can then blow air onto the occupant on the seat cushion 20.

[0119] The inflation / deflation device and the blower can both be existing technologies.

[0120] In addition, such as Figure 7 As shown, the clearance channel 201 forms a first through hole 115 on the first air bag 11, a second through hole 129 on the second air bag 12, a third through hole 215 on the third air bag 21, and a fourth through hole 225 on the fourth air bag 22.

[0121] Furthermore, the first through hole 115 is connected to the first notch 111, making the hole wall of the first through hole 115 an open-loop structure; the second through hole 129 is connected to the second notch 125, making the hole wall of the second through hole 129 an open-loop structure; the third through hole 215 is connected to the third notch 211, making the hole wall of the third through hole 215 an open-loop structure; and the fourth through hole 225 is connected to the fourth notch 221, making the hole wall of the fourth through hole 225 an open-loop structure.

[0122] like Figure 7 As shown, in one embodiment, the lifting device 30 further includes a first support plate 81, which is disposed between the seat spring support area 101 and the lifting assembly 1 to isolate the lifting assembly 1 from the seat spring support area 101. This can prevent the lifting assembly 1 from contacting and rubbing against the seat spring 5, effectively preventing wear of the lifting assembly 1 and improving its service life.

[0123] Specifically, the first bearing plate 81 is located between the first air bag 11 and the seat spring bearing area 101. The first bearing plate 81 can be a felt board, etc.

[0124] The lifting device 30 also includes a second support plate 82, which is disposed between the lifting component 1 and the seat bearing area 102 to isolate the seat bearing area 102 of the lifting component 1. This can prevent the lifting component 1 from contacting and rubbing against the support plate 31, effectively preventing wear of the lifting component 1 and improving the service life of the lifting component 1.

[0125] Specifically, the second support plate 82 is located between the second inflation / deflation deformation section 122 of the second air bag 12 and the support plate 31. The second support plate 82 can be a felt board, etc.

[0126] In one embodiment, the first support plate 81 and the second support plate 82 can be connected together, in which case they can be an integral structure. Of course, the first support plate 81 and the second support plate 82 can also be separated and not connected, in which case they are two independent parts.

[0127] Alternatively, the lifting assembly 1 may be connected to the first support plate 81 and the second support plate 82.

[0128] In addition, the avoidance channel 201 forms a fifth through hole 811 on the first bearing plate 81.

[0129] like Figure 7 As shown, in one embodiment, the seat frame 10 further includes a leg rest 9, which is connected to the support plate 31 and located in front of the support plate 31; the leg rest 9 can be used to support the occupant's lower legs. Additionally, a portion of the seat cushion 20 can cover the leg rest 9. Furthermore, the leg rest 9 can be an existing technology.

[0131] It should be understood that the above-mentioned settings can also be replaced in other ways, such as:

[0132] In other embodiments, the lifting device 30 may also be located inside the seat cushion 20, in which case only a portion of the seat cushion 20 is located above the lifting device 30.

[0133] In other embodiments, the first air bag 11 and the second air bag 12 can be two independent air bags, in which case they are not connected. Moreover, both the first air bag 11 and the second air bag 12 are connected to an inflation / deflation device so that the first air bag 11 and the second air bag 12 can be independently inflated or deflated by the inflation / deflation device.

[0134] In other embodiments, the first inflation / deflation deformation section 121 and the second inflation / deflation deformation section 122 can be two independent air bags, which are not connected to each other. Moreover, both the first inflation / deflation deformation section 121 and the second inflation / deflation deformation section 122 are connected to an inflation / deflation device so that the first inflation / deflation deformation section 121 and the second inflation / deflation deformation section 122 can be independently inflated and deflated by the inflation / deflation device.

[0135] In other embodiments, the third air bag 21 and the fourth air bag 22 can be two independent air bags, in which case they are not connected. Moreover, both the third air bag 21 and the fourth air bag 22 are connected to an inflation / deflation device so that the third air bag 21 and the fourth air bag 22 can be independently inflated or deflated by the inflation / deflation device.

[0136] In other embodiments, the number of air bags in the lifting component 1 can also be other values, such as having only one air bag or having two or more air bags, in which case the air bags are arranged sequentially from top to bottom.

[0137] In other embodiments, the number of air bags in the support component 2 can also be other values, such as having only one air bag or having two or more air bags, in which case the air bags are arranged sequentially from top to bottom.
