[0002] With the development of the automotive industry, more and more car seats are beginning to use pneumatic seat support to provide passengers with a more comfortable riding experience. Currently, there are many styles of car seats on the market, and the arrangement of seat support varies greatly. However, the support layout is basically limited to the lumbar region, lacking overall coverage. Some seats also have support mechanisms on the sides of the driver and passengers. Even so, there is still a gap between the back and sides, preventing the back and side support mechanisms from working together. This leads to discomfort and a lack of conformity to the curvature of the back during riding. Furthermore, when the car seat turns, it can easily cause significant swaying or displacement of the body, and if the acceleration and frequency are fast enough, it can even cause injury.

[0034] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this invention.

[0035] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0036] As mentioned in the background section, in order to solve the problems existing in the prior art, this embodiment provides a car seat surround support structure, which is set on the support body 4 of the car seat. The car seat includes a back support area 1, a linkage support area 2 and a side support area 3. The linkage support area 2 is located between the back support area 1 and the side support area 3.

[0037] The supporting structure includes:

[0038] The back support mechanism is located on the support body 4 and corresponds to the back support area 1 of the car seat, and is used to provide support for the back of the passenger.

[0039] The auxiliary support mechanism consists of two auxiliary support mechanisms located on both sides of the back support mechanism along the first direction, corresponding to two linked support areas 2, which are used to provide support for the part between the sides of the occupant's body and the back.

[0040] like Figure 1-3 As shown, the first direction is the width direction of the car seat, and the second direction is the height direction of the car seat. The car seat can be divided into a back support area 1, a side support area 3, and a linkage support area 2 located between the two. The linkage support area 2 has a seat side groove 13 connecting the back support area 1 and the side support area 3. The support body 4 can be a seat frame or other supportive structures in the car seat. The support body 4 is covered with a support 8, which is used to support the passenger. The support 8 can be seat foam, including backrest foam and side wing foam. The two side wing foams are located on both sides of the backrest foam, and the backrest foam and side wing foam are separated by the seat side groove 13. The back support mechanism and the auxiliary support mechanism are both located on the support body 4, inside the support 8. Other devices that can improve seat comfort can also be set between the support mechanism and the support 8, such as... Figure 3 The ventilation bag 14 shown in the figure; when sitting, due to the presence of the seat side groove 13 and the arrangement of the back support mechanism and the side wing support mechanism, it can often only lift part of the backrest foam and the side wing foam, which causes the linkage support area 2 to not be able to fully fit the body of the passenger, and thus it is difficult to provide full coverage support for the passenger's waist and back. The auxiliary support mechanism is set in the linkage support area 2, that is, the area on both sides of the angle between the backrest foam and the side wing foam. The auxiliary support mechanism spans the seat side groove 13, with part of it located behind the backrest foam and part of it located behind the side wing foam. It can fully lift the backrest foam and the side wing foam to achieve full support for the passenger's waist and back.

[0041] The back support mechanism and auxiliary support mechanism can support the load 8 through mechanical transmission, or through pneumatic means such as air bags or air bladders, or through a combination of mechanical and non-mechanical methods. The back support mechanism and auxiliary support mechanism are used to make the parts of the load 8 corresponding to the occupant's waist and back fit the occupant's body, providing better support for the occupant's waist and back.

[0042] By setting auxiliary support mechanisms on both sides of the back support mechanism, support can be provided for the part between the back and the sides of the body of the passenger, so that the car seat can better conform to the curvature of the human back, provide better coverage for the human waist and back, avoid injury to the human body when the body sways or shifts, and greatly improve the passenger's riding comfort.

[0043] In a preferred embodiment, the support structure further includes side wing support mechanisms. Two side wing support mechanisms are symmetrically arranged on both sides of the back support mechanism, respectively corresponding to the two side wing support areas 3 of the car seat, for providing support to the sides of the occupant's body.

[0044] like Figure 1-3 As shown, the side support mechanism is located on the support body 1. It can also support the load 8 by mechanical transmission, pneumatic means such as air bags or air bladders, or a combination of mechanical and non-mechanical methods. The side support mechanism is used to make the parts of the load 8 corresponding to the sides of the passenger's body fit against the passenger's body, thereby achieving complete fit of the car seat against the sides and back of the passenger's body. The auxiliary support mechanism enables the side support mechanism and the back support mechanism to work together, thereby providing comprehensive support for the passenger's waist and back.

[0045] In a preferred embodiment, the back support mechanism is a back support bladder 100, and the auxiliary support mechanism is an auxiliary support bladder 200. The back support bladder 100 and the auxiliary support bladder 200 are connected to a pressurizing device 6 through a gas pipeline 5. The pressurizing device 6 is used to inflate the back support bladder 100 and the auxiliary support bladder 200.

[0046] In a preferred embodiment, the system further includes an elastic support plate 7, which is disposed on the support body 4. The elastic support plate 7 includes a first sub-plate 11 and two second sub-plates 12 connected to both ends of the first sub-plate 11 along a first direction. The first sub-plate 11 corresponds to the back support area 1, and the two second sub-plates 12 correspond to two linkage support areas 2 respectively. At least one back support bladder 100 is disposed on the first sub-plate 11, and at least two auxiliary support bladders 200 are symmetrically disposed on the two second sub-plates 12.

[0047] like Figure 2 and Figure 3As shown, the support body 4 is also provided with a support member 9. The support member 9 can be fixed to the support body 4 by hooking. The support member 9 is located on the support body 4 at a position corresponding to the back support area 1, and is used to support the elastic support plate 7. The elastic support plate 7 can be fixed to the support member 9 by sewing, welding or gluing. The elastic support plate 7 is used to set the back support bladder 100 and the auxiliary support bladder 200. The elastic support plate 7 includes a first sub-plate 11 and two second sub-plates 12 symmetrically connected to both ends of the first sub-plate 11. The second sub-plates 12 and the first sub-plate 11 have an included angle. Each independent support bladder includes multiple stacked and sequentially connected air bags. Each support bladder is connected to a gas pipe 5. Each support bladder can be connected to the pressurizing device 6 via an independent gas pipeline 5. The pressurizing device 6 is used to inflate the back support bladder 100 and the auxiliary support bladder 200. A control device 10 is also provided between the support bladder and the pressurizing device 6. The control device 10 is used to control the opening and closing of the gas pipeline 5 between the support bladder and the pressurizing device 6, thereby allowing the back support bladder 100 and the auxiliary support bladder 200 to be inflated / deflated or kept inflated. The gas pipeline 5 can be connected to the back support bladder 100 and the auxiliary support bladder 200 by welding. The pressurizing device 6 and the control device 10 can be installed on the elastic support plate 7, the support member 9, or the support body 4. The support member 9 can be the seat back spring.

[0048] The wing support mechanism can be a wing support capsule 300, such as... Figure 4 As shown, this is a car seat support structure in the prior art. The support body 4 is equipped with a back support bladder 100 and side support bladders 300. There is a gap between the back support bladder 100 and the side support bladders 300, which is the aforementioned linkage support area 2. The linkage support area 2 corresponds to the portion between the back and sides of the occupant's body. When the back support bladder 100 and the side support bladders 300 lift the load 8, the linkage support area 2 lacks a support mechanism, preventing the load 8 from forming a smooth support surface on the side closest to the occupant, thus failing to provide comprehensive support for the occupant's lower back. Figure 5 As shown, when the support body 4 is equipped with a back support bladder 100, an auxiliary support bladder 200, and a side support bladder 300, the back support area 1, the linkage support area 2, and the side support area 3 of the car seat can all receive good support, so that the load 8 has a smooth support surface on the side close to the passenger, and the car seat provides all-round coverage for the passenger's lower back; furthermore, as Figure 6As shown, the back support bladder 100, auxiliary support bladder 200, and side support bladder 300 are disposed on the support 8, that is, on the side of the seat foam closest to the passenger. The car seat is covered with a seat cover or other covering. In summary, the back support bladder 100, auxiliary support bladder 200, and side support bladder 300 can be disposed inside the support 8, located on the support body 4, or disposed on the side of the support 8 closest to the passenger. No special limitation is made here.

[0049] Figure 6 The image only shows the relative positional relationship between the back support bladder 100, the auxiliary support bladder 200, and the side support bladder 300 and the load 8. The specific structure inside the load 8 is not shown. The relevant structure inside the load 8 can be designed according to the actual situation, and no special limitation is made here.

[0050] In a preferred embodiment, the back support bladder 100 includes a plurality of first back support bladders 101, which are sequentially distributed on the first sub-plate 11 along a second direction perpendicular to the first direction.

[0051] In a preferred embodiment, the back support bladder 100 includes a plurality of second back support bladders 102, which are stacked and distributed on the first sub-plate 11 along a second direction perpendicular to the first direction.

[0052] In a preferred embodiment, the auxiliary support bladder 200 includes a plurality of first auxiliary support bladders 201, at least two of the first auxiliary support bladders 201 being sequentially distributed on the second sub-plate 12 along the second direction, or at least two of the first auxiliary support bladders 201 being integrally formed and disposed on the second sub-plate 12.

[0053] In a preferred embodiment, the auxiliary support bladder 200 includes a plurality of second auxiliary support bladders 202, at least two of which are sequentially distributed on the second sub-plate 12 along a first direction, or at least two of which are integrally formed and disposed on the second sub-plate 12.

[0054] like Figure 7-10As shown, the back support bladder 100 includes three first back support bladders 101, which are sequentially arranged on the first sub-plate 11 along the height direction of the car seat. Alternatively, the back support bladder includes three second back support bladders 102, which are sequentially stacked on the first sub-plate 11 along the height direction of the car seat, with the lower part of the upper second back support bladder 102 covering the upper part of the adjacent second back support bladder 102 below it. Furthermore, the back support bladder 100 can also be a single bladder, with one bladder covering the first sub-plate 11. In practical applications, the number of back support bladders 100 can be adjusted according to actual needs and is not specifically limited here. The auxiliary support bladder 200 includes four first auxiliary support bladders 201, which are symmetrically arranged... The two auxiliary support bladders 201 on each second sub-plate 12 are arranged sequentially along the height direction of the car seat, corresponding to the side grooves 13 of the seat. Alternatively, the auxiliary support bladder 200 may include four second auxiliary support bladders 202, which are symmetrically arranged on the two second sub-plates 12. The two second auxiliary support bladders 202 on each second sub-plate 12 are arranged sequentially along the width direction of the car seat, and the gap between the two second auxiliary support bladders 202 corresponds to the side grooves 13 of the seat. Furthermore, the two first auxiliary support bladders 201 or the two second auxiliary support bladders 202 may be integrally formed into one auxiliary support bladder 200, which also corresponds to the side grooves 13 of the seat. Similarly, the number of auxiliary support bladders 200 on each second sub-plate 12 may be adjusted according to actual needs, and no special limitation is made here.

[0055] In a preferred embodiment, the auxiliary support bladder 200 includes a plurality of third auxiliary support bladders 203, at least two of which are sequentially distributed on the second sub-plate 12 along the second direction. The two third auxiliary support bladders 203 symmetrical with respect to the first sub-plate 11 are respectively connected to or integrally formed with the first back support bladder 101 or the second back support bladder 102 between them.

[0056] like Figure 11 and Figure 12As shown, the auxiliary support bladder 200 includes four third auxiliary support bladders 203. The four third auxiliary support bladders 203 are symmetrically arranged on two second sub-plates 12. Two third auxiliary support bladders 203 on each second sub-plate 12 are arranged sequentially along the height direction of the car seat, corresponding to the side grooves 13 of the seat. The first sub-plate 11 may have three first back support bladders 101 arranged sequentially along the first direction, or three second back support bladders 102 stacked together. The two symmetrically arranged third auxiliary support bladders 203 are respectively connected to the first back support bladder 101 or the second back support bladder 102 between them, and are inflated and deflated through the same gas pipe 5. Alternatively, the two symmetrically arranged third auxiliary support bladders 203 and the first back support bladder 101 or the second back support bladder 102 between them are designed as an integral linked support bladder 400. The linked support bladder 400 extends from one end of the elastic support plate 7 to the other end along the width direction of the seat.

[0057] Furthermore, by setting up sensing devices and controlling them through the control device 10, independent pressure control between each support bladder can be achieved. For example, a gas pressure sensor can be set for each independent support bladder to monitor the internal air pressure value and adjust the corresponding support bladder according to the monitoring results. Alternatively, a pressure sensor can be set on the seat bearing surface to monitor the overall pressure on the seat bearing surface and adjust the corresponding support bladder accordingly. Multiple sensing devices can also be combined to improve monitoring accuracy. This application does not limit the specific sensors used. Therefore, the independently set back support bladder 100 and auxiliary support bladder 200 can achieve higher pressure control accuracy compared to the integrated support bladder. In actual use, the internal pressure of the lower support bladder is usually adjusted to be greater than that of the upper support bladder to achieve better human body support.

[0058] In a preferred embodiment, the back support bladder 100 further includes at least one third back support bladder 103, which is disposed on the support pivot of the support body 4, or multiple third back support bladders 103 are distributed along the second direction on the support pivot of the support body 4.

[0059] like Figure 13As shown, multiple third back support bladders 103 are disposed on the support body 4, starting from the position of the first back support bladder 101 or the second back support bladder 102 adjacent to the bottom of the first sub-plate 11, and arranged sequentially / stacked along the second direction to the support shaft of the support body 4. It should be noted that the number of third back support bladders 103 needs to be reasonably set according to the distance between the bottom of the first sub-plate 11 and the support shaft to ensure that the original back support area is not affected, while increasing the support function at the support shaft position, thereby expanding the back support area. When the support body 4 flips around the support shaft to the rear of the vehicle, the part between the first sub-plate 11 and the support shaft lacks support, so the third back support bladder 103 is disposed of in this manner. The third back support bladder 103 can effectively compensate for the above-mentioned support gap, so that the backrest of the car seat forms a flatter plane with the seat cushion when it is folded down, thereby improving the comfort of the seat and enhancing the passenger's riding experience. It should be noted that the third back support bladder 103 and the first back support bladder 101 or the second back support bladder 103 can be controlled by the same pressurizing device 6 and control device 10, or they can be controlled by independent pressurizing devices 6 and control devices 10 respectively. In other embodiments of this application, the third back support bladder 103 is not limited to being set on the support body 4 and the support pivot, and can also be set in other reasonable positions in other arrangements, which are not specifically limited here.

[0060] In a preferred embodiment, the back support mechanism is a back support member, the auxiliary support mechanism is an auxiliary support member, and the back support member and the auxiliary support member are connected to a driving member for transmission. The driving member can drive the back support member and the auxiliary support member respectively to provide support for the back area of ​​the occupant and the area between the sides of the body and the back.

[0061] like Figure 1 As shown, the back support mechanism, side support mechanism, and auxiliary support mechanism can all be set up using mechanical transmission. The side support mechanism also includes side support components. All three are set on the support body 4. The back support component corresponds to the back support area 1, the side support component corresponds to the side support area 3, and the auxiliary support component corresponds to the linkage support area 2. The driving component can drive the back support component, side support component, and auxiliary support component to rotate relative to the support body 4, thereby making the corresponding area on the load 8 fit against the passenger's body and support the passenger's body. Similarly, the back support component can also be set on the support pivot, or of course, it can be in other reasonable positions.
