[0056] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "install", "connect", "connect", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0057] The seat pad and its application scenarios disclosed in the embodiments of the present application are based on car seats as an example. However, it can be understood that the seat pad of this case is applicable to scenarios other than seats of vehicles such as cars, and can also be used for seats in fixed places, such as massage chairs, seats for audience seats at large events and conferences, office chairs, etc.

[0058] refer to Figures 1 to 3 As shown, a vehicle 10000 has a seat 1000, and the seat 1000 includes a seat cushion 1001 and a backrest 1002. The seat cushion 1001 and the backrest 1002 are common components of the seat 1000, that is, the backrest 1002 is mainly used to support the back and waist of the passenger, and the seat cushion 1001 is mainly used to support the buttocks and thighs of the passenger.

[0059] The seat pad 100 described in detail in the following embodiments is arranged inside the seat cushion 1001 and / or the backrest 1002. Here, the seat pad 100 is arranged inside the backrest 1002 as an example. Figure 3 As shown, the seat cushion 100 is disposed at the lower portion of the backrest 1002 of the seat 1000, so that the seat cushion 100 corresponds to the waist of the occupant of the seat 1000 as a lumbar support and provides massage and cushioning effects on the waist to enhance the comfort experience of the occupant.

[0060] like Figure 4 as well as Figure 5 As shown, in some embodiments, the seat cushion 1001 and / or the backrest 1002 of the seat 1000 have a substrate 1003, which is generally located inside the seat 1000. The back side of the substrate 1003 can be covered with a skin. The substrate 1003 provides a boundary for the seat cushion 1001 and / or the backrest 1002 on the back side, and the seat pad 100 is installed and fixed to the substrate 1003.

[0061] like Figure 1 As shown, taking the substrate 1003 being located inside the backrest 1002 as an example, in some embodiments, the backrest 1002 of the seat 1000 is provided with a seat cushion 100, and the backrest 1002 is provided with a substrate 1003, the substrate 1003 provides a boundary of the backrest 1002 on the back side, the seat cushion 1000 is mounted and fixed on the substrate 1003, and the backrest 1002 is directly adjacent to the storage space 2000 of the vehicle. The meaning is generally that, for example, in a hatchback-type vehicle such as an SUV or a commercial vehicle, the seat 1000 The rear part is directly the luggage space of the trunk, rather than a three-box body structure with a passenger compartment with seats and an independent luggage compartment, but this is not limited to it. For example, a structure in which a substrate is provided for the seat cushion 1001 is not excluded. That is, in some embodiments, the seat cushion 1001 of the seat 1000 may be provided with a seat cushion 100, and the seat cushion 1001 may be provided with a substrate 1003. The substrate 1003 provides a boundary for the seat cushion 1001 on the back side, and the seat cushion 100 is mounted and fixed on the substrate 1003. The seat cushion 1001 is arranged directly adjacent to the storage space 2000 of the vehicle.

[0062] In order to increase the storage space 2000 as much as possible, the seat with a base plate 1003 generally has a smaller distance X from the surface side to the back side inside. The seat pad 100 introduced in the following embodiment allows the hollow body to be reliably supported by the support panel while reducing the hard feeling of the seat pad to the occupant when the hollow body is not expanded. The hollow body can also be arranged inside the seat at a position close to the seat surface. It is particularly suitable for situations where the installation space is limited and the size of the backrest or seat cushion from the surface side to the back side is small. In this case, the hard feeling caused by the unexpanded state of the hollow body can be reduced.

[0063] like Figures 3 to 7 As shown, in some embodiments, the seat pad 100 includes a hollow body 1, a middle portion 2, and a support panel 3 which are stacked in sequence.

[0064] The hollow body 1 includes a hollow body 11 and a first connecting portion 12. The hollow body 11 can be filled with fluid to expand. The specific form of the hollow body 11 can be an inflatable air bag as shown in the figure, that is, the fluid filled is air or other safe gas. When the hollow body 11 (that is, the air bag here) needs to be expanded, the air pump delivers air to the air bag. It can be understood that the fluid filled with the hollow body can also be in other forms, for example, it can also be a liquid, that is, the hollow body is filled with liquid to expand, and the device for pumping the fluid is a liquid pump. The specific structure can be Figure 6 , Figure 7 As shown, the hollow body 11 is an air bag. When not inflated, the air bag is a flat structure as shown in the figure, supported by the middle part 2 and the support panel 3. It can be understood that the specific form of the hollow body 11 can be a single large hollow body or a plurality of small hollow bodies, and is not limited thereto. The first connecting portion 12 is independent of the hollow body 11 to avoid affecting the fluid tightness of the hollow body 11.

[0065] like Figure 5 As shown, the seat 1000 further includes a fluid pump 6 and a pipeline 7, wherein the fluid pump 6 is fluidically connected to the hollow body 11 through the pipeline 7, so that the fluid pump 6 can deliver or discharge the fluid that expands the hollow body 11. The position of the fluid pump 6 can be Figure 4As shown, the backrest 1002 is located, that is, the fluid pump 6 and the pipeline 7 and the seat cushion 100 are all located on the backrest 1002, but this is not limited to it. For example, the fluid pump 6 and the pipeline 7 may be located at one of the backrest 1002 and the seat cushion 1001, and the seat cushion 100 is located at the other. For another example, the backrest 1002 and the seat cushion 1001 are both provided with the modified seat cushion 100, and the fluid pump 6 and the pipeline 7 may be located at one of the backrest 1002 and the seat cushion 1001, or the fluid pump 6 and the pipeline 7 may be located at both the backrest 1002 and the seat cushion 1001. The specific structure can be arranged according to the actual pumping demand and the spatial layout requirement of the seat.

[0066] The middle part 2 includes a middle part body 21 and a second connecting part 22. The middle part body 21 is a flexible component and the second connecting part 22 is a rigid component. The meaning of "main body" in the middle part body 21 here is not to provide the main surface area of ​​the middle part corresponding to the hollow body 1, such as more than 70% of the surface area. The support panel 3 includes a support panel body 31 and a third connecting part 32. The support panel body 31 is a rigid component. The above concepts of flexible components and rigid components are relative, rather than absolute flexibility and rigidity. The meaning of flexibility is that the thickness of the components will be deformed by the riding action of the passengers during operation, which can be observed by the naked eye. For example, it can be a foamed part, such as a polyurethane foaming process. The flexible component can also be a relatively soft component. Relatively speaking, the meaning of the rigid component is that the riding action of the passengers during operation will not cause obvious deformation of its thickness. The rigid component can be plastic, such as PP plastic, engineering plastic, etc. The structure of the support panel 3 can be a flat plate structure with a flat surface as shown in the figure, a curved surface structure, or a partially hollowed structure, which is not limited to this.

[0067] In some embodiments, the second connection part 22 is a plastic part, the middle part body 21 is a foam part, and the support panel 3 is a plastic part. The beneficial effect of this is that it is easy to form a structure in which the second connection part 22 and the middle part body 21 are integrally connected, and the middle part body 21 and the second connection part 22 can be integrally formed by insert injection molding. In addition, the cost of using plastic parts is also low. However, this is not a limitation, for example, the rigid component can also be a metal part, a composite material part, etc.

[0068] like Figure 3 As shown, the stacking direction of the hollow body 1, the middle part 2, and the support panel 3 inside the seat cushion 1001 and / or the backrest 1002 is that the hollow body 1, the middle part 2, and the support panel 3 are stacked in sequence in the direction from the surface 10010 of the seat cushion 1001 and / or the backrest 1002 to the back. Figure 3In the seat shown, the stacking direction of the hollow body 1, the middle part 2, and the support panel 3 inside the seat cushion 1001 and / or the backrest 1002 is that the hollow body 1, the middle part 2, and the support panel 3 are stacked in sequence in the direction from the surface side of the seat cushion 1001 and / or the backrest 1002 to the back side. It can be understood that the sequential stacking here only represents the relative positional relationship between the hollow body 1, the middle part 2, and the support panel 3, and does not completely exclude the possibility of arranging other components between the hollow body 1, the middle part 2, and the support panel 3.

[0069] Continue to refer Figures 5 to 7 As shown, in some embodiments, the specific structures of the first connection part 12, the second connection part 22, and the third connection part 32 can be that the first connection part 12, the second connection part 22, and the third connection part 32 include connection holes 5 aligned in the stacking direction, and the connection member 4 can sequentially connect the connection holes 5 of the first connection part 12, the second connection part 22, and the third connection part 32 in the stacking direction to connect the hollow body 1, the middle part 2, and the support panel 3. The connection member 4 can be, for example, a screw-shaped component as shown in the figure, and its material can be a plastic part, but it is not limited thereto. The beneficial effect of this is that the connection structure is simple and easy to assemble.

[0070] Continue to refer Figures 5 to 7 As shown, in some embodiments, the specific structure of the second connecting part 22 may include a strip-shaped body 221 and a connecting hole 5 opened in the strip-shaped body 221. The strip-shaped body 221 of the second connecting part 22 is located on both sides of the middle part main body 21 in the width direction, which is easy to process and the second connecting part 22 can provide stable and reliable connection and support.

[0071] In summary, the beneficial effects of the seat pad, seat and vehicle described in the above embodiments include but are not limited to: by setting an intermediate portion between the hollow body of the seat pad and the support panel, the intermediate portion includes the structure of the intermediate portion main body of the flexible component and the second connecting portion of the rigid component, so that the hollow body can be reliably supported by the support panel while reducing the hard feeling of the seat pad to the occupant when the hollow body is not expanded, and the hollow body can also be set inside the seat at a position close to the seat surface, so that the seat pad can provide a good massage and cushioning effect to the occupant when the hollow body expands, and is also reliably supported inside the seat. Improve the comfort of the occupant, and is particularly suitable for the situation where the seat is directly adjacent to the storage space in the vehicle.
