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.

[0022] In the description of this utility model, it should be understood that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and 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, and therefore should not be construed as a limitation of this utility model.

[0023] 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.

[0024] like Figures 1 to 3 As shown, in one embodiment, the seat back 10 includes a backrest body 1 and an adapter component 2; the adapter component 2 is disposed in the backrest body 1 and includes a first air pipe 21, a first air connector 22 and a second air connector 23; the two ends of the first air pipe 21 are respectively connected to the first air connector 22 and the second air connector 23; the first air connector 22 is adapted to be pluggably connected to an external air-using device, and the second air connector 23 is adapted to be connected to an inflation / deflation device 30 so that the inflation / deflation device 30 can inflate or deflate the external air-using device.

[0025] Among them, the external gas-using equipment can be a neck pillow 20, etc.

[0026] In addition, in this application, "two objects can be plugged in and out" means that one of the two objects can be plugged in and engaged with the other, and after they are plugged in, they can be pulled out to separate them.

[0027] Specifically, the first gas connector 22 is suitable for pluggable connection to external gas equipment, meaning that the external gas equipment can be plugged into the first gas connector 22 to achieve connection and conduction between the two; moreover, when the two are connected, force can be applied to pull one of the external gas equipment and the first gas connector 22 out of the other to achieve separation between the two.

[0028] In the prior art, to install the neck pillow 20 on a seat, an additional air tube is required to connect the neck pillow 20 and the inflation / deflation device 30. Users are usually not professionals and often lack the necessary installation tools, making the connection and assembly of the neck pillow 20 and the inflation / deflation device 30 quite troublesome.

[0029] In this embodiment, the adapter component 2 is directly installed on the seat back. When in use, it is only necessary to plug and unplug the two ends of the adapter component 2 to connect the neck pillow 20 and the inflation / deflation device 30 respectively, so as to realize the connection between the neck pillow 20 and the inflation / deflation device 30, thus making it convenient for users to use.

[0030] Furthermore, since the adapter component 2 is pre-installed on the backrest body 1, when installing the neck pillow 20, there is no need to consider the placement of the corresponding air tubes, which can reduce the user's workload and make it more convenient for the user to use.

[0031] In addition, in this embodiment, the neck pillow 20 can be quickly and pluggably connected to the first air connector 22 of the adapter component 2, which facilitates the disassembly and assembly of the neck pillow 20 and the adapter component 2. This arrangement also facilitates the disassembly and assembly of the neck pillow 20, making it easy to remove the neck pillow 20 from the seat for cleaning and maintenance.

[0032] Meanwhile, placing the adapter 2 inside the backrest body 1 can effectively reduce the probability of the adapter 2 being scratched by external objects, which is conducive to ensuring its cooperation with external gas equipment and inflation / deflation devices.

[0033] Furthermore, the backrest body 1 can be the backrest in the prior art. The seat backrest 10 in this embodiment can be regarded as an additional adapter component 2 set in the existing backrest.

[0034] In one embodiment, the first gas connector 22 is a female connector with a quick-connect opening facing outwards from the backrest body 1; the quick-connect opening is adapted to allow the male connector of an external gas device to be inserted into and removed from the first gas connector 22; the second gas connector 23 is a male connector, adapted to be pluggably fitted with the female connector of the inflation / deflation device 30. This effectively prevents damage to the first gas connector 22. Moreover, by setting the first gas connector 22 and the second gas connector 23 as male and female respectively, their positions can be interchanged (or the connected objects can be interchanged) in some extreme cases, which can improve the adaptability of the adapter assembly 2 to different operating conditions.

[0035] like Figure 4 As shown, in one embodiment, the backrest body 1 is provided with a seat frame 11, and the first gas connector 22 is connected to the seat frame 11. The frame can provide rigid support for the first gas connector 22, facilitating its plug-in connection with external gas devices such as the neck pillow 20.

[0036] In addition, the backrest body 1 also includes a seat back cushion and a seat cover. The seat back cushion can be made of instant noodles or the like and is installed on the seat frame 11. The seat cover covers the seat back cushion and the seat frame 11.

[0037] In one embodiment, the seat cover 7 of the backrest body 1 is provided with a window, through which the quick-connect opening protrudes outward toward the outside of the seat back 10. That is, by providing a window, the seat cover can be prevented from obstructing the quick-connect opening, making it convenient for external air devices such as the neck pillow 20 to be connected to the first air connector 22.

[0038] In addition, in some scenarios, the seat back cushion also needs to be equipped with corresponding clearance holes or other structures so that the quick-connect opening can be exposed.

[0039] like Figure 4 As shown, in one embodiment, the seat backrest 10 further includes a mounting member 3, which is connected to the seat frame 11, and a first air connector 22 is connected to the mounting member 3. In this embodiment, the first air connector 22 is mounted on the seat frame 11 via the mounting member 3. Compared to directly mounting the first air connector 22 on the seat frame 11, this method facilitates the installation of the first air connector 22 and reduces the need for modifications to the seat frame 11 to accommodate the installation of the first air connector 22, thereby reducing production costs.

[0040] Alternatively, the mounting component 3 can be a sheet metal part, which can be detachably connected to the seat frame 11, for example, by bolts or the like. Of course, in some scenarios, the mounting component 3 can also be connected to the seat frame 11 by welding or other methods.

[0041] In addition, the first air connector 22 can be detachably installed on the mounting part 3 by means of bolts or the like, so as to facilitate the maintenance of the first air connector 22.

[0042] like Figure 6 and Figure 7 As shown, in one embodiment, the seat back 10 further includes a sealing cover 4, which is connected to the first air connector 22 and is used to open or close the quick-connect opening. When not in use, the quick-connect opening can be closed by the sealing cover 4, which can prevent dust and other debris from entering the first air connector 22, thus ensuring the working stability and service life of the first air connector 22.

[0043] When the sealing cover 4 opens the quick-connect opening ( Figure 7 The diagram shows the quick-connect interface when the sealing cover is open. External air supply equipment can be plugged into and disconnected with the first air connector 22. When the sealing cover 4 closes the quick-connect opening ( Figure 6 The diagram shown is a schematic of the quick-connect interface when the sealing cap is closed. External gas equipment cannot be used with the first gas connector 22.

[0044] In one embodiment, the sealing cap 4 is rotatably connected to the first air connector 22, and the quick-connect opening can be opened or closed by rotating the sealing cap 4.

[0045] In addition, a torsion spring or other elastic element is provided between the four first air connectors 22 of the sealing cover. When force is applied to the sealing cover 4 to rotate and open the quick-connect opening, the elastic element undergoes elastic deformation under the force; when the force applied to the sealing cover 4 is removed, the sealing cover 4 can be reset under the action of the elastic element, thereby closing the quick-connect opening.

[0046] In one embodiment, when the sealing cover 4 rotates inward toward the first air connector 22, the quick-connect opening can be opened; when the sealing cover 4 rotates outward, the quick-connect opening can be closed.

[0047] In one embodiment, a magnet is provided on the sealing cover 4 (or the sealing cover 4 itself is magnetic), and a magnet is provided on the connector of the external gas device (such as the third gas connector 53 below) (or it is magnetic itself), and the magnetism of the two is opposite. When the connector is close to the sealing cover 4, the magnetic forces of the two repel each other, thereby opening the sealing cover 4.

[0048] In one embodiment, the first air connector 22 is located at the top of the backrest body 1 to facilitate connection with the neck pillow 20 located at the upper end of the backrest body 1.

[0049] For example, the first air connector 22 is located at the top of the backrest body 1 near the top. At this time, the quick-connect interface faces the front of the backrest body 1, and the window on the seat cover is located on the A side of the backrest body 1. This makes it easier for the first air connector 22 to cooperate with the neck pillow 20 installed on the A side of the backrest body 1.

[0050] Of course, the quick-connect interface faces upwards from the backrest body 1, and in this case, the window on the seat cover is located above the backrest body 1. This makes it easier to utilize the space above the backrest body 1 (such as the space between the backrest body 1 and the headrest) and reduces the adverse effects of the neck pillow 20's air tube on the user.

[0051] Furthermore, the quick-connect interface faces the rear of the backrest body 1, at which point the window on the seat cover is located behind the backrest body 1. This reduces interference from surrounding objects when the neck pillow 20 is plugged in and out of the first gas connector 22, thus facilitating the plugging and unplugging of the neck pillow 20 and the first gas connector 22.

[0052] In one embodiment, the first air connector 22 is located above the second air connector 23, which also facilitates the connection of the second air connector 23 to the inflation / deflation device 30 located below the backrest body 1.

[0053] like Figure 5As shown, in one embodiment, the first gas connector 22 includes a connector seat 221 and a connector body 222; the connector seat 221 has a receiving through hole; the quick-connect opening is an opening at one end of the receiving through hole; the connector body 222 is located in the receiving through hole and is spaced apart from the quick-connect opening; the connector body 222 is connected to the first gas pipe 21, and the connector body 222 is pluggably connected to an external gas-using device that extends into the receiving through hole.

[0054] The connection seat 221 allows external pneumatic devices such as the neck pillow 20 to be easily guided to the connector body 222, thus facilitating their connection with the connector body 222.

[0055] Furthermore, the pluggable connection between the external air supply device of the neck pillow 20 and the first air connector 22 mainly refers to its pluggable connection with the connector body 222. The connector body 222 can be an existing air connector, which is assembled with the connector seat 221 to form the first air connector 22.

[0056] The connection between the sealing cap 4 and the first air connector 22 mainly refers to the connection between the sealing cap 4 and the connecting seat 221. When the sealing cap 4 rotates into the first air connector 22, it actually rotates into the receiving through hole.

[0057] The first air connector 22 is connected to the mounting part 3, which is actually the connecting seat 221 connected to the mounting part 3.

[0058] In one embodiment, the connector body 222 is snapped into the connector seat 221. At this time, the connector body 222 is provided with a locking block, and the connector seat 221 is provided with a locking hole, and the locking hole can communicate with the receiving through hole. When the connector body 222 extends into the receiving through hole, the locking block can be snapped into the locking hole.

[0059] The outer shell of the connector body 222 and the connector base 221 can both be made of plastic and have a certain degree of deformability.

[0060] In one embodiment, the first air tube 21, the connector body 222, and the second air connector 23 are connected to form a transfer air passage; the transfer assembly 2 includes at least one transfer air passage.

[0061] In this way, multiple external gas-using devices or multiple gas-using components of one external gas-using device can be connected to the gas filling and discharging device 30 respectively through the adapter component 2.

[0062] like Figure 2As shown, in one embodiment, the adapter assembly 2 further includes a first wire 24, a first electrical connector 25, and a second electrical connector 26; the two ends of the first wire 24 are electrically connected to the first electrical connector 25 and the second electrical connector 26, respectively; the first electrical connector 25 can be plugged into and detached to connect to an external gas-using device, and the second electrical connector 26 is adapted to connect to a power supply device 40 so that the power supply device 40 can supply and disconnect power to the external gas-using device.

[0063] The first electrical connector 25, when plugged into an external gas-using device, enables electrical connection between the two. Similarly, the second electrical connector 26, when connected to a power supply unit 40, enables electrical connection between the two.

[0064] When the external gas device is the neck pillow 20, it can be powered by the power supply device 40 to realize the heating function of the neck pillow 20.

[0065] In one embodiment, the first electrical connector 25 is a female connector and the second electrical connector 26 is a male connector. This effectively prevents damage to the first electrical connector 25. Moreover, by setting the first electrical connector 25 and the second electrical connector 26 as male and female respectively, their positions can be interchanged (or the connected objects can be interchanged) in some extreme cases, which can improve the adaptability of the adapter assembly 2 to different operating conditions.

[0066] In one embodiment, the first electrical connector 25 is integrated with the first gas connector 22 for ease of use.

[0067] Specifically, the first electrical connector 25 may be integrated with the connector body 222.

[0068] like Figure 2 As shown, in one embodiment, the adapter assembly 2 further includes a connector 27, through which the first electrical connector 25 and the connector body 222 are connected. The connector 27 is an injection-molded part, and the first electrical connector 25, the connector body 222, and the connector 27 can be integrally molded by injection molding for ease of production.

[0069] Subsequently, the connector 27 and the connector base 221 are connected by snap-fit ​​or other means, thereby achieving the connection between the connector body 222 and the connector base 221.

[0070] This utility model embodiment also provides a seat, which includes the seat back 10 described in any of the above embodiments.

[0071] In addition, the seat also includes a seat cushion, which is connected to the seat back 10. When the user sits on the seat cushion, he / she can lean against the seat back 10.

[0072] like Figure 1As shown, in one embodiment, the seat also includes a neck pillow 20, which is detachably connected to the backrest body 1. The neck pillow 20 includes a massage component 5, which includes a first air bag 51, a second air tube 52, and a third air connector 53. The two ends of the second air tube 52 are respectively connected to the first air bag 51 and the third air connector 53. The third air connector 53 can be plugged into and detached from the first air connector 22 so that the first air bag 51 can be inflated or deflated by the inflation / deflation device 30, thereby realizing the massage function of the neck pillow 20.

[0073] Among them, the neck pillow 20 can be the aforementioned external gas supply device.

[0074] Inflating and deflating the first air bag 51 includes inflating the first air bag 51 and deflating the first air bag 51. When inflating and deflating the first air bag 51, the first air bag 51 is kinetically deformable.

[0075] When the first air connector 22 is a female connector, the third air connector 53 is a male connector.

[0076] like Figure 2 , Figure 8 as well as Figure 9 As shown, in one embodiment, the neck pillow 20 further includes a heating component 6, wherein the heating component 6 includes a heating pad 61, a second wire 62 and a third electrical connector 63; the two ends of the second wire 62 are electrically connected to the heating pad 61 and the third electrical connector 63 respectively; the third electrical connector 63 is pluggably connected to the first electrical connector 25 of the adapter component 2.

[0077] By energizing the heating pad 61, it can generate heat, thereby heating the neck pillow 20 and improving the user experience.

[0078] When the third electrical connector 63 is connected to the first electrical connector 25, the two are electrically connected.

[0079] When the first electrical connector 25 is a female connector, the third electrical connector 63 is a male connector.

[0080] In one embodiment, the neck pillow 20 includes a firmness adjustment assembly, which further includes a second air bag, a third air tube, and a fourth air connector. The second air bag is located on the side of the first air bag 51 facing away from the heating pad 61. The two ends of the third air tube are respectively connected to the second air bag and the fourth air connector. The fourth air connector is pluggable and detachable to the first air connector 22. Both the fourth air connector and the third air connector 53 are male and are pluggable and detachable to the connector bodies 222 of different adapter air paths of the adapter assembly 2.

[0081] By inflating the second air bag with the inflation / deflation device 30, the firmness of the second air bag can be controlled, thereby improving the comfort of the neck pillow 20.

[0082] In addition, the first air bag 51 and the second air bag are respectively connected to different transfer air paths of the transfer assembly 2, which allows the inflation and deflation device 30 to control the two independently.

[0083] like Figure 8 and Figure 9 As shown, in one embodiment, the neck pillow 20 further includes a face cover 7 and an inner liner assembly 8; the heating pad 61, the first air bag 51, and the inner liner assembly 8 are all located inside the face cover 7 and arranged in sequence; the inner liner assembly 8 includes a first inner liner 81 and a second inner liner 82; the first inner liner 81 is located on the side of the first air bag 51 away from the heating pad 61, and the second inner liner 82 is located on the side of the first inner liner 81 away from the first air bag 51.

[0084] The first inner liner 81 and the second inner liner 82 can be made of appropriate materials and shapes according to actual needs, which is conducive to improving the use effect of the neck pillow 20.

[0085] The side of the first inner liner 81 opposite to the second inner liner 82 is typically curved to better support the user's neck. Furthermore, the first inner liner 81 may be made of memory foam for even better neck support.

[0086] The second inner liner, 82, can be made with biological materials, etc.

[0087] In addition, the surface of the first inner liner 81 opposite to the second inner liner 82 is provided with a receiving hole, and the first air bag 51 can be placed in the receiving hole. During massage, the first air bag 51 can extend out of the receiving hole after inflation; when not massaging, the first air bag 51 can be contained through the receiving hole, which helps to reduce or avoid problems such as bulges caused by the first air bag 51, so as to improve the user's comfort.

[0088] In one embodiment, the second air bag may be disposed between the first inner liner 81 and the second inner liner 82, or the second air bag may be disposed on the side of the second inner liner 82 opposite to the first inner liner 81.
