[0052] In this embodiment, multiple pressure sensors are distributed along multiple vertically intersecting longitudinal tracks and transverse tracks to cover the area where the headrest assembly contacts the head to the greatest extent, so that when any user cooperates with the headrest assembly, the pressure sensors can detect pressure changes.

[0053] The signal line of the pressure sensor passes through the headrest foaming assembly and the headrest inverted rod and is connected to the control module 5 , so that the collected pressure information can be transmitted to the control module 5 .

[0054] The remaining structures of the headrest assembly 2 can be made by using the existing technology and will not be described in detail here.

[0055] In this embodiment, the air pump 4, the control module 5 and the corresponding circuits are all arranged inside the backrest assembly 1, without occupying the space of the rest of the car. There is no need to reserve installation space for the control module 5, the air pump 4 and the corresponding circuits in the rest of the car, and there is no need to redesign. The improvement of the car backrest is simpler and low-cost, which reduces the design difficulty, workload and cost.

[0056] In some other embodiments, the airbag 301 is composed of multiple layers distributed up and down, and each layer of airbags is connected to a switching valve through an air pipe. The switching valve is arranged at the interface of the air pump to realize the switching of inflation and deflation of different airbags.

[0057] This arrangement enables adjustment of the vertical inflatable portion of the airbag to meet the neck support needs of users of different heights and physiques.

[0058] Example 2

[0059] This embodiment provides a method for manufacturing the automobile seat backrest with integrated neck pillow as described in Embodiment 1, comprising the following steps:

[0060] Step 1: After fixing the airbag 301 and the airbag fixing plate 302, fix it to the top of the pre-made backrest frame assembly 101 through the airbag fixing bracket 303, install the control module 5 in the middle position of the backrest spring of the backrest frame assembly 101, install the air pump 4 at the bottom of the side panel on one side of the backrest frame assembly 101, connect the control line between the control interface of the air pump 4 and the control module 5, and connect the interface of the air pump 4 to the charging and discharging port of the airbag 301 through the air pipe.

[0061] Step 2: Assemble the headrest assembly 2, assemble the headrest foam assembly and the headrest frame assembly, the assembly method can be done by the existing technology, which will not be described in detail here, then glue and fix the pressure sensor in the fixing groove of the headrest foam assembly, pass the signal line of the pressure sensor through the headrest foam assembly and the headrest inverted rod, cover the headrest cover on the outside of the formed overall structure, the headrest inverted rod passes through the headrest cover, and the headrest cover is covered manually, using the existing technology, which will not be described in detail here. After the headrest assembly 2 is assembled, connect the signal line of the pressure sensor to the control module 5.

[0062] Step 3: After step 2 is completed, the backrest foaming assembly 102 is assembled on the backrest frame assembly 101. The assembly method can be based on existing technology and will not be described in detail here.

[0063] Step 4: After the backrest foam assembly 102 is assembled, the backrest foam assembly 102 and the backrest frame assembly 101 form an integral assembly structure, and then the cover assembly 103 is covered on the integral assembly structure to complete the assembly of the entire backrest assembly. The covering method of the cover assembly 103 can be adopted by the existing technology, which will not be described in detail here.

[0064] Step 5: Finally, assemble the headrest assembly 2 to the backrest assembly 1 through the headrest inverted rod, and the assembly of the entire car seat back is completed.

[0065] Example 3

[0066] This embodiment provides a method for operating the automobile seat backrest with an integrated neck pillow as described in Embodiment 1:

[0067] The pressure sensor detects the pressure value of the headrest assembly 2 in real time. When the pressure value detected is greater than the set value, it means that the user is sitting on the seat and the user's head applies pressure to the headrest assembly. At this time, the control module 5 sends an inflation command to the air pump 4 to control the operation of the air pump 4. The air pump 4 inflates the air bag 301, and the air bag expands and cooperates with the user's neck to play the role of a neck pillow.

[0068] In one embodiment, the amount of air that the air pump inflates the air bag is a set constant amount, which can be set according to actual needs and will not be described in detail here.

[0069] In another embodiment, when the head contacts the headrest assembly and presses against the corresponding pressure sensor on the headrest assembly, the height and weight of the corresponding person are identified, the relative position of the corresponding person's neck is identified, and then the distance between the headrest and the person's neck is calculated, the distance required to support the neck is calculated, and finally the airbag is inflated, and inflation is stopped when the calculated height is reached.

[0070] In this embodiment, a test is conducted in advance, and the pressure on the headrest is collected by a pressure sensor after people of different heights and weights sit on the seat, and a database of pressure, human height and weight, and the distance between the human neck and the headrest assembly is established. The data in the database are fitted to obtain a relationship model between pressure and people of different heights and weights, and then a relationship model between pressure and the headrest and the distance between the human neck is obtained based on the human body structure. In this way, the distance between the headrest and the human neck can be obtained based on the data from the pressure sensor, and the air bag can be inflated based on the distance. Inflation stops when the target inflation volume is reached.

[0071] In a third embodiment, a pressure sensor may be provided on the side of the inflatable neck pillow assembly that contacts the human neck. When the pressure sensor detects pressure, the air pump stops inflating.

[0072] When the user leaves the seat, the head no longer applies pressure to the headrest assembly. At this time, the pressure sensor detects that the pressure value is less than the set value, and the control module 5 sends a vacuum instruction to the air pump 4 to control the operation of the air pump 4. The air pump 4 vacuums the air bag 301, and the air bag 301 shrinks to its initial state and does not occupy the space in front of the backrest.

[0073] In the working method of this embodiment, the control module 5 automatically controls the inflation and exhaust of the air pump 4 through the detection value of the pressure sensor, without the need for the user to manually send instructions to the control module 5, thus satisfying the requirement of arranging the control module 5 inside the backrest assembly 1, while making it more convenient for the user to operate and optimizing the user experience.

[0075] This embodiment provides a car seat, which is provided with a car seat backrest with an integrated neck pillow as described in Embodiment 1. The remaining structure of the car seat can adopt the existing technology and will not be described in detail here.

[0076] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
