It can be understood that the above scheme can be used when adjusting the surface shape of the headrest 102, and can also be used when driving the rotating seat 106 to rotate.

[0026] According to this specific embodiment, the headrest 102 is disposed on the top of the seat body 101 , and the adjustment assembly 103 can adjust the angle and height of the headrest 102 to accommodate different passengers.

[0027] The first electric push rod 104 is connected to the seat body 101 and is located inside the seat body 101. The fixed seat 105 is arranged on the first electric push rod 104 and is connected to the output end of the first electric push rod 104. The rotating seat 106 is rotatably connected to the fixed seat 105 and is fixedly connected to the headrest 102 and is arranged on the fixed seat 105. The air storage shell 107 is fixedly connected to the headrest 102 and is located inside the headrest 102. The airbag 108 is connected to the air storage shell 107, is in communication with the air storage shell 107, and is located on one side of the air storage shell 107.
