By utilizing the second rebound portion 37, when the backrest 2 rotates at an angle greater than 30°, the second contactor 39 can be effectively prevented from squeezing the first contactor 38 and causing damage.

[0045] Working process: When in use, first start the battery. The user sits inside the seat with his back leaning against the backrest 2. The first rebound part 21 is used to make the surface of the backrest 2 fit the user's back. At the same time, the user can use the control display screen to control the bulge of the headrest part 1, so that the headrest part 1 fits the user's neck more closely, avoiding the neck from being suspended in the air and affecting the user's health. When the user needs to rest in a lying or semi-lying state, the control display screen is used to start the drive part 4, which in turn drives the backrest 2 and the leg support part 8 to work together to relax the user's legs, which is more in line with the ergonomic design. At the same time, the backrest support part 3 can be used to avoid the phenomenon of the seat being overweight when the backrest 2 is rotated, causing the seat to tilt and causing danger. After use, turn off the battery.
