By inflating the airbag, the front surface of the seat cushion is raised to fit more closely with the front of the departure point of the occupant's thigh, so that the front of the occupant's thigh receives more support than the seat cushion on a regular seat. The adaptive airbag assembly (10) at the rear of the seat cushion is located near the departure point behind the occupant's thigh. By inflating the airbag, the rear surface of the seat cushion is raised to fit more closely with the rear of the departure point of the occupant's thigh, so that the rear of the occupant's thigh receives more support than the seat cushion on a regular seat. The adaptive airbag assembly (8) at the top of the backrest is located near the departure point of the occupant's backrest. By inflating the airbag, the top surface of the backrest is raised to fit more closely with the upper part of the departure point of the occupant's backrest, so that the upper part of the occupant's backrest receives more support than the backrest on a regular seat.

7. The multifunctional integrated adaptive seat system according to claim 3, characterized in that, The adaptive airbag assembly (8), the right backrest wing support assembly (2), the left backrest wing support assembly (3), and the adaptive airbag lumbar support assembly (5) on the seat back correspond to the corresponding sections on the occupant's back, and automatically adjust the pressure inside the airbags. The airbags inflate to provide automatic support for the occupant's back.

8. The multifunctional integrated adaptive seat system according to claim 3, characterized in that, The adaptive airbag assembly (10) at the rear end of the seat cushion and the adaptive airbag assembly (12) at the front end of the seat cushion correspond to different zones of the occupant's buttocks, and automatically adjust the pressure inside the airbags. The airbags inflate to provide automatic support for the occupant's buttocks.

9. The multifunctional integrated adaptive seat system according to claim 3, characterized in that, After the occupant sits down, the seat cushion occupant weight recognition device OCS (11) recognizes that an occupant has sat down, detects the corresponding weight level of the occupant, and outputs a signal to the backrest adaptive control ECU (9); the backrest A-side sensing pad (1) recognizes the sensing type of the backrest and outputs a signal to the backrest adaptive control ECU (9). Under the overall scheduling of the backrest adaptive control ECU (9), the backrest top adaptive airbag assembly (8), the backrest right wing support assembly (2), the backrest left wing support assembly (3), and the backrest adaptive airbag lumbar support assembly (5), as well as the seat cushion rear adaptive airbag assembly (10) and the seat cushion front adaptive airbag assembly (12), automatically adjust the airbag pressure of each of the above assemblies to the target pressure and maintain the pressure, providing full-range comfortable support for the occupant's back and buttocks at the corresponding positions on the seat.
