The pressure sensor is installed at one end of the housing, and one end of the trigger spring is fixedly connected to the housing, and its free end extends toward the pressure sensor. The trigger spring is arched. When the trigger spring is squeezed, its free end will trigger the pressure sensor, and the pressure sensor sends a signal to the car computer, indicating that a user has sat on the seat cushion. At this time, the seat belt monitoring unit detects that the user has not fastened the seat belt, and the car computer will remind the user that the seat belt is not fastened through the warning unit. In order to realize the fixing of the sensor device in the seat cushion, the prior art adopts a fixed connection adapter plastic bracket at the bottom of the housing, and then the adapter plastic bracket is connected to the seat suspension spring steel wire through a buckle.

[0036] Two opposite sides of the mounting seat body 1 are respectively provided with a main connection sleeve 2 , the main connection sleeve 2 is integrally connected with the mounting seat body 1 by injection molding, and the main connection sleeve 2 extends along the length direction of the mounting seat body 1 .

[0038] The utility model provides a pressure sensor mounting seat, which is used to install a pressure sensor device in a seat cushion 8 of a car seat, and the pressure sensor device includes a pressure sensor 5 (micro switch) and a sensor trigger spring 6. When the foam body in the seat cushion 8 is subjected to downward pressure, the foam body squeezes the sensor trigger spring 6, and the sensor trigger spring 6 is deformed to trigger the pressure sensor 5. The pressure sensor 5 is connected to the vehicle computer to send a signal to the vehicle computer, indicating that a user sits on the seat cushion 8.
