What is car seat pressure membrane sensor

What is car seat pressure membrane sensor ?
Seat belt reminder is a kind of membrane type contact sensor. The contacts of sensor evenly distribute on the stress-bearing surface of seat, will generate a trigger signal when the external force presses on the seat. It apply to the car seat occupant perception system, such as safety belt reminder , taxi automatic message accounting system, airbag’s sensor, condition that the driver leaves seat. For example, with this device, occupancy sensor can detect if anybody sits or not, and the airbag won’t open if nobody. It can also design the dimension of sensors and sensitivity of contacts as the shape and hardness of car seat.

Product Description

1. Thin film pressure sensor;

2. When the seat is not sitting, the sensor is disconnected, that is, the resistance is infinite;

3. When the seat is seated, the sensor is switched on, and the resistance is ≤ 100Ω.

4. The thickness of the film pressure sensor can be customized according to customers

Seat Pressure Sensor

1. Safety belt reminder system: It is a system that reminds the passenger of the car when the passenger of the car is not wearing seat belts.

2. Occupant detection system of vehicle safety belt reminder: Installed in the motor vehicle seat, it is composed of the sensing device, a wiring harness, and a connecting device, and is used to judge the occupancy of an occupant on the seat.

3. Detection device: It is a kind of test equipment used to capture the signal of the sensing device and reflect the occupancy status of the occupant or the non-occupancy of the object detected by the sensing device in the form of sound and light. For example, the occupant occupancy indicator light is on, otherwise, the indicator light is off.

4. Detection: When the sensing device detects that the seat is occupied by an occupant, the detection device indicates the occupant occupancy status.

5. Non-detectability: When the sensing device detects that the seat is not occupied by the occupant, the detection device indicates that the object is not occupied.

Working principle: The detection system consists of an electronic control unit (ECU), a seat belt reminder device (SBR), and a seat belt lock. It can detect the occupancy of passengers in the seat and the non-occupancy of objects, and decide whether to turn on the lights or sound warnings to remind passengers to fasten their seat belts.
