Automobile Seat Occupancy Sensors



Linepro’s Automobile Seat Occupancy Sensor is best solution for overall passenger safety and Driver Assistance system. Seat Occupancy sensors facilitate monitoring of conditions of seats in terms of nature of occupancy. Modern vehicles being equipped with seat belts and airbags, Linepro’s sensors determine whether the seat belts are into use and the airbags properly deployed during a wreck; depending on the passenger occupying the seat.

At Linepro, we ensure the sensors are fool-proof, no matter what the working condition may be, our sensors go through stringent quality checks like temperature tests, waterproof tests, voltage resistance tests. With the manufacturing process at our own facility, high performance of automobile seat occupancy sensors is guaranteed!

Seat Occupancy Monitoring System

Every Modern Car is equipped with passenger airbags and adheres to International Safety norms for automobiles. With increasing cars on roads day-by-day, the number of accidents increase in proportion. There are larger number of accidents which consists of unnecessary airbag deployment, although the passenger seat is unoccupied. Such airbags account to increased repair costs in an unjustified manner, as they are repaired or replaced with new ones. The ultimate solution for waste of repair costs can be addressed by means of Seat Occupancy monitoring systems (SOMS) installed in the passenger seat.

Working of Seat Occupancy Monitoring System

The SOMS is made of array of sensors whose resistance changes with applied force. The dimensions of the sensor array mat are tailored to match the seat design. Since the sensor mat has design flexibility, it can be mounted in different ways as:

• Between seat shell and the foam

• Between seat foam and cover

Membrane Switches and Keypads

When a seat is occupied, the resistance changes and this change is measured by means of integrated electronic controller system. When any seat is unoccupied the airbag cum ignition circuit is switched off when resistance of sensor lies between two pre-defined values. If the resistance value is other than the pre-defined value, it is concluded by the system that the seat is occupied and the airbag cum ignition circuit is ready to be deployed during a wreck.
