Automobile Seat Occupancy Sensors
Thin flexible FSR mats for passenger safety and driver assistance. Airbag control, seat-belt monitoring and occupancy detection, tested for temperature, water and voltage.
What Are Seat Occupancy Sensors?
The seat occupancy monitoring system (SOMS) is an array of sensors whose resistance changes with applied force. The mat dimensions match the seat design and mount between shell and foam or between foam and cover.
When a seat is occupied the resistance shifts and an integrated controller reads the change. If the seat is empty the airbag circuit stays off and avoids unnecessary deployment and repair cost; if occupied, the airbag and ignition circuits stand ready.

Good to Know Before You Enquire
Three facts that shape your exact quotation.
The sensor mat is a tailored array whose resistance tracks force.
The controller compares readings against pre-defined values to decide occupied versus empty and arms the airbag and ignition circuits accordingly.
Design flexibility allows mounting between seat shell and foam or between foam and cover.
Laser cutting gives intricate patterns that follow the seat profile, with sizes up to 1000x1000 mm.
Sensors survive 100000 cycles in actual working conditions with low profile, light weight and low electrical resistance.
Stringent temperature, waterproof and voltage-resistance checks plus in-house manufacturing guarantee performance.
