Seat Belt Reminder

Seat Belt Reminder - SBR

An effective way to increase seat belt usage

Our Seat Belt Reminder (SBR) sensor mat detects occupants in passenger and rear seats. This information is then used by a seat belt reminder system in the vehicle to trigger a warning light and/or an audible chime reminding unbuckled seat occupants to fasten their seat belts.

Installing Seat Belt Reminders can also have a positive effect on the vehicle’s NCAP star rating, with incentives currently awarded by the European, Japanese, Australian, Chinese, Latin American, ASEAN and South Korean NCAPs. The upcoming Bharat NCAP (India) is also expected to offer SBR incentives.

IEE offers:

  • A-surface SBR sensors mounted on top of the seat cushion foam; below the seat heater and the seat trim
  • B-surface SBR sensors mounted below the seat cushion foam on top of the seat structure
  • For rear seats, an optional interface box to communicate the SBR and buckle-switch status via single Local Interconnect Network (LIN) interface to the Airbag Control Unit (ACU)

In the event of a crash, safety belts reduce the risk of fatal injury to front seat occupants by 45% in cars and by 60% in light trucks. Considering 80% of unbuckled occupants fasten their seat belts thanks to an SBR, it is one of the most effective ways of preventing death or injury in a car crash.
