Home/Seat Belt Reminder

Seat Belt Reminder System

An alert system that warns the driver and passenger with both sound and light when a belt is unfastened on an occupied seat, running in the same hub as the seat occupancy sensor.

Overview

A warning that won't fall silent until the belt is fastened

When the seat occupancy sensor sees a seat as occupied, the system continuously checks whether the belt on that seat is fastened. If it is not, the central unit starts an audible and visual alert that the driver and passenger cannot miss.

  • Because monitoring runs only on occupied seats, no needless alarm sounds for an empty seat.
  • Hundreds of different voice announcements and extra warning scenarios can be defined as needed.
  • Electronics that meet ECE R-10.05 and EMC test requirements.

FAQ

About the seat belt reminder system

If the seat belt is not fastened on an occupied seat, it warns the driver and passenger both audibly and visually. The warning continues until the belt is fastened, so belt use becomes a habit and the risk of injury in a possible accident is reduced.
It is used primarily in school buses, staff transport vehicles and ambulances, as well as bus, minibus and midibus class passenger vehicles. It is also adapted to heavy machinery such as forklifts, excavators, loaders and tractors. The system is configured according to the vehicle's seat count and use scenario.
Occupational health and safety regulations require operators of heavy machinery such as excavators, loaders, forklifts and tractors to fasten their seat belts. Producing audible and visual warnings when work begins without a fastened belt, our systems help fulfil on-site OHS obligations.
Yes. The seat belt reminder system is managed from the same central unit as the seat occupancy sensor. Because belt monitoring is done only on occupied seats, no unnecessary alarm sounds on empty seats.
No. The system performs belt monitoring only on seats the occupancy sensor detects as occupied. This prevents needless alarms originating from empty seats.
The electronics are developed to meet ECE R-10.05 and EMC test requirements. Hundreds of different voice announcements and warning scenarios can be defined as needed.
