Seat Belt Reminder SBR - IEE

Seat Belt Reminder - SBR
The Seat Belt Reminder sensor mat detects occupants in passenger and rear seats. A seat
belt reminder system in the vehicle triggers a warning light and/or an audible chime,
reminding unbuckled seat occupants to fasten their seat belts.
Seat belt reminders save lives
Seat belts are part of a passive safety system and are mainly intended to reduce injuries
by preventing car occupants from hitting hard interior elements of the vehicle, hitting other
passengers or being ejected from the vehicle. 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. 1
Considering 80% of unbuckled occupants put on their seat belt when reminded by an
SBR 2 , it is one of the most effective ways of reducing risk of death or injury in a car crash.
Enhanced NCAP rating
Installing Seat Belt Reminders can have a positive effect on the
vehicle’s NCAP 3 score. SBR points are awarded by Euro NCAP,
Japan NCAP and China NCAP, and SBR equipment is a precondition
for a top rating by ASEAN NCAP, in South East Asia, and by ANCAP
in Australia. Latin NCAP (South/Central America) has announced
similar incentives for the future.
The overall rating system introduced by the Euro NCAP in 2009
shifted the SBR points to the safety assist category, where they now
play a significant role in fulfilling the requirements for a 5-star – or
maximum – overall rating.

Key Advantages
• Precision. IEE’s SBR sensor mat is available in different layouts depending on the
detection accuracy needed to differentiate between people and objects.
• Easy seat integration. The design of our technology is highly flexible, making it easy to
insert the mat into either the A or B surface of the vehicle seat.
• Cost-efficiency. Our development cycles are short and our replacement procedures
simple. There is no need for any initial calibration or recalibration during the entire
lifetime of the sensor mat.
• Added value. The sensor mat can be used for other occupant-related comfort functions,
including seat heater switches.
• Reliability. The sensor maintains robust performance regardless of temperature, humidity
and age. It is not affected by seat adjustments, repositioning or shocks and vibrations.
• Experience. IEE has gathered unparalleled car seat know-how due to long-standing
partnerships with seat manufacturers worldwide. Our SBRs have been installed in over
50 million vehicles across the globe.

About Us
The IEE Seat Belt Reminder consists of a sensor mat inserted in the vehicle
seat and is based on a technology which uses variable resistance to measure
pressure applied to sensor cells.
The mat itself is composed of two sandwiched carrier sheets held together
by an adhesive. Increased pressure on the sensor mat causes an electrical
resistance change, which tells the system that the seat is occupied. The seat
belt reminder system is automatically activated and visually and/or audibly
reminds the occupant to buckle up.
The key advantage of using force sensing cells is their extreme efficiency.
The technology is also designed for thin applications, which is crucial for a
sensor mat that needs to be flexible in order to be inserted into the vehicle
seat.
IEE is an innovative developer of specialized sensing systems. Our sensing technologies
are dedicated to the following markets: Transportation & Automotive, Public & Commercial
Infrastructure, Consumer and Medical & Healthcare.
IEE was founded in 1989 and is headquartered in Luxembourg. We operate in Europe, the
U.S. and Asia, and employ 1,600 people worldwide. More than 10% of our workforce is
dedicated to Research and Development.
