<strong>Seat</strong> <strong>Belt</strong> <strong>Reminder</strong> - <strong>SBR</strong><br />

The <strong>Seat</strong> <strong>Belt</strong> <strong>Reminder</strong> sensor mat detects occupants in passenger and rear seats. A seat<br />

belt reminder system in the vehicle triggers a warning light and/or an audible chime,<br />

reminding unbuckled seat occupants to fasten their seat belts.<br />

<strong>Seat</strong> belt reminders save lives<br />

<strong>Seat</strong> belts are part of a passive safety system and are mainly intended to reduce injuries<br />

by preventing car occupants from hitting hard interior elements of the vehicle, hitting other<br />

passengers or being ejected from the vehicle. In the event of a crash, safety belts reduce<br />

the risk of fatal injury to front seat occupants by 45% in cars and by 60% in light trucks. 1<br />

Considering 80% of unbuckled occupants put on their seat belt when reminded by an<br />

<strong>SBR</strong> 2 , it is one of the most effective ways of reducing risk of death or injury in a car crash.<br />

Enhanced NCAP rating<br />

Installing <strong>Seat</strong> <strong>Belt</strong> <strong>Reminder</strong>s can have a positive effect on the<br />

vehicle’s NCAP 3 score. <strong>SBR</strong> points are awarded by Euro NCAP,<br />

Japan NCAP and China NCAP, and <strong>SBR</strong> equipment is a precondition<br />

for a top rating by ASEAN NCAP, in South East Asia, and by ANCAP<br />

in Australia. Latin NCAP (South/Central America) has announced<br />

similar incentives for the future.<br />

The overall rating system introduced by the Euro NCAP in 2009<br />

shifted the <strong>SBR</strong> points to the safety assist category, where they now<br />

play a significant role in fulfilling the requirements for a 5-star – or<br />

maximum – overall rating.<br />

Key Advantages<br />

• Precision. <strong>IEE</strong>’s <strong>SBR</strong> sensor mat is available in different layouts depending on the<br />

detection accuracy needed to differentiate between people and objects.<br />

• Easy seat integration. The design of our technology is highly flexible, making it easy to<br />

insert the mat into either the A or B surface of the vehicle seat.<br />

• Cost-efficiency. Our development cycles are short and our replacement procedures<br />

simple. There is no need for any initial calibration or recalibration during the entire<br />

lifetime of the sensor mat.<br />

• Added value. The sensor mat can be used for other occupant-related comfort functions,<br />

including seat heater switches.<br />

• Reliability. The sensor maintains robust performance regardless of temperature, humidity<br />

and age. It is not affected by seat adjustments, repositioning or shocks and vibrations.<br />

• Experience. <strong>IEE</strong> has gathered unparalleled car seat know-how due to long-standing<br />

partnerships with seat manufacturers worldwide. Our <strong>SBR</strong>s have been installed in over<br />

50 million vehicles across the globe.<br />


Reliable Technology<br />

About Us<br />

The <strong>IEE</strong> <strong>Seat</strong> <strong>Belt</strong> <strong>Reminder</strong> consists of a sensor mat inserted in the vehicle<br />

seat and is based on a technology which uses variable resistance to measure<br />

pressure applied to sensor cells.<br />

The mat itself is composed of two sandwiched carrier sheets held together<br />

by an adhesive. Increased pressure on the sensor mat causes an electrical<br />

resistance change, which tells the system that the seat is occupied. The seat<br />

belt reminder system is automatically activated and visually and/or audibly<br />

reminds the occupant to buckle up.<br />

The key advantage of using force sensing cells is their extreme efficiency.<br />

The technology is also designed for thin applications, which is crucial for a<br />

sensor mat that needs to be flexible in order to be inserted into the vehicle<br />

seat.<br />

<strong>IEE</strong> is an innovative developer of specialized sensing systems. Our sensing technologies<br />

are dedicated to the following markets: Transportation & Automotive, Public & Commercial<br />

Infrastructure, Consumer and Medical & Healthcare.<br />

<strong>IEE</strong> was founded in 1989 and is headquartered in Luxembourg. We operate in Europe, the<br />

U.S. and Asia, and employ 1,600 people worldwide. More than 10% of our workforce is<br />

dedicated to Research and Development.<br />
