IEE Introduces Innovative Seat-Belt Warning SystemLUXEMBOURG, Oct. 24 IEE s.ar.l. -- the world leader in automotive occupant sensing systems -- recently introduced its innovative seat-belt warning system designed to detect the presence of a car occupant over 15 kg in the front passenger seat and/or on the rear bench of the car. The IEE seat belt warning system connected to a seat-belt buckle triggers a warning light reminding the seat occupant to fasten his or seat belts. In addition, the system increases safety, especially children's safety, by warning when a seat occupant undoes the seat-belt during the ride. The IEE sensor consists of a sensor mat composed of two sandwiched carrier sheets held together by a connective adhesive. Increased pressure on the sensors in the mat, electrically connected in parallel, causes a decrease in electrical resistance which informs the system if the seat is occupied and automatically activates a seat-belt warning. The function described above is one potential application among many of the new sensor system. Easily added are sensor-activated controls governing air-conditioning, seat-heaters, electrical headrests, interior lighting, car audio and seat-position memory.
