The TOR-system is based on a sensor combination using 2 different physical properties independent of each other, in order to realise an occupant detection system. Purpose of the system is to fulfill the NHTSA FMVSS 208 regulation for an automatic suppression system. It includes an additional feature for an automatic suppression zone of 15 - 20 cm around the airbag cover. The system consists of a force sensitive matrix-mat under the seat-cover and an EFD-system (Electrical Field Detection), with sensors in the seatplain, the backrest and the dashboard. Additionally, two sensors installed at the seat-frame provide the information on seat-position and backrest-angle.
