Vehicle occupant protective system

摘要

The protective system is for an automotive vehicle having a driver's seat and an assistant driver's seat. A magnitude of detected decoloration 1 is compared with first (VTH1) and second (VTH2) threshold values, the second threshold value being greater than the first threshold value. If the magnitude of detected deceleration exceeds the second threshold value, both of a first air bag provided for the driver's seat and a second air bag provided for the assistant driver's seat are caused to be inflated even when the assistant driver's seat is not occupied, whereas if the magnitude of detected deceleration exceeds the first threshold value but does not exceed the second threshold value, the first air bag for the driver's seat alone is caused to be inflated when the assistant driver's seat is not occupied.
