Abstract

A control assembly for a passenger protection system of a vehicle which is tripped upon the occurrence of a side impact traffic accident. The control assembly has at least one detector adapted to detect a pressure rise in a hollow body. The at least one detector is mounted in a largely enclosed side portion on the side of the vehicle body defining a hollow body such as a door. A control unit is connected to and receives signals from the at least one detector. The control unit evaluates a sudden and largely adiabatic air pressure rise detected by the detector upon a side impact collision and determines whether to actuate a passenger protection system such as an air bag.
