Control system for occupant restraint system

A control system for an occupant restraint system on a vehicle, comprising:

• means for detecting a deceleration of the vehicle;
• means for initiating integration of the deceleration to obtain an integrated value when the deceleration exceeds a predetermined first threshold value;
• timing means for determining a time difference between a first point of time at which integration of the deceleration is initiated to a second point of time at which the integrated value of the deceleration exceeds a second threshold value;
• means for determining an operation timing of the occupant restraint system in accordance with the time difference determined by said timing means;
• means for deciding necessity of operation of the occupant restraint system in accordance with the deceleration detected by said deceleration detecting means;
• and
• means for operating the occupant restraint system at the operation timing determined by said operation timing determining means in response to the necessity of operation decided by said necessity deciding means.
