Process for controlling occupant safety devices corresponding to the requirements
First Claim
1. A process for controlling occupant safety devices taking into account an occupant'"'"'s expected movement relative to a vehicle, comprisingdetermining an initial expected acceleration profile for the vehicle during an accident;
- determining an occupant'"'"'s individual parameters;
measuring an actual acceleration profile of the vehicle which occurs up to a respective point in time during an accident;
Generating a modified expected acceleration profile of the vehicle, based on a comparison of the initial expected acceleration profile and measured actual acceleration data;
determining an expected movement of a vehicle occupant relative to the vehicle based on the modified expected acceleration profile of the vehicle and on the occupant'"'"'s individual parameters; and
controlling operating parameters of said safety devices based on the expected movement of the vehicle occupant.

Abstract
A process is provided for controlling occupant safety devices corresponding to specific requirements while taking into account the occupant'"'"'s expected movement relative to the vehicle. The expected movement of the vehicle occupant is determined on the basis of the expected acceleration profile of the vehicle during the accident and on the basis of the actual parameters of the individual vehicle occupant. The expected acceleration profile of the vehicle is extrapolated on the basis of the acceleration profile which took place up to the respective point in time.
