Abstract

The present invention relates to a method for controlling a reversible seat belt pretensioner in a motor vehicle, comprising the steps of detecting the speed and the steering angle of the vehicle, calculating an expected turning rate of the vehicle about its vertical axis from the speed and the steering angle and calculating an upper and a lower turning rate limiting value using the expected turning rate, detecting the actual turning rate of the vehicle about its vertical axis and activating the seat belt pretensioner of the vehicle if the actual turning rate of the vehicle is greater than the upper turning rate limiting value or is less than the lower turning rate limiting value. The present invention also relates to a safety arrangement for implementing the method according to the invention.
