METHOD FOR CONTROLLING A BELT PRETENSIONER AND SAFETY ARRANGMENT COMPRISING A BELT PRETENSIONER
摘要
The method involves detecting speed and steering angle of a motor vehicle, and evaluating an estimated rotational rate (20) of the vehicle at a vertical axis from the speed and the angle. An actual rotational rate (18) of the vehicle is detected at the vertical axis. A seal-belt-pretensioner is activated when the actual rotational rate (18) of the vehicle is greater than an upper threshold value or smaller than a lower threshold value. An independent claim is also included for a safety arrangement for a motor vehicle with a safety belt and a reversible seat-belt-pretensioner.
