Abstract
Embodiments herein relate to a motor vehicle safety arrangement and method for positioning an occupant properly on a vehicle seat and restraining the occupant thus positioned in preparation of the vehicle potentially being subject to a rear-end collision. A safety belt is associated with the vehicle seat and an electric reversible safety belt retractor is associated with the safety belt. A rearward-looking detection system detects and classifies the collision risk for an approaching object. At least one sensor monitors one or more vehicle parameters. A control unit determines a driving state as critical or non-critical from the monitored vehicle parameters. The control unit controls the electric reversible safety belt retractor to apply a predetermined pullback force on the safety belt in response to the collision risk for an approaching object being classified as high within a predetermined time of an indicated critical driving state.
