Abstract

A safety system for safety belts in a vehicle containing a variable power limiter with the objective to regulate the chest belt loading on the occupant in a collision. The power limiter is located in conjunction to the belt reel of the chest part of the safety belt, containing of an electric controlled unit that is regulated by a number of sensors and a control unit located in the vehicle. In a frontal collision will the safety system regulate the loading acting on the occupants neck and chest. The system is also designed to efficiently distribute the decelerating forces generated by the occupants kinetic energy between the safety belt, airbag and vehicle seat.
