System Description

The pre-crash seat belt system integrates a control unit and motor in the existing seat belt pre-tensioners for both the driver and front passenger. The motor retracts the seat belt and secures the occupant during non-collision operations. The system integrates various CAN signals from other safety systems to give the driver and passenger a sense of security during various driving conditions. The motor extracts and retracts the seat belts when fastening to reduce effort required.
