SYSTEM AND METHOD EMPLOYING CAR SEAT BELT TO ENHANCE SAFETY OF OCCUPANT

An object of the present invention is to provide a system for improving safety of an occupant by a vehicle seat belt, which can provide adaptive protection for an occupant in different seat positions and different sitting postures. Another object of the present invention is to provide a method for improving safety of an occupant by a vehicle seat belt, and still another object of the present invention is to provide a computer-readable medium. The a system for improving safety of an occupant by a vehicle seat belt includes an in-vehicle observation system, an active seat belt system, and an integrated safety domain control unit. The integrated safety domain control unit formulates a vehicle seat belt protection strategy based on received data from the in-vehicle observation system, and a slack state of an active retractor and a positional state of an active lift buckle in the active seat belt system, to implement selective tightening or loosening of the active retractor and/or selective lifting or lowering of the active lift buckle.
