Abstract
An adaptive seat belt system (10) for an automotive vehicle (12). The system (10) includes a seat belt (16) extensible about an occupant (42) of a seat system (14). A seat belt tension sensor (18) is coupled to the seat belt (16) and generates a seat belt tension signal. A seat belt actuator (20) is mechanically coupled to the seat belt (16) and adjusts tension of the seat belt (16). A controller (26) is electrically coupled to the tensioner sensor (18) and the actuator (20). The controller (26) generates a seat belt tension adjustment signal in response to the seat belt tension signal and adjusts tension of the seat belt (16) in response to the seat belt tension adjustment signal. A method for performing the same is also provided.
