In recent years, the electronics used in automobiles have become
increasingly sophisticated. In addition to working in combination with
passive safety systems, such as airbags and seat belts, other systems
have been developed to help protect passengers more effectively. These latter systems include devices to alert drivers to the possibility of accidents. One of these new devices, motorized seat belts, acts as a crash-warning system. They have servo-motors to move the seat belt and alert the driver of a potential danger, as well as retract the seat belt to control a passenger’s posture and take up slack if a collision is imminent.
Takata is engaged in developing active safety systems that may help prevent accidents before they occur.
