Abstract
A seat belt system includes a retractor and a seat belt. The retractor includes a motor that drives a pressure rod into a seat belt such that the seat belt is nipped between the pressure rod and belt receiving portions. The driving force of the motor that controls the movement of the pressure rod is set based on the situation at the time of a collision. Thus, the load limit to be exerted on the seat belt is set flexibly and widely according to the situation in an emergency. Further, the motor and the pressure piston rod can be activated repeatedly and, therefore, can be reused.
