Abstract:
1. A seatbelt device for a vehicle, comprising: a belt reel for winding in a belt for restraining a vehicle occupant sitting in a seat; a motor for driving the belt reel; a belt retraction part; an actuator for driving the belt retraction part; a traveling state detector for detecting a traveling state of the vehicle; and a controller for controlling the motor and the actuator, wherein the belt retraction part is designed so as to retract part of the belt in a direction opposite the direction in which the belt is wound up by the belt reel so as to restrain the vehicle occupant, the controller includes a plurality of pre-set control modes for controlling the motor and the actuator in accordance with traveling states to be detected by the traveling state detector and is designed to select and implement one of the control modes corresponding to one of the traveling states actually detected by the traveling state detector, and the control modes include a full drive control mode for drive-controlling both the motor and the actuator, a motor drive control mode for drive-controlling only the motor, and an actuator drive control mode for drive-controlling only the actuator.
