Abstract: A buckle pretensioner system includes a substantially L-shaped rail for guiding a buckle body of a buckle from a position where the buckle body engages with a tongue plate to a position corresponding to a lumbar region of a vehicle occupant. When a vehicle disposed with the buckle pretensioner system undergoes a sudden deceleration, a piston inside a cylinder is moved in a frontward direction of the vehicle by gas generated by the actuation of a gas generator, a buckle stay is pulled by a wire coupled to the piston, and the buckle stay is moved along the shape of the rail. As a result, the buckle body supported by the buckle stay pivots from the position where the buckle body engages with the tongue plate to a vehicle occupant restraining position of a webbing belt, and then is pulled to the lumbar region-corresponding position.

Abstract: In a webbing take-up device, when the release of a webbing belt is detected from the signal of a buckle switch, a motor starts driving, the webbing belt is taken up, and a computing circuit increases a voltage Eb in accordance with an integrated time after the signal is switched. In this state, a lock current flows due to an output shaft of the motor being stopped, and when the power to the motor is cut off by increasing the lock current, the values of voltages El and Ed respectively corresponding to the integrated time in which the lock current is powered and the integrated time in which the power to the motor is cut off are subtracted from the value of the voltage Eb, and the motor is driven until the computing result reaches a predetermined value.
