    摘要： An automotive passenger restraint and protection apparatus for an automotive vehicle has a seatbelt and operates to restrain an occupant of the automotive vehicle by the seatbelt to protect the occupant. An electric retractor has a DC motor for retracting and protracting the seatbelt. An MPU controls the DC motor. Protraction of the seatbelt by the occupant is detected. When the protraction of said belt is detected, the MPU controls the DC motor so as to protract the seatbelt. A seatbelt protraction and retraction amount-detecting device calculates an amount of protraction or retraction of the seatbelt, based upon at least one of a number of times pulsating components of detected terminal voltage across the DC motor rises above a first predetermined value from a value below a first predetermined value, a number of times the pulsating components drops below a second predetermined value from a value above the second predetermined value, a frequency component obtained by frequency analysis of the pulsating components, and results of time integration of the detected terminal voltage, and a detected rotational direction of the motor.

    摘要： An automotive passenger restraint and protection apparatus includes an electric retractor having a motor for retracting and protracting a seatbealt. The apparatus also includes an airbag driving device, a pretensioner, a speed detecting device, and a controller. The controller controls at least one of the actuation time or expansion pressure of an airbag by the airbag driving device, actuation time of the pretensioner, a force of the pretensioner for retracting the seatbelt, and a force of the seatbelt driving device for retracting the seatbelt, based upon the speed of protraction of the seatbelt. The controller controls the airbag driving device to shorten the actuation time of the airbag when the speed of protraction of the seatbelt is greater than a predetermined value, and prolongs the actuation time of the airbag when the detected speed of protraction of the seatbelt is lower than the predetermined value.

    摘要： In a through anchor (10), a webbing sliding contact surface (15) is formed by bending in a curved fashion a lower edge of an opening (14) formed in a metal insert (11) toward a side. The through anchor (10) is covered over portions of the metal insert (11) other than the webbing sliding contact surface (15) with a coating resin (13). Accordingly, it is possible to provide a seat belt assembly that can continue to provide good sliding contact between a webbing guide and webbing, with simple construction.
