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.
