Abstract
A vehicle occupant protection device includes: a seat belt device having a selectable force limiter that is configured to switch a force limiter load from a high load to a low load; an airbag device that deploys an airbag in front of the occupant; a movement direction detector that detects a direction in which a head region of the occupant will move relative to the vehicle at the time of frontal collision; an initial position detector that detects a position of the head region prior to the movement; and a control unit that makes a determination whether or not the head region will move outside of an area of protection by the airbag based on detection results of the movement direction detector and the initial position detector and, in a case in which the determination is affirmative, maintains the high load of the force limiter load.
