US Patent 11603014 Occupant protection device

An occupant protection device for a vehicle includes: a collision predictor configured to predict a collision of the vehicle; a main airbag configured to deploy toward an occupant from a front of the vehicle when the collision predictor predicts a collision of the vehicle; an occupant center-of-gravity detecting device configured to detect a position of a center of gravity of the occupant; an armrest moving device configured to move an armrest; and a deployment controller configured to cause, when the collision predictor predicts a collision of the vehicle, the armrest moving device to move the armrest upward to guide the center of gravity of the occupant into a proper range on the basis of the position of the center of gravity of the occupant detected by the occupant center-of-gravity detecting device, subsequently cause the armrest moving device to remove the armrest, and thereafter, cause the main airbag to deploy.
