OCCUPANT PROTECTION DEVICE

An occupant protection device for a vehicle includes a collision detector, a main airbag, a belt airbag, a belt controller, a distance detector, and an airbag controller. The collision detector detects a collision of the vehicle. In response to the collision detector detecting the collision, the main airbag deploys from a storage position toward an occupant seated on a seat of the vehicle. The belt airbag is stored in a seatbelt. The belt controller controls winding of the seatbelt, extraction of the seatbelt, and prohibition of the extraction of the seatbelt. The distance detector detects a distance from the storage position to the occupant. When the collision detector detects the collision of the vehicle and the detected distance is equal to or greater than a predetermined distance, the airbag controller deploys the belt airbag from within the seatbelt without causing the belt controller to prohibit the extraction of the seatbelt.
