Abstract
An occupant protection device for a vehicle includes a first bag that deploys in front of a vehicle's occupant, a second bag that deploys adjacent to the first bag, and a deployment controller that selects, according to a collision mode, a first deployment mode in which the first bag deploys and the second bag does not deploy and a second deployment mode in which both bags deploy. The first bag includes a first air chamber, a second air chamber that extends from the first air chamber toward the second bag, and a communication flow path that supplies deployment gas from the first air chamber to the second air chamber. The communication flow path includes a supply restriction unit that restricts supply of the deployment gas from the first air chamber to the second air chamber in response to interference between the second air chamber and the second bag.
