1. An occupant protection device that protects an occupant boarding on a vehicle, the occupant protection device comprising:
a base portion fixed to the vehicle;
an operation portion connected to the base portion and configured to move back and forth between a first position serving as an initial position and a second position used to suppress movement of the occupant when inertial force acts on the occupant, wherein the operation portion comprises an airbag attached at a position that is configured to face the occupant in a case of having moved to the second position;
a gas generator configured to supply gas to the airbag; and
a control unit configured to activate the gas generator to supply gas to the airbag to perform movement control to move the operation portion from the first position to the second position, wherein the operation portion is movable repeatedly from the first position to the second position through the movement control by returning to the first position after having moved from the first position to the second position,
wherein the occupant protection device further includes a buffering means configured to buffer a collision impact on the occupant against the operation portion when the operation portion moves to the second position; and
wherein in a case where the control unit determines a distance between the operation portion at the second position and the occupant is less than a predetermined distance, the control unit does not activate the gas generator at the time of performing the movement control.
