 A control system for an apparatus for protecting a head portion of a vehicle occupant includes: an air bag device having an air bag body for protecting a head portion of a vehicle occupant which air bag body inflates and unfolds between the head portion of the vehicle occupant and a side portion of a vehicle; a pretensioner which, upon operation, takes up slack of a seat belt fastened to the vehicle occupant; a roll angular velocity sensor for detecting a roll rate of the vehicle in order to determine a roll state of the vehicle; and a control circuit which, when a determined roll state is a predetermined roll state, controls operation of the air bag device and operation of the pretensioner such that the pretensioner is operated before operation of the air bag device. Accordingly, a space for unfolding the air bag body of the air bag device is ensured.
