Abstract
A roof airbag for vehicles and a control method to deploy the roof airbag are proposed. The roof airbag, which protects occupants by minimizing reduction of internal pressure of the airbag in an accident event in which a vehicle rolls over several times in sequence, includes: a main inflator and sub-inflator which generate gas; and a controller configured to ignite the main inflator to deploy an airbag cushion when a rollover accident of a vehicle occurs, and configured to ignite the sub-inflator to increase internal pressure of the airbag cushion when a secondary accident occurs following the primary rollover accident of the vehicle.
