A passenger protection system to be mounted to a vehicle includes an airbag having a first airbag section for constraining a driving passenger by being deployed and inflated between the driving passenger and a steering wheel, and a second airbag section that is deployed and inflated on the front side of the vehicle with respect to the steering wheel. Pressure from the first airbag section is received by the steering wheel, and pressure from the second airbag section is received by a front windshield glass and an interior panel positioned on the front side of the vehicle with respect to the steering wheel when the airbag is deployed and inflated. The system provides improved protection for a driving passenger using an airbag in the event of a vehicle accident.
