Aspects of the disclosure relate to reducing the likelihood of injury to a passenger in a collision. In one example, a computing device may determine that an impact between a vehicle and an object external to the vehicle is imminent. The computing device may determine a protection range for a vehicle's airbag based on characteristics of the passenger, including the passenger's seating location within the vehicle. An airbag extension system may position an airbag package, including the vehicle's airbag, such that the vehicle's airbag is within the protection range of the passenger's seating location.
