Inflatable curtain airbags can be used to mitigate the likelihood of an occupant being ejected from a vehicle through a side window. Inflatable curtain airbags are typically tethered to a vehicle structure on a car-forward side, but may not be tethered to a vehicle structure on their car-rearward side. Increased friction between the car-rearward side of the airbag and an adjacent vehicle structure can be used to help the airbag say in place, and thereby decrease the likelihood of an occupant passing the airbag and being ejected from the vehicle.
