A passenger safety device in which an airbag is disposed in the roof area of the vehicle, especially in the area of the roof rail of the vehicle, and in which the airbag of the airbag is stowed at least partially rolled up in the passenger safety device. These compounds are inhibitors of RNA-dependent 5 RNA viral replication and are useful as inhibitors of HCV NS5B polymerase, as inhibitors of HCV replication and for treatment of hepatitis C infection in mammals. The upper FBAR is stacked atop the lower FBAR. The second locking member prevents displacement of the first locking member by the plunger to thereby prevent movement of the plunger.
