An inflatable curtain module is disclosed, where the inflatable curtain module has an inflator, and an inflatable curtain. The inflator may have a biaxial flow providing a gas input into two separate inflatable cushions. The cushions may be different sizes or volumes. Alternatively, other inflatable curtain modules may incorporate multiple inflators and multiple cushions to create an inflatable curtain module. The multiple inflators can be employed to provide two gas inputs into a single inflatable cushion. An inflatable curtain module may also be created from a number of generically sized cushions and inflators that are assembled into an inflatable curtain module for a wide range of vehicles.
