Bias apparatus for air bag module

An air bag module includes an air bag and an inflator for generating gas to inflate the air bag. The module further includes a bias apparatus including first and second bias flaps being separate and independent from each other. The bias flaps cooperatively define an overlapped portion located atop the air bag prior to inflation such that the inflating air bag is biased when the overlapped portion is restricted and the inflating air bag is unrestrained when the overlapped portion is unrestricted. Preferably, the first and second flaps each have a fixed edge attached to the vehicle and each have a free edge opposite the fixed edge. The free edges of the first and second bias flaps overlap each other to define the overlapped portion.
