The airbag (70) has a stored condition within the roof (32) and is inflatable to a deployed condition extending into the cabin (40) and aligned with the seat (50). The airbag (70) includes a first portion (94) defining a first chamber (100) and a second portion (104) defining a second chamber (110). The first portion (94) is connected to the vehicle (20) and includes a vent (106).
