An apparatus (10) for helping to protect an occupant of a vehicle (12) that has a side structure (16) and a roof (18) includes an inflatable vehicle occupant protection device (14) inflatable away from the vehicle roof (18) into a position between the side structure (16) of the vehicle (12) and a vehicle occupant. The protection device (14) includes an inflatable main portion (62) having at least one inflatable primary chamber (110) and an inflatable secondary chamber (112). An inflation fluid source (30) is actuatable to provide inflation fluid for inflating the protection device (14). The inflation fluid source (30) when actuated directs inflation fluid into the main portion (62) to inflate the main portion (62). Inflation fluid inlets (152) of the primary chambers (110) direct inflation fluid from the inflation fluid source (30) into the primary chambers (110). Inflation fluid outlets (154, 156) of the primary chambers (110) direct inflation fluid from the primary chambers (110) into the secondary chamber (112) to inflate the secondary chamber (112). |
