Apparatus (10) for helping to protect an occupant of a vehicle (12) that has a side structure (16) and a roof (18) comprises an inflatable protection device (14) and a source (22) of inflation fluid for inflating the device between the side structure (16) a vehicle occupant. The device (14) includes a perimeter (48) at least partially defined by upper and lower edges (50 and 52) and front and rear portions (62 and 64) spaced apart along the upper and lower edges. The device (14) also includes at least one connection (70) within the perimeter (48). The connection (70) helps to define at least one inflatable front chamber (120) located in the front portion (62), at least one inflatable rear chamber (150) located in the rear portion (64) and at least one inflatable middle chamber (100) located between the front and rear chambers. The front chamber (120) and the rear chamber (150) each have an inflation fluid inlet (122 and 152) near the upper edge (50) of the device (14) and an inflation fluid outlet (124 and 154). The middle chamber (100) has at least one inflation fluid inlet (102, 104) near the lower edge (52) and is free from inlets near the upper edge (50) The inflation fluid inlets (122 and 152) direct inflation fluid from the source (22) into the front and rear chambers (120 and 150). The inflation fluid outlets (124 and 154) direct inflation fluid from the front and rear chambers (120 and 150) into the inflation fluid inlet (102, 104) of the middle chamber (100) to inflate the middle chamber.
