Apparatus (10) for helping to protect an occupant of a vehicle (12) which has a side structure (16) and a roof (18) comprises an inflatable vehicle occupant protection device (14). The inflatable vehicle occupant protection device (14) is inflatable away from the vehicle roof (18) into a position between the side structure (16) of the vehicle (12) and a vehicle occupant. An inflation fluid source (24) provides inflation fluid for inflating the inflatable vehicle occupant protection device (14). A plurality of arc-shaped connections (60) define a plurality of arc-shaped chambers (70) of the inflatable vehicle occupant protection device. Each of the arc-shaped chambers (70) includes an arc-shaped upper side wall defined by one of the arc-shaped connections (60) and an arc-shaped lower side wall defined by another of the arc-shaped connections. The arc-shaped chambers (70) are positioned vertically adjacent to each other such that the lower side wall of one of the arc-shaped chambers forms the upper side wall of an adjacent arc-shaped chamber.
