Title: Inflatable curtain with tensioning device

Abstract: An apparatus (10) for helping to protect an occupant of a vehicle (12) which has a side structure (16) and a roof (28) comprises a vehicle occupant protection device (14). The vehicle occupant protection device (14) is inflatable away from the vehicle roof (28) into a position along the vehicle side structure (16) between the side structure and a vehicle occupant. An inflator (24) provides inflation fluid for inflating the vehicle occupant protection device (14). A flexible elongated member (54) resists movement of the vehicle occupant protection device (14) away from the vehicle side structure (16) when the vehicle occupant protection device is inflated. A tensioning member (52) is movable a given distance upon inflation of the vehicle occupant protection device (14). The tensioning member (52) retracts a length of the flexible elongated member (54) equal to at least approximately twice the given distance when the tensioning member (52) moves the given distance.
