Vehicle occupant safety apparatus

摘要

A vehicle occupant safety apparatus (10) for helping to protect an occupant of a vehicle (12) having a roof (46) and a side structure (40) includes a first vehicle occupant protection device (20). The first protection device (20) is inflatable into a position between the side of the occupant's head and the vehicle side structure (40). A first inflation fluid source (14) directs inflation fluid into the first inflatable device to inflate the first inflatable device. A second vehicle occupant protection device (22) is inflatable into a position between the top of the occupant's head and the vehicle roof (46). A second inflation fluid source (16) is actuatable independently of the first inflation fluid source for directing inflation fluid into the second inflatable device to inflate the second inflatable device. Control means (30, 32) is responsive to at least one sensed vehicle condition for selectively actuating the second inflation fluid source (16) at a predetermined period of time after actuation of the first inflation fluid source (14).
