Abstract
An apparatus for helping to protect a vehicle occupant includes an airbag having primary and secondary chambers fluidly connected by a first passive vent and an active vent having an open condition and a closed condition. The primary chamber has a stored condition and a deployed condition to cover a portion of the vehicle. An interior panel divides the primary chamber into upper and lower inflatable volumes and includes a second passive vent fluidly connecting the upper and lower inflatable volumes. The secondary chamber has a stored condition and a deployed condition to cover portions of the vehicle left uncovered by the primary chamber. An inflator is actuatable to provide inflation fluid to the primary chamber. The active vent is controllable to prevent fluid communication between the primary and secondary chambers in response to occupant penetration into the primary chamber and controllable to allow fluid communication between the primary and secondary chambers in response to occupant penetration into the secondary chamber. The second passive vent automatically closes to prevent fluid flow from the lower inflatable volume to the upper inflatable volume in response to occupant penetration into the secondary chamber.
