    Abstract: Valve for an airbag system for a motor vehicle and airbag system for a motor vehicle
    The invention relates to a valve for an airbag system for a motor vehicle, having:



    a housing (20) which extends along a longitudinal axis (21) and surrounds a cavity (22) having a taper (17) and surrounds a control chamber;
    an electrically switchable pilot valve (15) which selectively seals or releases a pilot opening (6) of the control chamber (5);
    a piston (3) which is arranged in the cavity (22) and can be displaced along the longitudinal axis (21) relative to the housing (20);
    an equalization line (4, 18) which connects an inlet (1) of the valve (100) to the control chamber (5) for fluid communication, wherein:
    a sealing seat (2) is formed at the taper (17) in order to block a gas flow from the inlet (1) to an outlet (14) of the valve (100) in a closed position, in which the piston (3) is in contact with the sealing seat (2), and to release said gas flow in further positions;
    the control chamber (5) is arranged on a first side (24) of the piston (3) facing away from the sealing seat (2); and
    the piston (3) has a first diameter on a side (23) facing the sealing seat (2) and a second diameter (26) on the first side (24), the first diameter (25) being less than the second diameter (26).

    Abstract: Airbag cushion assemblies for aspirating ambient air to enhance inflation. Some embodiments may comprise an inflation module comprising an inflator and a plurality of high-velocity nozzles fluidly coupled with the inflator and configured to deliver inflation gas from the inflator into an airbag cushion. A housing coupled to the airbag cushion, may comprise an aspiration inlet configured to allow for receipt of ambient air into the airbag cushion during inflation of the airbag cushion. The plurality of high-velocity nozzles may be configured to, upon actuation of the inflator, draw ambient air into the airbag cushion along with the inflation gas from the inflator. In some embodiments, a valve assembly may be provided that is configured to open upon actuation of the inflator and to close following inflation of the airbag cushion to prevent air and inflation gas from exiting through the aspiration inlet.

    Abstract: A side airbag system for a vehicle has a primary airbag and a secondary airbag at least partially surrounding the primary airbag. The primary airbag comprises at least one primary vent venting into the secondary airbag and the secondary airbag comprises at least one secondary vent. The primary airbag is inflated by an inflator and the secondary airbag is inflated by gases leaving the primary airbag through the primary vent. The secondary airbag has a panel overlying the primary vent, and inflation of the primary airbag urges the vent and panel in an outboard direction against outboard vehicle structure to restrict flow through the vent. The inflation rates of the primary and secondary airbags are thereby controlled such that the primary airbag protects a vehicle occupant against impacts with a localized load profile and the primary and secondary airbags together protect the occupant against impacts with a distributed load profile.

    Abstract: An air bag packaging arrangement includes an air bag and an air valve. The air bag includes first and second cell overlapped layers to form an air chamber and a valve opening. The air valve includes first and second sealing films overlapped between the first and second cell layers, and a check sealing film overlapped between proximal portions of the first and second sealing films to define an air inflating channel between the first sealing film and the check sealing film, and a backflow prevention channel between the check sealing film and the second sealing film. In case of air leakage, the air is guided to flow to the backflow prevention channel for creating a supplemental air pressure to further seal and close the air inflating channel, so as to make up a deficient sealing effect of the first and second sealing films.

    Abstract: In a front passenger seat airbag apparatus, a partition wall portion is disposed in an airbag to partition the inside of the airbag into a front chamber and a rear chamber. The entire outer circumferential edge of the partition wall portion is jointed with an outer circumferential wall of the airbag, and the partition wall portion includes a communication portion for communication between the front chamber and the rear chamber. The communication portion includes a flow rate control mechanism that controls a flow rate of inflation gas flowing from the front chamber into the rear chamber by increasing or decreasing an opening area of the communication portion. The flow rate control mechanism is configured to suppress flow of the inflation gas into the rear chamber via the communication portion at initial inflation of the airbag in such a manner that the front chamber is inflated, and is configured to open the communication portion in such a manner that the inflation gas flows into the rear chamber by an internal pressure of the front chamber.
