A separator is disposed between adjacent chambers. The chambers may be inflated to different pressures and in various sequences.
Claims20
A side impact air bag for a motor vehicle, the side impact air bag having a stored condition in which the side impact air bag is located within a vehicle seat and an inflated condition in which the side impact air bag is located between a seat occupant and an interior vehicle surface, the side impact air bag comprising:
- a first chamber having an inlet for receiving an inflation gas from an inflation gas source;
- a second chamber disposed adjacent to the first chamber;
- and
- a first separator disposed between the first and second chambers, the first separator adapted to communicate the inflation gas from the first chamber to the second chamber;
- wherein the first chamber is disposed proximate a shoulder of the seat occupant and the second chamber is disposed proximate a thorax of the seat occupant when the side impact air bag is in the inflated condition.
A side impact air bag for a motor vehicle, the side impact air bag having a stored condition in which the side impact air bag is located within a vehicle seat and an inflated condition in which the side impact air bag is located between a seat occupant and an interior vehicle surface, the side impact air bag comprising:
- a first chamber having a first inlet for receiving an inflation gas from an inflation gas source;
- a second chamber disposed adjacent to the first chamber;
- a third chamber disposed adjacent to the second chamber and opposite the first chamber, the third chamber having a second inlet for receiving the inflation gas from the inflation gas source;
- a first separator disposed between the first and second chambers;
- and
- a second separator disposed between the second and third chambers;
- wherein the first chamber is disposed proximate a shoulder of the seat occupant, the second chamber is disposed proximate a thorax of the seat occupant, and the third chamber is disposed proximate a pelvis of the seat occupant when the side impact air bag is in the inflated condition.
A side impact air bag for a motor vehicle, the side impact air bag having a stored condition in which the side impact air bag is located within a vehicle seat and an inflated condition in which the side impact air bag is located between a seat occupant and an interior surface of a vehicle door, the side impact air bag comprising:
- a first chamber having an inlet for receiving an inflation gas from an inflation gas source;
- a second chamber disposed adjacent to the first chamber;
- and
- a separator disposed between the first and second chambers, the separator being adapted to communicate the inflation gas from the first chamber to the second chamber;
- wherein the first chamber is disposed below the second chamber and the second chamber is inflated to a higher pressure than the first chamber when the side impact air bag is in the inflated condition.
