Multi-chambered air bag for a motor vehicle
First Claim
1. An air bag for a motor vehicle, the air bag having a deflated condition in which the air bag is located within an interior vehicle surface and an inflated condition triggered by a vehicle impact event in which the air bag is located between a seat occupant and the interior vehicle surface, the air bag comprising:
- a rear chamber having an inlet for receiving an inflation gas from an inflation gas source;
a front chamber disposed adjacent to and in fluid communication with the rear chamber; and
a separator disposed between the front and rear chambers, the separator adapted to communicate the inflation gas from the rear chamber to the front chamber;
wherein when the air bag is in the inflated condition, the seat occupant initially contacts the rear chamber and then contacts the front chamber when a vehicle seat is displaced by the vehicle impact event.

Abstract
An air bag for a motor vehicle. The air bag includes a rear chamber, a front chamber disposed adjacent to and having a lower pressure than the rear chamber, and a separator disposed between the front and rear chambers that is adapted to communicate an inflation gas from the rear chamber to the front chamber. A seat occupant contacts the rear chamber before contacting the front chamber when a vehicle seat is displaced by a vehicle impact event.

7. 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 rear chamber having an inlet for receiving an inflation gas from an inflation gas source, the rear chamber being disposed proximate the vehicle seat; a front chamber disposed proximate to and in fluid communication with the rear chamber; and a separator disposed between the front and rear chambers, the separator adapted to communicate the inflation gas from the rear chamber to the front chamber; wherein the front chamber is located closer to the front of the vehicle than the rear chamber when the side impact air bag is in the inflated condition. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. 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 seat back of 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 rear chamber having an inlet for receiving an inflation gas from an inflation gas source, the rear chamber being disposed proximate the seat back; a front chamber disposed proximate to and in fluid communication with the rear chamber; and a separator disposed between the front and rear chambers, the separator adapted to communicate the inflation gas from the rear chamber to the front chamber; wherein the rear chamber is inflated to a greater pressure than the front chamber in response to a vehicle impact event and the rear chamber moves away from the seat occupant to permit the front chamber to contact the seat occupant when the vehicle seat is displaced during the vehicle impact event. - View Dependent Claims (17, 18, 19, 20)
