First Claim
Patent Images
1. A side curtain airbag, comprising:
- a rear chamber,a front chamber;
a secondary chamber affixed to said front chamber;
a baffle vent between the front chamber and the secondary chamber; and
tear stitching configured to tear at selected inflation pressure, and permanent stitching, each stitching connecting the secondary chamber to an inboard panel of the front chamber on opposing sides of the baffle vent such that, upon tearing of the tear stitching, the secondary chamber occupies a gap between a driver airbag and the side curtain airbag.

11. A method of deploying a vehicle side airbag that includes a front chamber, a rear chamber, and a secondary chamber affixed to the front chamber, in an oblique crash, the method comprising:
-
receiving data from at least one impact sensor indicating an oblique impact; determining a severity of the oblique impact; and if the severity exceeds a predetermined threshold, sending a first instruction to a triggering mechanism to cause the front chamber, the rear chamber, and the secondary chamber to inflate, but if the severity does not exceed the predetermined threshold, sending a second instruction to the triggering mechanism to cause only the front chamber and the rear chamber to inflate. - View Dependent Claims (12, 13, 14, 15)

16. A controller comprising a processor and a memory, the memory storing instructions executable by the processor, including instructions to:
-
identify the occurrence of an oblique impact from data received from at least one impact sensor; determine whether the data indicates that a severity of the oblique impact exceeds a predetermined threshold; and if the severity exceeds the predetermined threshold, send a first instruction to a triggering mechanism to cause a front chamber, a rear chamber, and a secondary chamber of a side airbag to inflate, but if the severity does not exceed the predetermined threshold, send a second instruction to the triggering mechanism to cause only the front chamber and the rear chamber to inflate. - View Dependent Claims (17, 18, 19, 20)
