Dual chamber airbag with asymmetrically tunable parameters and method of manufacturing the same

A vehicle airbag assembly, comprising:

• an airbag comprising a first chamber and a second chamber;
• at least one internal tether coupled to the second chamber for restricting an inflated depth of the second chamber;
• a first internal vent permitting gas entry into the first chamber;
• a second internal vent permitting gas entry into the second chamber;
• a gas inlet positioned at an external wall of the airbag for inflating the airbag;
• and
• an internal passageway connecting the gas inlet to the first internal vent and the second internal vent,
• wherein the first chamber has an unrestricted depth and a volume that is larger than a volume of the second chamber in an inflated state of the airbag.

A method of manufacturing a vehicle airbag, comprising:

• forming a first airbag chamber having a first width selected according to a vehicle outboard configuration;
• forming a second airbag chamber having a second width selected according to a vehicle inboard configuration;
• forming a first vent for permitting a first gas flow into the first airbag chamber;
• forming a second vent for permitting a second gas flow into the second airbag chamber;
• and
• determining a first height for the first vent and a second height for the second vent such that the first gas flow is greater than the second gas flow.
