1. An airbag module, comprising:
- an inflatable airbag cushion having a cushion membrane;
at least one laced vent comprising opposing vent sides around a vent aperture in the membrane of the inflatable airbag cushion, wherein the vent aperture is defined by edges of the sides; and
a cord coupled to the cushion membrane of the inflatable airbag cushion and having a laced portion which extends across the vent aperture between the opposing vent sides in a configuration such that upon deployment of the inflatable airbag cushion with obstruction, the cord does not fully extend and the vent remains open, and upon deployment of the inflatable airbag cushion without obstruction, the cord extends and at least partially closes the vent.

17. An airbag module, comprising:
-
an inflatable airbag cushion having a cushion membrane; a first laced vent comprising first opposing vent sides around a first vent aperture in the membrane of the inflatable airbag cushion, wherein the first vent aperture is defined by edges of the first vent sides, a second laced vent comprising second opposing vent sides around a second vent aperture in the membrane of the inflatable airbag cushion, wherein the second vent aperture is defined by edges of the second vent sides; and at least one cord coupled to the cushion membrane of the inflatable airbag cushion and having a first laced portion and a second laced portion, wherein the first laced portion extends across the first vent aperture of the inflatable airbag cushion between the opposing first vent sides and wherein the second laced portion extends across the second vent aperture of the inflatable airbag cushion between the opposing second vent sides such that, upon deployment of the inflatable airbag cushion with obstruction, the cord does not fully extend and the first laced vent and the second laced vent remain open, and upon deployment of the inflatable airbag cushion without obstruction, the cord extends and at least partially closes the first laced vent and the second laced vent. - View Dependent Claims (18, 19, 20, 21, 22)

23. An airbag module, comprising:
-
an inflatable airbag cushion having a cushion membrane with a throat for receiving inflation gas upon deployment; a first laced vent comprising first opposing vent sides around a first vent aperture in the membrane of the inflatable airbag cushion, wherein the first vent aperture is defined by edges of the first vent sides, a second laced vent comprising second opposing vent sides around a second vent aperture in the membrane of the inflatable airbag cushion, wherein the second vent aperture is defined by edges of the second vent sides; and at least one cord coupled to the cushion membrane of the inflatable airbag cushion and having a first laced portion and a second laced portion, wherein the first laced portion extends across the first vent aperture of the inflatable airbag cushion between the opposing first vent sides and wherein the second laced portion extends across the second vent aperture of the inflatable airbag cushion between the opposing second vent sides such that, upon deployment of the inflatable airbag cushion with obstruction, the cord does not fully extend and the first laced vent and the second laced vent remain open, and upon deployment of the inflatable airbag cushion without obstruction, the cord extends and at least partially closes the first laced vent and the second laced vent, and wherein the cord is coupled to the cushion membrane at a location such that upon deployment the distance from the location to the throat is greater than the distance from the throat to at least one of the laced vents.
