An airbag assembly comprising: an airbag cushion formed of one or more panels that define an inflatable chamber configured to receive inflation gas to inflate the airbag cushion ; a first vent in a first panel of the one or more panels of the airbag cushion , the first vent comprising a first aperture defined through the first panel ; a first loop coupled to an interior surface of the airbag cushion within the inflatable chamber at the first panel of the airbag cushion ; a shear tether , wherein a first end is looped through the first loop , a second end opposite the first end is looped through a second loop , and the shear tether is configured to be drawn taut by expansion of the airbag cushion during inflation; a peel tether releasably coupled to the shear tether at a first end of the peel tether , wherein a second end of the peel tether , opposite the first end , is coupled to a bottom portion of the airbag cushion , and the peel tether is configured to be drawn taut as the airbag cushion continues to expand after the shear tether is drawn taut; and a releasable coupling to releasably couple the first end of the peel tether to the first and second ends of the shear tether, the releasable coupling configured to resist a shear force transverse to the first panel to maintain the shear tether drawn taut, the shear force produced by expansion of the airbag cushion drawing the shear tether taut , the releasable coupling further configured to release in response to a peel force transverse to the shear force, the peel force produced by expansion of the airbag cushion drawing the peel tether taut, so that the first end of the shear tether unloops through the first loop , and the second end of shear tether unloops through the second loop after the releasable coupling is released. an airbag cushion formed of one or more panels that define an inflatable chamber configured to receive inflation gas to inflate the airbag cushion ; a first vent in a first panel of the one or more panels of the airbag cushion , the first vent comprising a first aperture defined through the first panel ; a first loop coupled to an interior surface of the airbag cushion within the inflatable chamber at the first panel of the airbag cushion ; a shear tether , wherein a first end is looped through the first loop , a second end opposite the first end is looped through a second loop , and the shear tether is configured to be drawn taut by expansion of the airbag cushion during inflation; a peel tether releasably coupled to the shear tether at a first end of the peel tether , wherein a second end of the peel tether , opposite the first end , is coupled to a bottom portion of the airbag cushion , and the peel tether is configured to be drawn taut as the airbag cushion continues to expand after the shear tether is drawn taut; and a releasable coupling to releasably couple the first end of the peel tether to the first and second ends of the shear tether, the releasable coupling configured to resist a shear force transverse to the first panel to maintain the shear tether drawn taut, the shear force produced by expansion of the airbag cushion drawing the shear tether taut , the releasable coupling further configured to release in response to a peel force transverse to the shear force, the peel force produced by expansion of the airbag cushion drawing the peel tether taut, so that the first end of the shear tether unloops through the first loop , and the second end of shear tether unloops through the second loop after the releasable coupling is released. <EOS>
