Airbag assemblies and venting assemblies are disclosed. An airbag assembly (100) includes an airbag cushion (110) and a venting assembly (120) including a vent (130, 140), one or more shear tethers (160) , and a peel tether (150). The shear tether(s) are configured to be drawn to a taut state by expansion of the airbag cushion to configure the vent in a first venting state. The shear tether(s) are releasably coupled to the peel tether. The releasable coupling is configured to keep the shear tether(s) releasably coupled to the peel tether. The peel tether is configured to transition from a slack state to a taut state as the airbag cushion continues to expand. When drawn taut, the peel tether produces a peel force transverse to the shear force. The peel force causes the releasable coupling to release and the peel tether to uncouple from the shear tether(s), to transition the vent to a second state.
