Abstract
Airbag assemblies and vents are disclosed. An airbag assembly includes an airbag cushion and a vent assembly including a vent, one or more sheer tethers, and a peel tether. The sheer 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 sheer tether(s) are releasably coupled to the peel tether. The releasable coupling is configured to maintain the sheer 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. The peel tether drawn taut produces a peel force transverse to the sheer force. The peel force causes the releasable coupling to release and the peel tether to uncouple from the sheer tether(s), to transition the vent to a second state.
