Disclosed are embodiments of apparatus, methods, and systems for cutting one or more tethers connected with an airbag cushion and simultaneously, or sequentially, closing one or more vent openings. In one embodiment, an airbag module is provided that includes a tether opening and at least one vent opening. The tether may extend through the tether opening adjacent to a cutter. The cutter may be configured to cut the tether upon deployment of an actuator. A vent door configured to block the vent opening(s) upon deployment of the actuator may also be provided. This embodiment may therefore provided for simultaneous, or sequential, cutting of the tether and closing of the vent opening(s) with a single actuator.
