Abstract
In at least one implementation, a variable volume airbag includes an inflatable cushion and a tether coupled to the cushion. The inflatable cushion defines an inner volume in which a gas is received to inflate the cushion longitudinally and laterally within a passenger compartment of a vehicle, and has laterally opposed side surfaces defining part of the inner volume of the cushion. The tether is coupled to each of the side surfaces of the cushion and has a first state wherein the tether limits lateral separation of the side surfaces and a second state wherein increased separation of the side surfaces is permitted as compared to the first state.
