Abstract
The tethered airbag system includes an inflatable cushion and an extensible tether. The extensible tether includes an extensible region and is attached to both the inflatable cushion and to a point within a vehicle. For instance, the tether may be attached to the roof of the vehicle. When in use, the inflatable cushion deploys to a location immediately in front of an occupant of the vehicle. Following deployment of the cushion, when a sufficient force is applied to the inflatable cushion, the extensible region is released so that the extensible tether may extend to its full length and the inflatable cushion may extend further away from the point where the tether is attached to the vehicle.
