A rear vehicle seat airbag module configured to be mounted to a portion of a seat back of a front vehicle seat comprising:

• an inflator;
• an inflatable cushion comprising a lower portion, an upper portion and an external tether connecting the lower portion and the upper portion, wherein
• the inflator provides inflation gas to the inflatable cushion,
• the inflatable cushion is configured to deploy forward of an occupant seated in the rear vehicle seat such that the occupant loads the upper portion and the lower portion of the inflatable cushion during a frontal collision of a vehicle, and
• the external tether is configured to control a trajectory of the deployment of the inflatable cushion by restraining the upper portion from deploying away from the lower portion so that when the cushion is inflated the cushion is configured in a curved shape wherein the upper portion is located above the lower portion.
