An airbag system for restraining a lower body of a vehicle occupant during a collision event and a method for deploying the same are disclosed. The airbag system includes a panel and a restraining airbag. The panel defines a support surface that is adapted to be deployed from a first configuration to a second configuration responsive to the collision event. In the first configuration, the panel forms part of an instrument panel of a vehicle and, in the second configuration, the panel is at least partially separated from the instrument panel of the vehicle. The restraining airbag is adapted to be deployed adjacent to the support surface of the panel between the support surface and the lower body of the vehicle occupant responsive to the collision event.
