Abstract
An automobile vehicle deployable cocoon airbag system includes an airbag cushion having a first side oriented in a vertical configuration in a non-deployed condition and a second side oriented substantially ninety degrees from the first side in the non-deployed condition and adapted to receive an occupant on the second side providing an occupant sleeping position. At least one retracting tether is connected to the first side and the second side and is retracted using a retraction mechanism. The retraction mechanism acts upon receipt of a signal to retract the at least one retracting tether and pull the second side toward the first side thereby enclosing the occupant between the first side and the second side in a deployed condition of the airbag cushion. At least one energy absorbing (EA) element is connected to the airbag cushion acting to restrict a fore-aft motion of the airbag cushion.
