Abstract
An inflatable active bolster for a vehicle occupant, the bolster having a first body section and a second body section interconnected by a living hinge. The first and second body sections are folded about the living hinge to form a hollow chamber. The first body section provides an outer surface for facing the vehicle occupant, while the second body section provides a support surface for coupling the inflatable active bolster to a vehicle. At least one of the first and second body sections provides at least one expansible element such that upon pressurization of the hollow chamber, at least a portion of the at least one expansible element undergoes deformation to permit inflation of the hollow chamber, thereby displacing the outer surface of the first body section outwardly to an extended position.
