ABSTRACT:
Force and deceleration delimiting devices and methods for operating the same in a vehicle. The devices generally include an open celled material expandable from a non-expanded state to an expanded state, wherein the open celled material is sandwiched between a first end cap member and a second end cap member; an optional support surface cooperatively positioned with the open celled material to cover a surface of the open celled material in the expanded and the non-expanded states; and an optional shield cooperatively positioned with the open celled material to cover a surface of the open celled material in the expanded and the non-expanded states; and an activation mechanism adapted to regulate selective expansion of the open celled material from the non-expanded state to the expanded state in response to a triggering event, wherein the support surface and/or shield have a compact shape when the open celled material is in the non-expanded state and an expanded state when the open celled material is in the expanded state.
