    摘要: An active material hood impact mitigation mechanism is activated in response to a signal generated from an impact sensor or pre-impact sensor or manually. The mitigation mechanism is capable of changing either reversibly or irreversibly the stiffness, shape, location, orientation, or displacement force of the hood either globally or locally, before an impact against the hood. The active material mitigation mechanism is held in a device designed to be installed in operative communication with the hood surface. The active material is characterized by a first shape or stiffness and is operative to change to a second shape or stiffness in response to the activation signal. Such active materials include shape memory alloys, electroactive polymers, shape memory polymers, magnetic shape memory alloys, magnetorheological fluids, magnetorheological elastomers, electrorheological fluids, and piezoelectric materials.

    摘要: 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.
