    Abstract: A hood lift mechanism for reversibly increasing the energy absorption capability at appropriate force levels of a vehicle hood includes a vehicle hood; an active material in operative communication with the vehicle hood, wherein the active material comprises a shape memory alloy, a ferromagnetic shape memory alloy, a shape memory polymer, a magnetorheological fluid, an electroactive polymer, a magnetorheological elastomer, an electrorheological fluid, a piezoelectric material, an ionic polymer metal composite, or combinations comprising at least one of the foregoing active materials; and an activation device in operative communication with the active material, wherein the activation device is operable to selectively apply an activation signal to the active material and effect a reversible change in a property of the active material, wherein the reversible change results in an increased clearance distance between the vehicle hood and an underlying component.

    Abstract: A hood elevation system for a vehicle includes an actuator configured to selectively move at least a portion of a vehicle hood between an elevated and a retracted position. The hood elevation system also includes a self-locking mechanism configured to allow movement of the hood between the elevated and retracted positions initiated by the actuator, but to resist retraction of the hood as a result of certain loads applied to the hood. The self-locking mechanism thus enables repeated elevation and retraction of the hood. In a preferred embodiment, the self-locking mechanism is configured to deform, thereby absorbing energy from an impact to the hood.
