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.
