Abstract

A latch assembly for driving a closure panel from a closed panel position to an open panel position. The latch assembly comprises: a latch mechanism having a first latch element for retaining a mating latch component in a latched position and for moving the mating latch component from the latched position to an unlatched position when released, the movement of the first latch element biased towards the unlatched position by a latch biasing element; and an actuation system having: a mechanical energy storage system having a device for storing mechanical potential energy for assisting the latch biasing element in moving the mating latch component from the latched position to the unlatched position; a mechanical advantage system having a plurality of advantage elements for engaging the device, such that movement of the plurality of advantage elements is associated with a trigger force and cooperation of the plurality of advantage elements provides for amplification of the trigger force as an initiating force to release the stored mechanical potential energy; and a trigger system configured to provide the trigger force to release the stored mechanical potential energy.
