<p>A drive mechanism for a power closure latch, comprising: a latch chassis and a power actuator fixed to the chassis; a resilient means having a base at a first end and engaging a drive member at a second end, the base being fixed to the chassis and the drive member being driveable by the power actuator to compress the resilient means; a toggle arm having an input and an output, the input driveable by the drive member to toggle the output between first and second positions; a second arm having a pivot fixed to the chassis at a first end and an input at a second end for attachment to the drive member, in which driving of the drive member by the power actuator to move the output from its first position to its second position causes compression of the resilient means, and driving of the drive member by the power actuator to move the output from its second position to its first position to deliver an output load for driving an associated power closure latch is assisted by a spring load generated by expansion of the resilient means.</p> |
