Abstract

A drive mechanism for a power closure latch includes a latch chassis, a power actuator fixed to the latch chassis, and a resilient member having a base at a first end and a second end that engages a drive member. The base is fixed to the latch chassis, and the drive member is driveable by the power actuator to compress the resilient member. The drive mechanism includes a toggle arm having an input and an output. The input is driveable by the drive member to toggle the output between a first position and a second position. A first end of a second arm has a pivot fixed to the latch chassis and a second end having an input for attachment to the drive member. Driving of the drive member by the power actuator to move the output from the first position to the second position causes compression of the resilient member, and driving of the drive member by the power actuator to move the output from the second position to the 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 member.
