Abstract

An actuator assembly for moving a vehicle seat on a track includes an actuation cable having a first end and a second end, an actuation gear unit having an output gear with a spool feature attached to the first end of the actuation cable, a first biasing member, and an actuator in communication with the actuation gear unit. The output gear rotates about a first axis, the actuation cable partially windable upon the spool feature. Characteristically, the actuator when actuated rotates the actuation gear unit to wind the actuation cable onto the spool feature thereby retracting the actuation cable from a first position to a second position. Advantageously, the first biasing member biases the actuation gear unit to move the actuation cable from the second position to the first position.
