Abstract: An example retention assembly has a motor assembly and a self-locking worm drive coupled thereto. A cam is fixed to a worm gear of the worm drive. The retention assembly has an actuation shaft including a follower. The actuation shaft is displaceable over a displacement range via rotation of the cam. The retention assembly has a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly has a housing cam included as part of the retention assembly housing and against which the securement member follower is biased. The securement member are in an open state when the actuation shaft is in a first position. The securement member swings outward to a retaining position as the actuation shaft is moved to a second position.
