Title: Carriage chassis with a tri-lobed torsion stop

Abstract: Carriage chassis for installation of a component assembly in a support structure. The support structure includes a power connector in a connector housing. The carriage chassis includes: rails adapted to receive a component assembly and a safety cover. One of the rails includes a tri-lobed torsion stop that includes a first lobe configured to contact the connector housing when no safety cover is installed, preventing a component assembly from coupling with power; a second lobe configured to receive contact from a displacement member of a safety cover, rotating the tri-lobed torsion stop; and a third lobe configured to provide contact to the displacement member when the safety cover is installed and a component assembly is coupled with power. The third lobe and the first lobe prevent removal of the safety cover when a component assembly is coupled with the power connector.
