Carriage Chassis With A Tri-Lobed Torsion Stop

A support structure, the support structure comprising:

• support rails for receiving a carriage chassis, the carriage chassis configured to receive a component assembly for installation in the support structure;
• and
• a power connector in a connector housing, the power connector adapted to couple to a component assembly of the carriage chassis when the carriage chassis is installed in the support structure, wherein the carriage chassis further comprises:
• a plurality of rails adapted to receive a component assembly and adapted to receive a safety cover, wherein at least one of the rails comprises a tri-lobed torsion stop, the tri-lobed torsion stop comprising:
• a first lobe configured to contact the connector housing when no safety cover is installed in the carriage chassis;
• a second lobe configured to receive contact from a displacement member of a safety cover upon installation of the safety cover in the carriage chassis;
• and
• a third lobe configured to provide contact to the displacement member of the safety cover when the safety cover is installed in the carriage chassis and a component assembly installed in the carriage chassis is coupled with the power connector, wherein:
• the third lobe and the first lobe prevent removal of the safety cover when the safety cover is installed in the carriage chassis and a component assembly installed in the carriage chassis is coupled with the power connector.
