Compartment shade

摘要

A trunk shade for an automotive luggage compartment having a central torque tube removably installed and held against rotation in fixed mounting brackets in which a torsional windup spring accommodating shade extraction and retraction has a prewind retention feature provided by an axial lead screw for a clutch dog which reaches a limit stop at a prewound retracted condition unaffected when the shade is removed from the mounting brackets. Optionally, a stop may also be provided at the other end of its travel to limit extraction of the shade. Helical torsional windup springs, of either compression or extension type, are adapted to take up mounting end clearance and in other respects eliminate shade rattle.
