Retractable Car Shade - Design
A flexible nylon polymer (or equiv) car shade material is wound on a Spindle. The spindle is mounted within a Housing that is operated using a stepper mode/nylon gear assembly installed in the End Covers. The car shade deployment and retraction is guided by guard rails.
