Reduce fuel wastage by preventing the automobile interiors from heating due to exposure to sunlight by deploying a automatic retractable shade

Objective & Product Overview

Product OverviewRetractable car shade a) is mounted on topb) deployed on demand and while the car is stationary c) Prevents heating of the car due to prolonged exposure by covering the top, front and rear windshields with a shade that reflects 50% of sunlight d) meets safety & compliance regulations

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.
