A wind-shield blind system to thermally insulate the windshield of a car. The system includes a spindle tube with a spindle tube mechanism which allows the blind to extend only, preventing the blind from being accidentally rewound by locking the spindle tube in a stationary position at any of a plurality of positions in its range of extension. The spindle tube mechanism includes a push block which, when activated, causes the blind to be automatically rewound.
