Sun screen device for vehicles

摘要

The present invention refers to a sun screen device for vehicles in which glazed areas are present and therefore allow the sun's rays to pass. The device is intended to establish a barrier against the passage of the sun's rays in the area to be protected by means of extending a curtain. The curtain includes optionally on its end a sunshade in such a way that when the curtain is fully extended the sunshade is arranged in the manner of a visor on the upper part of the windshield. A special configuration of guide rails, pulleys and cable routers allows that in all degrees of extension of the curtain the main rod is perpendicular to the guide rails and the braking force is constant and controlled.
