An automobile window shade system comprising a frame (20) formed of horizontal tubular elements (20a through 20c) and vertical tubular elements (22e through 22f) interconnected by T-shaped connectors (24a through 24f). The frame is installed inside the automobile body and contains a cord (42) guided through a plurality of guiding means (64, 66, and 68). Two adjacent shades (94 and 96) which are made of a light-impermeable flexible material are attached to a yoke (84). One end of the yoke is located inside the vertical tubular element (22e through 22f) between two stops (88 and 90) which are rigidly attached the cord. The cord is also connected to a handle (110). When the handle (110) is moved in the window shading direction, it moves the cord (42) and hence the stops (88 and 90). When the upper stop (88) comes into contact with the yoke (84) it moves the yoke and the shields (94 and 96) down, thus shading the windows. An embodiment with a beaded thread (128) and the expandable spring-loaded C-shaped portion of the yoke makes it possible to shield and unshield windows selectively. A motorized version with a drive motor (150) provides mechanized shading and unshading. For this purpose, a portion of the cord comprises a roller chain (156) which is in mesh with a sprocket (154) attached to the output shaft of motor (150). The system may be hidden under the panels of the car interior or attached directly to the outer surface of the panels.
