ABSTRACT:
A window shade particularly for use with a motor vehicle window including a shade supported at one edge by a winding shaft and a pull strip located at the other edge of the shade for unwinding the shade from the winding shaft. For guiding the movement of the shade onto and off the winding shaft, a guide device comprised of two pairs of toggle links is provided. Each pair of toggle links is attached by a pivot connection at one end. The opposite end of one toggle link is pivotably attached to a fixed location. The opposite end of the other toggle link is pivotably attached to the pull strip. A strut extends between the pivot locations where the two pairs of toggle link arms are connected. Each toggle link arm is connected to the strut at a main pivot and at a second location and the strut is slotted to receive both connections from each link arm and to permit the toggle links connections to move through an arcuate pathway as the pull strip is moved. At least one of the toggle link arms may be braked, resisting winding and unwinding of the shade.
