Glare protection device for a vehicle

A glare protection device adapted to enable sunscreen material to be withdrawn to an extended position overlying a window or retracted to a stored condition comprising:

• a roll bar affixed to one edge of said sunscreen material whereby said sunscreen material may be rolled onto said roll bar in said stored condition or unrolled from said roll bar to said extended position,
• a pull bar engaging the edge of said sunscreen material opposite said edge affixed to said roll bar,
• a pair of laterally separated guide rails, said guide rails being flexible enabling them to be shaped to a desired configuration and defining an inside cavity and a longitudinal slot,
• a pair of hold bars extending from the ends of said pull bar and slidably received by said pull bar, said hold bar having ends engagable with said guide rails inside cavity whereby as said pull bars is moved between said extended and said stored positions, said hold bars are permitted to slide with respect to said pull bar, thereby following the contours of said guide rails,
• a flexible spiral element installed within said guide rail inside cavity and rotatable therein, said flexible spiral element engagable with said pull bar whereby rotation of said spiral element acts on said pull bar to move said pull bar longitudinally along said guide rails and further comprising:
• actuation means for causing rotation of said spiral element,
• transmission means for coupling movement of said actuation means to said spiral element, and
• spring means acting on said roll bar for maintaining said sunscreen material in a taut condition when said pull bar is moved between said extended and said retracted positions.

• a pull bar engaging the edge of said sunscreen material opposite said edge affixed to said roll bar,
• a pair of laterally separated guide rails, said guide rails being flexible enabling them to be deflected to a desired curved configuration,
• a pair of hold bars extending from the ends of said pull bar and slidably received by said pull bar, said hold bars having ends engagable with guide rails such that as said pull bar is moved between said extended and said stored positions, said hold bars are permitted to slide with respect to said pull bar, thereby following the contours of said guide rails,
• actuation means rotatably driving said roll bar, and
• biasing means acting on said pull bar for exerting a biasing force on said pull bar for maintaining said sunscreen material in a taut condition.
