Claim:
A window shade assembly ( 14 ) for regulating the light admitted into the interior of a motor vehicle through a window ( 4 ) comprising: a rotatably supported winding shaft ( 19 ), a sunshade ( 15 ) having one edge fixed to the winding shaft ( 19 ), a pair of guide rails ( 16 ) extending laterally adjacent to the sunshade ( 15 ) for guiding movement of the sunshade between a retracted position and a completely extended position, an extension profile ( 21 ) of variable length that is connected to an edge of the sunshade ( 15 ) opposite the winding shaft ( 19 ) for movement with the sunshade between said retracted and completely extended positions, said extension profile ( 21 ) including a center section ( 26 ) and two telescopic sections ( 27 , 28 ) that are displaceably supported on the center section ( 26 ), said telescopic sections ( 27 , 28 ) having ends which are guided in the guide rails ( 16 ), a drive ( 41 , 25 ) that cooperates with said telescopic sections ( 27 , 28 ) for automatically moving said extension profile ( 21 ) and sunshade ( 15 ) to said extended position, a first centering device ( 46 ) fixed on a body of the motor vehicle at a location at which the extension profile ( 21 ) is positioned when the sunshade ( 15 ) is completely extended, and a second centering device ( 45 ) on the center section ( 26 ) of the extension profile ( 21 ), one of said centering devices ( 45 ) including a projection ( 48 ) directed toward the other of said centering devices ( 46 ), and said other centering device ( 46 ) including a recess opening in a direction toward the projection of the one centering device ( 45 ) for receiving and centering the projection ( 48 ) of the one centering device ( 45 ) as an incident to straight movement of the projection ( 48 ) of the one centering device ( 45 ) into the recess during automatic movement of said sunshade ( 15 ) by said drive ( 41 , 25 ) to said extended position for causing centering movement of the center section ( 26 ) of the extension profile ( 21 ) between the guide rails ( 16 ) without manual manipulation of said extension profile ( 21 ).
