Patent ID: 7942463

Claim:
In a motor vehicle comprising a car body made of metal having a back seat and a rear window, a rear-window roller blind, a back-seat shelf ( 12 ) fixedly mounted between said back seat and rear window ( 5 ), said back-seat shelf ( 12 ) having a front region and a rear region ( 14 , 15 ) adjacent the rear window, said front and rear regions ( 44 , 45 ) defining a pull-out slot ( 13 ) extending over the length of the back-seat shelf, said rear region ( 14 ) of the back-seat shelf being formed by a carrier element ( 14 ), made from a plastic having a greater temperature coefficient of expansion than the metal from which the car body is made, a pair of bearing devices ( 47 ) mounted on said carrier element ( 14 ) for relative movement in a direction parallel to the pull-out slot, at least one spacer element ( 61 ; 40 , 41 ) for maintaining the distance between the bearing devices ( 47 ) independent of changes in temperature and differences in temperature coefficients of expansion between the car body and carrier element ( 14 ), said rear window roller blind including a wind-up shaft ( 23 ) connected to the carrier element ( 14 ) by means of said bearing devices ( 47 ), a roll-up shade ( 22 ) having one edge attached to the wind-up shaft ( 23 ) and an opposite edge away from the wind-up shaft ( 23 ) is connected to a pull rod ( 21 ) which carries slides ( 30 ) on its ends, two guide rails ( 19 , 25 ) mounted in the motor vehicle which begin at the back-seat shelf ( 12 ) and in which the slides ( 30 ) of the pull rod ( 21 ) are movable by linear push elements ( 38 , 39 ) which are guided in said guide rails so that they are protected from buckling, a spring motor ( 24 ) coupled to said wind-up shaft ( 23 ) for biasing the roll-up shade ( 22 ) in a direction for winding onto the wind-up shaft ( 23 ), and a gear motor ( 36 ) mounted on the carrier element ( 14 ) for moving said linear push elements ( 38 , 39 ) in motion in sync and in opposite directions.
