Abstract
In a rear-window roller blind for motor vehicles in which a rear half of a back-seat shelf, which is located between the rear window and the pull-out slot for the rear-window roller blind, is used as a support element for the roller blind. The back-seat shelf half is made either from a wood material or is a plastic molded part. Through alternative arrangements, it is ensured that the temperature expansion and contraction of the components of the roller blind and its support are accommodated.
Claims31
In a motor vehicle having a back seat and a rear window comprising:
- 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 of a non-metallic material with a temperature coefficient of expansion that differs by less than 30% from the temperature coefficient of expansion of steel,
- a pair of bearing devices (47) mounted on said 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.

In a motor vehicle comprising a car body 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 steel,
- a pair of bearing devices (47) mounted on said carrier element (14),
- 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.
