Problems solved by technology

Lack of parallelism will pull the window shade web at an angle, causing diagonally extending ripples to appear on the unfolded window shade web
It's not pretty and doesn't serve the purpose

Embodiment Construction

[0034] In the schematic, figure 1 A rear view of a car 1 is shown, with a roof 2 , a trunk 3 , and two C-pillars 4 and 5 . The rear window 6 is between the two C-shaped pillars 4 and 5, the top is bounded by the rear edge 7 of the roof, and the bottom edge 8 of the rear window is the bottom. The rear window is mounted in the rear window 6 in a known manner, eg adhesively bonded by means of window rubber strips.

[0035] Rear window shelf 9 is positioned at the interior of car 1, is in the place ahead of rear window, and it extends horizontally between vehicle window lower edge 8 and the backrest of rear seat, is invisible in the figure. A linear outlet slot 11 extends on the rear window shelf 9 .

[0036] The outlet slot 11 is part of a rear window roll-up sunshade 12 , the basic structure of which is shown very schematically in side view in FIG. 2 .

[0037] The rear window roll-up sunshade 12 has two guide rails, and it is fixed along the side edge of the rear window 6 ne...

Abstract

A windup window shade has a windup shaft and a window shade web fastened on it. The window shade web is provided with a traction rod, which is moved at both ends by means of drive members along the guide rails. A compensating device is provided to compensate assembly tolerances or shape tolerances, which assures that too great tensions extending parallel with the windup shaft do not occur in the window shade web, which would lead to obliquely extending waves in the extended window shade web.

Description

technical field [0001] Unique to the body shape of modern cars is the large window area. Due to the strong sunlight, the large window area causes considerable heat generation inside the car. In the case of an air-conditioned car, excessive heat generation would result in undesirable energy consumption in order to counteract the thermal effect inside the car. Background technique [0002] For this reason, vehicles are increasingly being equipped with roll-up sunshades for the windows. [0003] In this regard, it is known to mount two guide rails laterally next to the window, in which the ends of the drawbars of the window sunshade web are guided. The length of the tow bar is adjustable to be able to accommodate different window widths. Actuation is by means of inserts moving on rails. [0004] The inserts can only be fully adjusted with very great force, so that they allow the movement of the window sun blind drawbar exactly parallel to the roll-up sun blind. If there is ...
