Description

The The invention relates to a window blind for vehicle windows according to the preamble of claim 1.

From the DE 20 2004 020 095 U1 is a window blind for a vehicle window with a roller blind known, the peripheral edge with a portion of a winding shaft, which is rotatably mounted in a door or vehicle body or in a connected to the door or vehicle body blind box, and with an opposite portion on a Zugspriegel is attached. To avoid a Stofflosen the roller blind, which leads to a fluttering and shifting of the roller blind due to vibrations during driving when partially or completely deducted from the winding roller blind, if the blind is not kept sufficiently tight, the winding shaft is in respect to the door or Vehicle body stationary bearings stored, while a tensioning device acts directly on the surface of the runway and this deflects substantially perpendicular to the withdrawal direction of the winding shaft.

The Outlet opening of the door or vehicle body or of the roller blind box through which the roller blind led can, can by means of a suitably shaped Zugspriegels or by a flap that can be swiveled perpendicular to the withdrawal direction of the roller blind verschlos sen, which with a roller blind firming tensioning lever is connected, provided between the and the flap a recess is that the Zugspriegel wound up on the winding shaft Roller blind absorbs. When removing the roller blind from the winding shaft opens the Zugspriegel the flap and causes at the same time that with the flap connected tension levers on the surface of the Roller blind acts and tightens this.

task The present invention is for a window blind of the type mentioned above with a few components built, easy to install, requiring little space and reliable mechanism for self-closing the outlet after retraction of the tie rod in specify the roller blind box.

These The object is achieved by the features of claim 1.

The Solution according to the invention, in a window blind for a vehicle window with a roller blind whose circumferential Edge with a section on a winding shaft which is in a door or vehicle body or one with the door or vehicle body connected blind box is rotatably mounted, and with an opposite Section on a substantially parallel to the winding shaft extending and is attached to the winding shaft displaceable tension rod, and with an outlet opening of the door or Vehicle body or blind box closing and a perpendicular to the withdrawal direction of the roller blind extending Axis pivoting flap, which is operatively connected to a spring element is that biases the flap to release the outlet opening, to connect the spring element with a stop on which the between the stop and the flap with the outlet closed arranged tension rod rests and biases the spring element results a built with few components, easy to install, a space-consuming and functionally reliable mechanism for automatically closing the outlet opening after retracting the tension rod into the roller blind box.

Preferably are the spring element and the stop on the side facing the winding shaft arranged the flap.

In Another embodiment of the invention, the stop on a lever connected to the flap, which is preferably longer is as the height of the tie rod between the stop and the underside of the flap.

By this embodiment of the inventive solution ensures that the flap is opened, without coming in contact with the pull rod, so that it does not come to any Touch of visible parts and a thereby caused Abrasion or damage occurs. When removing the Roller blind from the winding shaft, the tension rod moves away from the Stop, due to the spring force of the spring element over the lever pivots the flap, so this at the opening in the opposite direction of movement, d. H. when winding the roller blind on the winding shaft, the Flap in the final phase of winding with the retraction of the tie rod into the roller blind box only after the complete immersion of the tie rod closed in the roller blind box when the tie rod at Abuts stop and the spring element biases and over the Lever closes the flap.

The Flap is such on the door or vehicle body or hinged on the roller blind box, the lever so connected to the flap and the lengths of the lever and / or the relaxed spring element are sized so that the flap in its open position around the outlet opening to the passage of the tension rod and the roller blind sufficient angle relative to the closed position the flap is pivoted.

The coupling of the flap with the Federele ment on the lever makes it possible to determine the opening angle of the flap required for the withdrawal of the roller blind from the winding shaft for mounting the window blinds with one or more functional elements. In the case of a predetermined articulation of the spring element on the door or vehicle body or on the roller blind housing, the length of the lever and / or of the relaxed spring element or the articulation of the lever on the door or vehicle body or on the roller blind box also determines the length of the lever on the door or vehicle body Flap by which angle the flap is pivoted after release of the stop by the pull rod. With sufficiently large spring force and low weight of the flap, the lever can be placed very close to the articulation of the flap on the door or vehicle body or on the roller blind, so that even small adjustment sufficient to the flap by a sufficient angle from the closed position in to pivot the open position.

In further embodiment, the flap protrudes in the open position essentially not over the plane of the exit opening out and is preferably in the open position the outlet opening enclosing parts of the window frame at.

In this embodiment of the solution according to the invention is the flap depending on the configuration of the outlet opening enclosing parts of the window frame by, for example, 160 ° to 180 ° pivoted, so they do not work in the open position protrudes into the field of view.

Preferably the spring element consists of a on the door or vehicle body or on the roller blind box supported compression spring.

Around make sure that the blind is completely on the by means of a spring motor or a torsion spring in the winding direction rolled up the blind sheet pre-tensioned winding shaft and the pull rod against the action of the spring element is completely retracted, the force of the spring motor or torsion spring is greater is as the spring force of the pull rod over the stop tensioned spring element.

The Invention will be described below with reference to the drawing Embodiments explained in more detail become. Show it:

1 a schematic side view of a part of a vehicle door with a window blind;

2 a section through the door sill of the vehicle door along the lines AA according to 1 with a roller blind box, whose outlet opening for the roller blind of the window blinds is closed by a flap and

3 a section through the door sill of the vehicle door along the line AA according to 1 with opened by pivoting the flap outlet opening.

1 shows a schematic side view of a vehicle door with a door body 1 in the one door opening 11 is provided by a vertically adjustable window 13 and a fixed, from the windowpane 13 through a gutter 15 separate, triangular window pane 14 is closed. For completely or partially covering the window pane 13 . 14 is a window blind 2 provided that from a roller blind 5 and a rolling mechanism with one inside a roller blind box 3 rotatably mounted winding shaft 4 exists between the inner panel and the inner lining of the vehicle door or parapet reinforcement of the below the door opening 11 provided door parapet 12 is arranged.

The on the winding shaft 4 wound up roller blind 5 has one of the shape of the windowpane 13 . 14 corresponding blank and a circumferential roller blind edge, the one on the winding shaft 4 fastened section as well as an opposite, with a pull rod or drawbar 6 contains connected section. The substantially perpendicular to the withdrawal direction of the roller blind 5 aligned tension rod 6 pulls the roller blind by means of a roller blind transport mechanism 5 from bottom to top, ie from the substantially horizontally extending door parapet 12 to the upper window frame edge of the winding shaft 4 from and is the curve of the upper window frame edge partially bent. For lateral guidance of the roller blind 5 are roller blind guide rails 71 . 72 provided the roller blind 5 when covering the windows 13 . 14 lead in deduction direction.

The roller blind transport mechanism can be moved from one of a drive device and with the pull rod 6 connected push rod or pull cables, which are inside the roller blind guide rails 12 . 13 and guided in arranged on the upper edge of the window frame pulleys and with the ends of the tension rod 6 are connected.

To cover the windows 13 . 14 becomes the roller blind 5 by means of the push rod or the traction cables of the winding shaft 4 deducted. For winding up the roller blind 5 on the winding shaft 4 can the winding shaft 4 be connected with a spring motor or with a torsion spring, which when removing the roller blind 5 from the winding shaft 5 is tensioned, so that at a reduction of the roller blind 5 from the winding shaft 4 pulling force the blind 5 in the opposite direction back to the winding shaft 4 is wound up.
