Description

Slide guide for a retractable window pane of a motor vehicle door The invention relates to a sliding guide for a retractable window pane a motor vehicle door which at the same time forms the lower edge of the window opening with its upper edge with two guide channels in the door near the side edges of the window pane, in each of which one attached to the lower ends of the side edges of the window pane, with one upper and one lower guide body each guide member displaceable is, the guide troughs in the sense of a lateral inclination of the window pane in the last area of their upward movement against a fixed on the vehicle Sealing strips and in the sense of a pivoting of the window from this sealing strip are curved in the first area of their downward movement.

In order to have an uneven concern or Pinching the upper end of the window pane on the fixed sealing strip To avoid the vehicle body, it is advisable that the disc only in the last Section of their upward movement pressed sideways from the outside against the sealing strip causing unnecessary inhibition of the window movement and wear and tear on the sealing strip be avoided. While such a known construction has the disadvantage that the pane on the lower edge of the window of the door is one compared to the pane thickness Requires a much wider slot and the window guide, moreover, almost as well the entire width of the door recess takes up what a versatile application opposes the window guide in door structures of different widths also another window guide not previously known compared to the present invention the lack that the pane on the lower edge of the window opposite the door the thickness of the pane requires a much wider slot, which is responsible for the seal there difficult and otherwise due to its width (especially when the window is open) disturbs.

The invention is based on the object of the aforementioned shortcomings to avoid and to perfect the aforementioned sliding guide so that despite a lateral pressing of the in its upper position located disc on the lower edge of the window only one the slice thickness closely matched slot guide is required.

According to the invention, the object set is essentially thereby solved that the window pane of the sliding in the guide channels lower Guide bodies of the guide member in connection with a known per se, along the upper edge of the motor vehicle door and holding the window pane Slot guide is guided, but only near and in the upper end position the window pane an additional guide through the also in the guide channel sliding upper guide body takes place, and that the length of the movement paths the number of leading members is limited.

With such a design, the sliding guide forms on the lower edge of the window and at the same time located on the top edge of the door slot a fixed guide for the window pane, which is shifting around the joint formed thereby is pivoted. The slot guide can therefore easily be narrow in its width to be adapted to the thickness of the pane, which makes a simple and at this point but effective sealing option is created.

In the drawings, the invention is illustrated by way of example; it shows F i g. 1 shows a motor vehicle door corresponding to the first exemplary embodiment in a partial side view showing the pane guide, FIG. 2 the door according to F i g. 1 in a vertical cross-section (with the window pane completely lowered), F i g. 3 the same door with the window pane completely raised in one of the FIGS. 2 similar partial cross-section, F i g. 4 one of the F i g. 2 corresponding cross-section a motor vehicle door according to the second embodiment, F i G. 5 one of the F i g. 3 corresponding partial cross-section of the door according to FIG. 4, F i g. 6 shows a detail of the door according to FIGS. 4 and 5 in a side view.

The in the F i g. 1 to 3 shown, the first embodiment Corresponding motor vehicle door 7 forms part of the vehicle body of a Limousine and its upper edge only extends up to the height of a conventional one horizontal median of the motor vehicle, over which the window opening connects. For example, there is one on the vehicle body above the window opening of the closed door made of rubber or some other elastic, resilient material (not shown) Sealing strip fastened against which the window pane brought into its upper end position 8 lies in a sealing manner when the door is closed. The window pane 8 can be used to and downward movement by any conventional actuating mechanism (not shown) be coupled, which is arranged within the motor vehicle door and, for example engages the lower edge of the window pane 8.

As shown in FIGS. 2 and 3 is apparent along the top of the Motor vehicle door 7 is an elastic sealing strip, for example made of plastic 9 arranged, the one of the pane thickness and pane width corresponding slot has, in which the window pane 8 sealingly in its upward and downward movements is led. The sealing strip 9 is useful at its lower end with two against the pane surface directed ribs 9 a provided for the window pane 8 at the same time form a guide. Located at the upper, outer end of the sealing strip 9 on both sides of the window pane 8 each expediently a bead 9 b, the inner one Part sealingly against the window pane 8, while its outer part respectively sealingly rests against the upper edge of the motor vehicle door 7 there.

In each case at the lower end of each vertical or approximately vertical The side edge of the window pane 8 is also made of plastic, for example existing guide member 10 attached, which in one in the motor vehicle door 7 arranged guide channel 11 is guided. Each guide member 10 has on his upper end designed as a guide body 10 a and at its lower end one designed as a guide body 10b, which is somewhat larger than the aforementioned one Expand to.

The guide channels 11 are expediently arranged so that their two side legs located on both sides of the window pane 8 run approximately parallel to this and enclose the two guide bodies 10 a and 10 b of the associated guide member 10 on both sides. At its upper end, each guide channel 11 has a part IIa that is narrowed compared to the width of the rest of the channel, into which the upper (smaller) guide body 10a can penetrate, but which is smaller than the lower guide body 10b of the associated guide member 10, so that thereby. an upward movement of the window pane 8 out of the motor vehicle door 7 is made impossible. Furthermore, each guide channel 11 in its upper part has a certain lateral expansion towards the outside of the door in order to give the window pane 8 guided on it via the guide members 10 an inclination towards the inside of the closed vehicle during the upward movement.

When the motor vehicle door 7 is closed and the window 8 is completely is brought into its upper end position (see FIG. 3), the upper guide body is located 10a of the guide member 10 tightly between the side legs of the upper, narrowed Part 11a of the guide channel 11 fixed, while the lower guide body 10b the same guide member 10 at the lower, still correspondingly wider end of the tapered upper part 11a of the guide channel 11 is fixed. As a result, the window pane 8 in this position safe against the one on the vehicle body, earlier said sealing strip (not shown) pressed on and results in a good seal opposite the upper part of the vehicle body.

In particular from FIGS. 1 and 2 it can be seen that at least a guide member 10 and a pin 12 running transversely to the window pane 8 or the like approach that carries in the upper end position of the window pane 8 against a local lateral projection 13 of a side leg of the associated Guide channel 11 rests and thereby the further upward movement of the window pane 8 prevented.

If the window pane S, which is in its upper end position with the vehicle door closed? moves downwards again, so the one at first takes care of it along the bend of the guide channel 11 again towards the inside of the closed Vehicle moving guide body 10 b in conjunction with the slot guide of the Sealing strip 9 for an outward inclination of the upper part of the window pane 8, whereby they are pivoted outwards from the fixed upper sealing strip of the vehicle body will. The fact that the upper, narrowed part 11 a of the guide channel 11 slightly expanded downwards and the upper guide body 10 a of the guide member 10 widened in this with the increasing downward movement of the window pane 8 Part reached, the mentioned pivoting of the window pane 8 is also at this point enables.

The same parts result when the window pane is moved upwards 8 the above-mentioned pivoting of the window pane with its upper part against the Vehicle, being pressed against the upper sealing strip on the vehicle body is when the motor vehicle door 7 is closed or closed beforehand was.

Each guide body 10 a and 10 b is rounded towards the side legs serving to guide it and also towards the bottom of the associated guide channel 11 so that the guide member 10 is pushed back and forth in the guide channel 11 as easily and without friction as possible and according to the bend of the guide channel can also be swiveled.

From the F i g. 1 and 2 can also be seen that each guide trough 11 is adjustably fastened in the motor vehicle door 7, so that manufacturing inaccuracies Compensated by slight adjustment movements on all sides of the guide trough can be. For this purpose, each guide channel 11 in the area of its lower End of a tab 14, by means of which the guide channel l1 via a conventional Screw connection can be screwed to a bracket 15 fixed within the motor vehicle door 7 can. One or both of these tabs 14 and 15 have a screw interspersed elongated hole, so that the guide channel 11 when assembled by a shifted corresponding amount in their longitudinal direction or against the window pane 8 or can be pivoted away from this. In addition, the direction of the Guide channel 11 can be changed with respect to the adjacent inner door wall by that when attaching the screw connection between the two tabs 14 and 15 more or fewer washers 16 are inserted. To the corresponding swivel movements to enable, the guide channels 11 are each at their upper ends with one Tab 17 provided, but in a perpendicular to the plane of the tabs 14 and 15 located level and via a screw connection to one there located inside the door flap 18 are attached so that the guide troughs 11 is pivoted about the axes of the associated screws when the screw connection is loosened can be.

In the case of the corresponding to the second exemplary embodiment, shown in FIGS. G. 4 to 6, the motor vehicle door shown have the two guide channels 11 their entire length has a constant width. On the other hand, they are at their upper ones Ends with longer side legs than on their other parts, whereby leg parts 11b which protrude further from the bottom of the channel result. Furthermore these guide troughs also have bends towards the outside of the door, around the window pane 8 as a result of their upward and downward movements that already occur when first embodiment explained inclination movements to communicate.

As shown in FIGS. 4 and 5, in this embodiment the guide bodies 21 and 22 of each guide member 20 are located to the side of the pane plane and at the same time also in the direction of the pane plane outside the window pane B. These guide bodies 21 and 22 are also made of elastically flexible material and are inside each of the one Guide member 20 associated guide channels 11 slidably guided. The upper guide body 22 takes the place of the upper guide body 10a of the first embodiment and the lower guide body 21 of the guide member 20 takes the place of the lower guide body 10b of the first embodiment somewhat smaller mutual distance than the lower guide body 22 of the guide members 20, so that they are only guided in the further opposing upper leg parts 11 b of the guide channels 11 when the window pane 8 is in a correspondingly far out of the door position.

The guide members 10 or 20 can have recesses or slots be provided, which serve to increase their resilient deformability and Z. B. be filled with another suitable highly elastic material can.
