The invention relates to a motor vehicle with a window regulator for a side window of a motor vehicle with the features from the preamble of patent claim 1.

For the technical environment, for example, refer to the European patent application EP 1 526 242 A2 pointed out. This published application discloses a method for controlling the movement of a side window of a side door of a motor vehicle that can be moved by means of a power window lifter. In the proposed method, depending on a movement of the side door, the side window is automatically moved by the window lifter into a predetermined intermediate position, which deviates from a fully closed or lowered position of the side window. In order to avoid rattling noises from the side window, it is provided that, starting from the completely lowered position of the side window, the side window is raised at least when the side door is closed into the intermediate position in which the side window with its upper edge at least partially falls into one on the upholstery of the side door lying sealing gap is moved into it.

Another window lifter for a motor vehicle door is known, for example, from the German Offenlegungsschrift DE 102 04 610 A1 known. A window regulator, in particular a cable or tubular window regulator, for a frameless motor vehicle window is disclosed, with at least one guide rail extending along the adjustment path of the window pane, with adjustment means for adjusting the inclination of the at least one guide rail with respect to one of the longitudinal axes of the motor vehicle Level, and with locking means for locking the adjusted position of the guide rail with respect to a body part or a part connected thereto. The adjusting and locking means are provided in the lower area of the guide rail as screw connections, with the adjusting means having an adjusting screw pre-assembled on the lower end of the guide rail and extending approximately transversely to the longitudinal axis of the motor vehicle, which can be tightened by means of a form-fitting area arranged at one of its ends is rotatably mounted in a corresponding area of the body part or the like.

From the German Offenlegungsschrift DE 10 2017 001 510 A1 a door structure for a motor vehicle is known, comprising:

• a door frame including vertical frame portions provided on both side portions in a vehicle front-rear direction of the door frame, and a plurality of connecting members connecting the vertical frame portions, the vertical frame portions being a light metal casting,
• wherein the plurality of connecting members is a hollow, light metal extrusion; and a door outer panel formed in a non-planar shape, wherein the plurality of links of the door frame includes an inward link positioned on an inward side in a vehicle width direction of the door frame, and an outward link .comprise external connecting link,
• which is positioned on an outward side in the vehicle width direction of the door frame, the vertical frame portions of the door frame are provided with projection portions,
• each of which engages the inside link substantially in a longitudinal direction of the inside link, a plurality of fixing portions which fix the outside link and the vertical frame portions are provided at different points in a longitudinal direction of the outside link, and the outside lying link is provided with a rib or flange which engages with a groove provided at an upper portion of the door outer panel.

Even if the known prior art has no serious disadvantages, the present invention is based on the object Show measure to improve the structural rigidity of a side door of a motor vehicle.

This object is achieved for a generic motor vehicle with a window regulator by the features in the characterizing part of claim 1 in that a first side impact beam, which extends largely in an X-direction, can be arranged on the first window regulator guide rail and between the first window regulator A first connecting element can be arranged between the guide rail and the first side impact beam, the first window lifter guide rail and the first side impact beam being arranged between a door outer panel and the side window.

The structural rigidity of the side door of the motor vehicle is significantly increased due to the design of the motor vehicle according to the invention with a window lifter. Advantageously, the necessary effect against objects penetrating into the interior of the motor vehicle is provided, or the deformation of the side door when a force is applied is significantly reduced, thereby improving motor vehicle safety.

Advantageous developments of the invention are described in the dependent claims.

The configuration according to claim 2, that the first window lifter guide rail and/or the first side impact beam can be connected to the first connecting element in a non-positive and/or positive and/or material-locking manner, are connection methods known to the person skilled in the art. Advantageously, he is able to present the most suitable connection technology for every motor vehicle and every motor vehicle side door.

The configuration according to patent claim 3, that the first window lifter guide rail has a stiffening structure, for example a beading, increases the structural rigidity of the side door again considerably.

According to patent claim 4, a first possibility of this improvement is that the stiffening structure is in one piece and is made of the same material as the first window lifter guide rail. As a result of this measure, components are reduced and at the same time the tolerance positions relative to one another are improved.

According to patent claim 5, a second possibility for achieving the aforementioned advantage is that the stiffening structure is a separate component and can be connected to the first window lifter guide rail. A stiffening structure is understood to mean, for example, an accumulation of material, such as ribs or webs or local material reinforcements. Another way of representing a stiffening structure is to design a sheet metal component with a defined profile, for example.

According to patent claim 6, the first connecting element preferably consists of an iron material and/or a light metal and/or a plastic. This means that the connecting element consists either of a single one of the above Materials or a mixed structure, such as a ferrous material and a plastic or a light metal and a plastic or a ferrous material and a light metal. With these possible combinations, the most varied of force introductions into the side door structure can be implemented.

A further possibility to improve the structural rigidity of the side door of a generic motor vehicle is that the first window lifter guide rail and/or the first side impact beam has a material reinforcement in a first overlapping area with the first connecting element. This can be represented, for example, by a thickening or widening of the first window lifter guide rail and/or the first side impact beam.

In a further development of the invention, the first window lifter guide rail protrudes as far as a lower edge of the side door. In this way, the dissipation of force when a force acts via the first window lifter guide rail in the side door structure can be represented very well.

A further improvement in the energy dissipation from the first window lifter guide rail into the side door structure is that the first window lifter guide rail projects to a lower edge of a window opening in the side door.

According to patent claim 10, this extension of the first window lifter guide rail to a lower edge of a window opening makes it possible for a second side impact beam, which extends largely in the X-direction, to be arranged on the first window lifter guide rail below the window opening and above the first side impact beam . This further measure leads to an even greater structural rigidity of the side door of the motor vehicle according to the invention.

According to patent claim 11, a second connecting element can advantageously be arranged between the first window lifter guide rail and the second side impact beam.

As is already the case for the first connecting element, the first window lifter guide rail and/or the second side impact beam can be non-positively and/or positively and/or materially connected to the second connecting element. This in turn leads to the advantage mentioned above.

In a further development according to patent claim 13, that the first window lifter guide rail and/or the second side impact beam has a material reinforcement in a second overlapping area with the second connecting element, the structural rigidity of the side door is optimized.

Like the first connecting element, the second connecting element can also consist of an iron material and/or a light metal and/or a plastic.

In a further development of the invention, according to claim 15, a second window regulator guide rail can be arranged parallel to the first window regulator guide rail. Thus, a window lifter is shown that is also ideally suited for front side doors of a motor vehicle.

With the configuration according to claim 16, wherein the side door has a reinforcement of the door outer panel between the door outer panel and the side impact beam, that the window lifter guide rail is connected to the reinforcement of the door outer panel, the rigidity of the side door is further improved without increasing the weight.

The configuration according to patent claim 17, that the window lifter guide rail is screwed to the reinforcement of the outer door panel, is a preferred embodiment.

The configuration according to patent claim 18, in which the reinforcement of the outer door panel is beaded, further increases the inherent rigidity of the reinforcement of the outer door panel. Since this type of increase in rigidity does not require additional struts/reinforcing elements, greater robustness/rigidity can be achieved without additional weight.

• 2 shows schematically a cross section through a side door of a motor vehicle.
• 3 shows a top view of two window regulator guide rails and a first side impact beam.

The following apply in the 1 until 5 the same reference numerals for the same components.

1 shows a top view of a window regulator for a motor vehicle according to the prior art. A door outer panel of a side door 3 of the motor vehicle is not shown, so that the window lifter 1 can be seen. In the present exemplary embodiment, the window regulator 1 consists of two window regulator guide rails 4 arranged parallel to one another, of which only one, the left, is numbered. With the window lifter 1, a side window 2 in the side door 3 of the motor vehicle can be displaced largely in a Z-direction into an upper position O and a lower position U. These two positions are in 2 shown. Here, the two power window guide rails 4 extend largely in the Z direction. A non-visible rail slider 5 is arranged in a sliding manner on the window regulator guide rail 4, the side window 2 being held in the present exemplary embodiment by two pane holders 6, one for each window regulator guide rail 4, which are arranged on the rail sliders 5. In a further exemplary embodiment, the rail slider 5 can also assume the function of the pane holder 6. A separate disc holder 6 can then be omitted. An electrical adjustment mechanism with Bowden cables is not shown in numbers. Also shown in the side door 3 is a side impact beam 7 extending largely in an X-direction.

The X-direction is understood to mean a vehicle longitudinal axis, the Y-direction a vehicle transverse axis and the Z-direction a vehicle vertical axis. This is in a coordinate system at the bottom right next to the 1 until 5 shown.

Even if the known prior art does not have any serious disadvantages, the present invention is based on the object of demonstrating a measure for improving the structural rigidity of the side door 3 of the motor vehicle.

2 shows a YZ section through a side door 3 of a motor vehicle according to the invention with a window regulator 1. A door outer panel 9 of the side door 3 extends over the window regulator 1 according to the invention. The YZ section is deliberately shown very schematically in order to show only the essential components. As is known from the prior art, the side window 2 in the side door 3 of the motor vehicle can be displaced largely in the Z-direction into an upper position O (closed) and a lower position U (open) with the window lifter 1, represented by a dashed line double arrow. The window regulator 1 has at least one first window regulator guide rail 4, which extends largely in the Z-direction and on which a rail slider 5 is arranged in a sliding manner, the side window 2 being held by at least one pane holder 6 which is arranged on the rail slider 5 is. In a further exemplary embodiment, the rail slider 5 can also assume the function of the pane holder 6. A separate pane holder 6 can then be omitted, also within the scope of the present invention.

Furthermore, a reinforcement of the door outer panel 16 is arranged in the side door 3 between the door outer panel 9 and the side impact beam 7 . This additionally increases the stability of the side door 3 .

According to the invention, a first side impact beam 7 is arranged on the first window regulator guide rail 4 and extends largely in the X-direction. Furthermore, a first connecting element 8 can be arranged between the first window lifter guide rail 4 and the first side impact beam 7 , the first window lifter guide rail 4 and the first side impact beam 7 being arranged between the door outer panel 9 and the side window 2 .

in the in 2 illustrated embodiment, the first window lifter guide rail 4 extends both to an in 2 not shown lower edge of the side door 3, and up to a lower edge of a disc opening of the side door 3. This corresponds approximately to the area in which the door outer panel 9 extends in the direction of the side window 2. Due to this configuration, the structural rigidity of the side door 3 is increased and if forces should act on the side door, these are ideally transferred to the door structure. The penetration of foreign objects into a passenger compartment of the motor vehicle is prevented. Furthermore, due to this design, a second side impact beam 11, which also extends largely in the X-direction, can be arranged on the first window lifter guide rail 4 below the window opening and above the first side impact beam 7. In addition, a second connecting element 12 can also be arranged between the first window lifter guide rail 4 and the second side impact beam 11 .

For both the first connecting element 8 and the second connecting element 12, the first window lifter guide rail 4 and/or the second side impact beam 11 can be connected to the second connecting element 12 in a non-positive and/or positive and/or material connection. These manufacturing options enable the person skilled in the art to produce the best possible connection technology for each side door 3 of a motor vehicle in order to increase the structural rigidity of the side door 3 .

In an embodiment that is not shown, the window lifter guide rail 4 is connected to the reinforcement of the outer door panel 16, as a result of which the rigidity of the side door 3 is further improved without increasing the weight. This connection can preferably be made by a known screw connection.

In an embodiment that is also not shown, it is beaded. Beaded means that a cross-section of these components has a structure, such as a corrugated shape, to increase structural rigidity. This can be done, for example, by embossing or forming. This again increases the inherent rigidity of the reinforcement of the outer door panel 16. Since this type of rigidity increase does not require additional struts or stiffening elements, greater robustness or rigidity can be achieved without additional weight.

3 shows how 1 . In a preferred embodiment, the first window lifter guide rail 4 has a stiffening structure 10, which is represented by a bead in the present exemplary embodiment. This means that the stiffening structure 10 is in one piece and of the same material as the first window regulator guide rail 4 . In this embodiment, only a few components are required, while at the same time the best possible tolerance position for add-on parts is achieved.

In a further exemplary embodiment, the stiffening structure 10 is a separate component and can be connected to the first window lifter guide rail 4 . Next is in 3 the first side impact beam 7 can be seen, which extends largely in the X-direction and covers the first and the second window regulator guide rail 4 in a crossing manner. This results in two overlapping areas 14, only one of which is numbered, represented by dashed rectangles.

In a preferred embodiment, the first window lifter guide rail 4 and/or the first side impact beam 7 has a material reinforcement in a first overlapping area 14 with the first connecting element 8 . This serves to further improve the structural rigidity of the side door 3.

The first connecting element 8 is preferably made of an iron material and/or a light metal and/or a plastic. The person skilled in the art thus has a large selection of materials to increase the structural rigidity of the side door 3 for the particular case at hand. Material mixtures can of course also be produced, for example from a ferrous material with a light metal or a light metal with a plastic or a ferrous material with a plastic. Fiber composites can also be used.

Of course, all of the features mentioned above also apply to the second side impact beam 11 in conjunction with the second connecting element 12.

4 shows a YZ section through a window regulator guide rail 4, a first connecting element 8 and through a first side impact beam 7. For safety reasons, the first side impact beam 7 has a corrugated structure for particularly good structural rigidity. Material reinforcements can be seen at the upper and lower end (Z ends) of the first side impact beam 7 , which engage in unnumbered undercuts of the first connecting element 8 . Next is in 4 recognizable that the window lifter guide rail 4 also has tabs which engage in further, unnumbered undercuts of the first connecting element 8 . This is just one of many mounting options. In other exemplary embodiments, the connecting element 8, the first side impact beam 7, and the window regulator guide rail 4 can also be screwed, clinched, riveted, glued, etc. to one another, for example.

5 shows a second embodiment of the first connecting element 8, which is constructed from two different materials. Identical to 4 the first side impact member 7 in turn engages in undercuts of the first connecting element 8 in the Z direction. In 5 the first connecting element 8 on the side impact beam side consists, for example, of an aluminum material, while another material, such as a plastic, can be used between this first part and the first side impact beam 7 . This choice of material enables a defined introduction of force into the window lifter guide rail 4 .

• Erfindungsgemäß kann der Fensterheber 1 neben der Funktion des Hebens und Senkens der Seitenscheibe 2 auch die Struktursteifigkeit der Seitentür 3 verbessen. Dies kann durch die erfindungsgemäße Ausgestaltung optimiert werden. Um die oben erwähnte Krafteinleitung über einen Seitenaufprallträger 7, 11 und einen außenliegenden Fensterheber zu realisieren, ist eine Verbindung zwischen dem Seitenaufprallträger 7, 11 und der Fensterheber-Führungsschiene 4 von Vorteil. Diese Verbindung erfolgt mit einem oder mehreren entsprechenden Elementen, welche entweder auf den Seitenaufprallträger 7, 11 oder an der/den Fensterheber-Führungsschienen 4 verschraubt, verklebt oder anderweitig mechanisch / formschlüssig verbunden werden kann. Das Verbindungselement 8, 12 kann beispielsweise aus Aluminium, Kunststoff oder Stahlblech sein. Das Patent soll an dieser Stelle die Idee eines zusätzlichen Verbindungselementes 8, 12, welches zwischen dem Seitenaufprallträger 7, 11 und der Fensterheber-Führungsschiene 4 platziert wird, schützen.

In summary it can be said:

• According to the invention, the window regulator 1 can improve the structural rigidity of the side door 3 in addition to the function of raising and lowering the side window 2 . This can be optimized by the configuration according to the invention. In order to implement the above-mentioned introduction of force via a side impact beam 7, 11 and an external window regulator, a connection between the side impact beam 7, 11 and the window regulator guide rail 4 is advantageous. This connection is made with one or more corresponding elements, which can either be screwed, glued or otherwise mechanically/positively connected to the side impact beam 7, 11 or to the window lifter guide rails 4. The connecting element 8, 12 can be made of aluminum, plastic or sheet steel, for example. At this point, the patent is intended to protect the idea of an additional connecting element 8, 12, which is placed between the side impact beam 7, 11 and the window regulator guide rail 4.
