Description

Window module for a motor vehicle

description

The invention relates to a window module for a motor vehicle according to the preamble of patent claim 1.

Such a window module comprises a window pane bounded by a circumferential outer edge and a window frame defining a window opening which can be closed by the window pane and which at least partially surrounds the window pane along its outer edge when the window pane is in the window opening, the window frame and the window frame Window pane form a preassembled window module outside a motor vehicle, which can be fastened as a preassemblable module assembly on a motor vehicle.

In this case, a window frame is generally understood to mean a limitation of a window opening in a motor vehicle which can be closed by a window pane provided for this purpose (which can be adjusted by means of a window lifter or possibly fixed). This may, for example, be a (at least.) Opening arranged on a motor vehicle door (in particular a folding door or sliding door) or on a non-movable region of a motor vehicle body defining a window opening partially enclosing), referred to as the frame boundary. In so-called frameless vehicle doors, which are used in particular as convertible vehicles, the associated window frame is formed by an area of the body-side boundary of the door opening, which can be closed by the corresponding vehicle door. As a window frame is that part of the boundary of the door opening, which limits intended with the vehicle door closed as intended on the vehicle door window glass (which is assumed in the case of an adjustable window glass from a window located in its closed position).

A window module of the type mentioned is known for example from DE 690 08 986 T2. Here, a window frame and a window pane comprehensive window module is attached as a preassembled module to a door of a motor vehicle door. Due to the associated separation of the window frame and door case, however, the very important in a crash case very important rigidity of a motor vehicle door is affected and it must be covered the interfaces between the window frame and door box for design reasons.

The invention is therefore based on the problem of further improving a generic window module.

This problem is solved according to the invention by the creation of a window module having the features of patent claim 1.

Thereafter, the window frame of the window module is set up, d. H. designed and provided for attachment to a body-side frame of a motor vehicle, which latter delimits the window pane on at least two different, mutually spaced plate edges and thereby at least partially surrounds. That is, the turquoise frame side frame includes at least two frame portions projecting from the door body at spaced locations in the vehicle longitudinal direction and each to be at least partially covered by and connected to a frame portion of the window frame.

In the case of the window module according to the invention, the window frame is designed in the manner of a panel which, after installation in a motor vehicle, extends along a body-side frame, in particular a frame of a motor vehicle door, and covers it. The stability of the corresponding body part, so For example, a door body of a motor vehicle is ensured in this case by the body-side frame, while the window frame of the window module separate thereof only serves to receive and guide the window and optionally for receiving an associated disc seal.

By this separation of functions, according to which the rigidity of the corresponding body assembly is ensured by a provided on the vehicle body first frame and the desired design is achieved by a window pane receiving and combined with this to a pre-assembled module, designed like a panel window frame, can be reconciling flexible pre-assembly of a window module with achieving high rigidity of the corresponding body assembly.

The body-side frame may in particular comprise two frame parts which are spaced apart from one another in the vehicle longitudinal direction and run essentially parallel to one another, which are each covered by one of two frame sections of the window frame which are spaced apart from one another.

Furthermore, the window frame can have an upper frame section which connects the two side frame sections spaced apart from one another in the vehicle longitudinal direction and extends as a roof-side frame section in the installed state, for example along the roof edge of a motor vehicle.

Attachment points, for example in the form of positive-locking areas, are provided on the frame sections of the window frame, via which frame sections can be fastened to an associated body-side frame on which the frame sections of the window frame rest when installed. The frame portions of the window frame are therefore not intended to be attached only with their in the installed state a door of a door body body facing ends to that door case, but they are rather provided with attachment points such that they can be fastened to a body-side frame, which are parallel extends to the frame portions of the window frame and adjacent thereto.

The fastening points in the form of positive-locking regions may be, for example, plug-in regions for forming a plug connection by insertion the plug-in areas of the window frame act in associated connection areas of the body-side frame, for example for producing a plug connection in the manner of a tongue and groove arrangement.

According to another embodiment of the invention, the form-fitting regions are formed by preferably hook-like, elastic latching or clip portions, which can be brought into engagement with associated connection regions of the body-side frame for producing a latching connection. Furthermore, fastening openings may extend along the frame sections of the window frame through which the window frame is fastened by means of screws or rivets to the associated body-side frame section.

Finally, at the frame portions of the window frame, adhesive or welding surfaces have been prepared, via which the window frame can be connected by an adhesive or by welding with the associated body-side frame.

Regardless of the specific design of the above fastening points is advantageous that the corresponding attachment points along the direction of extension of the individual frame sections of the window frame are arranged one behind the other, so that they are particularly suitable for connection to an associated body-side frame, which is parallel to the frame sections of Window frame extends and is covered by the window frame.

Preferably, both the window pane and the window frame made of plastic and the window frame forms a guide in which the window pane is adjustably guided. For this purpose, lateral window guides of the window frame extend beyond the upper area of the window frame, which defines a window opening, in order to allow the window pane to be lowered downwards out of the window opening by means of a window lifter.

In particular, when using plastic as a material for the window frame this can easily in one piece with another window, z. As a smaller triangular window, executed by a translucent plastic component is used for this purpose. Furthermore, the window frame is preferably provided with a disk seal, in a simple manner by the two-component technique (2K technique), using a softer plastic component for the Window seal as for the remaining areas of the window frame, integrally formed on the window frame.

A door assembly for a motor vehicle with a window module according to the invention is characterized by the features of claim 27.

Advantageous developments of this door assembly are specified in the dependent of claim 27 claims.

Further details and advantages of the invention will become apparent in the following description of exemplary embodiments with reference to the figures.

FIGS. 1a and 1b show a door assembly for a motor vehicle door, which has a door body 3 and a window module arranged thereon, consisting of a window pane 1 and a window frame 2, each made of plastic. The door body 3 comprises an upwardly bounded by a door parapet 34 door box 30, formed z. B. by an outer door skin and a door skin (especially in the form of a door outer panel and a door inner panel), which include a door shaft between them, as well as by two of the door box 30 -. with reference to the state installed in a motor vehicle - along the vertical vehicle axis z upwardly projecting, in the vehicle longitudinal direction x spaced from each other body side frame portions 31, 32 which define a window opening 20 on two sides.

The associated window module 1, 2 comprises a window pane 1 with two lateral edges 11, 12 which are spaced apart from one another in the vehicle longitudinal direction x and extend substantially along the vertical vehicle axis z, with an upper edge 13 and with a lower edge 14 arranged below the vertical vehicle axis z and a U-shaped along the two lateral edges 11, 12 and the upper edge 13 of the window glass extending window frame 2, wherein the window pane 1 with its two lateral edges 11, 12 longitudinally displaceable in associated side frame portions 21, 22 is guided. For this purpose, the respective lateral frame section (21, 22) has a guide (eg 21a) in the form of a guide channel, in which the window pane is mounted so as to be longitudinally displaceable and thus adjustable by a window regulator. In addition, a disk seal can be arranged in the respective guide channel (21a) or, in particular according to the so-called two-component technique, be molded.

The window frame 2 is connected to the door body in such a way that two frame sections 21, 22 of the window frame 2, which are spaced apart along the vehicle longitudinal axis x and extend substantially along the vertical vehicle axis z, are juxtaposed and secured to the corresponding frame sections 31, 32 of the door body 3 become. As a result, the window frame 2 with its lateral frame sections 21, 22 covers the lateral frame areas 31, 32 of the door body 3.

The window frame 2 has, in addition to the two lateral frame sections 21,

22 an upper, roof-side frame portion 23, from which the two side frame portions 21, 22 protrude in the manner of the legs of a U, such that the two side frame portions 21, 22 and the upper, roof-side frame portion

23 of the window frame 2 together with the parapet 34 of the door body 3 completely enclose a window opening 20 for the window pane 10.

The attachment of the window frame 2 to the two side frame portions 31, 32 of the door body 3 is effected by attachment points along the extension direction z of the side frame portions 31, 32 of the door body 3 and the lateral frame portions 21, 22 of the window frame 2 are arranged one behind the other.

A particular stability and rigidity of the illustrated in Figures 1a and 1b door assembly of a motor vehicle door is achieved in that the frame sections 21, 22 of the window frame 2 are not simply attached with their lower ends 21, 22 on the door box 30 but rather by several, along their Extension direction z successively arranged fastening points on the preferably integrally formed with the door box 30 of the door body 3, serving as structural structural components of the door body frame portions 31, 32 are fixed.

The window pane 1 is associated with a window regulator 4, which acts on a projecting from the lower edge 14 of the disk body 10 extension 14a and for lowering the window glass 1 from the window opening 20 and for re-raising the window pane 1 in the window opening 20 is used. The window regulator 4 has a drive 40, 41, comprising, for example, a drive motor 40 and a downstream transmission 41, and a traction means 42 coupled to the drive 40, 41, for. B. in the form of a rope, which is guided by means of deflecting elements 43 along a z in the adjustment of the window 1 gescheckten guide rail 45 and is provided with a fixed to the lower extension 14 a of the window pane 1 driver 44. This driver 44 is longitudinally displaceable with the guide rail 45 in engagement and can be lowered or raised by operating the drive 40, 41 in a known manner along the guide rail 45, wherein he takes the window pane.

2a shows a development of the door assembly shown in FIGS. 1a and 1b with a door body 3 which forms a door box 30 which is bounded above by a door parapet 34 and with a window module 1 secured thereto in the manner described with reference to FIGS. 1a and 1b. second

The window pane 1 of the window structure module 2 comprises a pane body 10, which is divided into two lateral pane edges 11, 12 spaced apart from the vehicle longitudinal axis x relative to the vehicle longitudinal axis x, an upper roof side pane edge 13 and one thereof along the vertical vehicle axis z spaced, the lower edge of the disc 14 is limited and the one through the window frame 2 together with the door parapet 34 defined window opening 20, see Figure 2b, closes. The same as the window pane 1 made of plastic existing window frame 2 has two along the vehicle longitudinal axis x spaced-apart side frame portions 21, 22 and a connecting them, roof-side frame portion 23, which surround the respective side edges 11, 12, 13 of the disk body 10 of the window pane 1, wherein the window pane 1 with their two lateral edges 11, 12 is longitudinally displaceable in the associated side frame portions 21, 22 is guided. Beyond the one side frame portion 22, ie on its side facing away from the other side frame portion 21, a triangular window 25 is integrally formed on the window frame 2 in one piece. This can be made of a different plastic than the frame sections 21, 22, 23 of the window frame 2, but integrally molded with this in one operation, for example, by the two-component technique (2K technique) when molding the window frame 2.

The two lateral frame sections 21, 22 each have a guide section 210, 220 adjoining thereon at the bottom, which extends below the window opening 20, cf. FIG. 2b, and underneath the door sill 34, and along which the window pane 1 can be lowered, as shown in Figure 2b, z. B. using a window lifter of the type shown in Figure 1a.

The assembly of the door assembly shown in Figures 2a and 2b is carried out as shown in Figure 3, characterized in that the window frame 2 and the window pane preassembled thereon 1 comprehensive window module 1, 2 is placed on the door body 3 and secured thereto. Specifically, the two side frame portions 21, 22 and the upper, roof-side frame portion 23 of the window frame 2 are set to hereby corresponding side frame portions 31, 32 and a connecting these upper, roof-side frame portion 33 of a body-side frame and attached thereto. The window frame 2 then covers the body-side frame in the manner of a panel.

The attachment of the window frame 2 on the body-side frame 31, 32, 33 via a plurality of attachment points, which are arranged in the overlapping region of the window frame 2 with the body-side frame 31, 32, 33, as shown in Figure 2c by way of example.

As can be seen by way of example in the case of a lateral frame region 31 of the body-side frame 31, 32, 33 and the associated frame section 21 of the window frame 2, as shown in FIG For this purpose, a latching opening 36 (which extends in the longitudinal direction of the respective frame area) is formed in the respective frame area (eg 31) of the body-side frame 31, 32, 33, which forms a frame having edge-side undercuts 37. These are engaged by hook-like end portions 27 associated latching elements 26 of the corresponding body-side frame portion 31 overlapping frame portion 21 of the window frame 2.

Instead of a positive locking connection between the window frame 2 and body-side frame 31, 32, 33, other fastening means may be provided, for. B. screws, the corresponding mounting holes in the window frame 2 and in the associated body-side frame 31, 32, 33 pass through; Clips that pass through through openings in the other component; a plug connection; a cohesive adhesive or welded connection or other known fastening elements. It is important that the attachment of the window frame 2 on the door body 3 is not only on the door box 30 facing ends of the side frame sections 21, 22 of the window frame 2, but in the areas where the window frame 2 and the relatively stiffer, body-side frame 31, 32, 33 cover each other. As a result, a special rigidity of the entire door assembly is achieved.

In the window module may further be integrated means for sealing the door shaft 30 in the parapet area.

If the window frame 2 is made of plastic, it may be combined with the associated window pane 1 to form a window module, that the window pane 1 along its respective outer edges 11, 12, 13 of the associated frame sections 21, 22, 23 of the window frame 2 (Fig. without permanent adhesion) is overmoulded. In the manufacture of the window frame 2 as a 2K-part, consisting of a softer plastic component disc seal can be made integral with the frame sections 21, 22, 23 of the window frame and molded.

In the embodiments described above, the window pane to be adjusted is always displaceable along a direction z, which-in relation to the state installed in a motor vehicle-essentially coincides with the vertical vehicle axle of a motor vehicle. The one described above with reference to FIGS Arrangement is by no means limited to such cases in which the window pane is adjustable only along a straight line or even more specifically only along a vehicle axle (namely the vertical vehicle axle). Rather, the adjustment of the window pane along curved paths should also be expressly included, so that the adjustment direction of the window pane changes locally along its adjustment path. The vertical vehicle axis z then corresponds to a Hauptverstellrichtung, corresponding to a lifting of the window pane in the associated window opening or a lowering of the window pane from the window opening. Such a raising or lowering of the window pane in the vertical direction z, however, can still be superimposed by movement components along other spatial directions.
