Vehicle door

0001The invention relates to a motor vehicle door with a door outer panel and a large cutout provided inside door panel, the partially covered by a support plate can be covered, according to the preamble of claim 1.

0002From DE 196 11 074 A1 is a so-called outboard double Bowden tube window known whose mechanical adjustment between the outer door panel and the window pane is arranged. The attachment of the Fühtungsschienen via Screw on the inner door panel which is crimped to the outer door panel. External windows have the advantage that they are very compact and the not restrict space between window and door lining, whereby a greater scope for the inside door trim yields. A disadvantage, however, that the connection of the construction principle of an outer window lifter with Advantages of a door module consisting of a plurality on a support plate preassembled and vorprüfbaren functional units, does not appear possible without further ado.

0003Such door modules are described in DE 195 09 282 A1 and DE 195 11 105 C1. Accordingly, the guide rails of the cable window lifter are suitable Attachment points connected to the support plate, which is obviously a connection of Windowpane allows only the manner of a so-called inner window lifter, wherein the window pane between the door outer panel and the window lifter is arranged. Inevitably, the design of the carrier plate without Addressing the needs of the window pane guide and thus the Window lifter done. The measures provided for in the inner door panel large cutouts will be covered by the respective carrier plate. In order to connect the to allow the window glass at the windows after the carrier plate assembly, stand in the support plate special mounting holes are available which - for example by Rubber cover - after completion of the assembly can be closed again.

0004The EP 0420617 B1 describes a door window cassette consisting essentially of a window frame and affixed thereto lateral guide channels for Window pane and an intermediate mounting plate. Directly on the Mounting plate are four individual cable guide pulleys and a drive unit mounted. A horizontally extending rod is with its ends to the vertically extending portions the guided around the pulleys rope loop attached. About the connecting bolt Rod is the window associated with the window. Thus, the Support plate an integral part of the window lifter is and must therefore precisely to the leadership needs of the window pane to be adjusted.

0005The invention has for its object, the generic motor vehicle door in such a way further, that the use of substrates with mechanical mounted thereon and / or electrical and / or electronic components in combination with outer window regulators is ensured. The invention is a constructively have simple structure and facilitate assembly of the motor vehicle door.

0006According to the invention the object is achieved by the characterizing features of Patent claim 1. Accordingly, the carrier plate is on the outer door panel facing side connected to a mounting rail which encloses the window pane and at least one guide rail of a Bowden cable window lifter slidably superimposed. By using this simple technical means creates a Combination of a carrier plate with an outer window while maintaining all the benefits of a comprehensive and accommodate most vorprüfbaren door module.

0007According to a first variant of the invention the mounting rail as a separate part executed via their ends and to the carrier plate through screws, rivets, welding or adhesive bonding. As far as different technical requirements for the Support plate and the mounting rail using different materials suggest, Of course this is counteracted by nothing.

0008A second variant of the invention, the mounting rail in one piece into the carrier plate to integrate. The integration of the mounting rail in the carrier plate lends itself particular, if this is to be executed as a plastic part or cast part, because modern injection molding techniques and the cost-effective production of complex parts in allow high quality. Another advantage of the one-piece design is derived from the Prevention of tolerance variations and a mounting step for connecting the two parts.

0009An integrally connected to the support plate mounting rail can also based a sheet metal part are obtained if the region of the guide rail while maintaining its peripheral connections punched to the carrier plate and by drawing in Richting the wet space of the vehicle door is issued.

0010Appears to be advantageous, the integration of the cable drum housing in the mounting rail, whereby a reduction in components is achieved, and the mounting of the drive unit to the mounting rail. In addition, a pre-assembly of the entire Window system are provided on the mounting rail, if a separate, with the carrier plate to be connected to the mounting rail is used.

0011To simplify the assembly to be fastened in the door body Functional components, these components should ebenfals to the mounting rail Store displaced. This can in particular, done that Functional components (eg door lock and outside handle holder) with the displaced Guide rail of the window lifter or - at a doppelsträgigen Bowden tube window for a driver or front passenger door - with the B-pillar side guide rail get connected. Takes place by the positioning of the guide rail at the same time Positioning its associated functional components. These compounds may be made for example by carriers, the corresponding to the Components attached or are integrally formed.

0012Another Vorsugsvariante of the invention provides that the use of a double Bowden tube window lifter which the cable drum-containing arranged drive unit outside the space between the guide rails is. Furthermore, the drive unit of the facing guide rail in the end-side deflection of the rope a rope output which the drive unit faces, and a cable exit which faces the other guide rail. On Such a configuration ensures that the moveable guide rails easily from their Transport position can be moved to the operative position without the move along window drive or electrical connectors between the motor and / or to interrupt an electronic control device. This ensures a comprehensive Vorprüfbarkeit of the door module and the risk of mistakes reduced.

0013The invention will be reference to an embodiment and the illustrated Figures explained in greater detail. Show it:<dl tsize="8"><dt>figure 1</dt><dd>Side view of the wet space side of a carrier plate with pre Functional components prior to their incorporation into the door body;</dd><dt>figure 2</dt><dd>schematic cross section of a vehicle door in accordance with a module equipped Figure 1;</dd><dt>figure 3</dt><dd>View of a door body with a large cutout in the inner door panel for Equipment with a door module according to FIG. 1</dd></dl>

0014The door body 1 shown in Figure 3 has a large cutout 101 in The inner door panel 11, which of the struts 102, 103 to increase the stiffness of the Door body 1 is traversed. An additional reinforcing member 104 serving as Seiteneinfahrschutz. The large segment 101 is particularly well suited for assembly the vehicle door with a so-called door module whose support plate 2 the cut 101 at least partially covers and carries the essential functional components.

0015Figure 1 shows such a door module, which, inter alia, with an external, ie arranged between the window pane 8 and the door outer panel 10, doppelstängigen Bowden tube window and a lock 4 is equipped. By means of the schematic Cross-section of Figure 2, of all the important components of the door module, regardless of their actual location in the vehicle door cuts, can ease of understanding be achieved in terms of the structure of the invention.

0016A substantially horizontal and parallel to the support plate 2 and the outer door panel 10 extending mounting rail 20 engages on the wet space A window pane 8 and is firmly connected with their ends on the fixing points 20a to the support plate. 2 Store in the mounting rail 20 by means of holding elements 30a, 30b, the guide rails 3a, 3b of the displaceable double-strand cable window lifter, wherein the one Guide rail 3a is engaged with the lock 4 and the outside handle holder 5 in connection. The Representation of Figure 2 shows the functional positions of windows and lock 4. In the (Not shown) transport and installation position, the guide rails 3a, 3b and the associated functional components (lock 4 and the outside handle holder 5) applicable in Direction of the drive unit 202 moved that a problem-free threading Window lifter and the lock 4 is possible. Only after the carrier plate 2 at Inner door panel 11 has been attached, the guide rail 3a to the lock 4 is in the displaced operating position, so that the lock 4 to the intended location of the Door body can be attached.

0017The connection between the guide rail 3a and the lock 4 can on different ways are prepared. For example - as shown in Figure 1 indicated - the lock 4 via a lock carrier 40 to the outside handle holder 5 be connected, in turn, on the fastening points 51 to the Fühtungsschiene 3a is mounted. On the other hand, it is also possible for the lock 4 on its Lock carrier 40 directly - or as indicated in Figure 2 - via another carrier 40a from lock 4 and the outside handle holder 5 existing unit on the guide rail 3a fasten.

0018The retaining elements shown in the figure 1 30a, 30b serve only the description the basic structure of the invention; In principle, any connection between the Mounting rail 2 and at least one guide rail 3a, 3b are used, which represents a displaceable mounting such that the relevant guide rail 3a, 3b be moved from a transport or mounting position into the operating position can. These are also useful in the mounting rail 2 integrated sliding guides, in engage paßfähige guide elements of the guide rails 3a, 3b.

0019Provided that the mounting rail 2 is to be carried out as a cast or injection molded part, may at least the cable drum housing 200 in which the cable drum 201 superimposed integrally in the Mounting rail 20 are integrated. This saves a separate Cable drum housing. In particular, when the required displacement between the transport / mounting position and the operating position of the guide rails 3a, 3b of a double Bowden tube window lifter is relatively long, should the Drive unit 202 with the pulley 201 outside the space between the Guide rails 3a, 3b, expediently on the castle 4 side away be the carrier plate 2 arranged.

0020To minimize deflections in the Bowden tubes and thus to minimize Friction losses are the cable outlets in the deflection of the drive unit 200, 201, 202 facing the guide rail 3a oppositely directed, said about the Bowden tube 32b to the cable drum 201 affiliated cable output of the drive unit faces, while the other cable exit of the guide rail 3b facing and with the lower cable exit is directly through the Bowden tube 32ab connected. by means of the Bowden tube 32a between the top Wire exit the guide rail 3a and the Cable drum 201 is the cable loop and thus the power flow in the closed windows.

0021For fixing the window pane 8 are at each guide rail 3a, 3b driver 31a, 31b, which are fixed to the cable loop and on actuation of the Window lifter be raised or lowered along the guide rails 3a, 3b.

0022The selected for the exemplary embodiment the carrier plate 2 is a double Plastic part is produced on the basis of the blow molding. For stiffening the carrier plate 2 are stiffening portions 21a, 21b provided, in which the two Walls are interconnected. One or more cavities can contribute Lodging mechanical or electrical components or for guiding cables and linkages serve. Moreover, a closed cavity as act resonance chamber for a speaker.

0023In the upper part of the support plate 2 a grip 22 is integrated, in which the door layered; of the Bowden cable 220, the operating force is transmitted to the lock. 4

0024On the dry space side B carries the support plate 2 a side airbag 7 which in itself If necessary, unfolded by a predetermined breaking point (not shown) the door inside trim.

0025Since the support plate 2 the cutout 101 covers only partially in the inner door panel 11, it is for separating wet space A and dry space B requires at least the remaining open area covered by suitable means. This can, for example, done by sticking a correspondingly cut film.
