Description

DOOR FOR MOTOR VEHICLE DESCRIPTION The invention relates to a motor vehicle door according to the preamble of patent claim 1 and is preferably designed in a modular construction. A vehicle door of this type is known from DE-41 12 261 Al, which describes a motor vehicle door with an external door wall and an internal door wall, on which a receptacle part is screwed. (module support), which supports an electric window lifter, and a cable tree with several plug connections. In the assembled state, the receptacle part covers the largest area of the opening in the inner door wall. In the upper area of the interior of the door, between the edges of the inner door wall and the part of the receptacle is an assembly opening, which is to allow the window lifter to be raised above the window lift rail connected to the bottom edge of the window panel. Even with this solution, a separate seal is necessary to seal the internal door space of the water filtration, if it is desired to avoid costly waterproof designs for electrical assemblies (eg electric motor) and plug connections. DE 35 29 660 C2 describes a cable tree for a motor vehicle door, which is mounted on a support plate of the internal door frame, which seals the opening in the inner door panel substantially against the water. Only in the lower area of the support plate two cable guides are provided through which an electric motor as well as the central lock will be provided with power. The sealing of the cable guides is not provided. Another variation begins with a door with an internal door panel, which has some assembly openings. The cable tree is mounted with its plug connections on the internal door frame. Yet, these technical solutions have the disadvantages already described with respect to the need for a separate seal measurement or expensive moisture area designs for the electrical components. From DE 29 28 685 Cl, a device for fixing a window lift base plate on the inner wall of a vehicle door is known, wherein a part of the outer circumference of the window lift base plate is connected. to a flexible, extruded sealing profile which, in the assembled state of the window lifter, seals the inner door wall of the vehicle in a sealed manner providing a depression corresponding to the profile of the elevator base plate. window. With the fixing of the window lift base plate on the inner door wall of the vehicle door, the depression 14 is actually closed, but additional handles are required to adjust the window lift through the various openings separated from depression. From JP 6-144011 (A) a water-tight construction for a motor vehicle door is known, wherein the inner wall of the door is provided with a depression. With this device a connection cover is fixed from the outside of the closed support plate with the sealing material mounted therebetween. Only after fastening, other connecting bars are the openings covered inside the internal door panel, which remain after the connecting cover has been fixed. CA-A 1 332 620 discloses a vehicle door with an external door wall, an internal door wall, and a door module that can be inserted into the inner wall. The door module supports all the functional units of the vehicle door. An internal door frame is fixed on the door module. In one embodiment, a dry space is formed within the door module and contains a door opener, an electrical control unit and a loudspeaker. The dry space is formed from a suitably hollow area of the door module, which is not broken, an area of the internal door frame opposite thereto and suitable sealing faces between the door module and the inner door frame. A locally restricted assembly opening in the door module or in the inner door wall, which allows the window lifter to be connected to a window pane, is not provided. The object of the invention is to develop a motor vehicle door with locally constrained assembly openings for the seamless assembly of a window pane on a window lifter, which without additional separate sealing means for these assembly openings allows the door body is divided into an external wet space and an internal dry space with a simple assembly and which allows the modular construction of the vehicle door. According to the invention, this is achieved through a motor vehicle door with the features of claim 1 of the patent. The claims provide preferred variations of the invention. Accordingly, at least one of the assembly openings is closed through an operating unit, for example, a manually operated unit for closing the door or a side air bag or a unit for continuing or distributing the energy of drive or signals or other operating unit. According to the present invention, an assembly opening is provided which, in any case, for assembling a window pane on a window lifter, is not closed by an otherwise useless cover, but is closed in a way that saves space and cost effectively through an operating unit, which is provided in any case in the door. In this way, an existing assembly opening is used in a further form, primarily to support an operating unit. The inner door panel preferably has a relatively large cutting section, which can be sealed to water through a module holder. The module support has, in turn, assembly openings which serve, for example, to produce the connection of a window lifter with the lower edge. The function parts have sufficient mechanical stability to make them suitable to withstand conditioned cushion and absorption forces to the required degree. When several operating units are used, they can be connected together, for example, in order to support a component part of the joint function unit. All electrical or electronic components and component parts are assembled in the dry space of the door body, so that designs that are protected against moisture can be avoided. The invention will now be explained in more detail with reference to the embodiments and drawings illustrated, in which: Figure la is a diagrammatic view of a vehicle door with a large cutting section in the inner door panel; Figure Ib shows a module support with two assembly openings as well as the electric window lifter and the central locking unit prefixed thereon; Figure is a diagrammatic illustration of two functional units (manual operation unit for closing the door and side air bag); Figure Id shows a module support with functional units fixed therein and located in the transport position; Figure shows a vehicle door in the finished assembled state where all the component parts are located in functional positions; Figure 1 is a perspective view of the vehicle door in a modular structure; Figure 2a shows a vehicle door with a practical and completely closed inner door cover, only with two assembly openings; and Figure 2b is a diagrammatic illustration of two functional units (manual operation unit for door closure and side air bag). The invention can be used with particular advantage when the vehicle door has a medullar structure according to Figures a to Ib. Figure 1 shows a diagrammatic view of the door body, consisting of an internal door plate Ib with a large door cutting section (opening 10) through which the external door panel can be seen, and a frame of door 11 provided for guiding the window pane 2. Fastening elements 20 are attached to the lower edge of the window pane for connection to the mechanism of the window elevator 31. To close the opening 10 in the inner door panel Ib is located a module support 3 on which a window lifter mechanism is mounted. Its lever arms 31b, 31d are mounted oscillatingly in the articulated joint 311 and are connected through sliding oscillating joints to a lifting rail 31a. While the opposite end of a lever arm 31d is guided on the guide rail 31e, the second end of the other lever arm, which is mounted on the rotary shaft 310, connected to the module support 3, is formed as a toothed segment 31c and engages with a toothed element of the motorized impeller 31f. While the window lifter mechanism 31 is mounted on the side facing the outer door cover 1, the motorized driver 31f is located on the other side facing the internal door frame. In this way, the electrical / electronic components are in the so-called dry chamber of the door body. The transfer of force is through a drive shaft 31ff projecting through the module support 3 and sealing against the water inlet. In the upper area of the module support 3 there are two assembly openings 3a, 3b, through which the connection is made between the elevator rail 31a and the fixing elements 20 of the window glass 2. These assembly openings 3a, 3b are now not closed in the usual way through a sheet or a separate cover or the like, to protect the internal door space (dry chamber) from moisture, but rather the closing of the assembly openings is provided according to the invention through functional units, which are provided in any case in the door.

Such functional units can be, for example, manual operating means 5, for the door lock, a side air bag 6, an electrical drive unit or structural group for sending power or drive signals. Naturally, the invention is not restricted only to the closure of such assembly openings that are located to a window coil of transverse arm or window lifter of another type. The invention relates to closing assembly openings of any type through one or more functional units. On its circumference, the module support 3 supports a seal 30, which is to provide a water tight seal together with the inner door panel. In addition, a closure unit 4 is mounted on the module support 3. It has a coupling point 41 for a Bowden rod or cable connection for operation. The locking bar 40 projects through the assembly opening 3b from the closure 4 on the wet space side and has access for manual operation on the dry space side with its upper free end. The present embodiment provides, in accordance with the diagrammatic illustration of Figure 1, a manual operation unit 5 for a door lock, as well as a side airbag 6 as functional units for closing the assembly openings 3a, 3b. According to this, the operation unit 5 basically consists of an armature of support 50, which supports a seal 51, and an operation handle 52, where the latter is connected after the assembly through the link 410 (or Bowden cable 410) at the coupling point 41 with the door lock 4. The functional unit 6 basically consists of the support shell 60 with the seal 61 and the air bag module 62. In addition, three openings are provided 63, 64, 65 to pass through component parts, which will likewise be sealed or at least protected against water spraying. In this way, the opening 63 serves to pass through the bar link 410 from the handle 52 to the door lock 4 mounted in the wet space. A cable 7 is passed through the opening 64, which also provides the closure 4 and thus guarantees the operation of the central closure. The opening 65 only serves to pass through the closure bar 40 from the dry chamber to the wet chamber. The support protections 50, 60 and the modular support 3, are thus formed stable, so that they can transfer (particularly in the area 300) the support forces produced. The danger of damage through an accident or the degree of seriousness of such damage can be reduced.

Figure Id shows the functional units 5, 6 in a pre-assembled transport condition on the module support 3, where the assembly openings 3a, 3b are only covered so that a problem-free assembly of the elevator is presented. window 31. The illustrated module has a high degree of integration and is suitable to allow considerable improvements with respect to the assembly sequence and thus also a cost saving. According to the invention, the functional units 5, 6 have a double function; in addition to its actual useful purpose, it serves to close the assembly openings 3a, 3b. In this way, separate measurements for sealing are saved. After completing the assembly of all the structural groups and functional units 5, 6 in the door body, they are located in the operating position shown in Figure 1. The perspective illustration of the vehicle door in the modular structure according to Figure lf shows the state of the vehicle door after the connection of the window lifter mechanism 31 to the window pane 2 and directly before closing the openings 3a, 3b through the operating units 5, 6. Furthermore, it can be seen clearly that the window lifting mechanism 31 lies in the wet space between the outer door cover a and the inner door cover Ib, while that the drive unit 31f is mounted in the dry space between the inner door cover Ib and the inner door frame (not shown). Figure 2a shows a door body with a practical and completely closed internal door cover l'b. Only two assembly openings 3 'a, 3'b are formed to fix the window lifter in the inner door cover l'' b. The contours of the assembly openings 3 'a, 3'b and the contours of the functional units 5, 6 provided for the closure coincide with each other. With respect to the spatial conditions of the two functional units 5, 6 through the bar link 410, these are preferably supplied together for the assembly. For the rest of the explanations made for the Figures to him, apply in the present.
