DETAILED DESCRIPTION

[0040] FIG. 1 shows a vehicle door with a view to a wet-space side of a carrier component in the form of a door module carrier 1. The vehicle door comprises a door inner skin TI, for example in the form of a door inner panel. In a manner known per se, the door inner skin TI together with a door outer skin not shown in FIG. 3 defines a wet space NR (cf. FIGS. 1A and 2A), in which parts of a window regulator are arranged in order to be able to lift and lower a window pane of the vehicle door. The window pane in particular can be lowered into this wet space NR.

[0041] For separating the wet space NR from a dry space TR facing the vehicle interior the door module carrier 1 is provided. The door module carrier 1 closes an opening provided at the door inner skin TI, via which in particular the functional components of the window regulator can be positioned in the wet space NR. On a wet-space side facing the wet space NR the door module carrier 1 therefor has a carrier surface 10 on which functional components of the window regulator are provided. These include in particular two longitudinally extending guide rails 3A and 3B, which in the case of the vehicle door 1 of FIG. 3 are fixed to the carrier surface 10 as separate components. The guide rails 3A and 3B serve to define a guideway for the window pane to be adjusted. Furthermore, a window regulator drive 2 is fixed to the door module carrier 1. Moisture-sensitive components of the window regulator drive 2 are located on a dry-space side of the door module carrier 1 facing away from the wet space NR. A cable drum of the window regulator drive 2 for driving a Bowden cable for the adjustment of the window pane in turn is provided on the carrier surface 10 on the wet-space side. The door module carrier 1 furthermore carries a door lock 6 and a speaker 4 as further functional components.

[0042] To utilize a volume provided within the wet space NR for a defined resonance space for the speaker 4, a design variant of FIGS. 1 and 1A provides for the vehicle door of FIG. 3 to provide a resonance body component 5 on the wet-space side of the door module carrier 1. This resonance body component 5 forms a so-called “soundbox”, which on the wet-space side of the door module carrier 1 surrounds the speaker 4 received in a speaker opening of the door module carrier 1 like a housing. In this way, the resonance body component 5 defines a closed resonance space 50 of defined size within the wet space NR for the speaker 4. With a body portion protruding in the direction of the door outer skin and an opposite carrier portion of the door module carrier 1, the resonance body component 5 of FIGS. 1 and 1A defines a cavity or clearance as a resonance space 50 into which the speaker 4 protrudes.

[0043] In FIGS. 1 and 1A the carrier portion of the door module carrier 1 located opposite the protruding body portion of the resonance body component 5 forms a speaker mounting surface 14 with the speaker opening for the speaker 4, which is set back in the direction of the door interior space with respect to the carrier surface 10 of the door module carrier 1 carrying the guide rails 3A and 3B. In this way, the resonance body component 5 utilizes a setback present on the door module carrier 1 with respect to the carrier surface 10 in order to define the closed resonance space 50, without protruding from the carrier surface 10 and in particular the guide rails 3A and 3B provided thereon in the direction of the door outer skin. The resonance body for the speaker 4 formed with the resonance body component 5 in the direction of the door outer skin thus does not impair the adjustability of a window pane S guided along the guide rails 3A, 3B within the wet space NR.

[0044] In a development according to FIGS. 2 and 2A, the resonance body component 5 constitutes a large-surface component which in the mounted state covers a large part of the wet-space side of the door module carrier 1. For example, there is provided a coverage of more than 50% by the resonance body component 5. In this way, the resonance body component 5 of FIGS. 2 and 2A in conjunction with the opposite carrier portions of the door module carrier 1 forms a resonance space 50 of comparatively large volume. For example, the volume of the resonance space 50 can be more than 20%, in particular more than 30% or more than 35% of the total volume of the wet space NR. Nevertheless, the resonance body component 5 of FIGS. 2 and 2A is circumferentially connected to the door module carrier 1 at its edge defining the outer contour of the resonance body component 5.

[0045] To create the resonance space 50 of such a comparatively large volume, additional functions are integrated into the resonance body component 5 of FIGS. 2 and 2A. On a body portion protruding in the direction of the door outer skin with respect to the carrier surface 10 of the door module carrier 1, the resonance body component 5 has a large-surface rail carrier surface 53 on which the guide rails 3A, 3B for the window regulator of the vehicle door are provided. The guide rails 3A, 3B here can be fixed to the rail carrier surface 53 as separate components. Alternatively, at least one of the guide rails 3A, 3B on the rail carrier surface 53 can be formed as an integral part of the resonance body component 5 and hence can be formed by the resonance body component 5.

[0046] In the design variant of FIGS. 2 and 2A, the resonance body component 5 furthermore forms a lock carrier surface 56 laterally protruding from the rail carrier surface 53, to which the door lock 6 is fixed.

[0047] In addition, a drive carrier surface 52 is formed by the resonance body component 5. The window regulator drive 2 for the window regulator is fixed to this drive carrier surface 52 so that the components of the window regulator drive 2 to be protected from moisture are arranged within the resonance space 50 formed between the carrier component 1 and the resonance body component 5.

[0048] In the design variant of FIGS. 2 and 2A, the door module carrier 1 chiefly performs the wet/dry space separation, while via the resonance body component 5 a plurality of functional components are properly positioned and held within the vehicle door and with respect to the door module carrier 1.

[0049] For mounting the vehicle door of FIGS. 2 and 2A it can be provided for example that initially the resonance body component 5 is mounted to the carrier surface 10 of the door module carrier 1, possibly before or after functional components, such as the guide rails 3A, 3B and the door lock 6, have been mounted to the resonance body component, and before or after the speaker 4 has been arranged in the speaker opening of the door module carrier 1. Subsequently, the door module carrier 1 with the resonance body component 5 held at the carrier surface 10 is positioned within the wet space NR via the opening in the door inner skin TI, and the door module carrier 1 is fixed to the door inner skin TI. As a result, the closed resonance space 50 defined with the resonance body component 5 then is present within the wet space NR, and the wet space NR is separated from the dry space TR via the door module carrier 1 sealingly resting against the door inner skin TI.

[0050] In particular in the design variant of FIGS. 2 and 2A with a comparatively large-surface resonance body component 5, on which in particular the guide rails 3A and 3B of the window regulator are provided, it is not only easily possible to provide a comparatively large resonance space 50 for the speaker 4 within the vehicle door. Rather, an effective thermal and/or acoustic insulation within the vehicle door is also realized via the resonance body component 5.
