Description

[0001] The invention relates to a frame door of a motor vehicle, comprising a door body, a guide frame with at least one lateral frame rail and an upper frame rail, and a door module with a window regulator arranged thereon for moving a window pane from an open position to a closed position. It further relates to a door module for such a frame door, comprising two parallel guide rails and sliding guides mounted thereon.

[0002] A vehicle door, which can be designed as a frameless or framed door, typically comprises a door body with a frame-like door structure (inner door section) and an outer door panel forming the outer skin, as well as optionally an inner door panel or inner door trim. The inner door section, connected to the outer door panel, typically has two opposing, spaced-apart lateral frame sections and a door sill connecting them (sill section), as well as optionally a lower frame section.

[0003] The following information pertains to the spatial directions in a motor vehicle's coordinate system (vehicle coordinate system) regarding the typical position or location of a vehicle door (side door) relative to the vehicle's body. The abscissa (X-axis) is oriented along the vehicle's longitudinal direction, the ordinate (Y-axis) along the vehicle's transverse direction, and the application axis (Z-axis) along the vehicle's height.

[0004] The door sill, oriented in the longitudinal direction of the vehicle (X-direction in the vehicle coordinate system), together with the lateral frame sections oriented in the direction of the vehicle height (Z-direction in the vehicle coordinate system) and with a frame section extending in the X-direction that connects these sections to the underside of the door, defines a frame cutout in the inner door part (door shell). This frame or module cutout is, in the assembled state of the vehicle door, at least partially, and preferably completely, covered by a plate-like or plate-shaped door module carrier of a door module.

[0005] The door module carrier can be an injection-molded part made of plastic, particularly fiber-reinforced plastic. Various functional components of the vehicle door, especially components of a window regulator (a window regulator assembly), can be pre-mounted on the door module carrier. Guide rails typical of such a window regulator can be integrated into the door module carrier or mounted on it as separately supplied components, for example, made of metal. The pre-assembled door module carrier, or the door module itself, also serves, in particular, to separate a wet compartment formed between the outer door panel and the door module from a dry compartment formed between the door module (door module carrier) and the inner door panel or the interior door trim of the vehicle door, especially for moisture-sensitive functional components of the door module.

[0006] In a door module with a guide rail (window regulator guide rail) mounted on or integrated into its support plate (door module carrier), which projects upwards beyond the door module carrier in the Z-direction with a section of rail known as a rail overhang, the door module carrier or the door module itself is typically attached to the frame-like inner door part (door frame) by means of a number of screws or connecting elements in the form of bayonet-type plug-and-twist connectors. The guide rail can also be additionally fastened to the door sill of the inner door part (door frame) in the area of ​​its overhang.

[0007] Unlike a frameless vehicle door, a framed door has a guide frame above the door sill of the door body, typically with two lateral frame rails (A- and B-side frame rails) and an upper frame rail on the vehicle roof side. A sealing element is typically provided on the guide frame or in the area of ​​the frame rails to ensure sufficient sealing of the window pane as it moves from an open position within the door body, via the window channel of the guide frame, to the closed position.

[0008] If the guide frame is designed with U-shaped frame rails in the profile cross-section, then secure pane guidance and sufficient sealing of the window pane in its closed position are generally ensured over time (lifespan) and even after numerous adjustment cycles of the window pane from an open to a closed position. However, with such a guide frame, flush glazing or a flush-glazing look is practically impossible to achieve, especially since one leg of the U-shaped frame rails protrudes visibly from the outside of the window pane.

[0009] If, however, the guide frame of the frame door is designed for a flush-glazing look, especially without a visible rail or frame leg on the outside of the pane, then sufficient sealing of the window pane in or on the guide frame, especially over time (lifespan) or after a large number of adjustment cycles of the window pane into the closed position, can only be achieved with undesirably high (cost) effort.

[0010] The invention is based on the objective of providing a (motor vehicle) frame door with a door module and a window regulator mounted thereon, in which, while simultaneously offering a low-effort flush-glazing appearance, a reliable seal of the window pane against a sealing element, in particular against a roof-side and / or side sealing elements, preferably at least against the B-pillar-side sealing element, is ensured over time and even after numerous adjustment cycles of the window pane from an open to a closed position. Furthermore, a particularly suitable door module for such a motor vehicle frame door is to be specified.

[0011] With regard to the frame door of a motor vehicle, the aforementioned problem is solved according to the invention by the features of claim 1 and with regard to the door module by the features of claim 9. Advantageous embodiments and further developments are the subject of the dependent claims.

[0012] The frame door intended for a motor vehicle, in particular a frame side door, comprises a door body and a door module with a pre-installed window regulator. The door body has a door sill with a window recess and a guide frame with at least one lateral frame rail and an upper frame rail on the vehicle roof side. A sealing element is arranged on the guide frame in the area of ​​each frame rail.

[0013] The door module has a door module carrier on which two parallel guide rails for the window regulator are arranged. Each guide rail has a projection extending beyond the upper surface of the door module carrier, which is guided against the door sill or partially overlaps it. Sliders, connected or coupled to a window pane, are slidably guided along the guide rails and are coupled to a drive mechanism, particularly an electric motor, for adjusting the window pane between an open and a closed position. A stop element is provided in the area of ​​each guide rail projection, against which the sliders are guided when the window pane is in the closed position.

[0014] In other words, both rail sliders strike the stop elements when the window pane is moved into the closed position. This ensures that the window pane always rests in a consistently advantageous position against the sealing elements, preventing tilting and avoiding unwanted gaps along the frame rails, particularly in the area of ​​a decorative trim panel on the B-pillar side and / or the frame rail there, with sufficient sealing effect against the sealing elements of the guide frame.

[0015] The guide rails are particularly advantageously integrated into the door module carrier, especially the plate-shaped one, and preferably formed from the carrier material. The respective stop element is expediently integrated into the rail projection of the guide rails or molded onto it or onto the rail head of the corresponding guide rail.

[0016] According to a suitable further development, the respective rail projection of the guide rails is attached to the door sill by means of a screw element. It is particularly advantageous to provide the respective screw element on the side of the stop element facing away from the respective rail slider, preferably directly next to the stop element.

[0017] In a suitable embodiment, each screw element has a threaded section on both sides of a locking or contact section, which is particularly disc-shaped. At least one of the threaded sections has an actuating engagement for a tool. The screw elements are suitable for adjusting the track of the rail sliders such that the window pane, especially its upper edge, is inclined inwards towards the vehicle when moving along the track into the closed position and is moved or guided outwards towards the vehicle upon reaching the sealing element of the upper frame rail. In other words, the window pane is pressed or pushed into a constrained position by the sealing pressure in the upper frame rail."Vehicle interior" refers to the Y-direction (vehicle transverse direction) oriented towards the interior of the motor vehicle or the inside of the frame door, and "vehicle exterior" refers to the opposite Y-direction towards the outside of the frame door or the motor vehicle.

[0018] Another embodiment provides for a deflection element, in particular a rotatably mounted pulley, for a traction cable coupled to the door actuator on the rail sections of the guide rails that project above the door sill. Further deflection elements are preferably provided at the rail end or rail foot of the respective guide rail opposite the rail section. By means of the deflection elements, the traction cable coupled to the actuator is guided or deflected into a cable path parallel to the respective guide rail.

[0019] In a practical embodiment, each rail slider comprises a base body with a rail grip for coupling to the associated guide rail and a clamping leg. This clamping leg is connected to the base body, in particular by means of a clamping screw, for clamping the window pane. By means of a pane hole in the window pane aligned with a through-hole in the rail slider, and the clamping screw inserted through the through-hole and the pane hole into the clamping leg of the rail slider, the desired alignment of the window pane to the guide frame or to a (B-pillar-side) decorative trim and / or fine-tuning of the pane's passage through the door sill's window recess can be easily and reliably achieved.

[0020] The door module, designed and configured for a vehicle door, comprises a door module carrier with guide rails for a window regulator mounted on it. A slider coupled to a drive unit, preferably an electric motor, is guided movably on each of the (preferably two parallel) guide rails, with each guide rail having a projection extending beyond the top of the door module carrier. A stop element for the sliders is provided in the area of ​​the projection on each guide rail.

[0021] A screw element for adjusting the inclination of the respective guide rails is conveniently provided on the rail projection. This allows for both the preload of the window pane and the desired or precise passage of the pane through the door frame.

[0022] Exemplary embodiments of the invention are explained in more detail below with reference to a drawing. The drawing shows: Fig. 1 in a top view a frame door with a door body and with a guide frame as well as with a door module with (pre-)assembled window lifter with parallel guide rails and rail sliders guided thereon in a (lower) position retracted into the door body, representing an open position of a window pane and in a position moved against stop elements, representing a closed position, Fig. 2 in an enlarged section from Fig. 1 the upper area of ​​the door module with stop elements for the rail gliders provided on a rail projection of the respective guide rails as well as with screw elements for rail adjustment or for adjusting a disc preload, Fig. 3 in a perspective view, an enlarged section of Fig. 2 with one of the stop elements and the screw element on the rail overhang of the corresponding guide rail, Fig. 4 a sectional view along line IV-IV in Fig. 2, Fig. 5 in a sectional view along a line VV in Fig. 1 the course of the window pane pre-tensioned towards the vehicle interior and the window pane deflected towards the vehicle exterior at a sealing element of an upper frame rail in flush-glazing look, and Fig. 6 a sectional view along line VI-VI in Fig. 1 with a window pane in flush-glazing look, adjacent to a sealing element of a B-side frame rail of the guide frame.

[0023] Corresponding parts and sizes are marked with the same reference symbols in all figures.

[0024] The following information pertains to the spatial directions in a vehicle coordinate system, in which the X-axis is oriented along the longitudinal direction of the vehicle, the Y-axis along the transverse direction of the vehicle, and the Z-axis along the vehicle height.

[0025] Fig. Figure 1 shows a frame door 1 of a motor vehicle, with a door body 2 without an outer door panel, showing a frame-shaped door structure 2a, a guide frame 3, and a door module 4 attached to the door body 2. The door module 4 has a plate-shaped door module support 5. Functional elements of a window regulator 6 are mounted on the door module support 5. This regulator is a so-called two-rail (cable) window regulator with two parallel guide rails 7. These guide rails are mounted on the door module support 5 on a wet-room side (front of the support) of the door module 4, together with deflection elements 8 (upper and lower) in the form of rotatably mounted cable pulleys provided at the ends of the rails. A slider 9 is guided along each of the guide rails 7 so that it can slide along the longitudinal direction of the rail.

[0026] A window pane 10 is attached to the rail slider 9 and is adjustable between an open and a closed position. For this purpose, an actuator 11, preferably electric, is provided. The electric motor of the actuator, which is located on the rear of the support or drying chamber side of the door module 4, drives a cable drum, also located on the rear of the drying chamber or support, particularly via a gearbox. A pull cable 12 is wound onto the cable drum with several turns. This pull cable is guided over the deflection elements 8 and connected to the rail sliders 9. Depending on the drive direction of the actuator 11, one section of the pull cable 12 is wound up and the other section is unwound, thereby adjusting the window pane 10, which is held on the rail sliders 9, between the open and closed positions.

[0027] The door body 2 has a door sill 13 with a window channel 14, over which the window pane 10 is moved from the door body 2 into the closed position, resting against the guide frame 3. The guide frame 3 has an upper, vehicle roof-side frame rail 3a and side frame rails 3b, 3c, which are hereinafter also referred to as the B-pillar-side frame rail 3b and the A-pillar-side frame rail 3c, respectively. A sealing element 15 is arranged on the guide frame 3 in the area of ​​each frame rail 3a, 3b, 3c. A decorative trim 3d is provided in the area of ​​the B-pillar-side frame rail 3b.

[0028] The door sill 13, as the upper frame part, and (unspecified) lateral frame sections, as well as a connecting (unspecified) (lower) frame section of the door frame 2a of the door body 3, define a non-visible frame cutout which, in the installed state of the frame door 1, is covered by the door module 4 mounted on the door body 3 or on its door frame 2a. The door module 4 or the door module carrier 5 is attached to the door body 3 or on its door frame 2a by means of connecting elements 16 distributed around its circumference, preferably in the form of plug-and-turn fasteners.

[0029] As in connection with the Fig. 2 and Fig. As is relatively clearly evident in Figure 3, the guide rails 7 have an (upper) rail section 7a, hereinafter referred to as the rail projection, which projects beyond the upper surface or upper edge 17 of the door module support 5. In the assembly state shown, the rail projection 7a, which extends beyond the upper edge 17 of the door module support 5 in the Z-direction, rests against the door sill 13 of the door body 2 and is screwed there. A stop element 18 is provided on the rail projection 7a, or in the area of ​​the rail projection 7a of each of the guide rails 7. The respective stop element 18 is preferably formed on or integrated into the rail projection 7a of the respective guide rails 7 and projects at least slightly outwards in the Y-direction towards the vehicle.

[0030] The stop elements 18 ensure that the corresponding rail slider 9 reliably stops in a predetermined or specifically set position. This stops the further movement of the window pane 10 along its adjustment path defined by the guide rails 7 when the window pane 10 enters the closed position along the frame rails 3b, 3c into the upper frame rail 3a of the guide frame 3.

[0031] The stop element 18 is suitably formed as a rectangular, box-like contour raised in the Y-direction, made from the same material as the guide rail 7 or the door module carrier 5. The stop elements 18 can also be adjustable or designed as an additional part. The stop elements 18 prevent the window pane 10 from rotating in its closed position and ensure its parallel end position with the decorative panel 9c.

[0032] By means of the quasi-synchronous striking of the rail sliders 9 against the two stop elements 18 spaced apart from each other - according to the distance between the guide rails 7 or their rail projections 7a - tilting of the vehicle window 10, for example about a pivot axis oriented in the Y direction or normal to the XZ plane, is avoided and a reliable seal on the guide frame 3, in particular along the B-pillar side frame rail 3b, is ensured.

[0033] Each rail slider 9 has a base body 9a and a clamping leg 9b ( Fig. 1) on. By means of a screw 9c ( Fig. 1) The clamping leg 9b, which passes through a through-opening 9d of the base body 9a and a corresponding opening in the window pane 10, is screwed to the base body 9a with a corresponding section of the window pane 10 inserted and clamped in place. The through-opening 9d of the base body 9a has an inner diameter larger than the thread diameter of the screw 9c. This allows for adjustment of the relative position between the rail slider 9 and the window pane 10 clamped in it. By means of the pane hole in the window pane 10, which is aligned with the through-opening 9d of the rail slider 9 or its base body 9a, the parallel alignment of the window pane 10, especially in the X and / or Z direction, to the guide frame 3 or the decorative cover 3c can be easily and reliably achieved.

[0034] As in connection with Fig. As can be seen in Figure 4, the rail projection 7a of the respective guide rail 7 has a screw boss 19. The screw boss 19 is integrally formed with the rail projection 7a of the respective guide rail 7 or formed from the material of the door module carrier 5 and is raised in the Y-direction towards the outside of the vehicle. A screw element 20 is received in the screw boss 19, by means of which the respective rail projection 7a of the corresponding guide rail 7 is screw-fastened to the door sill 13, preferably adjustable in the Y-direction.

[0035] The respective screw element 20 is located on the side of the stop element 18 facing away from the respective rail slider 9 and directly adjacent to the stop element 18. Each screw element 20 has a threaded section 20b, 20c on both sides of a disc-like locking or contact section 20a. At least one of the threaded sections 20b has an actuating engagement 20d for a tool. The respective screw element 20 on the rail projection 7a serves to adjust the inclination of the respective guide rail 7 or to pre-tension the window pane 10. This allows the pre-tension of the window pane 10 to be adjusted. Furthermore, its precise, finely adjustable pane passage through the pane recess 14 of the door sill 13 can be adjusted.

[0036] As in connection with the Fig. 5 and Fig. As can be seen in Figure 6, the adjustment path of the respective rail slider 9 can be set by means of the screw elements 20, so that the window pane 10, or rather its upper edge and in particular its B-pillar-side edge, is inclined inwards in the direction of arrow a when moving into the closed position and, upon reaching the sealing element 15 of the upper frame rail 3a, is forced into a constrained position – due to the pressure of the sealing element 15 – in the direction of arrow b towards the outside of the vehicle. In other words, the window pane 10 is pre-tensioned to ensure secure closure. The position of the sealing lips 15a of the sealing element 15 when the window pane 10 reaches its target position with the desired flush-glazing appearance is shown in the figures. Fig. 5 and Fig. 6 indicated by a dash line.

[0037] In Fig.As can be seen in Figure 5, the B-pillar-side frame rail 3b has an L-shaped cross-section, so that no rail leg is present on the outside of the window pane 10 and the window pane 10 is flush with the decorative trim 3d on the outside in the desired flush-glazing appearance. By means of the two stop elements 18 for the two rail sliders 9, a constant, intended gap between the edge of the window pane 10 and the decorative trim 3d in the area of ​​the B-pillar-side frame rail 3b is maintained over time and after numerous adjustment cycles of the window pane 10 into the closed position.

[0038] In summary, the invention relates to a frame door 1 of a motor vehicle, comprising a door body 2 with a guide frame 3 and a door module 4 with two parallel guide rails 7, on each of which a rail slider 9 coupled to a window pane 10 is guided, wherein the guide rails 7 have a rail projection 7a with a stop element 18, against which the rail sliders 9 are guided in the closed position of the window pane 10.

[0039] The invention is not limited to the embodiments described above. Rather, other variants of the invention can also be derived by a person skilled in the art without departing from the subject matter of the invention. In particular, all individual features described in connection with the embodiment can also be combined with one another in other ways without departing from the subject matter of the invention.
