Description

[0001] The invention relates to a system for opening a door opening of a vehicle and a method for opening a door opening of a vehicle.

[0002] Publication DE 20 2017 000 578 U1 shows a side door of a motor vehicle with a window pane.

[0003] A side door of a motor vehicle with an adjustable window is known from the publication DE 10 2017 002 256 A1.

[0004] Against this background, the task was to open a vehicle door in a suitable manner.

[0005] This problem is solved by a system and a method with the features of the independent claims. Embodiments of the system and the method are described in the dependent claims and the description.

[0006] The system according to the invention is designed at least for opening and usually also for closing the opening of a vehicle door, e.g., of a motor vehicle. The door comprises a leaf with a receptacle or recess for a pane that is movable relative to the leaf, wherein the recess is enclosed and / or surrounded by the outer walls of the leaf. The opening is arranged above the leaf or a sill and thus at the upper edge of the door leaf.

[0007] The system comprises the following components: a pane, a drive mechanism, and at least one assembly (i.e., either a single assembly or multiple assemblies). This at least one assembly, which is connected to the drive mechanism via the pane, has at least one pivot bearing. The opening of the door or window is bounded and / or enclosed at the top by a frame with a seal attached to it and at the bottom by the sash of the door or window.

[0008] The pane has an upper edge and a lower edge with a recess. In the closed position, the recess is usually completely within the sash's receptacle. Furthermore, the upper edge of the pane is in contact with the seal on the frame, being at least partially and / or watertight enclosed by the seal, for example, by at least one sealing lip. In the closed position, the pane is designed to completely close the door opening. The drive mechanism is designed to open the window from the closed position, first...first move downwards and interrupt and / or separate the contact between the upper edge of the disc and the seal on the frame.

[0009] It is possible that the frame with the seal is part of the door. Alternatively, the door may be frameless, comprising only the sash and the window. In this case, the frame with the attached seal is part of the vehicle body. Here, the frame may be part of the sash, with the opening enclosed at the bottom by the sill and at the top and sides by the frame attached to the sill, to which the seal is attached. Alternatively, in the case of a frameless door, the frame with the attached seal may be part of the vehicle body or convertible top. In this case, the opening is enclosed at the bottom by the sill and at the top and sides by the frame attached to the body or convertible top, to which the seal is attached.The system is suitable for a vehicle with a closed body or for a vehicle designed or designated as a convertible.

[0010] The at least one pivot bearing, or usually several pivot bearings, is designed to rotate or pivot the pane around at least one pivot axis, and to pivot at least the upper edge of the pane, which is lowered from the closed end position by sliding it downwards, out of the window opening. The drive is designed to reverse an initial downward movement, e.g., a sliding movement, of the pane into an upward movement, subsequently pushing the pane upwards again and pushing the recess into the opening above the sash, while continuing to push the upper edge of the pane upwards beyond the frame. In this process, the recess at the lower edge of the pane is positioned in the window opening, and the opening is at least partially opened by the released recess within the pane.

[0011] The system is designed to include at least one arrangement comprising an upper pivot bearing, two lower pivot bearings, and an adjusting lever. The upper pivot bearing is configured to rotatably connect an upper pivot point of the disc to the sash, for example, an outer wall thereof. Alternatively or additionally, the adjusting lever has an elongated hole and a circular hole, wherein the adjusting lever is movably connected to the disc via the elongated hole and a lower pivot bearing on the disc side, and wherein the adjusting lever is movably connected to the door via the circular hole and a lower pivot bearing on the door side. Alternatively or additionally, the adjusting lever and the two lower pivot bearings are configured to movably connect a lower pivot point of the disc on the disc side to the sash.

[0012] In a further embodiment, the at least one arrangement comprises an adjusting bolt and two cam elements, wherein the adjusting bolt is connected to the disc. The cam elements are arranged on a surface of the adjusting lever, usually attached to it. The cam elements are designed to mutually influence the movement of the adjusting bolt and the movement of the adjusting lever when the adjusting bolt, during its movement, comes into contact with at least one cam element, and it is possible that the drive is switched as a trigger due to such contact.

[0013] In a further embodiment, at least one arrangement has a sliding element, wherein the sliding element is rotatably or pivotably connected to the adjusting bolt via a swivel arm. Furthermore, the sliding element is connected to the drive via a drive element, e.g., a cable.

[0014] Furthermore, at least one arrangement includes a lifting module that is mounted on a support profile of the wing and is designed to lift the adjusting bolt. For this purpose, a sleeve is provided on and / or attached to the adjusting bolt, typically having a rim or collar at the top. The sleeve surrounds the adjusting bolt coaxially to its longitudinal axis. The pivot arm is located at one end of the adjusting bolt. The adjusting bolt is displaceable relative to the sleeve within a hole enclosed by the sleeve. The sleeve is displaceable between a lowering position and a lifting position parallel to the longitudinal axis of the adjusting bolt. To lift the adjusting bolt, the sleeve is pushed or moved from the lowering position to the lifting position by at least one of the cam elements, thereby pressing against the bolt.Its edge rests against the swivel arm, which serves as a stop for the sleeve. The adjusting bolt is thereby moved by at least one cam element over the sleeve from the lowering position to the raising position, and thus also raised.

[0015] The system comprises two arrangements, each typically containing the same components mentioned above. These two arrangements are located on opposite outer lateral edges of the disk, with a first arrangement typically located on a left edge and a second arrangement typically located on a right edge. It is possible that at least one component of the at least one arrangement, e.g., the upper pivot bearing, the lower disk-side pivot bearing, the sliding element, and / or the adjusting bolt, is indirectly connected to the disk via the sleeve as a disk connector and / or a guide rail.

[0016] The method according to the invention is designed for opening and, optionally, also closing the opening of a vehicle door using a system, for example, an embodiment of the system described above, wherein at least one step of the method is performed with at least one component of the system. The door has a wing with a receptacle, the opening being arranged above the door wing. The system has an electrical and / or mechanical drive and at least one assembly comprising at least one pivot bearing. Furthermore, the opening is bounded and / or enclosed by a frame with a seal and the door wing. The pane has an upper edge and a lower edge with a recess or indentation. The recess, as a hole at the lower edge of the pane, is located in the receptacle of the wing in the closed end position of the pane and is enclosed by the wing.Furthermore, the upper edge of the pane is in contact with the seal on the frame, with the upper edge being positioned on or within the seal and possibly partially enclosed by it. The opening of the window above the sash is completely sealed by the pane in the closed position.

[0017] To open the window, the drive unit first moves the pane downwards from its closed position, interrupting and / or separating the contact between the upper edge of the pane and the seal on the frame, thus opening a slot between the seal and the upper edge. The pane is then rotated around a pivot axis by or via the at least one pivot bearing, and at least the upper edge of the pane is pivoted out of the window opening. The drive unit then pushes the pane upwards again, pushing the recess into the opening above the sash. Furthermore, the upper edge of the pane is pushed upwards beyond the frame.

[0018] The method is performed for a disc that is connected to the sash via two pivot bearings and an adjusting lever, with at least one cam element arranged on the adjusting lever. Furthermore, an adjusting bolt connected to the disc is moved either upwards or downwards along a displacement axis. The direction of movement of the adjusting bolt, which, for example, starting from the closed end position of the disc, is initially oriented from top to bottom, is reversed from bottom to top when the adjusting bolt, during its downward movement, comes into contact with the at least one cam element, for example, by striking and touching it. The pivot bearing between the lower disc-side and door-side pivot bearings is also moved.movable adjusting levers are rotated, whereby it is possible that the drive is switched by the adjusting lever as a switch for the drive when at least one cam element is touched by the adjusting bolt and continues to be actuated.

[0019] The method and system make it possible to open a window opening with a pane designed or described as a freeform pane. If the presented system has two described arrangements, these can be assigned to opposite lateral edges of the pane and, in a specific configuration, arranged symmetrically to each other, regardless of any asymmetrical shape of the pane. In this configuration, identically designed components of the two arrangements can move synchronously in one implementation of the method.

[0020] In this process, the pane follows a circular path only below the sill or the upper edge of the sash. To open the window, the pane is briefly lowered until it reaches its lowest position, at which point its upper edge is pulled downwards out of the vehicle-mounted seal on the frame by the window regulator. From this lowest position, the regulator then moves the pane upwards, raising its recess or pulling it out of the sash. Its upper edge is positioned above the door frame, and a smaller opening is formed above the sill by the recess or cutout at the bottom edge of the pane. Because the pane pivots around the axis of the upper pivot bearing, the recess is moved upwards at an angle towards a seal on the sash's sill. When the door is subsequently closed, the recess retracts back into the sash.The two guide rails, usually arranged on both sides, for guiding the disc form a pivoting guide frame, which is usually located below the parapet.

[0021] Typically, on a front door of a vehicle, such as the driver's or passenger's door, the door frame is also formed and / or limited by the vehicle's A-pillar and B-pillar. If one of the pillars runs perpendicular to the door sill, the guide rail associated with that pillar may be pivotable. In this process, the window and the two guide rails pivot, with the adjustment lever also serving as the pivoting lever. The window is usually guided during movement by the existing window regulator drive, but it can also be moved separately by a drive independent of the window regulator. The window regulator typically uses a double-strand cable, divided into several sections, to move the window. This process ensures compliance with legally prescribed minimum radii for the protruding edge of the window, if applicable.via a window-mounted additional frame, taken into account and adhered to.

[0022] The system offers the possibility of new designs for the door and / or its sash. A space is created within the sash or lower section of the door for stiffening measures and pockets. In the fully open position of the sash, the recess above the sill creates a slot that can be used, for example, in a parking garage, at a border crossing, or at a police checkpoint, as a pass-through for a document such as a parking ticket or identification card.

[0023] In the closed position, the upper edge of the pane rests against the frame's seal to acoustically insulate the vehicle's interior from the surrounding environment and the resulting wind, even at higher speeds. For this purpose, the upper edge of the pane is enclosed by the seal, ensuring it is held in place and cannot lift off.

[0024] In this embodiment of the method, the door is opened from its closed end position, and the pane is moved to the open end position. The door is then closed again, with the pane moving from the open end position back to the closed end position. During this movement, the pane is moved relative to the door frame along a path resembling a heart-shaped curve. When the direction of movement reverses at the pane's lowest position, a decision is made as to whether the pane, after reversing the direction of movement, will move either to the closed end position, with its upper edge positioned in and / or against the seal, or to the open end position.

[0025] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0026] The invention is schematically illustrated with reference to embodiments in the drawing and is described schematically and in detail with reference to the drawing.

[0028] The embodiment of the system according to the invention is provided for a door, here a side door, on the left or right side of a vehicle, which is here designed as a motor vehicle. The door has a sash 2 or door leaf and a pane 4 for a window in the door. The opening of this window is bounded at the top and on each side by a frame 8 with a seal arranged thereon, and at the bottom by an upper straight edge of the sash 2, the upper edge of which is also referred to as the sill. This frame 8 can be part of the door or part of the vehicle body, with a frame designed as part of the body closing the door opening when the sash 2 of the door is in a closed position. The pane 4 has an upper curved edge, two straight lateral edges, and a lower edge with a recess 6, the lower edge enclosing the recess 6 on one side.Furthermore, the disk 4 has a left lower end and a right lower end, with these two ends defining a curved section of the lower edge of the disk 4 on the left and right.

Terms such as "above" or "above", "below" or "below", "left" and "right", which here describe spatial relationships of the elements in the Fig. 1a, Fig. 1b, Fig. 1c, Fig. 2a, Fig. 2b, Fig. 2c, Fig. 2d, Fig. 2e, Fig. 2f, Fig. 2g, Fig. 2h, Fig. 2i, Fig. 2 years Fig. 2k, Fig. The components or parts shown in section 2l are described here as referring to an installation position of the door in a side wall of a vehicle body and thus also to a gravitational field of the earth. Fig. Figure 1c shows, among other things, a left edge of the pane 4 and components associated with that left edge. Furthermore, the term "door-side" means that a component faces and / or is associated with an outer wall 30 of the sash 2. The term "pane-side" means that a component faces and / or is associated with the pane 4 or the guide rail 10 for the pane 4. In an alternative embodiment, it is conceivable that at least the terms "door-side" and "pane-side," as well as "left" and "right," are reversed from the schematic representations shown here, for example, for an opposing door or side door on a different, i.e., right or left, side of the vehicle, and could alternatively be shown in reverse, without functionally affecting the embodiment of the system according to the invention and the embodiment of the method according to the invention that can be implemented with it.Each edge of disk 4 can also be designed or referred to as an edge.

[0032] The embodiment of the system according to the invention for moving this disc 4 has a guide rail 10 on the left and right sides. A straight lateral edge of the disc 4 is arranged in a groove of each guide rail 10. Furthermore, the door and the system comprise a window regulator with two support modules 12, which are designed here as strips and are arranged between the guide rails 10 and the lateral edges of the disc 4, respectively. A deflection pulley 18 is arranged at each upper and lower end of a support module 12, and a closed cable 16 of the window regulator is wound around the four deflection pulleys 18, whose deflection axes are arranged at the corners of a parallelogram.The cable 16 runs successively around the lower pulley 18 of the left support module 12, around the upper pulley 18 of the left support module 12, around the lower pulley 18 of the right support module 12, around the upper pulley 18 of the right support module 12, and from there again around the lower pulley 18 of the left support module 12. A section of the cable 16 between the upper left pulley 18 and the lower right pulley 18 crosses another section of the cable 16 between the upper right pulley 18 and the lower left pulley 18. The window regulator also includes an electric and / or mechanical drive 14 with which the cable 16 is moved.

[0033] In the embodiment of the method according to the invention, the disc 4 is moved via the window regulator, which has the support modules 12 with the deflection pulleys 18, the drive 14 and the cable 16 as components, starting from a first pivot position S1 ( Fig. 2a, Fig. 2b), if they are still in the closed end position E1 ( Fig. 1a) is located in a second pivot position S2 ( Fig. 2a, Fig. 2b) pivoted and largely vertically from bottom to top into the open end position E2 ( Fig. 1b) displaced, whereby it can then also be displaced downwards in the opposite direction into the closed end position E1. In doing so, the disc 4 and the guide rail 10 are moved about an upper pivot axis 26 of a Fig. The upper pivot bearing 35 shown in Figure 2a pivots between the two pivot positions S1 and S2, with the upper pivot axis 26 running parallel to the usual forward direction of travel of the vehicle above the support modules 12 and below the parapet or an upper edge of the wing 2. Furthermore, the disc 4 is also moved vertically between the two end positions E1 and E2. At least one component of this window regulator can also be designed as a component of the embodiment of the system according to the invention.

[0034] The embodiment of the system according to the invention has an arrangement for both the right and left edges of the disc 4, comprising a sliding element 20, an adjusting bolt 22, an adjusting lever 24, and three pivot bearings 32, 34, 35. Here, a left-hand adjusting bolt 22 is attached to a left section of the cable 16 between the upper and lower deflection pulleys, and a right-hand adjusting bolt 22 is attached to a right section of the cable 16 between the upper and lower deflection pulleys 18 of the right support module 12. Each adjusting bolt 22 is pivotably connected to a respective sliding element 20 via a pivot arm 40. Fig. 2c). Furthermore, a left sliding element 20 is attached to or connected with the left lower end of the disc 4 and a right sliding element 20 is attached to or connected with the right lower end of the disc 4. Accordingly, each lower end of the disc 4 is indirectly connected to a respective section of the cable 16 via a respective sliding element 20, a respective swivel arm 40 and a respective adjusting bolt 22.

[0035] Details on this can be found in the Fig. 2a, Fig. 2b, Fig. 2c, Fig. 2d, Fig. 2e, Fig. 2f, Fig. 2g, Fig. 2h, Fig. 2i, Fig. 2 years Fig. 2k, Fig. 2l schematically represented, whereby this Fig. 2a, Fig. 2b, Fig. 2c, Fig. 2d, Fig. 2e, Fig. 2f, Fig. 2g, Fig. 2h, Fig. 2i, Fig. 2 years Fig. 2k, Fig. 2l show the details from a perspective that is in Fig. 1c is indicated by an arrow 28, which is oriented parallel to the forward direction of travel of the vehicle. The disc 4 is in the Fig. 2a and Fig. 2b shows, on the one hand, the disk 4 in the first pivot position S1 with respect to the pivot axis 26, and also in the closed end position E1, and on the other hand, in the second pivot position S2 with respect to the pivot axis 26, whereby the disk 4 also reaches the open end position E2 from this point if it is pushed further upwards. The disk 4 is in Fig. 2d only in the first pivot position S1 and in the closed end position E1, and in the Fig. 2e and Fig. 2f is shown schematically in an additional tilted pivot position S3 between the two other pivot positions S1, S2. Furthermore, it shows Fig. 2a components, in a first level ( Fig. 2a), which runs through the adjusting lever 24 and the guide rail 10.

[0036] In this case, on an inner side of the metallic outer wall 30 of the wing 2, which here is designed as a door panel, there is a feature only in Fig. 2a upper plant profile 33 shown and one in the Fig. 2b, Fig. 2d, Fig. 2e, Fig. 2f, Fig. 2g, Fig. 2i, Fig. 2 years Fig. 2k, Fig. The lower mounting profile 31 shown in Figure 2l is arranged, wherein the mounting profiles 31, 33 are designed and / or designated here as mounting plates. An upper pivot point of the disk 4, and thus also of the guide rail 10, is connected via the upper pivot bearing 35 to the upper mounting profile 31, and thus to the wing 2, by means of an additional bolt that passes through a pivot axis 26 of the upper pivot bearing 35. Fig. 1a and Fig. The upper pivot axis 26 shown in Figure 1b is pivotably connected, wherein the guide rail 10 and the disk 4 are pivoted or rotated about the pivot axis 26 of the upper pivot bearing 35 when the procedure is carried out. Furthermore, a first lower, door-side pivot bearing 32, shown here on the right, is arranged at a pivot point of the outer wall 30 of the sash 2, and a second lower, disk-side pivot bearing 34, shown here on the left, is arranged at a lower pivot point of the disk 4 and / or the guide rail 10, and are usually attached.

[0037] The following show Fig. 2b, Fig. 2d, Fig. 2e, Fig. 2f, Fig. 2g, Fig. 2i, Fig. 2 years Fig. 2k, Fig. Two components are arranged in a second plane, which runs parallel to the first plane through the lower mounting profile 31, the sliding element 20, and the adjusting bolt 22. The second plane is positioned on the first plane with respect to the forward direction of travel indicated by arrow 28.

[0038] How Fig. As shown in Figure 2a, the adjusting lever 24 is designed as a largely triangular plate with rounded corners and slightly convex outwardly curved legs located between them. Here, a right-hand corner on the door side faces the outer wall 30. An additional bolt of the lower right-hand door-side pivot bearing 32 passes through a circular hole in the adjusting lever 24, which corresponds to the door-side corner of the adjusting lever 24. Along a left-hand, disc-side leg of the adjusting lever 24, which is opposite the door-side corner, an elongated hole 36 runs through the adjusting lever 24 between an upper and a lower disc-side corner of the lever.This elongated hole 36 comprises a straight section which, starting from the upper disc-side corner, runs largely parallel to the disc-side leg, wherein the elongated hole 36 has a bend at the lower disc-side corner in the direction of the circular hole for the right door-side pivot bearing 32.

[0039] An additional bolt of the lower disc-side pivot bearing 34 is displaceable within the elongated hole 36 between an upper end of the elongated hole 36, which faces the upper disc-side corner of the adjusting lever 24, and a lower curved end of the elongated hole 36, which faces the lower disc-side corner of the adjusting lever 24. Fig. As shown in Figure 2a, the additional bolt of the disc-side pivot bearing 34 is located in or on a lower end stop at the lower end of the elongated hole 36 when the disc 4 is in the first pivot position S1 and simultaneously in the closed end position E1. Fig. As also shown in Figure 2a, the additional bolt of the disc-side pivot bearing 34 is alternatively located at an upper end stop at an upper end of the elongated hole 36 when the disc 4 is in the open end position E2 and / or in the second pivot position S2. In this case, Fig. 2a The respective position of the disc-side pivot bearing 34 within the elongated hole 36 is shown for the two pivot positions S1 and S2. When the disc 4 transitions from the first pivot position S1 to the second pivot position S2, the additional bolt of the pivot bearing 34 is moved within the elongated hole 36 from the lower to the upper end stop, and conversely, when transitioning from the second pivot position S2 to the first pivot position S1, it is moved from the upper to the lower end stop. The adjusting lever 24 is pivoted or rotated about the right-hand door-side pivot bearing 32 clockwise upwards in the first pivot position S1 and downwards in the second pivot position S2.

[0040] Furthermore, the adjusting bolt 22 is displaceable either upwards or downwards along a lifting module 48, which is arranged on the lower support profile 31. The lifting module 48 has an end-face contour and / or can be described as such. The lifting module 48 can be designed as a lifting plate.

[0041] An upper cam element 42 is attached to the adjusting lever 24 or to a surface of the adjusting lever 24 facing the adjusting bolt 22, here at the upper glass-side corner of the adjusting lever 24. A lower cam element 44 is also attached to the surface of the adjusting lever 24 facing the sliding element 20, with this lower cam element 44 being arranged and / or extending between the lower glass-side corner and the door-side corner. The two cam elements 42, 44 are arranged between the adjusting lever 24 and the adjusting bolt 22, which is pivotably mounted on the sliding element 20.

[0042] The upper cam element 42 has a body with a pointed end and an opposite thick or thickened end, the body widening from the first end to the second end. A longitudinal axis of the upper cam element 42, or of its body, is arranged largely parallel, i.e., parallel to or at an acute angle, to a line running between an upper and a lower disc-side corner of the adjusting lever 24.

[0043] The lower cam element 44 has a rectangular, largely trapezoidal body with four corners. A first corner of the lower cam element 44 is located next to the bend of the elongated hole 36 on the adjusting lever 24, between the lower, disc-side corner and the door-side corner of the adjusting lever 24. A second corner (here clockwise) is located along the disc-side leg of the adjusting lever 24 next to the elongated hole 36, specifically at the transition between the straight section and the bend at the lower end of the elongated hole 36. A third corner of the lower cam element 44 is located next to the circular hole, and a fourth corner is located on the circular hole of the adjusting lever 24. A first outer surface of the lower cam element 44 between the first and second corners is straight.A second outer surface between the second and third corners is concave, a third outer surface between the third and fourth corners is largely straight, and a fourth outer surface between the third and fourth corners is convex. A line running parallel to the fourth outer surface and the longitudinal axis of the upper backdrop element 42 are arranged at an acute angle to each other.

[0044] Individual, here chronologically successive, steps of the implementation of the method are based on the Fig. 2a, Fig. 2b, Fig. 2d, Fig. 2e, Fig. 2f, Fig. 2g, Fig. 2i, Fig. 2 years Fig. 2k, Fig. Figure 2l schematically illustrates this. The sliding element 20 and the adjusting bolt 22, which are arranged on the left section of the cable 16, are moved axially along the displacement axis 46, which here runs parallel to the left section of the cable 16, either vertically downwards (arrow 50) or in the opposite direction upwards (arrow 52) relative to the lower support profile 31 and the door-side pivot bearing 32 or the pivoting adjusting lever 24, depending on the direction in which the cable 16 is moved by the drive 14. Similarly, the disc 4 with the guide rail 10, which is connected to the left and right sections of the cable 16 via the sliding elements 20 and adjusting bolts 22, is also moved upwards or downwards relative to the sash 2.

[0045] In the embodiment of the method with the embodiment of the system according to the invention and described above, it is provided that the disk 4 is originally in the closed end position E1 ( Fig. 1a) and the first pivot position S1, and the vehicle window is closed. The system provides a pivoting mechanism for the window 4 when the procedure is carried out. As shown in the Fig. 2b indicated the line which runs parallel to the fourth outer side of the lower cam element 44 and the longitudinal axis of the upper cam element 42 is arranged or oriented at an acute angle relative to the displacement axis 46.

[0046] In the first step of the process ( Fig. 2d) The section of cable 16 is moved downwards by the drive 14 of the window regulator, whereby the adjusting bolts 22 on the lateral sections of the cable 16 and the sliding elements 20 connected to them via the pivot arms 40 are initially pushed downwards by the drive 14 of the window regulator. In doing so, the upper edge of the pane 4 is moved downwards out of and / or detached from the seal on the frame 8, with the upper edge of the pane 4 being positioned below the seal, and a gap being established between the upper edge and the seal. In addition, the adjusting bolt 22 is also moved axially downwards (arrow 50) along the displacement axis 46 and pushed between the lifting module 48 and the upper cam element 42. Furthermore, the adjusting bolt 22 is also raised by the lifting module 48 at the mounting profile 31 for the adjusting bolt 22.

[0047] In the second step ( Fig. 2e) The pane 4 and its guide rails 10 on both sides are tilted relative to the opening in which the pane 4 was originally positioned when the window was closed, about the pivot axis 26, and arranged in the tilted pivot position S3. Due to the movement of the sliding elements 20 and thus also the adjusting bolts 22, the upper edge of the pane 4 is lowered relative to the frame 8 of the window. In addition, the left adjusting lever 24, shown explicitly, is rotated clockwise downwards about the pivot bearing 32, while the other, right adjusting lever 24 on the right side of the pane 4 is rotated counterclockwise downwards in a symmetrical system configuration. This rotation of the adjusting lever 24 aligns the longitudinal axis of the upper cam element 42 attached to it parallel to the sliding axis 46.

[0048] It is provided that the downward movement of the adjusting bolt 22 (arrow 50) is stopped by the lower cam element 44 when the adjusting bolt 22 reaches the second outer side of the lower cam element 44 and rests on and / or on it or comes into contact with it, whereby the adjusting bolt 22 reaches a minimum or lowest reversal position, and the disk 4 also reaches a lowest disk position.

[0049] As soon as the adjusting bolt 22, starting from its downward movement along the displacement axis 46, reaches its minimum reversal position, its movement is reversed by the drive 14 and the upward-moving section of the cable 16, causing it to move upwards (arrow 52). As a switching mechanism to trigger such a reversal of the direction of movement of the adjusting bolt 22 by the drive 14, the adjusting bolt 22 is used here when it strikes the second outer surface of the upper cam element 42, at which point the adjusting bolt 22 reaches its lowest reversal position.

[0050] Furthermore, the axially displaced adjusting bolt 22, which is raised by the lifting module 48, slides upwards over a contour or cam contour of the lifting module 48 ( Fig. 2f). Subsequently, the sliding element 20 and the adjusting bolt 22 are pushed further upwards by the drive 14 ( Fig. 2g). The correspondingly upward-shifted disc 4 reaches the in Fig. 1b shows the open end position E2.

[0051] Fig. Figure 2h shows the adjusting bolt 22, at the upper end of which the pivot arm 40 is arranged, via which the adjusting bolt 22 is rotatably connected to the sliding element 20. A sleeve 54 with a rim or collar at its upper end is arranged on and / or attached to the adjusting bolt 22 below the pivot arm, at least partially, and possibly completely, enclosing the adjusting bolt 22. The sleeve 54 is designed here as a disc connector and can also be configured or referred to as a cam follower. The adjusting bolt 22 is connected to the respective lower end of the disc 4 via the sleeve 54, providing a disc connection. The adjusting bolt 22 rests against the cam follower 54 and the lifting module 48, and is slidably positioned along a lifting axis 56 between the cam follower 54 and the lifting module 48, as indicated here by a double arrow 58.In this case, one longitudinal axis of the adjusting bolt 22 corresponds to the lifting axis 56 and / or runs coaxially to the lifting axis 56.

[0052] In the embodiment of the system presented here, the adjusting bolt 22, which is at least partially received in and / or at least partially enclosed by the sleeve 54, is also arranged to be displaceable along the displacement axis 46 between the lifting module 48 and the upper cam element 42. The lifting axis 56 is oriented parallel to a central axis of the adjusting bolt 22 and perpendicular to the displacement axis 46. In this process, the adjusting bolt 22 is displaced along the lifting axis 56 by or with the sleeve 54. [Figure 1 shows...] Fig. 2h the sleeve 54 in both a lowering position (bottom) and a raising position (top), as well as the adjusting bolt 22 in a raising position. To move the adjusting bolt 22 from a lowering position to the raising position, the sleeve 54, or rather the rim arranged on it, presses from below against the pivot arm 40, which has a larger diameter than the adjusting bolt 22 with respect to its longitudinal axis. The contour of the lifting module 48 is designed as a ramp. The lifting module 48, or rather its contour, is designed to guide a rim of the sleeve 54 on the adjusting bolt 22 and to move the sleeve 54 axially to the lifting axis 56 and relative to the adjusting bolt 22.

[0053] The further Fig. 2i, Fig. 2 years Fig. 2k, Fig. Figure 21 shows a reverse movement of the sliding element 20, the adjusting bolt 22 and the adjusting lever 24, with a correspondingly reversed movement of the disc 4 starting from the open end position E2 ( Fig. 1b) relative to the opening above the wing 2 of the door, until it returns to the closed end position E1 ( Fig. 1a) achieved.

[0054] The downward-moving adjusting bolt 22 strikes the upper cam element 42 on the adjusting lever 24 from above. This causes the adjusting bolt 22, which is arranged on the pivot arm 40, to pivot away from the lifting module 48 in the direction of the door-side pivot bearing 32 ( Fig. 2j). Furthermore, after moving downwards past the first cam element 42, the adjusting bolt 22 comes into contact with the lower cam element 44, pivoting back towards the lifting module 48 along the second concave outer surface of the lower cam element 44. In this process, the adjusting bolt 22 reaches its intended minimum or lowest reversal position, and the disc 4 also reaches its lowest or minimum disc position, as described in Fig. 2e is shown schematically. With a corresponding downward movement of the disc 4, the upper edge of the disc 4 is positioned below the frame 8 with the seal.

[0055] Then, starting from the minimum or lowest reversal position, the adjusting bolt 22 (arrow 52) and the disc 4 are moved upwards again from the lowest disc position by the drive 14 and thus by the window regulator (arrow 52). Fig. 2k, Fig. 2l), wherein the upper edge of the pane 4 is pushed from below against the seal and is arranged again in and / or on the seal on the frame 8, wherein the upper edge dips into the seal, and wherein the opening of the window is completely closed by the pane 4 and is usually sealed watertight when the upper edge of the pane 4 and the seal on the frame 8 are in contact, wherein the pane 4 is again in the closed end position E1.

[0056] In this embodiment of the method, the disc 4 is initially in the first pivot position S1 and in the closed end position E1. From this position, it is pivoted or rotated into the second pivot position S2 and positioned in the open end position E2. The edge of the sleeve 54 is already engaged with and / or in contact with the lifting module 48 in the first pivot position S1 of the disc 4. As the opening is opened, the adjusting bolt 22 is pushed or moved downwards (arrow 50) through the disc 4. During this movement, the sleeve 54, located on the adjusting bolt 22, is lifted from its lowered position by the front contour of the lifting module 48, with the edge or collar of the sleeve 54 sliding against and / or on the lifting module 48.As soon as the adjusting bolt 22 has reached the minimum reversal position, it is pushed upwards (arrow 52), whereby the disc 4 is also pushed upwards and arranged in the open end position E2.

[0057] Conversely, when the disc 4 is initially in the second pivot position S2, the adjusting bolt 22 is moved upwards (arrow 52) from the minimum reversal position by the disc 4 when the opening is closed, whereby both cam elements 42, 44 are passed by the adjusting bolt 22, whereby at least one of the cam elements 42, 44 is touched, pressed, acted upon and / or passed over by the sleeve 54. In such a movement of the disk 4, when it is pivoted from the second pivot position S2 back to the first pivot position S1 and from the open end position E2 is moved largely vertically downwards into the closed end position E1, the adjusting bolt 22, which is moved upwards (arrow 52), with the sleeve 54 enclosing it, follows the cam elements 42, 44, whereby an upper part of at least one cam element 42, 44 engages with the sleeve 54, e.g. the edge arranged on top of it.collar, in engagement, with the disk 4 performing a pivoting movement from the second pivot position S2 or the open end position E2 to the first pivot position S1 or the closed end position E1.
