Description

The proposed solution relates to both an adjustment for the adjustment of a vehicle door and a vehicle with at least one vehicle door.

From the prior art, for example the DE 10 2015 012 144 A1 , adjustment devices for adjusting a vehicle door on a vehicle are known, via which a vehicle door from a closed position, in which the vehicle door closes a door opening bounded in particular by a door opening bounded on the vehicle body, with respect to a vehicle vertical axis, can be adjusted to an open position, in which the vehicle door is pivoted at least partially over the upper body-side door frame of the vehicle to release the door opening. Adjustments of vehicle doors on a vehicle can thus be realized by means of adjusting devices of this kind, which, unlike conventional swivel or sliding doors, position an open vehicle door above the door opening and, for example, in at least partial overlap in a vehicle vertical direction with the vehicle.

A similar concept is used in so-called wing doors, as it is known for sports cars, application. The goal here is to release the door opening as generously as possible. However, gullwing doors require a comparatively high space requirement for this purpose. The DE 10 2015 012 144 A1 proposes in this context, first to adjust a vehicle door via an adjusting device between a closed position in a first intermediate position by a substantially translational adjustment in a vehicle transverse direction, before the vehicle door from the first intermediate position to a second intermediate position by a substantially translational movement in the Vehicle vertical direction is adjusted. Subsequently, the vehicle door is moved by a pivoting movement into an open position, so that the vehicle door is in the open position in at least partial coverage in the vehicle vertical direction with the vehicle and thus present above a roof of the vehicle.

The from the DE 10 2015 012 144 A1 However, known adjusting device only allows the arrangement of the vehicle door in an open position on the roof and thus is particularly disadvantageous under certain circumstances, if the vehicle is parked in a garage or underground parking with low ceiling height. Another fundamental problem with vehicle doors that are pivoted upward in an open position, such as gullwing doors, and / or pivoted at least partially over the upper body side door frame of the vehicle, in the case of a vehicle rollover due to the lack of opportunity to open the vehicle door. The vehicle lying on the roof can then be left by a vehicle occupant only through a window opening or otherwise provided escape device.

Against this background, the proposed solution has the object to improve an adjustment for the adjustment of a vehicle door in this regard and to provide a vehicle improved in this respect.

This object is achieved both with an adjusting device according to claim 1 and with a vehicle according to claim 14.

A proposed adjusting device is set up and provided for the adjustment of a vehicle door on a vehicle, and allows the implementation of an adjustment of the vehicle door, wherein the vehicle door from a closed position in which the vehicle door in particular from a (relative to a vehicle vertical axis) upper body-side Door frame of the vehicle verandete door opening closes, is adjustable in an open position in which the vehicle door is at least partially pivoted over the upper body-side door frame of the vehicle away to release the door opening. About the proposed adjustment is further, when properly mounted to the vehicle, a first, body-mounted pivot axis, a second, fixed door pivot axis and a third, door-fixed pivot axis for the adjustment of the vehicle door from the closed position provided in the open position. Here, the first pivot axis and the second pivot axis are substantially parallel to each other and extend the second pivot axis and the third pivot axis substantially perpendicular to each other. A substantially parallel course of two pivot axes includes in particular a parallel course as well as a substantially vertical course of two pivot axes in particular includes each other, the two pivot axis perpendicular and thus at an angle of 90 ° to each other. Deviations of up to 10 °, in particular of up to 5 ° but should continue to be considered substantially parallel or substantially perpendicular.

Under an at least partial pivoting of the vehicle door on the upper body side door frame of the vehicle away is understood in particular that, for example, in the closed position of the vehicle door the vehicle interior facing inside of the vehicle door then in the open position above the upper body-side door frame of the Vehicle is located and is facing an upper side of the vehicle or is at least partially overlap in a vehicle device with the vehicle.

By providing a total of three different pivot axes about which the vehicle door from the closed position in the open position is pivotally, not only an adjustment of the vehicle door can be realized, via which the vehicle door can be arranged in its open position better adapted to a vehicle contour and also on respectively can be arranged above a windshield of the vehicle. Rather, a pure pivoting movement of the vehicle door about the third pivot axis can continue to be permitted via a proposed adjusting device in order to open the vehicle door.

The adjustment device provides in proposed embodiments, in particular, that the adjustment of the vehicle door is operated by external power. The adjusting device therefore has at least one motor drive, for example at least one electromotive drive for the adjustment of the vehicle door.

In one embodiment variant, the vehicle door is adjustable via the adjusting device, when the adjustment device is mounted to the vehicle, around the first pivot axis and the second pivot axis from the closed position to an intermediate position and from the intermediate position into the open position by an additional pivoting movement about the third pivot axis. A defined by the pivoting about the first and second pivot axis adjustment for the adjustment from the closed position to the intermediate position is thus superimposed from the intermediate position with a pivoting movement about the third pivot axis to then adjust the vehicle door from the intermediate position to the open position.

In this context, it can be provided, for example, that the adjustment device is configured to move the vehicle door from the closed position to the intermediate position approximately translationally along a vehicle vertical axis (in a vehicle vertical direction upward) by a pivoting movement of the vehicle door to the first, body-mounted pivot axis by a Pivoting movement of the vehicle door to the second, fixed door pivot axis is compensated. The vehicle door is thus moved by a (main) adjustment translationally-rotational about the body-mounted, first pivot axis and the door-fixed, second pivot axis over the roof. In this case, this (main) adjusting movement is superimposed from the intermediate position with a rotary adjustment movement about the further door-fixed, third pivot axis, which runs essentially perpendicular to the second door-fixed pivot axis.

By way of example, the first and second pivot axes are in each case essentially horizontally extending and the third pivot axis is guided essentially vertically, via the adjusting device, when mounted to the vehicle as intended. The above-described (main) adjustment movement into the intermediate position is thus realized by a pivoting movement about the body-mounted first horizontal pivot axis and the door-fixed horizontal second pivot axis. The adjustment movement superimposed following this (main) adjustment movement then takes place about a door-fixed vertical third pivot axis. In particular, in this embodiment, the available space on and around the vehicle is almost optimally used to adjust the vehicle door from the closed position to the open position. A complete opening, and thus unhindered entry into the vehicle, can thus be achieved even in the narrowest of situations, i. especially in tight parking spaces, small prefabricated or underground garages, be realized without the vehicle door this hinders the newcomers.

In one embodiment, the adjusting device for providing at least one of the pivot axes comprises a hinge. In particular, the adjusting device for providing the different pivot axes may comprise a lever mechanism. The adjustability of the vehicle door when mounted as intended adjustment is thus provided via a suitably designed lever mechanism of the adjustment.

In this context, for example, be provided that the lever mechanism comprises at least one pivotally mounted lever arm and a hinge. For example, the third door-side pivot axis is provided by way of the hinge via the hinge. In one possible refinement, the lever mechanism may, for example, comprise two lever arms each pivotable via a double joint and a hinge or a lever arm rotatably mounted about two axes of rotation and a hinge.

Alternatively or additionally, at least one lever arm of the adjusting device can have a variably adjustable length. Accordingly, this at least one lever arm which can be variably adjusted in length can be stepped or infinitely extensible, for example via a telescopic design of the lever arm.

In one embodiment, the adjusting device comprises an electronic control unit, which with a motor drive for the adjustment of a window pane of the vehicle door coupled or, when properly mounted to the vehicle door, coupled with such a motor drive. The control electronics can be configured, for example, to control the motor drive for lowering the window pane when the vehicle door is moved in the direction of the open position. The window of the vehicle door is thus lowered automatically and thus retracted into a body of the vehicle door when, for example, the vehicle door is moved from the closed position or from the intermediate position (further) in the direction of the open position. This also includes an automatic lowering of the window pane, when the vehicle door is moved within a range between the closed position and the open position, between the closed position and the intermediate position or between the intermediate position and the open position (further) in the direction of the open position. The control electronics in this context, for example, configured such that the window pane is maximally retracted into a body of the vehicle door when the vehicle door reaches the open position in which the vehicle door is pivoted at least partially over the upper body-side door frame of the vehicle. The window is thus regardless of when the lowering of the window is triggered, retracted maximally in the open position of the vehicle door.

Retracting or lowering the window pane offers just in a frameless vehicle door, ie, in a vehicle door without a window frame surrounding window frame the ability to reduce the height of the vehicle door so that it takes up much less space in its open position than in its closed position with Closing a window opening extended or raised window pane. An adjustment of the vehicle door in the open position, in particular a power-operated adjustment of the vehicle door in the open position is thus matched with a power-operated adjustment of the window of the vehicle door and coupled, so by retracting or lowering the window into a body of the vehicle door, the dimensions of the vehicle door for Taking the open position above the vehicle are reduced. However, the proposed solution is not limited to such a configuration and in particular an adjustment device for frameless vehicle doors.

In one embodiment, the vehicle door can be adjusted from the closed position about the third pivot axis into a pivoting position via the adjusting device, when mounted to the vehicle as intended, in which the vehicle door also releases the door opening. The adjusting device thus provides at least two different adjustment modes to open a vehicle door. On the one hand, the vehicle door can be pivoted from the closed position about the first, second and third pivot axis into the open position in a first adjustment mode via the adjusting device, in which the vehicle door is then at least partially pivoted over the upper body-side door frame of the vehicle and, for example, in at least Partial coverage in the vehicle vertical direction with the vehicle is located. Furthermore, in a second adjustment mode, comparable to a "conventional" pivoting door, the vehicle door can be adjusted and opened about the third pivot axis into a pivoting position in which the vehicle door also releases the door opening. The vehicle door is thus e.g. in this embodiment by an adjusting even then by pivoting outward to open when the vehicle comes to rest on a vehicle roof after an accidental vehicle rollover.

In one possible refinement, the adjusting device comprises an electronic control unit which is configured to adjust the vehicle door from the closed position as a function of at least one adjusting signal either into the open position or into the swivel position in order to release the door opening. The adjustment signal can be, for example, an operating signal on the part of a vehicle occupant or vehicle user, by means of which the respective person indicates which type of door opening is desired. However, the adjustment signal can likewise be a sensor signal generated by at least one sensor device, in particular, for example, a capacitive, inductively or optically generated sensor signal. Such a sensor signal can be generated, for example, depending on whether there is an obstacle in an adjustment path of the vehicle door from the closed position to the open position and / or from the closed position to the swivel position in the surroundings of the vehicle. If, for example, there is an obstacle in an adjustment path, which the vehicle door would have to travel from the closed position into the open position, the control electronics only allow the vehicle door to be opened by pivoting about the third pivot axis into the pivoting position (but also only if there is no obstacle in the pivot position to be traversed adjustment path is detected). By means of such control electronics, the adjustment device can thus open the vehicle door in different ways depending on the situation in order to allow access to the vehicle interior or exit from the vehicle interior.

On the basis of the proposed solution can also also a vehicle door with a Embodiment variant of a proposed adjustment can be provided. For this purpose, the adjustment device can form a prefabricated and pretestable assembly, for example with the vehicle door to be mounted on the vehicle.

Another aspect of the proposed solution relates to a vehicle having at least one vehicle door, which can be adjusted from an open position in which the vehicle door closes a door opening bordered in particular by an upper body-side door frame of the vehicle to an open position in which the vehicle door is at least partially open pivoted overhead vehicle body side door frame to release the door opening. The vehicle door is in this case, for the adjustment of the vehicle door from the closed position to the open position, about a first, body-mounted pivot axis, a second fixed door pivot axis and a third, fixed door pivot axis of the vehicle pivotally, wherein the first pivot axis and the second pivot axis substantially parallel to each other and extend the second pivot axis and the third pivot axis substantially perpendicular to each other.

The vehicle door may in this case include, for example, an adjustable window pane and without a window frame, thus frameless.

In particular, a variant of a proposed adjusting device may be provided on the vehicle for the adjustment of the vehicle door. Above and below explained advantages and features of embodiments of a proposed adjustment thus also apply to embodiments of a proposed vehicle door and vice versa.

In particular, it can therefore be provided, for example, that the first and second pivot axes each extend essentially horizontally and the third pivot axis extend substantially vertically on the vehicle. Alternatively or additionally, an electronic control unit may be provided which is (i) coupled to a motor drive for lowering the window pane in order to retract the window pane into a body of the vehicle door when the vehicle door is moved in the direction of the open position, and / or (ii) as a function of at least one adjustment signal, which is generated for example by a capacitive, inductive and / or optical sensor device on the vehicle, the vehicle door from the closed position either in the pivoted over the upper door frame open position or, by pivoting the vehicle door exclusively to the third To adjust, for example, vertically extending pivot axis in a pivot position to open the vehicle door.

The 1A shows a vehicle in perspective view F overlooking a vehicle longitudinal side, at the front and a rear door opening O1 . O2 are provided in the body. A front door opening O1 is here on the passenger side of the vehicle F through a side vehicle door T1 locked. The vehicle door T1 is accordingly in the 1A in a closed position.

The vehicle door T1 has an adjustable window S1 on that in the 1A is shown closed and thus completely closes a window opening. The vehicle door T1 is frameless, ie, the vehicle door T1 does not form a window frame in which the closed window pane S1 is included.

An Indian 1A illustrated coordinate system with three coordinate axes oriented perpendicular to each other defines a vehicle transverse axis X , a vehicle longitudinal axis Y and a vehicle vertical axis Z , Along the vehicle's vertical axis Z are the door openings O1 and O2 through an upper body-side door frame R bounded. This door frame R is in the front of the vehicle F eg by the A Pillar of the vehicle F educated. Between the A-pillars of the vehicle F is a front or windshield W of the vehicle F arranged. In the further course along the vehicle longitudinal axis Y is the upper door frame R through the body-side edge of a roof D of the vehicle F formed into which the A-pillar passes.

As based on the 1B and 1C for different phases of an adjustment of the vehicle door T1 is illustrated in an open position, is in the 1A to 1C illustrated embodiments, the vehicle door T1 on the vehicle F in an open position according to the 1C adjustable in the vehicle door T1 over the upper body side frame R panned away and above the windshield W is arranged. The above the body-side upper door frame R swung vehicle door T1 is in the open position with a in the closed position the vehicle interior facing the inside of the windshield W and partly the top of the roof D across from. In the open position is the vehicle door T1 thus in coverage along the vehicle's vertical axis Z with the windshield W of the vehicle F and thus runs the contour of the windshield W following inclined.

Accordingly, the calls with the 1A . 1B and 1C shown in different phases adjusting movement of the vehicle door T1 from the closed position into the open position a pivoting movement of the vehicle door T1 around a door-fixed (third) pivot axis c (see. 2 and 3 ), to a corresponding tilting of the vehicle door T1 and allow their inclination, so that the vehicle door T1 at the end of the contour of the windshield W following can be positioned. This (third) pivot axis c , which is provided door-tight, thereby runs in the closed position of the vehicle door T1 along the vertical and thus parallel to the vehicle's vertical axis Z.

In the illustrated embodiment, the required pivotal movement superimposed on this in the closed position vertical third pivot axis c a (main) adjusting movement by two further provided and each horizontally, ie, substantially parallel to the vehicle longitudinal axis Y running, swivel axes a and b ,

The 2 and 3 show an embodiment of an adjusting device designed for this purpose V , The adjusting device V includes a lever mechanism with two via one (double) joint 10 . 20 articulated connected and articulated lever arms 1 and 2 , The lever arms 1 and 2 the adjusting device V allow in combination with a door-side hinge, the one via pivot bearings 21 and 22 at the vehicle door T1 pivotally mounted lever arm 2 is formed, an adjustment of the vehicle door T1 , Starting from the closed position, about two parallel and substantially horizontally extending first and second pivot axes a and b and a pivoting movement about a third pivot axis c which are vertical and thus perpendicular to the first and second pivot axis a and b runs.

The one (first) lever arm 1 is about a first (double) joint 10 a first lever end on the vehicle body, for example in the region of the A pillar of the vehicle F , hinged so that the lever arm 1 and thus with the other end of the lever arm lever 1 connected vehicle door T1 around the first, horizontally extending and body-mounted pivot axis a is pivotable.

About the further (double) joint 20 is the one (first) lever arm 1 , in the illustrated embodiment, approximately centrally, with the other (second) lever arm 2 articulated. The other (second) lever arm 2 is about the pivot bearings 21 and 22 at its two lever ends at the vehicle door T1 , in this case on a lateral frame part of the door body of the vehicle door T1 , hinged. This is the over the joint 20 defined second pivot axis b door-mounted and allows a pivoting movement of the vehicle door T1 around the second pivot axis b relative to the first lever arm 1 ,

In one in the 2 and 3 illustrated intermediate position of the vehicle door T1 form the two hinged together lever arms 1 and 2 a T-shape. The first lever arm 1 thus extends perpendicular to the second lever arm 2 and is approximately centered with the second lever arm 2 articulated. Here it is in deviation from the representation of 2 and 3 but of course not necessarily that the two lever arms 1 and 2 in the intermediate position of the vehicle door T1 an angle of φ = 90 ° to each other.

In particular, by pivoting the first lever arm 1 around the body-first pivot axis a a stronger outward swinging the vehicle door T1 to allow, is the angle φ (that between an upper portion of the lever arm 2 and the lever arm 1 is taken) in the closed position of the vehicle door T1 significantly smaller than 90 °. The closed position is in the 2 by way of example with reference to the dashed line position of the lever arms 1 and 2 seen. Thus, in the closed position, the lever arm 1 inclined with respect to the vertical. The lever arm 2 is in contrast parallel to the vertical.

In principle, it is also possible that the lever arms 1 and 2 in the closed position of the vehicle door T1 substantially perpendicular to each other and thus φ = 90 ° applies. In particular, this relationship can - dependence on the construction of the door opening O1 - A telescopically extendable lever arm 1 Use, otherwise there may not be sufficient lift over the A-pillar and the frame R is feasible.

For a first (main) adjustment movement of the vehicle door T1 from the closed position into an intermediate position, in the embodiment shown, a translatory-rotary adjustment movement takes place about the body-mounted, horizontal first pivot axis a and the door-mounted, horizontal second pivot axis b until the vehicle door T1 with its body at least partially over the upper door frame R protrudes. During this first (main) adjustment movement into an intermediate position, a pivoting movement about the first horizontal pivot axis is achieved in order to achieve the approximately translatory adjustment movement a by pivoting the vehicle door T1 around the door-fixed second horizontal pivot axis b balanced.

In a subsequent adjustment of the vehicle door T1 from the intermediate position in the in the 1C shown open position there is a stronger rotation of the vehicle door T1 around the door-fixed second pivot axis b , After the translational adjustment of the vehicle door T, in which a pivoting movement about the first pivot axis a with a compensating pivoting movement of the same speed about the second pivot axis b is combined, the speed of the pivoting movement about the second pivot axis b elevated. The vehicle door T1 thus rotates in a first phase of an adjustment from the intermediate position to the open position about the second pivot axis b faster than the first pivot axis a , This happens until an inside of the vehicle door T1 a predefined, in particular minimum safety distance to the frame R Has. From this point on, in a second phase of the adjustment, the movement about the first pivot axis a and second pivot axis b with a rotation about the third pivot axis c superimposed to the open position. Accordingly, in a second phase of the adjustment from the intermediate position to the open position, a pivotal movement about the (in the closed position vertical) third pivot axis c superimposed perpendicular to the first pivot axis a and to the second pivot axis b runs.

1. 1. Geschlossenstellung der Fahrzeugtür T1 liegt vor (vgl. 1A);
2. 2. Translatorische Verstellung in die Zwischenstellung, bei der eine Schwenkbewegung um die erste Schwenkachse a und eine Schwenkbewegung um die zweite Schwenkachse b mit identischer Geschwindigkeit, jedoch entgegengesetzt zueinander vorgesehen sind und keine Schwenkbewegung um die dritte Schwenkachse c vorgesehen ist;
3. 3. Erste Phase der Verstellung aus der Zwischenstellung in die Offenstellung, in der die Fahrzeugtür T1 aus der Vertikalen in Richtung der Horizontalen gedreht wird, indem die Schwenkbewegung um die zweiten Schwenkachse b mit größerer Geschwindigkeit erfolgt als die Schwenkbewegung um die erste Schwenkachse a, ohne die Drehrichtungen zu ändern oder eine Schwenkbewegung um die dritte Schwenkachse c vorzusehen (vgl. 1B);
4. 4. Zweite Phase der Verstellung aus der Zwischenstellung in die Offenstellung, in der die Fahrzeugtür T1 der Neigung der A- oder C-Säule des Fahrzeugs F angepasst wird, indem die Schwenkbewegungen um die erste Schwenkachse a und zweite Schwenkachse b unverändert fortgeführt und diese mit einer zusätzlichen Schwenkbewegung um die dritte Schwenkachse c überlagert werden;
5. 5. Offenstellung der Fahrzeugtür T1 ist erreicht (vgl. 1C).

A possible expiration of the adjustment of the vehicle door T1 from its closed position into its open position can then be subdivided as follows, for example:

1. 1. Closed position of the vehicle door T1 exists (cf. 1A) ;
2. 2. Translational adjustment in the intermediate position, in which a pivoting movement about the first pivot axis a and a pivoting movement about the second pivot axis b are provided at the same speed, but opposite to each other and no pivoting movement about the third pivot axis c is provided;
3. 3. First phase of the adjustment from the intermediate position to the open position, in which the vehicle door T1 is rotated from the vertical in the direction of the horizontal by the pivoting movement about the second pivot axis b at a faster rate than the pivotal movement about the first pivot axis a without changing the directions of rotation or a pivoting movement about the third pivot axis c to be provided (cf. 1B) ;
4. 4. Second phase of adjustment from the intermediate position to the open position, in which the vehicle door T1 the inclination of the A- or C Pillar of the vehicle F is adjusted by the pivoting movements about the first pivot axis a and second pivot axis b continued unchanged and this with an additional pivoting movement about the third pivot axis c be superimposed;
5. 5. Open position of the vehicle door T1 is reached (cf. 1C ).

The planned third, door-fixed pivot axis c not only allows you to move the vehicle door T1 over the roof D of the vehicle F , Rather, this also makes it possible that the vehicle door T1 for taking their open position in addition can be tilted, so that the vehicle door T1 above the vehicle F does not have to be substantially horizontally oriented, but may be inclined. Furthermore, the third pivot axis running vertically in the closed position makes it possible c an opening of the vehicle door T1 comparable to a classic hinged door. Around the door opening O1 can thus release the vehicle door T1 over the adjusting device V on the one hand by pivoting about all three pivot axes a . b , and c in the open position of 1C on the other hand, but only by pivoting about the pivot axis c be pivoted outwards in a pivoting position.

As in particular in the embodiment of the 1A to 1C is shown is present in an adjustment of the vehicle door T1 from the closed position into the open position additionally automates the window pane S1 in a carcass body T1 retracted and lowered. The height of the frameless vehicle door T1 is thus considerably reduced in the open position. An electronic control system SE the adjusting device V can do this with a drive A a window lifter coupled to a power-operated adjustment of the vehicle door T1 automatically the windowpane S1 lower when the vehicle door T1 is adjusted in the direction of the open position, and vice versa the window S1 automatically raise again when the vehicle door T1 is moved back from the open position to the closed position.

The control electronics SE the adjusting device V can according to the presentation of the 2 Alternatively or additionally be coupled to a sensor device of the vehicle, of which the control electronics SE an adjustment signal VS can receive. This adjustment signal VS For example, it may be an operation signal to indicate whether a vehicle occupant or a vehicle user is opening the vehicle door T1 by pivoting about the vertically extending third pivot axis c or opening the vehicle door T1 by pivoting about the three pivot axis a . b and c in the open position, in the vehicle door T1 on the windshield W waving, wishes.

About the at least one adjustment signal VS (possibly in combination with other adjustment signals VS ), can also be used for the control electronics SE be signalized that in the adjustment of the vehicle door T1 - For reaching the pivot position by pivoting about the third pivot axis c or for reaching the open position by pivoting about all three pivot axis a . b and c has to be bridged - there is an obstacle. If an obstacle is detected, an appropriately triggered adjustment movement is stopped, reversed or blocked from the outset. Optionally, in dependence on a detected obstacle (indicated by at least one adjustment signal VS ) only one adjustment mode of two possible adjustment modes for the adjustment of the vehicle door T1 through the control electronics SE admitted to the vehicle door T1 either on the windshield W to fold or swing outwards analogous to a classic swing door.

The in response to an adjustment signal VS controllable adjustment movement of the vehicle door T1 is otherwise in accordance with the representation of 2 also independent of the use of a frameless vehicle door T1 even with a vehicle door T1 with a window frame FR for a windowpane S1 advantageous.

The 4A . 4B and 4C illustrate the above-explained adjustment for two on one side of a vehicle F provided vehicle doors T1 and T2 , Both, front and rear vehicle doors T1 and T2 each have an adjustable window S1 and S2 on and are as frameless vehicle doors T1 and T2 designed. Around interlocking door openings O1 and O2 of the vehicle F are both vehicle doors T1 and T2 simultaneously, but also independently adjustable from a closed position to an open position in which each of the vehicle doors T1 and T2 over the upper body-side door frame R of the vehicle F is pivoted away. While the front vehicle door T1 in its open position while above the windshield W is present, lies the rear vehicle door T2 in its open position with retracted window S2 especially the roof D and optionally a rear window of the vehicle F across from.

As the 5A and 5B can illustrate both vehicle doors T1 and T2 but also according to classical swing doors about a respective vertically extending pivot axis c or c ' be opened. The pivot axes c and c ' are in the field of A- and C Pillars of the vehicle F intended. The additional pivoting about the vertical, türfester pivot axis c or c ' thus offers not only the possibility here, one of the outer contour of the vehicle F and in particular the contour of the sloping windshield W and the roof D of the vehicle F adapted open position with the vehicle door T1 or T2 take. Rather, this is also a possibility provided, the respective vehicle door T1 or T2 even then to be able to open when the vehicle F Accidentally due to a vehicle rollover on the roof D to come to rest.
