Object of the present invention is to provide a motor vehicle with a flexible for different vehicle types door device and such a door device.

This object is achieved by a motor vehicle having the features of patent claim 1 and by a door device having the features of patent claim 10. Advantageous developments of the invention are given by the dependent claims.

• - eine Fahrzeugtür,
• - eine Führungskulisse, welche einen Führungsweg, entlang welchem die Fahrzeugtür geführt bewegbar ist, zumindest bereichsweise begrenzt, und welche an einer Karosserie des Kraftfahrzeugs angeordnet ist,
• - ein erstes Führungselement, welches einerseits bewegbar mit der Führungskulisse und andererseits mit einem ersten Türbereich der Fahrzeugtür gekoppelt ist, und
• - ein zweites Führungselement, welches einerseits drehbar mit der Karosserie des Kraftfahrzeugs und andererseits drehbar mit einem zweiten Türbereich der Fahrzeugtür gekoppelt ist.

A first aspect of the invention relates to a motor vehicle with a door device comprising

• - a vehicle door,
• a guide slot which delimits a guide path along which the vehicle door is guided, at least in regions, and which is arranged on a body of the motor vehicle,
• a first guide element, which is, on the one hand, movably coupled to the guide slot and, on the other hand, to a first door region of the vehicle door, and
• - A second guide member which is rotatably coupled on the one hand with the body of the motor vehicle and on the other hand rotatably connected to a second door portion of the vehicle door.

The guide slot may be formed, for example, as extending over a portion of the body guide groove or as a guide rail, to name just a few examples. The respective door regions may preferably be spaced from each other.

According to the invention, the first guide element has two element regions arranged at a distance from one another in the vehicle transverse direction of the motor vehicle, of which a first element region is connected in a rotationally fixed manner to the vehicle door and a second element region is movably coupled to the guide link. This is advantageous because a particularly defined guidance of the vehicle door, for example between a closed position and an open position, along the guide slot and thus along the guide path is made possible by the rotationally fixed connection between the vehicle door and the first guide element. By the first guide member, the vehicle door can be kept spaced from the guide slot and thereby guided guided along the guide slot. Characterized in that the vehicle door along the guide slot movable and also held on the first guide member spaced from the guide slot, the door device can be very flexible overall for different types of vehicles, so for example as convertibles, vans, sedans, just to name a few used , This is due to the fact that a combination of the non-rotatable connection between the first element region and the vehicle door in conjunction with the coupling of the vehicle door via the second guide element, which is rotatably coupled both to the body and to the vehicle door Sliding movement and pivoting movement when moving the vehicle door is possible.

The second element region may preferably be rotatable relative to the guide slot and coupled along the guide path displaceable with the guide slot. This can be done when moving the vehicle door in a particularly simple manner, both a rotational movement and a sliding movement.

In other words, the second element region of the first guide element can be both displaceable relative to the guide slot and rotatably coupled to the guide slot relative to the guide slot. Due to the rotationally fixed connection between the first element region and the first door region of the vehicle door, the vehicle door can be moved in a particularly defined manner along the guide slot, at least at its first door region.

The second element region can preferably be coupled directly to the guide slot. This allows a particularly defined movement of the vehicle door.

The first element region may be formed as a first element end and the second element region as a second element end of the first guide element opposite the first element end.

The first element region can in particular be rigidly connected to the vehicle door.

The first guide element can preferably be designed as a lever element, in particular as a lever arm, whereby a particularly simple coupling between the vehicle door and the guide link is made possible.

The second guide element may be formed, for example, as a pivoting hinge. The pivoting hinge may preferably be rotatably mounted on the body side and on the door side.

The first door area can be arranged in the forward direction of travel of the motor vehicle, that is, in the vehicle longitudinal direction of the motor vehicle, in front of the second door area. As a result, the first door area may, for example, be closer to a front wheel of the motor vehicle than the second door area.

In an advantageous further connection of the invention, the vehicle door is guided by means of coupled to the guide slot first guide element at least displaceable between a closed position and an open position and thereby displaceable relative to the guide slot and pivot. This is advantageous since the first guide element is thus coupled to the guide slot both in the closed position and in the open position, whereby the vehicle door can be supported in a particularly favorable manner, at least in regions, on the guide slot both in the closed position and in the open position ,

In a further advantageous further connection of the invention, the guide slot is integrated in a sill of the body. This is advantageous because a storage of the vehicle door on a vehicle pillar, for example on a B-pillar - unlike conventional door systems - can be omitted. As a result, the door device is also particularly flexible for B-pillarless vehicle types.

In a further advantageous further connection of the invention, the guide path has at least one inflection point at which a curvature behavior of the guide path changes. This is advantageous since, due to the change in the curvature behavior at the point of inflection during the movement of the vehicle door, a change in a rotary motion component and a displacement component over the guide path can be or can be given with particularly little effort. By changing the curvature behavior, in other words, the movement of the vehicle door can be specified in a particularly simple manner.

In a further advantageous further connection of the invention, the guide path has at least two differently oriented curvatures, between which the inflection point is arranged. This is advantageous, since in a particularly simple manner, for example, a progressive and / or degressive course of the guide path can be predetermined in relation to the vehicle longitudinal direction of the motor vehicle.

A first curvature of the curvatures may, for example, be progressively curved and a second curvature of the curvatures, for example, degressive, wherein the first curvature in the vehicle longitudinal direction may be arranged before the second curvature. This is advantageous since, during the movement along the first curve, a proportion of the movement of the vehicle door in the vehicle transverse direction can be greater than in the vehicle longitudinal direction, whereas in the movement along the second curve the proportion of movement in the vehicle longitudinal direction can be greater than in the vehicle transverse direction. In other words, during the movement along the first curvature, at least predominantly a displacement of the first door area in the vehicle transverse direction and during the movement along the second curvature at least predominantly a displacement of the first door area in Vehicle longitudinal direction. By such curvatures, the movement of the vehicle door can be particularly defined and easily specified.

In a further advantageous further connection of the invention, the second guide element is rotatably coupled to the vehicle door at at least two spaced-apart bearing points on the second door region. This is advantageous because a particularly stable mounting of the vehicle door by means of the second guide element on the body and a particularly defined rotational movement of the vehicle door is made possible by the two spaced bearings at least at the second door area.

Of particular advantage here is that by the fact that the second guide member is rotatably coupled to the at least two spaced bearing points on the second door area with the vehicle door and also the first guide member with the guide slot, a total of at least a 3-point storage of the vehicle door opposite the motor vehicle, so in other words a storage of the vehicle door to a total of at least three bearings can be created.

The three bearings ideally have a particularly large distance from each other, whereby the vehicle door can be stored particularly stable on the motor vehicle.

In a further advantageous further connection of the invention, the vehicle door is at least partially formed as Radlaufsegment the body. This is advantageous because the vehicle door thus has a particularly high functionality, especially since the wheel arch segment can accordingly take on tasks of a wheel arch of the motor vehicle.

In other words, the wheel arch segment may correspond to a part of the body which is arranged in the region of a wheel arch and thus in the region of a wheel of the motor vehicle and which catches dirt raised by the wheel during driving operation of the motor vehicle.

In a further advantageous further connection of the invention, the second guide element in the vehicle vertical direction above a rear wheel box is rotatably fixed to the body of the motor vehicle. This is advantageous because this results in a particularly favorable utilization of available space. A particular advantage is that this allows a movement of the vehicle door, for example, particularly far in the vehicle longitudinal direction to the rear, ie opposite to the direction of travel.

In a further advantageous further connection of the invention, the motor vehicle is designed as a convertible and the vehicle door as a rear door. This allows a particularly favorable utilization of available space on the convertible.

The convertible can be designed as a 4-door convertible, in other words as a convertible with four side doors. The convertible can be designed B-pillar-free (B-pillarless). In other words, it is possible to dispense with a vehicle pillar arranged between the rear door (rear side door) and a front door (front side door).
