Description

[0001] The invention relates to a door holding device for a door of a motor vehicle which is pivotable about a door pivot axis relative to a body of a motor vehicle according to the preamble of claim 1.

[0002] Door holding devices for doors, especially side doors, of motor vehicles are already well known in the general state of the art. Such a door holding device can be used, for example, in addition to door hinges, to ensure the door opens and closes in a defined manner. The door holding device allows the door to be locked in at least one open position, thus preventing, for example, the door from unintentionally pivoting from this open position into a closed position. A conventional door holding device has, for example, two spring-loaded sliding pieces, which are arranged or installed offset in the vertical direction (z-direction) of the vehicle. The sliding pieces are, for example, symmetrically designed.The sliding blocks can glide along a profiled support bar, also known as a door support bar, in accordance with the movement of the side door. By specifically profiling the door holding device, particularly the support bar, defined characteristics such as detents or engagement, force levels, and door closing energies can be set. However, a potential disadvantage is that, by its very nature, the sliding friction occurring as the blocks move along the support bar can result in particularly high closing energies that the user, i.e., a person, must exert to close the door. This means that the user has to apply a great deal of force to close the door, which can negatively impact the comfort of the vehicle.

[0003] Furthermore, DE 10 2005 030 699 A1 discloses a door stop for motor vehicles, comprising a door retaining rod, a holder housing with a through-opening for the door retaining rod and a locking unit arranged in the holder housing, wherein the locking unit has two pivotably mounted locking arms, each with a locking element, which are pre-tensioned towards each other and in the direction of the door retaining rod by a spring element, and wherein the locking elements bear against opposite sides of the door retaining rod and can be engaged with locking grooves on the door retaining rod.

[0004] Furthermore, a multi-stage door opening device is known from US Patent 5,474,344 A, which reliably holds the opened door at a desired opening angle and does not produce any operating noise when opening and closing the door.

[0005] The object of the invention is to create a door holding device for a door of a motor vehicle, so that the comfort of the motor vehicle can be increased in a particularly low-effort way.

[0006] This problem is solved according to the invention by a door holding device with the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0007] The invention relates to a door holding device for a motor vehicle door that can pivot about a door pivot axis relative to the body of a motor vehicle. The door holding device can be referred to as a door holding module or simply as a door holding device. Preferably, the motor vehicle, particularly in its fully manufactured state, has the door holding device. The motor vehicle is preferably designed as a motor vehicle, in particular as a passenger car or truck. The body is preferably designed as a unibody construction.

[0008] The door is preferably designed as a side door, that is, as a side door of the motor vehicle. Preferably, the door is pivotable about the door pivot axis relative to the body between a closed position and at least one open position, preferably several open positions. Furthermore, the door is preferably attached to the body, that is, for example, to at least one body component of the motor vehicle. For this purpose, the door has, for example, at least one fastening device by which the door is pivotable about the door pivot axis relative to the body, for example, between the closed position and the at least one open position, and in particular is attached to the body, especially to the body component, at least indirectly or directly. The body component is, for example, a vehicle pillar, in particular a door pillar.The fastening device is designed, for example, as a hinge, in particular as a door hinge. The door pivot axis runs, for example, at least substantially parallel to the vertical direction of the vehicle.

[0009] For example, in the closed position, a vehicle door opening is closed, in particular completely, by the door or by the door. In other words, in the closed position, the door opening is covered by the door, in particular completely. For example, in the open position, in particular the respective open position, the door opening is at least partially, in particular predominantly or completely, uncovered by the door. This means that in the open position, the closing or covering of the door opening is omitted. For example, the interior of a vehicle opens into the surrounding area via the door opening, particularly when the door is in the open position.This allows a person to enter the interior from the surrounding area through the door opening when the door is open, and / or a person to exit the vehicle through the door opening when the door is open, thereby accessing the surrounding area. This is not possible when the door is closed, meaning that in the closed position, a person cannot enter or exit the interior through the door opening. The interior, which can also be referred to as the vehicle interior, can be understood to mean, in particular, the passenger compartment or passenger cell.

[0010] The door holding device comprises a door retaining rod, which has at least one first attachment point by which the door retaining rod is held, in particular at least indirectly or directly, to a door part of the door. In other words, the door retaining rod can be attached to the door part of the door via the first attachment point, for example, by means of a hinge or a rigid connection. Furthermore, the door retaining rod has at least one second attachment point, in particular different from the first attachment point, by which the door retaining rod can be held, in particular at least indirectly or directly, to the body component of the motor vehicle that is formed separately from the door. In other words, the door retaining rod can be attached to the body component via the second attachment point, for example, by means of a hinge or a rigid connection. Preferably, the first and the second attachment points are spaced apart from each other.Furthermore, the door handle has at least one locking area, which, for example, has at least one locking contour.

[0011] Furthermore, the door holding device has at least one support element, in particular one designed separately from the door holding rod, which has at least one attachment area by which the support element can be held, in particular at least indirectly or directly, on the door part or the body component. In other words, the support element can be attached, for example rigidly, to the door part or the body component via the attachment area.

[0012] Furthermore, the door holding device has two rollers rotatably mounted on the support structure about their respective axes of rotation, in particular at least indirectly or directly. This means that the rollers are each rotatably mounted on the support structure about their respective axes of rotation, in particular at least indirectly or directly. Each roller is preferably designed as a roller bearing. The rotatability of each roller about its respective axis of rotation can be understood to mean, in particular, the rotatability of each roller about its respective axis of rotation relative to the door holding bar and / or relative to the support structure. The rollers are arranged on opposite sides of the door holding bar.This means that the first roller is arranged on a first side of the door handle, and the second roller is arranged on a second side of the door handle that differs from the first. In other words, the door handle extends, at least partially, between the rollers. The sides of the door handle are preferably opposite each other, and in particular, opposite sides. The axis of rotation of the first roller can be referred to as the first axis of rotation. The axis of rotation of the second roller can be referred to as the second axis of rotation.

[0013] Furthermore, the door holding device has at least one spring element, in particular designed separately from the rollers and the support structure, by means of which at least one of the rollers, for example the first roller, is movable along a direction of movement, in particular in the direction of movement, relative to the support structure, in particular at least indirectly or directly, coupled to the support structure, in particular by means of a spring or elastic coupling. In other words, the at least one of the rollers, for example the first roller, is movable or movable along the direction of movement relative to the support structure, or is attached to the support structure, for example at least indirectly or directly, wherein the roller is spring-loaded along the direction of movement via the spring element, that is, in particular, is spring-loaded and coupled to the support structure.In particular, the spring element is designed to press the at least one roller against the door handle, especially in or along the direction of movement, for example directly. This means that the roller can be pressed against the door handle by means of the spring element, especially in or along the direction of movement, for example directly. Thus, the spring element can ensure, for example, that the at least one roller, especially the first roller, rests against the door handle.

[0014] In the case of at least translational relative movement between the door handle and the support device, the rollers roll around their respective axis of rotation, particularly directly on the door handle. This means that, as a result of the transitory relative movement, especially through contact between the door handle and the respective roller, the rotation of the respective roller around its respective axis of rotation can be effected or is effected. In other words, the support device and the door handle are coupled or connected via the respective roller, that is, in particular through the rotation or rolling of the respective roller around its respective axis of rotation. The transitory relative movement results from the pivoting of the door, especially around its pivot axis.In other words, when the door pivots relative to the body around its pivot axis, a transient relative movement occurs between the door stay and the support mechanism. This means that the translational relative movement is caused by the pivoting of the door. During this translational relative movement, as the rollers roll around their respective pivot axis, at least one of the rollers, for example, the first roller, can be brought into engagement with the detent area, particularly directly, for example, in a positive-locking manner, in order to lock the door in the open position, that is, in at least one of the aforementioned open positions. The detent area is designed, for example, to correspond to the at least one roller. For example, the detent area is designed as a recess, in particular as a detent groove, as an edge, or the like.The locking area is formed, for example, by the door handle being profiled, at least in part. Locking the door in the open position, or one of its open positions, can be understood in particular as fixing or securing the door in the open position, or one of its open positions.

[0015] To significantly enhance the comfort of the motor vehicle, for example, the ease of closing the door, in a particularly cost-effective manner, the invention provides that, particularly in a first embodiment of the door holding device, one side of the door holding rod is a top side of the door holding rod, pointing upwards in the vehicle's vertical direction, and the other side of the door holding rod is a bottom side of the door holding rod, pointing downwards in the vehicle's vertical direction, particularly in the vehicle's vertical direction. Thus, for example, the first side, on which the first roller is arranged, is designed as the top side, and the second side, on which the second roller is arranged, is designed as the bottom side.In other words, the sides of the door support rod, that is, the sides on which the rollers are arranged, are designed as sides facing away from each other in the vehicle's vertical direction. Furthermore, the spring element is designed as a coil spring whose axial direction runs at least substantially parallel to the direction of movement. In other words, the coil spring has a deformation direction, which is defined in particular, along which the coil spring is deformable or is deformed, for example, when the at least one of the rollers is actuated and / or when the at least one of the rollers is actuated, in particular elastically, and the deformation direction runs at least substantially parallel to the direction of movement. The coil spring can be understood to be, in particular, a helical spring.

[0016] To significantly enhance the comfort of the motor vehicle, for example, the ease of closing the door, in a particularly cost-effective manner, the invention alternatively provides that, particularly in a second embodiment of the door holding device that differs from the first embodiment, the sides of the door holding rod, i.e., those sides on which the rollers are arranged, face away from each other in a direction perpendicular to the vehicle's vertical direction. This direction is, for example, a transverse direction of the vehicle (y-direction). Thus, one of the sides, particularly the first side, is, for example, an inner side of the door holding rod facing inwards in the transverse direction of the vehicle, especially when the door is in its closed position.Furthermore, the other side, in particular the second side, is, for example, the outer side of the door handle facing outwards in the transverse direction of the vehicle, especially when the door is in its closed position. Alternatively or additionally, the direction is, for example, the longitudinal direction of the vehicle. Thus, the sides of the door handle can face away from each other in the transverse direction and / or in the longitudinal direction of the vehicle.

[0017] The invention is based in particular on the following insights and considerations: The rollers, or rather the rolling motion of the rollers on the door handle during translational relative movement, allow for a particularly low level of mechanical friction between the rollers and the door handle, because, for example, rolling friction predominates and sliding friction can be avoided or at least kept to a minimum. This allows for a particularly low force required by the person to pivot the door around its pivot axis, especially when none of the rollers are engaged with the detent area, particularly in a positive-locking manner, i.e., when the door is not locked, i.e., free from any locking mechanism. This makes pivoting the door, for example opening and / or closing it, particularly comfortable for the person.In other words, a particularly reduced and therefore particularly pleasant closing force can be achieved by reducing friction. Compared to a conventional door holding device, the door holding device according to the invention can thus, in particular, for example, switch from sliding friction to rolling friction, using a plunger principle. This means that the door holding device according to the invention can be, or has been, redesigned in relation to the conventional door holding device, for example, by switching from a conventional plunger to roller bearings.

[0018] The coil spring element, with its axial direction parallel to the direction of movement, enables a particularly efficient, and for example, especially direct, force transmission from the spring element to the roller. This eliminates the need for additional components, and in particular, any additional pivoting mechanisms, thus significantly reducing the manufacturing effort required for the door holding device. The door holding device can therefore be manufactured with minimal effort. Because the sides of the door holding rod face away from each other in the direction perpendicular to the vehicle's vertical direction, the rollers can be positioned in a particularly space-saving manner within the door holding device. Furthermore, assembly can be greatly simplified.

[0019] In a further embodiment, particularly in the first embodiment, the respective axis of rotation, especially in the installed position of the door locking device in the motor vehicle, is arranged at least substantially horizontally. This means that the respective axis of rotation, particularly in the installed position of the door locking device in the motor vehicle, runs at least substantially parallel to the direction perpendicular to the vehicle's vertical direction. The horizontal arrangement of the respective axis of rotation can be understood, in particular, to mean that the respective axis of rotation extends at least substantially perpendicular to a plane that runs in the longitudinal and transverse directions of the vehicle, i.e., is defined by the longitudinal and transverse directions of the vehicle. The rollers, or rather their axes of rotation, can thus be arranged horizontally.The locking contour then runs, for example, at least substantially in the vertical direction of the vehicle. This means that the door retaining bar, especially the locking area, can be profiled in the vertical direction of the vehicle. The horizontal arrangement of the pivot axes allows for a particularly space-saving design of the door locking device. Furthermore, the door locking device can be designed to be particularly simple, thus keeping manufacturing costs to a minimum.

[0020] In a further embodiment, particularly in the door holding device according to the first embodiment, the movement mechanism is designed to have a translational direction of movement, which preferably runs at least substantially perpendicular to the respective axis of rotation. This means that the at least one roller is coupled to the support device in a translationally movable manner relative to the support device along the direction of movement. This allows for a particularly simple spring mechanism for applying pressure to the roller via the spring element, thereby significantly reducing the manufacturing effort of the door holding device.

[0021] In a further embodiment, particularly in the door holding device according to the first embodiment, it is provided that at least one of the rollers, for example the first roller, is rotatably mounted on a coupling element separately from the support structure about its axis of rotation, i.e., about the first axis of rotation, particularly relative to the coupling element. In other words, at least one of the rollers, for example the first roller, is rotatably mounted on the coupling element about its axis of rotation relative to the coupling element. Thus, the aforementioned mounting of at least one of the rollers, in particular the first roller, on the support structure can be effected by the coupling element.Furthermore, the coupling element is movable or movable via the spring element along the direction of movement, in particular translationally, for example at least indirectly or directly, to the support device, in particular by means of springs or elastics. In other words, the coupling element is movably held on the support device along the direction of movement, in particular translationally, wherein the coupling element is spring-loaded to the support device in the direction of movement, in particular translationally, via the spring element. This allows the roller to be mounted on the support device in a particularly simple and / or particularly reliable manner.

[0022] In a further embodiment, particularly in the first embodiment, the coupling element, and especially the spring element, is / are guided movably in the support device along the direction of movement. In other words, the coupling element is movably mounted on or in the support device in the direction of movement. This allows the coupling element to be guided particularly securely and / or with particular precision. Preferably, the coupling element rests directly against the support device. Preferably, the spring element is held against the coupling element, so that when the coupling element moves in the direction of movement, at least a part of the spring element can move along with the coupling element.

[0023] In a further embodiment, the coupling element, particularly in the first embodiment, is pivotable about a coupling element pivot axis relative to the support device and / or relative to the door holding rod. In other words, the coupling element is pivotable or rotatable about the coupling element pivot axis, and is mounted, in particular, on or in the support device. This allows the roller, especially the first roller, to pivot along with the coupling element about the coupling element pivot axis. This significantly increases flexibility with regard to the shape of the door holding rod, especially the locking area, so that the door holding rod can, for example, be curved and / or the first roller can roll along the door holding rod in an arc-shaped path. This allows the door holding device to be designed in a particularly space-saving manner.The coupling element pivot axis can also be referred to as the first coupling element pivot axis. The coupling element pivot axis preferably runs parallel, and in particular coaxially, to the direction of movement.

[0024] In a further embodiment, the door holding device, particularly in the first embodiment, has a second spring element, which is designed separately from the first spring element. This second spring element allows the other roller, for example, the second roller, to be movably coupled to the support structure along the direction of movement, particularly at least indirectly or directly, and in particular by means of a spring or elastic connection. The second spring element is preferably designed as a coil spring whose axial direction is parallel to the direction of movement. The rollers and the spring elements can thus be arranged on both sides of the support structure, thereby enabling a particularly reliable locking mechanism for the door in at least one of the open positions.

[0025] In a further embodiment, particularly in the second embodiment of the door holding device, the respective axis of rotation, especially when the door holding device is installed in the vehicle, runs at least substantially parallel to the vehicle's vertical direction. In other words, the rollers or their axes of rotation are arranged or oriented vertically in the vehicle. The locking contour extends, for example, in the longitudinal or transverse direction of the vehicle. In other words, the door retaining bar is designed, for example, as a profiled door retaining bar in the longitudinal or transverse direction of the vehicle. This allows the overall height of the door holding device to be kept particularly low.

[0026] Preferably, particularly in the case of the door holding device according to the second embodiment, the direction of movement is rotary. This means that at least one of the rollers is rotatably coupled to the support device along the direction of movement relative to the support device via the at least one spring element. This ensures, in a particularly cost-effective and / or reliable manner, that the roller remains in contact with the door holding rod, especially at all times.

[0027] In a further embodiment, particularly in the door holding device according to the second embodiment, it is provided that at least one of the rollers, for example the first roller, is rotatably mounted on a coupling element separately from the support structure about its axis of rotation, particularly at least indirectly or directly, especially relative to the coupling element. In other words, at least one of the rollers, particularly the first roller, is rotatably mounted on the coupling element about its axis of rotation. The coupling element is spring-loaded along the direction of movement, particularly at least indirectly or directly, and coupled to the support structure. In other words, the coupling element is movably mounted on the support structure along the direction of movement and is spring-loaded to the support structure in the direction of movement via the spring element. This allows the roller to be mounted in a particularly simple and / or particularly secure manner.

[0028] In a further embodiment, particularly in the door holding device according to the second embodiment, it is provided that when the roller, which is held in particular on the coupling part, is moved relative to the support device along the direction of movement, the roller pivots about a pivot axis. This means that the aforementioned movement of the roller relative to the support device along the direction of movement is the pivoting of the roller about the pivot axis relative to the support device. The roller is arranged eccentrically with respect to the pivot axis. In other words, the axis of rotation of the roller, for example in the longitudinal direction of the vehicle and / or in the transverse direction of the vehicle, is spaced apart from the pivot axis. This allows the roller to always be held in its desired position on the door holding rod, so that, for example, the roller is always in contact with the door holding rod, preferably spring-loaded.

[0029] In a further embodiment, particularly in the door holding device according to the second embodiment, the spring element is designed as a torsion spring. A torsion spring can be understood to be, in particular, a torsion spring. This allows the manufacturing effort of the door holding device to be kept particularly low. Furthermore, the contact of the roller with the door support bar can be achieved with minimal effort and / or with particular security.

[0030] A first further aspect relates to a motor vehicle which has at least one door holding device according to the invention. Advantages and advantageous embodiments of the invention are to be regarded as advantages and advantageous embodiments of the first further aspect and vice versa.

[0031] A second further aspect relates to a method for operating the motor vehicle, in particular a method for pivoting the door of the motor vehicle about the door pivot axis, and / or a method for operating a door holding device according to the invention. Advantages and advantageous embodiments of the invention are to be regarded as advantages and advantageous embodiments of the first and the second further aspect, and vice versa.

[0032] The invention also includes combinations of the features of the described embodiments. The invention therefore also includes realizations that each exhibit a combination of the features of several of the described embodiments, provided that the embodiments have not been described as mutually exclusive.

[0033] The following are exemplary embodiments of the invention described.

[0034] The exemplary embodiments described below are preferred embodiments of the invention. In these exemplary embodiments, the described components each represent individual features of the invention, which can be considered independently of one another and each further develops the invention independently. Therefore, the disclosure is intended to include combinations of features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0035] In the figures, identical reference symbols denote functionally equivalent elements.

[0036] Fig. Figure 1 shows a schematic partial sectional view of a door holding device 1 for a Fig. 1 Door not shown, in particular a side door, of a motor vehicle. Fig. Figure 2 shows the door holding device 1 according to Fig. 1 in a further schematic partial sectional view. The door, which can also be referred to as a vehicle door, is pivotable about a door pivot axis relative to the body of the motor vehicle, for example between a closed position and an open position or several open positions, and is held in particular against the body. The door holding device 1 is designed separately from the body and separately from the door.

[0037] The door holding device 1 has a door retaining bar 2, which has a first attachment point 3, via which the door retaining bar 2 is attached to a Fig. 1 or Fig. The door retaining rod 2 has a second attachment point 4, which is spaced apart from the first attachment point 3, by means of which the door retaining rod 2 is to be held or is to be held on a body part of the vehicle body or motor vehicle that is formed separately from the door. The body part is in Fig. 1 and Fig. 2 is also not shown. For example, at least one of the fastening points 3, 4 is designed as a bearing that can be pivoted about a bearing pivot axis 6. In the Fig. In the embodiment shown in Figure 1, the second mounting point 4 is designed as a bearing, whereby the door support rod 2 is pivotably held or held on the body component or the body via the second mounting point 4 about the bearing pivot axis 6 relative to the body component or the body. For this purpose, at least one mounting element 7 is arranged or provided on the body side, i.e., for example, on the body component, which is pivotably connected to the door support rod 2 about the bearing pivot axis 6 relative to the second mounting point 4, and in particular is directly coupled to the door support rod 2. For example, the bearing pivot axis 6 runs parallel to the door pivot axis. Preferably, the bearing pivot axis 6 is spaced apart from the door pivot axis.

[0038] Furthermore, the door handle 2 has at least one locking area 8. For example, the door handle 2 has a second locking area 9, which is distinct from the locking area 8, wherein, for example, the locking area 8, also referred to as the first locking area, is arranged on a first side 10 of the door handle 2 and the second locking area 9 is arranged on a second side 11 of the door handle 2, facing away from the first side 10. The respective locking areas 8, 9 have, for example, at least one locking contour, but preferably several locking contours. These locking contours are in Fig. 1 and Fig. However, 2 is not shown. For example, the respective grid contour is a respective depression, an respective edge, or the like.

[0039] Furthermore, the door holding device 1 has a support device 12, which is separate from the door retaining rod 2 and has at least one mounting area 13 by means of which the support device 12 is held or is held on the door part of the door or the body component, or the body itself, in this case, the door part. For example, the support device 12 is screwed to the door part or the body component via the mounting area 13. The support device 12 has, for example, a first support device part 14 and a second support device part 15. The support device parts 14 and 15 are, for example, formed separately from each other or integrally formed together. For example, the first support device part 14 is arranged on the first side 10 and the second support device part 15 is, for example, arranged on the second side 11.

[0040] Furthermore, the door holding device 1 has two rollers 18, 19 rotatably mounted on the support device 12 about respective axes of rotation 16, 17. Thus, for example, a first roller 18 is rotatable about a first axis of rotation 16, and the second roller 19 is rotatable about a second axis of rotation 17. The axes of rotation 16, 17 preferably run parallel to each other. The rollers 18, 19 are arranged on opposite sides 10, 11 of the door holding rod 2. In this case, the first roller 18 is arranged on the first side 10, and the second roller 19 is arranged on the second side 11. In the Fig. In the embodiment shown in Figure 1, the first roller 18 is rotatably mounted on the first support element 14 about the first axis of rotation 16, and the second roller 19 is rotatably mounted on the second support element 15 about the second axis of rotation 17. Preferably, each roller 18, 19 is designed as a rolling bearing or as at least a part of a rolling bearing.

[0041] Furthermore, the door holding device 1 has at least one spring element 20, via which at least one of the rollers 18, 19 is movably coupled to the support device 12 along a direction of movement 22 relative to the support device 12. In the Fig. 1 and Fig. In the embodiment shown in Figure 2, however, two such spring elements 20, 21 are provided. This means that the door holding device 1, for example, has the two spring elements 20, 21. The first roller 18 is movably coupled to the support device 12 along the direction of movement 22 relative to the support device 12 via a first spring element 20. The second roller 19 is movably coupled to the support device 12 along the direction of movement 22 relative to the support device 12 via the second spring element 21. The first spring element 20 is, for example, arranged on the first side 10 and the second spring element 21 is, for example, arranged on the second side 11. In particular, the first spring element 20 is received in the first support device part 14 and the second spring element 21 is, in particular, received in the second support device part 15.The direction of movement 22 runs, for example, parallel to the bearing pivot axis 6 and / or parallel to the door pivot axis. Preferably, the respective roller 18, 19, particularly on its respective side 10, 11, can be pressed against the door retaining rod 2, particularly against the respective detent area 8, 9, by means of the respective spring element 20, 21. In particular, the respective roller 18, 19 is subjected to force, or can be subjected to force, by the respective spring element 20, 21 at least indirectly along the direction of movement 22 in the direction towards the door retaining rod 2, in particular to press the respective roller 18, 19 against the door retaining rod 2. The respective spring element 20, 21 can therefore also be referred to as a compression spring.

[0042] During a translational relative movement between the door support rod 2 and the support device 12, the rollers 18, 19 roll about their respective axes of rotation 16, 17, that is, they roll about their respective axes of rotation 16, 17, on the door support rod 2, particularly in or on the respective detent area 8, 9. Thus, the rolling can be understood to mean, in particular, the rolling of the respective roller 18, 19 on its respective side 10, 11. Furthermore, the respective detent area 8, 9 can be understood to mean, in particular, a respective rolling area provided for the rolling or rolling along the respective roller 18, 19, wherein, as explained above, this respective rolling area has, for example, at least one detent contour, but preferably several such detent contours. The translational relative movement results from the pivoting of the door about the door pivot axis. In the Fig. 1 and Fig. In the embodiment shown in Figure 2, the translational relative movement is oblique or perpendicular to the direction of movement 22. Through this translational relative movement, or through the rolling of the rollers 18, 19 about their respective axes of rotation 16, 17 on the door support rod 2, at least one of the rollers 18, 19 can be brought into, in particular direct, engagement with the locking area 8, 9, in particular with the locking contour or one of the locking contours, in order to lock the door in at least one of the open positions. Preferably, however, the first roller 18 can be brought into engagement with the first locking area 8, in particular with one of the locking contours arranged therein, and the second roller 19 can be brought into engagement with the second locking area 9, in particular with one of the locking contours arranged therein, in order to lock the door in the at least one open position.This allows the respective roller 18, 19 to engage with the respective detent area 8, 9, in particular the respective detent contour, thereby locking the door in at least one open position. This locking, or the aforementioned engagement, is preferably reversibly releasable, so that, for example, if an actuating force for pivoting the door about the pivot axis is greater than a predetermined or predefined threshold value, the door can be pivoted out of the locked open position about the pivot axis, since in particular the respective engagement of the respective roller 18, 19 with the respective detent area 8, 9 is releasable.It is therefore specifically intended that when the door pivots about the door pivot axis, at least one of the rollers 18, 19 is engaged with the respective detent area 8, 9 in order to lock the door in at least one open position.

[0043] In Fig. 1 and Fig. Figure 2 shows the door holding device 1 according to a first embodiment. To significantly increase the comfort of the motor vehicle in a particularly cost-effective manner, in the first embodiment, one of the sides 10, 11 (here, the first side 10) is a top surface 24 of the door holding rod 2, pointing upwards in the vehicle's vertical direction 23, and the other of the sides 10, 11 (here, the second side 11) of the door holding rod 2 is a bottom surface 25 of the door holding rod 2, pointing downwards in the vehicle's vertical direction 23. The respective spring element 20, 21 is designed as a coil spring 26, 27, the axial direction 28, 29 of which is parallel to the direction of movement 22. For example, the axial direction 28, 29 is at least substantially parallel to the vehicle's vertical direction 23 and / or perpendicular to the translational relative movement. Thus, the respective spring element 20, 21 is oriented perpendicular to the door holding rod 2.The axial direction 28 of the first spring element 20 can be referred to as the first axial direction 28. Furthermore, the axial direction 29 of the second spring element 21 can be referred to as the second axial direction 29.

[0044] In the first embodiment, the respective axis of rotation 16, 17 is arranged at least substantially horizontally, particularly within the motor vehicle. The respective axis of rotation 16, 17 can therefore be understood as a respective horizontal roller axis. The door retaining rod 2, in particular the respective locking area 8, 9, is profiled, for example, in the vehicle's vertical direction 23, especially to form the respective locking contour. The respective axis of rotation 16, 17 preferably runs obliquely or perpendicularly to the door pivot axis, the bearing pivot axis 6, and / or the direction of movement 22. In particular, the respective axis of rotation 16, 17 runs at least substantially obliquely or perpendicularly to the vehicle's vertical direction 23, for example, parallel to a transverse or longitudinal direction of the motor vehicle.

[0045] In the first embodiment, the direction of movement 22 is a translational direction of movement, which preferably runs perpendicular to the respective axis of rotation 16, 17. Furthermore, the direction of movement 22 runs in particular perpendicular to an extension direction of the respective side 10, 11 of the door support bar 2.

[0046] In the first embodiment, at least one of the rollers 18, 19, for example the first roller 18, is rotatably mounted on a coupling element formed separately from the support device 12 about its respective axis of rotation 16, 17, that is, in this case about the first axis of rotation 16. Furthermore, the coupling element 30 is movably coupled to the support device 12, in particular the first support device part 14, via the first spring element 20 along the direction of movement 22, and in particular directly. Specifically, the coupling element 30, which can also be referred to as the first coupling element 30, is movably mounted in the support device 12, in particular the first support device part 14, along the direction of movement 22 relative to the support device 12. In other words, the first coupling element, and in particular the first spring element 20, is movably guided in the support device 12 along the direction of movement 22.In this embodiment, the second roller 18 is rotatably mounted about the second axis of rotation 17 on a second coupling element 31, which is separate from the support device 12 and separate from the first coupling element 30. Furthermore, the second coupling element 31 is movably coupled to the support device 12, particularly the second part of the support device 15, via the second spring element 21 along the direction of movement 22, and in particular directly. Specifically, the second coupling element 31 is accommodated in the support device 12, particularly in the second part of the support device 15, so that it is translationally movable relative to the support device 12 along the direction of movement 22. In other words, the second coupling element 31, and in particular the second spring element 21, is movably guided in the support device 12 along the direction of movement 22.Thus, for example, the first coupling element 30 is arranged on the first side 10 and the second coupling element 31 is arranged on the second side 11. In particular, the first coupling element 30 is associated with the first spring element 20 and the first roller 18. In particular, the second coupling element 31 is associated with the second spring element 21 and the second roller 19. In the present case, the respective coupling element 30, 31 extends at least partially between the respective spring element 20, 21 and the respective roller 18, 19, whereby the respective roller 18, 19 is coupled to the respective spring element 20, 21 via the respective coupling element 30, 31. For example, the respective coupling element 30, 31 is designed as a respective plunger and / or as a respective spring end piece, in particular with a roller carrier.For example, the respective spring element 20, 21 is directly coupled to the respective coupling element 30, 31, whereby a spring force caused or provided by the respective spring element 20, 21 can act directly on the respective coupling element 30, 31, which is designed, for example, as the respective spring end piece. This respective spring force preferably acts perpendicular to the respective detent area 8, 9, preferably perpendicular to the respective detent contour, that is, in particular to a respective orientation of the respective detent contour.

[0047] For example, the first coupling element 30 is pivotable about a first coupling element pivot axis 30a relative to the support device 12. For example, the second coupling element 31 is pivotable about a second coupling element pivot axis 30b relative to the support device 12. The coupling element pivot axes 30a and 30b preferably run parallel, and in particular coaxially, to each other. Preferably, the first and / or the second coupling element pivot axis 30a and 30b runs parallel to the direction of movement 22.

[0048] In this embodiment, two spaced-apart guide elements 43, 44 are arranged on the first side 10 of the door handle 2, between which the first roller 18 is arranged. The guide elements 43, 44 are in Fig. Figure 3 shows a schematic partial sectional view of the door holding device 1 according to the first embodiment. The guide elements 43, 44 are provided, in particular, for guiding the first coupling element 30. For example, the guide elements 43, 44 preferably bear against the first coupling element 30 on both sides, and especially directly against it. The guide element 43 can be referred to as the first guide element 43. The guide element 44 can be referred to as the second guide element 44. The respective guide element 43, 44 can be understood, in particular, as a respective leading edge, especially one provided for the first coupling element 30. For example, the respective guide element 43, 44 is designed as a respective projection of the door retaining bar 2.

[0049] For example, on the second side 11 of the door handle 2, two spaced-apart guide elements 45, 46 are arranged, between which the second roller 19 is arranged. The guide elements 45, 46 are provided, in particular, for guiding the second coupling element 31. For example, the guide elements 45, 46 bear against the second coupling element 31, preferably on both sides, and especially directly. The guide element 45 can be referred to as the third guide element 43. The guide element 46 can be referred to as the fourth guide element 46. The respective guide element 45, 46 can be understood, in particular, as a respective leading edge, especially one provided for the second coupling element 31. For example, the respective guide element 45, 46 is designed as a respective projection on the door handle 2.

[0050] The guide elements 43, 44 are in Fig. 4 is particularly easy to see, in which the door holding device 1 according to the first embodiment is shown in a schematic and perspective partial view viewed obliquely from above. As also in Fig. As can be seen in Figure 4, the door holding rod 2, in particular the first and / or the second locking area 8, is designed, for example, at least partially, in an arc shape, so that, for example, the first roller 18 and / or the second roller 19 can roll along the door holding rod 2 in an arc shape, in particular in each case. This allows the door holding device 2 to be designed in a particularly space-saving manner.

[0051] Furthermore, as in Fig. Figure 4 illustrates that on the first and / or second side 10, 11, in particular in the first and / or second locking area 8, 9, a locking profile 47 is formed, which, for example, has raised sections and / or depressions. The locking profile 47, in particular the raised sections and / or depressions, is designed for engagement, in particular for locking, with the first and / or second roller 18, 19. These raised sections and / or depressions form, in particular, the aforementioned locking contours.

[0052] Fig. Figure 5 shows a schematic perspective view of the door holding device 1 according to a second embodiment, which differs from the first embodiment. In the second embodiment, the sides 10 and 11 of the door holding rod 2 face away from each other in a direction 33 perpendicular to the vehicle's vertical direction 23. This direction 33 is, for example, the transverse direction of the vehicle. Thus, for example, one of the sides 10 or 11, in particular the first side 10, is designed as an inner side facing inwards in the transverse direction of the vehicle, and the other of the sides 10 or 11, for example the second side 11, is designed as an outer side facing outwards in the transverse direction of the vehicle. Furthermore, as shown in Fig. Figure 5 illustrates that on the first and second sides 10, 11, in particular in the first and second locking areas 8, 9, a respective locking profile 42 is formed, which, for example, has raised sections and / or depressions. The locking profile 42, in particular the raised sections and / or depressions, is designed for engagement, in particular for locking, with the respective roller 18, 19. These raised sections and / or depressions form, in particular, the aforementioned locking contours.

[0053] In the second embodiment, the respective axis of rotation 16, 17 preferably runs at least substantially parallel to the vehicle's vertical direction 23. Thus, in the second embodiment, the rollers 18, 19 and their axes of rotation 16, 17 are arranged vertically. Furthermore, preferably, as in Fig. As can be seen in Figure 5, the door retaining bar 2, particularly on both sides, is designed as a door retaining bar 2 profiled in direction 33, particularly in the transverse direction of the vehicle, in particular to form the aforementioned locking contours. Furthermore, in the second embodiment, the direction of movement 22 is preferably a rotational direction of movement. One axis of rotation of the direction of movement 22 runs, for example, at least substantially parallel to the vertical direction of the vehicle 23.

[0054] Furthermore, in the second embodiment, at least one of the rollers 18, 19, in this case the first roller 18, is movably coupled to the support device 12 via the spring element 20 along the direction of movement 22, i.e., rotationally, at least indirectly, and in particular directly, relative to the support device 12. The spring element 20 is designed as a torsion spring 34, which can be referred to as a rotation spring. An axis extending in the axial direction of the spring element 20, which can be understood in particular as a rotation axis of the torsion spring 34, runs, for example, at least substantially parallel to the respective axis of rotation 16, 17 and / or parallel to the bearing pivot axis 6 and / or parallel to the door pivot axis. Preferably, this axis of rotation is spaced apart from the bearing pivot axis 6 and / or the door pivot axis.The axis of rotation is, for example, arranged coaxially to the axis of rotation of the direction of movement 22.

[0055] For example, with regard to the spring elements 20, 21, only the first spring element 20 is provided in the second embodiment, whereby the second embodiment of the door holding device 1 is, for example, free of the second spring element 21, and in particular free of further spring elements. This allows the manufacturing effort for the door holding device 1 to be kept particularly low.

[0056] Preferably, in the door holding device 1 according to the second embodiment, at least one of the rollers 18, 19 is rotatably mounted on a coupling part 35, which is separate from the support device, about its respective axis of rotation 16, 17. In this case, this applies to the first roller 18, whereby the first roller 18 is rotatably mounted on the coupling part 35 about the first axis of rotation 16, at least indirectly, and in particular directly. In this case, the coupling part 35 is pivotable about a pivot axis 36 relative to the support device 12 and / or relative to the door holding rod 2, for example, directly, on the support device 12, in particular on the first and the second support device parts 14, 15. The pivot axis 36 is preferably arranged coaxially with the aforementioned axis of rotation. In particular, the coupling part 35 is preferably pivotable about the pivot axis 36 and is received in the support device 12.The coupling element 35 is preferably held or fastened to the support device 12 by means of a connecting element 37, which is, for example, designed as a pin. The connecting element 37 is, for example, arranged coaxially to the pivot axis 36. For example, the connecting element 37 is pivotably held about the pivot axis 36 relative to the support device 12 on the support device 12, in particular directly, for example, on the first support device part 14 and the second support device part 15. For example, the connecting element 37 is rotationally fixed, in particular directly, to the coupling element 35.

[0057] Furthermore, the coupling part 35 is sprung along the direction of movement 22, i.e. in particular rotationally, via the spring element 20 or by means of the spring element 20, and is coupled to the support device 12, in particular to the first and the second support device part 14, 15, preferably by means of the connecting part 37.

[0058] In the Fig. In the embodiment shown in Figure 5, the connecting part 37, which is designed in particular as a pin, extends at least partially through the support device 12, wherein, for example, a first length section of the connecting part 37 is arranged on a first side of the support device 12 and a second length section of the connecting part 37, different from the first length section, is arranged on a second side of the support device 12, different from the first side of the support device 12. For example, the first side of the support device 12 is an upper surface of the support device 12 pointing upwards in the vehicle direction 23 and the second side of the support device 12 is, for example, an underside of the support device 12 pointing downwards in the vehicle direction 23.Furthermore, the torsion spring 34 in the present case has two torsion spring sections 38, 39, wherein a first torsion spring section 38 is coupled, in particular directly, to the first length section of the connecting part 37 and the second torsion spring section 39 is coupled or connected, for example, in particular directly, to the second length section of the connecting part 37.

[0059] For example, the torsion spring sections 38, 39 are formed in one piece together, in particular connected to each other via a connection area 40 of the torsion spring 34.

[0060] Preferably, the movement of the first roller 18 relative to the support device 12 and / or relative to the door support rod 2 along the direction of movement 22 is accompanied by a pivoting of the first roller 18 about the pivot axis 36. This means that, in this case, the coupling part 35 is pivoted or is pivoted about the pivot axis 36, whereby the first roller 18 is pivoted or can be pivoted together with the coupling part 35 about the pivot axis 36. In this case, the first roller 18 is arranged eccentrically with respect to the pivot axis 36. Thus, the first axis of rotation 16 is spaced apart from the pivot axis 36.

[0061] As in Fig. As shown in Figure 5, for example the second roller 19 is rotatably mounted on the support device 12 via a fastening part 41 about the second axis of rotation 17, preferably without springs.

[0062] Overall, the examples demonstrate how a door stop with a roller-guided plunger can be provided. Friction at the door stop can thus be reduced, particularly through the use of rollers 18 and 19. Targeted clamping forces, which a sliding plunger can inherently achieve, for example, for stepless positioning in specific door opening ranges, can be replicated in the present roller-based system, for example, via multiple detents, meaning not entirely stepless. The diameter of each roller 18 or 19 is, for example, at least substantially 8 mm. The static load rating of each roller 18 or 19 is, for example, at least substantially 137 kN.
