[0001] Locking device with an adjustable connecting element

[0002] Description

[0003] The invention relates to a closure device according to the preamble of claim 1.

[0004] Such a closure device comprises a first closure part having a first body, an engagement device arranged on the first body, and a first magnetic device, and a second closure part having a second body, a connecting element movably arranged on the second body, and a second magnetic device arranged on the connecting element. To close the closure device, the first closure part and the second closure part can be placed against one another. In a closed position, the connecting element engages with the engagement device to hold the first closure part and the second closure part against one another. To open the closure device, the engagement between the connecting element and the engagement device can be released, so that the first closure part and the second closure part can be separated from one another.

[0005] In the closure device, the connecting element on the second body of the second closure part is adjustable between an initial position, in which the connecting element is at least partially received in the body, and a functional position, and in the functional position, protrudes relative to the second body, so that the connecting element can be brought into engagement with the engagement device of the first closure part. The first magnetic device and the second magnetic device are designed to interact in a magnetically attractive manner when the first closure part and the second closure part approach one another, in order to transfer the connecting element from the initial position to the functional position.

[0006] In a closure device known from DE 10 2010 044 198 A1, spring locking elements are arranged on a closure part, which, in a closed position, engage with engagement elements of another closure part. The engagement elements are accommodated in a housing of the other closure part in an initial position, so that in the initial position the engagement elements do not protrude outward from the housing or protrude only slightly. From the initial position, the engagement elements can be adjusted relative to the housing, so that in a functional position the engagement elements protrude from the housing and can be engaged with the spring locking elements to connect the closure parts.

[0007] A locking device known from US 6,659,516 for locking a laptop computer in a closed position has a hook element which is received in an initial position in an associated housing and can be pivoted out of the housing for locking.

[0008] In a locking device, such as that known from DE 10 2010 044 198 A1, engagement elements on one locking part are extended when locking parts approach each other, in order to engage with spring locking elements on another locking part in a closed position and to establish a connection between the locking parts in the closed position. The engagement elements are pre-tensioned, for example, spring-elastically, relative to a body of the associated locking part in the direction of the initial position, which results in the locking parts being in pre-tensioned contact with each other in the closed position.

[0009] For example, when using a closure device in a vehicle, for example on a padded surface, it may be desirable for the closure parts to not be in contact with each other over a large area in a closed position, in order to enable a reliable connection between the closure parts even on irregularly shaped surfaces, for example, on padded surfaces. The object of the present invention is to provide a closure device that can be used variably and enables a reliable connection of closure parts, even on irregularly shaped surfaces, for example.

[0010] This object is achieved by an article having the features of claim 1.

[0011] Accordingly, the connecting element is pivotable about a rotation axis relative to the second body in order to adjust the connecting element into the functional position in an adjustment direction directed about the rotation axis, wherein the connecting element in the closed position is positively engaged with the engagement device of the first closure part in such a way that a movement of the connecting element counter to the adjustment direction relative to the first closure part is blocked due to the positive engagement.

[0012] To close the closure device, the closure parts of the closure device are brought closer together, for example along a closing direction. Due to the magnetic interaction of the magnetic devices on the side of the first closure part and the connecting element of the second closure part, when the closure parts approach each other, the connecting element of the second closure part is moved from the starting position into the functional position. While the connecting element is fully or partially enclosed in the body of the associated second closure part in the starting position, the connecting element is adjusted relative to the body of the second closure part in the functional position such that the connecting element protrudes from the body and can thus be brought into engagement with the engagement device on the first closure part.

[0013] However, the adjustment of the connecting element from the starting position to the functional position when closing the closure device does not occur linearly, but rather about a rotational axis. The connecting element can be pivoted about the associated rotational axis relative to the body and can thus, in order to transfer it from the starting position to the functional position, be pivoted relative to the body of the second closure part like a lever element. In the starting position, the connecting element is, for example, fully or partially enclosed in the body of the second closure part. In the functional position, in contrast, the connecting element protrudes relative to the body of the second closure part such that the connecting element can be brought into engagement with the engagement device of the first closure part and thus a connection can be established between the closure parts.

[0014] The technical advantage of an adjustment around a rotational axis is particularly due to the simple realization of a precise, virtually play-free fixing of the locking parts.

[0015] When the locking parts are brought closer together to close the locking device, the connecting element is pivoted out of its initial position due to the magnetic attraction between the magnets. Once the connecting element has been moved into the functional position, the connecting element can be brought into engagement with the engagement device, so that the locking parts are held together in the closed position.

[0016] In the closed position, the connecting element is locked to the first closure part in such a way that the connecting element cannot be adjusted relative to the body of the first closure part counter to the adjustment direction pointing around the axis of rotation, in which direction the connecting element has been pivoted to transfer it into the functional position. With respect to the adjustment direction, the connecting element is thus fixed to the first closure part in the closed position, so that the connecting element is locked in its position with respect to the adjustment direction relative to the first closure part. Due to the engagement with the engagement device, the connecting element cannot be moved from the functional position back into the starting position when the closure device is in the closed position, at least not without the engagement between the connecting element and the engagement device of the first closure part being released.

[0017] This applies in particular if the first closure part is held in a fixed position relative to the second closure part in the closed position, for example because the first closure part is in contact with the second closure part or the connection is established by several (at least two) spatially distributed connecting elements. In this case, the connecting element can no longer be moved relative to the second closure part due to the engagement of the connecting element with the engagement device of the first closure part.Because the connecting element is pivotable about a rotational axis (preferably perpendicular to a closing direction) relative to the body of the second closure part and thus has to be pivoted about the rotational axis for transferring from the starting position to the functional position (or vice versa from the functional position to the starting position), the connecting element performs an adjustment movement for transferring between its different positions that is not linearly directed along the closing direction and thus differs from the closing direction. The adjustability of the connecting element along the adjustment direction, which differs from the closing direction, can be exploited to lock the connecting element in its position (also) relative to the body of the second closure part when the locking device is in the closed position.Thus, in the closed position, due to the engagement of the connecting element with the engagement device, movement of the connecting element counter to the adjustment direction (directed around the axis of rotation) can also be blocked relative to the second body of the second closure part if the closure parts are held fixedly in position relative to one another in the closed position. Due to the blocking effect, the connecting element cannot move along the adjustment direction relative to the body of the second closure part when the closure device is in the closed position and the connecting element is engaged with the engagement device of the first closure part. Because movement along the adjustment direction is blocked, the connecting element is fixed in its functional position relative to the body of the second closure part, such that the connecting element cannot be adjusted out of the functional position.This ensures that, in the closed position, the connecting element engages with the engagement device of the first closure part, thereby establishing the connection between the closure parts, but the body of the second closure part is not necessarily in contact with the body of the first closure part. By locking the connecting element in the functional position with the closure device in the closed position, the bodies of the closure parts can be kept at a distance from one another, thus preventing surface contact between the bodies of the closure parts.

[0018] This makes it possible, in particular, to create a secure and reliable connection between the closure parts, even in the case of irregularly shaped surfaces of the bodies of the closure parts, for example in the case of a padded surface on a body, which connection is independent of the shape of the surfaces of the bodies of the closure parts. Signs of wear, for example scratches or abrasion marks, on a padded surface, for example, can be avoided in this way. In one embodiment, the first closure part and the second closure part can be brought closer together along a closing direction in order to close the closure device, wherein the axis of rotation is directed at least approximately perpendicular to the closing direction. The closure parts can, for example, be attachable to one another exclusively along the closing direction (at least over the final part of the closing path).In another embodiment, the closure parts can also be placed together along the closing direction and also along other directions, for example transversely to the closing direction, in order to close the closure device, so that the approachability of the closure parts to one another is not limited to the closing direction.

[0019] In one embodiment, the connecting element can be pivoted relative to the second body for transferring from the initial position into the functional position, for example by an angle between 20° and 150°, preferably between 30° and 100°, for example 45° or 90°.

[0020] The second closure part can, for example, be arranged on a (quasi-)stationary assembly, for example in a vehicle, for example on a vehicle seat. In the initial position, the connecting element is, for example, fully or partially received in the body of the second closure part, so that in the initial position corresponding to a non-use position, the connecting element does not protrude outwards and is therefore not a hindrance and, moreover, does not impair the aesthetic external appearance of the associated assembly. The first closure part, on the other hand, can be arranged on an assembly that is to be fixed in a vehicle, for example on an electrical or electronic assembly such as a mobile phone or a navigation device or on a holding device such as a storage compartment, a coat hanger, a table or the like.When the closure parts approach each other, the connecting element is moved from the starting position into the functional position so that the closure parts can be fastened to each other and thus the first closure part is held in position on the second closure part in the closed position of the closure device.

[0021] In one embodiment, the connecting element has a head that is held in a form-fitting manner on the engagement device in the closed position. In the closed position of the closure device, the connecting element protrudes with the head relative to the body of the second closure part and engages the engagement device of the first closure part, so that the closure parts are secured to one another in a form-fitting manner.

[0022] The head of the connecting element can, for example, have an engagement projection forming an undercut, which engages with the engagement device in the closed position, so that the connecting element engages the engagement device in a form-fitting manner, in particular with respect to the closing direction.

[0023] In one embodiment, the second body of the second closure part forms a surface which, in the closed position, faces the first closure part, wherein the head is substantially flush with the surface in the initial position and is spaced from the surface in the functional position, preferably viewed along the closing direction. In the initial position, the connecting element is received in the body of the second closure part such that the head does not protrude outwards, or only protrudes insignificantly, relative to the surface of the second body, but is substantially flush with the surface. The surface is not necessarily flat but can, for example, be curved, in which case the head of the connecting element can have a shape that continues the shape of the surface and is thus flush with the surface.In the initial position, the second closure part thus has a self-contained shape on its outwardly facing surface, without the connecting element protruding in a disturbing manner from the body of the second closure part.

[0024] In this case, substantially flush means that no sharp-edged areas of the connecting element protrude from the surface and there is no risk of injury to a user, for example in the event of a collision in a vehicle or in the event of contact, for example when a vehicle occupant gets into a vehicle.

[0025] For example, the substantially flush arrangement can create a visual unity between the surface of the second body and the visible surface of the connecting element, even if they are not exactly in one plane, coplanar, or of the same area, and / or separated by shadow gaps, bevels, or radii. When the closure parts approach each other to close the closure device, the connecting element is moved from the initial position into the functional position and, in the functional position, protrudes relative to the surface. By being moved into the functional position, the connecting element can be brought into engagement with the engagement device of the first closure part in order to connect the closure parts to one another in the closed position.

[0026] In one embodiment, the surface of the second body does not contact the first body in the closed position. Because the connecting element is locked in its position when the closure device is in the closed position, the bodies of the closure parts can be kept at a distance from one another in the closed position, whereby it can be achieved that in particular the surface of the second closure part does not contact the body of the first closure part. The connection of the closure parts is thus established independently of the nature of the bodies of the closure parts, in particular a surface design of the bodies of the closure parts, for example padding on one of the bodies of the closure parts.

[0027] In one embodiment, the connecting element has a locking part arranged on the second body, which in the functional position rests against the second body. The locking part can, in particular, limit the pivoting path of the connecting element relative to the second body in the direction of the functional position by means of the contact such that the connecting element cannot be pivoted relative to the second body beyond the functional position. Furthermore, the locking part can, for example, close an opening in the surface of the second body that is exposed by the head of the connecting element when the connecting element is in the functional position.

[0028] The engagement device of the first closure part can be designed in different ways.

[0029] For example, the engagement device can be designed to establish a latching connection with the connecting element in the closed position. For this purpose, the engagement device can comprise, for example, a spring locking element, such as that described in DE 10 2010 044 198 A1. When the closure device is closed, the connecting element thus engages the engagement device in a latching manner and is preferably held positively on the engagement device in the closed position.

[0030] Such a spring locking element or an arrangement of spring locking elements can, for example, be designed as described in different embodiments in EP 2 389 084 B1, EP 2 040 572 B1 or EP 2 254 435 B1.

[0031] In one embodiment, the engagement device has an insertion opening into which the connecting element can be inserted in the functional position for closing the closure device.

[0032] In this case, it can be provided that the first magnetic device is arranged on the first body of the first closure part in the region of the insertion opening and is designed to interact with the second magnetic device on the connecting element of the second closure part when the first closure part and the second closure part approach one another to close the closure device in such a way that the connecting element is drawn into the insertion opening due to the magnetic attraction. For example, the first magnetic device can be arranged on a base of the insertion opening so that the connecting element is moved into the insertion opening by magnetic interaction with the second magnetic device on the connecting element of the second closure part, and the connecting element is thus magnetically drawn into the insertion opening.

[0033] For example, a receiving opening can adjoin the insertion opening, which extends from the insertion opening along an insertion direction (preferably different from the closing direction, for example pointing transversely or obliquely to the closing direction) and into which the connecting element can be pushed in the insertion direction after being inserted into the insertion opening in order to transfer the closure device into the closed position. The closure device is thus closed, for example, in such a way that the connecting element is first inserted into the insertion opening along the closing direction and then pushed transversely to the closing direction into the receiving opening adjoining the insertion opening. In the closed position, the connecting element is, for example, in form-fitting engagement with the receiving opening, so that the closure parts are held together.For example, the insertion direction can be directed along the axis of rotation about which the connecting element can be pivoted relative to the body of the second closure part.

[0034] The insertion direction can be linear or can also point along a curved, arcuate path of movement. In particular, the insertion direction can point around the closing direction, so that the closure parts can be connected to one another by a rotational movement around the closing direction. This can be advantageous, for example, when several, for example, three or more, connecting elements are provided.

[0035] For example, the receiving opening has at least one edge portion. In the closed position, the connecting element engages behind the at least one edge portion, creating a positive connection between the connecting element and the engagement device, and securing the closure parts to one another in a positive-locking manner.

[0036] In this text, a positive engagement or a positive connection is understood to mean that the locking parts are caught together due to the shape of the engagement device on the one hand and the connecting element on the other, and thus cannot be separated from each other, at least not without breaking the positive connection. The positive connection may be subject to play. Surfaces of engaging projections that engage with each other can also be beveled or curved, for example, spherically shaped.

[0037] For example, the receiving opening has a slotted opening through which the connecting element engages in the closed position. The slotted opening can, for example, be defined between edge sections of the receiving opening, which extend approximately parallel to one another along the insertion direction, or at an oblique angle to the insertion direction, resulting in a tapered slotted opening that tapers in the insertion direction. In the closed position, the connecting element engages behind the edge sections of the slotted opening with its head, for example an engagement projection formed on the head, so that a positive engagement exists between the connecting elements and the engagement device.

[0038] In one embodiment, the receiving opening has an engagement groove extending along the insertion direction, into which the connecting element engages in the closed position. The engagement groove can preferably be recessed with respect to a plane perpendicular to the adjustment direction. For example, the connecting element has an engagement web extending along the insertion direction, which can be inserted into the engagement groove along the insertion direction and engages in the engagement groove in the closed position. The engagement is preferably such that, due to the engagement of the engagement web in the engagement groove, the connecting element is (also) fixed to one another in a direction perpendicular to the insertion direction and the adjustment direction.

[0039] In one embodiment, the first closure part has a locking device designed to lock the connecting element to prevent movement counter to the insertion direction out of the closed position. The connecting element can be inserted into the receiving opening in the insertion direction, passing through the locking device during the insertion movement. However, when the closure device is in the closed position, the locking device prevents or at least impedes movement of the connecting element out of the receiving opening counter to the insertion direction.

[0040] For example, the locking device can have a locking element that is adjustable relative to the first body, past which the connecting element can be moved in the insertion direction to transfer it into the closed position, but which blocks movement of the connecting element counter to the insertion direction from the closed position. When moving in the insertion direction, the connecting element pushes the locking element aside, for example, so that the locking element can be passed. Once the connecting element has passed the locking element, the locking element snaps back into a locked position, so that moving the connecting element back out of the receiving opening is blocked or made more difficult.

[0041] The locking element is advantageously elastically movable relative to the body. In particular, the locking element can be spring-loaded relative to the body via a spring element. In another embodiment, the locking element can also be magnetically preloaded relative to the body and elastically adjustable such that, after being deflected from a home position, the locking element returns to the home position due to the preload.

[0042] The locking element can, for example, protrude into the receiving opening in such a way that the connecting element comes into contact with the locking element when moved back against the insertion direction and thus the connecting element is locked in the receiving opening.

[0043] To make opening more difficult, the locking element can, for example, be bevelled on a stop surface facing the connecting element in the closed position along the insertion direction, so that the connecting element can run onto the stop surface counter to the insertion direction and the locking direction can thus be opened when a limit force (determined by the shape of the stop surface and the connecting element and also by a spring preload) is overcome.

[0044] In contrast, to block the opening, a stop surface of the locking element facing the connecting element in the closed position along the insertion direction can be positioned, for example, perpendicular to the insertion direction, so that the connecting element cannot run onto the stop surface and the locking device can only be opened by actuating the locking device to unlock.

[0045] For example, due to the engagement of the connecting element in the engagement device, the connecting element can be fixed relative to the first closure part in the closed position along a plane perpendicular to the rotation axis. Due to the engagement of the connecting element with the engagement device, the connecting element, viewed along the plane perpendicular to the rotation axis, is positively fixed relative to the first closure part and thus captured, wherein the connecting element is preferably held on the first closure part in a rotationally and positionally fixed manner.

[0046] In one embodiment, the second closure part has an elastically deformable prestressing element which is designed to prestress the connecting element relative to the second body, at least in the functional position. The prestressing element can be formed, for example, by an elastic spring or by a rubber element, for example an O-ring, which extends around an adjusting body of the connecting element. When transferred into the functional position, the prestressing element is elastically tensioned, so that in the functional position an elastic prestress is exerted on the connecting element relative to the body of the second closure part. In one embodiment, the connecting element is held in the initial position relative to the second body in an open position of the closure device.For example, the connecting element can be spring-mechanically or magnetically pre-tensioned relative to the body of the second closure part in the direction of the starting position.

[0047] In one embodiment, the second closure part has a third magnetic device arranged on the second body of the second closure part, which magnetically interacts with the second magnetic device to hold the connecting element in the initial position. The third magnetic device interacts with the second magnetic device in a magnetically attractive manner, so that when the closure device is open, the connecting element is held in the initial position on the body of the second closure part.If the closure parts are brought closer together, the magnetic attraction between the first magnetic device of the first closure part and the second magnetic device on the connecting element of the second closure part superimposes the magnetic attraction between the second magnetic device and the third magnetic device and exceeds this as soon as the closure parts have been brought sufficiently close to one another, so that the connecting element is transferred from the starting position into the functional position due to the magnetic attraction between the first magnetic device and the second magnetic device.

[0048] In one embodiment, the first closure part and the second closure part are fixed relative to one another in the closed position, particularly when viewed along the closing direction and along a plane perpendicular to the closing direction. Thus, in the closed position, the first closure part and the second closure part cannot be moved relative to one another, in particular not even rotationally.

[0049] The positionally fixed fixing, in particular in a plane perpendicular to the closing direction, in particular rotationally around the closing direction, can be achieved, for example, by a suitable engagement structure on the first closure part and the second closure part.

[0050] In one embodiment, the second closure part has at least two connecting elements, each of which is pivotable relative to the second body between an initial position and a functional position and, in the functional position, protrudes relative to the second body such that the connecting elements can be brought into engagement with the engagement device of the first closure part. In the closed position, the connecting elements each engage with the engagement device to hold the first closure part and the second closure part against one another. The connecting elements each have an associated second magnetic device for magnetically interacting with the first magnetic device of the first closure part.

[0051] For example, the engagement device on the first closure part can have two spring locking elements, each associated with one of the connecting elements. In another embodiment, two insertion openings and two adjoining receiving openings can be formed on the engagement device, with one insertion opening and one receiving opening each associated with one of the connecting elements.

[0052] Because the connection between the closure parts in the closed position is established via two (or more) connecting elements and their engagement with the engagement device of the first closure part, the closure parts are fixed in a positionally fixed manner, in particular also rotationally fixed, to one another in the closed position and thus establish a positionally fixed connection between assemblies that are assigned to the closure parts.

[0053] In one embodiment, the connecting elements are arranged next to one another, for example, along a transverse direction perpendicular to the closing direction and the rotational axis. In the closed position, the connecting elements are brought closer to the body of the first closure part, for example, from opposite sides.

[0054] In one embodiment, the connecting elements can be pivoted about a common axis of rotation relative to the second body.

[0055] In another embodiment, the connecting elements are pivotable relative to the second body about two parallel, spaced-apart rotational axes. In this embodiment, each connecting element is thus assigned an individual rotational axis, with the rotational axes extending parallel to one another.

[0056] In one embodiment, the connecting elements can each be pivoted relative to the second body by an angle between 20° and 150°, preferably between 30° and 100°, for transfer from the starting position to the functional position. In the starting position, the head of each locking element lies, for example, in an associated opening in a surface of the second closure part and thus does not protrude, or only slightly protrudes, from the body of the second closure part. By pivoting about the respectively associated axis of rotation, the connecting elements can be adjusted out of the body and, in the functional position, protrude outwards relative to the body, wherein the pivoting movement occurs through such an angle that the connecting elements can each be brought into engagement with the engagement device on the first body of the first closure part.

[0057] In one embodiment, the connecting elements can be pivoted relative to the second body in opposite directions about a common axis of rotation or about an associated, individual axis of rotation for transfer from the initial position to the functional position. The connecting elements are thus pivoted in opposite directions relative to each other relative to the body of the second closure part for transfer into the functional position.

[0058] In another embodiment, the connecting elements can also be pivotable in the same direction.

[0059] If more than two connecting elements are provided, the axes of rotation can all be in the same plane, but different from each other, for example.

[0060] In one embodiment, the first closure part has a first electrical contact assembly, and the second closure part has a second electrical contact assembly. When the closure device is closed, the contact assemblies, each of which may, for example, have one or more electrical contacts, come into electrical contact with one another, thus establishing an electrical connection.

[0061] The first electrical contact assembly can be formed, for example, by a first electrical connector part, and the second electrical contact assembly by a second electrical connector part. When the closure device is closed, the connector parts engage with one another in a plug-in manner. The first electrical connector part and the second electrical connector part are connected to one another in a plug-in manner in the closed position. A plug-in direction, along which the plug-in connection is to be established, preferably corresponds to the insertion direction. The connector parts can be used, for example, to establish a data connection or to establish an electrical supply connection between assemblies assigned to the closure parts.The connector parts can be formed, for example, by USB ports, for example USB-C ports, or other ports for electrical or electronic devices, for example for telecommunications applications.

[0062] In one embodiment, the second electrical contact assembly, for example, the second connector part, is arranged on the connecting element of the second closure part. For example, the first connector part can be arranged in the region of a receiving opening of the engagement device of the first closure part. If the connecting element is brought into engagement with the engagement device upon closing the closure device, the connector parts are connected to one another in a plug-in manner, so that in addition to the mechanical fastening of the closure parts to one another, an electrical connection is also established.

[0063] The closure device is designed to be magnetic. The first magnetic device and the second magnetic device can, for example, each be formed by a permanent magnet that faces each other with opposite poles and thus magnetically attracts each other. In another embodiment, the first magnetic device and the second magnetic device can be formed, on the one hand, by a permanent magnet and, on the other hand, by a passive magnetic armature, for example, made of a ferromagnetic material.

[0064] If the second magnetic device is formed by a permanent magnet, the third magnetic device can be formed, for example, by a passive magnetic armature. In another embodiment, the third magnetic device is formed by a permanent magnet that is magnetically attractive to the second magnetic device.

[0065] One or more of the magnetic devices can also be formed by electromagnets, for example.

[0137] In an embodiment illustrated in Fig. 1A, 1B to Fig. 5A-5E, a closure device 1 comprises a first closure part 2 and a second closure part 3 to be connected to the first closure part 2 along a closing direction X. The closure parts 2, 3 are separated from one another in an open position, illustrated in Fig. 2A to 2E. In a closed position, illustrated in Fig. 5A to 5E, the closure parts 2, 3 are fastened to one another, so that assemblies assigned to the closure parts 2, 3 are connected to one another via the closure device 1.

[0138] The closure part 2 has a body 20 on which an engagement device 21 is formed. The engagement device 21 forms, as can be seen, for example, from the exploded view according to Fig. 1B, insertion openings 210A, 210B, each of which is adjoined along an insertion direction Y by an associated receiving opening 211A, 211B.

[0139] Magnetic devices 22A, 22B are arranged in the region of the insertion openings 210A, 210B on the body 20. In the illustrated embodiment, the magnetic devices 22A, 22B are designed as permanent magnets and are accommodated in associated mounting openings on the body 20, as can be seen from the exploded view according to Fig. 1A.

[0140] The closure part 3 has connecting elements 34A, 34B, which are connected via an axle element

[0141] 348 are pivotally mounted on a bearing section 303 and above it on a body 30 of the closure part 3 about a common axis of rotation D. The axis of rotation D extends perpendicular to the closing direction X and points along the insertion direction Y.

[0142] Each connecting element 34A, 34B has a magnetic device 32A, 32B in the form of a permanent magnet, which interacts in a magnetically attractive manner with a respective associated magnetic device 22A, 22B on the body 20 of the closure part 2. As can be seen from the sectional view according to Fig. 2D in conjunction with Fig. 1A, the magnetic devices 32A, 32B are arranged in the region of a head 343 of the respective associated connecting element 34A, 34B.

[0143] Each connecting element 34A, 34B has an adjusting body 340 that extends arcuately (at an approximately constant radius) around the rotational axis D and on which the head 343 is formed. Each head 343 forms an engagement web 347 for engaging in an engagement groove 213 in an associated receiving opening 211A, 211B of the engagement device 21 of the closure part 2. The adjusting body 340 is mounted on the axle element 348 via a lever arm 345 and is thus pivotable about the rotational axis D relative to the body 30 of the closure part 3.

[0144] A closing part 346 is formed on the adjusting body 340 of the respective connecting element 34A, 34B, which protrudes radially to the adjusting body 340 and is flat, so that in a functional position of the respective connecting element 34A, 34B, an associated opening 302A, 302B formed on the surface 300 of the body 30 is closed by the closing part 346, as can be seen from Figs. 5A and 5B.

[0145] The locking part 346 serves as a stop to limit the pivoting path of the respective connecting element 34A, 34B relative to the body 30. In the functional position, the locking part 346 rests against the body 30, so that the respective connecting element 34A, 34B cannot be pivoted relative to the body 30 beyond the functional position.

[0146] Magnetic devices 36A, 36B in the form of permanent magnets are arranged on the body 30 of the closure part 3, which interact in a magnetically attractive manner with the magnetic devices 32A, 32B of the connecting elements 34A, 34B, so that, when the closure device 1 is open, the connecting elements 34A, 34B are held in their assumed position corresponding to an initial position. In the open position of the closure device 1, shown in Figs. 2A to 2E, the closure parts 2, 3 are separated from one another. The connecting elements 34A, 34B are in the initial position shown in Figs. 2A to 2E, in which the heads 343 of the connecting elements 34A, 34B are flush with the surface 300 of the body 30 and thus do not protrude outwards. In the initial position, the connecting elements 34A, 34B are thus received inside the guide parts 31A, 31B and countersunk relative to the body 30 of the closure part 3.

[0147] In the initial position when the closure device 1 is open, the magnetic devices 32A, 32B of the connecting parts 34A, 34B interact with the stationary magnetic devices 36A, 36B on the body 30 of the closure part 3 and thereby magnetically hold the connecting elements 34A, 34B in the initial position.

[0148] Because the connecting elements 34A, 34B do not protrude outwards from the body 30 in the initial position, the connecting elements 34A, 34B are not obstructive when the closure device 1 is open and do not disturb an aesthetic impression, for example in the interior of a vehicle (for example when the closure part 3 is fixed to an associated assembly, for example to a vehicle seat, in order to enable an assembly associated with the closure part 2 to be fastened to the vehicle assembly associated with the closure part 3 by connecting it to the closure part 2).

[0149] If the closure parts 2, 3 are brought closer to one another (for example approximately along the closing direction X), as can be seen from Fig. 3A to 3E, the closure parts 2, 3 are brought into a position relative to one another due to the magnetic attraction forces between the magnetic devices 22A, 22B on the closure part 2 and the magnetic devices 32A, 32B on the closure part 3, in which the connecting elements 34A, 34B assume a position opposite the insertion openings 210A, 210B, as can be seen from the sectional view according to Fig. 3D.

[0150] If the closure parts 2, 3 are brought close to one another to such an extent that the magnetic attraction forces between the magnetic devices 22A, 22B on the closure part 2 and the magnetic devices 32A, 32B on the closure part 3 exceed the magnetic holding forces between the magnetic devices 32A, 32B, 36A, 36B on the closure part 3, the connecting elements 34A, 34B are moved from the starting position according to Fig. 3A to 3E in the direction of the functional position relative to the body 30 of the closure part 3, as can be seen from Fig. 4A to 4E. The connecting elements 34A, 34B are thus pivoted about the common axis of rotation D relative to the body 30 of the closure part 3 and thereby moved with the adjusting body 340 through the associated opening 302A, 302B in the surface 300 of the body 30, so that the connecting elements 34A, 34B protrude with their heads 343 relative to the surface 300 of the body 30.

[0151] In the illustrated embodiment, the connecting elements 34A, 34B are pivoted by an angle between 30° and 60°, for example approximately 45°, relative to the body 30 of the closure part 3 for transfer from the initial position (Figs. 3A to 3E) to the functional position (Figs. 4A to 4E). The pivoting takes place about a common axis of rotation D defined by the axle element 34B, wherein the connecting elements 34A, 34B are adjusted in mutually opposite adjustment directions V relative to the body 30, as can be seen in particular from Fig. 4D in conjunction with Fig. 3D.

[0152] Due to the magnetic attraction between the magnetic devices 22A, 22B of the closure part 2 and the magnetic devices 32A, 32B of the connecting elements 34A, 34B, the connecting elements 34A, 34B are drawn into the insertion openings 210A, 210B of the engagement device 21 of the closure part 2, as can be seen from Fig. 4A to 4E. In the position according to Fig. 4A to 4E, the connecting elements 34A, 34B are in contact with a respective base of the associated insertion opening 210A, 210B and are located opposite the magnetic devices 22A, 22B on the body 20 of the closure part 2, as can be seen from Fig. 4D.

[0153] To completely close the closure device 1, the closure parts 2, 3 are now displaced relative to one another along the insertion direction Y, which extends transversely to the closing direction X and points along the axis of rotation D, so that the connecting elements 34A, 34B slide into the receiving openings 211A, 211B along the insertion direction Y, as can be seen from Fig. 5A to 5E. The connecting elements 34A, 34B thus engage with the receiving openings 211A, 211B such that the connecting elements 34A, 34B engage behind edge sections 212 of the receiving openings 211A, 211B with their heads 343.

[0154] On the head 343 of each connecting element 34A, 34B, an engagement web 347 is formed, which protrudes from the head 343 opposite to the respectively assigned adjustment direction V (rearwardly, so to speak, with respect to the transfer direction from the initial position to the functional position). When the connecting elements 34A, 34B are inserted into the receiving openings 211A, 211B, the respective engagement web 347 is inserted into an associated, complementary engagement groove 213 on an edge portion 212, as can be seen in particular from Fig. 5B in conjunction with Fig. 5D. In the closed position according to Fig. 5A to 5E, the head 343 of each connecting element 34A, 34B is thus engaged with the associated receiving opening 211A, 211B in such a way that the head 343 is completely caught on the engagement device 21 in a plane perpendicular to the rotation axis D and is thus locked in the plane perpendicular to the rotation axis D relative to the engagement device 21.

[0155] In the closed position, each connecting element 34A, 34B is locked on the engagement device 21, in particular counter to the associated adjustment direction V pointing around the rotation axis D, so that the respective connecting element 34A, 34B cannot be removed from the body 20 of the closure part 2 counter to the adjustment direction V, at least not without the connecting element 34A, 34B being pushed out of engagement from the engagement device 21 counter to the insertion direction Y and the engagement is thus canceled.

[0156] Because the connecting elements 34A, 34B are jointly fixed to the engagement device 21 and thus to the body 20 of the closure part 2, the closure parts 2, 3 are fixed in position relative to one another in the plane perpendicular to the axis of rotation D.

[0157] In the closed position, the openings 302A, 302B in the surface 300 of the body 30 of the closure part 3 are closed by the closing parts 346 of the connecting elements 34A, 34B, as can be seen from Figs. 5A to 5E. The closing parts 346 are each in contact with the body 30 from the inside in such a way that the connecting elements 34A, 34B cannot be adjusted further in the respectively assigned adjustment direction V.

[0158] In the illustrated embodiment, the connecting elements 34A, 34B are inserted into the receiving openings 211A, 211B manually by a user, whereby the insertion can be assisted, for example, by gravity.

[0159] When inserted into the receiving openings 211A, 211B, the magnetic devices 22A, 22B on the closure part 2 and the magnetic devices 32A, 32B on the connecting elements 34A, 34B on the closure part 3 are moved away from one another tangentially along the insertion direction Y, so that insertion takes place against the magnetic attraction force of the magnetic devices 22A, 22B, 32A, 32B. In the exemplary embodiment shown in Fig. 1A, 1B to Fig. 5A to 5E, for example, a locking device can be arranged on the body 20 of the closure part 2, which locking device has a locking element that is adjustable on the body 20 transversely to the insertion direction Y and is spring-biased relative to the body 20, for example via a spring element.Such a locking element can, for example, engage with a locking lug in the area of ​​one or both of the receiving openings 211A, 211B, so that the respective connecting element 34A, 34B slides with its head 343 onto the locking lug when inserted into the receiving opening 211A, 211B, pushes it aside, and thus passes the locking element. In the closed position, the locking device 1 is then locked in that the respective connecting element 34A, 34B is blocked by the locking device in the receiving opening 211A, 211B and thus cannot slide out of the associated receiving opening 211A, 211B opposite to the insertion direction Y.If the locking device 1 is to be opened again, a user can, for example, manually act on the locking device and adjust it so that the connecting elements 34A, 34B can be pushed out of the receiving openings 211 A, 211 B along the insertion direction Y and the locking device 1 can thus be opened.

[0160] In the closed position according to Figs. 5A to 5E, the connecting elements 34A, 34B are fixed in their position relative to the body 30 of the closure part 3 because the connecting elements 34A, 34B jointly engage the engagement device 21 and are fixed relative to the engagement device 21. The connecting elements 34A, 34B are thereby completely fixed in their position relative to the body 30 and by the locking parts 346 in contact with the body 30. This means that the connection between the closure parts 2, 3 is independent of whether the bodies 20, 30 of the closure parts 2, 3 touch each other in the closed position. Rather, the connection is established solely via the connecting elements 34A, 34B and their engagement in the engagement device 21, wherein the surface 300 of the body 30 of the closure part 3 can be spaced from the body 20 of the closure part 2, as can be seen, for example, from Figs. 5A to 5E.

[0161] Because the bodies 20, 30 of the closure parts 2, 3 do not engage one another in the closed position, the bodies 20, 30 of the closure parts 2, 3 can have any desired shape on their mutually facing sides. In particular, the surface 300 of the body 30 of the closure part 3 can be curved or corrugated, rather than a flat shape. Because the connection of the closure parts 2, 3 in the closed position is independent of the contact of the bodies 20, 30, the shape of the bodies 20, 30 on their mutually facing sides or, for example, padding on the surface 300 does not impair the connection of the closure parts 2, 3.

[0162] This also enables, in particular, integration of one or both closure parts 2, 3 into respective associated assemblies, for example into a vehicle assembly, for example into a vehicle seat.

[0163] In another embodiment shown in Figs. 6A, 6B to 10A-10E, the connecting elements 34A, 34B of the closure part 3 are each pivotably mounted about an individual axis of rotation D on an associated axle element 348A, 348B and above that on an associated bearing section 303 of the body 30 of the closure part 3.

[0164] The connecting elements 34A, 34B are in turn to be pivoted in opposite directions to each other in order to pivot the connecting elements 34A, 34B from the starting position (Fig. 7A to 7E) into the functional position (Fig. 9A-9E).

[0165] While in the embodiment according to Fig. 1A, 1B to 5A-5E the connecting elements 34A, 34B are to be pivoted by an angle between 30° and 60°, for example approximately 45°, relative to the body 30 of the closure part 3 in order to pivot the connecting elements 34A, 34B between the initial position and the functional position, in the embodiment according to Fig. 6A, 6B to 10A-10E the connecting elements 34A, 34B are to be pivoted by an angle of approximately 90° relative to the body 30 of the closure part 3.

[0166] In the closed position, shown in Fig. 10A to 10E, the heads 343 of the connecting elements 34A, 34B thus point towards each other, the body 20 of the closure part 2 assuming an intermediate position between the heads 343 of the connecting elements 34A, 34B.

[0167] Otherwise, the embodiment according to Figs. 6A, 6B to 10A-10E is functionally identical to the embodiment according to Figs. 1A, 1B to 5A-5E, so reference should also be made to the preceding explanations. Figs. 11A-11C to 15A-15G show a further embodiment of a closure device 1, which is functionally largely identical to the closure device 1 of the embodiment according to Figs. 1A, 1B and 5A-5E.

[0168] Thus, in the embodiment according to Fig. 11A-11C to 15A-15G, an engagement device 21 is formed on a body 20 of a first closure part 2, which engagement device forms insertion openings 210A, 210B, to which an associated receiving opening 211A, 211B adjoins in each case along an insertion direction Y. Magnetic devices 22A, 22B are arranged in the region of the insertion openings 210A, 210B on the body 20 and, in the illustrated embodiment, are designed as permanent magnets and received in associated mounting openings on the body 20.

[0169] A second closure part 3 has connecting elements 34A, 34B, which are pivotally mounted about a common axis of rotation D via an axle element 348 on a bearing section 303 and, above this, on a body 30 of the closure part 3. The axis of rotation D extends perpendicular to a closing direction X and points along the insertion direction Y. Each connecting element 34A, 34B has a magnetic device 32A, 32B in the form of a permanent magnet, which interacts in a magnetically attractive manner with a respectively associated magnetic device 22A, 22B on the body 20 of the closure part 2.

[0170] In contrast to the embodiment according to Figs. 1A, 1B to 5A-5D, in the embodiment according to Figs. 11A-11C to 15A-15G, the bearing section 303 is formed on a bearing element 304 that is connected to the body 30 and thus fixed to the body. Magnetic devices 36A, 36B are arranged on receiving sections 305 of the bearing element 304, which magnetic devices are formed, for example, as passive magnetic ferromagnetic armatures.

[0171] When the closure parts 2, 3 are separated (shown in Fig. 12A-12D), the closure parts 2, 3 are separate from one another. In the open position of the closure device 1, the connecting elements 34A, 34B each assume an initial position on the body 30, in which the connecting elements 34A, 34B with heads 343 are inserted into openings 302A, 302B of the body 30 of the closure part 3 such that the heads 343 are at least approximately flush with a surface 300 of the body 30, as can be seen, for example, in Fig. 12D. The connecting elements 34A, 34B are held in the starting position by the magnetic devices 32A, 32B of the connecting elements 34A, 34B interacting in a magnetically attractive manner with the magnetic devices 36A, 36B on the receiving sections 305 of the bearing element 304.

[0172] To close the closure device 1, the closure parts 2, 3 are (approximately) placed against one another along the closing direction X (shown in Fig. 13A-13G), so that the connecting elements 34A, 34B with the heads 34B are brought closer to the insertion openings 210A, 210B on the body 20 of the closure part 2. If the magnetic attraction force between the magnetic devices 32A, 32B of the connecting elements 34A, 34B of the closure part 3 and the magnetic devices 22A, 22B in the region of the insertion openings 21OA, 21OB on the body 20 of the closure part 2 exceeds the holding force on the connecting elements 34A, 34B caused by the magnetic interaction between the magnetic devices 32A, 32B and the magnetic devices 36A, 36B, the connecting elements 34A, 34B are pivoted about the pivot axis D, as can be seen from Fig. 14A-14G.

[0173] To completely close the closure device 1, the closure parts 2, 3 are now displaced relative to one another along the insertion direction Y, which extends transversely to the closing direction X and points along the axis of rotation D, so that the connecting elements 34A, 34B with the heads 343 slide along the insertion direction Y into the receiving openings 211A, 211B, as can be seen from Fig. 15A-15G. The connecting elements 34A, 34B thus engage with the receiving openings 211A, 211B in such a way that the connecting elements 34A, 34B engage behind edge sections 212 of the receiving openings 211A, 211B with their heads 343 and engagement webs 347 on the heads 343 engage in engagement grooves 213 in the region of the receiving openings 211A, 211B.

[0174] 1A, 1B to 5A-5E, in the embodiment according to Fig. 11A-11C to 15A-15G, further magnetic devices 22C, 22D are arranged in the region of the receiving openings 211A, 211B, which, when the heads 343 of the connecting elements 34A, 34B are inserted, interact in a magnetically attractive manner with the magnetic devices 32A, 32B on the connecting elements 34A, 34B and thus magnetically support the insertion of the connecting elements 34A, 34B into the receiving openings 211A, 211B. In addition, in the region of the receiving opening 211 A on the body 20 of the closure part 2, a locking device 23 is arranged, which is formed by a locking element 230 which is mounted on a bearing device 214 on the body 20 so as to be tiltable about an axis element 231.

[0175] The locking element 230 has tensioning elements 233 in the form of elastically deformable sections, via which the locking element 230 is elastically pretensioned relative to the body 20 in the direction of a locking position. In the locking position, the locking element 230 engages with a locking head 232 in the region of the receiving opening 211A, in that the locking head 232 comes to rest in the region of the engagement groove 213 on the edge section 212 of the receiving opening 211A, as can be seen, for example, in Fig. 13E in conjunction with Figs. 13F and 13G.

[0176] When the connecting elements 34A, 34B are inserted into the receiving openings 211A, 211B, the head 343 of the connecting element 34A slides onto the locking head 232 of the locking element 230 and deflects the locking element 230 such that the head 343 of the connecting element 34A can pass the locking head 232 and slide with the engagement web 347 into the engagement groove 213 within the receiving opening 211A. The connecting elements 34A, 34B thus reach the closed position according to Fig. 15A-15G.

[0177] The deflection of the locking element 230 when the connecting element 34A slides into the associated receiving opening 211A occurs counter to the elastic preload of the clamping elements 233. After the head 343 of the connecting element 34A has passed the locking head 232, the locking element 230 returns to the locking position due to the spring-elastic preload, in which the locking head 232 blocks the exit of the engagement groove 213 and thus prevents the connecting element 34A from sliding out of the receiving opening 211A.

[0178] An actuating portion 234 in the form of a lever portion is formed on the locking element 230, which a user can act on, for example, with a finger, in order to move the locking element 230 out of the locking position and thus open the closure device 1 from the closed position shown in Fig. 15A-15G.
