Abstract
Description
The invention relates to a locking mechanism which is provided and designed to interact with a locking element.From the prior art, locking mechanisms are known, in which it is assumed purely on the assumption that a secure locking between different components has been achieved.WO 2020 / 224 793 A1 discloses a locking mechanism which is provided and designed to interact with locking elements in order to bring a locking between the locking mechanism and the locking elements closer.DE 198 08 374 A1 relates to a device for locking a cover in the manner of a body hood of a motor vehicle.DE 10 2007 031 189 B4 relates to a set of a mating plug connector and a plug connector with electrical contacts for insertion into mating contact of the mating plug connector.The object of the present invention is to achieve a connection which is as secure as possible by means of a connection mechanism between the component and the element, which connection is realized in a particularly simple manner in terms of design. The present locking mechanism is based on the fail-safe principle.The object is achieved in the present case by a locking mechanism having the features of patent claim 1.A core idea of the present invention is to provide a locking mechanism which is provided and designed to interact with two locking elements in order to produce or release a locking.According to the invention, it should be provided that a locking mechanism is provided which is provided and configured to interact with at least one locking element in order to establish a locking between the locking mechanism and the locking element, wherein the locking mechanism comprises a first locking pawl and a second locking pawl which are rotatable independently of one another about a first axis of rotation, wherein the first locking pawl is provided and configured to interact with a first locking element, and wherein the second locking pawl is provided and configured to interact with a second locking element, wherein a secured locking is present when the first locking element is locked with the first locking pawl and the second locking element is locked with the second locking pawl.A locking is to be understood here in such a way that a movement of the component to the element in at least one spatial direction can be prevented, in particular at least in the height direction.The locking by the locking mechanism is based on the fail-safe principle.In contrast, there is an unlocked lock when at most one locking element is locked with the corresponding locking pawl. That is to say that either none of the locking elements is connected to the corresponding locking pawl or only one of the locking elements is connected to the corresponding locking pawl.It is provided that the locking mechanism comprises a first pawl and a second pawl which are synchronously rotatable about a second axis of rotation, wherein the first pawl is provided and configured to be able to interact with the first locking pawl, and wherein the second pawl is provided and configured to be able to interact with the second locking pawl such that the locking pawls are held in a locked or unlocked position.It is contemplated that a first comfort pawl and a second comfort pawl are provided that are provided and configured to accommodate tolerances between the respective pawls and locking pawls so that the locking pawls can be fully rotated to the locked position.A basic idea is to be able to provide a component which can be detachably connected to an element. This releasable connection can be realized by means of the locking mechanism in cooperation with one, two or more locking elements.It is particularly preferably provided that the locking mechanism can interact with at least two locking elements. This has the advantage that, on the one hand, a movement in the height direction and rotational movements about the height direction in a plane perpendicular to the height direction can be prevented.Furthermore, it is preferably provided that the locking mechanism is designed and provided for the purpose that, in the case of a locking with only at most one of the two locking elements, it can be signaled that no secured locking is present.The locking mechanism can be described structurally as follows.According to the invention, the locking mechanism comprises a first locking pawl and a second locking pawl. The locking pawls are connected to a locking axis extending in a direction perpendicular to the height direction, for example, a width direction. Furthermore, the locking pawls are independently rotatable about the first axis of rotation which is formed by the locking axis. The connection of the locking pawls to the locking axis is preferably such that the locking pawls are rotatable with respect to the locking axis.Further preferably, the locking latches can be spaced apart from one another in the width direction, preferably at a first distance from one another. By the spacing of the locking pawls from one another and the rotatable connection to the locking axis, the locking pawls are arranged independently of one another rotatably about the width direction. This means that a locking of the first locking pawl and a locking of the second locking pawl, i.e. a connection to the first locking element or the second locking element, are independent of one another.The locking elements are preferably arranged in a manner analogous to the locking latches with respect to one another.According to a particularly preferred embodiment, a first pawl and a second pawl are provided, which are provided and configured such that the first pawl can interact with the first locking pawl and the second pawl can interact with the second locking pawl in order to be able to achieve a secured locking and a release of the locking. Preferably, the pawls are spaced apart from each other, preferably in the width direction. Preferably, the locking pawls are arranged in a manner analogous to the locking pawls with respect to one another.The ratchet pawls are preferably connected to a synchronizing axis in a rotationally fixed manner, as a result of which a synchronized movement of the ratchet pawls can be achieved. This means that when the locking mechanism is actuated, locking of the two locking latches is always sought. Preferably, the synchronous axis is arranged parallel to the locking axis and is spaced apart therefrom.The synchronizing axis, by which the second axis of rotation is realized, and the locking axis, by which the first axis of rotation is realized, can be formed by shafts.According to a preferred embodiment, it can be provided that the first axis of rotation and the second axis of rotation are spaced apart and arranged parallel to one another.By spacing the axes of rotation from one another, good rotation of the individual pawls with respect to one another and good interaction between pawls and locking pawls can be achieved.Particularly preferably, the synchronous axis and the locking axis are mounted in a fixed position with these holding elements apart from rotation between a first holding element and a second holding element.The locking pawls and the ratchet pawls extend in the radial direction about the respective axis or axis of rotation.According to one embodiment, it can particularly preferably be provided that each of the locking pawls can be brought from the unlocked position into the position of the locking pawl locked with the corresponding locking element by a rotation in a first rotational direction about the first rotational axis, wherein the rotation of the locking pawl can be brought into contact and a movement of the locking pawl and the locking element towards one another can be brought about.This means that in a first rotational position of the respective locking pawl the non-locked position is present and in a second rotational position the locked position with respect to the locking pawls is present. If both locking latches are in the locked position, the secured locking is present. If at most one locking pawl is in the locked position, the non-secured locking is present.Because the locking pawls can be moved independently of one another, the locking by the locking pawls is also independent of one another.Because the locking pawls are preferably provided and configured to hold the locking pawls in a locked or unlocked position, it can be provided according to a preferred embodiment that in the unlocked position the locking pawls are connected to a first region of the corresponding locking pawl and in the locked position the locking pawls are connected to a second region of the corresponding locking pawl, wherein the respective locking pawl can be displaced from the first region into the second region by the rotation in the first rotational direction.Preferably, the first region and the second region of a locking pawl differ from one another. The pawl can be displaced from the first region into the second region and vice versa by a rotational movement about the second axis of rotation, depending on the rotational position of the respectively associated locking pawl.In order to return the locking mechanism with the lockable locking pawls from the locked position into the unlocked position, it can be provided according to a preferred embodiment that, in order to return the locking pawl from the locked position into the unlocked position, a return element, preferably a Bowden cable element, is provided, which is connected to the second axis of rotation in such a way that, by actuation of the return element or the Bowden cable element, a rotation of the pawls in a second direction of rotation, which is opposite to the first direction of rotation, can be triggered.For improved locking and / or resetting of the locking mechanism or the locking pawls, it can preferably be provided according to a further embodiment that the first axis of rotation is acted upon by a first spring force and the locking pawls are each acted upon by a spring force, wherein the first spring force is acted upon by a first torsion spring and each locking pawl is acted upon by a tension spring.It can further be provided that the synchronizing axis is acted upon by the first spring force. The first spring force can be provided, for example, by the first torsion spring. For this purpose, the first torsion spring is connected on the one hand to the synchronous axis and on the other hand to one of the retaining elements. In this case, the first torsion spring is preferably arranged in such a way that the first torsion spring is prestressed in the unlocked position of the respective pawl or locking pawl, that is to say that, when during a rotational movement in the first rotational direction of the locking pawl, the pawl rotates from the first region into the second region on account of the first spring force.It can further preferably be provided that the locking pawls are each acted upon by a spring force. Particularly preferably, each locking pawl is connected to a tension spring, wherein the tension spring is connected on the one hand to the corresponding locking pawl and on the other hand to one of the retaining elements or to a further element fixed in place. It is preferably provided that the tension spring is designed such that the tension spring is tensioned in the locked position or has a higher spring tension than in the unlocked position. That is to say that when the pawl rotates from the second region into the first region, the respective locking pawl is rotated in the second rotational direction due to the tension spring, so that the locking pawl can be displaced into the first rotational position from the second rotational position.By acting upon the synchronizing axle or upon the locking latches with a spring force, rotary movements of the axles can be achieved depending on the position of the elements relative to one another. Likewise, resettings of the respective elements can be achieved, depending on which position is assumed.Particularly preferably, the spring forces of the synchronizing axis and of the locking elements are applied in opposite directions to one another, so that rotations in different directions to one another are possible, which can promote the locking or the release of the locking.In the following, a possible movement sequence of a locking is described, that is to say that the locking latches are to be brought into contact with the locking elements.In a basic state of the locking mechanism, the locking pawls and the locking pawls are configured to contact one another. Preferably, the pawls contact a first portion of the locking pawls.If the locking mechanism is brought into contact with the locking elements by the locking elements and the locking pawls being moved towards one another and brought into contact, this results in a rotational movement of the locking pawls in a first rotational direction. The pawls and the locking pawls continue to contact each other in the first region.The locking pawls are now moved further in the first direction of rotation the closer the locking mechanism and the locking elements are moved towards one another.After a certain rotational distance of the locking pawls, the contacting of the locking pawls and the ratchets is released, that is to say that the ratchets and locking pawls no longer contact one another. By the application of force to the ratchets, a rotational movement in the first rotational direction of the ratchets is now achieved. The pawls rotate until they contact the locking pawls in a second region. The lock mechanism is connected to the lock member and the lock pawl, and thus locking has been established.It should be noted here that a rotation of a locking pawl is only caused when the locking pawl comes into contact with a locking element. If this is not the case, the locking pawl is not rotated.When the locking is unlocked or released, the last-described state of the locking is the initial state for unlocking that is now present.In a first step, a rotational movement of the ratchet pawls is now brought about in a second rotational direction which is opposite to the first rotational direction. Preferably, the synchronous axle or the ratchets can be connected to a Bowden cable element, so that a rotation in the second direction can be triggered upon actuation of the Bowden cable element.By this rotation of the synchronizing axis with the ratchets in the second rotational direction, the ratchets are moved relative to the locking pawls. In this case, the pawl and the locking pawl contact each other in the second region until a specific rotational distance has been covered and the connection between the pawl and the locking pawl is released.Because the locking pawls are likewise acted upon by a spring force, the locking pawls are reset, i.e. a rotational movement in the second rotational direction until the pawl and the locking pawl contact one another again in the first region. The rotation of the locking pawl releases the locking pawl from the locking element.Because the synchronizing axis is connected to the Bowden cable element, a first end of the Bowden cable element, which is connected to the synchronizing axis, moves in accordance with the movement of the synchronizing axis with or indirectly causes a movement of the synchronizing axis.This means specifically that the first end of the Bowden cable element is moved along by the movement of the synchronizing axis of the locking mechanism, i.e. when both locking latches are locked. It should be noted that only a rotation of the synchronizing axis occurs when both ratchet pawls experience a rotation, which only experience a rotation when both locking pawls experience a rotation due to the contacting with the respective locking element.During unlocking, the Bowden cable element is actuated, i.e. the first end itself is actuated, whereby the synchronizing axis and corresponding the ratchet pawls are rotated.The element may be, for example, a box element that may be removed from the vehicle due to space problems, or introduced due to a desired storage or storage space.The locking or unlocking can also be described in terms of the method.In the case of a locking, the method steps would be provided as follows:providing the locking mechanism and the locking elements;contacting the locking mechanism and the locking elements by moving them towards each other, whereby the locking pawls are rotated and the connection between the locking pawls and the locking pawls in the first region is released;Upon releasing the connection of the first region, the synchronizing axis is rotated with the ratchet pawls until the ratchet pawls contact the locking pawls in the second region.The rotations take place automatically on account of the contacting of the locking pawls with the connecting elements and preferably by means of the spring force loads. It should be noted that a locking pawl is only rotated when there is contact between the pawl and the locking element. In the case of unlocking, the method steps would be provided as follows:providing the locking mechanism and the locking elements, wherein the locking pawls are contacting the locking element in the second region;actuating the Bowden cable element, whereby the synchronizing axis is rotated and the contacting of the locking pawls and the ratchet pawls in the second region is released;rotation of the locking pawls until contact of the locking pawls with the ratchet pawls is present in the first region.In the case that only one locking pawl is contacted with a locking element during the locking, no rotation of the synchronizing axis takes place. This means that the first end of the Bowden cable element is not moved.The Bowden cable element can preferably be actuated by means of an actuating element. The actuating element is preferably arranged at a second end of the Bowden cable element.Particularly preferably, the actuating element can be provided to actuate the locking mechanism on the one hand and to display an indication about the state of the locking mechanism on the other hand.Specifically, the actuating element can be arranged on the element and have the following properties. Particularly preferably, the actuating element is movable upwards and downwards along the height direction.If the locking mechanism is unlocked, the actuating element is arranged in a first position. The actuating element can preferably be colored green, so that this position can be detected.Upon locking and a corresponding movement of the first end of the Bowden cable element, the actuating element is displaced into a second position. Preferably, this allows a region to be visible which is preferably colored red. In the second position, it can thus be seen that the locking mechanism is correctly locked.Upon unlocking, the actuating element is displaced manually from the second position into the first position, so that the first end of the Bowden cable element is moved accordingly. The red-colored region is no longer visible.In the event that only one locking pawl is contacted with a locking element during locking, the actuating element remains in the first position, since no movement of the first end of the Bowden cable element can be caused.A person can therefore be easily signalled whether the element or the locking mechanism is correctly locked.Further preferably, comfort pawls can also be provided, which are provided and designed to compensate tolerances between the pawls and the locking pawls, so that the locking pawls can be rotated completely into a locking position.Preferably, two comfort pawls are provided, i.e. a first comfort pawl and a second comfort pawl, which are connected to the synchronizing axis such that a slight rotation relative to the synchronizing axis is possible.If the pawl and the locking pawl contact each other in the second region, it is possible that there is a small distance between the pawl and the locking pawl, so that the locking pawl cannot be fully rotated into the locking position. This can occur due to manufacturing tolerances or also due to abrasion. In order to be able to compensate for this small distance, the comfort latches are provided. These have an extension in the radial direction which is necessary to completely rotate the locking pawl. The comfort pawl and the pawl are offset by an angle relative to each other. Further preferably, the comfort pawls are acted upon by a spring force, whereby the comfort pawl can be rotated in such a way that the comfort pawl contacts the second region and rotates the locking pawl into the locking position.Further embodiments and embodiments of the embodiments with respect to one another can be applied to the further embodiments and can be freely combined with one another, provided they do not correspond to embodiments in the opposite direction.Further advantageous embodiments are evident from the dependent claims.The invention is illustrated in more detail below in conjunction with the figures.Other objects, advantages and convenience of the present invention will become apparent from the following description when taken in conjunction with the drawings. The following are shown here: FIG. 1 shows a locking mechanism according to a preferred embodiment in a partial exploded view; FIG. 2 shows the locking mechanism according to FIG. 1 in an assembled and perspective illustration, in a secured locking arrangement; FIG. 3 shows the locking mechanism according to FIG. 1 in an assembled and perspective illustration, in an unlocked locking mechanism; FIGS. 4A-4F show a movement sequence when a locking pawl is locked; FIGS. 5A-5D show the course of movement when the locking of a locking pawl is released; FIG. 6A shows an element with a locking mechanism which is locked on a vehicle floor; FIG. 6B shows a section of the element from FIG. 6A in a secured locking arrangement; FIG. 7A shows the element according to FIG. 6A in an unlocked locking state; FIG. 7B shows the element according to FIG. 6A in the unlocked state.In the figures, identical components are to be understood in each case with the corresponding reference numerals. For the sake of better clarity, in some figures, components may not be provided with a reference sign, which, however, have been designated elsewhere.FIG. 1 shows the locking mechanism 1 according to a preferred embodiment. FIG. 1 shows the locking mechanism 1 in an at least partially exploded view.As can be seen, the locking mechanism 1 has a first locking pawl 2 and a second locking pawl 3. These are mounted rotatably with respect to a locking axis 4, namely about a first axis of rotation 8.Furthermore, a synchronizing axle 5 is provided, wherein a first pawl 6 and a second pawl 7 are arranged on the synchronizing axle 5, which are connected to the synchronizing axle 5 in a rotationally secure manner. This can be realized, for example, by a tongue and groove combination with tongue 18 and groove 19.Likewise, a first comfort pawl 10 and a second comfort pawl 11 are provided, which are likewise connected to the synchronizing axle 5. The comfort pawls 10, 11 are connected to the synchronizing axle 5 in such a way that a slight rotation relative to the synchronizing axle 5 is possible. For this purpose, the comfort pawls 10, 11 each have an elongated hole 20 which can interact with a corresponding further spring of the synchronizing axle 5.The ratchet pawls 6, 7 are arranged at a second distance 22 and the comfort pawls 10, 11 are arranged at a third distance 23 in the width direction B with respect to one another. The comfort pawls 10, 11 are preferably arranged between the pawls 6, 7 or vice versa in the width direction B.The synchronizing axle 5 and the locking axle 4 are rotatably mounted by means of a first holding element 12 and a second holding element 13.For the application of force to the synchronous axis 5, a first torsion spring 14 and a second torsion spring 15 are provided. Preferably, these torsion springs 14, 15 comprise the synchronous axis 5. Preferably, the torsion springs 14, 15 are connected on the one hand to the synchronous axis 5 and on the other hand to a holding element 12, 13 or another fixed element.The first comfort pawl 10 is acted upon by a third torsion spring 16 and the second comfort pawl 11 is acted upon by a force by a fourth torsion spring 17. The torsion springs 16, 17 are connected on the one hand to the synchronizing axle 5 and on the other hand to the respective comfort pawl 10, 11, as a result of which this application of force is independent of the application of force to the synchronizing axle 5.A Bowden cable fastening 24 can be arranged on the synchronizing axis 5, which is provided and designed to receive a first end 26 of a Bowden cable element 25.FIG. 2 shows the locking mechanism 1 according to FIG. 1 in an assembled state with additional components. According to FIG. 2, the Bowden cable element 25 is now shown, as well as a first locking element 27 and a second locking element 28. The locking elements 27, 28 are each arranged rotatably with respect to the vehicle floor 29 so that they can be brought from a parking position, i.e. lowered into the floor, into a locking position, i.e. pivoted completely out of the floor. The locking elements 27, 28 can be configured in the manner of eyes.Likewise, according to FIG. 2, a first tension spring 30 and a second tension spring 31 are shown. The first tension spring 30 is connected on the one hand to the first locking pawl 2 and on the other hand to the first holding element 12 or another fixed element. The second tension spring 31 is connected on the one hand to the second locking pawl 3 and on the other hand to the second holding element 13 or another fixed element. The fixed element here preferably refers to a portion of the element, for example the box element. Preferably, the locking mechanism 1 is connected to the element in a fixed position by means of the holding elements 12, 13.FIG. 2 further shows the locking position, i.e. that both locking pawls 2, 3 are in contact with the respective locking element 27, 28.FIG. 3 shows the situation in which the locking mechanism 1 is in contact only with one of the locking elements 27, 28. The first locking element 27 is in the locking position, and the second locking element 28 is in the parking position. Since the two locking pawls 2, 3 are rotatable independently of each other, only the first locking pawl 2 is locked.A receptacle 32 can now also be seen, by means of which the first end 26 of the Bowden cable element 25 is connected to the synchronous axle 5.The receptacle 32 is spaced apart from the synchronizing axis in the radial direction thereof, whereby a lever is produced which facilitates the rotation of the synchronizing axis 5.According to FIGS. 4A to 4D, the movement sequence during the locking of a latch element 2, 3 is shown.The latch elements 2, 3 preferably comprise a U-shaped hook element 33 with a first leg 34 and a second leg 35. The hook element 33 is arranged such that the legs 34, 35 can move substantially on a circular path about the first axis of rotation 8. Particularly preferably, the locking pawl 2, 3 can be brought into contact with the locking element 27, 28 particularly well if the first leg 34 is longer than the second leg 35 and the first leg is arranged closer to the first axis of rotation 8 as viewed in the radial direction. An opening 36 of the hook element 33, i.e. a free space 36 between the legs 34, 35, can thus be brought into good contact with the eyelet-like locking element 27, 28.A locking part 39 opposite the hook element 33 with respect to the axis of rotation 8 is provided and configured to interact with the pawl 6, 7 or with the comfort pawl 10, 11. For this purpose, the locking part 39 has a first region 37 and a second region 38. The first region 37 is substantially a circular arc with the center of the axis of rotation 8. The same applies likewise to the second region 38 and a corresponding fourth region 41 of the latches 6, 7, 10, 11. Accordingly, the fourth region 41 is perpendicular to the third region 40.The mode of operation is illustrated in more detail in the following figures.Specifically for the course of the movement, the locking mechanism 1 is shown in an unlocked state in FIG. 4A, that is to say there is no contact between the locking pawl 2, 3 and the locking element 27, 28.If, as shown in FIG. 4B, the locking mechanism 1 is now moved in the direction of the vehicle floor 29, shown by the arrow, the locking pawl 2, 3 and the locking element 27, 28 contact one another, as a result of which a rotation of the locking pawl 2, 3 is caused, in the present case in a first rotational direction DR 1, which in the present case corresponds in the clockwise direction. Accordingly, the locking part 39 moves. The first region 37 now moves with respect to the third region 40 and the hook element 33 moves in the direction of the locking element 27, 28 and starts to receive the locking element 27, 28 in the opening 36.The locking pawl 2, 3 is rotated until the first region 37 and the third region 40 no longer contact each other. The hook element 33 now fully engages the locking element 27, 28. Due to the spring-loaded arrangement of the synchronizing axis 5, the synchronizing axis 5 with the ratchet pawls 6, 7 now rotates about the second axis of rotation 9 likewise in the first direction of rotation DR 1, as illustrated in FIG. 4C. The synchronizing axis 5 or the pawl 6, 7 now rotates in the direction DR 1 until the pawl 6, 7 contacts the second region 38 by means of the fourth region 41, as shown in FIG. 4D. The locking mechanism 1 is now locked.In accordance with the movement of the synchronizing axle 5, the first end 26 of the Bowden cable element 25 also rotates with it, namely by means of the Bowden cable fastening 24.The movement of the locking pawl 2, 3 stretches the corresponding tension spring 30, 31.It is also shown that the comfort pawl 10, 11 is arranged at an angle 43 to the pawl 6, 7. As can be seen in FIG. 4D, the pawl 6, 7 is slightly too small, represented by the distance 42, to rotate the locking pawl 2, 3 into the fully locked position or state. Since the comfort pawl 10, 11 is designed to be radially longer than the pawl 6, 7 and is likewise acted upon by force as described and permits a slight rotation with respect to the synchronizing axis 5, the comfort pawl 10, 11 can rotate further in the direction DR 1 and the locking pawl 2, 3 can rotate further in the direction DR 1.The function of the comfort pawl 10, 11 is shown even more precisely in FIGS. 4E and 4F.FIG. 4E shows the situation that the pawl 6, 7 contacts the second region 38, but the locking pawl 2, 3 is not completely rotated into the locked position. There is therefore still a degree of freedom with respect to the rotation of the locking pawl 2, 3, but at the same time no rotation of the pawl 6, 7 is possible.Due to the configuration of the comfort pawl 10, 11, the comfort pawl 10, 11 can rotate even further and thus the locking pawl 2, 3 can now rotate into the fully locked position. This is illustrated in FIG. 4F. The tolerance 47 of the locking mechanism 1 can therefore be compensated.The angle 43 between the comfort pawl 10, 11 and the pawl 6, 7 is variable, as can be seen from a comparison of FIGS. 4E and 4F.The comfort pawl 10, 11 is preferably likewise configured with the third region and the fourth region, and as already mentioned, however, is configured to be longer in the radial direction than the pawl 6, 7.FIGS. 5A to 5D show the movement sequence during unlocking of the locked locking mechanism 1.FIG. 5A corresponds to FIG. 4D, i.e. to the locked state. It is now necessary to guide the pawl 6, 7 out of the second region 38. For this purpose, the Bowden cable element 25 is actuated. This means that the synchronizing axis 5 can be rotated in the direction DR2, i.e. in the counterclockwise direction, so that the latches 6, 7, 10, 11 are led out of the second region 38.If the locking pawl 2, 3 and the pawl 6, 7 and the comfort pawl 10, 11 no longer contact one another, the locking pawl 2, 3 is reset in the direction DR 2 due to the tension spring 30, 31, so that the situation of FIG. 4B is initially restored and the situation of FIG. 4A is finally restored. The locking mechanism 1 and the locking elements 27, 28 are detached from each other and the element can be removed.FIG. 6A shows the element E or the box element E, which can be arranged on a vehicle floor 29 and locked to it.FIG. 6B shows a detail of the element E with the actuating element 44 for actuating the Bowden cable element. FIG. 6B corresponds to the locked representation according to FIG. 6A.The element E preferably has a planar upper side 45, wherein the actuating element 44 is flush with the upper side 45 in the case of a correct locking. Likewise, the actuating element 44 can be colored, for example green. This allows the person to be visually and haptically informed that the element E is correctly locked.In FIGS. 7A and 7B, an unlocked position can be seen and the element E is spaced apart from the vehicle floor 29. To unlock the locking mechanism 1, the Bowden cable element 25 has been actuated by means of the actuating element 44, for example pressed downward as shown. The actuating element 44 is no longer flush with the upper side 45. The pressing down of the actuating element 44 has now revealed a visible region 46 which can be colored differently in color than the actuating element 44, for example red. This allows the person to be visually and haptically informed that the element E is unlocked.In the event that the locking mechanism 1 is not locked correctly but the element E contacts the vehicle floor 29, the situation according to FIG. 7A is furthermore illustrated since the synchronizing axle 5 cannot rotate. This also allows feedback to be given that the locking has not been carried out correctly. The reason here can be a non-folded locking element 27, 28, as shown in FIG. 3.All the features listed can be combined with one another in any desired manner.List of reference characters1 Locking mechanism 2 First locking pawl 3 Second locking pawl 4 Locking axis 5 Synchronous axis 6 First locking pawl 7 Second locking pawl 8 First rotational axis 9 Second rotational axis 10 First comfort pawl 11 Second comfort pawl 12 First retaining element 13 Second retaining element 14 First torsion spring 15 Second torsion spring 16 Third torsion spring 17 Fourth torsion spring 18 First groove 19 First spring 20 Elongated hole 21 First distance 22 Second distance 23 Third distance 24 Bowden cable fastening 25 Bowden cable element 26 First end of the bowden cable element 27 First locking element 28 Second locking element 29 Vehicle floor 30 First tension spring 31 Second tension spring 32 Receptacle 33 Hook element 34 First leg 35 Second leg 36 Opening, Clearance 37 First region 38 Second region 39 Locking part 40 Third region 41 Fourth region 42 Distance 43 Angle 44 Actuating element 45 Upper side 46 Viewing region 47 Tolerance DR 1 First rotational direction DR 2 Second rotational direction E Element, box element H Height direction B Width direction L Longitudinal direction
