Abstract
Description
[0001] The invention relates to a connecting arrangement for connecting a wiper blade to a wiper arm for a windshield wiper system of a vehicle. An adapter of the wiper blade comprises an upper part designed as a rocker and a lower part designed as a slider, wherein the slider is pivotably mounted on the rocker about a rotational axis and holds a wiper body of the wiper blade. The adapter can be secured to the wiper arm by means of the rocker. A slider of the connecting arrangement engages around an end region of the wiper arm, wherein the slider can be displaced along the wiper arm from an installed position into a functional position. In the functional position of the slider, the adapter is held on the wiper arm by means of the slider. The wiper blade has a securing device for securing the slider in its functional position. The invention further relates to a wiper blade for such a connecting arrangement.
[0002] DE 10 2013 019 805 A1 describes a connecting assembly for connecting a wiper blade to a wiper arm for a windshield wiper system of a vehicle. A securing element for securing a slider of the connecting assembly in its functional position holding an adapter of the wiper blade is arranged on a lower part of the adapter designed as a slider.
[0003] To detach the wiper blade from the wiper arm, you first need to fold the wiper arm away from the vehicle's windshield and then pivot the wiper blade into a position where the locking element releases the slider. The slider can then be moved into an assembly position, allowing the wiper blade to be detached from the wiper arm.
[0004] Such handling of the connecting arrangement for detaching the wiper blade from the wiper arm requires a certain degree of skill on the part of a user who wishes to disassemble the wiper blade from the wiper arm.
[0005] US 11 814 018 B2 also discloses an arrangement for connecting the wiper arm to the wiper blade by means of an adapter for a vehicle's windshield wiper system. This adapter creates a connection between the wiper arm and wiper blade through a sequence of movements. Detaching the wiper blade requires several steps that must be carried out sequentially. First, the securing device must be released to allow subsequent translational movement of the slider. This then causes the adapter to rotate, creating sufficient space for the wiper blade to be detached from the wiper arm. Attaching a wiper blade is done in a similar way: the adapter is rotated in the opposite direction, resulting in a sliding movement until the elastic securing element engages.The described arrangement hooks onto the wiper arm with a component at the front end of the adapter, thus creating the connection.
[0006] In particular, due to the complex movement sequence described for attaching or detaching a wiper blade to the wiper arm, operation is not entirely intuitive and requires skill when installing or removing the wiper arm. In addition, the adapter must be rotated around a pivot axis before or after performing a sliding movement. The pivot axis around which the adapter rotates is particularly susceptible to wear or improper use.
[0007] The object of the present invention is to provide a connecting arrangement of the type mentioned at the outset, in which replacement of the wiper blade is particularly easy to accomplish, and to provide a wiper blade for such a connecting arrangement.
[0008] This object is achieved by a connecting arrangement having the features of patent claim 1 and by a wiper blade having the features of patent claim 10. Advantageous embodiments with expedient further developments of the invention are specified in the dependent patent claims and in the following description.
[0009] In the connecting arrangement according to the invention for connecting a wiper blade to a wiper arm for a windshield wiper system of a vehicle, an adapter of the wiper blade comprises an upper part designed as a rocker and a lower part designed as a slider. The slider is mounted on the rocker so as to be pivotable about a rotational axis and holds a wiper body of the wiper blade. The adapter can be secured to the wiper arm by means of the rocker. A slider of the connecting arrangement engages around an end region of the wiper arm, wherein the slider can be displaced along the wiper arm from an installed position into a functional position. In the functional position, the adapter is held on the wiper arm by means of the slider. The wiper blade has a securing device for securing the slider in its functional position. The securing device is arranged on the rocker and can be moved from a locking position securing the slider into a release position.When the safety device is moved into the release position, the slider can be moved along the wiper arm into the assembly position.
[0010] In contrast, the locking device, in its locked position, ensures that the slider cannot be moved, or at least not easily, along the wiper arm. However, due to the positioning of the locking device on the rocker, the slider can be moved from the functional position to the assembly position when the locking device is moved into the release position, without the wiper blade necessarily having to be brought into a specific alignment with the wiper arm. Rather, it is sufficient to move the locking device from the locked position, in which the locking device secures the slider in its functional position, to the release position. This makes replacing the wiper blade particularly easy.
[0011] In particular, the wiper blade can be replaced or changed without having to completely fold the wiper arm away from the windshield. This is advantageous in terms of a simple and intuitive replacement or change of the wiper blade.
[0012] Furthermore, it is advantageous that the safety device is located on the replacement part in the form of the wiper blade. This means that every time the wiper blade is replaced, the safety device is also replaced. Therefore, if the safety device becomes worn, this wear part is replaced at the same time as the wiper blade.
[0013] In addition, the movement of the safety device arranged on the rocker from the locking position to the release position is particularly intuitive and easy to understand for a user of the connection arrangement, so that incorrect operation when replacing or changing the wiper blade is largely excluded.
[0014] If the wiper blade is designed as a flat-blade wiper or a bar wiper, the tab of the adapter can directly hold a substructure of the flat-blade wiper or a bar wiper, whereby the substructure has a wiper lip of the wiper body.
[0015] And if the wiper blade is designed as a bracket wiper, the tab can hold one bracket of the wiper body. In this case, further brackets of the wiper body can be held by the bracket, with the other brackets in turn supporting a wiper body substructure. Here, too, the wiper body substructure has a wiper lip.
[0016] The user can preferably detect the locking position of the safety device haptically, acoustically, and / or visually. This is also advantageous with regard to simple and intuitive operation when mounting and dismounting the wiper blade of the connecting arrangement to the wiper arm of the connecting arrangement or from the wiper arm of the connecting arrangement.
[0017] Preferably, the safety device is formed integrally with the base body of the rocker. This allows the safety device to be incorporated very easily and with minimal effort in a single operation during the manufacture of the rocker.
[0018] The securing device preferably has at least one locking element, which engages behind a portion of the slider in the locking position of the securing device. In particular, the provision of the locking element makes it possible for a user of the connecting arrangement or similar operator to detect haptically and acoustically that the slider has locked into its functional position. If the locking element is also visible in the locking position of the securing device, the user is also given visual feedback that the securing device is in the locking position.
[0019] Preferably, the slider has a U-shaped cross-section with a back and two legs. This allows the slider to easily grip the end of the wiper area and thus be moved along the end of the wiper arm.
[0020] The at least one locking element can engage in at least one recess formed in the back of the slider. This allows the engagement of the locking element in the recess to be clearly perceived haptically when the user slides the slider along the end region of the wiper arm into the functional position.
[0021] If the recess in the back of the slider is designed as a through-opening, the user can also visually determine whether the locking element is located in the recess or engages the recess. This makes it particularly easy for the user to visually detect when the safety device has reached its locked position.
[0022] Additionally or alternatively, the at least one locking element can be formed in at least one of the legs of the slide. This allows the end region of the wiper arm to be designed particularly simply. In particular, no through-opening for the locking element needs to be provided in the back of the end region of the wiper arm. This is advantageous with regard to the high robustness of the wiper arm, particularly in its end region.
[0023] Furthermore, the user can easily detect haptically that the locking device has reached the locking position when the at least one locking element engages in the recess formed in at least one leg of the slider. This is because the slider can be particularly well gripped on the two legs to move the slider from the assembly position to the functional position and back.
[0024] The recess formed in the back of the slider can be designed as a through-opening, which, in the slider's functional position, aligns with a through-opening formed in the end region of the wiper arm. Thus, when the slider is moved along the end region of the wiper arm, it can be determined that the slider will immediately reach its functional position as soon as the through-opening formed in the end region of the wiper arm becomes visible through the through-opening formed in the back of the slider. This is advantageous.
[0025] Preferably, a respective recess is formed in each of the two legs of the slider, wherein, in the functional position of the slider, a first locking element of the securing device engages in the recess formed in a first leg and a second locking element of the securing device engages in the recess formed in a second leg. By providing the two recesses and the two locking elements corresponding to the two recesses, a particularly high level of security can be achieved, which the securing device has in the locked position. In addition, the holding forces to be exerted by the securing device in the locked position can be very effectively distributed between the two locking elements.
[0026] Preferably, the at least one locking element is connected to a base body of the rocker via at least one elastically deformable arm. Elastic deformation of the at least one arm can be achieved by moving the slider along the wiper arm from the assembly position to the functional position. This makes moving the slider from the assembly position to the functional position particularly easy. This is because, during this movement of the slider along the wiper arm, the at least one arm is elastically deformed.
[0027] And when the at least one arm springs back into its undeformed starting position, the at least one locking element engages in the locking position of the securing device, with the locking element engaging behind the partial area of the slide. This allows for particularly secure fixation of the slide in its functional position. In particular, the locking element can engage in the at least one recess in the locking position.
[0028] Preferably, the first locking element is connected to the at least one elastically deformable arm via a first retaining web, and the second locking element is connected to the at least one elastically deformable arm via a second retaining web. This makes it particularly easy to ensure that the deformation of the elastically deformable arm is accompanied by a corresponding movement of the locking elements. This is advantageous.
[0029] Preferably, the retaining bars are at least partially concealed by the end of the wiper arm when the slider is in the functional position. This provides good protection for the retaining bars and significantly reduces wear on the retaining bars.
[0030] It has also been shown to be advantageous if the at least one locking element engages behind a front wall of the slider in the locking position of the securing device. In this case, the front wall can be moved toward a front side of the end region of the wiper arm by moving the slider from the assembly position into the functional position. This makes it particularly easy for an observer looking at the front wall of the slider to visually detect when the securing device or the at least one locking element has reached the locking position. This is advantageous.
[0031] Preferably, a positive connection is provided by engaging the partial area of the slider by means of the at least one locking element. This ensures particularly reliable securing of the slider in the functional position by means of the securing device.
[0032] Alternatively or additionally, in particular alternatively, it can be provided that a force-locking connection is formed between the at least one locking element and the partial area of the slider engaged behind by the locking element in the locking position of the securing device. In this case, the force-locking connection can be released by sliding the slider along the wiper arm from the functional position into the assembly position. In this way, moving the slider from the functional position into the assembly position is particularly easy. This is because all that is required is a strong pull on the slider to move the securing device into the release position. In this way, moving the securing device into the release position and releasing the slider from the functional position can be achieved in a single operating process.This is advantageous in terms of easy operation of the connection arrangement when changing or replacing the wiper blade.
[0033] The wiper blade according to the invention is intended for use in the connecting arrangement according to the invention. Here, an adapter of the wiper blade comprises an upper part designed as a rocker and a lower part designed as a slider. The slider is pivotally mounted on the rocker about a rotation axis and holds a wiper body of the wiper blade. The adapter can be secured to a wiper arm of the connecting arrangement by means of the rocker, wherein a slider of the connecting arrangement is designed to engage around an end region of the wiper arm. The slider can be displaced along the wiper arm from an installed position into a functional position, in which the adapter is held on the wiper arm by means of the slider. The wiper blade has a securing device for securing the slider in its functional position.The locking device is arranged on the rocker and can be moved from a locking position securing the slider to a release position. With the locking device moved to the release position, the slider can be moved along the wiper arm into the assembly position. Replacing a wiper blade of this type is particularly easy.
[0034] The advantages and preferred embodiments described for the connection arrangement according to the invention apply analogously to the wiper blade according to the invention.
[0035] Further advantages, features, and details of the invention will become apparent from the following description of preferred embodiments and from the drawings.

[0037] In the figures, identical or functionally identical elements are provided with the same reference symbols.
[0038] In Fig. Figure 1 shows a partial perspective view of a connecting arrangement 10 for connecting a wiper blade 12 to a wiper arm 14 for a windshield wiper system of a vehicle. The wiper blade 12 comprises an adapter 16 with an upper part designed as a rocker 18 and a lower part designed as a tab 20.
[0039] The rider 20 is pivotably mounted on the rocker 18 about a pivot axis or rotation axis 22. This allows, when the adapter 16 is in an end region 24 of the wiper arm 14 (compare Fig. 2) is fixed to the wiper arm 14, the rider 20 can be pivoted relative to the rocker 18 about the axis of rotation 22 and in doing so follow a curvature of the windscreen of the vehicle to be wiped.
[0040] The tab 20 of the adapter 16 holds a wiper body 26 of the wiper blade 12, wherein the wiper body 26 has a wiper lip 28 which is moved over the windscreen of the vehicle to be wiped during wiping operation of the windscreen wiper system.
[0041] In order to fix the wiper blade 12 to the wiper arm 14 in its end region 24 (compare Fig. 2), the adapter 16 is inserted into a receptacle formed in the end region 24 of the wiper arm 14, essentially perpendicular to a surface which is swept over by the wiper body 26 of the wiper blade 12 during wiping operation of the windscreen wiper system. A mounting direction 30 when inserting or introducing the adapter 16 into the end region 24 of the wiper arm 14 is shown in Fig. 1 and in Fig. 2 is illustrated by an arrow.
[0042] A slider 32 or sliding latch is arranged on the wiper arm 14 and is displaceable along the end region 24 of the wiper arm 14. The sliding latch or slider 32 has respective locking strips 34, which encompass the wiper arm 14 in the end region 24. In Fig. 2 shows one of these closure strips 34. A gap 36 or interruption is formed in the respective closure strip 34. The interruption 36 is located at the level of a recess 38 formed in a side wall 39 of the wiper arm 14 in the end region 24 when the slide 32 is in its Fig. 1 and in Fig. 2 shown assembly position.
[0043] The respective closure strip 34 engages under the respective side wall 39 of the wiper arm 14 in the end region 24 of the wiper arm 14. As a result, an extension arm 42 formed on the rocker 18 and projecting in the direction of the rotation axis 22 from a base body 40 of the rocker 18 can be inserted into the recess 38 which is formed in the respective side wall 39 of the wiper arm 14 in its end region 24. The two extension arms 42 projecting from the base body 40 of the rocker 18 can be inserted in the assembly direction 30 into the corresponding recesses 38 when the slider 32 is in the Fig. 2. This is because the interruptions 36 in the locking strip 34 are aligned with the recesses 38 in the assembled position of the slide 32.
[0044] If the slider 32 or sliding bar is then moved along the wiper arm 14 in a direction which Fig. 3 is illustrated by an arrow 44, the arms 42 rest on the locking strips 34 of the slider 32. As a result, the adapter 16 is held on the wiper arm 14 by means of the slider 32.
[0045] In order to secure the slider 32 in its functional position, in which the arms 42 rest on the locking strips 34 of the slider 32, the wiper blade 12 has a securing device 46 which is arranged on the rocker 18.
[0046] A first variant of the safety device 46 is shown by way of example in Fig. 1. The securing device 46 comprises a locking element 48, which is connected to the base body 40 of the rocker 18 via an elastically deformable arm 50.
[0047] For example, Fig. 1 is in connection with Fig. 2 clearly shows that the slider 32 has a U-shaped cross-section with a back 52 and two legs 54, 56 projecting downward from the back 52. The respective locking strips 34 are formed on the two legs 54, 56, which engage around the underside of the side walls 39 of the wiper arm 14 in its end region 24.
[0048] At the Fig. 1 to Fig. In the variant of the connecting arrangement 10 shown in Figure 7, a recess 58 corresponding to the locking element 48 is formed in the back 52 of the slide 32. The recess 58 can, unlike in Fig. 1 to Fig. 7, be designed to be closed towards an upper side of the back 52, so that the recess 58 is not visible to an observer looking at the back 52 of the slider 32.
[0049] At the Fig. 1 to Fig. In the variant of the connecting arrangement 10 shown in Fig. 7, the recess 58 formed in the back 52 of the slide 32 is, in contrast, designed as a passage opening which, in the functional position of the slide 32 (cf. Fig. 4) is aligned with a passage opening 60 which is formed in the end region 24 of the wiper arm 14 (compare in particular Fig. 1 and Fig. 2). Through this passage opening 60, the locking element 48, designed in the manner of a locking lug, can engage into the recess 58 formed in the back 52 of the slide 32.
[0050] Out of Fig. 3 shows how, by pushing the slider 32 back in the direction of arrow 44, the elastic arm 50 is initially bent downward. When the recess 58 is then aligned with the through-opening 60, the locking element 48 snaps into the recess 58. The slider 32 has now reached its end position or functional position, in which the wiper blade 12 is secured against detachment from the wiper arm 14. Furthermore, the securing device 46 is in a locking position that secures the slider 32.
[0051] The engagement of the locking element 48 in the recess 58 is in the Fig. 1 to Fig. 7 shown variant of the connecting arrangement 10 can be perceived haptically and acoustically by a user or such an operator. A corresponding clicking sound is in Fig. 4 by a symbol 62. In addition, the engagement of the locking element 48 in the recess 58 is optically detectable. This is because an upper section of the locking element 48 is visible through the recess 58, which is formed in the back 52 of the slider 32 (compare Fig. 4 and Fig. 5).
[0052] According to Fig. 1, the securing device 46 has two actuating cheeks 64, which can be actuated to move the securing device 46 into a release position. When the securing device 46 is in the release position, the slide 32 can be moved along the wiper arm 14 into the Fig. 1 and Fig. 2. The two actuating cheeks 64 rest against the outer sides of the side walls 39 of the wiper arm 14, wherein the side walls 39 delimit the receiving space for the adapter 16 in the transverse direction or width direction of the wiper arm 14.
[0053] In Fig. 1 and in Fig. 5 only one of the two actuating cheeks 64 is visible. However, Fig. 14 shows that the Fig. 1 preferably has two actuating cheeks 64. In the case of the Fig. 14 shown variant of the securing device 46 are only instead of the one elastically deformable arm 50 (compare Fig. 1) two elastically deformable arms 50 are provided, which connect the locking element 48 to the base body 40 of the rocker 18.
[0054] Out of Fig. 6 shows how the two actuating cheeks 64 are moved in the direction of a Fig. 6 shown arrow 66 downwards in order to disengage the locking element 48 from the recess 58. As a result, the securing device 46 is in the release position, and the slider 32 can be moved along the end region 24 of the wiper arm 14 into the assembly position, specifically in the direction of a further arrow 68, which in Fig. 7. The arrow 68 according to Fig. 7 is according to arrow 44 Fig. 3 opposite.
[0055] As soon as the arms 42 of the rocker 18 are at the height of the interruptions 36 formed in the locking strips 34 (see Fig. 1 and Fig. 2), the adapter 16 can be removed from the end region 24 of the wiper arm 14, in the opposite direction to the mounting direction 30, which in Fig. 1 and in Fig. 2 is illustrated by the respective arrow.
[0056] At the Fig. In the variant of the securing device 46 shown in Fig. 8, the securing device 46 has two locking elements 70, 72 which, in the locking position of the securing device 46, engage in respective recesses 74 formed in the two legs 54, 56 of the slide 32.
[0057] In Fig. 9 to Fig. 11 only the recess 74 formed in the first leg 54 is visible. However, the opposite second leg 56 also has a corresponding recess 74, into which the other locking element 70 of the Fig. 8 shown safety device 46 engages when the safety device 46 is in the position shown in Fig. 9 shown locking position.
[0058] In this variant, the locking elements 70, 72 also provide the actuating cheeks, which the user can engage in order to move the elastic arm 50 of the Fig. 8 shown securing device 46 downwards. The locking elements 70, 72 can be grasped, for example, with the thumb and index finger of one hand of the user and moved downwards out of the corresponding recesses 74, as shown in Fig. 10 is illustrated by a curved arrow 76.
[0059] Due to this downward movement of the locking elements 70, 72 out of the recesses 74 formed in the two legs 54, 56 of the slide 32, the securing device 46 is in the release position. Therefore, the slide 32 can be moved along the wiper arm 14 into the assembly position. This displacement movement of the slide 32 is also in Fig. 11 by the arrow 68, which corresponds to Fig. 7 corresponds to arrow 68.
[0060] Out of Fig. 8 further shows that the locking elements 70, 72 are connected to the elastically deformable arm 50 via respective retaining webs 78, 80. The first locking element 70 is connected to the elastically deformable arm 50 via a first retaining web 78. And the second locking element 72 is connected to the elastically deformable arm 50 via a second retaining web 80. In the functional position of the slider 32 (cf. Fig. 9), the retaining webs 78, 80 are concealed by the end region 24 of the wiper arm 14. In particular, the retaining webs 78, 80 are arranged adjacent to the inner sides of the side walls 39 of the end region 24 of the wiper arm 14.
[0061] At the Fig. In the variant of the securing device 46 shown in Figure 12, the locking element 48 is formed in a front side of the rocker 18. In this variant, too, the locking element 48 is connected to the base body 40 of the rocker 18 via an elastically deformable arm 50. However, in the locking position of the securing device 46, the locking element 48 engages behind a front wall 82 of the slide 32, as shown in Fig. 13 is shown.
[0062] The front wall 82 of the slider 32 is moved when the slider 32 is moved from the assembly position (compare Fig. 1) to a front side 84 (compare Fig. 2) of the end region 24 of the wiper arm 14. In contrast, in the assembled position of the slide 32, the front wall 82 is further spaced from the end face 84 of the end region 24 of the wiper arm 14.
[0063] The Fig. The variant of the safety device 46 shown in Figure 15 corresponds very largely to that shown in Fig. 8 shown variant of the safety device 46. However, the retaining webs 78, 80 here merge into a bridge part 86, which is connected to the base body 40 of the rocker 18 via two separate elastically deformable arms 50. Thus, instead of a wide, tongue-like arm 50 (compare Fig. 8) the two narrower arms 50 are provided.
[0064] In an analogous manner, the Fig. 16 shown variant of the safety device 46 very largely corresponds to the Fig. 12 shown variant of the safety device 46. However, here too the locking lug or the locking element 48, which is designed to engage behind the front wall 82 of the slide 32 (compare Fig. 13) does not have an elastic arm 50 (compare Fig. 12), but is connected to the base body 40 of the rocker 18 via two separate elastic arms 50.
[0065] Fig. 17 shows a further variant of the safety device 46, which is similar to the Fig. 1 is very similar to the variant of the securing device 46. However, here the locking element 48 has an inclined surface 88 at its end remote from the base body 40, which slopes down to a straight end face 90 of the locking element 48.
[0066] A rear boundary wall 92 of the recess 58 can press against this inclined surface 88 when the slide 32 is moved into its assembly position in the direction indicated by the arrow 68. As a result, the elastic arm 50 is bent downwards, as shown in Fig. 18 is illustrated by a further curved arrow 94.
[0067] Accordingly, in the Fig. 17, the variant of the securing device 46 does not appear to be provided with the actuating cheeks 64. Rather, it is sufficient to forcefully pull the slide 32 forward in the direction indicated by the arrow 68 in order to move the securing device 46 into the release position, in which the locking element 48 is disengaged from the recess 58 formed in the back 52 of the slide 32.
[0068] In an analogous manner, the Fig. 19 shown variant of the safety device 46 very largely corresponds to the Fig. 8 shown variant of the safety device 46. However, here too, respective inclined surfaces 88 are formed on the two locking elements 70, 72, which slope down towards a rear end of the safety device 46. Here too, the locking elements 70, 72 do not need to be designed in the manner of the actuating cheeks 64 (cf. Fig. 6) to be moved downwards in order to cause a corresponding elastic deformation of the arm 50.
[0069] Rather, it is sufficient to move the slider 32 forcefully in the direction which Fig. 20 is illustrated by the arrow 68. As a result, the actuating surfaces 96 provided in the area of the recesses 74 press the two locking elements 72, 70 downwards, so that the securing device 46 is in its release position. Consequently, in this variant too, the inclined surfaces 88 ensure that the force-locking connection of the locking elements 70, 72 with the recesses 74 is released when the slide 32 is moved in the direction indicated in Fig. 20 is illustrated by the arrow 68.
[0070] In a similar way, the Fig. 21 shown variant of the safety device 46 very largely corresponds to the Fig. 12 shown variant of the safety device 46. However, even in the Fig. 21, an inclined surface 88 is formed on the locking element 48, which faces the front wall 82 of the slide 32. Thus, if the slide 32 is moved into the position shown in Fig. 22 is pulled forward vigorously in the direction illustrated by the arrow 68, a lower section of the front wall 82 exerts a pressure on the inclined surface 88, which leads to an elastic deformation of the arm 50.
[0071] The locking element 48 is pressed downwards, as shown in Fig. 22 by a further curved arrow 98. This moves the safety device 46 into the release position, which allows the slide 32 to be moved further into the position indicated by the arrow 68 in Fig. 22, namely into the assembly position.
[0072] At the Fig. In the variant of the securing element or securing device 46 shown in Figure 4, the locking element 48 protrudes through the passage opening 60, which is formed in an upper wall of the wiper arm 14 in the end region 24. In this variant, the locking element 48 is actuated by means of the actuating cheeks 64 or pressure cheeks to move the securing device 46 into the release position.
[0073] At the Fig. In contrast, in the variant of the securing element 46 shown in Fig. 8, the locking elements 70, 72 also form the actuating cheeks, which the user can engage in order to move the elastic arm 50 downwards.
[0074] And at the Fig. In the variant shown in Figure 12, the flexible locking element 48 is incorporated into a front region of the rocker 18 and, as a partial region of the slide 32, engages behind the front wall 82 of the slide 32.
[0075] In all of these variants, the slider 32 or sliding latch engages with at least one flexible locking element 48, 70, 72 when the slider 32 is moved from the assembly position into the functional position. In this case, the slider 32 initially presses the respective locking element 48, 70, 72 downwards. The locking element 48, 70, 72 then engages behind the respective portion of the slider 32, either by engaging the recess 58 in the back 52 of the slider 32 (see Fig. 4) or by engaging in the recesses 74 in the legs 54, 56 of the slide 32 (compare Fig. 9) or by engaging behind the front wall 82 of the slide 32 (compare Fig. 13). In these variants, the locking mechanism of the slide 32 is designed to be positively locked.
[0076] However, if the respective locking element 48, 70, 72 is bevelled or has at least one bevelled surface 88 (compare Fig. 17, Fig. 19 and Fig. 21), a force-locking connection is formed, which is achieved by a strong forward pushing of the slider 32 in the direction indicated by the arrow 68 (compare Fig. 18, Fig. 20 and Fig. 22) can be solved.
