Abstract
Description
Technical Field
[0001] The invention relates to a connecting device for assembling a wiper blade to a wiper arm. Another subject of the invention is a wiper device comprising a wiper arm, a wiper blade and a connecting device of the wiper blade to the wiper arm. Background Art
[0002] Motor vehicles are often equipped with wiper systems for cleaning their glass-paneled surfaces, particularly their windshields. Such wiper systems comprise a wiper arm and a wiper blade driven by the arm. The wiper arm is connected to the vehicle's motor, while the wiper blade comprises at least one wiper rubber element designed to contact the glass-paneled surface to be wiped. To enable the wiper blade to be driven, a connection system is arranged between the wiper arm and the wiper blade's connector.
[0003] There are various types of arms, such as hook arms, arms with lateral pivot pins, arms with longitudinal clip-on fasteners, lever arms, vertical locking arms, and more.
[0004] Thus, the connection system is specifically configured to cooperate with the vertical locking arms.
[0005] Since there are also various types of vertical locking arms, which differ in particular in their dimensions and in the position of the opening for cooperating with the locking button, a combination of adapters is used in some cases.
[0006] A first connection system is known comprising a first adapter and a module mounted on the first adapter, the first adapter comprising a flexible tab bearing a first locking button configured to lock the first connection system to a first type of wiper arm.
[0007] A second connection system is also known, comprising a second adapter mounted on the first adapter, the second adapter having a flexible tab supporting a second locking button configured to lock the assembly of the stacking adapter with a second type of wiper arm. The second adapter has a very thin and flexible design so as to be insertable between the first adapter and the arm.
[0008] When the stacking adapter is assembled in the yoke of the wiper arm, it is desirable that the adapter remain assembled to the yoke even when subjected to tension (which the user would apply). This could occur, for example, if the windshield is icy. When the wiper blade remains stuck to the windshield, the user attempts to separate the blade from the windshield by pulling upward on the wiper arm.
[0009] A vertical pulling force applied to the arm would cause the second locking button to be pulled upwards, which risks the locking button coming loose or the flexible tab supporting the second locking button breaking. Summary of the Invention
[0010] One of the objects of the present invention is to propose a connection device which makes it possible to prevent the wiper blade from being separated from the wiper arm in the event of a pulling force exerted by the wiper arm.
[0011] To this end, a subject of the invention is a connecting device for assembling a wiper blade to a wiper arm, comprising: - a first adapter comprising a flexible tab supporting a first locking button having a locking lug, and a second adapter configured to be mounted on the first adapter and configured to be inserted between the first adapter and the wiper arm, the second adapter having a flexible tab supporting a second locking button configured to lock the assembly of the second adapter with the wiper arm, It is characterized in that the flexible tab of the second adapter also supports a retaining fin, which is arranged below the second locking button and extends below the locking lug of the first locking button, and the retaining fin engages with the locking lug of the first locking button of the first adapter so that the first locking button moves together with the second locking button when a pulling force is applied to the second locking button.
[0012] When the second locking button is engaged with the first locking button, the strength of the second flexible tab supporting the second locking button is reinforced by the strength of the flexible tab supporting the first locking button. This takes advantage of the stackable adapter of the connection device and the fact that the first locking button of the first adapter has a locking lug for locking the first type of wiper arm in order to increase the rigidity of the second adapter.
[0013] The connecting device may further comprise one or more of the features described below, which may be considered individually or in combination.
[0014] According to an exemplary embodiment, the retention fins are plate-shaped.
[0015] According to an exemplary embodiment, when the retention fin is engaged with the locking tab, the end of the retention fin of the second adapter is spaced between 0.1 mm and 3 mm from the folded portion of the locking tab of the first adapter.
[0016] According to an exemplary embodiment, when the retention fin is engaged with the locking lug, the locking lug is configured to move forward on the retention fin when the locking button is raised. The greater the pulling force, the more the first locking button moves forward on the retention fin, and the greater the degree to which vertical retention can be improved.
[0017] According to an exemplary embodiment, the locking lug is configured to move forward on the retaining fin until the end of the retaining fin abuts against the folded portion of the locking lug. This prevents movement of both locking buttons. This limits the lifting of the second locking button to prevent it from being released from the yoke of the wiper arm or from breaking the flexible tab supporting the second locking button.
[0018] In the rest position, the second locking button can rest on the first locking button.
[0019] The first adapter can assemble the wiper blade to a first type of wiper arm, and the locking lug of the first locking button is configured to lock the assembly of the first adapter and the yoke of the first type of wiper arm.
[0020] Another subject of the invention is a wiper device comprising a wiper arm and a wiper blade, characterized in that it comprises a connecting device as described above for connecting the wiper blade to the end of the wiper arm. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical direction Z and the transverse direction X are perpendicular to the longitudinal direction Y and to each other.
[0046] The "front" of the connecting device refers to the head side of the first adapter and the second adapter, while the rear refers to the locking tongue side of the first adapter.
[0047] The terms "upper" and "top" refer to the side of the first adapter to which the second adapter is mounted, while the terms "lower" and "bottom" refer to the opposite side.
[0048] The terms "clip / release", "clip-on fastening / unfastening" and "snap-on fastening / unfastening" are understood to mean a removable assembly produced by elastic deformation of one element in or on another element.
[0049] Figure 1 and Figure 2 A wiper device 1 is shown, comprising a wiper arm 100 for connection to a motorized wiper mechanism of a vehicle and having a yoke 101 at the end thereof, which is connected via a connection device 2 to a wiper blade 300 for cleaning a glass-framed surface of the vehicle, such as a windscreen.
[0050] The wiper device 1 is called "vertical locking" because the connecting device 2 is inserted into the yoke 101 of the arm by a translation movement in the longitudinal direction Y and is locked in place by a locking button that can be actuated vertically relative to the plane of the upper wall of the yoke 101.
[0051] like Figures 3 to 7 As can be clearly seen in FIG, the connecting device 2 has a first adapter 3 and a second adapter 4 , the second adapter 4 being configured to be mounted on the first adapter 3 .
[0052] The connecting device 2 makes it possible, on the one hand, to lock the arm 100 thereto and, on the other hand, to assemble the connector 301 of the wiper blade 300 thereto in an articulated manner.
[0053] The first adapter 3 has a body 5 which extends substantially in the longitudinal direction Y and which (in the plane (X, Z)) has a U-shaped cross section ( Figure 6 ).
[0054] In order to connect the first adapter 3 to the wiper blade 300, the body 5 of the first adapter 3 has a connector housing 6 configured to mate with a connector 301 of the wiper blade 300. The connector 301 is an element of the wiper blade 300 that extends over the wiper rubber body 302 ( Figure 1 ).
[0055] The rotation between the first adapter 3 and the connector 301 is performed around a rotation axis parallel to the transverse direction X. Figure 6 and Figure 7 In an exemplary embodiment as can be seen in FIG, the first adapter 3 includes on one side a cylindrical post 7 configured to mate with a circular aperture of the connector 301 and on the other side a hole 8 configured to mate with the cylindrical post of the connector 301, the cylindrical post 7 and hole 8 of the first adapter 3 being formed in parallel and opposite walls of the connector housing 6.
[0056] The body 5 of the first adapter 3 extends at one of its longitudinal ends to terminate in a head 9 and at the other end to terminate in two flexible locking tongues 10 a , 10 b , with the connector housing 6 interposed between them.
[0057] The head 9 of the first adapter 3 has dimensions in the directions X, Y, Z that are greater than the body 5 of the first adapter and correspond to the dimensions of the yoke 101 .
[0058] Each locking tongue 10a, 10b has a lateral locking portion 11 configured to cooperate with a lateral wall of the yoke 101 of the arm 100, and the locking tongues 10a, 10b can be elastically deformed closer to each other to allow the first adapter 3 to be installed in the yoke 101.
[0059] The first adapter 3 further comprises a flexible tab 12 above the upper wall of the body 5, which extends away from the head 9 into a rear opening 13 in the body 5 of the first adapter 3. The flexible tab 12 supports a first locking button 14 at its end. The first locking button 14 is also located above the rear opening 13 ( Figure 7 ).
[0060] The first locking button 14 has a locking lug 15 at the front end ( Figure 6 The lower surface of the locking lug 15 may be flat. The length of the locking lug 15 may be shorter than the width of the first locking button 14.
[0061] The first adapter 3 makes it possible to assemble a wiper blade 300 to a first type of wiper arm, in particular when used together with one or more additional modules, the first locking button 14 being configured to lock the assembly of the first adapter 3 with the yoke 201 of the arm.
[0062] Figures 11 to 13 An example of an assembly for a first type of wiper arm 200 is shown.
[0063] In this example, a first type of wiper arm 200 comprises a yoke 201 at its end having a U-shaped cross section in the plane (X, Z), an opening 202 formed in the upper wall ( Figure 11 ).
[0064] Additional module 400 in the form of a bracket ( Figure 13 ) is configured to be mounted on the first adapter 3 by engaging on a thin portion of a lateral wall of the body 5 of the first adapter 3 ( Figure 12 ) and is thus configured to be inserted between the first adapter 3 and the yoke 201 of the arm 200.
[0065] During installation in the yoke 201 of a first type of wiper arm 200, the user presses the first locking button 14, which retracts to slide in the yoke 201. The first adapter 3, passed over by the additional module 400, is then inserted into the yoke 201 of the wiper arm 200 by a translation movement in the longitudinal direction Y. The locking tongues 10a, 10b are brought closer together by the yoke 201 and slide in the yoke 201.
[0066] When the yoke 201 abuts against the head 9 of the first adapter 3, the lateral locking portions 11 of the locking tongues 10a, 10b rest against the corresponding lateral walls of the yoke 201, and the first locking button 14 is engaged in the corresponding opening 202 in the yoke 210 by elastic snap fastening, and the locking lug 15 of the first adapter 3 forms a stop in the vertical direction, thereby locking the assembly of the first adapter 3 and the yoke 201 of the first type of wiper arm 200 ( Figure 11 ).
[0067] In order to remove the first adapter 3 , the user presses the first locking button 14 , thereby making it possible to disengage the first adapter 3 from the yoke 201 .
[0068] The first adapter 3 can also assemble the wiper blade 300 to a second type of wiper arm 100 (such as a wiper arm 100) when it is used together with the second adapter 4. Figure 1 and Figure 2 ).
[0069] The second type of wiper arm 100 comprises a yoke 101 at its end with a U-shaped section in the plane (X, Z), an opening 102 formed in the upper wall and two lateral notches 103 formed in the respective lateral walls of the yoke 101 .
[0070] The second adapter 4 is configured to be mounted on the first adapter 3 and thus to be interposed between the first adapter 3 and the yoke 101 of the arm 100 in order to be able to assemble the wiper blade 300 to this second type of wiper arm 100 .
[0071] like Figures 3 to 6 As can be clearly seen in FIG, the second adapter 4 has a body 16 with a U-shaped cross section in the plane (X, Z) and with two side wings 17. The side wings 17 engage on the lateral walls of the body 5 of the first adapter 3 in thin sections 18 of the lateral walls of the first adapter 3 ( Figure 6 ).
[0072] The body 16 of the second adapter 4 extends at one of its longitudinal ends to terminate in a head 19 and at the other end to terminate in a tail 31 , the head 19 likewise extending at the front to terminate in a strip 20 and on either side of the head 19 to terminate in two wings 21 a, 21 b.
[0073] The head 19 has a shape complementary to the recess 22 formed in the first adapter 3 and is, for example, in the form of a parallelepiped.
[0074] The head 19 of the second adapter 4 forms a stop for mounting the connecting device 2 in the yoke 101 of the wiper arm 100 by a translational movement in the longitudinal direction Y.
[0075] The strap 20 extends downwardly so as to be insertable into a front opening 23 in the first adapter 3 located behind the head 9 so as to be received in the head 9 of the first adapter 3. The strap 20 has a dome shape complementary to a circular reinforcement formed below the upper wall of the head 9 so as to be pivotable about the reinforcement when the second adapter 4 is mounted on the first adapter 3, as will be seen below.
[0076] Each wing 21a, 21b extends rearwardly and terminates in a lateral locking portion 24 bearing a resilient finger 25. The lateral locking portion 24 is configured to cooperate with a corresponding lateral notch 103 in the yoke 101 in order to clamp the second adapter 4 to the yoke 101 of the arm 100 ( Figure 2 ).
[0077] The second adapter 4 further comprises a flexible tab 26 above the upper wall of the body 16, which extends the body 16 away from the head 19 and which extends into an opening 27 in the body 16 ( Figure 5 ). The flexible tab 26 supports a second locking button 28 at its end.
[0078] The second locking button 28 is configured to lock the assembly of the second adapter 4 and the yoke 101 of the wiper arm 100 .
[0079] The second locking button 28 has a locking lug 29 at the front end. In the assembled position, the locking lug 29 forms a stop for the wiper arm 100 in the vertical direction ( Figure 2 ).
[0080] The lower surface of the locking lug 29 may be flat. The length of the locking lug 29 may be shorter than the width of the second locking button 28.
[0081] The flexible tabs 26 of the second adapter 4 also support retention fins 30 .
[0082] The retaining fin 30 is arranged below the second locking button 28. The retaining fin extends below the locking lug 15 of the first locking button 14 when the connection device 2 is in the assembled state.
[0083] The retaining fin 30 is, for example, plate-shaped, particularly rectangular. The shape of the retaining fin 30 may be complementary to the lower face of the locking lug 15. The retaining fin 30 extends from the end of the flexible tab 26, with its length extending in a transverse direction X parallel to the axis of rotation of the first adapter 3. Advantageously, the length of the retaining fin 30 in the transverse direction X is the same as the length of the second locking button 28 in order to optimize the contact length within a small space.
[0084] The retaining fin 30, the end of the flexible tab 26 and the lower wall of the second locking button 28 form a retaining groove with a U-shaped longitudinal section ( Figure 4 ).
[0085] When mounting the second adapter 4 on the first adapter 3, first insert the belt 20 of the second adapter 4 into the front opening 23 in the first adapter 3 ( Figure 8A , arrow F1).
[0086] The strip 20 is then received in the head 9 of the first adapter 3 against a reinforcement having a complementary shape formed below the upper wall of the head 9 ( Figure 8B Then the tail portion 31 of the second adapter 4 is pushed against the first adapter 3 so that the first adapter 3 pivots around the head portion 19 of the second adapter 3 ( Figure 8B , arrow F2). The flanks 17 of the second adapter 4 engage in the thin sections 18 of the lateral walls of the first adapter 3. The locking button 14 of the first adapter 3 passes through the opening 27 in the second adapter 4.
[0087] The flexible tab 26 causes the second locking button 28 to rise and the retaining fin 30 is blocked by the locking lug 15 ( Figure 8C Then press the second lock button 28 ( Figure 8C , arrow F3) until the retaining fin 30 is engaged under the locking lug 15 by snap-fit fastening ( Figure 8D ).
[0088] When assembled ( Figure 3 ), the connecting device 2 has an enlarged head, two wings 21a, 21b and a separate locking button raised relative to the first adapter 3. The second adapter 4 leaves the locking tongues 10a, 10b in a free state.
[0089] When the connection device 2 is installed in the yoke 101 of the arm 100 by means of a translation movement, the user places the lateral locking portions 24 of the lateral wings 21a, 21b in the lateral recesses 103 in the yoke 101, tilts the connection device 2 so as to place the locking tongues 10, 10b under the arm 100 ( Figure 9A ). Next, the user pivots the connecting device 2 so as to insert the locking tongues 10a, 10b into the yoke 101 ( Figure 9B ), thereby clamping the second locking button 28 into the yoke 101 ( Figure 9C ).
[0090] When assembled ( Figure 2 ), the lateral locking portions 24 of the wings 21a, 21b engage in the lateral recesses 103 in the yoke 101 of the arm 100, the lateral locking portions 11 of the locking tongues 10a, 10b engage against the corresponding lateral walls of the yoke 201, and the second locking button 28 engages in the corresponding opening 102 in the yoke 101 by an elastic snap-on fastening so as to lock the components of the connecting device 2 to the arm 100.
[0091] In order to remove the connecting device 2 , the user presses the second locking button 28 , thereby making it possible to disconnect the connecting device 2 from the yoke 101 .
[0092] In a static position (such as Figure 5 ), that is, when the second locking button 28 is not exerted with a pulling force, the locking lug 15 of the first locking button 14 is positioned in the retaining groove to be located at a certain distance from the retaining fin 30. The second locking button 28, in particular the rear end, can rest on the first locking button 14.
[0093] For example, when the wiper blade 300 is attached to the windshield, the user pulls the wiper arm 100, and when the second locking button 28 is pulled upward ( Figure 10A , arrow F4), the second locking button 28 rises and the retaining fin 30 engages with the locking lug 15 of the first locking button 14 of the first adapter 3 ( Figure 4 、 Figure 10A and Figure 10B ), which causes the first locking button 14 to move together with the second locking button 28 (arrows F4, F5, Figure 10C 、 Figure 10D The term “engage” is understood to mean bringing the retaining fin 30 into bearing contact with the locking lug 15 , thereby engaging the movement of the two locking buttons 14 , 28 .
[0094] When the second locking button 28 is engaged with the first locking button 14, the strength of the second flexible tab 26 supporting the second locking button 28 is reinforced by the strength of the flexible tab 12 supporting the first locking button 14. Thus, the second adapter 4 takes advantage of the additional rigidity provided by the flexible tab 12 of the first adapter 3. This takes advantage of the stackable adapters 3, 4 of the connecting device 2 and of the fact that the first locking button 14 of the first adapter 3 has a locking lug 15 for locking the first type of wiper arm 200 in order to increase the rigidity of the second locking button 28.
[0095] When the retaining lug 15 of the first locking button 14 comes into contact with the retaining fin 30, the end of the retaining fin 30 is positioned between the locking lug 15 and the body of the first locking button 14 at a distance from the folded portion of the locking lug 15 formed below the locking lug 15 ( Figure 10B The distance j between the end of the retaining fin 30 of the second adapter 4 and the folded portion of the locking lug 15 of the first adapter 3 is, for example, between 0.1 mm and 3 mm ( Figure 10B ).
[0096] Then, when the locking button 14, 28 is raised, the locking lug 15 can move forward on the retaining fin 30 ( Figure 10C ). The greater the pulling force, the more the first locking button 14 moves forward on the retaining fin 30, and the more the vertical retention can be improved.
[0097] If the pulling force is continued to be applied, the locking lug 15 can move forward on the retaining fin 30 until the retaining fin 30 abuts in the folded portion of the locking lug 15, thereby eliminating the initial gap j ( Figure 10D ). This prevents the two locking buttons 14, 28 from moving. It is no longer possible to pull the second locking button 28 further. This limits the lifting of the second locking button 28 in order to avoid the second locking button 28 being released from the yoke 101 of the wiper arm 100 or the flexible tab 26 supporting the second locking button 28 being broken.
[0098] Thus, despite the second adapter 4 being of a very thin and flexible design and therefore being located within the small available space in the connection device 2 , the stiffness and the vertical retention when faced with tensile forces can be improved.
