The wiper blade adapter has a locking means functioning as a wiper blade adapter anti-lost safety device connected to the wiper arm adapter, in the event of a failure of the wiper blade adapter. fixing means.
    Description and advantages of the invention
    The present invention relates to a windscreen wiper device of the type defined above, characterized in that considered from the pivot axis a fastening means is in front of the locking means.
    In other words, the invention relates to a wiper device comprising a wiper arm adapter with a wiper arm driven around a pivot axis and which comprises an adapter windscreen wiper blade with at least one detachable fastening means for releasably attaching the wiper blade adapter to the wiper arm adapter and having the adapter Wiper Blade has a locking mechanism that functions as an anti-loss safety of the ice-wiper arm adapter connected to the wiper arm adapter in the event of a failure. at least one fastening means.
    According to the invention, considered from the axis of pivoting, the fixing means is in front of the locking means. This allows a very compact design of the wiper arm adapter. In addition, there is thus a particularly strong operating safety. A "wiper arm adapter" in the present context includes an adapter that has a contact area for the wiper arm and is captively connected to the wiper arm by developing a wiper arm adapter. coupling area of the wiper arm for coupling and / or bringing it into contact with the wiper blade adapter.
    Preferably, the wiper arm adapter is in one piece with a wiper rod of the wiper arm. The term "one-part" should be considered in this case as being dependent on the material, such as, for example, by a welding process and / or a gluing process. In a particularly advantageous manner, it is a casting process and / or an injection process with one or more components. The wiper blade adapter is, in the present context, in particular an adapter which has a contact area for a so-so-so-ice broom component and which is captively connected to this broom component. wiper system by means of a coupling area of the wiper blade component for coupling and / or contact with the wiper arm adapter.
    Advantageously, the wiper blade adapter is in several parts. The wiper arm comprises in particular a wiper rod, a hinge and / or a fastener. The hinge is advantageously mounted, pivotally, on a fastener. The hinge piece is furthermore advantageously loaded by a spring in its mounting on the fastener. The fastener in the assembled state is connected to a drive shaft. The drive shaft is advantageously driven by a motor in a pendulum motion. The hinge piece or more simply the hinge is advantageously connected to the wiper rod and / or is formed in one piece. A plane perpendicular to the longitudinal direction of the wiper arm and which moves from the fastener to the wiper blade adapter is a plane which first cuts at least one fixing means and then at least one locking means.

Advantageously, the fastening means is capable of being deflected by the deformation of the material, by the deformation of the joint and / or particularly advantageously by a deformation of material. At least one detachably fixed attachment means, the ice-wiper arm adapter to the wiper arm adapter in the longitudinal direction of the wiper arm. Advantageously, the wiper arm adapter has at least one attachment means for attaching the wiper blade adapter by a shape connection. In the event of a failure of a fastening means, the locking means preferably provides a form connection between the wiper arm adapter and the wiper blade adapter, which link operates in the longitudinal direction of the wiper arm.
    According to another advantageous characteristic, the wiper arm adapter and the wiper blade adapter, in case of failure of at least one fastening means, have play with respect to the other, so that the fault can be displayed for the user such as the driver. Failure in the present context means, in particular, rupture, accidental detachment and / or other undesired deviation from an operating configuration. The term "intended" refers to a means that is very specifically designed by a certain function. The fact that an object performs a certain function always means that this object performs this function in at least one application and / or operating state.
    According to another development of the invention, the wiper blade adapter comprises a connecting element and a coupling element; the connecting element is integrally connected to the wiper blade and the disassembled coupling element pivots on the connecting element.

In particular, the coupling element is provided for releasably coupling the wiper arm adapter. Preferably, the coupling element attaches to the connecting element at the time of assembly.
    According to another characteristic, at least one fastening means is provided on a side wall of the coupling element, which gives a particularly compact wiper blade adapter. The side wall advantageously extends, at least essentially, perpendicular to the wiping direction and forms, in a particularly preferred manner, at least in zones, an angle substantially equal to 45 ° with the direction the wind. In a particularly preferred manner, the side wall comprises a deflecting surface. Advantageously, the side wall is bent. The expression "at least essentially" means in this context that the difference must be less than 20%, preferably less than 5% and particularly preferably less than 1% or, in the case of an angular indication, the angular difference must be less than 30 ° and preferably less than 10 °, and even more preferably equal to 1 °.
    In addition, at least one attachment means may be deflected about a longitudinal axis that is at least substantially parallel to the main longitudinal extension direction of the wiper arm adapter. This allows a very simple and intuitive movement of at least one attachment means by a targeted user. The expression "principal longitudinal extension direction" of an object designates in particular a direction parallel to the longest edge of the smallest geometrical parallelepiped enveloping just yet the object
    According to another characteristic, the wiper arm adapter comprises at least one locking recess open in the wiping direction and receiving at least one fastening means. This allows for a particularly secure form connection for attaching the wiper blade adapter to the wiper arm adapter. Advantageously, at least one fixing recess and at least one fixing means are complementary in their shape.
    According to another characteristic, the wiper blade adapter comprises at least one deflection means for deflecting at least one automatic fixing means for at least one pivoting movement of the coupling element relative to the element. link. This allows a particularly great user comfort and simple disassembly. The pivoting phase is in particular around a pivot axis which is at least essentially parallel to a wiping plane and perpendicular to the longitudinal direction of the wiper arm.
    According to another characteristic, at least one deflection means is formed on at least one fastening means, which makes it possible to produce a fastening means which is particularly safe in its operation and which can be deviated without risk. Advantageously, the deflection means is made in one piece with the coupling element of the wiper blade adapter.
    According to another characteristic, the deflection means attaches to the connecting element at least during the pivoting maneuver thus exerting a traction force on the deflection means. This allows for a very comfortable disassembly of the wiper arm adapter relative to the wiper blade adapter. Advantageously, the wiper device carries the wiper arm.

Description of exemplary embodiments
    Figure 1 shows a wiper device having a wiper arm 16a and a wiper blade 26a in side view. The wiper blade 26a is a flat wiper blade. The wiper blade 26a serves to clean a vehicle window 40a. The wiper arm 16a has a wiper arm adapter 10a. The wiper arm 16a has a wiper rod 42a. The wiper arm 16a has a hinge 44a. The hinge 44a is crimped onto the wiper rod 42a. The wiper arm 16a has a fastener 46a. The fastener 46a is hingedly connected to the hinge 44a. A non-detailed spring urges the fastener 46a relative to the hinge 44a at least during operation.
    The wiper arm 16a attaches to a drive shaft 48a. For this purpose, the fixing piece 46a is integrally connected in rotation in a coupled manner to the drive shaft 48a. The drive shaft 48a is made to rotate about a pivot axis 14a according to the non-detailed oscillating motion of the motor. The wiper arm adapter 10a is thus installed on the wiper arm 16a driven around the pivot axis 14a. The wiper arm adapter 10a is in one piece with the wiper rod 42a. In this context it is also possible to crimp the wiper arm adapter 10a to the wiper rod 42a.
    The wiper blade 26a has a first deflector element 50a. The first deflector 50a deflects the traffic wind and generates a thrust applying the wiper blade device against the window 40a of the vehicle. The first baffle member 50a extends substantially over one-half of the total longitudinal extent of the wiper blade 26a. The wiper blade 26a has a second deflector element 52a. The wiper blade 26 may alternatively comprise a number of deflector elements other than two. The second deflector element 52a is distinct from the first deflector element 50a. The first deflector element 50a and the second deflector element 52a are plane symmetrical. The second deflector element 52a makes it possible to deflect the driving wind and to generate a thrust force exerted on the wiper blade 26a in the direction of the window / windshield 40a. The second deflector member 52a extends substantially over one-half of the total longitudinal extent of the wiper blade 26a. The baffle members 50a, 52a each have a concave wind passage surface. The deflector elements 50a, 52a are at least partly made of rubber and / or at least partly of plastics material.
    The wiper blade 26a further comprises a wiper blade 54a. The opposite free ends of the wiper blade 54a carry end segments 56a, 58a. The wiper blade 26a has two end caps 60a, 62a. The first end cap 60a describes an outer circular arc during wiping. The second end cap 62a describes an inner circular arc during the wiping motion. The first end cap 60a is further away from the fastener 46a than the second end cap 62a. The end segments 56a, 58a of the wiper blade 54a receive the end caps 60a, 62a. The end caps 60a, 62a terminate the wiper blade 26a in its longitudinal direction.
    The longitudinal direction is at least substantially parallel to the main longitudinal extension direction 32a of the wiper arm adapter 10a. The wiper blade 54a has a wiper lip 64a for wiping the window 40a. The wiper lip 64a is made of a rubbery material.
    The wiper device includes a wiper blade adapter 12a. The wiper blade adapter 12a is intended to be coupled to the wiper arm adapter 10a. The wiper blade adapter 12a and the wiper arm adapter 10a are shown in greater detail in Figure 2 prior to mounting. The other components are not presented for reasons of readability of the drawing. The wiper blade adapter 12a is in several parts. The wiper blade adapter 12a has a connecting member 22a. The wiper blade adapter 12a has a coupling member 24a. The connecting element 22a is integrally connected to the wiper blade 26a. The coupling element 24a is pivotally mounted on the connecting element 22a. The connecting element 22a comprises a pivot bearing 66a. The pivot bearing 66a serves to pivotally receive the coupling member 24a. The wiper blade adapter 12a forms a receiving channel 84a for receiving the wiper arm adapter 10a (FIG. 3). The wiper blade adapter 12a has a deflectable fastening means 18a. The fixing means 18a can be deflected elastically against a spring force. The fastening means 18a is deflected by the deformation of its material. The fastening means 18a is provided on a side wall 28a of the coupling element 24a. In the region of the fastener 18a, an axis perpendicular to the wind stop surface 68a of the side wall 28a makes with the wiping direction 36a an angle which is at least substantially equal to 45 °.
    The fixing means 18a can be deflected around a longitudinal axis 30a. The longitudinal axis 30a is at least substantially parallel to the main longitudinal extension direction 32a of the wiper arm adapter 10a. The fastening means 18a forms a service surface 70a. The fastening means 18a can be deflected by the user through the service surface 70a. The user pushes the service surface 70a toward the window 40a to deflect the fastening means 18a.
    Figure 4 shows the attachment means 18a in its cooperation with the wiper arm adapter 10a. To simplify the representation, only the wiper arm adapter 10a and the coupling member 24a of the wiper blade adapter 12a are shown. The fastening means 18a is provided to allow removable attachment of the wiper blade adapter 12a to the wiper arm adapter 10a. The wiper arm adapter 10a has a fixing recess 34a. The fixing recess 34a is open in the wiping direction 36a. The fixing recess 34a is on a longitudinal side of the wiper arm adapter 10a. The fixing recess 34a receives the fixing means 18a. The fastening means 18a provides, in the fastening recess 34a, a connection by the cooperating shape in the main longitudinal extension direction 32a; this shape connection connects the wiper arm adapter 10a and the wiper blade adapter 12a. The fastening means 18a form a latching nose 72a. The hooking nose 72a has a hooking surface 74a inclined relative to the main longitudinal extension direction 32a. The wiper arm adapter 10a has a locking recess 76a. The locking recess 76a is in the end region of the wiper arm adapter 10a. The end zone of the wiper arm adapter 10a is hook-shaped. The width 78a of the wiper arm adapter 10a at its outer end 82a is smaller than the width 80a of the wiper arm adapter 10a beyond the end zone. The outer end 82a in the installed state is on the wiper blade adapter 12a in the main longitudinal extension direction 32a. The locking recess 76a is open in the wiping direction 36a. The locking recess 76a is on the longitudinal side of the wiper arm adapter 10a. Specifically, the locking recess 76a is on the same longitudinal side of the wiper arm adapter 10a as the fixing recess 34a.
    Figure 5 shows the wiper arm adapter 10a and the wiper blade adapter 12a in the mounted state. The coupling element 24a is pivotally mounted on the connecting element 22a. The coupling element 24a can pivot in one direction and the other with respect to the connecting element 22a between a release position and an operating position. The maximum swing range corresponds to an angle of approximately 13 °. The wiper blade adapter 12a has a locking means 20a. The locking means 20a constitutes an anti-loss security of the wiper blade adapter 12a on the wiper arm adapter 10a in the event of failure of the attachment means 18a. The locking means 20a is made in one piece with the connecting element 22a. The locking means 20a is of parallelepipedal shape. The locking means 20a forms a stop surface 100a perpendicular to the main longitudinal extension direction 32a. The fastening means 18a considered from the pivot axis 14a is in front of the locking means 20a. In other words, the fastening means 18a is closer to the inner circular arc than the locking means 20a. The coupling element 24a forms a receiving bowl 102a. Receiving cuvette 102a receives the outer end 82a of the wiper arm adapter 10a. The wiper arm adapter 10a is completely surrounded at least in one plane by the receptacle bowl 102a. The locking recess 76a receives the locking means 20a. In Figure 5, the wiper device is in the release position. The longitudinal main extension direction 32a of the wiper arm adapter 10a forms with the main longitudinal extension direction of the wiper blade adapter 12a, an angle greater than 11 °. The wiper arm adapter 10a is thus out of engagement with the fastening means 20a. In case of actuation of the fastening means 18a, the wiper arm adapter 10a is released from the wiper blade adapter 12a and is removed. For mounting, the windscreen wiper must be in the release position. For mounting, the wiper arm adapter 10a is driven into the receiving channel 84a. The fixing means 18a remains without contact with the end 82a of the wiper arm adapter 10a. Due to the reduced width 78a of the end 82a of the wiper arm adapter 10a, the attachment means 18a will be deflected only in an area of the wiper arm adapter 10a which will be retracted beyond the locking recess 76a. There will be a clipping noise only during the attachment of the fastening means 18a in the fixing recess 34a.
    After hooking of the fixing means 18a in the fixing recess 34a, the wiper blade adapter 12a is tilted (FIG. 6) with respect to the wiper arm adapter 10a in position Operating. The coupling element 24a is not shown in FIG. 6 so as not to overload it. The longitudinal main extension direction 32a of the wiper arm adapter 10a forms an angle of the order of 0 ° with the main longitudinal extension direction of the wiper blade adapter 12a. in operating position. The locking means 20a thus enters the locking recess 76a. In the event of a failure of the fastening means 18a in the fixing recess 76a, the locking means 20a provides a shape connection between the wiper arm adapter 10a and the wiper blade adapter. ice 12a, this shape bond acting in the longitudinal main extension direction 32a. The failure of the fastening means 18a could, for example, be tearing the fastening means 18a. In this case, the wiper blade adapter 12a can slide relative to the wiper arm adapter 10a in the main longitudinal extension direction 32a until the locking means 20a is supported with one side of the wiper arm adapter 10a delimiting the safety recess 76a. The wiper arm adapter 10a and the wiper blade adapter 12a have play in the event of failure of the fastening means 18a. The wiper arm adapter 10a can thus rotate in different directions relative to the wiper blade adapter 12a. The user can detect any defect of the fastening means 18a.
    Figures 7-9 show another embodiment of the invention. The following descriptions and drawings are mainly limited to the differences between the various exemplary embodiments and for the components bearing the same numerical references, reference will be made to the drawings and / or the description of the exemplary embodiment of FIGS. 1 to 6. In order to distinguish the exemplary embodiments, the letter (a) in suffix of the numerical references of the embodiment example of FIGS. 1-6, will be replaced in the embodiment of FIGS. 7-9 by the letter (b).
    Figure 7 shows a wiper arm adapter 10b of a wiper arm 16b corresponding to an alternative embodiment of the windscreen wiper device. The wiper arm adapter 10b is mounted, as in the first embodiment, on a wiper arm 16b driven about a pivot axis. The wiper arm adapter 10b is made in one piece with a wiper rod 42b of the wiper arm 16b. It is also possible in this context to crimp the wiper arm adapter 10b to the wiper rod 42b. The wiper arm adapter 10b has the shape of a flattened rod. The wiper rod 42b also has the shape of a flattened rod. The wiper arm adapter 10b has a locking recess 76b. The locking recess 76b is surrounded at least in one cutting plane completely by the wiper arm adapter 10b. The locking recess 76b, in the wiping direction 36b, is in the middle of the wiper arm adapter 10b. The fixing recess 76b has a rectangular section. The locking recess 76b passes through the upper side 88b of the wiper arm adapter 10b. The safety recess 76b is open in the vertical direction 86b. The locking recess 76b passes through the wiper arm adapter 10b in the vertical direction 86b. The vertical direction 86b is at least substantially perpendicular to a window to be wiped. The wiper arm adapter 10b includes a hooking means 90b. The attachment means 90b has a hooking surface 92b. The hooking surface 92b is inclined relative to the main longitudinal extension direction 32b. The hooking surface 92b is directly adjacent to the locking recess 76b. The hooking surface 92b considered in the main longitudinal extension direction 32b is offset relative to the locking recess 76b. The locking recess 76b passes through the same longitudinal side of the wiper arm adapter 10b as the hooking means 90b.
    As shown in Figures 8 and 9, the wiper device has a wiper blade adapter 12b. The wiper blade adapter 12b has a connecting member 22b. The wiper blade adapter 12b has a coupling member 24b (FIG. 9). The coupling element 24b is pivotally mounted on the connecting element 22b. The connecting element 22b carries a pivot bearing 66b. The pivot bearing 66b pivotally receives the coupling member 24b. The connecting element 22b is integrally connected to a wiper blade not shown here. The wiper blade adapter 12b has a locking means 20b. A locking means 20b provides an anti-loss security of the wiper blade adapter 12b connected to the wiper arm adapter 10b in the event of a failure of the attachment means 18b. The locking means 20b is made in one piece with the connecting element 22b. The locking means 20b terminates in a point by its free end. The locking means 20b has a rectangular section. The locking means 20b forms a stop surface 100b perpendicular to the main longitudinal extension direction 32b.
    As shown in Fig. 9, the wiper blade adapter 12b forms a receiving channel 84b for receiving the wiper arm adapter 10b. The receiving channel 84b is formed in the coupling element 24b. The wiper blade adapter 12b has a deflectable attachment means 18b. The fixing means 18b deforms elastically against a spring force. The fixing means 18b deflects by deformation of the material. The fixing means 18b locally forms a wall 94b of the receiving channel 84b. The fastening means 18b can be deflected around a transverse axis. The transverse axis is parallel to the wiping direction 36b. The fastening means 18b moves from an operating position to a release position. The fastening means 18b can be moved in the direction of the connecting member 22b to arrive in the release position. The fastening means 18b considered from the pivot axis is in front of the locking means 20b. In other words, the fastening means 18b is closer to the inner circular arc than the locking means 20b.
    Figures 10 and 11 show the wiper arm adapter 10b and the wiper blade adapter 12b in the installed state. The coupling element 24b is pivotally mounted around the connecting element 22b. The coupling element 24b can be pivoted in one direction and the other with respect to the connecting element 22b between the release position and the operating position. The maximum swivel range corresponds to an angle of approximately 13 °.
    As shown in FIG. 10, the locking recess 76b receives the locking means 20b. The wiper device is thus in the operating position. The longitudinal main extension direction 32b of the wiper arm adapter 10b forms with the main longitudinal extension direction of the wiper blade adapter 12b in the operating position, an angle of order of 0 °. The locking means 20b thus enters the locking recess 76b. The locking means 20b penetrates up to half into the locking recess 76b. The attachment means 90b is applied against the fastening means 18b. The attachment means 18b provides for the removable attachment of the wiper blade adapter 12b to the wiper arm adapter 10b. The fastening means 18b makes with the attachment means 90b a form connection between the wiper arm adapter 10b and the wiper blade adapter 12b; this shape bond acts in the main longitudinal extension direction 32b. The wiper blade adapter 12b has a disengagement means 38b. The disengaging means 38b deflects the fastening means 18b automatically by a pivotal movement of the coupling member 24b with respect to the connecting member 22b. This pivoting operation drives the wiper device from the operating position to the release position. The pivoting operation is around a pivot axis which is at least substantially parallel to the wiping plane and perpendicular to the longitudinal direction of the wiper arm. The pivot axis is at least essentially parallel to the wiping direction 36b. The disengagement means 38b is made in one piece with the fastening means 18b. The disengagement means 38b is formed on the fixing means 18b. The disengaging means 38b is spaced from the fastening means 18b by an angle which is at least 90 °. Thus, the disengagement means 38b is made in one piece with the head member 24b of the wiper blade adapter 12b.
    The disengagement means 38b clings to the connecting element 22b during the pivoting phase. The disengagement means 38b exerts a tensile force on the fastening element 18b during the pivoting operation. The free end of the disengagement means 38b includes a hook 96b. The connecting element 22b comprises a cross member 98b. The hook 96b during pivoting from the operating position to release position bears against the cross 98b. For continued pivoting, the deflection means 38b remains attached to the spacer 98b and forces the fastening means 18b to deflect in the opposite direction to that of an elastic spring force. In Figure 11, the wiper device is in the release position. The longitudinal main extension direction 32b of the wiper arm adapter 10b forms with the main longitudinal extension direction of the wiper blade adapter 12b, an angle greater than 11 °. The wiper arm adapter 10b is thus outside the intervention of the fixing means 20b. The fixing means 18b is deflected by the deflection means 38b. The wiper arm adapter 10b can then disengage and remove from the wiper blade adapter 12b.
    For mounting, the windscreen wiper must be in the release position. For mounting, the wiper arm adapter 10b is guided in the receiver channel 84b. The fastening means 18b remains out of contact with the attachment means 90b of the wiper arm adapter 10b. After complete introduction of the wiper arm adapter 10b into the receiver channel 84b, the wiper blade adapter 12b is tilted with respect to the wiper arm adapter 10b in its operating position. In the locking recess 76b, the locking means 20b forms in case of failure of the fastening means 18b, a connection by the shape extending in the main longitudinal extension direction 32b, between the arm adapter of 10b wiper and 12b wiper blade adapter. The failure of the fastening means 18b is, for example, its breakage. In this case, the wiper blade adapter 12b may slide relative to the wiper arm adapter 10b in the main longitudinal extension direction 32b until the locking means 20b is supported with one side of the wiper arm adapter 10b, which side delimits the safety recess 76b. The wiper arm adapter 10b and the wiper blade adapter 12b have clearance therebetween in the event of failure of the fastening means 18b. The wiper arm adapter 10b can thus rotate in different directions relative to the wiper blade adapter 12b and the user can thus see that the fastening means 18b is defective.
