    "Hinged linkage device from a wiper blade to a wiper arm"
    Field of the invention
    The present invention relates to a device for hingedly connecting a wiper blade to a wiper arm having a connecting member attached to the wiper blade, and a plug-in connection member at the end. the wiper arm, which attaches to the wiper arm and is pivotally mounted about a pivot axis on the connecting member.
    State of the art
    According to WO 02/34591, a windscreen wiper is known whose wiper blade is hingedly connected to the wiper arm by means of a device. The wiper blade has a rubber profile with a wiper lip and a head bar. Side grooves of the head bar receive two resilient rails serving as support members. These rails are pre-bent so that the rubber profile with its wiper lip is applied under the effect of the application force exerted by the wiper arm with the desired pressure against the windshield and Wiper movement case, follow the bending of the windshield. This connecting device for connecting the wiper blade to the wiper arm has a connecting element installed with claws on the elastic rails and pivotally mounted on a connecting element. This is removably connected to the wiper arm. For this purpose, the wiper arm has an end of rectangular cross-section which slides in a connection channel of the connecting element until an engagement element clings to an elastically deformable wall of the connecting channel. plugs into a cavity of the wiper arm. If the snap-in element does not snag or only insufficiently into the wiper arm cavity, the wiper blade may detach from the arm during operation.
    Description and advantages of the invention
    The object of the present invention is to remedy these drawbacks and to this end relates to an articulated connection device for connecting a wiper blade to a wiper arm of the type defined above, characterized in that the connecting member has a locking pin which comes into a cavity of the wiper arm when the wiper blade is in the operating position.
    The lock pin prevents errors in mounting the wiper blade because the wiper blade can only be tilted into the operating position if the lock pin can engage the wiper arm cavity. -ice cream. But in this position, we are sure that the connecting element is properly attached to the end of the wiper arm. In addition, the wiper blade is securely secured by the lock pin in the operating position, in the longitudinal direction of the wiper arm. The cavity of the wiper arm may be constituted by a notch of a large side of the wiper arm, a hole or a corresponding cavity.
    Advantageously, the connecting element is partially covered on the top by a cover so that the bearing elements for the link articulated to the connecting element out of the cover. But it is also possible to provide bearing elements on the cover, elements which are fixed on the connecting element. If in a device there is provided a cover, according to a development of the invention, it is advantageous to provide the locking lug on the cover which can easily be made of plastic as an injected part.
    According to another development of the invention, the connecting element is connected to the wiper arm by a plug connection and a reception profile whose section corresponds to the section of the profile at the end of the arm of the wiper arm. The windshield wiper has a snap-on tongue with the snap-in member into the mounting position in a snap-in hole of the wiper arm. It is advantageous for the wiper arm to have a rectangular section profile whose long sides are at an angle to the windscreen so that the longer sides of the wiper arm increase the application force. windshield wiper arm depending on the wind speed. This effect can be increased if the connecting element has an upper side inclined at a similar angle.
    drawings
    The present invention will be described below in more detail with the aid of exemplary embodiments shown in the accompanying drawings in which: - Figure 1 shows a partial exploded view of a windscreen wiper blade and a wiper arm; FIG. 2 is a perspective view of a connecting element carried on two elastic rails; FIG. 3 is a perspective view of a wiper blade and a wiper blade; wiper arm just before moving to the operating position, and - Figure 4 is a perspective view corresponding to Figure 3 of a windscreen wiper blade in the incorrectly installed position.
    Description of an embodiment
    Figure 1 shows an end of a wiper arm 10 in the form of wiper rod having a substantially rectangular section 12. The long sides of the rectangle are at an angle with respect to the windshield of a vehicle which gives a deflector effect to the wiper arm 10. On the end of the wiper arm 10, we slide a connecting element 38 having a reception profile corresponding to the section of the profile 12. At the receiving profile, there is an interlocking tab 40 whose unseen clipping element clings to the mounting in a Closing port 14 at the end of the wiper arm 10. The upper side of the connecting element 38 is inclined at the inclination of the wiper arm 10 to promote the deflector effect.
    The connecting element 38 is pivotally connected about a pivot axis 28 to the connecting element 22. The latter is fixed by claws 24 to the elastic rails 20. The rails serve as a support element of the Wiper blade 18. In place of two elastic rails 20, it is also possible to provide a single elastic rail housed in a central longitudinal channel of a wiper blade. The connecting element 22 comprises a bearing pin 26 coaxial with the pivot axis 28 with which non-visible bearing elements of the connecting element 38 cooperate.
    A cover 30 partially covers the top of the connecting element 22 so that the bearing studs 26 leave the cover 30. On the front face, the cover 30 has a connection profile 32 providing a smooth transition between the cover 30 and a deflector 36 carried by the rails 20.
    The cover 30 has a locking pin 34 at its end facing the wiper arm 10. In the operating position of the windscreen wiper blade 18, it enters a cavity 16 of the wiper arm 10 This is possible only if previously the clipping element of the snap-in spring 16 has been hooked correctly into the snap-in hole 14. FIG. operating mode while Figure 4 highlights the locking function of the locking pin 34 if due to improper mounting, the clipping member of the latching tongue 40 is not yet hooked.
