Problems solved by technology

[0010] However, it can be seen that the different devices proposed so far are either too complicated to implement, or over time, the exact position of the ball-and-socket joint on the crank is not permanent and reliable enough

Embodiment Construction

[0024] To describe the invention, in a non-limiting manner, as follows Figure 2a Marks V, L, and T shown in indicate vertical, longitudinal, and transverse directions.

[0025] In the following description, the same, similar and similar parts are denoted by the same numerals.

[0026] figure 1 A conventional wiper mechanism 20 for a windshield of a motor vehicle (not shown in the figure) is shown in FIG. The wiper brushes are movable in rotation about an approximately vertical axis A. The wiper mechanism 20 comprises a linkage system consisting of a transmission rod 24 and a crank 26 which connect the wiper brush 22 with a mechanical reduction gear 28 which ensures the drive of the wiper mechanism 20 .

[0027] Such as Figures 2a to 2c As shown, each crank 26 is known to have a generally flat body 30 extending longitudinally in a horizontal plane and having a first end 30 a hinged about the vertical axis of rotation of the associated wiper brush 22 .

Abstract

The invention concerns a method for adjusting the angular travel of a motor vehicle wiper mechanism, comprising a connecting rod and a crank, wherein the crank includes a body which extends longitudinally in a substantially horizontal plane, which is articulated at one first end about a vertical axis (A), and which is articulated at a second end to the connecting rod, comprising a step which consists in adjusting the angular travel by modifying the distance between the first and the second articulated ends of the crank. The invention is characterized in that the adjusting step consists in modifying the length of a longitudinal section of the body of the crank.

Description

technical field [0001] The invention proposes a method for adjusting the angular travel of a motor vehicle wiper mechanism, said type of wiper mechanism comprising a transmission rod and a crank, in said type of wiper mechanism, the crank has a main body, said main body Extended longitudinally in a generally horizontal plane, and its first end is hinged around a vertical axis, and its second end is hinged on the transmission rod. The distance to adjust the angular travel steps. Background technique [0002] This type of transmission rod is connected to a crank, for example, in some driving devices, in which an electric motor, possibly connected to a reducer, wipes back and forth to drive at least one wiper, which is connected to the The vehicle is connected to a drive shaft that is rotatably mounted. [0003] By means of a drive handle and crank mechanism, for example, the continuous rotational movement of the output shaft of the drive motor can be converted into an altern...
