Abstract:
1. A crank belonging to a linkage for transmitting the movement of a wiping mechanism of a motor vehicle, the crank comprising: a body that extends in a generally horizontal plane, a first end which is linked in rotation to a wiping arm that revolves around a generally vertical axis, and a second end which is articulated to a connecting rod of the linkage, wherein the body comprises a segment that can be deformed in a permanent fashion in order to adjust the distance between the first and second ends of the crank, and an oblong hole with a generally longitudinal orientation which divides the segment into two deformable longitudinal branches, globally symmetrical in relation to a central longitudinal axis of the segment, wherein an area of a transverse cross-section of each branch is globally constant throughout a length of the longitudinal branches between concave angles of the hole, and wherein the area of the transverse cross-section of each branch is smaller at the concave angles than between the concave angles of the oblong hole, wherein the oblong hole has a quadrilateral shape comprising a large diagonal and a small diagonal which are perpendicular to each other, the large diagonal matching a main axis of symmetry of the segment and intersecting the small diagonal at a midpoint of the small diagonal.
