| 摘要 |
The invention proposes a transmission device of the type including a rotating shaft (14) connected in terms of rotation to the first end (26A) of a crank (26), on the second end (26B) of which there acts a crank pin (50) which is designed to be connected to a driving connecting rod (52) belonging to a movement transmission linkage for the alternating rotational driving of a motor vehicle windscreen wiper, and of the type including a guiding link rod (30), the first end (30A) of which is mounted so that it can turn on a pivot (32), and the second end of which bears the crank pin (50), characterised in that it includes means (36, 42, 44, 48) for causing the position of the axis (Y-Y) of the pivot (32) relative to the axis (X-X) of the rotating shaft (14) to vary, the pivot (32) being mounted eccentric on an actuating shaft (36) with which it is rotationally connected, an actuator (48) being provided for rotationally driving and immobilising the actuating shaft (36). <IMAGE>
