Connecting device for a pantograph wiper arm.

摘要

A wiper system of the pantograph arm type comprises an actuating arm 1 at the front end of which a wiper blade (not shown) is rotatably attached by means of a first element 3, and a control arm 2, the front end of which is rotatably attached to the element 3 by means of a second element 6. The second element 6 is made of a flexible material and its central portion (6 sec ) has a substantially circular cross-section which is substantially smaller than the cross-section at its two extremities and acts not only as a pivot but also as a ball joint between the control arm 2 and element 3 so that the control arm may take up different angular positions with respect to the element 3 in all directions.
