Abstract
A pantograph-type windshield wiper system is provided with a unique and novel connector which permits rotatable movement about two transverse axes. In particular, the connector permits a removable connection of a pantograph-type arm to a conventional cross-pin type blade and maintains a low profile relative to the windshield. The connector is assembled with the cross-pin of the blade (which cross-pin provides one rotative axis) and with a depending pin on the arm end (which pin provides the second rotative axis). The depending pin on the arm removably locks the connector on the cross-pin.

A connecting device (4,5,6,19,5,6) for connecting a wiper blade (3,9) to a wiper arm (1), wherein the wiper blade (3,9) is capable of rotating about a first pivot pin (6) attached to the wiper arm (1) and about a second pivot pin (5) attached to the superstructure (3) of the wiper blade (3,9) and extending substantially perpendicularly with respect to the first pivot pin (6) characterized in that:
- the body (4,19) of the device comprises a seat (15,25) for the first pivot pin (6) which has the form of a straight circular cylinder and a seat (14,24) for the second pivot pin (5) which has the form of a T or L-shaped straight cylinder;
- and
- the first pivot pin (6) of the device includes an annular recess (16) capable of cooperating with the second pivot pin (5).
