Abstract

A connecting device is provided for selectively connecting one of at least two different type wiper arm ends to a wiper blade having a rectangular opening in an upper portion of the blade. The wiper blade has laterally spaced side walls defining the rectangular opening with two pairs of aligned openings in said side walls. The diameter of one pair of aligned openings being different from the diameter of the other pair of aligned openings to receive recessed end portions of two different diameter pins. The connecting device seats in the rectangular opening and has latching means engaging with the recessed end portion of the selected one of the pins fitted in the pair of aligned openings in the side wall to retain the pin latched to the wiper blade. The connecting device has projections engaging with the edge of the rectangular opening in the blade or with a third pin on the blade for retaining the connecting device on the blade.

Dependent claims

A connecting device (10, 20) for selectively connecting a wiper blade to a first and to a second wiper arm, wherein the superstructure (4) of the wiper blade comprises a substantially rectangular opening (7) laterally limited by two walls (4a, 4b), characterized in that:

a. the two wiper arms are respectively provided with a first pivot pin (1) having given dimensions and with a second pivot pin (2) having other dimensions,
b. said lateral walls (4a, 4b) are respectively provided with a first circular opening (6a, 6b) of which the diameter is slightly larger than the diameter (D1) of the first pivot pin (1) and with a second circular opening (5a, 5b) of which the diameter is slightly larger than the diameter (D2) of the second pivot pin (2), the circular openings (6a, 6b;
5a, 5b) which respectively correspond to the first and to the second pivot pin (1, 2) being in alignment, and
c. the connecting device (10, 20) and the two pivot pins (1, 2) are provided with corresponding latching means (16, 26, 1b;
17, 27, 2b), capable of locking one or the other of said pivot pins (1, 2) on the superstructure (4) of the wiper blade.
