Abstract

The invention relates to a connecting device (10) for the articulate connection of a wiper arm to a wiper blade (12) according to a side-lock principle, comprising a connecting element (36) that is fastened to the wiper arm and that runs laterally in relation to a connection element (24) fastened on the wiper blade (12) and that carries a bearing element (34, 38) forming a pivot bearing with a bearing element (34, 38) on the connection element (24), said pivot bearing running transversely to the longitudinal direction of the wiper blade (12), wherein a locking device (40) secures the bearing elements (34, 38) during pivoting into an operational position in the direction of the pivot axis relative to each other. According to the invention, a coding device (46, 52) is provided between the connecting element (36) and the connection element (24) that allows pivoting of the wiper blade (12) into the operational position only if the wiper blade (12) is intended for operation with the associated wiper arm.

A connecting device (10) for the articulate connection of a wiper arm to a wiper blade (12) according to a side-lock principle, comprising a connecting element (36) that is fastened on the wiper arm and that runs laterally in relation to a connection element (24) fastened on the wiper blade (12) and that carries a bearing element (34, 38) forming a pivot bearing with a bearing element (34, 38) on the connection element (24), said pivot bearing running transversely to a longitudinal direction of the wiper blade (12) and defining a pivot axis, wherein a locking device (40) secures the bearing elements (34, 38) relative to each other in the direction of a pivot axis during pivoting into an operational position, characterized in that the locking device (40) includes a first portion that extends in a first plane parallel to the longitudinal direction of the wiper blade (12) in the operational position, and also includes a second, angled end (42) portion that extends from the first portion in a second plane both parallel to the longitudinal direction of the wiper blade (12) and perpendicular to the pivot axis in the operational position, and further characterized in that a coding device (46, 52) is provided between the connecting element (36) and the connection element (24), allowing the wiper blade (12) to be pivoted into the operational position only if the wiper blade (12) is intended for operation with the associated wiper arm, wherein the coding device comprises a coding cam (48, 54) and a coding recess (50, 56) which fit together and are each arranged separately from one another on at least one of the connection element (24) and the connecting element (36), at least one of the coding cam (48, 54) and the coding recess (50, 56) being disposed on the angled end (42), wherein the coding recess (50, 56) and the coding cam (48, 54) fit together, and wherein the coding recess (50, 56) is arranged on the connecting element (36) and the coding cam (48, 54) is arranged on the connection element (24).

2. The connecting device (10) as claimed in claim 1, characterized in that the locking device (40) is arranged in the form of a bridge or a strap on the connection element (24) and, by means of the angled end (42), holds the connecting element (36) laterally in the operational position.

3. The connecting device (10) as claimed in claim 1, characterized in that the locking device (40) is arranged in the form of a bridge or a strap on the connecting element (36) and, by means of the angled end (42), holds the connection element (24) laterally in the operational position.

4. The connecting device (10) as claimed in claim 1, characterized in that the coding of the coding device (46, 52) is determined by the shape or the position of the coding cam (48, 54) and of the coding recess (50, 56).

5. The connecting device (10) as claimed in claim 1, characterized in that the coding of the coding device (46, 52) is determined by the shape and the position of the coding cam (48, 54) and of the coding recess (50, 56).

6. The connecting device (10) as claimed in claim 1, wherein the coding recess (50, 56) and the coding cam (48, 54) are each arranged separately from one another on the connection element (24).

7. The connecting device (10) as claimed in claim 1, wherein the coding recess (50, 56) and the coding cam (48, 54) are each arranged separately from one another on the connecting element (36).

8. A connecting device (10) for the articulate connection of a wiper arm to a wiper blade (12) according to a side-lock principle, comprising a connecting element (36) that is fastened on the wiper arm and that runs laterally in relation to a connection element (24) fastened on the wiper blade (12) and that carries a bearing element (34, 38) forming a pivot bearing with a bearing element (34, 38) on the connection element (24), said pivot bearing running transversely to a longitudinal direction of the wiper blade (12) and defining a pivot axis, wherein a locking device (40) secures the bearing elements (34, 38) relative to each other in the direction of a pivot axis during pivoting into an operational position, characterized in that the locking device (40) includes a first portion that extends in a first plane parallel to the longitudinal direction of the wiper blade (12) in the operational position, and also includes a second, angled end (42) portion that extends from the first portion in a second plane both parallel to the longitudinal direction of the wiper blade (12) and perpendicular to the pivot axis in the operational position, and further characterized in that a coding device (46, 52) is provided between the connecting element (36) and the connection element (24), allowing the wiper blade (12) to be pivoted into the operational position only if the wiper blade (12) is intended for operation with the associated wiper arm, wherein the coding device comprises a coding cam (48, 54) and a coding recess (50, 56) which fit together and are each arranged separately from one another on at least one of the connection element (24) and the connecting element (36), at least one of the coding cam (48, 54) and the coding recess (50, 56) being disposed on the angled end (42), and wherein the coding recess (50, 56) and the coding cam (48, 54) fit together, and wherein the coding recess (50, 56) is on the angled end (42).
