Connecting element for the articulated connection of a wiper blade to a wiper arm
First Claim
1. A wiper assembly, comprising:
- a wiper arm (12) of a window wiper (10), the wiper arm including a hook-shaped end with a curved portion having an outer circumference; and
a connecting element (36) for an articulated connection of a wiper blade (14) to the wiper arm (12), the connecting element (36) including;
a hub (50), which is open toward a vehicle window (16), for a bearing pin (26) fastened to the wiper blade (14);
at least one elastically flexible spring tongue (46) in order to keep the bearing pin (26) in the open hub (50); and
at least one bearing surface (60) to support the connecting element (36) on the hook-shaped end (28) of the wiper arm (12), whereinthe hub (50) is open over half of its circumference, and the spring tongue (46), which blocks the opening of the hub (50) by a latching cam (48), yields elastically in a direction of the bearing surface (60), with a distance between the bearing surface (60) and the spring tongue (46) being dimensioned such that, in a fitted state, the outer circumference of the hook-shaped end (28) blocks the spring tongue (46) in the direction of the bearing surface (60).

Abstract
The invention is based on a connecting element (36) for the articulated connection of a wiper blade (14) to a wiper arm (12) of a window wiper (10), wherein the connecting element (36) has a hub (50), which is open towards a vehicle window (16), for a bearing pin (26) fastened to the wiper blade (14), and at least one elastically flexible spring tongue (46) in order to keep the bearing pin (26) in the open hub (50), and the connecting element (36) furthermore has at least one bearing surface (60) in order to support it on a hook-shaped end (28) of the wiper arm (12). It is proposed that the hub (50) is open over half of its circumference, and the spring tongue (46), which blocks the opening of the hub (50) by means of a latching cam (48), yields elastically in the direction of the bearing surface (60), wherein the distance between the bearing surface (60) for the hook-shaped end (28) and the spring tongue (46) is dimensioned in such a manner that, in the fitted state, the hook-shaped end (28) blocks the spring tongue (46) in the direction of the bearing surface (60).
