B. 10 to 40 mm, in particular 25 mm.

Another variant provides that in addition to the first and second bearing a fourth and possibly another Bearings are provided so that the variety is even higher.

The central part preferably has essentially two Sidewalls, which are connected to each other via webs are. The width of the webs is chosen so that usual Wiper arm hook still in the connector, d. H. between the sidewalls, can be hung. In addition, by the connection of the two side panels via webs of material can be saved compared to a connecting element, which is essentially solid. Preferably, the Bearing provided in the webs. This has the significant advantage that due to the web walls elastic snap-snap connections can be created which the hinge pin and / or the bearing pin relatively wide reach around and the connecting element still effortlessly on the Hinged bolts snap on or the bearing journal of the Locking member can be easily snapped into the central part.

The webs are in the direction of. Wiper strip open. This also has the advantage that the opening direction of the Bearing is perpendicular to the longitudinal direction of the wiper arm, see above  that an unwanted loosening or loosening of the wiper blade from the Wiper arm is prevented.

An optimal placement of the wiper arm hook on the central part created in that a section of the outer contour of a Web corresponds to the inner contour of the wiper arm hook. This The outer contour of the web fits snugly against the On the inside of the wiper arm hook and becomes play-free from it held.

In addition, the invention provides that the outside of the Sidewalls with at least partially concentric around the arranged first and / or second bearing point Material surveys is provided. These material surveys lie on the inside of the wiper blade box and provide for minimal friction on the connector Wiper blade.
