Connecting device for a wiper arm
First Claim
1. Connecting device (10) for a wiper arm (14) and a wiper blade (12), with a first connecting part (16) on the wiper blade and a second connecting part (18) on the wiper arm, which parts are juxtaposed in an operational position and are connected to each other via a hinge element (44) including a bolt (26) and a counter-hinge hole (42) so that the first and second connecting parts (16, 18) can be swiveled around a hinge axis and partially engage with one another at least via securing means (32) including a bridge (34) and a limit (36), characterized in that the first connecting part (16) has a receptacle (38) for accommodating the securing means (32), the receptacle (38) having a base (60) and a longitudinal shaped portion (66) that extend parallel to the hinge axis and to each other, characterized in that the first connecting part (16) is one of detachable from and connectable to the second connecting part (18) by rotation of at least one of the connecting parts (16, 18) around the hinge element (44) by at least a detachment angle (50), characterized in that the limit (36) has a shoulder (56) and the longitudinal shaped portion (66) is a groove, characterized in that the groove is dimensioned to accommodate the shoulder (56) when one of detaching and connecting the connecting parts (16, 18), characterized in that the bridge (34) substantially covers and is positioned above the base (60) and the groove when the first connecting part (16) is connected to the second connecting part (18), and characterized in that the base (60) is positioned a first distance from the bridge (34) extending in a direction parallel to the limit (36) and the groove is positioned a second distance from the bridge (34) extending in a direction parallel to the limit (36) when the first and second connecting parts (16, 18) are in the operational position, the second distance being greater than the first distance.

Abstract
The invention relates to a connecting device (10) for a wiper arm (14) and a wiper blade (12). Said wiper blade comprises a first connecting part (16) on the wiper blade end and a second connecting part (18) on the wiper arm end, both parts being juxtaposed in the operational position and being connected to each other via a hinge element (44) so that they can be swiveled about a hinge axis. Securing means (32) are provided so that the first and second connecting part (16, 18) engage with each other. The invention is characterized in that the first connecting part (16) has a recess (38) for accommodating the securing means (32) in which a longitudinal, shaped portion (66) is provided which is parallel to the hinge axis. The invention also relates to a flat bar wiper blade (12) which comprises a first connecting part (16) for fastening the flat bar wiper blade (12) to a wiper arm (14). The connecting part (16) comprises a counter-hinge element (42) so that the flat bar wiper blade (12) can be connected to the wiper arm (14) so that it can be swiveled about a hinge axis. Said flat bar wiper blade is characterized in that a recess (38) for accommodating a securing means (32) is provided in which a longitudinal, shaped portion (66) is provided which is parallel to the hinge axis.
