Device for the jointed connection of a wiper blade
First Claim
1. A device (10) for a jointed connection of a wiper blade (12) to a wiper arm (18), wherein a joining element (20) which is to be connected to the wiper blade (12) has a joint part (32) which forms a joint with a joint part (40) on a connecting element (38) to be connected to the wiper arm (18), and one of the joint parts (40) is a hub (40) which is open in a longitudinal direction of the joining element (20) and, in a fitted state, is supported with respect to the connecting element (38) in a direction opposed to the hub opening (42), and wherein side walls (30, 56) of the joining element (20) and of the connecting element (38) overlap, characterized in that the side walls (56) of the connecting element (38) have cutouts (44) which are open toward a wiper strip (14) and into which projections (34) on the joining element (20) enter in an operating position of the wiper blade (12) such that the joining and connecting elements (20, 38) are locked against each other in the longitudinal direction, and characterized in that the joining element (20) is designed as a sheet-metal claw and the projections are formed by tabs (34) which are cut free from the side walls (30) of the joining element (20) and are bent toward the connecting element (38) at an acute angle with respect to the side wall (30) and enter into the cutouts (44) therein.

Abstract
The invention relates to a device (10) for the jointed connection of a wiper blade (12), having a wiper arm (18), wherein a connector (20) intended to be connected to the wiper blade (12) has a joint part (32) which forms a joint with a joint part (40) on a connector (38) intended to be connected to the wiper arm, and one of the joint parts (40) is a hub (40) open in the longitudinal direction of the associated component (20 or 28), the hub being supported with respect to the other component (38) in the direction opposite (42) the hub opening (42) when in the installed state, wherein the side walls (30, 56) of the connector (20) and of the connector (38) overlap. It is suggested that the side walls (56) of one component (38) has recesses (44) which are open to the wiper strip (14), and plunge into the projections (34) in the wiper blade (12) operating position, such that both components (20, 38) are locked against each other in the longitudinal direction.
