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.

Claims

1. A device (10) for the 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 associated element (20 or 38) and, in a fitted state, is supported with respect to the other element (38) in the 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 one element (38) have cutouts (44) which are open toward the wiper strip (14) and into which projections (34) on the other element (20) enter in an operating position of the wiper blade (12) such that the two components (20, 38) are locked against each other in the longitudinal direction.

2. The device (10) as claimed in claim 1, 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) and enter into the cutouts (44) therein.

3. The device (10) as claimed in claim 2, characterized in that the side walls (30) of the joining element (20) as one joint part bear a joint pin (32) which is arranged between the outer end of the joining element (20) and the tabs (34).

4. The device (10) as claimed in claim 3, characterized in that a cutout (36) is provided in the base (28) of the joining element (20) in the region of the joint pin (32).

5. The device (10) as claimed in claim 1, characterized in that the connecting element (38) has latching studs (48) or a latching lug (50) which can latch into corresponding latching holes (52) in the wiper arm (18).

6. A wiper arm (18) for use with a device (10) as claimed in claim 1, characterized in that lateral pockets (46) are provided on the wiper arm (18) in the region of the cutouts (44) in the side walls (56) of the connecting element (38).

8. The device (10) as claimed in claim 4, characterized in that the connecting element (38) has latching studs (48) or a latching lug (50) which can latch into corresponding latching holes (52) in the wiper arm (18).

9. A wiper arm (18) for use with a device (10) as claimed in claim 8, characterized in that lateral pockets (46) are provided on the wiper arm (18) in the region of the cutouts (44) in the side walls (56) of the connecting element (38).

7. (canceled)

10. A wiper blade (12) comprising a device (10) for the jointed connection of the wiper blade (12) to a wiper arm (18), wherein a joining element (20) 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 associated element (20 or 38) and, in a fitted state, is supported with respect to the other element (38) in the 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 one element (38) have cutouts (44) which are open toward the wiper strip (14) and into which projections (34) on the other element (20) enter in an operating position of the wiper blade (12) such that the two elements (20, 38) are locked against each other in the longitudinal direction.

11. The device (10) as claimed in claim 10, 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) and enter into the cutouts (44) therein.

12. The device (10) as claimed in claim 10, characterized in that the side walls (30) of the joining element (20) as one joint part bear a joint pin (32) which is arranged between the outer end of the joining element (20) and the tabs (34).

13. The device (10) as claimed in claim 10, characterized in that a cutout (36) is provided in the base (28) of the joining element (20) in the region of the joint pin (32).

14. The device (10) as claimed in claim 10, characterized in that the connecting element (38) has latching studs (48) or a latching lug (50) which can latch into corresponding latching holes (52) in the wiper arm (18).

15. A wiper arm (18) for use with a device (10) as claimed in claim 10, characterized in that lateral pockets (46) are provided on the wiper arm (18) in the region of the cutouts (44) in the side walls (56) of the connecting element (38).

16. The device (10) as claimed in claim 10, characterized in that the connecting element (38) has latching studs (48) or a latching lug (50) which can latch into corresponding latching holes (52) in the wiper arm (18).
