Abstract

The invention relates to an arrangement for the detachable connection of a wiper blade on a swivelable wiper arm of a wiper arrangement for windows of motor vehicles, with a bushing that can be connected to the wiper blade or arranged on it for accommodating a plug-in axis of the wiper arm and with a device to lock the plug-in axis in the bushing at least in an operating position of the wiper blade, in which the directions of the longitudinal extension of the wiper blade and the wiper arm are aligned approximately parallel to one another. It is provided that the device for locking includes a catch hook (20) arranged on the wiper blade (12), which in the operating position partially grips around the wiper arm (10) near the plug-in axis (16) and forms an angular limit stop for the wiper blade (12).

Claims

1. An apparatus for the detachable connection of a wiper blade (12) on a swivelable wiper arm (10) of a wiper for windows of motor vehicles, the apparatus comprising a bushing (18) one of connected to the wiper blade and arranged on the wiper blade for accommodating in a lockable manner a plug-in axis (16) connectable to the wiper arm to define a pivot axis of the wiper blade, wherein the plug-in axis (16) is arranged on one side of a second coupling element (15) slidable over a free end (34) of the wiper arm (10) and detachably lockable therewith, whereby the second coupling element (15) features a spring clip (36) having an inner side and a locking tooth (38) in the inner side pointing toward the wiper arm (10), which in a position that is slid on the wiper arm (10) engages in a recess (42) in the free end of the wiper arm (10) and whereby an unlocking handle (40) for manually unlocking the locking tooth (38) is arranged on a free end of the spring clip (36) on a side of the second coupling element (15) opposite the plug-in axis (16), the locking tooth (38) being spaced from the unlocking handle (40) along a length of the spring clip (36).

2. An apparatus according to claim 1, wherein the second coupling element (15) is latchable to the free end (34) of the wiper arm (10).

3. An apparatus according to claim 1, wherein the unlocking handle (40) projects in a direction opposite the plug-in axis (16).

4. An apparatus according to claim 1, wherein the second coupling element (15) has a wall providing the spring clip (36).

5. An apparatus according to claim 4, wherein the wall defines grooves extending along the spring clip (36).

6. An apparatus according to claim 5, wherein the grooves at least partially separate the spring clip (36) from a remainder of the wall.

7. An apparatus according to claim 5, wherein the locking tooth (38) is positioned on the spring clip (36) directly between the grooves.

8. An apparatus according to claim 4, wherein the wall faces in a direction opposite the plug-in axis (16).

9. An apparatus according to claim 4, wherein the second coupling element (15) defines an opening for receiving the free end (34) of the wiper arm (10), wherein the first-mentioned wall is on one side of the opening, and wherein the second coupling element has another wall from which the plug-in axis (16) projects, the other wall being on a side of the opening opposite the first-mentioned wall.

10. An apparatus according to claim 9, wherein the locking tooth (38) is positioned on the spring clip (36) within the opening receiving the free end (34) of the wiper arm (10).

11. An apparatus according to claim 1, wherein locking brackets (44) are provided on a free end of the plug-in axis (16) to axially lock the plug-in axis (16) to the bushing (18).

12. An apparatus for the detachable connection of a wiper blade (12) on a swivelable wiper arm (10) of a wiper for windows of motor vehicles, the apparatus comprising a bushing (18) one of connected to the wiper blade and arranged on the wiper blade for accommodating in a lockable manner a plug-in axis (16) connectable to the wiper arm to define a pivot axis of the wiper blade, wherein the plug-in axis (16) is arranged on a second coupling element (15) slidable over a free end (34) of the wiper arm (10) and detachably lockable therewith, whereby the second coupling element (15) features a spring clip (36) having an inner side and a locking tooth (38) in the inner side pointing toward the wiper arm (10), which in the position that is slid on the wiper arm (10) engages in a recess (42) in the free end of the wiper arm (10) and whereby an unlocking handle (40) for manually unlocking the locking tooth (38) is arranged on the free end of the spring clip (36), the unlocking handle (40) projecting away from the plug-in axis (16), wherein the second coupling element (15) defines an opening for receiving the free end (34) of the wiper arm (10), wherein the second coupling element has one wall from which the plug-in axis (16) projects on one side of the opening and another wall on a side of the opening opposite the one wall, the unlocking handle (40) being on the other wall, and wherein the locking tooth (38) is positioned on the spring clip (36) within the opening receiving the free end (34) of the wiper arm (10).

13. An apparatus according to claim 12, wherein the second coupling element (15) is latchable to the free end (34) of the wiper arm (10).

14. An apparatus according to claim 12, wherein the other wall provides the spring clip (36).

15. An apparatus according to claim 14, wherein the wall defines grooves extending along the spring clip (36).

16. An apparatus according to claim 15, wherein the grooves at least partially separate the spring clip (36) from a remainder of the wall.

17. An apparatus according to claim 14, wherein the wall faces away in a direction opposite the plug-in axis (16).

18. An apparatus according to claim 12, wherein locking brackets (44) are provided on a free end of the plug-in axis (16) to axially lock the plug-in axis (16) to the bushing (18).

19. An apparatus according to claim 12, wherein the locking tooth (38) is spaced from the free end of the spring clip (36) along a length of the spring clip (36).

20. An apparatus according to claim 12, wherein the locking tooth (38) is spaced from the unlocking handle (40) along a length of the spring clip (36).
