Device for fixing a wiper blade on a plastic windshield wiper assembly for vehicles, in particular Motor vehicles

The invention relates to a device for attaching a wiper blade to a plastic windshield wiper arm for Vehicles, in particular motor vehicles, in which the end part of the wiper arm has the shape of an Ealcens and has two cheeks and a shaft connecting them to one another having bearing part of the wiper blade can be hooked.

Such devices are known. In these devices, a bow-shaped spring is mounted on the shaft, the approximately parallel ends of which generate an outward spring force when pressed together. In the area of the bearing, the two bow ends of this spring are provided with inwardly directed reinforcements, which further enclose the shaft and prevent it from falling out. One outside of the spring is provided with a latch. The hook-shaped end part of the wiper arm has a latching recess in the free hook part and is pushed onto the spring, the spring being compressed and the latching nose then engaging in the ^r u, from nc guild.

The object of the invention is to provide a device of the type mentioned at the outset which is more simply designed and in which the spring with locking lug can be dispensed with. This is achieved according to the invention achieved that the hook is mounted directly on the shaft, that the free hook part is resilient and in the area of the bearing a further enclosing the shaft

Has reinforcement and tapers like a beak. The at the spring required in the known devices is omitted that is, because the hook-shaped end part of the wiper arm itself is designed as a spring. Falling out of its own accord the shaft and thus the wiper blade is avoided by the special shape of the hook-shaped end part of the wiper arm.

So that this end part can be pushed onto the shaft more easily, the end of the deflectable hook part is from the opposite hook part bent away.

The invention is explained in more detail using an exemplary embodiment. Show it

The end part of a Scheibon wiper arm shown in FIG is made of plastic like the entire windscreen wiper arm. The other end of the wiper arm, not shown, is connected in a known manner to the Wlschlagerwelle. Of the The end part has the shape of a hook 10.

12 provided, which further encloses the shaft (Fig. 2), and runs from the reinforcement 12 from beak-shaped. That End of the deflectable hook part 11 is from the opposite Hook part 13 bent away.

In FIGS. 2 and 3, the bearing part of a wiper blade which is not shown in detail is shown. The bearing part essentially consists of two parallel cheeks 14, 15 which are connected to one another by a shaft 16. The shaft 16 is designed here as a rivet. In the case of plastic wiper blades, however, it can also be designed as a round web and made in one piece with the cheeks Ik , 15.

The hook 10 can now be hooked directly into the bearing part, as indicated in FIG. 2, so that it is mounted directly on the shaft 16. When hooked, the hook becomes initially a little open, and then the hook part 11, which is deflected back, springs back again. The shaft 16 can therefore not. fall out of the bearing point automatically.

The use of the subject matter of the invention is not limited to windshield wiper systems. He can too for wiper systems for rear and side windows as well as for those for headlights and other cover glasses can be provided by luminaires.
