Definitions
- the invention relates to a windshield wiper device, in particular for a motor vehicle, with at least one wiper arm which is locked on a shaft with at least one locking element.
- Pedestrians are completely unprotected when they collide with vehicles.
- the unyielding, hard parts underneath the bonnet often lead to serious injuries when a pedestrian hits a vehicle.
- the windshield wiper device is located in an area in which pedestrians frequently encounter a vehicle when it hits it.
- the windshield wiper devices which are generally known from the prior art have the disadvantage that they pose a great risk of injury to the pedestrian in the event of an impact on the vehicle.
- the object of the invention is to improve a windshield wiper device of the type mentioned at the outset in such a way that the risk of injury to a pedestrian in the event of a collision with a vehicle is reduced in the future.
- the invention achieves the stated object by a windshield wiper device of the type mentioned at the outset, in which, according to the invention, the at least one locking element can be destroyed in the event of an impact on the at least one wiper arm. This means that the at least one wiper arm can be ben, so that the risk of injury to the pedestrian is reduced.
- the at least one wiper arm can have a sleeve that can be inserted over the shaft.
- the length of the sleeve corresponds approximately to a displacement path of the wiper arm on impact. In the event of an impact, the shaft is pushed into the sleeve according to the possible displacement path. The longer the sleeve, the greater the displacement.
- the length of the sleeve can be individually adapted to the respective vehicle type depending on the space available. Therefore, the shaft and a wiper motor can be uniform components for all vehicle types, which saves costs.
- the shaft can be connected to the at least one wiper arm in a positive and / or non-positive manner.
- a molded part can be arranged between the shaft and the sleeve.
- the molded part creates a positive connection between the sleeve and the shaft. If the molded part is a ring which has sharp-edged teeth on its outer circumference, the teeth can dig into the sleeve when the wiper arm is mounted on the shaft.
- the assembly staff can first align the wiper arm in its optimal parking position during assembly and then press it onto the sharp-edged teeth of the ring, as a result of which the wiper arm is fixed in its optimal position.
- the molded part can also be formed in one piece with the shaft. Then the shaft can have knurling in a certain area, for example.
- the diameter of the shaft can have a shoulder on which an inner edge of the sleeve can be supported.
- the shoulder and the inner edge in the direction of the impact force likewise form a positive connection that locks the sleeve on the shaft.
- the inner edge of the sleeve forms a predetermined breaking point. When a person hits the wiper arm, the inner edge shears off the sleeve, so that the sleeve can slide over the shaft in the direction of impact.
- the at least one wiper arm can be non-positively connected to the shaft by means of a screw connection.
- the shaft expediently has a threaded bore or a section having an external thread.
- the molded part can be easily pressed into the wiper arm when tightening a screw or nut.
- a pin can be inserted through the sleeve and / or the shaft.
- the pin locks the sleeve on the shaft.
- the pin shears off so that the sleeve can slide over the shaft.
- the pin can have a predetermined breaking point in its area that is most stressed during the impact.
- a spring element to at least partially encompass the shaft, the spring element locking the sleeve with the shaft in the axial direction. When a person hits the wiper arm, the spring element is destroyed. In order to facilitate the destruction in the event of an impact, the spring element can have a predetermined breaking point.
- the pin and / or the spring element can be made of plastic or metal.
- a vent opening can be provided in the sleeve. This allows the air present in the sleeve to escape when the wiper arm is pressed onto the shaft during assembly and when a person hits the wiper arm.

- FIG. 7b shows a longitudinal section through the shaft from FIG. 7a.
- FIG. 1 shows a windshield wiper device 10 in which a sleeve 11 of a wiper arm 12 is inserted over a shaft 13.
- the sleeve 11 is provided with an inner edge 14 which rests on a shoulder 15 of the shaft 13 and thus locks the sleeve on the shaft from top to bottom. If, when a person hits the wiper arm 12, a force acts on the wiper arm 12 from above, the inner edge 14 shears off the sleeve 11. As a result, the sleeve 11 and the wiper arm 12 are displaced downward, so that the wiper arm 12 yields and the risk of injury to the person hitting the wiper arm 12 is reduced.
- a molded part 16 see FIGS.
- the molded part 16 has sharp-edged teeth on its outer circumference.
- a nut 17 is screwed with a section 18 having an external thread, the sharp-edged toothing of the molded part 16 is pressed into the sleeve 11.
- the sleeve 11 therefore has an area 19 with a smaller inside diameter in the area of the molded part 16.
- the molded part 16 has an inner contour adapted to the outer contour of the shaft 13. As a result, a positive connection is also produced between the molded part 16 and the shaft 13.
- the wiper arm 12 Due to the positive connection between the shaft 13 and the molded part 16 and the molded part 16 and the sleeve 11, a torque can be reliably transmitted from the shaft 13 to the wiper arm 12. Furthermore, the wiper arm 12 has an opening closed with a closure cap 100. Through it, the wiper arm 12 can be screwed to the shaft 13.
- the figures 2a to 2e show different embodiments of shafts 20, 21, 22, 23 and 24 and different embodiments of shaped parts 25, 26, 27, 28 and 29.
