Windshield wiper device

The invention relates to a windshield wiper device a drive motor with a crank pin on the output side, two wiper rods mounted on it, these are hinged to two wiper levers pivoted on ¥ ¥ ¥ ¥ ¥ ual axles and with wiper blades.

A windshield wiper device, a windshield wiper, is a cleaning device which - possibly in cooperation with a windscreen washer system - a window, in particular Keep the windshield of a vehicle clean, i.e. provide a sufficiently large and clear field of vision.

According to the road traffic licensing regulations (§ 4o StVZO) must windshields with automatic windshield wipers, Windshield wiper devices, be provided. The area of action of the windshield wipers is to be dimensioned in such a way that there is sufficient coverage for the driver of the vehicle is created. Furthermore (§35 SfcVZO) there is a sufficient field of vision for the driver required. The Federal Minister of Transport has more details regulated (guideline for the view from motor vehicles, BMV / StV 7 - 8136 U / 62 v. 04o12 "62). All of these regulations show the great importance attached to a sufficient field of vision for the driver. Yet is in rain and / or snow and / or pollution Ie-

only a viewing angle of 35 within the viewing coil prescribed in width. Only the term "sufficient", a relative term, applies to the amount.

Known windshield wiper devices, whether with the same or Opposite wiping field, only clean about one or two sectors of the windscreen. You create under actual Road traffic conditions, at best, require sufficient visibility for the driver. The cleaned one Section of the pane is only part of the prescribed minimum field of vision. It must be noticed that for rain and / or snowfall a not inconsiderable part of the requirement of a sufficient field of vision, obviously is suspended in the absence of a practicable technical solution.

In practice, the disadvantage of conventional windshield wiper devices affects especially in the case of a dense line of vehicles, that high or above the lane, e.g. on Sign gantries over the autobahn, signs attached due to vehicles driving close ahead only then into the The driver's field of vision is reached when the line of sight is already outside the area cleared by the windshield wiper device Bereiohs of the windshield is. The value or worthlessness of traffic signs that cannot be seen is required no explanation. In order to still be able to recognize such traffic signs or even to attempt to do so inappropriately To undertake, the driver must leave the posture required for safe control of the vehicle, This is especially true in road conditions that are already less safe due to rain and / or snow.

The invention is based on the object of a windshield wiper device of the type described at the beginning or a similar type that complies with the provisions of the Road Traffic Licensing Regulations as well as reasonable requirements, with which the disk has not been used so far painted areas can be cleaned.

According to the invention, this object is achieved in that on
the drive motor on the output side, a second crank pin is arranged diametrically to the crank pin so that the wiper rods are each attached to one of the crank pins.

are, and that the wiper blade in the shape and width of the window; is adapted. This measure is approximately horizontal
The position of the wiper blade allows practically the entire window
or to clean the entire width and height of the windscreen so that a full field of vision can be maintained even in rain and / or snow. Another key advantage ■

'15 is that largely the previously known
parts used in conventional windshield wipers, ',

like the drive motor, the wiper rods, the wiper axles j and the wiper levers are still used. It is therefore necessary

for the introduction of the windshield wiper device, for example in the ■

Automobile manufacturing does not require a profound change. Finally ■

the invention makes a very important contribution to Si- '■

safety in road traffic and everywhere where previously; with windshield wiper devices always only a smaller view '

A modification of the invention consists in that the steering members have different lengths. So that's it
allows also panes of trapezoidal shape, where the upper
and the lower edge are not parallel to each other, in
to coat their entire surface.

According to one embodiment of the invention, the wiper blade
sloping slightly on at least one of its two sides

is promoted.

Finally, one embodiment of the invention consists in that the drive motor and / or at least the Wisoherachsen jointly or individually with their geometric axis in Direction on the disc pivotable, adjustable. By setting a slight incline towards the disc it is achieved that the Anpreßdruok of the wiper blade over is kept about the same all the way.

In the drawing, the invention is exemplified and schematized shown. It show in perspective view

1 shows a windshield wiper device in a working position just before the zenith, and

2 shows the windshield wiper device in its resting position, at the same time lowest working position.

According to the drawing, a windshield wiper device consists essentially of a drive motor 10 on the output side two diametrically arranged crank pins 11 and 12, two identical wiper rods 21 and 22, two of each other same, each on a wiper shaft 31 (broken off) and 32 pivotably mounted wiper levers 41 and 42, two steering members 51 and 52 articulated on them, which are spaced apart from one another attack together on a wiper blade 60. The windshield wiper device is arranged in the usual way below the windshield 70 of a vehicle.

In operation, the wiper rods 21 and 22, the wiper levers 3I and 32 and the steering members 51 and 52 in opposite directions driven to each other. As a result of the geometry of the linkage, the wiper blade 60 moves up and down causes the whole width of the (front) pane.
