Abstract:
Wischblatt zum Wischen von Scheiben an Fahrzeugen, mit einem waagebalkenartig aufgebauten Traggestell, das einen mit einem Wischarm verbindbaren Hauptbügel und mit dem Hauptbügel, insbesondere über mehrere Ebenen von Zwischenbügeln, gekoppelte Endbügel aufweist, und mit einem mit den Endbügeln, insbesondere über an den freien Enden der Endbügel vorhandene Halteabschnitte, gekoppelten Wischleistensystem, wobei eine auf das Traggestell wirkende Anpresskraft, die im Betriebszustand des Wischblatts das Wischleistensystems gegen die Scheibe presst, über krafteinleitungsstellen von den Endbügeln auf das Wischleistensystem übertragen wird. Die Erfindung kennzeichnet sich dadurch, dass der Abstand zwischen zwei benachbarten krafteinleitungsstellen kleiner als 40 mm ist.
Abstract:
The invention relates to a windscreen wiper device, especially for motor vehicles, in which the force with which the wiper blade is pressed against the windscreen to be wiped is adjusted according to the actual wiping angle. During the operation of the windscreen wiper, an adjusting lever (7) pivoting on the securing component (3) runs down the axial control curve of a fixed connecting link (5) and thus deflects the pressure spring (8). In order to improve the reliability of the windscreen wiper device and the evenness of the wiping movement, the section (11) of the adjusting lever (7) on the connecting link side is forked and each prong (12) of the fork lies on an axially allocated control curve (24) of the connecting link (5).
Abstract:
The invention relates to a wiper arm for a windscreen wiper system, especially for motor vehicles, which is to be secured in rotation via an aperture (7) in its securing member (1) to a drive spindle (8) by means of a securing device in the form of a securing nut (9) or screw (13) acting axially on the drive spindle (8). In order to simplify the fitting of the wiper arm on the drive spindle (8) and ensure simple removal of the wiper arm from the drive spindle (8) without additional aids and without damaging the wiper arm on the drive spindle (8), the securing device (9, 13) is held captive at least approximately in the fitting position on the securing member (1) in such a way that the wiper arm can be withdrawn from the drive spindle (8) by means of the securing device (9, 13).
Abstract:
A driving crank for a windshield wiper system is disclosed. The crank lever (10) is made of deep-drawn sheet metal. The crank lever (1) has a rear part (2) and a continuous edge (3) drawn to one side of the rear part (2). At one end, the crank lever (1) has an opening (4) with an edge (5) drawn to the same side so as to form an inner cone (6). In order to prevent the inner cone (6) from expanding and to reliably transmit high torques between the driving crank and the shaft to be secured in the opening (4) and vice-versa, the inner cone (6) spreads outwards from the rear part (2).
Abstract:
The invention relates to a process and device for assembling a wiper system on a motor vehicle. Individual components of the wiper system are fastened to the body of the motor vehicle at a distance apart. The individual components (19) are first correctly positioned on the fastening points (26) on the motor vehicle body (25) and detachably fixed to a device which acts as a transport carrier (30). The assembly unit consisting of wiper system and transport carrier (30) is then placed on the body (25) of the vehicle, correctly positioned for assembly. The components (19) of the wiper system are then detached from the transport carrier (30).
Abstract:
Wiper installation with a wiper arm (40) which consists of a securing part (50), an articulation part (60) pivotally articulated thereto, and a guide part (80) holding the wiper blade (31), said guide part being secured to the articulation part (60) in a pivotal manner perpendicularly to the windscreen to be wiped (10) and around an articulation axis (A2). The length of guide part (80) is selected in such a manner that the articulation axis (A2) is arranged roughly in the region of the end of the wiper blade (33).
Abstract:
In a windscreen wiper for motor vehicles, the distribution of the contact pressure along the wiping lip (19) of the rubber wiper blade (18) is influenced by magnetic means (30, 31). In particular, the contact pressure can be displaced from the central region to the end region of the wiper blade when wiping curved windscreens.
Abstract:
A window-cleaning installation comprises at least one cleaning device which preferably executes a back and forth movement on a window pane (12), in particular a windscreen wiper (13), guided at both ends. This window-cleaning device is therefore particularly suited for cleaning large areas without the risk that one of its ends will be lifted, for example by wind pressure. In a preferred embodiment, the window-cleaning device is driven by two counterdriven perforated belts (71a, 71b).
Abstract:
The invention relates to a wiper blade (10) for cleaning vehicle windscreens with a wiper blade body (15) exhibiting a wiper rubber (16) which is connectable to a wiper arm via a wiper blade adapter (11), wherein the wiper rubber (16) exhibits a receiving groove (19, 20) for a spring strip (17, 18) on each of its two longitudinal sides, said spring strip projecting from the receiving groove (19, 20), wherein the two spring strips (17, 18) are disposed in the wiper blade adapter (11) at a defined parallel distance from each other by means of at least one holding element (30) in each case. It is provided according to the invention that the two spring strips (17, 18) are received in holding elements (30), which are U-shaped, in the wiper blade adapter (11) wherein the lateral legs (37, 38) of the holding elements (30) directly embrace the spring strips (17, 18) on their top side and underside, and that the holding elements (30) are received in mounts (29), which are U-shaped in cross-section, of the wiper blade adapter (11).
Abstract:
The invention relates to a wiper blade (10) for the cleaning of windows (1) of motor vehicles, with a carrier element (15) which has a first mounting (16) for the form- fitting fastening of a wiper rubber (11) and a second mounting (22) for fastening at least one spring rail (20) serving as a support element. According to the invention, provision is made that the second mounting (22) in the longitudinal direction of the carrier element (15) forms laterally two guides (23, 24) for the spring rail (20), which embrace the lateral edge regions of the spring rail (20) in a form-fitting manner, and that the region between the guides (23, 24), viewed over the longitudinal direction of the carrier element (15), is constructed at least partially, preferably completely, as an open central zone (28).
