`
`In wiper blades
`the support element is meant to assure the
`evenest possible distribution of the wiper blade contact pressure
`on the windows, over the entire swept field swept by the wiper
`blade . By means of a suitable curvature of the unstressed support
`element - that is, when the wiper blade is not applied to the
`wiper blade -- the ends of the wiper strip, which in wiper blade
`operation is pressed entirely against the window, are urged toward
`the window by the then-stressed support element, even if the radii
`of curvature of spherically curved vehicle windows differ in every
`position of the wiper blade . The curvature of the wiper blade
`must accordingly be somewhat greater than the greatest curvature
`measured in the swept field of the window to be wiped . The
`support element thus replaces the complicated support bracket
`construction, having two spring rails disposed in the wiper strip,
`of the kind employed in conventional wiper blades.
`The invention takes as its point of departure a wiper blade
`In a known
`wiper blade of this type (German Patent DE-PS 12 47 161), the
`wiper blade, or its support element, which for reasons of
`distributing the contact pressure protrudes far past the wiper
`strip in the middle region of the wiper blade, can on the one hand
`be engaged from below, on the front side facing into the wind,
`with an attendant buildup of overpressure, by this overpressure.
`On the other hand, on the back side facing away from the wind,
`because of the structural form noted above, a considerable
`negative pressure builds up . Although the wiper blade, which
`during operation usually executes a pendulum motion, constantly
`changes its position relative to the oncoming relative wind, even
`then one of its long sides is always more or less . greatly exposed
`
`Z
`

`
`

`
`

`
`to the wind and is therefore called the front side, while its
`other long side is accordingly also thought of as the back side.
`At relatively high vehicle speeds, given the cooperation of these
`two aforementioned pressures, both of which are oriented counter
`to the wiper blade contact pressure, this contact pressure is
`reduced at least enough that proper wiping is no longer possible.
`Increasing the wiper blade contact pressure against the window at
`high vehicle speeds could admittedly reduce the severity of this
`problem, but at lower vehicle speeds, when the liftoff tendency is
`
`less, the friction between the wiper blade and the window
`increases ; this leads to undesirable noise buildup and to
`excessively high stress on the drive components and on the rubber
`of the wiper.
`
`of the Invention
`
`Y the wiper blade
`ofthe
`via the leading-edge face that faces into the
`wind, a force component aimed at the window is built up, which
`counteracts the liftoff tendency of the two pressures and thus
`assures excellent cleaning quality, at least in the region of the
`swept field swept by the wiper blade, that is, the region that is
`important to the vehicle's driver . Depending on the size of the
`leading-edge face and/or on the size of the approach angle a, this
`auxiliary contact pressure can be adapted to the variable demands
`that depend on the type of vehicle . It is also advantageous in
`the arrangement of the invention that as a function of the vehicle
`speed, the contact pressure rises or falls with this speed . Thus
`a suitably "high auxiliary contact pressure" is opposed only to
`the liftoff tendency that occurs at high speed.
`A compact wiper strip is obtained if the leading-edge face
`is disposed on the face .of the support element facing away from
`the window . The auxiliary contact pressure is then distributed
`not in point form but areally, over the entire length of the wiper

`blade .

`
`The embodiment of a leading-edge face can advantageously by
`attained in that it is embodied on a separate, elongated component
`that is solidly joined to the support element.
`A simple structure of such a separate component is obtained
`in that, seen in cross section, it has at least approximately the
`shape of a triangle, one side of which contacts the face of the
`support element facing away from the window, and also that the
`leading-edge face is embodied on another side of the triangle . In.
`10 certain cases, it can be advantageous to equip the leading-edge
`face at least partially with a hollow curvature facing into the
`wind .

`
`Securing the component to the one side of the support
`element is achieved economically by a glued connection . So that
`the distribution of the contact pressure effected by the support
`element will not be impaired, the component is made from a rubber-
`elastic material whose hardness is no greater, and is preferably
`less, than the hardness of the rubber-elastic wiper strip.
`Advantages in terms of production are attained if the component is
`made from a suitable plastic.
`The length, and the width and height projected in the
`operating direction of the wiper blade, of the leading-edge face
`is designed to suit the requirements . In certain cases it is
`expedient if the leading-edge face extends at least nearly over
`the entire length of the wiper blade.
`Further advantageous refinements and features of the
`invention are recited in the ensuing description of an exemplary
`embodiment shown . in the accompanying drawing.

`
`Description of the
`

`
`Embodiment
`
`5
`
`A wiper blade 10 shown in Figs . 1 and 2 has a single- or
`multi-part, elongated, spring--elastic support element 12, to whose
`
`underside an elongated, rubber-elastic wiper strip 15 is secured
`longitudinally axially parallel to it . A connection device 16 is
`disposed on the top side of the support element, and with its aid
`the wiper blade 10 can be'detachably connected to a driven wiper
`arm 18 . A hook acting as a counterpart connection means is formed
`onto the free end 20 of the wiper arm 18 and grasps a pivot pin 22
`that belongs to the connection device 22 of the wiper blade . The
`securing between the wiper arm 18 and the wiper blade 10 is taken
`on by securing means not shown in further detail but known per se
`and embodied as adapters . The wiper arm 18 'and thus also the hook
`on the end 20 of the arm is urged in the direction of the arrow 24 ,
`toward the window to be wiped, whose surface to be wiped is
`suggested in Fig . 1 by a dot-dash line 26 . Since the dot-dash
`line 26 is meant to represent the greatest curvature of the window
`surfaces, it is quite apparent that the curvature of the wiper
`blade 10, which rests with its two ends on the window, is greater
`than the maximum curvature of the window . Under the contact
`pressure (arrow 24), the wiper blade presses with its wiper lip 28
`over its entire length against the window surface 26 . This causes
`a tension to build up in the bandlike, spring-elastic support
`element 12, and this tension assures a proper contact of the wiper
`strip 14 or wiper lip 28, over their entire length, with the motor
`vehicle window.
`The particular design of the wiper blade 10 will be
`described in further detail, especially in terms of Figs . 3 and 4.

`
`away from the windshield 25, a single- or multiple-part component
`32 extending longitudinally of the wiper blade 10 is secured ; it
`is made from a rubber-elastic material, preferably a plastic,
`whose hardness is less than the hardness of the rubber-elastic
`wiper strip 14 . This wiper strip 14 is disposed on the lower face
`34, toward the window 25, of the support element 12 . As Fig . 1
`shows, the component 32 extends over the entire length of the
`wiper blade 10 . It has a cross section in . the shape of a triangle
`or wedge (Fig . 3) . In the exemplary embodiment, to that end, the
`shape of a non-isosceles triangle has been selected . The longest
`side 36 of this triangle forms a leading-edge face for the
`relative wind created by the motor vehicle, which is symbolized by
`the arrow 38 in Fig . 3 . A second, shorter side 40 of the
`triangular shape faces toward the upper face 30 of the support
`element 12 . The two faces, facing one another, of the support
`element 12 and 40 of the component 32 are joined together by
`gluing .
`
`To explain the mode of operation of the wiper blade of the
`invention, see Fig . 4, in which all the necessary parts of the
`wiper blade are shown in basic form . During operation . of the
`wiper blade, whose operating motion is represented by the double
`arrow 42 when the wiper blade is displaced with its wiper strip 14
`over the surface 26 of the window, the support element 12 is
`located in a plane that extends substantially parallel to the
`surface 26 of the window . The wiper blade 10 then experiences a
`contact pressure 52 (Fig . 3) that is countered during wiper blade
`operation, especially at high vehicle speeds, by a liftoff
`tendency acting in the direction of the arrow 54 in Fig . 4 . Since
`the leading-edge face 36 of the component 30 facing into the wind
`38, and forms an acute angle a with the surface 26 of window 25,
`the pressure of the relative wind 38 generates a force component
`that is represented in Fig . 4 by the arrow 56 . This force
`component 56 acts counter to the liftoff tendency (arrow 54) in
`Fig . 3 and thus keeps the contact pressure (arrow 52) within the

`
`legally prescribed range . In a departure from the exactly
`triangular-cross-sectional shape shown in Fig . 3 for the component
`12, this component can also be embodied such that its side facing
`into the wind 38 is provided with a hollow curvature 60 . which is
`represented in Fig . 4 by a dot-dash line . But even with the
`provision of a hollow curvature on the side toward the wind 38,
`the component 30 maintains its basically triangular cross-
`sectional shape and thus-also the possibility of the development
`of a force component (arrow 56 in Fig, 4) from the contact
`pressure with which the wind (arrow 38) meets the curved leading-
`edge face 60 .

`
`Abstract
`
`A wiper blade (10) is proposed that . serves to clean windows
`of motor vehicles . The wiper blade has an elongated, rubber-
`elastic wiper strip (14) which can be placed against the window to
`be wiped and is disposed substantially longitudinally axially
`parallel to one face, that is, the face oriented toward the
`window, of a stri.plike, spring-elastic support element (12), which
`is connected to a wiper arm (18) that is driven crosswise to the
`length of the wiper blade and can be urged toward the window.
`Even at high vehicle speeds, a requisite wiper blade contact
`pressure for attaining a swept field clean enough to meet legal
`requirements is achieved if the wiper blade (10) is provided with
`a leading-edge face (36 or 60), which extends longitudinally of
`the wiper blade and substantially parallel to the window and faces
`into the wind (arrow 38), and which crosswise to its length forms
`an acute angle with the window.

`
`Stand der Technik
`
`Bei Wischblattern der im Oberbegriff des Anspruchs 1 be-
`zeichneten Art soll das Tragelement liber das gesamte vom
`wischblatt bestrichene Wischfeld eine moglichst gleichm&Sige
`
`verteilung des vom Wischerarm ausgehenden Wischblatt-
`AnpreZdrucks an der Scheibe gewahrleisten . Durch eine ent-
`sprechende Krummung des unbelasteten Tragelements - also
`wenn das Wischblatt nicht an der Scheibe anliegt - werden
`die Enden der im Betrieb des Wischblatts vollstandig an der
`
`Scheibe angelegten Wischleiste durch das dann gespannte Tra-
`gelement zur Scheibe belastet, such wenn rich die Krummungs-
`radien von spharisch gekrummten Fahrzeugscheiben bei jeder
`Wischblattposition andern . Die Krummung des Wischblatts mu13
`also etwas starker sein als die im Wischfeld an der zu wi-
`schenden Scheibe gemessene starkste KrAmmung . Das Tragele-
`ment ersetzt somit die aufwendige Tragbugelkonstruktion mit
`
`zwei in der Wischleiste angeordneten F'ederschienen, wie sie
`bei herkommlichen Wischbldttern praktiziert wird.
`
`Die Erfindung geht aus von einem Wischblatt nach der Gattung
`des Anspruchs 1 . Bei einem bekannten Wischblatt dieser Art
`
`Costco Exhibit 1002, p. 23
`
`
`
`
`

`
`- 2 -
`
`(DE-PS 12 47 161) kann einmal das Wischblatt bzw . dessen aus
`Granden der Auflage-Druckverteilung im Wischblatt-
`Mittelbereich weit liber die Wischleiste ragende Tragelement
`
`auf der dem Fahrtwind zugewandten Vorderseite unter dem Auf-
`bau Bines Oberdrucks von diesem untergriffen werden . Ande-
`rerseits baut sick auf der von dem Fahrtwind abgewandten
`
`Rackseite wegen der erwahnten Bauform ein erheblicher Unter-
`druck auf . Zwar verandert das im Betrieb meist eine Pendel-
`bewegung ausfiahrende Wischblatt seine Lage in bezug auf den
`anstromenden Fahrtwind standig, doch ist auch dann stets
`
`5
`
`10
`
`15
`
`seine eine Langsseite diesem mehr oder weniger stark zuge-
`wandt and wird deshalb auch als Vorderseite bezeichnet, wah-
`rend seine andere Langsseite demzufolge auch als Ruckseite
`angesehen wird . zm Zusammenwirken dieser beiden vorerwahnten
`Drucke, die beide dem Wischblatt-AnpreZdruck entgegengerich-
`tet Sind, wird dieser bei hoheren Fahrgeschwindigkeiten zu-
`mindest so verringert, dag kein ordnungsgema ges Wischergeb-
`nis mehr moglich ist . Eine Verstarkung des Wischblatt-
`Anpre9drucks gegen die Scheibe mag bei hohen Fahrgeschwin-
`20 digkeiten zwar dieses Problem verkleinern, doch bei geringe-
`ren Fahrgeschwindigkeiten, wenn das Abhebebestreben verrin-
`
`gert wird, erhoht sick aber die Reibung zwischen Wischblatt
`and Scheibe, was zu einer unerwanschten Gerauschbildung un .d
`zur unzulassig hohen Belastung der Antriebskomponenten
`fuhrt.
`
`Vorteile der Erfindung
`
`Bei dem erfin.dungsgemaZen Wischblatt mit den kennzeichnenden
`Merkmalen des Anspruchs 1 wird Ober die dem Fahrtwind zuge-
`wandte Anstromflache eine zur Scheibe gerichtete Kraftkompo-
`nente aufgebaut, welche dem Abhebebestreben der beiden Druk-
`ke entgegenwirkt and so fur eine hervorragende Reinigungs--
`qualitat im fur den Fahrzeuglenker wichtigen Bereich des vom
`Wischblatt Oberstrichenen Wischfeldes sorgt . Je nach Gr6ge

`
`der Anstromflache and/oder je nach GrMe des Anstellwinkels
`a kann dieser Hilfs-Anlegedruck den veranderlichen, vom
`Fahrzeugtyp abhangigen Forderungen angepafSt werden . Weiter
`ist bei der erfindungsgemaiSen Lbsung von Vorteil, daZ der
`AnpreiSdruck als Funktion der Fahrgeschwindigkeit mit dieser
`ansteigt oder abfallt . Es wird also nur dem bei grazer Ge-
`schwindigkeit auftretenden storenden Abhe
