    [0001] Field of the Invention The present invention relates to a wiper arm device having a wiper arm unit having at least one wiper rod and at least one nozzle unit for applying apply washing water to the vehicle window and which is at least essentially installed on the side of the wiper arm unit. STATE OF THE ART According to the document EP 1 985 513 A 1, a wiper arm device is known comprising a windscreen wiper arm unit equipped with a windscreen wiper rod as well as a windscreen wiper arm unit. a nozzle unit for applying washing water to a window of the vehicle. The nozzle unit according to a development is located in the substantially laterally installed state with respect to the wiper arm unit. DESCRIPTION AND ADVANTAGES OF THE INVENTION The subject of the invention is a wiper arm device of the type defined above, characterized in that the nozzle unit in the installed state is at least essentially in the extension of the wiper rod of the wiper arm unit and is fixed by a snap connection to the wiper arm unit.
    [0002] Preferably, the nozzle unit in the installed state is at least substantially adjacent to the wiper arm adapter of the wiper arm unit. The wiper arm unit according to the invention is a unit composed of a windscreen wiper rod and / or a wiper arm adapter and / or a wiper arm connection. drive shaft and preferably it is in the form of a wiper rod and / or a wiper arm adapter. The wiper arm adapter according to the invention is an adapter having a contact region for the wiper rod to thereby provide a coupling region of the wiper rod for coupling and / or or contacting a wiper blade, particularly the wiper blade adapter. Preferably, the wiper arm adapter of the windscreen wiper arm unit is constituted in particular by a "Top-Lock" wiper arm adapter, that is to say locking from above. The connection of the drive shaft according to the invention corresponds to a connection piece of the wiper arm to be connected to the drive shaft of an engine and produce the wiping movement around the wiper arm. a center of rotation. The nozzle unit according to the invention is a unit comprising at least one nozzle element for applying wash water to the vehicle window. The nozzle element is an element applying the wash water and preferably spraying this water in a certain direction. In particular, the nozzle element has a nozzle orifice from which the washing water supply system opens. The nozzle member may be metal and / or preferably a plastics material. The nozzle unit is in particular connected directly to the wiper arm unit. The direct link according to the invention is a direct application link. The term "intended for" used under certain conditions in the description means that it is a means specially designed and / or equipped to perform a certain function. Since an object is provided for a certain function, this means that this object responds to this function determined in at least one application and / or operating state. The washing water according to the invention is a washing liquid and / or cleaning the vehicle glass, in particular water, alcohol or a mixture comprising a part of water, a part of agent antifreeze and / or a part of alcohol. The fact that at least one nozzle unit in the installed state is "at least substantially laterally" on the wiper arm unit means in particular that at least one nozzle unit in the state installed, viewed in a direction perpendicular to the vehicle window is essentially adjacent to the wiper arm unit. This means that according to a two-dimensional consideration, when viewed in the direction perpendicular to the vehicle window, there is a region of overlap between the nozzle unit and the wiper arm unit which is less 30%, preferably less than 20% and particularly preferably less than 10% of the visible area of the nozzle unit and / or the wiper arm unit. This preferably means that at least 20%, preferably at least 40% and particularly preferably at least 60% of all the planes which are parallel to the vehicle window in the region of the nozzle unit and that cut the nozzle unit, also cut the wiper arm unit. More preferably, this means that the smallest angle between a plane parallel to the vehicle window in the region of at least one nozzle unit and a line intersecting the geometric center of the nozzle unit and the center the wiper arm unit geometrical angle is at least less than 50 ° and preferably less than 40 ° and particularly preferably less than 30 °. The fact that at least one nozzle unit in the installed state is "at least essentially in the extension" of a rod of the wiper unit means in particular that the straight line which is parallel to the main direction of extension of the wiper rod of the wiper arm unit and passing through the geometric center of the wiper rod, cuts the nozzle unit when this is in the installed state. This preferably means that the main direction of extension of the nozzle unit in the installed state is at least substantially parallel to the main direction of extension of the windscreen wiper rod of the arm unit. wiper. The main direction of extension of an element and / or a component is in particular the direction parallel to the largest edge of the smallest geometrical cube completely enveloping the element and / or the component.
    [0003] In addition, the fact that a straight line is at least substantially parallel means that the parallelism defect is at most equal to 20 °, preferably at most 15 ° and in a particularly preferential manner, at most equal to 10 °. . The expression "snap connection" means in particular that it is a connection between two clipping units. Preferably, it is a connection in which at least one clipping means of a first clipping unit enters an engagement cavity of a second clipping unit. The clipping means in this context designates in particular an elastic element for making the connection by clipping and deform elastically mounting.
    [0004] A suitable embodiment of the windscreen wiper arm device makes it possible in particular to provide an advantageous nozzle unit. In particular, the assembly allows an advantageous distribution of the washing liquid. In addition, there will be an advantageously reliable connection of the nozzle unit to the wiper arm unit. This results in particular in an advantageously aerodynamic arrangement of the nozzle unit. According to another feature, the nozzle unit in the installed state is at least substantially and preferably completely outside the blank of the wiper arm unit. The blank in this context refers in particular to a side wall or skirt of the wiper arm unit, bent with respect to the upper side of the wiper arm at least substantially orthogonally. that is at an angle of at least 75 ° and preferably at least 80 ° and particularly preferably at least 85 ° with respect to the upper side of the wiper arm. ice cream. In particular, two opposite blanks and the upper side of the wiper arm unit form a profile having essentially a section U. The fact that at least one nozzle unit in the installed state is "at least for most of the outside of a blank of the wiper arm unit means that the nozzle unit, starting from the geometric center of the wiper arm unit, is at least mostly behind a blank of the wiper arm unit. This means in particular that the nozzle unit is at least essentially on one side opposite the blank. In particular, this means that at least 50% and preferably at least 70% and particularly preferably at least 90% of the nozzle unit in the installed state are outside the blank of the nozzle. wiper arm unit. This leads to an advantageously simple mounting of the nozzle unit. In addition, there will be an advantageous arrangement of the nozzle unit on the wiper arm unit.
    [0005] Advantageously, the nozzle unit is installed on the wiper arm unit by a movement oriented in the wiping direction. The wiping direction is in particular the direction in which the wiper arm unit, in the operating state, passes over the wiping window. Preferably, this is in particular a direction in which the wiper arm unit in operation sweeps through the wiper blade on the vehicle window. Preferably, the wiping direction is in particular substantially perpendicular to the main direction of extension of the wiper rod. In a particularly preferred manner, the wiping direction is defined in particular as a direction of movement of the wiper arm unit for its upward movement and also for its downward movement. Since the nozzle unit is mounted on the wiper arm unit at least by a movement in the wiping direction, this means that the nozzle unit must be moved at least partially in one direction to the other. less substantially parallel to the wiping direction for mounting on the wiper arm unit. Preferably, this means in particular that for its mounting on the wiper arm unit, the nozzle unit must be moved at least substantially parallel to the wiping direction, in the direction of the wiper unit. windshield wiper arm to make the connection by clipping. This ensures the safety of mounting the nozzle unit on the wiper arm unit. Preferably, it avoids in particular any accidental detachment of the nozzle unit. In addition, this corresponds to a particularly simple and practical assembly. According to a preferred development of the invention, the wiper arm unit comprises at least a first substantially rigid retaining element on which the nozzle unit is mounted.
    [0006] The at least essentially rigid element is an element that is practically motionless relative to itself throughout its extension. Preferably, this corresponds in particular to an element which, during operation, remains rigid even under the effect of a certain solicitation. Preferably, it is an element which, in normal operation, and under a load of at least 1 N and preferably at least 5 N and in a particularly preferential manner under the effect of a stress of at least 10 N is elastically deformed over its entire extension by less than 2 mm and preferably less than 1 mm and particularly preferably by less than 0.5 mm. It is in particular an element which, under the effect of a static bending stress, has a limiting tension of at least 100 N / mm 2 and preferably at least 200 N / mm 2 and in a manner particularly preferred, of at least 300 N / mm 2. This provides a particularly reliable attachment of the nozzle unit to the wiper arm unit. This allows in particular to have a preferably solid retention element. According to another characteristic, the first element is provided on the front face of the wiper arm unit. The front face of the wiper arm unit represents in this context in particular the free end of the wiper arm unit opposite the connection of the drive shaft and or the center of rotation of the wiper arm unit. Preferably, this includes the free end of the wiper arm adapter. If at least the first retaining element is provided on a front face of the wiper arm unit, a particularly advantageous disposition of at least one first retaining element will be provided. In addition, this guarantees the safety of the holding of the nozzle unit on the wiper arm unit. According to another characteristic, at least the first retaining element is constituted by a first tab oriented in the wiping direction. In this context, the leg is in particular an extension-shaped element. This is preferably an element that is at least partially protruding from the basic shape of the wiper arm unit. Particularly preferred is an element having a substantially rectangular base shape which projects from the base form of the wiper arm unit at least in one direction. substantially perpendicular. There is thus a particularly advantageous retention element. This allows a conveniently simple attachment of the nozzle unit. Advantageously, the first retaining element comprises at least one retaining hook for fixing the nozzle unit. A retaining hook within the meaning of the present invention is an element and / or part of an element which must prevent the nozzle unit from detaching from the retaining element. Preferably, it includes an element and / or part of an element provided to block any movement of the nozzle unit in the state opposite to the mounting direction. Preferably, it is in particular an element and / or a part of an element which, considered in the mounting direction of the nozzle unit forms at least partly an undercut area. In a particularly preferred manner, the element and / or the part of the element have an abutment surface inclined with respect to the mounting direction of at least 70.degree. And preferably at least 80.degree. a particularly preferred manner of at least 90 °. This makes it possible to have a reliable holding of the nozzle unit on the wiper arm unit. In addition, the accidental detachment of the nozzle unit is thus safely avoided. This avoids, in particular, that the nozzle unit can not be detached from the wiper arm unit without being damaged.
    [0007] According to a particularly preferred development of the invention, the wiper arm unit comprises at least a second essentially rigid retaining element for fixing the nozzle unit in the installed state. This allows in particular a reliable holding of the nozzle unit. In particular, there will be an advantageously reliable positioning of the nozzle unit assembly. If at least the second retaining element is spaced from the end face of the wiper arm unit, there will be a particularly reliable holding of the nozzle unit. In a particularly preferred manner, the positioning of the nozzle unit is thus advantageously achieved. Preferably, the second retaining element is spaced from the front face of the nozzle arm unit by at least 0.5 cm, preferably at least 1 cm, and in a particularly preferred manner. at least 3 cm. Preferably, the second retaining element is spaced apart in the direction of the drive shaft connection and / or the center of rotation of the wiper arm unit with respect to the front face of the unit. wiper arm. According to another characteristic, the second retaining element is constituted by a second tab oriented in the wiping direction. Preferably, the second retainer protrudes from the base shape of the wiper arm unit in the wiping direction. This makes it possible to have particularly advantageous retention elements. In addition, there will be a particularly reliable behavior of the nozzle unit.
    [0008] According to a development of the invention, at least one second retaining element has at least one retaining hook for fixing the nozzle unit. This provides a particularly reliable hold of the nozzle unit on the wiper arm unit. In addition, any accidental detachment of the nozzle unit is safely avoided.
    [0009] In particular, this prevents the nozzle unit from being detached from the wiper arm unit without being damaged. According to another development of the invention, the second retaining element comprises at least one fixing cavity for receiving a fixing element for fixing the nozzle unit. The fixing cavity is a recessed portion or a through hole for at least partially receiving a fastener for attachment. Preferably, it is a recessed portion or a recess or through cavity, to ensure the attachment of a fastener. In a particularly preferred manner, the fixing cavity is constituted in particular by a through orifice for fixing the nozzle unit on the second retaining element with the aid of a fixing element, and this in particular in that the latter completely through this recess. The fastening element is an element intended to cooperate with a corresponding fastening element to make a connection and / or to penetrate into the cavity or fixing recess to form a connection. Preferably, the element according to the present invention, is an element for making a connection by the shape and / or force with a corresponding fastening element and / or a corresponding fixing cavity or recess. Various fastening elements of interest, such as, for example, screws, rivets and / or particularly preferably extensions or projecting parts for clipping, can technically be envisaged. In this way a particularly reliable resistance of the nozzle unit to the windscreen wiper arm unit is achieved. In addition, this fixing is done in a particularly simple and reliable manner.
    [0010] According to another characteristic, the main extension plane of the first retaining element and the main extension plane of the second retaining element form in them at least an angle substantially equal to 90 °. The main extension plane of an object according to the present invention is a plane parallel to the largest lateral surface of the smallest geometrical cube completely enveloping the object and in particular passing through the center of the cube. This results in a particularly reliable attachment and advantageously avoid accidental detachment that would occur easily.
    [0011] According to another feature, the nozzle unit has at least a first cavity for receiving a first retainer. Preferably, this first cavity is made correspondingly and preferably at least substantially in a manner adjusted to the first retaining element, which allows a conveniently simple and fast mounting of the nozzle unit. In addition, this advantageously guarantees the holding of the nozzle unit on the first retaining element. According to a development of the invention, the nozzle unit has a second cavity for receiving a second retaining member. Preferably this second cavity is correspondingly formed and preferably at least substantially fitted to the second retaining element, which allows a particularly simple and rapid mounting of the nozzle unit. In addition, there is particularly advantageous holding of the nozzle unit on the second retaining element.
    [0012] According to another feature, the nozzle unit has a first spring member which in the installed state is hooked to a second retainer. The spring element represents in the present context a macroscopic element which has an extension which in the normal operating state can vary elastically by at least 10% and especially by at least 20% and preferably by at least 30% and particularly advantageously at least 50% and which opposes an antagonistic force to this variation and depends on this variation, and preferably proportional thereto. The extension of an element according to the present invention relates in particular to the length of an edge of the smallest geometrical cube which still completely envelops the object. A macroscopic element according to the invention is an element having an extension of at least 1 mm and in particular of at least 2 mm and preferably of at least 4 mm. This makes it possible to have a particularly secure hold of the nozzle unit at least with respect to the first retaining element. Preferably, the first spring element is housed in at least a first cavity which advantageously protects this first spring element. In addition, the nozzle unit has at least one second spring element preferably housed in a second cavity or recess.
    [0013] According to another feature, the nozzle unit comprises at least two first spring members between which a first retention member is engaged in the installed state. This allows in particular to ensure the holding of the nozzle unit at least on the first retaining element. In addition, it avoids safely accidental detachment. Preferably, at least two first spring elements are provided in a first cavity which advantageously protects the first spring elements. According to another development of the invention, the nozzle unit comprises a fixing element formed in particular in one piece with the nozzle unit and which, in the installed state, is in at least one fixing cavity. This fastening element may be a stud and / or a fastening element, in particular a fastening stud. An attachment pin according to the present invention is a stud-shaped member. Preferably, it is in particular a fastening element having at least substantially a cylindrical base shape. Particularly preferably, this designates in particular a fastening element having at least substantially a cylindrical base shape and its outer surface, in particular the surface encompassing the base shape, comprises clipping means. This makes it possible to have a particularly safe and reliable behavior of the nozzle unit in the fixing cavity. In addition, it avoids safely, accidental detachment. Advantageously, the nozzle unit in the installed state is in the wiper arm adapter region of the wiper arm unit. The wiper arm adapter region is in the present context including an area around the wiper arm adapter. Preferably, the wiper arm adapter region or region is the end face of the wiper arm unit. In particular, the wiper arm adapter region extends in a region at a distance from the wiper arm adapter and / or the front face of the wiper arm unit. wiper which is less than 20 cm, especially less than 15 cm and preferably less than 10 cm and particularly preferably less than 5 cm. This results in a particularly advantageous arrangement of the nozzle unit. Preferably, an arrangement is thus made, in particular an advantageous distribution of the wiping liquid. According to another feature, the nozzle unit in the installed state is attached to the wiper arm adapter of the wiper arm unit. The wiper arm adapter includes a Side-Lock wiper arm adapter (side-lock) and particularly advantageously is a wiper arm adapter. -glace Top-Lock (adapter from above). There is thus a particularly advantageous mounting of the nozzle unit. Preferably, the device allows an advantageous distribution of the washing liquid. The wiper arm device according to the invention is not limited to the above application and embodiment.

    [0014] DESCRIPTION OF EMBODIMENTS FIG. 1 shows a wiper arm device having a wiper arm unit 10a and a nozzle unit 14a. The windshield wiper arm device is shown partly broken away or in the process of being mounted in FIG. 1. The wiper arm device is part of a windshield wiper arm. The wiper arm unit 10a comprises a wiper rod 12a. In addition, the wiper arm unit 10a includes a wiper arm adapter 44a. This wiper arm adapter 44a is a top lock adapter. The wiper arm adapter 44a is provided to receive the adapter of a wiper blade not shown.
    [0015] The wiper blade adapter is thus housed in the wiper arm adapter 44a. In addition, the wiper arm adapter 44a is in one piece with the wiper rod 12a of the wiper arm unit 10a. The wiper rod 12a has a main extension direction 46a which substantially corresponds to the main extension direction 48a of the wiper arm adapter 44a. The wiper arm adapter 44a considered parallel to its main extension direction 48a has a length of between 4 cm and 6 cm. The wiper arm adapter 44a has, parallel to its main extension direction 48a, a length of about 5 cm. The wiper arm adapter 44a has in a plane perpendicular to the main extension direction 48a, a substantially U-shaped section. The two sides of this U-shaped section consist of the flanks 16a, 50a of the wiper arm unit 10a. The two sides of the U-shaped section consist of the flanks 16a, 50a of the wiper arm adapter 44a. The flanks 16a, 50a have a height of between 1 cm and 2 cm in a direction perpendicular to the main extension direction 48a of the wiper arm adapter 44a. The flanks 16a, 50a have in the direction perpendicular to the main extension direction 48a of the wiper arm adapter 44a, a height of about 1.2 cm. In addition, the flanks 16a, 50a have in the direction perpendicular to the main extension direction 48a of the wiper arm adapter 44a and perpendicular to the main extension plane of the flanks 16a, 50a, including a gap between 1 cm and 2 cm. The flanks 16a, 50a considered perpendicular to the main extension direction 48a of the wiper arm adapter 44a and in the direction perpendicular to the main plane of extension of the flanks 16a, 50a, have a gap close to 1 , 6 cm. In principle, one could also consider another technically interesting dimensioning of the wiper arm adapter 44a. The flanks 16a, 50a are connected by the base side 52a of the wiper arm adapter 44a. The base side 52a forms the top of the wiper arm adapter 44a. The flanks 16a, 50a join the base side 52a by a leave. The fillet (radius) is between 0.1 cm and 0.5 cm. The leave is close to 0.3 cm. But in principle one could also consider another technically interesting radius. The free ends of the sidewalls 16a, 50a of the wiper arm adapter 44a, away from the base side 52a, each have guide rails for guiding and securing a wiper blade adapter. in the wiper arm adapter 44a. The guide rails are in one piece with the flanks 16a, 50a. Flanks 16a, 50a each join the guide rails through a leave. The leave is between 0.1 cm and 0.3 cm. The radius is around 0.2 cm. In principle one can also consider another technically interesting holiday. The wiper arm adapter 44a is in one piece formed from a bent metal plate. In principle, one could also consider an embodiment in several parts and / or in another material of technical interest (Figures 2, 3). In addition, the wiper arm unit 10a includes a first substantially rigid retainer 20a. In the installed state, the nozzle unit 14a is attached to the first retainer member 20a. The first retainer 20a is provided on a front side 22a of the wiper arm unit 10a. The first retainer 20a is installed on the first front side 22a of the wiper arm adapter 44a. The first retainer 20a forms part of the end face 22a of the wiper arm unit 10a. The first retaining element 20a is constituted by a first tab 24a which deviates from the wiping direction 18a. The first retaining element 20a has, in the wiping direction 18a, a length of between 0.5 cm and 1.5 cm. The first fastening element 20a has in the wiping direction 18a, a length close to 1 cm. But in principle, one could also consider another technically interesting length. The wiper direction 18a extends perpendicularly to the main extension direction 48a of the wiper arm adapter 44a and perpendicular to the main extension plane of the sidewall 16a.
    [0016] The first retainer 20a has a major extension plane perpendicular to the main extension direction 48a of the wiper arm adapter 44a and perpendicular to the main extension plane of the sidewall 16a.

Directly behind the retaining hook 26a, the base body of the first retaining member 20a has a narrowed or thinned partial region. This narrowed partial region allows snapping. In principle, one could also consider a base body of the first retaining element 20a having a constant section. The first retainer 20a is directly adjacent to the sidewall 16a of the wiper arm unit 10a. The first retainer 20a protrudes in the direction perpendicular to the sidewall 16a with respect to the wiper arm adapter 44a. In addition, the first retainer 20a is made in one piece with the wiper arm adapter 44a. The first retainer 20a is bent in common with the wiper arm adapter 44a from a metal plate. But in principle, one could also consider another technically interesting material and / or another embodiment separate from the wiper arm adapter 44a. In principle, it would also be possible to install the first retaining element 20a posteriorly on the wiper arm adapter 44a (FIGS. 1, 2). In addition, the wiper arm unit 10a has a second substantially rigid retainer 28a. In the installed state, the nozzle unit 14a is attached to the second retainer 28a.

The second retaining element 28a considered parallel to the main extension direction 48a of the wiper arm adapter 44a is spaced apart from the first retaining element 20a by a distance of between 3 cm and 5 cm. The second retaining element 28a considered parallel to the main extension direction 48a of the wiper arm adapter 44a is spaced from the first retaining element 20a by about 3.5 cm. But in principle we could also consider another technically interesting gauge. The second retainer 28a is at the free end opposite the base side 52a of the sidewall 16a of the wiper arm adapter 44a. The second retainer 28a is on the side of the flank 16a opposite one of the guide rails. The second retainer 28a is directly adjacent to the sidewall 16a of the wiper arm unit 10a.

The second retaining element 28a has a length in the wiping direction 18a of between 0.5 cm and 1.5 cm. The second retaining element 28a has in the wiping direction 18a, a length close to 0.8 cm. But in principle we could also consider another technically interesting length. The second retainer 28a has a main extension plane extending parallel to the main extension direction 48a of the wiper arm adapter 44a and perpendicular to the main extension plane of the sidewall 16a.

The fixing cavity 34a extends perpendicularly to the main extension direction 48a of the wiper arm adapter 44a and parallel to the main extension plane of the sidewall 16a in the material of the second leg 30a. In addition, the first retainer 20a is made in one piece with the wiper arm adapter 44a. The first retainer 20a is formed in common with the wiper arm adapter 44a in a metal plate. But in principle, one could also consider another technically interesting material and / or another embodiment separate from the wiper arm adapter 44a. In principle, it could also be envisaged to make the first retaining element 20a posteriorly on a wiper arm adapter 44a (FIGS. 1, 2). The main plane of extension of the first retaining element 20a and the extension plane of the second retaining element 28a form between them an angle substantially equal to 90 °. The main plane of extension of the first retaining element 20a and the main plane of extension of the second retaining element 28a form between them an angle of 90 ° (FIG. 2). The wiper arm device has a nozzle unit 14a. The nozzle unit 14a makes it possible to apply washing water to the window of the vehicle. The nozzle unit 14a in the operating state receives wash water through a non-visible wash pipe connected to the nozzle unit 14a; this makes it possible to distribute the washing water on the window of the vehicle. For this purpose, the nozzle unit 14a has a plurality of wiping nozzles 54a. In principle, one could also consider a nozzle unit 14a with a single wiper nozzle 54a. The wiping nozzles 54a have in the installed state of the nozzle unit 14a, each of the projection directions facing towards the vehicle window. The nozzle unit 14a also has a connection nozzle 56a for the wash water pipe. The connecting nozzle 56a in the main extension direction of the nozzle unit 14a is located at the rear end of the nozzle unit 14a, away from the wiping nozzles 54a. In the installed state of the nozzle unit 14a, the branch nozzle 56a is on the side of the nozzle unit 14a facing the rod 12a of the wiper arm unit 10a. This advantageously allows the washing water pipe to be guided along the wiper rod 12a to the nozzle unit 14a (FIG. 1). In the installed state, the nozzle unit 14a is substantially adjacent to the wiper arm unit 10a. The nozzle unit 14a in the installed state is in a wiper arm adapter region 42a of the wiper arm unit 10a. The nozzle unit 14a in the installed state is on the wiper arm adapter 44a of the wiper arm unit 10a. In the installed state, the nozzle unit 14a is substantially adjacent to the wiper arm adapter 44a of the wiper arm unit 10a. In addition, in the installed state, the nozzle unit 14a is substantially in the extension of the wiper rod 12a of the wiper arm unit 10a. The main extension direction 46a of the wiper rod 12a is responsive parallel to the main direction of extension of the nozzle unit 14a. A line parallel to the main extension direction 46a of the wiper rod 12a intersects the geometric center of the wiper rod 12a by cutting the nozzle unit 14a in the installed state. The nozzle unit 14a in the installed state is outside the side 16a of the wiper arm adapter 44a of the wiper arm unit 10a (FIG. 1).
    [0018] In addition, in the installed state, the nozzle unit 14a is attached to the wiper arm unit 10a by a snap connection. The nozzle unit 14a has a first recess 36a for receiving the first retainer 20a of the wiper arm unit 10a. The first retainer 20a, in the mounted state of the nozzle unit 14a, is housed in the first recess 36a of the nozzle unit 14a. The nozzle unit 14a has two first spring members 38a, 40a which, in the mounted state, hook onto the first retainer member 20a. The first retainer 20a snaps into the installed state of the nozzle unit 14a between the two first spring members 38a, 40a. The first two spring members 38a, 40a are in the recess 36a of the nozzle unit 14a. The first two spring elements 38a, 40a are respectively constituted by elastic branches penetrating into the cavity 36a. As the first two elastic members 38a, 40a reduce the recess 36a in a direction oriented in the recess 36a. The first two spring members 38a, 40a join substantially in a conical pattern in the direction toward the recess 36a. The first two spring members 38a, 40a are substantially non-contact. In addition, the depth of the recess 36a is greater than the length of the first two spring members 38a, 40a so that the retaining hooks 26a of the first retaining member 20a, in the installed state of the nozzle unit 14a are in the cavity 36a behind the first two spring members 38a, 40a. The spring elements 38a, 40a are thereby deformed when the nozzle unit 14a is mounted by the first retaining element 20a, being elastically deflected outwards and then hooked behind the retaining hooks 26a. the first retainer 20a (Figures 1, 3, 4). In addition, the nozzle unit 14a has a fastener 35a. The fixing member 35a, in the installed state, is housed in the fastening cavity 34a of the second retaining element 28a. The fastening element 35a is constituted by a locking pin. The fixing element 35a comprises two semicylindrical basic bodies slightly spaced apart from each other. The free end of the base bodies has a respective peripheral latching nose on the envelope surface of the base body. The hooking lugs of the fastener 35a, in the installed state of the nozzle unit 14a, are provided to hook behind the fastening cavity 34a. The latching beaks thus cling behind the fixing cavity 34a so that a portion of the two semi-cylindrical base bodies are housed in the fixing cavity 34a and the remainder of the nozzle unit 14a is located. on the side of the mounting recess 34a opposite that of the latching slats. Due to the slight spacing of the base bodies of the fastening element 35a one can move away from one another to the base bodies elastically as a spring during assembly so that the snap jaws can pass in the fixing recess 34a (Figures 1 and 5). The nozzle unit 14a is moved by a motion applied to the wiper arm unit 10a oriented in the wiping direction 18a. For assembly, the nozzle unit 14a is slid by a movement directed in the wiping direction 18a against the side 16a of the wiper arm unit 10a so that the first retention member 20a of the wiper arm unit 10a is engaged in the first cavity 36a of the nozzle unit 14a. Next, the nozzle unit 14a is rotated about an axis constituted by the first fastening element 20a, perpendicularly to the lateral flank 16a so that the fastening element 35a of the nozzle unit 14a clings. in the fixing cavity 34a of the wiper arm unit 10a. In the next step, the wiper water pipe, which is not visible, is connected to the connection nozzle 56a of the nozzle unit 14a. Figures 6 to 16 show further exemplary embodiments of the invention.

The first retainer 20b has a retaining hook 26b for attaching the nozzle unit. The hook 26b is constituted by a spout protruding from the base body of the first retaining element 20b. The retaining hook 26b protrudes in the direction perpendicular to the main extension direction 48b of the wiper arm adapter 44b and parallel to the main extension plane of the sidewall 16b from the base body of the wiper arm adapter 44b. first retaining element 20b. In addition, the nozzle unit, in the installed state, is fixed by a snap connection to the wiper arm unit 10b. The nozzle unit has a first cavity for receiving the first retainer member 20b of the wiper arm unit 10b. The first retainer member 20b, in the mounted state of the nozzle unit, is housed in the first recess or first cavity of the nozzle unit. The nozzle unit has a first spring member which in the installed state is hooked to the first retainer member 20b. The first spring element is housed in the cavity of the nozzle unit. The spring element is constituted by an elastic spacer as a spring projecting into the cavity. The spring element reduces the cavity in the direction towards the cavity. The retaining hook 26b of the first retaining member 20b snaps into the installed state of the nozzle unit into the cavity behind the first spring member.
    [0020] Figure 7 shows a wiper arm unit 10c corresponding to an alternative embodiment of the wiper arm device with a first substantially rigid retainer 20c and a second substantially rigid retainer 28c.
    [0021] A nozzle unit 14c is fixed in the installed state on the first retainer 20c. The first retaining element 20c consists of a first tab 24c facing away from the windscreen wiper device 18c. The first retainer 20c has two retaining hooks 26c for attaching the nozzle unit 14c. The hooks 26c consist of projecting spouts respectively on the opposite sides starting from the base body of the first retaining element 20c. The retaining hooks 26c each project perpendicularly to the main extension direction 48c of the wiper arm adapter 44c and parallel to the main extension plane of the sidewall 16c from the base body of the first element. retainer 20c. The base body of the first retainer 20c has a constant section. In the mounted state, the nozzle unit 14c is attached to the first retaining member 20c and the second retaining member 28c. The second retaining element 28c consists of one of the two tabs 30c turned in the wiping direction 18c. The second retaining element 28c has, in the wiping direction 18c, a length of between 0.5 cm and 1.5 cm. The second retaining element 28c has along the wiping direction 18c, a length of about 1 cm. In principle, however, another technically interesting length could be envisaged. The second retainer 28c has a curved partial region 58c and a narrowed partial region 60c. Partial regions 58c, 60c serve to secure the bus unit 14c. The curved partial region 58c is at the free end of the second retaining element 28c. The detailed partial area 60c is provided at a fixed end of the second retention member 28c. The cut partial region 60c directly joins the curved partial region 58c. The narrowed partial region 60c makes it possible to guarantee the attachment (FIG. 8). In the installed state, the nozzle unit 14c is attached to the wiping arm unit 10c by a snap connection. The nozzle unit 14c has a first cavity for receiving the first retaining member 20c of the wiper arm unit 10c. In addition, the nozzle unit 14c has a second cavity 37c for receiving the second retainer 28c. The second retainer 28c is housed in the second cavity 37c of the nozzle unit 14c when this unit 14c is in the mounted state. The nozzle unit 14c has two spring members 62c, 64c which, in the mounted state, hook onto the second retainer 28c. In the mounted state, the second retainer 28c clings between the two spring members 62c, 64c. The two spring members 62c, 64c are in the second cavity 37c of the nozzle unit 14c.
    [0022] The two second spring elements 62c, 64c are respectively formed by large elastics provided with bulging reliefs in the cavity 37c. The two spring members 62c, 64c partially reduce the cavity 37c. The curved extensions of the two second spring members 62c, 64c are rotated towards each other and protrude in the middle of the cavity 37c. The curved extensions of the two second spring members 62c, 64c are intended to engage in the narrowed partial region 60c of the second retainer 28c. The spring elements 62c, 64c are therefore elastically outwardly dedicated to the mounting of the nozzle unit 14c by the curved partial region 58c to then engage in the reduced partial region 60c of the second retaining element 28c (FIG. 8). The nozzle unit 14c is mounted on the wiper arm unit 10c by a movement directed in the wiping direction 18c.

Figure 9 shows a wiper arm unit 10d of another wiper arm device variant with a first substantially rigid retainer 20d and a second substantially rigid retainer 28d. A nozzle unit is fixed in the installed state on the first retainer 20d. The first retaining element 20d is formed by a first tab 24d oriented in the wiping direction 18d. The first retainer 20d has four retainer hooks 26d for blocking the nozzle unit. In principle, one could also consider a different number of retaining hooks 26d. The retaining hooks 26d are each formed by a spout and in each case two such hooks are provided on the opposite projecting sides of the base body of the first retaining element 20d. The retaining hooks 26d respectively protrude perpendicularly to the main extension direction 48d of the wiper arm adapter 44d and parallel to the main extension plane of the side wall 16d projecting from the base body of the wiper arm adapter 44d. first retainer 20d. On each side of the base body of the first retainer 20d there are two retaining hooks 26d. The two retaining hooks 26d on one side are one behind the other, considered in a direction perpendicular to the main extension plane of the sidewall 16d. The different retaining hooks 26d allow a particularly reliable hooking even in different positions.
