    Field of the invention
    The present invention relates to a deflector unit, in particular a wiper arm deflector unit comprising a deflector element.
    State of the art
    Already known are such units for windscreen wiper deflectors.
    Presentation and advantages of the invention
    The subject of the present invention is a deflector unit, in particular a wiper arm deflector unit comprising at least one deflector element with at least a first coupling unit which, in the installed state, are connected to the rod of a wiper arm and having at least a second coupling unit which in the installed state receives a channel of washing liquid.
    According to the invention, the deflector element is designed to deflect the circulating wind exerted on the wiper arm device and / or to press this wiper arm device against the arm which carries it. Preferably, the deflector element has at least one concave outer surface.
    The coupling unit makes the connection, in particular a removable connection without destruction. The unit is intended to connect the wiper arm unit by a form connection, a force connection and / or a material connection to the rod of the wiper arm and / or a washing liquid channel.
    In a particularly preferential manner, the unit makes it possible to make a non-destructive connection and this connection is made in particular without requiring any tool.
    The expression "intended for", if applicable, used in the description means that it is a means specially designed, designed and / or programmed or equipped to perform a certain function. The fact that an object is provided to perform a certain function means in particular that the object performs this function in a certain state of application and / or operation.
    The wiper rod is an elongated part of the wiper arm that extends at least substantially parallel to the main direction of extension of the wiper arm. The part connects the drive axis of the wiper arm indirectly to a region for receiving the wiper blade to transmit the movement, in particular a rotational movement. The washing liquid channel is a channel which connects, in particular in a partial segment, the washing liquid in an operating state to the washing distribution or distribution unit, in particular from a reservoir to the washing. Preferably, it is a channel which is provided in at least one partial segment for receiving washing liquid from a pipe and / or from a transfer means. In particular, it is a channel which allows at least in a certain operating state to receive washing liquid.
    The realization of the deflector unit according to the invention notably prevents any accidental unwanted detachment of the deflector unit. In particular, this prevents any current detachment from the deflector unit, for example, that which could be produced by the circulating wind.
    According to another characteristic, the deflector element is in one piece with a first coupling unit and / or with at least a second coupling unit. It is preferably at least one deflector element of the first coupling unit and of the second coupling unit in one piece. The expression “in one piece” means in particular that it is a connection at least by the material, for example a connection produced by welding, a connection produced by gluing or a connection produced by an overmolding process by injection and / or other technically advantageous process and / or under a part advantageously produced in a single piece such as for example a manufacture with a cast iron and / or a manufacture according to an injection process with one or more components and also of advantageously an embodiment from a single blank.
    The production in a single piece designates in particular a preferred production by a transformation process. This advantageously makes it possible to have a deflector unit, the number of components of which is reduced to a minimum, which allows particularly advantageous, simple and rapid assembly.
    According to another characteristic, the first coupling unit and the second coupling unit comprises a clip-on fixing element. A clip fastening element constitutes an element provided with clipping means. The means of clipping or hooking allows both hooking with the fixing element itself and / or with a part to be associated. The attachment or clipping means designates in particular an elastic means such as a spring for making a connection by clipping and which is elastically deformed during assembly. This allows deflector units to be installed which are particularly easy to install. In particular, this allows for an extremely simple coupling. In particular, you can simply clip the deflector unit onto the wiper arm. This allows a particularly simple and quick retrofit installation of the deflector unit on a wiper arm. It is just as easy to clip a washing liquid channel onto the deflector unit. In particular, this allows a simple and quick retrofitting of a washing liquid channel by the deflector unit on a wiper arm.
    According to another characteristic, the first coupling unit or the second coupling unit comprises a clip-on fixing element, which constitutes a deflector unit which is particularly simple to install. This allows for advantageously simple coupling. The deflector unit can be easily clipped onto the wiper arm, as is the wash fluid channel. Overall, this allows a very simple and quick retrofitting of a deflector unit on a wiper arm.
    According to another characteristic, the first coupling unit and the second coupling unit each have a receiving region which is connected. The receiving region is a region for generally receiving a part to be connected. The receiving region in particular comprises a recess having a section shape which corresponds at least substantially to the shape of the section of the part to be received in the receiving region. In a particularly preferred manner, the cavity is located in a plane which, starting from the center of the cavity, considered in the plane, extends over an angular range of at least 90 ° and preferably at least 180 ° and particularly preferably at least 270 ° relative to the walls of the coupling unit. The fact of corresponding substantially means in the present context that it is a approximation of at least 40%, preferably at least 60% and in a particularly preferential manner at most of 80% compared to the area of the section shape compared to the area of the section shape at least substantially corresponding by superposition. In addition, the expression "connected" means in particular that the reception regions are at least directly adjacent to an area. These include reception areas which in at least one adjacent area without leaving gaps. This produces a particularly advantageous and reliable coupling of the deflector unit with the wiper arm and the washing liquid channel. This allows in particular a very simple and intuitive assembly and a good use of the available space.
    According to another characteristic, the receiving region of the first coupling unit and the second coupling unit has a second common opening. The opening region is a region preferably an immaterial region which is adjacent to at least one receiving region and through which the adjacent receiving region can be connected directly to the environment of the deflector unit. Preferably, the region makes it possible to connect at least one adjacent reception region in a plane perpendicular to the main direction of extension of the reception region and / or of the deflector unit, directly with the environment of the deflector unit.
    Particularly preferably, the region is a region in which the adjacent reception region lies in a plane perpendicular to the main direction of extension of the reception region and / or of the deflector unit considered perpendicular to the main direction. extension of the receiving region and / or of the unit, of a material body of the first coupling unit and / or of the second coupling unit in an unlimited manner.
    The main direction of extension of a part and / or a region is the direction parallel to that of the largest side of the smallest parallelepiped enveloping the part and / or the region. This allows particularly simple mounting, in particular by coupling the coupling units in an opening region.
    According to another characteristic, the first coupling unit comprises a first reception region with an opening region and the second coupling unit comprises a second reception region with a second opening region different from the first opening region. This allows a particularly simple assembly, in particular it allows a separate coupling and decoupling of the units.
    According to another feature, the first opening region is on the side of the first receiving region opposite the second receiving region and the second opening region is on the side of the second receiving region at the opposite of the first receiving region. This allows an advantageously simple assembly and in particular it makes it possible to clearly separate the opening regions, which facilitates intuitive assembly.
    According to another advantageous characteristic, the deflector element has a cavity extending at least largely along the length of the deflector element in the main direction of extension. The fact is that it is the major part means in the present context that it represents at least 50%, preferably at least 70% and in a particularly preferential manner at least 90% of the whole . This makes it possible to produce an advantageously light deflector unit while being very stable.
    The deflector unit according to the invention which can advantageously be produced at least in part by an extrusion process, is not limited to the application and to the embodiment described above.

In the region of hinge 146 there is a spring element, not shown. This spring element presses the second wiper arm segment 144 against the second wiper arm segment 144 against the surface to be cleaned 140 in the region of application of the second arm segment 144. The surface to be cleaned 140 is a vehicle window. The first wiper arm segment 142 is connected to the motor vehicle in a non-detailed manner by an axis 148. The axis 148 considered in the main direction of extension 150 of the wiper arm 118 is connected to the rod 116 of the wiper arm 118 at its outer end. The axis 148 is driven by a motor, not shown. The end of the second wiper arm segment 144 opposite to that facing the hinge 146 carries a wiper arm adapter 152. The wiper arm adapter 152 is produced in one piece with the second wiper arm segment 144. The wiper arm adapter 152 receives the wiper blade adapter 154 carried by the wiper blade 138 The wiper arm adapter 152 receives the wiper blade adapter 154.
    The wiper blade 138 has an adapter 154. The wiper blade 138 is equipped with the adapter 154 to be coupled to the wiper arm 118. The wiper blade 138 also has a deflector unit 156, two elastic rails not shown, a wiping lip not shown and two end caps 158 of which only one is shown. The wiper blade 138 wipes in activity, the surface to be cleaned 140. The lip, not shown, of the wiper blade 138 presses against the surface to be cleaned 140 to wipe it. The lip, not shown, is held in the deflector unit 156 of the wiper arm by rails, not shown.
    The wiper arm device 136 has a washing liquid channel 122. This channel 122 conducts the washing liquid along the arm 118. The washing liquid channel 122 consists of a pipe. In addition, the washing liquid channel 122 has an essentially hollow cylindrical shape.

    Figure 2 shows the deflector unit 110a of the wiper arm device 136 with a deflector element 112a in the installed state. The wiper arm device 136 carries the deflector unit 110a. This deflector unit 110a has a main extension direction 166a which in the installed state corresponds to the main extension direction 150 of the wiper arm 118. The deflector unit 110a is constituted by a deflector unit wiper arms. The deflector unit 110a has a deflector element 112a which extends when looking in the main direction of extension 166a of the deflector unit 110a over the entire length of the deflector unit 110a. The deflector element 112a considered in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a has a generally triangular shape. The larger outer side of the deflector element 112a has a concave curvature in this plane. The second outer side of the deflector element 112a is bent in a concave shape in this plane. In addition, the deflector element 112a forms a cavity 168a. This cavity 168a of the deflector element 112a is considered along the main direction of extension 166a of the deflector unit 110a, over the entire length of the deflector element 112a. The cavity 168a has, in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a, an outer contour which corresponds substantially to the outer contour of the deflector element 112a on a reduced scale. The outer contour of the cavity 168a is analogous to the outer contours of the deflector element 112a in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a.
    The deflector unit 110a has a first coupling unit 114a. This first coupling unit 114a, in the installed state of the deflector unit 110a is connected to the rod 116 of the wiper arm 118. The first coupling unit 114a is connected to the second segment of the wiper arm -wiper 144 of the wiper rod 116. The first coupling unit 114a connects the deflector unit 110a to the rod 116 of the wiper arm 118. The first coupling unit 114a directly joins the element deflector 112a. The first coupling unit 114a, in the direction perpendicular to the main direction of extension 170 of the wiper rod 116 and perpendicular to the main direction of extension 166a, the deflector unit 110a to the element of deflector 112a. In addition, the first coupling unit 114a has a clip-on fastening element 124a. The clip-on fixing element 124a has two fixing branches 172a, 172a ’. The fixing branches 172a, 172a ’are formed in part by hooking elements. The fixing branches 172a, 172a ’have in a plane perpendicular to the main direction ίο of extension 166a of the deflector unit 110a, each in the form of an L-shaped section; the two fixing branches 172a, 172a ’are symmetrical, planar, one with respect to the other. The free ends of the L-shaped fixing branches 172a, 172a ’face each other. The sides of the fixing branches 172a, 172a 'are parallel. The two fixing branches 172a, 172a 'are connected to each other by their ends opposite those of the free ends on the second side, by a base side 174a of the clip-on fixing element 124a of the first coupling unit 114a. The base side 174a of the first coupling unit 114a is directly connected to the deflector element 112a.
    The first coupling unit 114a further comprises a reception region 128a. The receiving region 128a receives the rod 116 of the wiper arm 118. The receiving region 128a is used to receive the second segment 144 of the rod 116 of the wiper. The receiving region 128a has in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a, a shape which corresponds at least substantially to the shape of the section of the wiper blade rod 116 The reception region 128a extends in the main direction of extension 166a of the deflector unit 110a, over the entire length of this unit 110a of the reception region 128a extends parallel to the mainly extension direction 166a of the deflector unit 110a. The receiving region 128a considered in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a is delimited on four sides by the clip fixing fixing element 124a of the first coupling unit 114a. The receiving region 128a is bounded in one direction by the base side 174a of the snap fastener 124a. In the other three directions, the reception region 128a is delimited by the three fixing branches 172a, 172a ’; between the free ends of the two fixing elements 172a, 172a ’there is a gap 176a. In the interval 176a the rod 116 of the wiper arm 118 is put in the reception region 128a. Thus, by pushing the two fixing branches 172a, 172a ’, they are elastically deformed towards the outside to enlarge the interval 176a and allow passage 116 through the interval 176a.
    In addition, the deflector unit 110a includes a second coupling unit 120a; the second coupling unit 120a, in the installed state of the deflector unit 110a receives the washing liquid channel 122. The second coupling unit 120a receives a washing liquid channel 122 from the wiper arm device ice 136. The second coupling unit 120a connects the deflector unit 110a to the washing liquid channel 122. The second coupling unit 120a forms with the side opposite to that of the deflector element 112a, joining the first unit coupling 114a. The second coupling unit 120a comprises a clip-on fastening element 126a. This second coupling unit 120a, relative to the main extension plane 170 of the rod 116, on the side opposite to the deflector element 112a, the first coupling unit 114a. The clip-on fastener 126a consists of two fastening legs 178a, 178a '. The fixing branches 178a, 178a ’however are partly constituted by clipping elements. The fixing branches 178a, 178a 'are considered in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a, each a partial C-shaped opening and the two fixing branches 178a, 178a' are symmetrical one in relation to the other. The two fixing branches 178a, 178a 'of the second coupling unit 120a join the base side 174a of the first coupling unit 114a, at the opposite end to the two fixing branches 172a, 172a' of the first coupling unit 114a, directly to the fixing method 172, 172a 'of the first coupling unit 114a.
    The second coupling unit 120a further comprises a reception region 130a. The receiving region 130a is provided to receive the washing liquid channel 122. The receiving region 130a has in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a a section which corresponds substantially to the shape of the section of the washing liquid channel 122. The reception region 130a extends in the main direction of extension 166a of the deflector unit 110a over the entire length of this deflector unit 110a. The receiving region 130a extends parallel to the main direction of extension 166a of the deflector unit 110a. The receiving region 130a is, considered in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a, largely delimited by the fixing spacers 178a, 178a 'of the second coupling unit 120a and by the fixing spacers 172a, 172a 'of the first coupling unit 114a. The gap 176a between the fixing spacers 172a, 172a ’of the first coupling unit 114a directly join the reception region 130a. On one side of the receiving region 130a not facing the gap 176a of the first coupling unit 114a there is a gap 180a between the two fixing spacers 178a, 178a ’of the second coupling unit 120a. The interval 180a of the second coupling unit 120a allows the rod 116 of the wiper arm 118 to be placed on the one hand in the receiving region 130a of the second coupling unit 120a and by the interval 176a of the first unit coupling 114a in the receiving region 128a of the first coupling unit 114a. In addition, the interval 180a of the second coupling unit 120a makes it possible to place the washing liquid channel 122 in the reception region 130a of the second coupling unit 114a.
    By pushing the two fixing branches 178a, 178a ’, they can be elastically deformed by moving them apart to enlarge the interval 180a and allow the rod 116 or the washing liquid channel 122 to pass through the interval 180a.
    The first coupling unit 114a and the second coupling unit 120a each have a snap fastener 124a, 126a. The snap fasteners 124a, 126a are in one piece. In addition, the first coupling unit 114a and the second coupling unit 120a each have a receiving region 128a, 130a. The receiving regions 128a, 130a of the first coupling unit 114a and the second coupling unit 120a are respectively connected to each other. The receiving regions 128a, 130a of the first coupling unit 114a and of the second coupling unit 120a are connected directly to each other by the interval 176a of the first coupling unit 114a. The receiving regions 128a, 130a of the first coupling unit 114a and the second coupling unit 120a further have a common opening region 132a. The two reception regions 128a, 130a considered in a plane perpendicular to the main direction of extension 166a of the deflector unit 110a are connected to the outside by the interval 180a of the second coupling unit 120a and thus have a common opening region 132a.
    In addition, the deflector element 112a is made in one piece with the first coupling unit 114a and with the second coupling unit 120a. The deflector element 112a, the first coupling unit 114a and the second coupling unit 120a are made in one piece. The deflector element 112a, the first coupling unit 114a and the second coupling unit 120a are made of the same material. The entire deflector unit 110a is manufactured by extrusion.
    In addition, the deflector unit 110a preferably has a locking element, not shown. The locking element blocks the deflector unit 110a on the rod 116 of the wiper arm 118. The locking element prevents any accidental loosening of the rod 116 of the wiper arm 118 which could come out of the first coupling unit 114a. In addition, the locking member fixes the washing liquid channel 122 to the deflector unit 110a. The locking element prevents accidental detachment of the washing liquid channel 122 from the second coupling unit 120a. We can envisage different technically interesting realizations for the locking element.
