Description

Wiper motor holding device

Background

A wiper motor holding device for fixing a wiper motor to a carrier part has already been proposed, which has a base body and at least one pre-fixing unit that can be arranged on the base body and serves to pre-position the base body relative to the wiper motor.

Disclosure of Invention

The invention relates to a wiper motor retaining device for fixing a wiper motor to a carrier part, comprising a base body and at least one pre-fixing unit that can be arranged on the base body and is used for pre-positioning the base body relative to the wiper motor.

It is proposed that the pre-fixing unit has at least one lateral projecting part which, at least in the mounted state, is provided for limiting the movement of the base body relative to the wiper motor to at least one degree of freedom. Preferably, the transverse projecting part is provided in the mounted state for limiting the movement of the base body relative to the wiper motor in at least one direction in at least one degree of freedom. "wiper motor retaining device" is understood to mean, in particular, a device which is provided for fastening a wiper motor to a carrier part, in particular a carrier tube. This preferably means in particular a device which is provided for the secure fixing of the carrier part in the receptacle of the wiper motor. The device is preferably provided for clamping the carrier part in a receptacle of the wiper motor. This particularly preferably means a plate motor holder. In principle, however, alternative designs of the wiper motor holding device which appear to be expedient to the person skilled in the art are also conceivable. Furthermore, the term "carrier part" is understood to mean, in particular, a part which is provided for positioning and/or fixing the wiper motor in the motor vehicle. This preferably means in particular a component which is provided for rigidly coupling the housing of the wiper motor to at least a part of the wiper rod. This particularly preferably means a carrier tube. Furthermore, a "pre-fixing unit" is in particular relevant to a unit which is provided for pre-positioning the base body relative to the wiper motor. This preferably means, in particular, a unit which is provided for the purpose of pre-positioning and/or fixing the base body relative to the wiper motor in the mounted state of the wiper motor retaining device. This particularly preferably means, in particular, a unit which is provided for the preliminary positioning and/or fixing of the base body relative to the wiper motor for mounting on the wiper motor, in order in particular to achieve a reliable and rapid final fixing. "pre-positioning" means in particular that positioning is only achieved at least substantially by the pre-fixing unit for a limited period of time, in particular during installation. Furthermore, a "transversely protruding component" is understood to mean, in particular, a component of the pre-fixing unit which extends at least approximately transversely to the main extension plane of the wiper motor holding device. This preferably means a component which projects from the base body transversely to the main extension plane of the base body, in particular projects relative to the base body. This is particularly a component which is provided for a direct positioning of the base body in at least one direction relative to the wiper motor. In this context, a "main extension plane" of a structural unit and/or body means in particular a plane which runs parallel to the largest side of the smallest geometric cube which can just yet completely enclose the structural unit and/or body, and in particular runs through the center of this cube. Furthermore, "installed state" is, in particular, a state in which: in this state, the wiper motor is fixed to the carrier member by means of the wiper motor holding device. "limiting the movement to at least one degree of freedom" means in particular that the laterally projecting part is provided for limiting a possible movement of the base body relative to the wiper motor to at least one degree of freedom. This preferably means, in particular, that the laterally projecting part is provided for at least partially limiting a possible movement of the base body relative to the wiper motor in at least one direction and/or in at least one plane of rotation. In this context, "degree of freedom" means in particular the possibility of movement of a structural unit and/or a body in an independent direction or in an independent plane of rotation. A rigid structural unit and/or a rigid body therefore has six degrees of freedom in space, wherein three degrees of freedom are always formed by mutually independent directions, in particular perpendicular to one another, and three degrees of freedom are always formed by mutually independent planes of rotation. "provided" means especially specially designed and/or configured. By "an object is provided for a certain function" is meant in particular that the object realizes and/or carries out said certain function in at least one application state and/or operating state.

With the wiper motor holding device according to the invention, in particular, an advantageously simple mounting of the wiper motor on the carrier part can be achieved. In particular, a quick and simple final installation can be achieved by the preliminary positioning. This preferably makes it possible to avoid skewing of the screws during installation and/or other disturbances. In addition, the installation space of the wiper motor holding device can be kept small in particular by the lateral extension of the lateral projecting element.

It is furthermore proposed that at least one transverse projection of the pre-fixing unit projects from the base body at least approximately perpendicularly to the main extension plane towards the wiper motor. Preferably, at least one transverse projection of the pre-fixing unit projects from the base body at least approximately perpendicularly to the main extension plane of the wiper motor holding device towards the wiper motor. "at least approximately perpendicular" means in particular that the smallest angle between the main extension plane and the transverse projection extension is at least 65 °, preferably at least 75 °, particularly preferably at least 85 °. This advantageously ensures particularly reliable positioning. Furthermore, the vertical extension of the transverse projecting element makes it possible in particular to keep the installation space of the wiper motor retaining device small. In particular, the installation space in the direction of the main extension plane can be kept small. This makes it possible in particular to achieve an advantageously compact overall size.

It is also proposed that at least one transverse projecting part of the pre-fixing unit is constructed integrally with the base body. "integrally" means in particular at least a material-to-material connection, for example a connection by means of a welding process, an adhesive process, an injection-molding process and/or another process which appears to be expedient to the person skilled in the art, and/or advantageously integrated, for example by being produced from a casting compound and/or by using a single-component or multi-component injection molding method and advantageously being produced from a separate blank and/or by being produced from a separate sheet material. The number of components can thereby advantageously be kept small. This also advantageously enables a simple and quick assembly of the wiper motor retaining device. In addition, a high stability of the wiper motor holding device can be achieved in particular.

It is also proposed that at least one of the laterally projecting parts of the pre-fixing unit has at least one contact region which, in the mounted state, contacts at least one holding part of the carrier part receptacle of the wiper motor. The term "contact region" is understood to mean in particular a partial region of the transversely projecting part which is provided for contacting the wiper motor, in particular the holding part of the wiper motor. This preferably means, in particular, a contact region of the laterally projecting element with which the laterally projecting element contacts the wiper motor at least in the mounted state. Furthermore, "holding element" is in particular a component which limits the carrier element receptacle in at least one direction. This preferably means, in particular, a component of the wiper motor which is provided to hold the received carrier part at least partially in the carrier part reception. The component is preferably also provided for connection to a wiper motor retaining device in the mounted state. Particularly preferably, the wiper motor holding device is connected to the wiper motor in the mounted state via a holding part. Furthermore, the term "carrier element receptacle" is used in a related manner, in particular, to mean a recess in the wiper motor which is provided to receive the carrier element at least in the installed state. This makes it possible to achieve an advantageously reliable positioning.

It is also proposed that at least one of the laterally projecting parts of the pre-fixing unit is configured as a tongue. The laterally projecting part configured as a tongue is preferably bent from a part of the base body. This makes it possible to achieve a particularly advantageously reliable positioning. Furthermore, by configuring the tongue, an advantageously compact transverse projecting element can be provided in particular. This also makes it possible to achieve an advantageously compact size of the wiper motor holding device.

It is also proposed that the contact area of at least one of the transverse projections is offset with respect to the base body. "offset" means in particular that the contact region of at least one transversely projecting part is connected to the main part only indirectly via a further partial region. This preferably means, in particular, that the contact area is formed at a distance from the base body, wherein a gap is formed between the base body and the contact area. In this way, radii in the connecting region between the contact region and the main body can be avoided particularly advantageously. In particular, a high positioning accuracy of the contact area can be achieved in this way.

It is also proposed that at least one transverse projection of the pre-fixing unit is designed as a deep-drawn region of the base body. "deep-drawn region" in this connection means in particular a region which is preferably formed by a deep-drawing process. This preferably means in particular the following regions: viewed perpendicularly to the main extension plane of the base body, the base of the region is arranged offset with respect to the base surface of the base body. This preferably means, in particular, a region which is recessed with respect to a main surface of the base body. An advantageous transverse projection can thereby be provided. In particular, a transverse projection which can be produced advantageously easily can be provided thereby. Furthermore, an advantageous positioning can be achieved thereby.

It is also proposed that the pre-fixing unit has at least one further transverse projecting part which, at least in the mounted state, is provided for limiting the movement of the base body relative to the wiper motor to at least one degree of freedom. The further laterally projecting part is preferably at least approximately identically configured compared to the laterally projecting part. In particular, this makes it possible to mount the wiper motor advantageously simply on the carrier part. Particularly reliable positioning can also be advantageously achieved.

It is also proposed that the at least one transverse projection and the at least one further transverse projection of the pre-fixing unit are at least approximately mirror-symmetrically configured to each other. In particular, a particularly reliable and precise positioning can be achieved by means of a mirror-symmetrical arrangement.

It is also conceivable for the pre-fixing unit to have at least one pre-fixing recess which, in the installed state, is provided for receiving a fixing pin of the workpiece carrier. The at least one pre-fixing indentation of the pre-fixing unit is preferably arranged at least partially between the at least one fixing part and the adjusting part. In particular, a secure fastening can thereby be provided, whereby in particular an advantageously simple and secure installation can be achieved. Furthermore, the pre-fixing indentation can be arranged in particular in an area which is present anyway. This also makes it possible to keep the material requirements small and to achieve a compact design.

A system with a wiper motor, a carrier part and a wiper motor retaining device is also proposed.

The wiper motor holding device according to the invention and/or the system according to the invention should not be limited to the above-described applications and embodiments. The wiper motor holding device according to the invention and/or the system according to the invention can have a number of individual components, components and units which differs from the number described here, in particular for realizing the operating modes described here. Further, with respect to the value ranges disclosed herein, values that are within the stated limits should also be considered disclosed, and may be arbitrarily employed.

Detailed Description

Fig. 1 shows a system 32a with a wiper motor 12, a carrier part 14 and a wiper motor holding device 10 a. The wiper motor 12 includes an electric motor 34 and a gear train 36 operatively connected to the electric motor 34. The gear mechanism 36 has a gear mechanism housing 38, which is firmly connected to a motor housing 40 of the electric motor 34. The carrier part 14 is configured as a carrier tube. The carrier part 14 is also provided for positioning and fixing the wiper motor 12 in the vehicle, which cannot be seen further. By means of the carrier part 14, the gear housing 38 of the wiper motor 12 is rigidly coupled with a part of the wiper rod that cannot be seen further, which is driven by the wiper motor 12.

The wiper motor 12 has a bearing member accommodating portion 28. The gear housing 38 has a carrier receptacle 28. The carrier receiving portion 28 forms a U-shaped recess into which the carrier 14 can be inserted. The U-shaped recess is open on three sides. The U-shaped recess opens toward the top side of the gear housing 38 and opens toward opposite sides. The U-shaped recess also extends parallel to the axis of the motor 34. The U-shaped recess is delimited in three directions by the material of the carrier receiving part 28. The U-shaped recess is delimited in one direction by the two retaining

parts

26, 42. The retaining

members

26, 42 form part of the transmission housing 38. The holding

parts

26, 42 are each designed as a dome. The holding

parts

26, 42 are arranged spaced apart from one another and are connected to one another by a wall 44. The holding

parts

26, 42 are arranged on the outer edge of the gear housing 38 on the side facing away from the motor axis. The holding

parts

26, 42 project from the basic shape of the gear housing 38 toward the top side of the gear housing 38. Furthermore, a driven shaft 46 of the wiper motor 12 projects from the top side of the gear housing 38. The driven shaft 46 drives a crank 48, which has a ball joint at its end. The crank 48 is firmly connected to the driven shaft 46.

The wiper motor retaining device 10a is provided for fixing the wiper motor 12 on the carrier member 14. The wiper motor retaining device 10a is provided for the purpose of fixing the carrier part 14 in a carrier part receptacle 28 of the wiper motor 12 in a secure manner. The wiper motor holding device 10a is provided for clamping the carrier part 14 in the carrier part receptacle 28 of the wiper motor 12. The wiper motor holding device 10a is configured as a plate-type motor holder. In principle, however, another design of the wiper motor retaining device 10a is also conceivable, which would be considered appropriate by the person skilled in the art.

The wiper motor retaining device 10a has a base body 16 a. The base body 16a is formed of a rectangular plate material. The base body 16a has two

recesses

52a, 54a extending along the main direction of extension 50a of the base body 16 a. Viewed in the main direction of extension 50a of the base body 16a, these

depressions

52a, 54a each extend over the entire length of the base body 16 a. The

depressions

52a, 54a are arranged on opposite sides of the base body 16a, viewed perpendicularly to the main direction of extension 50a of the base body 16a and parallel to its main extension face 56 a. In addition,

depressions

52a, 54a are formed by a deep drawing process.

Recesses

52a, 54a are provided for the rigidity of base 16 a. In principle, however, other means for increasing the rigidity that would be useful to the person skilled in the art are also conceivable. The base 16a also has a central elongated recess 58 a. The recess 58a is disposed between the two

recesses

52a, 54 a. The recess 58a extends substantially parallel to the main direction of extension 50a of the base body 16 a. In the mounted state of the wiper motor holding device 10a, the output shaft 46 of the wiper motor 12 acts on the wiper motor 12 via the recess 58 a. The recess 58a is dimensioned such that the output shaft 46 can pass through the recess 58a when the crank 48 is mounted thereon. In principle, however, alternative designs of the size of the recess 58a which would be obvious to a person skilled in the art are also conceivable.

The wiper motor retaining device 10a also has a pre-fixing unit 18a that can be arranged on the base body 16 a. The pre-fixing unit 18a is provided for pre-positioning the base body 16a relative to the wiper motor 12. The pre-fixing unit 18a is formed integrally with the base body 16 a. The pre-fixing unit 18a has a laterally projecting part 20 a. The lateral projecting member 20a is provided for restricting the movement of the base 16a relative to the wiper motor 12 to one degree of freedom in the mounted state. By the laterally protruding member 20a, the movement of the base 16a relative to the wiper motor 12 is restricted in one direction in the mounted state. The laterally projecting part 20a of the previously fixed unit 18a projects from the base body 16a toward the wiper motor 12 perpendicularly to the main extension surface 22a of the wiper motor holding device 10 a. The main extension surface 22a of the wiper motor retaining device 10a extends parallel to the main extension surface 56a of the base body 16 a. The transverse projecting part 20a of the pre-fixing unit 18a is constructed integrally with the base body 16 a. The laterally projecting part 20a of the pre-fixing unit 18a is bent from a portion of the base 16 a. A laterally projecting element 20a is provided at one end of the recess 52a, viewed along the main extension 56a of the base 16 a. Laterally projecting members 20a are provided on the inner side of the recess 52a, i.e. on the side facing the opposite recess 54 a. Furthermore, the transverse projecting part 20a is designed as a tongue. In principle, however, alternative designs of the transverse projection 20a which appear to be expedient to the person skilled in the art are also conceivable. The main extension plane of the laterally projecting element 20a encloses a minimum angle of approximately 45 ° with the main extension direction 50a of the basic body 16 a. In principle, however, other angles which would be obvious to the person skilled in the art are also conceivable. Furthermore, the main extension plane of the transverse projecting element 20a extends perpendicularly to the main extension plane 56a of the base body 16a (fig. 2).

The laterally projecting part 20a of the pre-fixing unit 18a has an abutment region 24 a. The contact region 24a contacts the holding part 26 of the carrier receptacle 28 of the wiper motor 12 in the mounted state. The contact surface 24a extends parallel to the main extension of the transverse projection 20 a. The contact area 24a is formed by the side of the transversely projecting part 20a facing the recess 52. The contact region 24a contacts the holding part 26 of the wiper motor 12 at the upper end of the holding part 26 in the mounted state (fig. 2).

The pre-fixing unit 18a also has another transverse projecting part 30 a. The further lateral projecting part 30a is also provided for limiting the movement of the base body 16a relative to the wiper motor 12 to one degree of freedom in the mounted state. By the other lateral projecting member 30a, the movement of the base body 16a relative to the wiper motor 12 is restricted in the other direction in the mounted state. The transverse projecting part 20a and the further transverse projecting part 30a of the pre-fixing unit 18a are configured mirror-symmetrically to each other. The transverse projection 20a and the further transverse projection 30a are mirror-symmetrically configured with respect to a mirror plane 60a, which extends perpendicularly to the main extension plane 56a of the main body 16a and parallel to the main extension direction 50a thereof through a geometric midpoint of the main body 16 a. The other laterally projecting part 30a of the previously fixed unit 18a also projects from the base body 16a toward the wiper motor 12 perpendicularly to the main extension surface 22a of the wiper motor holding device 10 a. Furthermore, a further transverse projection 30a is also constructed integrally with the base body 16 a. The other laterally projecting part 30a is bent from a portion of the base 16 a. Viewed in the main direction of extension 50a of the base body 16a, a further transversely protruding part 30a is arranged at one end of the recess 54 a. Furthermore, a further laterally projecting part 30a is arranged on the inner side of the depression 54a, i.e. on the side facing the opposite depression 52 a. The other laterally projecting part 30a is also designed as a tongue. The main extension plane of the further laterally projecting element 30a encloses a minimum angle of approximately 45 ° with the main extension direction 50a of the basic body 16 a. Furthermore, the main extension plane of the further transverse projection 30a extends perpendicularly to the main extension plane 56a of the base body 16a (fig. 2).

In addition, the other transversely projecting part 30a of the pre-fixing unit 18a also has an abutment region 62 a. In the mounted state, this contact region 62a contacts the holding part 42 of the carrier part receptacle 28 of the wiper motor 12. The contact region 62a contacts the holding part 42 of the wiper motor 12 at the upper end of the holding part 42 in the mounted state. The contact areas 24a, 62a of the transversely projecting elements 20a, 30a thus contact the holding

elements

26, 42 on the sides of the holding

elements

26, 42 that face each other approximately. In this way, particularly reliable positioning can be achieved (fig. 2).

In addition, the wiper motor holding device 10a has a fixing unit 64 a. The fixing unit 64a is provided for firmly connecting the wiper motor holding device 10a with the wiper motor 12. The fixing unit 64a has four

screws

66a, 66a ', 68 a'. In the mounted state, these

screws

66a, 66a ', 68a' are each screwed into the wiper motor 12 through a recess in the base body 16a that is not visible further. In the mounted state, the

screws

66a, 66a ', 68a' are screwed into the gear housing 38. The first screw 66a is screwed into the holding member 26 of the wiper motor 12 through a recess. The recess is formed in a recess 52a of the base body 16a at the end facing the transversely protruding part 20 a. The second screw 66a' is screwed into the holding member 42 of the wiper motor 12 through a recess. The recess is formed in a recess 54a of the base body 16a at the end facing the other laterally projecting part 30 a. A third screw 68a is screwed into the gear mechanism housing 38 through a recess on the side of the carrier receptacle 28 opposite the holding part 26. The recess is formed next to the recess 58a in the recess 52a of the base body 16 a. A fourth screw 68a' is screwed into the gear mechanism housing 38 through a recess on the side of the carrier receptacle 28 opposite the holding part 42. The recess is formed next to the recess 58a in the recess 54a of the base body 16a (fig. 2).

In addition, the wiper motor holding device 10a has a pressing unit 70 a. The pressing unit 70a is provided in the mounted state of the wiper motor holding device 10a to press the carrier member 14 into the carrier member receptacle 28 and thus to fix the carrier member 14 to the wiper motor 12. The hold-down unit 70a has two hold-down

elements

72a, 72a', which, in the mounted state of the wiper motor retaining device 10a, project into a U-shaped recess formed by the carrier receptacle 28. The

pressing elements

72a, 72a' are formed by deep-drawn regions of the base body 16 a. First pressing element 72a is disposed in recess 52a of base 16a between the recess of first screw 66a and the recess of third screw 68 a. First pressing member 72a is deep-drawn into recess 52a of base 16 a. A second pressing part 72a ' is arranged in the recess 54a of the base body 16a between the recess of the second screw 66a ' and the recess of the fourth screw 68a '. The second pressing part 72a' is deep-drawn into the recess 54a of the base body 16 a. In principle, however, it is also conceivable for the carrier part 14 to be pressed into the carrier part receptacle 28 solely via the base body 16a without a pressing part, in order to fix the carrier part 14 to the wiper motor 12. This can be taken into account in particular when the diameter of the carrier part 14 is sufficiently large.

In addition, the wiper motor holding device 10a has an adjusting member 74 a. The wiper motor 12 in the motor vehicle can be adjusted by means of the adjusting element 74 a. The wiper motor 12 is prevented from moving or rotating on the carrier member 14 by the adjustment member 74 a. The adjustment member 74a may be formed by a ring with a central recess. The adjusting member 74a is constituted by a rubber ring. Viewed in the main direction of extension 50a of the base body 16a, the adjusting element 74a is arranged at the end of the base body 16a facing away from the laterally projecting elements 20a, 30 a. The adjustment member 74a is disposed between the

depressions

52a, 54a of the base 16 a.

Further, the pre-fixing unit 18a has a pre-fixing recess 76 a. The pre-fixing recess 76a is provided in the mounted state for restricting the movement of the base body 16a relative to the wiper motor 12 to two degrees of freedom. Furthermore, the preliminary fixing recess 76a is provided in the mounted state with a fixing pin 78 for receiving the workpiece carrier. Only the retaining pin 78 of the workpiece support is visible in fig. 1. In order to position the wiper motor holding device 10a relative to the wiper motor 12, a fixing pin 78 is inserted into the preliminary fixing recess 76 a. The pre-fixing recess 76a is formed by a through hole opened in the base body 16 a. The preliminary fixing concavity 76a of the preliminary fixing unit 18a is provided between the fixing unit 64a and the regulating member 74 a. A pre-fixing indent 76a is provided between the adjustment member 74a and the indent 58 a. The pre-fixing indentation 76a opens out in the base body 16a between the

indentations

52a, 54a of the base body 16 a. The pre-fixing indentation 76a is thus formed in the base body 16a in the area of the base body 16a which is present in itself. The base 16a need not be enlarged.

In the installed state, the wiper motor 12 is arranged stationary on the workpiece carrier. The wiper motor holding device 10a with the pre-fixing recess 76a can be positioned relative to the workpiece carrier and thus also relative to the wiper motor 12 by means of the fixing pin 78. Here, the fastening pin 78 passes directly next to the wiper motor 12 and protrudes into the pre-fastening recess 76a of the wiper motor retaining device 10 a. In this state, however, the wiper motor retaining device 10a can still rotate relative to the workpiece support and the wiper motor 12. To achieve the final positioning for mounting, the wiper motor holding device 10a is suitably rotated so that the laterally projecting parts 20a, 30a abut against the holding

parts

26, 42 of the carrier part receptacle 28 of the wiper motor 12, thereby preventing rotation. The

screws

66a, 66a ', 68a' can then be screwed into place. This reliably prevents the

screws

66a, 66a ', 68a' from skewing during installation and enables quick screwing. High process reliability and high efficiency can be achieved at the time of installation.

Three other embodiments of the present invention are shown in FIGS. 3-6. The following description is essentially limited to the differences between the exemplary embodiments, wherein, with regard to the same components, features and functions, reference is made to the description of the further exemplary embodiments, in particular to the description of fig. 1 and 2. In order to distinguish the wiper motor holding device of these embodiments, the letter a in the reference numeral of the wiper motor holding device of the embodiment in fig. 1 and 2 is replaced with the letters b, c, and d in the reference numeral of the wiper motor holding device of the embodiment in fig. 3 to 6.

Fig. 3 shows a partial sectional view of the wiper motor holding device 10b with the pre-fixing unit 18 b. The pre-fixing unit 18b is provided for pre-positioning the base body 16b of the wiper motor holding device 10b relative to the wiper motor 12. The pre-fixing unit 18b has a laterally projecting part 20 b. The laterally projecting part 20b of the previously fixed unit 18b projects from the base body 16b toward the wiper motor 12 perpendicularly to the main extension plane of the wiper motor holding device 10 b. The laterally projecting part 20b of the pre-fixing unit 18b is bent from a portion of the base 16 b. Viewed in the main direction of extension 50b of the base body 16b, a transversely protruding part 20b is arranged at one end of a recess 52b of the base body 16 b. The laterally projecting part 20b is arranged on the inner side of the depression 52b, i.e. on the side facing the opposite depression 54b of the base body 16 b. Furthermore, the transverse projecting part 20b is designed as a tongue. The main extension plane of the laterally protruding part 20b extends parallel to the main extension direction 50b of the base body 16 b. Furthermore, the main extension plane of the lateral protruding part 20b extends perpendicular to the main extension plane of the base body 16 b. By providing the lateral projecting part 20b, particularly high positioning and fixing efficiency can be achieved, since the rotation angle in case of error can be significantly limited.

The laterally projecting part 20b of the pre-fixing unit 18b has an abutment region 24 b. The contact region 24b contacts the holding part 26 of the carrier receiving part 28 of the wiper motor 12 in the mounted state. The contact surface 24b extends parallel to the main extension of the transverse projection 20 b.

The pre-fixing unit 18b also has another laterally projecting part 30 b. The transverse projecting part 20b and the further transverse projecting part 30b of the pre-fixing unit 18b are configured mirror-symmetrically to each other. The transverse projection 20b and the further transverse projection 30b are mirror-symmetrically configured with respect to a mirror plane 60b, which extends perpendicular to the main extension plane of the main body 16b and parallel to the main extension direction 50b thereof through a geometric midpoint of the main body 16 b. Viewed in the main direction of extension 50b of the base body 16b, a further transversely protruding part 30b is arranged at one end of the recess 54 b. Furthermore, a further laterally projecting part 30b is arranged on the inner side of the depression 54b, i.e. on the side facing the opposite depression 52 b. The other laterally projecting part 30b is also designed as a tongue. The main extension plane of the further transverse projection 30b extends parallel to the main extension direction 50b of the base body 16 b. Furthermore, the main extension plane of the further transverse projecting element 30b extends perpendicularly to the main extension plane of the base body 16 b.

In addition, the other transversely projecting part 30b of the pre-fixing unit 18b also has an abutment region 62 b. In the mounted state, this contact region 62b contacts the holding part 42 of the carrier part receptacle 28 of the wiper motor 12. The contact region 62b contacts the holding part 42 of the wiper motor 12 at the upper end of the holding part 42 in the mounted state. The

contact areas

24b, 62b of the transverse projecting

elements

20b, 30b thus contact the holding

elements

26, 42 on the sides of the holding

elements

26, 42 facing each other.

In addition, the wiper motor holding device 10b has a fixing unit. The fixing unit is provided for firmly connecting the wiper motor holding device with the wiper motor 12. The fixing unit has four screws. In the mounted state, these screws are screwed into the wiper motor 12 through

respective recesses

80b, 80b ', 82b' in the base body 16 b. In the mounted state, the screw is screwed into the gear housing 38. A first recess 80b is formed in the recess 52b of the base 16b at the end facing the laterally projecting part 20 b. A second recess 80b' is formed in the recess 54b of the base 16b at the end facing the other laterally protruding part 30 b. Third recess 82b is formed in recess 52b of base 16b adjacent recess 58b of base 16 b. A fourth recess 82b' is formed in recess 54b of base 16b adjacent recess 58 b.

Fig. 4 shows a partial sectional view of the wiper motor holding device 10c with the pre-fixing unit 18 c. The preliminary fixing unit 18c is provided for preliminarily positioning the base body 16c of the wiper motor holding device 10c with respect to the wiper motor 12. The pre-fixing unit 18c has a laterally projecting part 20 c. The laterally projecting part 20c of the previously fixed unit 18c projects from the base body 16c toward the wiper motor 12 perpendicularly to the main extension plane of the wiper motor holding device 10 c. The lateral projecting part 20c of the pre-fixing unit 18c is formed by bending a part of the base 16 c. Viewed in the main direction of extension 50c of the base body 16c, a laterally protruding part 20c is arranged at one end of a recess 52c of the base body 16 c. The laterally projecting part 20c is arranged on the base body 16c at the end side of the recess 52 c. Furthermore, the transverse projecting part 20c is designed as a tongue. The laterally projecting element 20c has an abutment region 24c and a connecting region 84 c. The contact areas 24c of the transverse projections 20c are offset with respect to the base body 16 c. The contact region 24c is therefore not directly connected to the main body 16 c. The contact region 24c is connected to the base body 16c via a connecting region 84 c. In the mounted state, the contact region 24c contacts the holding part 26 of the carrier part receptacle 28 of the wiper motor 12. The contact region 24c is bent with respect to the connecting region 84 c. The main extension plane of the connecting region 84c of the laterally projecting element 20c extends perpendicularly to the main extension direction 50c of the basic body 16 c. The main extension plane of the contact region 24c encloses a minimum angle of approximately 45 ° with the main extension direction 50c of the main body 16 c. In principle, however, other angles which would be obvious to the person skilled in the art are also conceivable. Furthermore, the main extension of the contact region 24c extends perpendicularly to the main extension of the main body 16 c.

The pre-fixing unit 18c also has another laterally projecting part 30 c. By the other lateral projecting member 30c, the movement of the base body 16c relative to the wiper motor 12 is restricted in the other direction in the mounted state.

The transverse projection 20c and the further transverse projection 30c are mirror-symmetrically configured with respect to a mirror plane 60c, which extends perpendicular to the main extension plane of the main body 16c and parallel to the main extension direction 50c thereof through a geometric midpoint of the main body 16 c. Viewed in the main direction of extension 50c of the base body 16c, a further transversely protruding part 30c is arranged at one end of the recess 54c of the base body 16 c. Another lateral projecting part 30c is provided on the base body 16c at the end side of the undercut 54 c. Furthermore, the further transverse projecting part 30c is designed as a tongue. The other laterally projecting element 30c has an abutment region 62c and a connecting region 86 c. The contact region 62c of the other transverse projection 30c is offset with respect to the base body 16 c. The contact region 62c is therefore not directly connected to the main body 16 c. The contact region 62c is connected to the base body 16c via a connecting region 86 c. In the mounted state, the contact region 62c contacts the holding part 26 of the carrier part receptacle 28 of the wiper motor 12. The abutment region 62c is bent with respect to the connection region 86 c. The main extension plane of the connecting region 86c of the further transverse projection 30c extends perpendicularly to the main extension direction 50c of the base body 16 c. The main extension plane of the contact region 62c encloses a minimum angle of approximately 45 ° with the main extension direction 50c of the main body 16 c. Furthermore, the main extension of the contact region 62c extends perpendicularly to the main extension of the main body 16 c.
