The wiper motor has a pole pot and the end of the pot has a mounting point for mounting the motor on a body. OBJECT OF THE INVENTION The object of the present invention is to develop an improved wiper drive apparatus. DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the invention relates to a windscreen wiper drive device for a windscreen wiper system, in particular a windscreen wiper system of a motor vehicle equipped with an engine. electric motor provided with a pole pot connected to a transmission housing, comprising at least one motor fixing point in a variable position for attachment to a support, in particular a vehicle body.

Le dispositif d'entraînement d'essuie-glace selon l'inven- tion a l'avantage d'une plus grande souplesse de montage. Suivant une caractéristique, le point de fixation souple est réalisé par un collier muni d'une broche. Le collier est fixé au pot polaire. Grâce à la réalisation comme collier (collier pour tuyau), la broche qui constitue le point de fixation peut être glissée suivant l'axe The windscreen wiper drive according to the invention has the advantage of greater mounting flexibility. According to one characteristic, the flexible attachment point is made by a collar provided with a pin. The collar is attached to the polar pot. Thanks to the realization as collar (collar for hose), the pin which constitutes the point of fixation can be slid along the axis

2 longitudinal du pot polaire et aussi tourner autour de son axe de rotation. Cela permet d'aligner la position de la broche de manière souple en fonction du point de raccordement à la carrosserie. Dessin La présente invention sera décrite ci-après de manière plus détaillée à l'aide d'un exemple de réalisation représenté schématiquement dans l'unique figure annexée qui est une vue de côté du dispositif d'entraînement selon l'invention. Description d'un mode de réalisation préférentiel de l'invention La figure montre schématiquement un dispositif d'entraînement d'essuie-glace 1 pour un système d'essuie-glace d'une installation d'essuie-glace d'un véhicule automobile. Le dispositif d'entraînement d'essuie-glace 1 comporte un boîtier de transmission 2 relié au pot polaire 3 d'un moteur électrique 11. Le boîtier de transmis- Sion 2 comporte une première broche 4 et une seconde broche 6 constituant des points de fixation. Les points de fixation servent à fixer le dispositif d'entraînement d'essuie-glace 1 à un support, notamment à une carrosserie de véhicule. Pour cela, le support comporte des orifices dans lesquels peuvent s'engager les broches 4, 6. Un arbre de sortie 5 dépasse du boîtier de transmission 2 pour entraîner l'arbre de l'essuie-glace. En fonction du mode de réalisation choisi, les broches peuvent être prévues directement sur le boîtier de transmission ou sur une platine du moteur. En règle générale, on utilise trois points de fixation, c'est- à-dire trois broches pour fixer le moteur à la carrosserie d'un véhicule. Dans un mode de réalisation simple, on peut également n'utiliser que deux points de fixation pour fixer le moteur à la carrosserie. Le pot polaire 3 a une forme essentiellement cylindrique et il est aligné suivant un axe longitudinal 7. Un troisième point de fixa- tion 9 équipe le pot polaire 3 ; ce point de fixation est relié au pot polaire 3 par un moyen de fixation 8. Les moyens de fixation 8 sont réalisés pour permettre de modifier simplement la position du troisième point de fixation et, à cet effet, ils ont la forme d'une broche 9. Dans le mode de réalisation représenté, le moyen de fixation est constitué par un collier 8 (collier pour tuyau) serré solidement au pot polaire. Le col- 2 longitudinal pole and also rotate around its axis of rotation. This makes it possible to align the position of the spindle flexibly according to the point of connection to the bodywork. The present invention will be described in more detail below with reference to an exemplary embodiment shown schematically in the single accompanying figure which is a side view of the drive device according to the invention. DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION The figure shows schematically a windscreen wiper drive device 1 for a wiper system of a windscreen wiper system of a motor vehicle. The wiper drive device 1 comprises a transmission housing 2 connected to the pole pot 3 of an electric motor 11. The transmission housing Sion 2 comprises a first pin 4 and a second pin 6 constituting grounding points. fixation. The attachment points serve to secure the wiper drive device 1 to a support, in particular to a vehicle body. For this, the support has orifices in which the pins 4, 6 can engage. An output shaft 5 protrudes from the transmission housing 2 to drive the wiper shaft. Depending on the embodiment chosen, the pins may be provided directly on the transmission housing or on an engine plate. As a general rule, three attachment points are used, ie three pins to fix the motor to the bodywork of a vehicle. In a simple embodiment, it is also possible to use only two fixing points to fix the motor to the bodywork. The pole pot 3 has a substantially cylindrical shape and is aligned along a longitudinal axis 7. A third attachment point 9 equips the pole pot 3; this attachment point is connected to the pole pot 3 by a fastening means 8. The fastening means 8 are designed to allow the position of the third attachment point to be simply modified and, for this purpose, they are in the form of a spindle 9. In the embodiment shown, the fastening means is constituted by a collar 8 (pipe collar) tightly tightened to the pole pot. The neck-

3 lier comporte une vis 10 permettant de régler le diamètre du collier. En desserrant la vis, on peut détacher le collier du pot polaire 3 et le tourner à la fois autour de l'axe longitudinal 7 et le coulisser le long de l'axe longitudinal 7. Ainsi, avec des moyens simples, on peut modifier la posi- tion de la troisième broche 9. En cas de variation des points de fixation à la carrosserie ou si l'orifice correspondant au troisième point de fixation 9 du dispositif d'entraînement d'essuie-glace 1 a une position imprécise, on pourra modifier simplement la position du troisième point de fixation 9. On réalise ainsi une fixation par enfichage, variable, du dis- positif d'entraînement d'essuie-glace. En fonction du mode de réalisation choisi, à la place du collier 8, on peut également envisager d'autres moyens détachables, tels que par exemple un collier à câble que l'on fait passer à travers un orifice de guidage de la troisième broche 9 et tenir ainsi la troisième broche au pot polaire 3. Si l'on utilise un collier à câble, on détruit ce collier lorsqu'on le détache et il faudra alors utiliser un nouveau collier à câble pour fixer la troisième broche 9 dans une position modifiée. 3 bind comprises a screw 10 for adjusting the diameter of the collar. By loosening the screw, it is possible to detach the collar from the pole pot 3 and turn it both around the longitudinal axis 7 and slide it along the longitudinal axis 7. Thus, with simple means, it is possible to modify the position of the third spindle 9. In case of variation of the points of attachment to the bodywork or if the orifice corresponding to the third attachment point 9 of the windscreen wiper drive device 1 has an imprecise position, it will be possible to simply change the position of the third attachment point 9. This provides a variable plugging attachment of the wiper drive device. Depending on the embodiment chosen, instead of the collar 8, it is also possible to envisage other detachable means, such as, for example, a cable collar that is passed through a guide orifice of the third pin 9. and thus hold the third pin to the pole 3. If a cable clamp is used, this collar is destroyed when it is detached and a new cable clamp will then have to be used to fix the third pin 9 in a modified position. .
