Abstract

System for cleaning a glazed surface of a motor vehicle, including at least one wiper and a drive device for driving at least the wiper along an axis of translation, substantially perpendicular to said wiper, where the glazed surface is a detection surface of a sensor/emitter of a detection assembly and in that the drive device includes at least one drive motor driving in rotation about an axis of rotation substantially perpendicular to the axis of translation, and at least a conversion device converting a rotational movement of the drive motor into a rectilinear movement along the axis of translation.

First claim

What is claimed is:

1. A cleaning system for cleaning a glazed surface of a motor vehicle, comprising at least one wiper and a drive device for driving the at least the wiper along an axis of translation substantially perpendicular to the at least one wiper, with the drive device connected to the at least one wiper between the at least one wipers axial ends, with the at least one wiper including at least one guide member for guiding the wiper along the axis of translation positioned at one of the axial ends, wherein the glazed surface is a detection surface of a sensor or transmitter of a detection assembly and in that the drive device includes at least one drive motor for driving in rotation about an axis of rotation substantially perpendicular to the axis of translation, and at least one conversion device for converting the rotary movement of the drive motor into a rectilinear movement along the axis of translation.

2. The cleaning system as claimed in claim 1 , wherein the conversion device includes an articulated connecting member to which the wiper is attached, by means of at least one connector.

3. The cleaning system as claimed in claim 2 , wherein the connector is centered on the wiper.

4. The cleaning system as claimed in claim 1 , wherein the conversion device includes at least a connecting rod system and a cam.

5. The cleaning system as claimed in claim 4 , wherein the connecting rod system includes at least a first connecting rod, attached to the drive motor to form a fixed motor articulation point, and at least two articulated quadrilaterals of connecting rods, respectively a first quadrilateral of connecting rods and a second quadrilateral of connecting rods, an articulated connecting member being common to the first quadrilateral and to the second quadrilateral, the second quadrilateral including a fixed point of the conversion device.

6. The cleaning system as claimed in claim 1 , wherein a connector is arranged at a first axial end of the wiper, the at least one guide member being arranged at a second axial end, opposite the first axial end, of the at least one wiper.

7. The cleaning system as claimed in claim 1 , wherein the conversion device includes a fixed motor articulation point rotationally rigidly secured to an output shaft of the drive motor.

8. The cleaning system as claimed in claim 1 , wherein the conversion device includes at least a connecting rod system or a cam.

9. A detection assembly for a motor vehicle, the detection assembly comprising at least one sensor or transmitter, with the at least one sensor or transmitter including at least one glazed surface, and at least one cleaning system, with the cleaning system including at least one wiper and a drive device for driving the at least the wiper along an axis of translation substantially perpendicular to the at least one wiper, with the drive device connected to the at least one wiper between the at least one wipers axial ends, with the at least one wiper including at least one guide member for guiding the wiper along the axis of translation positioned at one of the axial ends, wherein the glazed surface is a detection surface of a sensor or transmitter of a detection assembly and in that the drive device includes at least one drive motor for driving in rotation about an axis of rotation substantially perpendicular to the axis of translation, and at least one conversion device for converting the rotary movement of the drive motor into a rectilinear movement along the axis of translation.

10. The detection assembly as claimed in claim 9 , wherein a main dimension of a blade of the at least one wiper is substantially equal to one of the dimensions, longitudinal or transverse, of the at least one glazed surface to be cleaned.

11. The detection assembly as claimed in claim 9 , wherein the at least one glazed surface to be cleaned is curved, the at least one glazed surface being defined by at least a directrix and a generatrix, the axis of translation of the wiper extending parallel to at least the generatrix of the glazed surface of the sensor or transmitter.

12. A cleaning system for cleaning a glazed surface of a motor vehicle, comprising at least one wiper and a drive device for driving the at least the wiper along an axis of translation substantially perpendicular to the at least one wiper, wherein the glazed surface is a detection surface of a sensor or transmitter of a detection assembly and in that the drive device includes at least one drive motor for driving in rotation about an axis of rotation substantially perpendicular to the axis of translation, and at least one conversion device for converting the rotary movement of the drive motor into a rectilinear movement along the axis of translation, with the conversion device including at least a first connecting rod, attached to the drive motor to form a fixed motor articulation point, and at least two articulated quadrilaterals of connecting rods, respectively a first quadrilateral of connecting rods and a second quadrilateral of connecting rods, an articulated connecting member being common to the first quadrilateral and to the second quadrilateral, the second quadrilateral including a fixed point of the conversion device.
