Abstract

The invention relates to a device ( 2 ) for wiping a window of a motor vehicle, comprising a wiper blade ( 4 ) rotated by a drive shaft ( 6 ) which is arranged at the output of a motor assembly ( 8 ) capable of creating an alternating rotational movement of said drive shaft. The wiping device also comprises means for translating the motor assembly, and some of said drive means are supported by the drive shaft. In this way, it is the rotation of the drive shaft that translates the motor assembly. The invention also relates to a motor vehicle comprising such a wiping device and to a structural element, in particular a boot door, to which the device is attached.

First claim

The invention claimed is:

1. A device for wiping a window of a motor vehicle, comprising:
a wiper arm, including a wiper blade, attached to a drive shaft arranged at the output of a motor assembly for creating an alternating rotational movement of said drive shaft; and
means for driving said motor assembly in translation, a part of said driving means being borne by said drive shaft,
wherein said drive shaft rotates said wiper arm about a first axis of the drive shaft.

2. The device as claimed in claim 1 , wherein said translational driving means comprise means for transforming a rotational movement of the drive shaft about the first axis into a translational movement of this drive shaft along a second axis at right angles to said first axis.

3. The device as claimed in claim 2 , wherein the transformation means comprise a pinion and a rack, the drive shaft bearing said pinion.

4. The device as claimed in claim 3 , wherein the pinion and the rack have straight teeth.

5. The device as claimed in claim 3 , wherein the rack is formed on a plate arranged transversely to the drive shaft.

6. The device as claimed in claim 5 , wherein the rack is formed on an edge of said plate to cooperate with the pinion borne by the drive shaft.

7. The device as claimed in claim 2 , wherein said translational driving means further comprise means for guiding the motor assembly in translation.

8. The device as claimed in claim 7 , wherein the translational guiding means comprise a rail and a carriage, said carriage being secured to the motor assembly and being capable of sliding along said rail, transversely to the first axis of rotation of the drive shaft.

9. The device as claimed in claim 8 , wherein the transformation means comprise a pinion borne by the drive shaft and a rack formed on a plate arranged transversely to the drive shaft, and wherein said plate bears said rail.

10. The device as claimed in claim 9 , wherein the plate is fixed onto a structural element bearing the window to be wiped.

11. The device as claimed in claim 1 , wherein the alternating rotational movement of the drive shaft is performed by a continuously rotating motor assembly and by a mechanical device, which creates this alternation.

12. A structural element of a motor vehicle comprising:
a window;
the wiping device as claimed in claim 1 ; and
a hole through which the drive shaft passes to be on one side of the structural element attached to the wiper arm and to be on another side of the structural element engaged with the motor assembly borne by a plate secured to said structural element, wherein
the hole has an oblong form of axis that is parallel to the direction of sliding of the motor assembly.

13. The structural element of the motor vehicle as claimed in claim 12 , wherein the structural element is a trunk lid.
