Abstract

The present invention relates to a wiper system for a glazed surface, with at least one main body which includes at least one blade rubber designed to come into contact with the glazed surface and at least one embedded motorized member for setting in motion, which is configured to drive a linear movement of the main body along the glazed surface.

First claim

What is claimed is:

1. A wiper system for a glazed surface, comprising
a main body which includes a blade rubber designed to come into contact with the glazed surface;
a motorized member for providing actuating motion, with the motorized member being configured to drive a linear movement of the main body along the glazed surface;
the motorized member including an electric motor and a toothed wheel, the toothed wheel in engagement with a notched belt; and
a pressing member for pressing the blade rubber against the glazed surface, the pressing member being borne by the notched belt.

2. The wiper system of claim 1 , wherein the motorized member includes
the electric motor, wherein the main body includes an electrical energy storage device configured to supply electrical energy to the electric motor.

3. The wiper system of claim 2 , wherein the main body includes a connector electrically connected to the electrical energy storage device, and wherein the wiper system further includes a charging terminal configured to be electrically connected to the connector.

4. The wiper system of claim 1 , wherein the pressing member takes the form of an elastic return device designed to press the notched belt against the glazed surface.

5. The wiper system of claim 1 , further including
a fixed guide means for the main body, wherein the fixed guide means is formed by the notched belt; the toothed wheel designed to be driven in rotation by the electric motor.

6. The wiper system of claim 5 , wherein the pressing member includes an elastic return device designed to stretch the notched belt, and wherein the toothed wheel in engagement with the notched belt is arranged between the notched belt and the glazed surface.

7. The wiper system of claim 5 , further including a tensioning member for tensioning the notched belt, which tensioning member is arranged upstream of the toothed wheel with respect to a direction of displacement of the main body along the glazed surface.

8. The wiper system of claim 1 , further including a fixed guide means for the main body, wherein the blade rubber is configured to be pressed against a front face of the glazed surface, wherein the fixed guide means includes a gutter formed on the front face of the glazed surface, and wherein the member for setting in motion includes the electric motor designed to drive the rotation of a rolling member received in the gutter.

9. The wiper system of claim 8 , further including the pressing member for pressing the blade rubber against the glazed surface;
the pressing member being borne by the main body includes a hook which defines a housing in which a roller is received;
the pressing member including an elastic return member, which is stretched between two pins borne by the hook and is in contact with a shaft of the roller;
the shaft of the roller configured to be movable along an oblong hole formed in an upper wall of the hook, which contributes to defining the housing, under a return effect of the elastic return member such that the blade rubber borne by the main body bears against the front face of the glazed surface.

10. A driving assistance device comprising:
a detection module and a wiper system, wherein the detection module includes a driving assistance sensor and
a glazed surface closing the detection module and protecting the driving assistance sensor, and
the wiper system including a main body, which includes a blade rubber adapted to contact the glazed surface and a motorized member for providing actuating motion, with the motorized member being configured to drive a linear movement of the main body along the glazed surface;
the motorized member including an electric motor and a toothed wheel, the toothed wheel in engagement with a notched belt; and
a pressing member for pressing the blade rubber against the glazed surface, the pressing member being borne by the notched belt.
