Abstract

A motor vehicle windscreen wiper of the type with a windscreen wiper brush which is articulated to a windscreen wiper arm. Moreover, the inventive wiper is of the type in which a connector is inserted longitudinally, from rear to front, inside the front end of the arm, said front end being bent back. Moreover, the connector, which is disposed between the arm and a brush component, has an elastically-deformable element that is used to block said connector in the inserted position. Furthermore, the wiper is of the type in which the connector includes two longitudinal edges which are received between two lateral flanges of the brush component. The invention is characterised in that it includes a safety clasp which is movably mounted between a closed position, in which said clasp extends opposite the blocking element in order to lock the connector in the inserted position, and an open position, which is used to release said connector.

Claims

1. A motor vehicle wiper of the type comprising a wiper blade mounted articulated about a transverse axis on the longitudinal front end of a wiper arm, of the type in which a mounting and articulation connector is interposed between the arm and a blade component, of the type in which the connector is engaged longitudinally from rear to front inside the front end of the arm which is curved longitudinally towards the rear in the form of a U, and in which the connector comprises at least one elastically deformable element for securing the connector in the engaged position inside the front end of the arm, and comprises two longitudinal vertical flanks which are designed to be received between two lateral wings of the blade component,

characterized in that it comprises a safety fastener mounted so as to be able to move between a closed position in which it extends with regards to the securing element in order to prevent its elastic deformation and lock the connector in the engaged position in the arm, and an open position allowing the disengagement of the connector from the hook-shaped end of the arm.

2. The wiper according to claim 1, characterised in that the fastener is mounted movable with respect to the blade component.

3. The wiper according to claim 2, characterised in that the fastener is mounted articulated with respect to the blade component.

4. The wiper according to claim 3, characterised in that the fastener is mounted articulated about a substantially vertical axis of the blade component.

5. The wiper according to claim 4, characterised in that the articulation axis of the fastener is situated close to the front longitudinal end of one wing of the component.

6. The wiper according to claim 2, characterised in that the fastener is held in the closed position by elastic fitting together of complementary shapes.

7. The wiper according to claim 1, characterised in that the securing element is a lug which extends freely and longitudinally towards the front from the front longitudinal end of one flank of the connector, and whose free end comprises a securing nose which extends transversely towards the inside of the connector and which extends with regard to the front face of the front longitudinal end the arm when the connector is in the engaged position.

8. The wiper according to claim 7, characterised in that the fastener forms a cap which extends with regard to, and in a closed position, an external lateral face of the free end of the securing lug of the connector.

9. The wiper according to claim 1, characterised in that the component is an insert piece mounted on a support structure for the wiper rubber of the blade.

10. The wiper according to claim 1, characterised in that the component is a portion of the main yoke of an articulated support structure for the wiper rubber of the blade.

11. The wiper according to claim 1, characterised in that one of the wings of the component of the blade receives, on an external face, and indicator of the aging of the blade which is initially covered with a protective film which is removed, at least partially, automatically, when the fastener is opened.

12. The wiper according to claim 2, characterised in that the securing element is a lug which extends freely and longitudinally towards the front from the front longitudinal end of one flank of the connector, and whose free end comprises a securing nose which extends transversely towards the inside of the connector and which extends with regard to the front face of the front longitudinal end of the arm when the connector is in the engaged position.

13. The wiper according to claim 12, characterised in that the fastener forms a cap which extends with regard to, and in a closed position, an external lateral face of the free end of the securing lug of the connector.

14. The wiper according to claim 3, characterised in that the securing element is a lug which extends freely and longitudinally towards the front from the front longitudinal end of one flank of the connector, and whose free end comprises a securing nose which extends transversely towards the inside of the connector and which extends with regard to the front face of the front longitudinal end of the arm when the connector is in the engaged position.

15. The wiper according to claim 2, characterised in that the component is an insert piece mounted on a support structure for the wiper rubber of the blade.

16. The wiper according to claim 2, characterised in that the component is a portion of the main yoke of an articulated support structure for the wiper rubber of the blade.

17. The wiper according to claim 2, characterised in that one of the wings of the component of the blade receives, on an external face, and indicator of the aging of the blade which is initially covered with a protective film which is removed, at least partially, automatically, when the fastener is opened.

18. The wiper according to claim 3, characterised in that the fastener is held in the closed position by elastic fitting together of complementary shapes.

19. The wiper according to claim 4, characterised in that the fastener is held in the closed position by elastic fitting together of complementary shapes.

20. The wiper according to claim 5, characterised in that the fastener is held in the closed position by elastic fitting together of complementary shapes.
