Abstract

A motor vehicle wiper including a wiper blade which is articulated to the longitudinal end of a wiper arm via a connector which is articulated on the arm and fixed over a linking portion of the blade, and wherein the linking portion includes two substantially longitudinal and parallel lateral flanges and a transverse element extending between the two flanges and designed to cooperate with a mobile lock borne by the connector for fixing the connector on the blade. The invention is characterized in that the lock is articulated on the connector between a locking position and an unlocking position.

Claims

1. A motor vehicle wiper wherein a wiper blade is articulated to a longitudinal end of a wiper arm by a connector articulated on the arm and fixed over a linking portion of the blade, wherein the linking portion includes two substantially longitudinal and parallel lateral flanges, and a transverse element extending between the two flanges and co-operating with a mobile lock carried by the connector for fixing the connector on the blade, characterized in that the lock is pivoted on the connector between a locking position and an unlocking position.

2. The wiper according to claim 1, wherein the connector is pushed towards a bottom on the linking portion of the blade and in that the lock co-operates with a lower face of the transverse element.

3. The wiper according to claim 1, wherein the lock includes a hooked lug that is rotatingly received between the flanges of the blade and that, in the locking position, co-operates with the transverse element and in the unlocking position, is disengaged in relation to the transverse element.

4. The wiper according to claim 1, wherein the lock includes abutment means for locating the locking and unlocking positions in relation to the connector.

5. The wiper according to claim 1, wherein the lock includes elastic means that force the lock toward either the locking position or the unlocking position.

6. The wiper according to claim 1, wherein said transverse element is a rod, wherein the lock disengages from a locked position when a rear part of the lock is depressed and a hooked lug on the lock disengages from the rod located on the wiper blade permitting detachment of the blade from the connector.

7. A motor vehicle wiper wherein a wiper blade is articulated to a longitudinal end of a wiper arm by a connector articulated on the arm and fixed over a linking portion of the blade, wherein the linking portion includes two substantially longitudinal and parallel lateral flanges, and a transverse element extending between the two flanges and co-operating with a mobile lock carried by the connector for fixing the connector on the blade, characterized in that the lock is articulated on the connector between a locking position and an unlocking position, and the lock is articulated on the connector around a transverse axis.

8. A motor vehicle wiper wherein a wiper blade is articulated to a longitudinal end of a wiper arm by a connector articulated on the arm and fixed over a linking portion of the blade, wherein the linking portion includes two substantially longitudinal and parallel lateral flanges, and a transverse element extending between the two flanges and co-operating with a mobile lock carried by the connector for fixing the connector on the blade, characterized in that the lock is articulated on the connector between a locking position and an unlocking position, and the transverse element is formed by a plate element that extends between the two flanges and is equipped with a longitudinal slit formed in a front transversal edge of the plate element and that, in the unlocking position of the lock, a hooked lug extends opposite from the slit and that, in the locking position, the hooked lug co-operates by pushing against an abutment face of the plate element that is longitudinally arranged behind the slit.

9. A motor vehicle wiper wherein a wiper blade is articulated to a longitudinal end of a wiper arm by a connector articulated on the arm and fixed over a linking portion of the blade, wherein the linking portion includes two substantially longitudinal and parallel lateral flanges, and a transverse element extending between the two flanges and co-operating with a mobile lock carried by the connector for fixing the connector on the blade, characterized in that the lock is articulated on the connector between a locking position and an unlocking position, and the lock includes an elastic lug that extends substantially in a circular arc around an articulation axis of the lock and that includes a cam surface that, when the lock is between the locking and unlocking positions, co-operates with a fixed surface of the connector in order to elastically deform the lug.

10. The wiper according to claim 9, wherein the lock includes a handling plate that extends perpendicular to a transverse axis of the lock.

11. The wiper according to claim 10, wherein the handling plate includes, at a free end, elastic fittings that co-operate with complementary means of the connector for keeping the lock in a locking position.

12. A motor vehicle wiper comprising:

an articulated wiper blade pivotally connected to a longitudinal end of a wiper arm;

a connector positioned over a linking portion of the blade, the linking portion having two substantially longitudinal and parallel lateral flanges;

a transverse element extending between the two flanges of the linking portion; and

a mobile lock carried by the connector and operably associated with the linking portion of the blade for connecting the connector with the blade, the lock pivoting on the connector between locked and unlocked positions.

13. The wiper of claim 12, wherein the connector positioned on the linking portion of the blade is held in position by the lock operably engaging a lower face of the transverse element.

14. The wiper of claim 12, wherein the lock further comprises:

a hooked lug rotatingly received between the flanges of the blade in the locked position the hooked lug rotatingly disengaged from the transverse element in the unlocked position.

15. The wiper of claim 12, wherein the lock further comprises:

abutment means for locating the locked and unlocked positions in relation to the connector.

16. The wiper of claim 12, wherein the lock further comprises:

elastic means for forcing the lock toward either the locked or the unlocked position.

17. The wiper of claim 12, wherein said transverse element is a rod, wherein the lock disengages from a locked position when a rear part of the lock is depressed and a hooked lug on the lock disengages from the rod located on the wiper blade permitting detachment of the blade from the connector.

18. A motor vehicle wiper comprising:

an articulated wiper blade pivotally connected to a longitudinal end of a wiper arm;

a connector positioned over a linking portion of the blade, the linking portion having two substantially longitudinal and parallel lateral flanges;

a transverse element extending between the two flanges of the linking portion; and

a mobile lock carried by the connector and operably associated with the linking portion of the blade for connecting the connector with the blade, the lock pivoting on the connector between locked and unlocked positions, and the lock is articulated on the connector around a transverse axis.

19. A motor vehicle wiper comprising:

an articulated wiper blade pivotally connected to a longitudinal end of a wiper arm;

a connector positioned over a linking portion of the blade, the linking portion having two substantially longitudinal and parallel lateral flanges;

a transverse element extending between the two flanges of the linking portion, the transverse element formed by a plate element having a longitudinal slit formed therein, the plate extending between the two flanges of the wiper blade;

a mobile lock carried by the connector and operably associated with the linking portion of the blade for connecting the connector with the blade, the lock pivoting on the connector between locked position and unlocked positions; and

a hooked lug extending apart from the plate in the unlocked position and the hooked lug engaging an abutment face of the plate element in the locked position.
