Abstract

The invention relates to a connecting device intended to connect a wiper to a motor arm of the wiper, comprising at least one connector ( 7 ) configured to be securely attached to the wiper and an adapter ( 6 ) intended to be received in a terminal part of the motor arm, the adapter ( 6 ) comprising an attachment device ( 13 ) which can move in rotation and is intended to immobilise the adapter ( 6 ) in relation to the terminal part at least longitudinally, characterized in that the connecting device comprises a first device ( 41 ) limiting the mobility of the attachment device ( 13 ) in a first direction of rotation ( 43 ) and a second device ( 42 ) limiting the mobility of the attachment device ( 13 ) in a second direction of rotation ( 44 ) opposite the first direction of rotation ( 43 ).

First claim

The invention claimed is:

1. A connecting device to connect a wiper to a motor arm of the wiper, comprising:
at least one elongated connector extending longitudinally to have opposite terminal ends and configured to be securely attached to the wiper;
an adapter pivotally connected to the at least one connector by a pivot connection about a pivot axis to be received in a terminal part of the motor arm, the adapter comprising an attachment device which moves in rotation and is configured to immobilize the adapter in relation to the terminal part at least longitudinally; and
a first limiting device that limits a mobility of the attachment device in a first direction of rotation and a second limiting device that limits the mobility of the attachment device in a second direction of rotation, opposite the first direction of rotation, wherein
the attachment device comprises a tab that comprises the first limiting device and the second limiting device,
the tab comprises a concave depression disposed between the first limiting device and the second limiting device,
the tab, the first limiting device, and the second limiting device are parts of a monolithic structure, and
a portion of the at least one connector is secured within the concave depression of the tab to immobilize the adapter, said portion is at one of the terminal ends and longitudinally spaced from the pivot axis.

2. The connecting device according to claim 1 , wherein the adapter and the connector are connected by the pivot connection having the pivot axis transverse to a longitudinal axis of the adapter.

3. The connecting device according to claim 2 , wherein the first limiting device limits the mobility of the attachment device when a tensile force is applied to the connector in relation to the terminal part in a direction perpendicular to the pivot axis and passing at least through a member for securing the connector on the wiper.

4. The connecting device according to claim 2 , wherein the second limiting device limits the mobility of the attachment device when a tensile force is applied to the connector in relation to the terminal part in a direction perpendicular to the pivot axis and substantially parallel to the longitudinal axis in which the adapter extends.

5. The connecting device according to claim 1 , wherein the first limiting device is formed of a first side of the tab and by a first surface delimiting the connector.

6. The connecting device according to claim 5 , wherein the first side extends along a longitudinal axis of the adapter, the first surface is an upper surface of the connector provided alongside the first side.

7. The connecting device according to claim 5 , wherein the second limiting device is formed by a second side of the tab which is separate from the first side, and by a second surface delimiting the connector which is separate from the first surface of the connector.

8. The connecting device according to claim 7 , wherein the second side extends in a plane crossing a longitudinal axis of the adapter, the second surface being a lateral surface of the connector provided alongside the second side.

9. The connecting device according to claim 7 , wherein the second side of the tab is in contact with the second surface of the connector when the attachment device and a body of the adapter are turned through an angle of at least 3°, in the second direction of rotation.

10. The connecting device according to claim 5 , wherein the first side of the tab is in contact with the first surface of the connector when the attachment device and a body of the adapter are turned through an angle of at least 3°, in the first direction of rotation.

11. The connecting device according to claim 1 , wherein the attachment device comprises at least one tongue articulated on a body of the adapter, and at an end of which an attachment pad is located.

12. The connecting device according to claim 11 , wherein the attachment pad is configured to grip an upper wall of the terminal part of the motor arm.

13. The connecting device according to claim 12 , wherein the attachment pad comprises at least one tooth extending in a plane parallel to a plane in which the tongue extends, the tooth and the tongue being configured to be located on either side and each opposite the upper wall of the terminal part of the motor arm.

14. The connecting device according to claim 12 , wherein the attachment pad comprises a tooth extending in a plane parallel to a plane in which the rear upper wall extends, the tooth and the rear upper wall being configured to be located on either side and each opposite the upper wall of the terminal part of the motor arm.

15. The connecting device according to claim 1 , wherein the attachment device comprises at least a rear part articulated on a front part of the adapter, the rear part and the front part having a transverse cross section in the shape of a “U”, the rear part and the front part each comprising an upper wall and two side walls originating from the upper wall, an attachment pad emerging from the rear upper wall of the rear part.

16. The connecting device according to claim 15 , wherein at least one rear lateral wall of the rear part is separated from a front lateral wall of the front part by at least onespace, the rear upper wall of the rear part being connected to a front upper wall of the front part by articulation means.

17. A wiper comprising a connecting device according to claim 1 , wherein the connector is of one piece with an element of structure of the wiper.

18. A wiper system comprising a wiper according to claim 17 ; and a rotatable motor arm for the wiper, in which the adapter is housed in a terminal part of the motor arm and held at least longitudinally in this terminal part by the attachment device.

19. The wiper system according to claim 18 , in which the attachment device holds the adapter in the terminal part vertically.
