Abstract

The invention relates to an adapter intended to connect a wiper blade ( 7 ) to a drive arm ( 5 ) of a wiper system ( 800 ) for a vehicle, the adapter (IO 0 ) comprising a head (I) and a body ( 2 ), the adapter (IO 0 ) being formed by an upper wall (IO, 20 ) and two lateral flanks (I la, I lb, 2 la, 2 lb ), the adapter (IO 0 ) comprising a centring means ( 3 ) for centring in a vertical direction (Oz) perpendicular to the upper wall (IO, 20 ), characterised in that the centring means ( 3 ) is extended longitudinally by a guide member ( 9 ) configured to be engaged with the drive arm ( 5 ), the adapter (IO 0 ) comprising a tab ( 4 ) configured to wedge the adapter (IO 0 ) in the vertical direction (Oz). The invention is applicable to motor vehicles.

First claim

1 . An adapter configured to connect a windshield wiper to a drive arm of a wiper system for a vehicle, the adapter comprising:
a head and a body which extend in the continuation of one another in a longitudinal direction of the adapter, the adapter being formed at least by an upper wall and at least by two lateral flanks extending from the upper wall; at least one centering means configured to center it with respect to the drive arm in a vertical direction perpendicular to the upper wall, wherein the centering means is continued longitudinally along the body by a guide member configured to be engaged with the drive arm; and a tongue configured to wedge the adapter in the vertical direction (Oz).

2 . The adapter as claimed in claim 1 , wherein the tongue is formed integrally with the body and/or with the guide member.

3 . The adapter as claimed in claim 1 , wherein the guide member is carried by a lateral flank of the body of the adapter.

4 . The adapter as claimed in claim 1 , wherein the centering means and the guide member are disposed beyond a shoulder formed at a boundary between the head and the body.

5 . The adapter as claimed in claim 1 , wherein the tongue is carried by a lateral flank of the body of the adapter.

6 . The adapter as claimed in claim 1 , wherein the guide member comprises an upper edge face and a lower edge face on the opposite side from the upper edge face, the upper edge face being disposed between the upper wall of the adapter and the lower edge face, the tongue extending between the upper wall of the adapter and the upper edge face.

7 . The adapter as claimed in claim 1 , wherein the guide member comprises a first longitudinal end joined to the centering means and a free second longitudinal end at the opposite end from the first longitudinal end, the tongue converging toward the second longitudinal end.

8 . The adapter as claimed in claim 1 , wherein the tongue is able to deform plastically.

9 . The adapter as claimed in claim 6 , wherein the lower edge face of the guide member is continued by an insertion chamfer that forms an angle (α) of between 20° and 60° with the lower edge face.

10 . The adapter as claimed in claim 4 , wherein the centering means is a half-disk, the center of which passes through a plane containing the shoulder.

11 . A connection device comprising:
an adapter as claimed in claim 1 ; and a connector that is able to be secured to a windshield wiper, wherein the adapter and the connector are connected by a means for rotational connection.

12 . A windshield wiper comprising a connection device as claimed in claim 11 .

13 . A wiper system comprising:
a windshield wiper; a drive arm; and an adapter as claimed in claim 1 , wherein the adapter cooperates with a yoke of the drive arm, wherein the centering means is disposed in an aperture arranged in a lateral wall of the yoke, the tongue extending into the aperture to wedge the adapter in the vertical direction with respect to the yoke.
