Abstract

The invention proposes an adapter (26) for a wiper (10) comprising a body (25) of elongate shape which is shaped to be mounted in a complementary yoke (28) of inverted U-shaped cross section belonging to a wiper arm, characterized in that the body (1025) of the adapter (1026) comprises at least one elastic tab (1132a, 1132b) which is deformable in the transverse direction so as to retract as the adapter (1026) is being assembled and/or dismantled with respect to the yoke (28), the elastic tab (1132a, 1132b) being borne by a lateral wall (1026a, 1026b) of the body (1025) of the adapter.

First claim

The invention claimed is:

1. An adapter for a wiper of a motor vehicle, comprising:
a body of longitudinally elongate shape which is delimited by two vertical longitudinal lateral walls which are transversely opposite and joined together by a horizontal upper wall, the body being shaped to be mounted in a complementary yoke of inverted U-shaped cross section belonging to a wiper arm,
wherein the body of the adapter comprises at least one elastic tab which is deformable in a transverse direction so as to retract as the adapter is being assembled and/or dismantled with respect to the yoke, the at least one elastic tab is delimited by at least one slot formed in the two vertical longitudinal lateral walls of the body of the adapter,
wherein the body of the adapter comprises at least two longitudinally arranged retention tabs, each of which extends longitudinally forwards from a front longitudinal end in continuation of an associated lateral wall of the two vertical longitudinal lateral walls of the body of the adapter,
wherein the at least two retention tabs retain the adapter in a rearwards longitudinal direction, and
wherein the at least two retention tabs each comprise a chamfer, formed on a lower edge of the respective retention tab, which engages in complimentary recesses of an end piece of the yoke.

2. The adapter according to claim 1 , wherein the at least one elastic tab bears a longitudinal retention lug configured to collaborate with the yoke and/or a component borne by the yoke.

3. The adapter according to claim 2 , wherein the retention lug has a retractable cam profile able to collaborate with the yoke or a component borne by the yoke, the cam profile being a profile having two opposite slopes for mounting and dismantling respectively.

4. The adapter according to claim 2 , wherein the at least one elastic tab extends longitudinally, and the retention lug is formed at a front free end of the elastic tab.

5. The adapter according to claim 1 , further comprising at least one front stud which extends transversely projecting outwards and which is arranged on a front part of a lateral wall of the body, the at least one front stud being configured to collaborate with a component borne by the yoke or with the yoke so as to guarantee that this component is in a determined longitudinal position with respect to the yoke.

6. The adapter according to claim 1 , further comprising at least one rear stud which extends transversely projecting outwards and which is arranged on a rear part of a lateral wall of the body, the at least one rear stud being configured to collaborate with the yoke to provide longitudinal retention of the adapter in the forward direction with respect to the yoke.

7. The adapter according to claim 1 , wherein, at the front longitudinal end, the body of the adapter comprises at least one convex curved stop surface for longitudinally positioning the adapter with respect to the yoke or a component borne by the yoke.

8. The adapter according to claim 7 , wherein the at least one convex curved stop surface has an upper transverse edge which is longitudinally offset forwards with respect to a lower transverse edge of the at least one convex curved stop surface.

9. The adapter according to claim 7 , wherein the at least one convex curved stop surface is able to come to bear longitudinally against an opposing portion of the yoke or of a component borne by the yoke so as to guide assembly of the adapter in the yoke or in the component borne by the yoke.

10. The adapter according to claim 7 , wherein the at least one convex curved stop surface is formed at the front longitudinal end of an associated longitudinal lateral wall of the body of the adapter.

11. The adapter according to claim 1 , further comprising at least one tab for longitudinal retention of the body of the adapter with respect to the yoke or a component borne by the yoke, which extends longitudinally rearwards and is shaped to collaborate with the yoke or a component borne by the yoke.

12. The adapter according to claim 1 , wherein the body of the adapter comprises a locking tab which:
extends vertically projecting above an upper face of the body, is configured to be received through a hole in the yoke,
bears a rear contact surface for contact with an edge of the hole in the yoke; and
is connected to the body of the adapter by a vertical connecting part which is able to deform elastically so as to allow a longitudinal movement of the rear contact surface.

13. An assembly comprising:
a wiper arm; and
an adapter according to claim 1 ,
wherein the yoke is equipped with a front cap which covers the yoke and is opened vertically downwards, the cap being mounted with the ability to slide longitudinally on the yoke.

14. A motor vehicle wiper comprising:
a wiper blade to wipe a window of the vehicle; and
a connection assembly to connect the wiper blade to a drive arm, the connection assembly comprising at least one adapter according to claim 1 .
