Abstract

The invention relates to an adapter for a wiper blade mounting, the adapter comprising a cover which can be releasably attached to a main bar of the mounting by a single rotational movement that allows form-closure engagement between the cover and the main bar. According to the invention, the cover comprises an angular indexing system for defining an axis of rotation of the cover, the angular indexing system cooperating with an opening in the main bar. The opening and the angular indexing system have an asymmetrical form in order to allow angular indexing of the cover relative to the main bar and, subsequently, mechanical coupling of the cover on the main bar. The invention is applicable to motor vehicles.

First claim

What is claimed is:

1. An adapter for fastening a wiper blade mounting on an articulated wiper blade arm, the adapter comprising:
a cover configured so that it can be removably fastened to a main cross-bar of the wiper blade mounting;
a device for assembling the cover on the main cross-bar of the wiper blade mounting; and an assembly device comprising an angular indexing system configured to allow the assembly of the cover on the main cross-bar by rotating said cover relative to said main cross-bar, the angular indexing system comprising:
a shaft that extends protruding relative to a bearing face of the cover, and
a vertical locking member situated at a free end of the shaft of the angular indexing system, the vertical locking member being configured to adopt:
a first angular configuration in which the vertical locking member allows the insertion of the cover into the main cross-bar; and
a second angular configuration in which the vertical locking member allows the rigid connection of the cover to the main cross-bar.

2. The adapter as claimed in claim 1 , in which the vertical locking member of the angular indexing system comprises:
a first boss that extends perpendicularly relative to the shaft of said angular indexing system;
a second boss that extends perpendicularly relative to the shaft of said angular indexing system.

3. The adapter as claimed in claim 2 , in which the vertical locking member of the angular indexing system comprises a locking face situated facing the bearing face of the cover, and/or the first and second bosses of the vertical locking member of the angular indexing system are longitudinally delimited by a circular face.

4. The adapter as claimed in claim 2 , in which the first boss is prismatic and laterally delimited by two flat, parallel lateral sides, and/or the second boss is laterally delimited by two flat lateral edges forming an angle of between 20° and 45°.

5. The adapter as claimed in claim 1 , in which the angular indexing system comprises a lateral keying member configured to allow the lateral alignment of the cover on the main cross-bar, said lateral keying member of the angular indexing system comprising:
a first lateral stop situated on a first lateral side of the cover; and
a second lateral stop situated on a second lateral side opposite the first lateral side of the cover.

6. The adapter as claimed in claim 5 , in which each lateral stop forming the lateral keying member of the angular indexing system takes the form of a tab having an L-shaped transverse profile, said lateral stop comprising:
a longitudinally extending boss that extends protruding from the bearing face of the cover; and
a lip situated at a distal end of the longitudinally extending boss, said lip extending laterally relative to said longitudinally extending boss.

7. The adapter as claimed in claim 6 , in which the lip of each lateral stop extends towards the opposite lateral side of the cover and/or comprises a locking surface situated facing the bearing face of the cover.

8. A wiper blade for a motor vehicle comprising:
an adapter as claimed in claim 1 ;
a wiper blade mounting, the mounting comprising:
a main cross-bar to which the adapter is removably fastened;
two secondary cross-bars fastened to the main cross-bar and supporting a wiper rubber.

9. The wiper blade as claimed in claim 8 , in which the main cross-bar comprises a bearing platform against which the bearing face of the cover is pressed, said bearing platform of the main cross-bar comprising an opening configured to allow the engagement of the shaft and the vertical locking member of the angular indexing system.

10. The wiper blade as claimed in claim 9 , in which the main cross-bar comprises a recess for indexing the cover of the adapter relative to said main cross-bar, the indexing recess being radially delimited by a cylindrical wall and vertically delimited by the bearing platform.

11. The wiper blade as claimed in claim 9 , in which the angular indexing system comprises a lateral keying member configured to allow the lateral alignment of the cover on the main cross-bar, said lateral keying member of the angular indexing system comprising a first lateral stop situated on a first lateral side of the cover, and a second lateral stop situated on a second lateral side opposite the first lateral side of the cover, and in which the bearing platform comprises:
a first lateral keying recess interacting with the first lateral stop of the lateral keying member, the first lateral keying recess being situated in a first lateral edge of the bearing platform; and
a second lateral keying recess interacting with the second lateral stop of the lateral keying member, the second lateral keying recess being situated in a second lateral edge opposite the first lateral edge of the bearing platform.

12. The wiper blade as claimed in claim 11 , in which each lateral keying recess interacting with the keying member of the angular indexing system of the cover of the adapter is delimited by:
a lower surface situated vertically at a distance from the bearing platform that is greater than the distance vertically separating the lower face of the lateral keying member of the cover from the bearing face of said cover; and/or
a lateral bearing surface situated set back relative to the lateral edge of the bearing platform, said lateral bearing surface of each lateral keying recess being suitable for being pressed against the lateral bearing face of the lip of each lateral stop forming the lateral keying member of the angular indexing system of the cover of the adapter; and/or
two longitudinal edges allowing the insertion of the lateral keying member of the angular indexing system of the cover of the adapter into the corresponding lateral keying recess, by a rotating movement about the shaft of said angular indexing system.
