Abstract

According to the invention, the assembly comprises a mechanical connector provided with two cylindrical protuberances and an adaptor ( 50 ) with two side walls ( 54, 55 ) each having a lateral orifice ( 54 A, 55 A), wherein the end of each cylindrical protuberance has at least one portion which is inclined in relation to the insertion direction of said mechanical connector, towards the inside of the adapter ( 50 ), and a portion ( 54 B) of each side wall ( 54 ) has a cavity ( 54 B), of which at least one inner surface ( 54 C) is inclined in an increasing fashion from the end of said side wall ( 54 ) up to said corresponding lateral orifice ( 54 A), and of which at least one lateral delimitation ( 54 D, 54 E) is inclined in relation to the plane formed by the axis of said corresponding lateral orifice ( 54 A) and said insertion direction, in a decreasing fashion from the end of said side wall ( 54 ) up to said corresponding lateral orifice ( 54 A).

First claim

The invention claimed is:

1. An assembly for a wiping system, said wiping system comprising a blade and an arm which is extended by an end piece, said assembly comprising:
a mechanical connector integral with said blade; and
an adapter able to be connected to said end piece and to said mechanical connector, said adapter comprising two deformable side walls each with a lateral orifice, said mechanical connector comprising two cylindrical protuberances via which said mechanical connector is able to be housed at least partly inside said adapter along an insertion direction, wherein:
an end of at least one cylindrical protuberance has at least one portion which is inclined in relation to said insertion direction, and
at least one side wall has a cavity comprising an inner surface which is inclined in increasing fashion from an end of said side wall up to said corresponding lateral orifice,
wherein the cavity comprises lateral delimitations which are inclined in relation to the plane formed by the axis of said corresponding lateral orifice and said insertion direction, in a decreasing fashion from the end of said side wall up to said corresponding lateral orifice.

2. The assembly according to claim 1 , wherein the lateral orifices of the adapter are arranged facing each other on a common axis.

3. The assembly according to claim 2 , wherein the cylindrical protuberances of the mechanical connector are arranged facing each other on a common axis, which lies parallel to the common axis of the lateral orifices of the adapter.

4. The assembly according to claim 1 , wherein the cylindrical protuberances of the mechanical connector and the lateral orifices of the adapter each have a circular cross-section.

5. The assembly according to claim 1 , wherein the inner inclined surface of the cavity provided in each side wall and lateral delimitations of said cavity are symmetrical in relation to a plane passing through the axis of the corresponding lateral orifice and the insertion direction of said cylindrical protuberances.

6. The assembly according to claim 1 , wherein the deformable nature of at least one side wall results from at least one groove provided in the thickness of the side wall.

7. The assembly according to claim 1 , wherein
each cylindrical protuberance being able to be inserted in the corresponding lateral orifice along a predefined insertion direction by deformation of the corresponding side wall, wherein
the end of each cylindrical protuberance has at least one portion which is inclined in relation to said insertion direction, towards the inside of said adapter, and
wherein the portion of each side wall, on which the corresponding cylindrical protuberance is intended to rest when inserted in the corresponding lateral orifice, has a cavity, at least one inner surface of which is inclined in an increasing fashion from the end of said side wall up to said corresponding lateral orifice, and of which at least one lateral delimitation is inclined in relation to the plane formed by the axis of said corresponding lateral orifice and said insertion direction, in decreasing fashion from the end of said side wall up to said corresponding lateral orifice.

8. An assembly for a wiping system, said wiping system comprising a blade and an arm which is extended by an end piece, said assembly comprising:
a mechanical connector integral with said blade; and
an adapter able to be connected to said end piece and to said mechanical connector, said adapter comprising two deformable side walls each with a lateral orifice, said mechanical connector comprising two cylindrical protuberances via which said mechanical connector is able to be housed at least partly inside said adapter along an insertion direction, wherein:
an end of at least one cylindrical protuberance has at least one portion which is inclined in relation to said insertion direction, and
at least one side wall has a cavity comprising an inner surface which is inclined in increasing fashion from an end of said side wall up to said corresponding lateral orifice,
wherein the mechanical connector comprises a central part from which the two cylindrical protuberances protrude, a cylindrical shoulder being interposed between the central part and each cylindrical protuberance.

9. An assembly for a wiping system, said wiping system comprising a blade and an arm which is extended by an end piece, said assembly comprising:
a mechanical connector integral with said blade; and
an adapter able to be connected to said end piece and to said mechanical connector, said adapter comprising two deformable side walls each with a lateral orifice, said mechanical connector comprising two cylindrical protuberances via which said mechanical connector is able to be housed at least partly inside said adapter along an insertion direction, wherein:
an end of at least one cylindrical protuberance has at least one portion which is inclined in relation to said insertion direction, and
at least one side wall has a cavity comprising an inner surface which is inclined in increasing fashion from an end of said side wall up to said corresponding lateral orifice,
wherein the adapter comprises at least two locking elements, each consisting of a telescopic button arranged at one end of a flexible tab, to lock the adapter in relation to the end piece, said tabs being arranged so as to overlap on operation of the telescopic buttons.
