Abstract

Adapter (29) for a connection device (7) configured to connect a wiper blade (3) to a drive arm (5) in a wiper system (1) for a motor vehicle, comprising a first lateral wall (43) and a second lateral wall (45) distant from one another and connected to one another by an upper wall (46), the first lateral wall (43) and the second lateral wall (45) respectively comprising a first orifice (47) and a second orifice (49) which are suitable for receiving a pin (23) extending in a transverse direction (Oy) projecting from the drive arm (5), characterized in that the second lateral wall (45) comprises at least one attachment means (57) for attaching the pin (23) in the second orifice (49) configured to hold the adapter (29) secured to the drive arm (5) at least in the transverse direction (Oy).

First claim

The invention claimed is:

1. An adapter for a connection device configured to connect a wiper blade to a drive arm in a wiper system for a motor vehicle, comprising:
a first side wall and a second side wall spaced apart from each other and connected to each other by a top wall,
the first side wall and the second side wall comprising respectively a first orifice and a second orifice that are designed to receive a pin projecting from the drive arm in a transverse direction,
wherein the second side wall comprises at least one fastening means for fastening the pin in the second orifice configured to rigidly connect the adapter to the drive arm at least in the transverse direction,
wherein the at least one fastening means comprises a narrowing portion of the second orifice, the second orifice having a substantially frustoconical shape and being defined by at least a first principal dimension of the second orifice and a second principal dimension of the narrowing portion, measured respectively at an inner face and an outer face of the second side wall, the first principal dimension being greater than the second principal dimension.

2. A connection device configured to connect a wiper blade to a drive arm in a wiper system for a motor vehicle, the connection device comprising:
at least one connector configured to be rigidly connected to the wiper blade and including at least one transverse hole configured to receive a pin; and
an adapter as claimed in claim 1 that is mounted pivotingly about a rotation axis on the connector to link the connector to the drive arm.

3. A wiper system for a motor vehicle comprising:
a wiper blade;
a drive arm; and
a connection device as claimed in claim 2 ,
the drive arm having at least one pin and one lug, both of which project from an end portion of the drive arm in a transverse direction.

4. The wiper system as claimed in claim 3 , in which the end portion of the drive arm has at least a first flank and a second flank, at least the second flank carrying the pin and the second flank bearing at least partially against an outer face of the first side wall of the adapter.

5. The wiper system as claimed in claim 3 , in which the lug includes at least one end stop flange for the adapter arranged opposite the second side wall of the adapter.

6. The wiper system as claimed in claim 5 , in which the lug is defined by a transverse dimension, measured between the second flank and an inner surface of the end flange, the transverse dimension being strictly greater than a corresponding transverse dimension of the adapter measured between an outer face of the first side wall and the outer face of the second side wall, the inner surface of the end flange being arranged at a non-zero distance from the outer face of the second side wall of the adapter.

7. A motor vehicle having a wiper system as claimed in claim 3 .
