Abstract: The invention relates to a member 24 for a system for connecting a wiper blade to a windscreen wiper arm, comprising means 80 of articulation about an axis Y of pivoting and configured in order to interact with complementary means of a second member of the connection system, characterized in that the articulation means comprise at least one hole 80 comprising at least two portions 80a, 80b of a cylinder having radii R1, R2, which are constant and different, each cylinder forming a rotation bearing.

Abstract: Adapter (26) for a windscreen wiper, in particular a motor vehicle windscreen wiper, said adapter being intended to connect a wiper blade to an end part (28) of a driving arm, which has a substantially U-shaped cross section, said adapter comprising a body configured to be inserted into said end part such that said body extends at least in part between two substantially parallel lateral legs (32a, 32b) of the end part, characterized in that said adapter also comprises two substantially parallel lateral walls (52a, 52b) which extend on either side of said body and which are spaced apart laterally from said body in order to allow the lateral legs of the end part to be fitted between said body and said lateral walls, and in that the lateral spacings between the body and said lateral walls are designed to receive at least two end parts (28) of arms having different lateral dimensions.

Abstract: The invention relates to a connection device B for mechanically linking a wiper blade A to a windscreen wiper drive arm C, C? of a motor vehicle, said connection device (B) includes a connector 2 designed to be rigidly attached to the wiper blade A and an adaptor 3 designed to connect the connector 2 to an end part 5, 5? of the drive arm C, C?, in which the connector 2 includes at least one hole 24 of circular section through which the axis of rotation Y between the wiper blade A and the drive arm C, C? passes, the hole 24 in the connector being delimited by at least one flank 23 of the connector 2 and the adaptor 3 having at least one through-seat 40, 40? into which at least a portion of the flank 23 extends.
