A method for washing a window of a vehicle, using at least one wiper blade member and a liquid projector that projects liquid for washing the window onto a wiping surface has a first wiping cycle including a first step of actuating the wiper blade member to move over the window in a first direction from a first starting position to a wiping end position, while projecting the liquid onto the wiping surface, and a second step of actuating the wiper blade member to move over the window in a second direction opposite the first direction from the wiping end position to the first starting position, and a second wiping cycle including a third step of actuating the wiper blade member to move over the window in the first direction from the first starting position to the wiping end position, while projecting the liquid onto the wiping surface.

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 R.sub.1, R.sub.2, which are constant and different, each cylinder forming a rotation bearing.

Adapter for a windscreen wiper, in particular a motor vehicle windscreen wiper, said adapter being intended to connect a wiper blade (12) to an end piece (28) of a first driving arm (14), of the laterally locking type that is secured to a cylindrical rod (33) that defines an articulation axis of the adapter with respect to said blade, said adapter comprising a longitudinal body comprising two substantially parallel first longitudinal lateral wall that are connected together by a transverse wall, said body being connected at one longitudinal end to a cowling (46) that has a transverse dimension larger than said body, characterized in that said body has, at a longitudinal distance from said cowling, a transverse orifice (45) configured to receive said cylindrical rod, and in that said cowling comprises, on a first side of said adapter, a lateral face configured to cooperate with said end piece by bearing.

A wiper unit for an automobile windshield wiper system has at least one wiper arm connectable to a wiper drive of the windshield wiper system and at least one wiper blade supported by the wiper arm. In order to provide a lightweight wiper unit that can be produced cost-effectively and offers greater design freedom, at least one fiber-reinforced nonmetallic strip is arranged on the outside of the wiper arm and/or the wiper blade. That nonmetallic strip extends over at least half the length of the wiper arm or wiper blade, is connected to the wiper arm or the wiper blade in a substance-bonded manner, and is arranged at least in part on a side of the wiper arm or wiper blade which is arranged facing or facing away from an automobile windshield which is to be wiped.

The invention relates to an adapter 26 for connecting a wiper blade 12 to a driving arm, the adapter comprising two lateral longitudinal walls 42a, 42b spaced apart from one another so as to form therebetween at least one housing 45 configured in order to receive at least in part a connector 24 of the wiper blade, at least one of the lateral walls 42a, 42b comprising at least one hole 56, said lateral wall 42a, 42b further comprising a bearing means 54, 54a projecting from an external face 75 of the lateral wall 42a, 42b, characterized in that the bearing means 54, 54a is traversed by at least one hole 56, said bearing means 54, 54a being made as one with the external face 75 of the lateral wail 42a, 42b.

A wiper blade is presented having a wiper strip, a primary frame, and a pair of secondary frames. The primary frame having a connection device capable of connecting the wiper blade to a wiper arm disposed on a top side of the primary frame, and a connection structure disposed, on opposite ends of the primary frame. The pair of secondary frame, each have a central pivot connection portion and two leg portions extending from the central pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames wherein the pivot structure of the secondary frames are connected to the connection structures on the ends of the primary frame. A wiper blade is also presented having a wiper strip, a force distribution structure having opposite ends, and a cover.

A wiper apparatus having an improved structure between a wiper arm tip and a vertebra includes a vertebra having a rod shape and providing elastic resilience to a wiper strip, a connector fixed to the vertebra; and a wiper arm detachably coupled to the connector. The position of the vertebra is above a lower end of an arm tip formed on a free end portion of the wiper arm.

A wiper arm for use with a wiper blade, which is mechanically and detachably connectable to the wiper arm and to a wiper arm adapter by joining in an assembly direction using a wiper blade adapter, includes an electrical connecting element, disposed on a wiper arm side of the wiper blade adapter, configured to reversibly establish a connection to a second electrical connecting element on a wiper blade side of the wiper blade adapter. The connection between the electrical connecting element and the second electrical connecting element is formed along the assembly direction. The electrical connecting element and the second electrical connecting element are mounted floating. The electrical connecting element and the second electrical connecting element are mounted deflectable in a spatial plane oriented crossways to the assembly direction.

A longitudinal member for retaining a stiffening spine and holding a wiper blade for a windscreen wiper of a window of a motor vehicle is disclosed. The member defines at least one longitudinal housing for receiving the spine and at least one longitudinal housing for receiving a heel of the wiper blade, at least one of the housings being delimited at least partly by a bottom wall and two side walls linked to the bottom wall, where the side walls have planar inner faces converging towards one another away from the bottom wall.
