The invention relates to a drive arm for driving a wiper blade intended for a motor vehicle, the drive arm extending in a longitudinal direction (X), the drive arm comprising at least one first attachment means (224) for a first end of an elastic return device and at least one second attachment means (234) for the first end of the elastic return device, characterized in that a first distance (d1) measured parallel to the longitudinal direction (X) between the first attachment means (224) and the second attachment means (234) is not zero.

The invention relates to a mounting bracket (5) for a pipe (4) supplying fluid to a driving arm (1) of a motor vehicle wiper system (100), the driving arm (1) comprising at least one spring (14), the mounting bracket (5) comprising at least one sleeve (51) configured to hold the supply pipe (4). The mounting bracket (5) according to the invention comprises a substantially hollow cylindrical body (50) linked to the sleeve (51) and configured to be inserted into a space (141) surrounded by the spring (14) of the driving arm (1). The invention also relates to a driving arm (1) comprising such a mounting bracket (5) and to a method for assembling such a driving arm (1), comprising a preliminary step of inserting the body (50) of such a mounting bracket (5) into at least part of the aforementioned space (141).

The invention relates to a wiper arm device with an integrally formed wiper arm element (10) which is provided with a fastening part (12) for articulated connection and which has at least one wiper arm element portion (14) with a longitudinal extent of at least 10% of the total longitudinal extent of the wiper arm element (10). According to the invention, it is proposed that the wiper arm element portion (14) has a cross-section that differs from an at least substantially U-shaped cross-section.

A wiper assembly includes a bent arm providing a channel. The bent arm is configured to connect to a shaft of an actuator. The wiper assembly additionally includes a wiper blade slidably received within the channel. A method includes securing a bent arm to a shaft of an actuator, and biasing a wiper blade against a window during the securing.

A wiper arm includes a spring for applying a biasing force to the rotation of an arm main body with respect to an arm head and enables the thickness of the wiper arm to be thinner while ensuring the suitable biasing force. The wiper arm also includes a coil spring and a spring plate. The arm main body includes a hinge block rotatably connected to the arm head through a hinge pin and a shaft section extending from the hinge block. The spring plate includes a front end wall including an insertion hole into which the shaft section is inserted and leg sections rotatably attached to the arm head through a roller pin. The coil spring is disposed to be coaxial with the shaft section and is held to be sandwiched between the front end surface of the hinge block and the front end wall of the spring plate.

A wiper arm and a windscreen wiper system, wherein the wiper arm comprises a joint part and a lever part and a spring, wherein the parts form a common joint. The spring is embodied here as a torsion spring.

There is provided a wiper arm which includes biasing means for applying a suitable biasing force to the rotation of an arm main body with respect to an arm head and enables the thickness of the wiper arm to be thinner while ensuring the suitable biasing force. A wiper arm 1 includes an arm head 2, an arm main body 3, a coil spring 4, and a spring plate 5. The arm main body 3 includes a hinge block 21 rotatably connected to the arm head 2 through a hinge pin 15 and a shaft section 22 extending from the hinge block 21. The spring plate 5 includes a front end wall 31 including an insertion hole 33 into which the shaft section 22 is inserted and leg sections 32A, 32B which are rotatably attached to the arm head 2 through a roller pin 18. The coil spring 4 is disposed to be coaxial with the shaft section 22 and is held to be sandwiched between the front end surface 21c of the hinge block 21 and the front end wall 31 of the spring plate 5.

The invention relates to a wiper arm device with an integrally formed wiper arm element (10) which is provided with a fastening part (12) for articulated connection and which has at least one wiper arm element portion (14) with a longitudinal extent of at least 10% of the total longitudinal extent of the wiper arm element (10).
