Furthermore, it is provided that the wiper arm element (12) consists of two separate components (14, 16), namely a first component (14), which is connected to the adapter element (18), and a second component (16), which attaches to the first component (14) on the side facing away from the adapter element (18), and that the first component (14) is formed from a profile strip (37) having a U-shaped cross section, wherein the two components (14, 16) overlap in a longitudinal direction in a first connection area (24).

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.

A windscreen wiper arm comprising a wiper arm member having a substantially U-shaped cross-section arranged to be pivotally connected to a mounting head mounted on a drive shaft, and a wiper rod having a first end rigidly connected to and extending inside said wiper arm member and a second end arranged to be connected to an elongated wiper blade to be placed in abutment with a windscreen to be wiped. The windscreen wiper arm includes a nozzle for spraying a washing liquid onto said windscreen to be wiped, where said nozzle is detachably connected to said wiper rod inside the U-shaped cross-section of the wiper arm member.

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.

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 wiper arm assembly (4) including a wiper arm (11) configured to support a wiper blade; a mounting member (9) configured to be secured to a wiper shaft (7); a spring member (14) including a first spring end portion (14.1) operatively connected to the wiper arm (11) and a second spring end portion (14.2) operatively connected to the mounting member (9); and a force adjusting device (15) configured to adjust the biasing force applied by the spring member (14) to the wiper arm (11). The force adjusting device (15) includes an actuating member to which is connected the first spring end portion (14.1), the actuating member being movably mounted on the wiper arm (11) between a first adjusting position and a second adjusting position, and being configured to displace the first spring end portion (14.1) between a first spring position in which the spring member (14) applies a first biasing force to the wiper arm (11) and a second spring position in which the spring member (14) applies a second biasing force to the wiper arm (11) which is higher than the first biasing force.
