Articulation between a wiper arm and a wiper arm mounting, and a windscreen wiper having such an articulation

Abstract

The invention relates to a articulated joint between a wiper arm (1) and a wiper arm mounting (4) that can be attached to a wiper shaft (5), comprising articulation elements (11, 4.3) on both the wiper arm (1) and the wiper arm mounting (4), a hinge pin (7) on a first articulation element (4.3), and at least one bearing opening (12) in a second articulation element (11) for receiving the hinge pin (7). The bearing opening (12) is open at one side to allow the second articulation element (11) to be slid onto the hinge pin (7) in a radial direction, specifically in a radial direction with respect to the axis of the bearing opening (12) and in a line running perpendicular to the longitudinal extension of the wiper arm (1).

Description

technical field [0001] The invention relates to a joint between a brush rod and a brush rod holder of a brush arm according to the preamble of claim 1 and to a brush arm having such a joint according to the preamble of claim 13 . Background technique [0002] The wiper arm of a wiper is known in various embodiments, which essentially comprise a brush rod holder or holder for the brush arm and a brush rod, which are arranged on the wiper shaft. The brush bar is articulated to the brush bar frame for pivoting between the operating position and the maintenance position, and conventional brush blades are attached to the brush bar. In particular, an embodiment is also known which makes it possible to mount the brush rod on the brush rod holder in the area of ​​the joint, to be precise by pushing the brush rod radially into the bearing hole which is open laterally. Set on the hinge pin on the brush holder. The bearing bore opens here in the direction of the longitudinal extensio...

AI Technical Summary

Problems solved by technology

[0004] Since, in the known embodiment, the bearing bores open in each case in the direction of the longitudinal extension of the brush bar at least on the brush bar in the operating position, when lateral forces act on the brush bar, for example when cleaning appliances or when wipers are in operation During the increased forces that develop between the brush rod and the brush rod holder, there is the risk that the brush rod will become detached from the brush rod holder. Pressing out or pulling out of the joints on the

In order to solve this problem, it is also proposed to provide a safety tab on the brush bar, which engages the brush bar holder from the rear in the region of the gap in the operating position of the brush bar, but this means that complex structures and / fabrication
