Embodiment Construction

[0019] This arm head 3 comprises a pin 4 on which the arm itself is articulated so as to pivot in a plane substantially perpendicular to the window.

[0020] Housed in the arm head is a detachable device for connecting the windscreen wiper arm to a drive shaft driven in rotation about its longitudinal axis 5 . The arrangement comprises means 6 which are physically mounted to the arm and which provide the connection of the arm to the drive shaft in the normal windscreen wiper operating position. When the drive shaft is stationary, the device is deformable under the action of a moment applied to the arm, so that the arm pivots about the longitudinal axis 5 of the drive shaft, and the device is able to pass through the unique lock of the arm to the drive shaft. Reposition to normal operating position from locked relative position.

[0021] The deformable means 6 comprises two stacked elastic sheets 6A, 6B, each consisting of a metal spring sheet. These spring pieces are physica...

Abstract

The invention concerns an arrangement for self-releasing connection of a windscreen wiper arm on a driving shaft driven in rotation about its longitudinal axis (5), comprising a device integral with the arm and connecting the arm (3, 4) and the driving shaft in the windscreen wiper normal operating position, said device being deformable under the effect of a torque applied to the arm and tending to cause it to pivot about the axis of rotation (5) of said shaft, when said shaft is immobile, and capable of being repositioned in normal operating position by the relative locked positioning of the arm and the driving shaft. The invention is characterized in the said relative positioning of the arm (1, 3) and of the shaft constitutes a single operation.

Description

technical field [0001] The invention relates to a detachable device for connecting a wiper arm on a drive shaft. Background technique [0002] Motor vehicle windscreen wiper arms are usually connected to a drive shaft that powers their pivotal movement within the wiping range of the vehicle window, the longitudinal axis of the arm being substantially perpendicular to the axis of rotation of the drive shaft. Furthermore, in order to gain access to the wiper blade held by the arm, the arm can be pivoted in a plane substantially perpendicular to the window, mainly for correcting or changing the wiper blade. The windscreen wiper may comprise an arm head mounted on the drive shaft and on which arm itself is hinged for pivoting in said plane substantially perpendicular to the window. [0003] In some cases, such as when a motor vehicle is washed with a roller or when there is ice or snow on the windows, the arm experiences significant moments that tend to pivot the arm about the ...
