Abstract

The arm (1) is intended to be mounted, at one end, on a drive shaft (6a) capable of imparting to it an alternating rotational movement, the said arm being equipped, at its end (16) remote from the drive shaft, with a windscreen wiper blade (21) and being articulated, in the vicinity of the drive shaft, on an axis (C--C) which is substantially parallel to the surface of the windscreen to be wiped in order to allow the arm to be lifted, which arm is returned by elastic means. The arm (1) is formed of a tubular element (2); an orientation member (12) which is fixed with respect to the supporting structure of the windscreen is provided in the vicinity of the shaft (6a), and includes a fixed support point (P); the end (16) of the arm carries a lever (17) mounted so that it can rotate about an axis (18) which is substantially parallel to the shaft (6a), the windscreen wiper blade (21) being carried by this lever ( 17); linkage means (L) are provided inside the tubular element (2) between the abovementioned fixed support point (P) and a point (20) on the lever (17) in order to keep this lever (17) parallel to a fixed direction (D) when the arm (1) rotates, the windscreen wiper blade (21) connected to the lever (17) thus moving parallel to itself.
